Shell Energy business: a neutral guide

What changed with Shell Energy

Shell's UK energy history causes confusion because household and business supply were separate. Shell announced in 2023 that it was selling its home energy businesses, Shell Energy Retail Limited in the UK and Shell Energy Retail GmbH in Germany, to Octopus Energy Group. Shell announced the sale was complete later in 2023.

The home supplier is therefore no longer Shell's. Business supply was not part of that deal: an S&P Global report on the September 2023 announcement said Shell's SME supply business was unaffected, and Shell continues to publish business energy pages, including a business complaints page, on its own UK website. We could not confirm from Shell's site which Shell company holds each business contract, so read the name on your own bill.

Step one: work out exactly who supplies you

If you have an account with anything called Shell Energy, look at the top of your most recent bill or your contract's Principal Terms and note:

• The legal company name and registered address.
• The meter point numbers (MPAN and MPRN), so you know which sites are covered. See how to find them.
• The contract start and end dates.

The legal name tells you who owns the contract, who to complain to and which Ombudsman rules apply. If the name is unfamiliar, search for it on Companies House.

What kinds of business does it serve?

We could not verify Shell Energy's current minimum or maximum customer size from its own site, so we will not put a number on it. The better test is practical: ask for a quote and see whether you are offered a standard small-business contract with a published unit rate and standing charge, or a bespoke commercial quote. Your answer says a lot about whether the supplier treats customers of your size as its core market.

Cost illustration: why standing charges matter

Whichever supplier you look at, check the whole annual cost. Imagine two quotes for a small office using 15,000 kWh of electricity a year, using invented rates:

Quote	Unit rate	Standing charge	Annual cost
A	26p/kWh	70p/day	£3,900 + £255.50 = £4,155.50
B	24p/kWh	150p/day	£3,600 + £547.50 = £4,147.50

(15,000 × 0.26 = £3,900; 365 × 0.70 = £255.50; 15,000 × 0.24 = £3,600; 365 × 1.50 = £547.50.) The "cheaper" unit rate gains nothing once the standing charge is counted. Use our business energy cost calculator to do this properly, and read business energy standing charges.

Contacting Shell Energy and complaints

Shell publishes a dedicated business customers complaints page. Follow the steps it sets out; the general pattern for any supplier is:

1. Complain in writing, with account number, dates and what you want done.
2. Ask for a reference number and the supplier's response time.
3. If you cannot agree, ask for a deadlock letter.
4. If you are a microbusiness or small business, go to the Energy Ombudsman after 8 weeks or on receipt of the deadlock letter, within 12 months of that letter.

Citizens Advice can help microbusinesses with energy problems. See energy disputes and the Ombudsman.

Renewal and out-of-contract rates

Whoever your supplier is, the renewal rules are the same. Microbusiness rollovers can last no longer than 12 months. A supplier must give proper renewal information first, and if you are out of contract it cannot charge a termination fee. Out-of-contract rates tend to be higher. An indicative Moneysupermarket Business page from 21 October 2026 put average out-of-contract electricity at 40.0p/kWh plus 254.0p/day, against 28.4p/kWh plus 58.0p/day for an average microbusiness fixed deal. For a micro site using 20,000 kWh, the difference is:

• Out of contract: 20,000 × 0.40 = £8,000, plus 365 × 2.54 = £927.10, total £8,927.10.
• Fixed average: 20,000 × 0.284 = £5,680, plus 365 × 0.58 = £211.70, total £5,891.70.
• Gap: £3,035.40 a year.

These are published averages from a comparison site, not offers. Details are in how much more deemed rates cost.

Checking a business bill line by line

Whichever Shell company or other supplier bills you, the same checks catch most errors:

1. Is each reading marked actual or estimated? If estimated, send a dated meter photo and ask for a revised bill.
2. Do the unit rate and daily standing charge match the Principal Terms you signed?
3. Is the Climate Change Levy charged at 0.801p/kWh for usage from 1 April 2026, unless you are exempt?
4. Is VAT charged at 20% for normal business use, or at a reduced rate you have shown you qualify for?
5. Does the billing period overlap with, or leave a gap after, the previous bill?

If something is wrong, raise it in writing with the bill reference. Paying the undisputed part while the query is resolved helps avoid debt that could later block a switch.

Questions to ask before renewing

• Which legal company will supply me, and is it the same one named on my current contract?
• Are the unit rate and standing charge fixed for the whole term, or can network costs be passed through?
• Is a broker involved, and what is the broker cost in pounds for the full term?
• What is the last date to give notice, and how should notice be sent?
• If I move premises during the term, can the contract move with me, and is there an exit fee if not?

Get the answers by email so you have a record. There is no cooling-off period on business energy contracts, so agree nothing until you have the written terms.

How to switch away

Ofgem says variable, out-of-contract and deemed contracts can be left at any time. Fixed contracts usually run to the end date, with a switching window in the months before. Settle any debt first because a supplier may object. See how to switch business energy supplier.

Next steps

• Identify your legal supplier and contract end date today.
• Compare the full annual cost of at least two quotes.
• Browse UK business energy suppliers for alternatives.
