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.

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.
As British Gas's own pages put it, in our words:
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.
Three household export tariffs, all variable with no exit fee: Export Premium and Export Extra for British Gas electricity customers, split at 15kW, and Export SEG for everyone else

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.
Mandatory SEG licensees: British Gas Trading Limited; E (Gas and Electricity) Ltd; E.ON Next Energy Limited; EDF Energy Customers Limited; Electricity Plus Supply Limited (trading as Utility Warehouse); Foxglove Energy Supply Limited; Fuse Energy Supply Limited; Octopus Energy Limited; OVO Electricity Ltd; ScottishPower Energy Retail Limited; So Energy Trading Limited; Utilita Energy Limited. Voluntary: Pozitive Energy Ltd; Ruby Electricity Ltd; Smart Pay Energy Ltd; Voltx Power Ltd

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.
You can use one company for export payments and another for your electricity supply

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.
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.
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.
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.
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.
