Business Gas and Electricity Suppliers 2026 Compared

Last updated: Monday 2 November 2026

Which suppliers sell business gas and electricity? Most of the big names do. In Bionic’s October 2026 supplier panel, British Gas, BG Lite, EDF, E.ON Next, ScottishPower, Smartest Energy, Valda Energy, Yorkshire Gas & Power and Yu Energy all quoted for both fuels, but the cheapest quote for each fuel came from different suppliers. As of 2 November 2026, for a six-bed HMO using 9,000kWh of electricity and 20,000kWh of gas, those panel prices range from about £4,569 a year for the best pair to £6,127 for the dearest, a gap of roughly £1,560. To compare fairly, send every supplier the same MPAN, MPRN, yearly kWh and contract end date, then compare the total yearly cost rather than the unit rate. This SwitchSquid guide lists who supplies what, what to have ready for a quote, when dual fuel makes sense and worked examples for a 30-bed care home and a six-bed HMO. If you request quotes through this page, we may be paid by the supplier you choose; it does not change the price you are quoted.

Business gas and electricity suppliers compared

Bionic, a business energy broker, publishes the prices its panel of suppliers quoted between 1 and 12 October 2026. The figures include Bionic’s maximum commission and are based on a business using about 22,223kWh of gas and 9,234kWh of electricity a year, so a direct or lower-commission quote can come in lower. They are a guide to who is competitive, not a price every business will be offered.

Two things stand out. First, the lowest unit rate is not the cheapest deal for a small site: SEFE’s 5.8p gas comes with a standing charge of more than £11 a day. Second, no single supplier is cheapest for both fuels. Bionic’s size-band averages for the same period put micro businesses at 28.4p per kWh and 58.0p a day for electricity, and small gas users at 8.5p per kWh and 49.5p a day. Our guide to the best price business electricity suppliers covers electricity in more depth.

What you need to get a business gas and electricity quote

Suppliers and brokers price on your real usage and meter details. Have these ready before you ask for quotes, and send the same set to everyone so the prices are comparable.

• MPAN: the electricity supply number on your bill, sometimes shown as a box starting with an S.

• MPRN: the gas meter point reference number, also on your gas bill.

• Yearly usage in kWh: for each fuel, from the last 12 months of bills or meter readings.

• Contract end date: and any notice period, so you know when you can move without fees. Our contract end checker helps.

• Business details: legal name, company or sole trader status, site address and who is authorised to sign.

• VAT and levy position: whether any supply qualifies for reduced-rate VAT or Climate Change Levy relief, so quotes show the right taxes.

If a broker requests your data, you will usually sign a letter of authority.

Dual fuel or separate suppliers: which is cheaper?

A dual fuel contract puts gas and electricity with one supplier. Separate contracts let you pick the cheapest supplier for each fuel. Here is how the panel prices above work out for a six-bed HMO using 9,000kWh of electricity and 20,000kWh of gas a year, including standing charges.

In this example, splitting the fuels saves only about £48 a year over the best dual fuel option, while picking the wrong supplier for both costs about £1,560 more. That is the real lesson: comparing several suppliers matters far more than whether you choose dual fuel.

• Dual fuel with one supplier: one account and one renewal date, which suits busy owners and small sites, though the price is sometimes slightly higher.

• Separate suppliers: can be the cheapest for each fuel, which suits larger users where small differences add up, but you have two accounts and two end dates to track.

See our business dual fuel page, and our guides to comparing business gas and comparing business electricity.

Unit rate or standing charge: why the cheapest supplier depends on usage

A low unit rate with a high standing charge suits big users, and the reverse suits small ones. In the panel, SSE quoted the lowest electricity unit rate at 23.6p per kWh but a standing charge of 310.7p a day, against EDF’s 28.3p and 60.8p. If those same rates applied, SSE would only be cheaper above about 19,400kWh a year. Below that, EDF’s lower daily charge wins.

So always work out the total: multiply the unit rate by your yearly kWh, add 365 days of standing charge, then compare. Our guide to the business gas standing charge explains the daily fee in more detail.

Worked example: a 30-bed care home

This example is illustrative. Using the per-bed figures in our care home energy costs per bed guide, a 30-bed home might use about 150,000kWh of electricity and 225,000kWh of gas a year.

At this size, every penny off the gas rate is worth more than a penny off electricity, because the home uses more gas. Quotes for a site this large are priced individually, so ask for both fuels at once and compare a dual fuel offer against the best separate prices. Care homes should also check VAT, as fuel for qualifying residential care can get relief; see our care home energy VAT guide, our care home gas contract guide and our care home energy page.

Worked example: a six-bed HMO

This example is also illustrative and uses the same usage as our HMO energy costs per room guide: 9,000kWh of electricity and 20,000kWh of gas a year.

• Electricity: 9,000kWh at Bionic’s micro business average of 28.4p per kWh and 58.0p a day comes to about £2,768 a year. Every 1p per kWh is worth about £90.

• Gas: 20,000kWh at Bionic’s small business average of 8.5p per kWh and 49.5p a day comes to about £1,881 a year. Every 1p per kWh is worth about £200.

• Total: about £4,649 a year at these averages.

The best supplier pair in the panel comes in at about £4,569, roughly £80 below these averages, while the dearest pair is about £1,480 above them. If the bills are in your name on a business contract, check whether the tenants’ use qualifies for reduced-rate VAT, as our HMO electricity VAT guide explains. Our guides to HMO communal boiler gas contracts and the HMO landlord energy page have more detail.

Business size, contract types and your protections

Ofgem says you count as a microbusiness if you have fewer than 10 employees and a turnover or balance sheet of no more than £2 million, or if you use up to 100,000kWh of electricity or 293,000kWh of gas a year. Microbusinesses get extra protections, including clear contract information and renewal prices before the contract ends. A small business has 11 to 50 employees, or uses up to 200,000kWh of electricity or 500,000kWh of gas a year.

• Fixed-rate: unit rates and standing charges stay the same for the contract.

• Variable-rate: prices can move with the wholesale market.

• Deemed and out-of-contract rates: what you pay if you move in without a contract or your fix ends without a new deal. Ofgem says these are usually more expensive. See our guide to deemed rates.

• Rollover contracts: some renew automatically for a fixed term, often 12 months, possibly at a higher rate.

Ofgem also points out that there is no cooling-off period once you agree a business energy contract, and that brokers paid by a supplier must belong to an approved redress scheme. Ask any broker or comparison service which suppliers it covers and how it is paid. Our broker vs direct guide explains the trade-offs.

How to compare business gas and electricity quotes

1. Gather your MPAN, MPRN, yearly kWh and end date.

2. Ask for quotes on both fuels together and separately. That shows whether dual fuel costs you anything.

3. Compare the total yearly cost. Include standing charges, and check whether quotes include VAT and the Climate Change Levy.

4. Check the contract length and end terms. Note the notice period and what happens at renewal.

5. Ask about commission. Get it in pence per kWh or as a total.

6. Agree the new contract before your current one ends. That avoids out-of-contract rates.

Fit summary

• Choose dual fuel if: the price is within a few pounds of the best separate quotes and you value one account and one renewal date.

• Choose separate suppliers if: you use a lot of energy and the split saves a meaningful amount.

• Act now if: your contract ends in the next six months, or you are on deemed or out-of-contract rates.

• Care homes and HMOs: check VAT relief before you compare, as it changes the final bill more than most rate differences.

Important conditions

• Bionic’s figures are panel averages from 1 to 12 October 2026 and include its maximum commission. Your quote will depend on your usage, meter, location and credit position.

• The panel shows which suppliers quoted for each fuel through Bionic; some suppliers may offer other fuels elsewhere.

• The worked examples are illustrations, not quotes.

• Business contracts have no cooling-off period once agreed, so read the terms before you sign.

Final decision card

Most large business suppliers sell both gas and electricity, but the cheapest pair often comes from two different firms, and the gap between the best and worst quotes can be more than £1,500 a year even for a six-bed HMO. Send every supplier the same MPAN, MPRN, kWh and end date, compare total yearly cost, and decide on dual fuel only once you have seen both options. Our form asks for exactly these details, and you can ask Squid AI if you are unsure what to include.

FAQ

Which suppliers do business gas and electricity?

Most large suppliers do, including British Gas, EDF, E.ON Next, ScottishPower, Smartest Energy, Valda Energy, Yorkshire Gas & Power and Yu Energy, all of which quoted for both fuels in Bionic’s October 2026 panel. Some suppliers focus on one fuel, so ask for both when you request quotes.

Is it cheaper to have gas and electricity with the same business supplier?

Not always. In our HMO example, splitting electricity and gas between two suppliers saved about £48 a year over the best single-supplier option. Choosing the right suppliers matters far more than choosing dual fuel.

What do I need to compare business gas quotes?

You need your MPRN, yearly gas usage in kWh, contract end date and business details. If you want electricity quoted too, add your MPAN and yearly electricity usage.

Who is the cheapest business electricity supplier?

It depends on your usage. In Bionic’s October 2026 panel, EDF was cheapest for a site using 9,000kWh a year, while SSE’s lower unit rate would win above about 19,400kWh if the same rates applied. Compare the total yearly cost at your own usage.

How much does business gas cost per kWh?

Bionic’s October 2026 averages range from 8.5p to 8.8p per kWh depending on business size, with standing charges of 44.9p to 67.3p a day. Government figures for April to June 2026 put the smallest gas users at 9.31p per kWh including standing charges and the Climate Change Levy.

Is there a cooling-off period on business energy contracts?

No. Ofgem says there is no cooling-off period once you agree a business energy contract. Check the price, length and end terms before you sign.

Should a care home or HMO use a broker?

A broker can save time by asking several suppliers at once, but its commission is built into your rates. Ask for the commission in pence per kWh and check the broker belongs to an approved redress scheme.
