British Gas SEG export tariff — Export & Earn Plus, June 2026

Is 15.1p actually good?

Export & Earn Plus sits in the bottom half of the SEG market. Of roughly 30 live SEG tariffs (June 2026), the strongest flat rates — Good Energy's Solar Savings Exclusive at 25p and EDF's Export Exclusive 12m V2 at 24p — pay over 60% more per unit, and E.ON Next's 16.5p edges it too. The trade-off: those exclusives require moving your electricity import too — exactly the friction British Gas is counting on.

Import and export suppliers can be different under SEG rules, so you have room to manoeuvre. Check the full table on our best SEG export rates guide, and price a whole-package move with a free quote — with the cap rising 1 July 2026, the import side matters too.

Our honest verdict: convenient, not competitive

On a 4kW system exporting ~2,400 kWh a year, 15.1p pays an estimated £362. The same export earns £600 at Good Energy's 25p and £576 at EDF's 24p — staying put leaves roughly £238 a year on the table, about £20 a month. Still, it's nearly double Ecotricity's 8.9p and triple the 5p legacy floor. See how it fits alongside import deals on our British Gas tariffs page.

Who it genuinely suits

BG loyalists who want one bill and no switching admin. Low exporters — self-consume most generation and the pence gap is worth tens of pounds, not hundreds. Households mid-contract on a BG fix, where exit fees could eat the gain. Exporting 2,000+ kWh a year? The numbers point to an upgrade. More: our British Gas profile.

British Gas dual fuel

The catch most people miss: both gas and electricity must be with British Gas. Electricity-only customers don't qualify.

MCS-certified installation

Your solar PV system needs an MCS certificate (standard for professional installs) — it's the first thing any SEG application asks for.

Smart meter

A SMETS2 smart meter (or DCC-migrated SMETS1) recording half-hourly export is mandatory. No working smart meter, no SEG payments.

How to sign up — or upgrade away

1. Gather your details: MCS certificate number, panel kW, battery capacity, MPAN, export reading.
2. Check your import position: confirm you're BG dual-fuel — or weigh moving import for 25p/24p.
3. Apply: registration takes 5–10 working days.
4. Cancel any old SEG deal with 14 days' written notice.
5. Take a reading on switchover day and check your first statement.

The two upgrade paths

Path 1 — keep BG import, export elsewhere. Stay with BG and take an open-market export deal such as Ecotricity at 8.9p. That's lower than 15.1p, so it only makes sense if you don't qualify for Export & Earn Plus (e.g. electricity-only customers).

Path 2 — move import for a top rate. The serious money requires bundling: switch your electricity import to Good Energy (25p) or EDF (24p, ≤5kW) and take their exclusive export tariff. Compare the whole package — a great export rate on a poor import deal can be a net loss.
