Business energy price cap UK: does Ofgem’s domestic cap cover SMEs?

Last updated: Tuesday 6 October 2026 (Europe/London).
Next update: when Ofgem changes microbusiness or non-domestic guidance, or when the next domestic cap announcement (due by 25 November 2026) shifts the household context figure.
By: Switch Editorial Team, Switch Squid Ltd

As of 6 October 2026, Ofgem’s energy price cap does not apply to most UK business energy contracts. It is a domestic protection for household default tariffs. The household typical dual-fuel figure for 1 October to 31 December 2026 is about £1,723 a year — that number is useful context for your home bill, not a ceiling on your shop, office, café or warehouse. Microbusinesses get clearer contract, renewal and broker rules instead of a rate cap. Out-of-contract and deemed rates can still be expensive if you miss a renewal.

The short answer

• No domestic-style price cap on business energy. Ofgem states you are not protected by the price cap if you have a business energy contract. The Domestic Gas & Electricity (Tariff Cap) Act 2018 frames the cap around domestic consumers.
• Home cap for context only: from 1 October to 31 December 2026 the typical dual-fuel Direct Debit household benchmark is £1,723 a year (Ofgem). That is not your commercial unit rate.
• What SMEs get instead: fixed or variable commercial contracts, plus — if you qualify as a microbusiness — clearer principal terms, renewal price information, limited evergreen notice rules, broker redress routes, and Energy Ombudsman access for unresolved supplier complaints.
• Biggest practical risk: rolling onto out-of-contract or deemed rates after a fixed term ends or when you move in without a contract. Those rates are usually higher than a negotiated fix.
• What to do: diary your contract end date, gather MPAN/MPRN and kWh, and compare commercial quotes before the window closes — not via a household comparison journey.

Does the Ofgem price cap apply to business energy?

Ofgem’s own explainer is unambiguous: the price cap protects people on household standard variable / default tariffs. You are not protected by the price cap if you agreed a fixed household tariff, have a business energy contract, or take heat from a heat network or heating oil.

That matches how suppliers describe the commercial market. EDF’s small-business energywise note (published 27 August 2026) stresses that while the October domestic rise was about households, business energy contracts are not protected by a price cap, so reviewing tariff type and renewal timing matters more for SMEs than watching the household headline alone.

So when news sites say “the price cap is £1,723”, they are talking about a home typical-use bill. Using that figure as if it capped your non-domestic invoice is a common — and costly — myth.

Home working and mixed-use premises

If you run a business from home on a domestic supply, you are usually still on a household contract. Check with your supplier. Separate commercial premises almost always need a non-domestic contract. Do not assume the domestic cap “covers the business bit” of a mixed bill without confirmation in writing.

What the £1,723 home figure actually means (context only)

For 1 October to 31 December 2026, Ofgem set the domestic default-tariff cap so that a typical dual-fuel household paying by Direct Debit faces a £1,723 a year typical bill if those rates ran for a full year. That is about 4% higher than the July–September 2026 period. National average Direct Debit unit rates and standing charges published by Ofgem for that quarter are:

Fuel (home default tariff)	Unit rate	Standing charge
Electricity	26.32p/kWh	54.83p/day
Gas	7.97p/kWh	29.68p/day

Electricity figures in that Ofgem update exclude VAT for the temporary electricity VAT cut period; gas includes 5% VAT. None of these rates are a legal maximum for non-domestic contracts.

We mention them only so SME owners can separate the household headline from commercial pricing. Your business quote will use your site’s consumption shape, meter type, standing charge, Climate Change Levy treatment, credit risk and contract length.

What protects microbusinesses and SMEs instead

Who counts as a microbusiness

Ofgem’s business-contract guidance says you generally qualify as a microbusiness if you have fewer than 10 employees and annual turnover or balance sheet total of no more than £2 million, or if you use up to 100,000 kWh of electricity or 293,000 kWh of gas a year. Suppliers may use size or consumption when deciding which protections apply — ask them to confirm your status in writing.

Extra microbusiness protections (not a rate cap)

If you are a microbusiness, your supplier must typically:

• give clear information about the contract (including third-party / broker costs where relevant)
• limit termination notice periods to 30 days on evergreen contracts, and acknowledge end requests within 5 working days (evergreen)
• provide renewal price information before a fixed contract ends
• work with brokers signed up to a qualifying redress scheme when commission is paid via the supply

Microbusinesses and small businesses can get help from Citizens Advice, and unresolved supplier complaints can go to the Energy Ombudsman. Brokers paid by suppliers should be on an approved redress register — check before you sign. There is no cooling-off period after you agree a business energy contract, so read the schedule carefully.

These rights improve transparency and redress. They do not freeze your pence-per-kWh the way the domestic cap freezes default household unit rates and standing charges.

Home price cap vs business energy: side-by-side

Topic	Domestic (home) price cap	Business / non-domestic energy
Does a regulated rate cap apply?	Yes — for eligible default / SVT household tariffs	No — Ofgem: business energy contracts are outside the cap
Typical headline (Oct–Dec 2026)	About £1,723/yr dual fuel Direct Debit (typical use)	Site-specific commercial quotes; no equivalent national “cap bill”
What is limited?	Max unit rate + standing charge on capped default tariffs	Contract terms you negotiate (or deemed / out-of-contract defaults)
Microbusiness extras	N/A (domestic rules)	Clearer terms, renewal notices, broker ADR, Ombudsman routes
Biggest miss risk	Staying on SVT when a better fix exists	Missing renewal → out-of-contract or deemed rates

Out-of-contract and deemed rates: where bills jump

Ofgem explains the difference clearly:

• Deemed rates usually apply when you move into premises without arranging a formal contract, or sometimes if a supplier fails. They are typically higher than negotiated contracts.
• Out-of-contract rates can apply when a fixed-term deal ends and you have not agreed a new deal. Again, they are usually more expensive than a fresh fixed term.
• Rollover / evergreen arrangements may renew automatically — often for around 12 months and sometimes at a higher rate. Microbusiness rollover length is constrained (Ofgem notes microbusinesses cannot have a rollover for more than 12 months).

Because there is no domestic-style cap sitting underneath those defaults, comparing early is the main protection. See our deeper guides on out-of-contract business energy rates and deemed business electricity rates for the operational checklist.

Standing charges, VAT and other bill lines SMEs mix up with “the cap”

Commercial invoices often confuse owners who only follow household news:

• Standing charges on business meters can move sharply at renewal even when unit rates look familiar. Always compare total annual cost, not unit rate alone.
• VAT on business energy is usually 20%, with a possible 5% reduced rate if you meet the de minimis / qualifying use rules — that is separate from the domestic price cap. See VAT on business energy.
• Climate Change Levy may appear on electricity and gas for many businesses unless relief applies.
• Half-hourly metering, capacity and pass-throughs belong in larger-site quotes — not in the domestic cap story.

What EDF told small businesses about the October 2026 domestic rise

EDF’s Energywise article (27 August 2026) framed the Ofgem announcement as a 4% domestic rise from 1 October — about £60 a year on a typical household bill — driven largely by wholesale gas. It then made three points useful for SMEs:

1. Household bill pressure can cool consumer spending in retail and hospitality.
2. The same wholesale conditions that lift the home cap can feed into business renewal pricing.
3. Unlike domestic customers, business energy contracts aren’t protected by a price cap, so reviewing fixed vs variable options at renewal is the practical response.

We agree with that framing. Watching the domestic cap is still sensible for your home and as a rough signal of wholesale stress — it is not a substitute for a commercial quote pack.

Practical checklist before you renew or switch

1. Confirm contract end date and notice window — diarise 120 and 60 days out where possible (contract end date playbook).
2. Confirm microbusiness status with your supplier if you are near the employee / turnover / kWh thresholds (microbusiness rights).
3. Build one usage pack — MPAN/MPRN, 12 months kWh (or HH data), current rates, standing charge, VAT treatment, any deposit (security deposits).
4. Ask for broker commission in writing if you use an intermediary (broker fees).
5. Compare total cost across fixed length options — 1, 2 or 3 years — including standing charge and CCL, not just a headline unit rate (quotes guide).
6. Do not use a household comparison journey for a commercial meter. Start from SwitchSquid’s business form so your enquiry is treated as non-domestic.

Who this guide is for — and who should look elsewhere

Good for: sole traders, microbusinesses and SMEs on non-domestic electricity and/or gas who keep seeing “price cap £1,723” headlines and need a clear answer; owners approaching renewal; sites already on deemed or out-of-contract rates.

Not for: household dual-fuel switches on a domestic meter — use our separate home energy guides for that journey. This page never sends purchase CTAs to residential affiliate comparison.

Frequently asked questions

Is there a business energy price cap in the UK?

No. There is no Ofgem price cap that limits unit rates and standing charges on ordinary business energy contracts the way the domestic default-tariff cap does for eligible household customers. Commercial prices come from the contract you negotiate, or from deemed / out-of-contract defaults if you have not arranged a deal.

Does the £1,723 Ofgem figure apply to my shop or office?

No. Ofgem’s figure of about £1,723 a year for 1 October to 31 December 2026 is a typical domestic dual-fuel Direct Debit benchmark, useful for household headlines only. It is not a legal maximum for non-domestic invoices. Your business bill depends on your own kWh, standing charge, VAT, CCL and contract terms.

Do microbusinesses get any price protection?

Microbusinesses get process and transparency protections — clearer contract information, renewal price notices, limited evergreen notice rules, broker redress membership requirements, and Ombudsman routes — not a domestic-style rate cap. Confirm whether you qualify on employee, turnover/balance-sheet or consumption tests with your supplier.

What happens if my business fixed deal ends and I do nothing?

Many suppliers move you onto out-of-contract rates, which Ofgem notes are usually more expensive than negotiated contracts. Some arrangements may rollover. Either way, diary the end date and compare before you drift onto a default. Supply itself is not cut when you switch billing supplier later.

Are deemed rates the same as the price cap?

No. Deemed rates are a non-domestic default when you have no agreed contract (for example after a move-in). They are not the domestic price cap, and they are often higher than a properly quoted fixed term.

Can I use a home energy comparison site for my business meter?

You should not treat a household comparison journey as the path for a commercial MPAN/MPRN. Non-domestic quotes need business usage, credit and meter details. Use SwitchSquid’s business energy form at https://www.switchsquid.com/business-energy/ for commercial enquiries.

Will a rise in the domestic price cap automatically raise my business rates?

Not automatically on a live fixed commercial contract. Wholesale conditions that push the home cap up can still influence new business quotes and renewals, which is why EDF and others urge SMEs to review strategy when household headlines move. Check your own renewal letter rather than assuming a one-to-one uplift.

Where can I complain if my business supplier or broker will not resolve an issue?

Raise it with the supplier (and broker if involved) first. Micro and small businesses can seek help from Citizens Advice, and unresolved supplier complaints may go to the Energy Ombudsman. Brokers paid via supply commission should belong to a qualifying redress scheme — confirm which one before you escalate.
