British Gas Smart Export Guarantee rates: Export Premium, Export Extra and Export SEG

What British Gas pays for the electricity your panels send back, who is allowed each rate, and how British Gas says you apply. Read from its own page, with how it compares to every other supplier we track. Nobody is going to ring you.

Figures on this page last checked 28 September 2026. Each carries its own receipt with its own date.

Rates as of 28 September 2026. Read from British Gas's own page (www.britishgas.co.uk/energy/smart-export-guarantee.html). If a rate here disagrees with British Gas's page today, British Gas's page wins.

British Gas has three export tariffs for homes: Export Premium for its electricity customers with systems up to 15kW, Export Extra for customers with bigger systems, and Export SEG for everyone else. All three are variable, with no exit fee and no end date. Its page carries the date it was last updated, which is rarer than it should be. It also prints its rates as £12p and £8p, which we have taken to mean pence.

How British Gas compares with every other supplier

We keep every supplier's export rates in one table, each read from that supplier's own page. Here is where British Gas's rates sit in it, group by group, because a rate only means something against the others you could actually have.

The ranks and the differences in pence are our comparison from the table as we last read it, not figures British Gas publishes. Rows paying the same rate share a place. Time-of-use and wholesale-linked tariffs anywhere in the table are left out of the ranking, because they have no single rate to rank. The rate open to anyone runs from 2p/kWh to 13p/kWh across the whole table.

What you need before you apply

As British Gas's own pages put it, in our words:

How to apply, as British Gas describes it

  1. Apply through British Gas's online form, which walks you through it step by step.
  2. British Gas emails to confirm it is working on the application, and asks if it needs anything more.
  3. Setting up the account can take up to 4 weeks. If you are new to SEG, British Gas creates and registers your export MPAN, the meter number for exported electricity. If you are moving from another provider, it gets the MPAN from them.
  4. Payment then comes every 3 months by bank transfer, within 28 days of British Gas receiving your export reading. With a working smart meter the reading usually sends itself.

You apply on British Gas's own site. We do not take applications, we do not ask for your details, and nobody pays us for sending you there.

Is British Gas obliged to offer this?

Ofgem lists British Gas Trading Limited as a mandatory SEG licensee for 1 April 2026 to 31 March 2027. Ofgem publishes which suppliers have told it they are taking part in the Smart Export Guarantee each year. The big ones have no choice: a supplier with enough household customers must offer a tariff. Smaller ones can volunteer.

Ofgem's rule is that your export payments, your electricity supply and your gas supply can each be with a different company. So you can take an open-to-anyone export tariff from one supplier and keep buying your electricity from another. The catch is in the table: the higher rates are mostly reserved for that supplier's own customers, so switching your export alone gets you the open tier.

Questions people actually ask

What is the British Gas SEG rate?

It depends whether British Gas supplies your electricity. Export Premium pays 12p/kWh to British Gas electricity customers with systems up to 15kW, and Export Extra pays 8p/kWh for systems over 15kW. Everyone else, and developers, get Export SEG at 3p/kWh. All three are variable.

Do I need to be a British Gas customer for the Smart Export Guarantee?

No. British Gas's page says you do not have to be an existing customer. Without British Gas supply you are on Export SEG at 3p/kWh. The higher Export Premium and Export Extra rates need British Gas to supply your electricity.

What is British Gas Export Premium?

British Gas's export tariff for its own electricity customers with systems up to 15kW, which covers almost any house roof. It pays 12p/kWh, is variable, and has no exit fee or end date.

How does British Gas pay for exported electricity?

Every 3 months, by bank transfer, within 28 days of receiving your export meter reading. With a smart meter the reading usually goes automatically; if British Gas cannot get it, it asks you for one every three months.

What happens to my British Gas export rate if I switch electricity supplier?

British Gas says it moves you automatically to its Export tariff from the date you change supplier, so you drop from the customer rate to 3p/kWh. It may ask for an export reading on the day, so it can pay what it owes at the higher rate up to then.
