If your business is in the market for a gas-supplier switch or simply wants to review its current costs, our review takes a detailed look at the offering from Avanti Gas (UK) – the tariffs and pricing, features, strengths and points to watch.
Who is Avanti Gas?
Avanti Gas specialises in supplying liquefied petroleum gas (LPG) and other gas solutions to businesses across England, Scotland and Wales.
Key facts:
- Part of the UGI Corporation group.
- Offers bulk LPG, bottled gas, and for some business customers even mains-gas supply.
- Covers a wide range of commercial sectors – agriculture, catering, manufacturing, off-grid sites and more.
Why this matters for businesses:
If your site is off-grid (or partially off-grid) or uses LPG rather than standard mains gas, Avanti Gas is more specialised in those non-standard supply situations than many mainstream suppliers. That gives it a particular niche-strength. On the other hand, if you’re looking purely for standard-grid natural gas in a mainstream setting you should check how its offering compares with dedicated mains-gas specialists.

Tariff types and how pricing works
Here’s a breakdown of the types of contracts and tariff models offered by AvantiGas, and what to keep in mind.
Fixed-term contracts
These are contracts where the unit cost (pence per kWh or per litre/tonne depending on fuel type) and standing charges are locked for a given period (commonly 12 months up to three years or more).
Benefits:
- Predictable costs: helpful for budgeting.
- Protection against short-term spikes in wholesale gas/LPG prices.
Things to check:
- Does your contract include any exit fee if you leave before term ends?
- Is your usage aligned with the contract size (you may pay more if you fall outside the agreed band).
- Fixed rate helps, but you still pay taxes, standing charges, delivery etc.
Variable rate contracts
Under these you pay a unit rate which tracks an industry index or wholesale cost, meaning your cost moves up or down depending on the market.
Benefits:
- Potential to benefit when wholesale prices drop.
- More flexibility if your usage is uncertain or you expect to scale up/down.
Caveats:
- Greater price risk – if wholesale costs rise you carry the increase.
- Harder to budget for long term.
Deemed or out-of-contract (tariff) rates
If your fixed contract ends and you haven’t signed a new one, your supply may roll into a “tariff” or “deemed” rate. These tend to be less favourable in terms of unit cost.
Important note for businesses:
It is often worth proactively securing a new contract before the fixed term ends, rather than defaulting into a higher-cost deemed arrangement.
What determines the price?
For Avanti Gas’s LPG business supply the price is influenced by many factors: international market prices, exchange rates, transport/distribution costs, taxes and duties and the supplier’s margin.
It’s worth noting for LPG that some support schemes or price caps applicable to mains gas may not apply.
Features of Avanti Gas’s business offering
Beyond tariff structure, here are features that matter when assessing the supplier.
Broad sector coverage and fuel types
AvantiGas caters to diverse sectors: catering, holiday parks, care homes, manufacturing, agriculture, warehouses – and offers solutions including bulk LPG, bottled gas, and conversions from oil or other fuels.
If your premises are off-grid or need bulk delivery and storage, the bulk LPG solutions could be a fit.
Online account, meter reading & support
- Some contracts come with automatic meter‐reading (AMR) or online account portals.
- The supplier states it offers “fast, straightforward switch” for new customers.
- 24/7 emergency line for LPG customers (important for reliability) is quoted.
Sustainability / BioLPG option
For businesses looking to reduce carbon footprint, AvantiGas offers BioLPG blends (renewable liquid gas) – you can choose a percentage blend, with certification, using existing infrastructure.
This is a distinguishing feature for forward-thinking businesses aiming for low-carbon goals.
Off-grid and conversion support
For sites currently using oil, gas-oil, solid fuel or no mains grid connection, AvantiGas offers support including installation, finance options (for large users), and full turnkey solutions.
Pricing trends and value for businesses
Although exact unit rates will vary by site size, usage profile, contract term and market conditions, here are some observations.
- Business utilities commentators list Avanti Gas as “competitive” in the LPG and off-grid sector.
- However, the pricing waypoint for the main mains-gas division appears to have been transferred: AvantiGas mains gas business supply is now being transferred to British Gas (for customers of Avanti Gas ON) – meaning new contract negotiation may now go through British Gas.
- As with many energy providers, businesses should avoid simply letting contracts roll into higher default rates.
Top tips for businesses considering AvantiGas:
- Request a detailed quote for your usage band (bulk or bottle), including all charges (unit, standing, delivery, tank rental if applicable).
- Consider contract length: if you expect usage to grow (or shrink) then ensure the contract allows for that flexibility.
- Compare fixed vs variable: if you want budget certainty pick fixed; if you expect market rates to drop and your usage is flexible then consider variable.
- Ask about any installation, conversion or tank rental charges (especially for off-grid).
- Check the exit terms: are there penalties or charges if you wish to leave?
- Use the online portal or AMR where offered, to gain visibility of consumption and spotting cost-drift.
- If sustainability is on your agenda, the BioLPG option is a valuable differentiator.
- If you already have mains-gas supply with AvantiGas, check whether your contract is now being managed by British Gas and what that means for you.
Strengths & weaknesses – how does AvantiGas stack up?
Here’s a summary of the pros and cons, from a UK-business perspective.
Strengths
- Good fit for off-grid, bulk users and sectors outside standard mains-gas customers.
- Transparent contract options (fixed, variable, tariff) with clear distinction.
- Online account and AMR tools enhance control.
- Sustainability offering via BioLPG is ahead of many peers.
Weaknesses / points to watch
- For mainstream mains-gas supply the transfer to British Gas may introduce change or complexity.
- Some reviews point to customer-service issues (as with many energy suppliers) so check service performance.
- Because LPG is more niche than mains gas, there may be fewer direct benchmarking options; ensure you compare like-for-like.
- Tariff or “deemed” rates (if you let contracts lapse) tend to be more expensive; active management is required.
Final verdict – is Avanti Gas right for your business?
If your business:
- uses LPG (bulk or bottled), especially in an off-grid or remote location; or
- is looking for a flexible fuel solution with possible future conversion from oil/solid fuel; or
- has sustainability ambitions and wants a BioLPG route
… then Avanti Gas represents a credible, well-established supplier with a clear offering, transparent tariff options and some value-add features.
However, if your business is a typical mains-gas customer in a grid-connected site and you are purely focused on the lowest possible unit cost in a highly competitive market, then you may want to benchmark several suppliers (including mainstream ones) side-by-side. In that scenario, check how the AvantiGas (or its transferred British Gas) contract stacks up on price, service and flexibility.
In short: one size does not fit all. Use the tariff structure and service features as a checklist when comparing, and make sure you’re comparing the right category of supply (LPG vs mains gas) and contract type (fixed vs variable) for your business.
FAQ
Avanti Gas generally requires a minimum bulk delivery of 500 litres, though larger customers often schedule 1,000–2,000 litres per drop to secure lower rates. Deliveries below 500 litres may attract a small-load surcharge of around £25–£35, depending on region and distance from the local depot.
Avanti Gas typically reviews fixed-term contract rates every 12 to 36 months, depending on the agreement length. Businesses on variable or indexed tariffs may see price adjustments every quarter, reflecting wholesale LPG market changes of up to ±10% in some months.

Most Avanti Gas business customers are invoiced monthly with 14- or 30-day payment terms. Larger accounts consuming over 100,000 kWh per year can negotiate 45-day terms or prepayment discounts of up to 1.5%. Late payments typically incur a 2% monthly interest charge.
Regional delivery differences can cause LPG prices to vary by 2–4 pence per litre. For example, bulk LPG may average 38 p/litre in the Midlands but 42 p/litre in northern Scotland. Transport distance, depot availability, and road access all affect the final rate per litre.
