Your office might be a laptop on the kitchen table, a desk in the spare room or a workshop at the bottom of the garden. Whichever it is, the electricity bill keeps arriving, and it is hard to tell how much of it belongs to the business.
Small business electricity prices work differently from the household bills you know. Business rates are not capped, the VAT rules are different, and the right deal depends on how your property is wired and metered, not just how many cups of tea you make.
This article explains whether your home business needs a business tariff, what business electricity rates look like this October, three worked examples, and how to get a business electricity quote without losing a week to paperwork.
The short version
Most people who work from home stay on a domestic tariff. A business contract is for a separate business supply or mostly business use.
Benchmark unit rates for micro-sized business sites run from about 27p to 32p per kWh before VAT, plus a daily standing charge.
Sites using under 33 kWh a day can qualify for reduced VAT, which is 0% on electricity until 31 March 2027.
A business electricity quote takes minutes when you have your address, usage and meter details to hand.
Do home-based businesses need a business electricity contract?
Often, no. Ofgem says most people who work from home are on a domestic contract and do not need a separate business one. That changes if your business has its own supply, such as a converted garage, studio or garden unit with a business meter. Then you need a business contract.
When a domestic tariff usually fits
If you work at a desk and one meter serves the whole house, a domestic tariff is the sensible choice. You keep the Ofgem price cap on default tariffs, a cooling-off period on new contracts and 0% VAT on electricity until 31 March 2027.
When a business contract fits
Look at a business tariff if you have a separate business meter, run heavier equipment such as ovens or salon kit, or your supplier classes the supply as non-domestic. Some suppliers also want proof that around half or more of your use is for business.
A business tariff is not automatically cheaper, because VAT, the Climate Change Levy and standing charges can close the gap. Here is how the two compare:
Domestic tariff | Business tariff | |
|---|---|---|
Price cap | Yes, on default tariffs | No |
VAT on electricity | 0% until 31 March 2027 | 20%, or the reduced rate if you qualify |
Climate Change Levy | No | Yes, unless your use is very low |
Contract length | Often 12 months | Usually one to five years |
Cooling-off period | Yes | Rare |
Best for | Desk-based work at home | Separate or heavy-use premises |
How small business electricity prices are worked out
Your bill has a few moving parts. Knowing them explains why two quotes for the same site can look so different.
The unit rate
This is the price per kilowatt hour (kWh) you use, quoted in pence. Smaller users usually pay more per unit. Official figures analysed by Catalyst Commercial put the average micro business at 35.02p per kWh including the Climate Change Levy in early 2026, against 23.93p for larger users. Those are averages across all contracts, so a fresh fixed quote can come in lower.
The standing charge
This is a daily fee you pay whatever you use. SwitchUrEnergy’s October 2026 benchmarks put typical micro-site charges at 40p to 55p a day, which works out at roughly £146 to £201 a year.
Taxes, levies and network costs
Ofgem lists wholesale energy, network charges, government schemes, supplier costs and taxes as the building blocks of a business rate. Cornwall Insight says non-wholesale charges typically make up around 60% of a business electricity bill, so a falling wholesale price does not always reach your invoice. The Climate Change Levy is 0.801p per kWh from April 2026, but low-use sites under 33 kWh a day are generally exempt.
What are typical business electricity rates for a home-based business?
No official rate exists for home-based businesses, so micro-business benchmarks are the best guide. Business electricity rates are not capped, and they shift with wholesale markets, your region, meter type, credit profile and contract length. Treat the figures below as ranges, not promises.
Size band | Typical annual use | Strong unit rate | Typical range | Standing charge |
|---|---|---|---|---|
Micro | 5,000 to 15,000 kWh | 27.0p or below | 27.1p to 32.0p | 40p to 55p a day |
Small | 15,001 to 30,000 kWh | 26.0p or below | 26.1p to 31.0p | 45p to 65p a day |

Other panels sit in the same area. Bionic’s July 2026 panel data shows micro sites at about 29.7p per kWh with a 57.1p daily charge. Ofgem’s domestic cap for October to December 2026 averages 26.32p per kWh with a 54.83p daily charge, before any VAT. The chart puts them side by side.
Sources: Ofgem (domestic cap, October to December 2026, before VAT), SwitchUrEnergy October 2026 ladder, Bionic panel data (July 2026), DESNZ figures via Catalyst Commercial (Q1 2026, includes the Climate Change Levy) and Bionic (out-of-contract rate, July 2026).
A strong business rate and the domestic cap sit within a penny of each other, so the real savings come from avoiding the expensive end of the range. The 40p bar is the one to fear. The same panel puts out-of-contract rates at 40p per kWh with a standing charge of about £2.54 a day. Drifting onto one by accident is the costliest mistake a small business can make.
Three examples: what home-based businesses actually pay
These illustrations use the benchmarks above. They are not quotes, and your postcode, meter and credit profile will move the numbers.
Home business | Annual use | Likely supply | Illustrative annual cost before VAT |
|---|---|---|---|
Freelance designer in a spare room | 3,500 kWh | Domestic | About £1,121 at average cap rates |
Beauty studio in a converted garage | 8,000 kWh | Business, separate meter | £2,335 at 27p and 48p a day, up to £2,735 at 32p |
Home baker with a garden kitchen unit | 18,000 kWh | Business, separate meter | £4,881 at 26p and 55p a day, up to £5,781 at 31p |
The freelance designer stays domestic. At average cap rates the bill is about £1,121 a year with no VAT until 31 March 2027, and a business tariff would add little. The smarter move is claiming the work share of the bill as an expense (see tip 6 below).
The beauty studio uses about 22 kWh a day, under the 33 kWh limit, so reduced VAT (now 0%) and a Climate Change Levy exemption should apply. The gap between a 27p and a 32p rate is £400 a year.
The home baker uses about 49 kWh a day, above the limit, so 20% VAT (reclaimable if you are VAT-registered) and the levy apply. Here the gap between a strong and a high rate is £900 a year, which is why comparing matters most.

How to get a business electricity quote
A business electricity quote is quick when you have the right details to hand.
What to have ready
The supply address and postcode
Your MPAN, the electricity meter number printed on your bill
Annual usage in kWh from a recent bill
Your meter type, such as standard, smart or half-hourly

Three steps with SwitchUrEnergy
Tell us about your business. Enter your details and usage in our quote form.
Compare personalised quotes side by side. Check the unit rate, standing charge, contract length, exit fees and whether VAT and the Climate Change Levy are included.
Pick your plan and we manage the switch. Business switches typically complete within two to six weeks. We use a Letter of Authority only to request your usage and contract details, and it never lets us sign a contract without your consent.
Choose your term deliberately. A fixed contract locks your rates, usually for one to five years. A variable deal moves with the market. Rolling onto a deemed or out-of-contract rate costs the most. Before you sign anything, our guide to the 8 questions to ask a commercial electricity supplier is worth five minutes.

Seven ways to lower your electricity costs
Work out your business share. For one typical week, note when equipment is used for work. That evidence helps with supplier questions and tax claims.
Check your VAT and Climate Change Levy status. Sites using no more than 33 kWh a day, or 1,000 kWh a month, can qualify for the reduced VAT rate. Mixed-use premises can too when 60% or more of the supply is for domestic use, as set out in HMRC’s VAT Notice 701/19. Suppliers may ask for a certificate.
Do the standing charge sum. Multiply your kWh by the unit rate, then add 365 days of standing charge. A low unit rate with a heavy daily charge can cost light users more.
Diarise your renewal window. Many suppliers let you agree a new deal months before your contract ends. Shopping early helps you dodge out-of-contract rates.
Match the term to your budget. Fixed terms give certainty, and shorter fixes let you re-price sooner if the market eases.
Claim the work share. Sole traders can use HMRC’s simplified flat rates of £10, £18 or £26 a month, depending on hours worked at home, or claim the business proportion of actual costs. Ask your accountant which suits you.
Compare every time. On our comparison table, estimated annual bills for a 10,000 kWh site range from £2,829 to £3,232 before VAT, a gap of about £404 for identical usage.

Frequently Asked Questions (FAQs)
Here are answers to the questions we hear most often.
Can I run a business from home on a domestic tariff?
Usually, yes, and most home workers do. If your business has a separate business meter, or your supplier says the supply is non-domestic, you need a business contract instead.
Is business electricity cheaper than domestic electricity?
Not always. Business unit rates can be lower, but VAT, the Climate Change Levy and standing charges can cancel the saving. Compare annual cost, not unit rate alone.
What are typical small business electricity prices per kWh?
Our October 2026 benchmarks put micro sites at about 27p to 32p per kWh before VAT. Only a live quote shows your real figure.
Is there a price cap on business electricity?
No. Ofgem confirms that business energy customers are not protected by the energy price cap.
Do I pay VAT on business electricity at home?
Most businesses pay 20%. Sites using under 33 kWh a day can pay the reduced rate, which is 0% on electricity until 31 March 2027. Ask your supplier to confirm what applies to you.
Is a business electricity quote free?
Yes. Comparing with SwitchUrEnergy is free and carries no obligation to switch.
How long does switching take?
Typically two to six weeks for business accounts, and your supply continues without interruption.
Final Words
Most home-based businesses will stay on a domestic tariff, and that is perfectly sensible. If your business has its own meter or heavy electricity use, small business electricity prices, business electricity rates and contract terms deserve a proper look, because the gap between a strong deal and a weak one runs into hundreds of pounds a year.
