Skip to content Compare & Save on Business Energy
As a business owner, it’s essential to keep your overheads low, and one way to do this is to switch your business energy supplier to a more affordable one. We help you compare business energy prices using our business energy comparison tool to find a deal that works for your business needs and budget. Here are some reasons why you should switch your business energy supplier:
Business energy is the term used to describe the gas and electricity supply to non-domestic properties such as offices, shops, factories, and warehouses. It includes both the energy used by businesses for heating, lighting, and powering equipment, as well as the supply and distribution infrastructure required to deliver that energy.
When you compare business energy suppliers, there are several factors to consider. Here are some of the key things to keep in mind:
Suppliers offer a range of business energy tariffs to suit your business needs. Here are some of the different types of tariffs :
With a fixed-rate tariff, you pay a set price for your energy for a set period. This can help you budget more effectively and avoid price hikes.
Green energy tariffs are becoming increasingly popular, and they allow you to use renewable energy sources for your business energy needs. This can help you reduce your carbon footprint and support sustainable energy production.
With a variable rate tariff, your energy prices can go up or down depending on the market. This can be a good option if you want flexibility and don’t mind price fluctuations.
Switching business energy suppliers with us is simple. Here’s how it works:
By switching to a new business energy supplier, you can save money, get better service, and reduce your carbon footprint. Get in touch with us today to start comparing business energy prices.
Here’s a concise step‑by‑step guide to switching business energy suppliers with our partner:
Get a personalised quote – Start by entering your business postcode (or address) into our comparison tool. The system finds your meter details and typical usage to generate a list of quotes from multiple suppliers.
Gather your information – To ensure accurate pricing, have your Meter Point Reference Number (MPRN) for gas and Meter Point Administration Number (MPAN) for electricity ready, along with your business address, desired contract start date and an estimate of your annual consumption. This information is usually on your latest bill.
Compare and choose a deal – Review the available tariffs and pick the one that fits your needs. You’re free to stay with your current supplier if they offer a competitive deal. Both fixed‑rate and variable‑rate tariffs are available, and large users may need specialised meters.
Complete the switch – After you’ve selected a tariff, our partner manages the entire switching process on your behalf. They liaise with the old and new suppliers and keep you updated at each stage. Your energy supply is not interrupted; only the company billing you changes.
Time it right – Plan your switch during the contract’s renewal window—typically one to six months before the end date—to avoid being rolled over onto expensive “out‑of‑contract” rates. If you move premises, the previous tenant’s supplier will keep supplying you at high out‑of‑contract rates until you arrange a new deal.
Separate gas and electricity – Dual‑fuel tariffs are for households only. Businesses must switch gas and electricity separately, though you can still use the same supplier for both fuels by signing separate contracts
Be aware of credit‑score effects – Your company’s credit score may influence which suppliers and tariffs are available, and a lower score could mean higher deposits or additional conditions
Following these steps helps you find the most cost‑effective energy tariff for your business with minimal hassle.

No, your business energy supply should not be affected if you switch suppliers. This is because the gas and electricity infrastructure and the meter at your property are owned and maintained by the local distribution network, not your energy supplier. The only change you should notice is a different supplier name on your bills, and potentially lower energy costs.
If you have multiple business premises, you can choose to have a separate energy contract for each site or a consolidated contract that covers all your properties. The choice will depend on your business needs and energy usage patterns. A consolidated contract may offer benefits such as lower tariffs and simplified billing.
A Letter of Authority (LOA) is a document that authorizes a third party, such as a broker or consultant, to act on behalf of your business when dealing with energy suppliers. It allows the third party to access your energy account information, negotiate tariffs and contracts, and make changes to your energy supply arrangements. An LOA is required for brokers and consultants to provide energy procurement services to your business.
The main difference between domestic and business energy is the way it is priced and billed. Business energy tariffs are usually more complex and offer different pricing structures, depending on the size and usage of the business. Domestic energy tariffs are simpler and usually charge a fixed rate for the energy used. Business energy tariffs may also include additional charges such as standing charges, capacity charges, and distribution charges.
Yes, some business energy tariffs do offer a dual fuel option, which means that you can have both your gas and electricity supplied by the same energy supplier. This can simplify your billing and administration and may also offer cost savings. However, not all energy suppliers offer dual fuel tariffs for businesses, so it’s important to check with your supplier or broker to see if it’s an option for you.
You can find your MPAN (for electricity) or MPRN (for gas) on your current business energy bill. It’s usually a 13-digit number for MPAN, and a 10-digit number for MPRN. You’ll need this to get accurate quotes and to switch suppliers smoothly.
The best time to switch is during your contract’s renewal window—often 1 to 6 months before the contract ends. If you switch earlier or after the renewal date, you may incur early-termination fees or be forced onto an out-of-contract rate, which is usually more expensive.
You’ll typically need your latest energy bill (to get meter details like MPAN/MPRN), proof of your business address (e.g. business rates, lease, or utility bills), business name and legal registration number, and an estimate of your annual usage. Having all this ready speeds up the switch.
Yes. Many business energy contracts are based on usage bands. If your consumption falls below or rises above the band you signed up for, your rates (or standing charges) may be adjusted. Some meters are half-hourly, meaning suppliers track usage more precisely and charge accordingly.
Not always. Green or renewable business energy tariffs sometimes cost a little more upfront, but many now offer competitive or even lower prices when factoring in government incentives, supplier offers, and long-term savings. Always compare the total cost, including any green premium and whether the supplier guarantees renewable supply.
Toggle CoNo. Renewal is the usual time to look, because you can avoid out-of-contract rates and early-termination fees. It is still worth asking your current supplier for a retention price and comparing the whole contract — length, standing charges and fees — not only the unit rate. Staying can be the better commercial choice.ntent
Toggle CoOnly if the supply is genuinely non-domestic. A household meter used mainly as a home remains a domestic supply and should be compared as household energy. Using the wrong class of tariff can create billing and tax problems. If you are unsure, check how the meter is registered and compare on the matching page.ntent
These historical figures are included only as an illustration. They are not current market prices and must not be used to budget or compare a live contract.
Answer: This page is for organisations in Great Britain that pay non-domestic electricity and/or gas bills — offices, shops, hospitality, warehouses, workshops, clinics, charities and similar sites — and want to compare commercial contracts, not household tariffs.
Use it if you have a business meter, a company, partnership, sole-trader or charity account, one site or several, and you can find an MPAN (electricity) and/or MPRN (gas) on a bill. Microbusinesses and larger users can both start here; half-hourly and multi-site portfolios may need extra paperwork.
Do not use this for a home energy bill. Domestic gas and electricity — including a home office on a household meter — is a different market with different rules, VAT and the Ofgem price cap. Compare those on compare gas and electricity. The domestic energy price cap does not set business prices.
Business switching is still a change of who bills you, not of the wires and pipes. Supply should not be interrupted. Unlike most household switches, there is typically no 14-day consumer cooling-off period, contracts are longer, and leaving early can trigger termination fees. Time the process to your renewal window. For the household process (different rules), see how to switch energy supplier.
| Household energy | Business energy |
|---|---|
| Ofgem default-tariff price cap can apply | No domestic price cap — commercial prices are negotiated |
| Often dual-fuel on one switch | Usually two contracts (gas and electricity), even with one supplier |
| Typical home switch around 21 days; 14-day cooling-off on most tariffs | Timing depends on contract, credit checks and paperwork; cooling-off is not the household model |
| VAT on domestic energy at the reduced rate (and a temporary electricity VAT change in 2026/27 — see the price cap hub) | VAT is usually at the standard rate; many businesses can reclaim it. Climate Change Levy may apply |
| You compare and apply yourself | You may compare yourself or authorise a third party via an LOA |
Your company’s credit standing can affect which suppliers quote and whether a deposit is required. Large or half-hourly sites may need interval data, not just an annual kWh estimate.
Business comparison through EnergySwitch is free for your organisation to use. As with other UK comparison and brokerage routes, EnergySwitch may earn a commission or affiliate fee from a supplier or partner if you take a contract or complete a switch through this site. That is how the service is funded. It is not an extra line on your energy invoice from us.
We compare independently. Rankings and recommendations are based on published methodology, not paid placement. Commission does not entitle a supplier to a higher position. You remain free to decline every quote, renew with your current supplier, or go direct.
If anyone asks you to sign a Letter of Authority, treat it as a legal appointment. An LOA can let a third party see your account data, request quotes, and — if the wording allows — switch your supply. Only sign if you understand the scope, the end date, and how that party is paid. You do not have to appoint a broker to compare or to switch. For affiliate-link wording, see our terms of use.
Figures below are made up to show the arithmetic. They are not live business rates, not an average, and not a saving you should expect. Business prices vary by region, meter, credit, contract length and wholesale conditions. Always use a real quote.
A high-street shop uses 12,000 kWh of electricity a year and has rolled off a fix onto out-of-contract rates. Ignore VAT (often reclaimable) and Climate Change Levy for this sketch so the method is visible.
| Illustrative out-of-contract | Illustrative 24-month quote | |
|---|---|---|
| Unit rate | 32.0p/kWh | 27.0p/kWh |
| Standing charge | 80p/day | 90p/day |
| Energy (12,000 kWh) | £3,840 | £3,240 |
| Standing charges (365 days) | £292 | £328.50 |
| Illustrative annual total | £4,132 | £3,568.50 |
On those invented numbers the quote is about £560 a year lower. That gap only counts if:
If the same shop still had four months left on a fix, you would add any early-termination fee and compare that total with the cost of sitting tight until the renewal window. Sometimes the current supplier’s retention price wins. Run your own business comparison rather than scaling this example.
Household cheap deals lists and the Ofgem typical-bill figures (£1,663 / £1,723) are not business prices. Do not use them to budget a commercial site. If you also want to cut use — not just the rate — some of the practical ideas on energy saving advice (LEDs, heating controls, draughts) still apply to small premises, but the tariffs and schemes are different.
Compare business electricity and gas with your MPAN/MPRN and usage, and keep household switching on the domestic journey.
These questions add to the FAQs already on this page (supply interruption, multi-site, LOA, MPAN/MPRN, renewal windows and documents). They do not replace them.
No. The Ofgem energy price cap limits default domestic tariffs in Great Britain. It does not set prices for shops, offices or other non-domestic supplies. Budget from a business quote, not from the household typical-bill figures.
The comparison is free for your business. EnergySwitch may earn a commission or affiliate fee from a supplier or partner if you take a contract through this site. Rankings are based on published methodology, not paid placement. You can decline quotes, renew where you are, or go direct.
No. Renewal is the usual time to look, because you can avoid out-of-contract rates and early-termination fees. It is still worth asking your current supplier for a retention price and comparing the whole contract — length, standing charges and fees — not only the unit rate. Staying can be the better commercial choice.
Only if the supply is genuinely non-domestic. A household meter used mainly as a home remains a domestic supply and should be compared as household energy. Using the wrong class of tariff can create billing and tax problems. If you are unsure, check how the meter is registered and compare on the matching page.
