Barbican Power, also styled as BarbicanPower, is a small UK business electricity supplier focused on renewable electricity, flexible commercial energy contracts and route-to-market services for generators. It is not a conventional mass-market business energy supplier with a large public tariff table, instant SME quote journey and thousands of visible customer reviews.
For business customers, the main appeal is likely to be renewable electricity, bespoke pricing and contract flexibility. Barbican Power says it can offer fixed energy contracts, flexible energy contracts and renewable energy contracts, with renewable supply options available through structures such as corporate PPAs, REGOs and carbon offset options.
However, Barbican Power is also a supplier where businesses should read the small print carefully. Its business prices are not published as a simple list of contracted tariffs. The only clear public rate table is for deemed or out-of-contract customers, where the unit rate is 35p per kWh and the standing charge is £25 per day per meter, excluding VAT and Climate Change Levy. That standing charge is very high compared with a typical small business energy contract, so a business should not treat Barbican Power’s deemed tariff as a normal long-term deal.

Our verdict on Barbican Power for business energy
Barbican Power is worth considering if your business wants a renewable electricity supplier with bespoke contract options rather than a standard off-the-shelf fixed tariff. Its business energy page is clearly aimed at companies that want to make a more deliberate procurement decision, choosing between fixed, flexible and renewable supply structures.
It may be particularly relevant for businesses with larger or more complex electricity requirements, multi-site portfolios, half-hourly meters, consultants or procurement teams. It may also be relevant for organisations that want a renewable electricity contract supported by traceable certificates, a corporate PPA or a more structured green supply approach.
The main drawback is limited pricing visibility. Barbican Power does not publish ordinary contracted business electricity unit rates and standing charges. The published deemed rate is clear, but it is expensive and should be treated as a fallback rate rather than a competitive contract.
Overall, Barbican Power looks like a specialist renewable electricity supplier for business customers, not a simple price-led SME supplier.

Who is Barbican Power?
Barbican Power Limited is an active UK company incorporated in April 2013. Companies House lists its business activities as trade of electricity and trade of gas through mains, although the company’s current website says it is focused on electricity supply and does not currently supply gas.
Barbican Power describes itself as a GB-based energy supplier focused on the UK’s clean energy transition. Its public proposition is built around business energy, selling energy from generators, decarbonisation support and partner relationships with consultants and brokers.
Unlike major suppliers such as British Gas, EDF, E.ON Next or ScottishPower, Barbican Power is not presented as a mass-market SME utility brand. It appears to be a smaller and more specialist supplier focused on renewable electricity and bespoke commercial energy arrangements.
Does Barbican Power supply business gas?
No, not at present. Barbican Power’s current website says it does not currently supply gas and is focused on electricity supply.
This is important because some public company data still shows gas-related activity. Companies House lists the company’s SIC codes as trade of electricity and trade of gas through mains, and Ofgem previously granted Barbican Power a gas supply licence. However, Ofgem later published a notice of revocation of the gas supply licence because the company had not commenced gas supply within one year.
For EnergyCosts.co.uk readers, the practical conclusion is simple: Barbican Power should currently be treated as a business electricity supplier, not a dual fuel supplier.
What business energy products does Barbican Power offer?
Barbican Power’s business energy offer is centred on electricity supply rather than gas.
| Product or service | Available from Barbican Power? | Notes |
|---|---|---|
| Business electricity | Yes | Main business supply product |
| Business gas | No | Not currently supplied |
| Domestic electricity | No | Business customers only |
| Fixed electricity contracts | Yes | Unit rate fixed for the contract term |
| Flexible electricity contracts | Yes | Energy bought in stages based on agreed risk approach |
| Renewable electricity contracts | Yes | Renewable options can be added to fixed or flexible structures |
| Multi-site contracts | Yes | The supplier says it can quote across multiple sites and MPANs |
| Corporate PPAs | Yes | Available as part of renewable supply or generator offtake structures |
| REGO-backed renewable options | Yes | Referenced in Barbican Power’s renewable electricity FAQs |
| Carbon offset options | Yes | Referenced as one of its renewable electricity options |
| Deemed supply | Yes | Published deemed/out-of-contract rate available |
| Instant online SME tariffs | No | Contracted prices are quote-led |
Barbican Power business electricity prices
Barbican Power does not publish a standard table of contracted business electricity prices. There is no visible list of fixed one-year, two-year or three-year unit rates, standing charges, exit fees and regional rates for ordinary business customers.
Instead, Barbican Power says it prices based on factors such as:
| Pricing factor | Why it matters |
|---|---|
| MPANs | Identifies the electricity meter and supply point |
| Site address | Regional network charges vary by area |
| Expected consumption | Higher or more predictable usage can affect pricing |
| Contract start date | Wholesale prices change over time |
| Contract term | One-year and multi-year terms can price differently |
| Product type | Fixed, flexible and renewable structures price differently |
| Interval data | Half-hourly data helps price larger sites more accurately |
| Metering type | Half-hourly and non-half-hourly sites have different cost structures |
| Risk appetite | Flexible contracts can expose the business to more market movement |
| Renewable requirement | PPAs, REGOs and other green options can affect cost |
| Credit position | Supplier credit checks may affect terms |
| Broker or consultant involvement | Commission and process requirements may affect the quote |
This quote-led model is common in the non-domestic energy market, but it means businesses need to request a live quote before they can judge whether Barbican Power is competitive.
Barbican Power deemed rates
Barbican Power publishes deemed and out-of-contract rates for customers who are supplied without an agreed contract or whose fixed term has ended.
| Barbican Power deemed electricity rate | Price |
|---|---|
| Unit rate | 35p/kWh |
| Standing charge | £25 per day |
| Standing charge basis | Per meter |
| Applies to | All meter types in any network operator area |
| VAT included? | No |
| Climate Change Levy included? | No |
| Half-hourly metering costs included? | No |
| Reactive power included? | No |
| Capacity charges included? | No |
| Billing basis | Initially estimated, then reconciled to final costs and volumes |
The £25 per day standing charge is the most striking part of the published deemed tariff. Over a full year, it equals £9,125 per meter before a single kWh of electricity is used.
Example Barbican Power deemed electricity costs
The table below shows the estimated cost of Barbican Power’s deemed electricity rate using a 35p/kWh unit rate and a £25 daily standing charge. These figures exclude VAT, Climate Change Levy and any additional half-hourly metering, reactive power or capacity charges.
| Annual electricity use | Unit rate cost at 35p/kWh | Annual standing charge | Estimated annual cost per meter |
|---|---|---|---|
| 5,000 kWh | £1,750 | £9,125 | £10,875 |
| 10,000 kWh | £3,500 | £9,125 | £12,625 |
| 15,000 kWh | £5,250 | £9,125 | £14,375 |
| 25,000 kWh | £8,750 | £9,125 | £17,875 |
| 50,000 kWh | £17,500 | £9,125 | £26,625 |
| 100,000 kWh | £35,000 | £9,125 | £44,125 |
| 250,000 kWh | £87,500 | £9,125 | £96,625 |
| 500,000 kWh | £175,000 | £9,125 | £184,125 |
| 1,000,000 kWh | £350,000 | £9,125 | £359,125 |
This illustrates why deemed rates should not be used as a long-term buying strategy. For a small business using 10,000 kWh per year, the standing charge alone would be more than twice the unit-rate cost.
Monthly cost examples on Barbican Power deemed rates
The same deemed tariff can also be viewed as an approximate monthly cost.
| Annual electricity use | Estimated annual cost | Approximate monthly cost |
|---|---|---|
| 5,000 kWh | £10,875 | £906 |
| 10,000 kWh | £12,625 | £1,052 |
| 15,000 kWh | £14,375 | £1,198 |
| 25,000 kWh | £17,875 | £1,490 |
| 50,000 kWh | £26,625 | £2,219 |
| 100,000 kWh | £44,125 | £3,677 |
| 250,000 kWh | £96,625 | £8,052 |
| 500,000 kWh | £184,125 | £15,344 |
| 1,000,000 kWh | £359,125 | £29,927 |
Again, these are not normal contract quote examples. They show what the published deemed tariff could look like if a business remained out of contract.
Barbican Power prices compared with market benchmarks
The table below uses wider UK non-domestic electricity price benchmarks. These are not Barbican Power contracted prices. They are included to give context when assessing a Barbican Power quote.
| Business electricity size band | Annual consumption | UK non-domestic average price including CCL |
|---|---|---|
| Very small | 0–20 MWh | 36.106p/kWh |
| Small | 20–499 MWh | 29.570p/kWh |
| Small/medium | 500–1,999 MWh | 28.395p/kWh |
| Medium | 2,000–19,999 MWh | 25.356p/kWh |
| Large | 20,000–69,999 MWh | 23.555p/kWh |
| Very large | 70,000–150,000 MWh | 22.514p/kWh |
| Extra large | More than 150,000 MWh | 21.128p/kWh |
| Average | All non-domestic users | 23.988p/kWh |
Barbican Power’s deemed unit rate of 35p/kWh is higher than the overall non-domestic average electricity price shown above. It is also before VAT, CCL and certain additional charges. This is another reason to treat the deemed rate as a fallback rather than a competitive tariff.
Barbican Power tariff types
Barbican Power’s business energy page describes three main ways to buy electricity.
| Tariff type | How it works | Best suited to |
|---|---|---|
| Fixed energy contract | The business fixes its unit rate for the contract term | Businesses wanting budget certainty |
| Flexible energy contract | The business buys energy in stages, usually with an agreed risk process | Larger users or businesses with consultants |
| Renewable energy contract | Renewable supply added to fixed or flexible structures | Businesses with sustainability targets |
| Deemed or out-of-contract supply | Default rate where no contract applies | Short-term fallback only |
The main distinction is between fixed and flexible procurement. Fixed contracts are easier to budget for, while flexible contracts may allow more active market management but also carry more risk.
Fixed energy contracts
A fixed Barbican Power contract is designed for businesses that want predictable electricity costs. The supplier says fixed contracts allow the customer to fix the unit rate for the full term, giving more protection when the market moves.
A fixed contract may suit:
| Business type | Why fixed pricing may help |
|---|---|
| Small offices | Simple budgeting and low procurement complexity |
| Retailers | Predictable monthly cost planning |
| Cafés and restaurants | Useful where margins are tight |
| Care providers | Helps control recurring overheads |
| Warehouses | Good for steady electricity demand |
| Multi-site SMEs | Easier budgeting across several premises |
| Charities | Supports annual budget planning |
The main risk is that a business may lock in at an unfavourable time. If wholesale prices fall after the contract is agreed, the business may not benefit until renewal.
Flexible energy contracts
A flexible contract is more sophisticated. Instead of fixing all energy at once, the business may buy energy in stages or follow an agreed procurement strategy. This can be useful where a business has internal expertise or works with a consultant.
Flexible contracts may suit:
| Business type | Why flexible pricing may help |
|---|---|
| Manufacturers | High usage makes procurement timing more valuable |
| Food producers | Large and predictable electricity demand |
| Cold storage sites | Continuous electricity use |
| Data-heavy businesses | Larger load profiles and potential market exposure |
| Multi-site operators | Portfolio-level buying opportunities |
| Procurement-led organisations | Ability to manage risk in a structured way |
| Businesses with consultants | External support can help manage buying decisions |
The drawback is that flexible procurement is not automatically cheaper. It requires governance, clear decision-making and an understanding of price risk.
Renewable energy contracts
Barbican Power says renewable supply options can be added to both fixed and flexible structures. Its business energy page refers to independently verified and traceable certificates to support sustainability reporting.
The supplier’s FAQ says it can offer 100% renewable electricity through:
| Renewable option | What it means |
|---|---|
| Corporate PPA | A supply arrangement linked to renewable generation |
| REGO options | Renewable Energy Guarantees of Origin used to evidence renewable electricity |
| Carbon offset options | Offsets used alongside electricity supply claims |
For businesses, this matters because green electricity claims are increasingly scrutinised. A business should ask exactly what form of renewable supply is being provided, whether it is backed by REGOs, whether there is a direct PPA, and what evidence can be used for ESG reporting.
Barbican Power and PPAs
Barbican Power also offers services for generators that want to sell electricity. Its “Sell Energy” page describes fixed PPAs, flexible PPAs and corporate PPAs.
A PPA, or Power Purchase Agreement, is a contract between a generator and another party for the sale of electricity. Barbican Power says PPAs are typically long-term contracts, often between 1 and 15 years.
For generators, Barbican Power may be relevant if they need a route to market for exported electricity. For business energy buyers, its PPA capability may matter because a corporate PPA can support stronger renewable electricity claims than a generic green tariff.
Barbican Power PPA options
| PPA type | How Barbican Power describes it | Best suited to |
|---|---|---|
| Fixed PPA | Fixes a price or pricing structure for an agreed term | Generators wanting revenue certainty |
| Flexible PPA | Allows generators to manage price exposure over time | Generators with active market management |
| Corporate PPA | Links generation to business demand through a corporate structure | Generators and buyers wanting longer-term renewable arrangements |
Barbican Power says generators need more than 0.5 GWh per year of generation capacity to supply electricity to Barbican Power. That is equal to 500,000 kWh per year.
Who is Barbican Power best for?
Barbican Power is most likely to be relevant for businesses that want more than a basic tariff.
| Business need | Barbican Power fit |
|---|---|
| Renewable electricity | Strong |
| Standard gas and electricity dual fuel | Weak |
| Quick SME quote comparison | Limited |
| Bespoke electricity contract | Strong |
| Flexible procurement | Strong |
| Corporate PPA support | Strong |
| Multi-site electricity supply | Potentially strong |
| Microbusiness low-cost tariff | Unclear |
| Sustainability reporting | Potentially strong |
| Public customer review evidence | Limited |
For a very small business, the lack of simple published contracted prices is a drawback. For a larger or more sustainability-focused business, the bespoke approach may be more useful.
Barbican Power for small businesses
Barbican Power may be suitable for small businesses that specifically want renewable electricity and are comfortable requesting a bespoke quote. However, it is not as straightforward as some small business suppliers that publish simpler quote journeys and standard fixed tariffs.
A microbusiness should pay particular attention to:
| Issue | Why it matters |
|---|---|
| Standing charge | Fixed daily costs can be punitive for low users |
| Contract length | Long contracts can be hard to exit |
| Renewal terms | Out-of-contract rates can be expensive |
| Deemed rates | Barbican Power’s deemed standing charge is high |
| VAT and CCL | Prices may be quoted excluding taxes |
| Broker commission | Commission may be built into the unit rate |
| Green evidence | Important if the business wants to make renewable claims |
| Payment terms | Direct debit and credit checks may apply |
| Customer service route | Smaller suppliers may have different support capacity |
Small businesses should compare Barbican Power against at least three other electricity quotes before signing.
Barbican Power for larger businesses
Barbican Power may be more interesting for larger electricity users, particularly where the business has a consultant, procurement process or sustainability target.
Larger businesses should consider Barbican Power if they need:
| Requirement | Barbican Power relevance |
|---|---|
| Multi-site electricity supply | The supplier says it can quote across multiple sites and MPANs |
| Half-hourly data pricing | Interval data can help produce more accurate pricing |
| Flexible procurement | Barbican Power offers flexible contracts |
| Renewable energy reporting | Traceable renewable certificates are referenced |
| PPA-linked electricity | Corporate PPA options may be available |
| Consultant-led procurement | Barbican Power says it works with consultants and procurement teams |
| Renewable generator relationships | PPA services are offered for generators |
The larger the electricity volume, the more important it is to compare contract structure rather than headline unit rate alone.
Barbican Power customer reviews
There appears to be limited public customer review data for Barbican Power compared with better-known suppliers. This is not surprising for a smaller and newer-facing business energy supplier, especially one that appears to be building a more specialist commercial customer base.
For buyers, this means public review scores should not be the main decision tool. Instead, businesses should ask Barbican Power for:
| Evidence to request | Why it matters |
|---|---|
| Example customer references | Helps understand service quality |
| Account management process | Important for billing and contract issues |
| Escalation route | Useful if something goes wrong |
| Billing examples | Shows how clear invoices are |
| Renewal process | Helps avoid deemed rates |
| Service-level expectations | Important for multi-site customers |
| Broker feedback | Useful if using a consultant |
| Complaints process | Important for dispute handling |
Barbican Power customer service
Barbican Power positions itself as customer-focused and says it puts customers at the centre of what it does. Its website also says it works with consultants, brokers and procurement teams, while keeping account ownership and escalation routes clear.
As a licensed electricity supplier, Barbican Power must meet relevant industry rules and certain guaranteed standards of performance. Its standards page says some standards mainly apply to microbusiness customers and that compensation may be payable where a guaranteed standard applies and is not met.
The website lists £30 account credits for certain missed supplier appointments and late pass-through of network compensation, with additional £30 credits if payment is not applied within the required timescale.
Contract terms to check before signing
Before signing a Barbican Power contract, businesses should check the following details.
| Contract detail | What to check |
|---|---|
| Unit rate | The exact p/kWh rate for each meter and time band |
| Standing charge | The daily charge per MPAN |
| Contract length | Start date, end date and fixed term |
| Product type | Fixed, flexible or renewable |
| Renewable evidence | REGOs, PPA documentation or certificate details |
| Pass-through charges | Which costs can change during the contract |
| Half-hourly costs | Metering, data, capacity and reactive power charges |
| VAT and CCL | Whether quoted prices include or exclude taxes |
| Broker commission | Whether commission is included in the quoted rate |
| Payment method | Direct debit, payment terms and late payment charges |
| Credit checks | Deposit or security requirements |
| Renewal process | How to avoid out-of-contract rates |
| Deemed rate | What applies if no new contract is agreed |
| Exit fees | Costs for early termination |
| Multi-site terms | Whether sites are priced separately or bundled |
| Consumption tolerance | Whether usage outside forecast creates extra costs |
The deemed rate is particularly important. A customer whose contract expires could face a 35p/kWh unit rate and a £25 daily standing charge per meter unless a new contract or switch is arranged.
Barbican Power price risks
Barbican Power is transparent about its deemed tariff, but the published rates also highlight several risks.
| Risk | What it means for businesses |
|---|---|
| High deemed standing charge | £25 per day equals £9,125 per year per meter |
| VAT and CCL excluded | Final billed cost may be higher |
| Half-hourly extras | Metering, reactive power and capacity charges can be added |
| Estimated billing | Charges may be reconciled later |
| No public contracted rates | You need a quote to compare properly |
| Flexible contract risk | Market timing can improve or worsen outcomes |
| Renewable premium risk | Stronger green options may cost more |
| Contract expiry risk | Missing renewal deadlines can be expensive |
These risks do not mean Barbican Power is a poor supplier. They mean the contract needs to be assessed carefully before signing.
Barbican Power compared with other green business suppliers
Barbican Power sits in a different part of the market from some well-known green energy suppliers.
| Supplier | Business electricity | Business gas | Main positioning |
|---|---|---|---|
| Barbican Power | Yes | No | Bespoke renewable electricity, fixed/flexible contracts and PPAs |
| 100Green | Yes | Yes | Renewable electricity and green gas |
| Good Energy | Yes | Yes | Established green energy supplier |
| Ecotricity | Yes | Yes | Green electricity and green gas focus |
| Bryt Energy | Yes | No | Zero-carbon electricity for businesses |
| Drax | Yes | No | Renewable electricity and large business supply |
| SmartestEnergy | Yes | No | Renewable electricity and generator services |
| Brook Green | Yes | Yes | Larger commercial and industrial supply |
If your business needs gas as well as electricity, Barbican Power is unlikely to be a complete solution. If your business only needs renewable electricity, particularly with more tailored procurement, it may be worth including in a supplier comparison.

How to get a Barbican Power quote
To get an accurate Barbican Power quote, businesses should prepare:
| Information needed | Why Barbican Power may need it |
|---|---|
| MPAN | Identifies the electricity supply point |
| Site address | Needed for network and regional charges |
| Current supplier | Helps with switching and contract timing |
| Contract end date | Avoids termination or renewal issues |
| Annual electricity use | Key driver of price |
| Half-hourly data | Useful for larger or settled meters |
| Recent bill | Confirms current rates and meter details |
| Preferred contract length | Affects fixed-price options |
| Product preference | Fixed, flexible or renewable |
| Sustainability requirements | Needed for REGO or PPA options |
| Multi-site list | Required for portfolio quotes |
| Credit information | May affect contract terms |
| Broker details | Relevant if using a consultant |
Businesses should avoid giving only estimated consumption if actual kWh data is available. A quote based on poor data can make suppliers look cheaper or more expensive than they really are.
What to ask Barbican Power before signing
Before agreeing a contract with Barbican Power, ask:
- What is the exact unit rate for each meter?
- What is the daily standing charge per MPAN?
- Are prices excluding VAT and Climate Change Levy?
- Is the contract fixed or flexible?
- Which costs are fixed and which are passed through?
- What renewable evidence is included?
- Are REGOs included?
- Is the supply linked to a corporate PPA?
- Are carbon offsets used?
- What happens if actual consumption differs from forecast?
- Are half-hourly metering costs included?
- Are capacity charges included?
- Are reactive power charges included?
- Is broker commission included in the price?
- Are there exit fees?
- What happens when the contract ends?
- How can the business avoid deemed rates?
- What billing support is available?
- What is the complaints process?
- Who is the account contact?
These questions are especially important because Barbican Power offers more than one type of contract. A fixed contract and a flexible contract can have very different risk profiles.
Is Barbican Power good value?
Barbican Power could be good value for the right type of customer, but there is not enough public contracted tariff data to judge its pricing without a quote.
For small businesses, the key test is whether Barbican Power’s quote is competitive against mainstream fixed business electricity contracts. For larger businesses, the key test is whether the contract structure, renewable evidence and procurement flexibility justify the price.
Barbican Power’s deemed rate does not look attractive as a long-term option because of the 35p/kWh unit rate and £25 daily standing charge. However, deemed rates are not the same as negotiated contract prices, so they should not be used as the only measure of the supplier’s competitiveness.
Barbican Power alternatives
Businesses considering Barbican Power may also want to compare:
| Supplier type | Alternatives to compare |
|---|---|
| Green electricity suppliers | Bryt Energy, Good Energy, Ecotricity, Drax, SmartestEnergy |
| Green electricity and gas suppliers | 100Green, Good Energy, Ecotricity |
| Mainstream SME suppliers | British Gas, EDF, E.ON Next, ScottishPower, Octopus Energy |
| Larger commercial suppliers | Brook Green, TotalEnergies, SSE Energy Solutions, npower Business Solutions |
| PPA-focused suppliers | Axpo, Statkraft, SmartestEnergy, Drax, EDF |
| Broker-led comparison | Bionic, Love Energy Savings, Utility Bidder and other business energy brokers |
The right comparison set depends on whether the business wants the cheapest electricity, the strongest green credentials, a flexible procurement strategy or a PPA-backed renewable structure.
Final verdict: should your business choose Barbican Power?
Barbican Power is worth considering if your business wants renewable electricity and is comfortable with a bespoke quote process. It may be a good fit for businesses with multiple sites, higher electricity usage, a consultant-led buying process or a clear sustainability requirement.
It is less suitable for businesses that want a simple dual fuel tariff, instant online prices or the lowest possible standing charge. It is also not currently suitable for businesses that need one supplier for both electricity and gas.
The most important advice is to avoid falling onto deemed or out-of-contract rates. Barbican Power’s published deemed rate includes a £25 daily standing charge per meter, which can make costs very high for low-usage businesses.
For EnergyCosts.co.uk readers, Barbican Power should be treated as a specialist renewable electricity supplier. Request a quote, compare the full annual cost against other suppliers, check the renewable evidence, and make sure the renewal process is clear before signing.
