How the British Gas referral program works
British Gas pays per fuel switched: £25 each if the friend moves one of gas or electricity, £50 each for both, paid as Amazon.co.uk gift cards rather than bill credit. A separate track under the same scheme pays £100 for referring a boiler installation. There is no stated limit on referrals, and rewards claw back if the friend cancels within 90 days.
What the program pays
What makes this program different
A reward laddered per fuel. Switch both and the incentive doubles, precisely when the customer is worth double, without a separate dual-fuel offer. The stranger choice is the currency. An energy supplier pays in Amazon gift cards, not its own bill credit, which makes the reward feel like money but costs British Gas its face value with none of it returning as bill payment.
Why it works
Pricing per fuel scales the payout to the value of the switch with one simple rule.
A 90-day cancellation clawback aligns the reward with completed switches, not signatures.
A three-month cooling-off exclusion stops recently departed customers being re-referred for a bonus.
Extending the same scheme to boiler installations reuses one mechanic across products with very different order values.
What to copy
- Scale the reward by units of value switched rather than inventing tiers.
- Give the reward a claw-back window matched to your own cancellation terms.
- Exclude customers who left recently; a returning switcher is not an acquisition.
- The standalone terms PDF linked from the offer pages was dead on the date verified, so the on-page terms are the source here. An offer end date circulating in search results could not be verified on the page and is not recorded.
British Gas referrals, answered
How much is the British Gas refer-a-friend reward?
£50 each in Amazon.co.uk gift cards when the friend switches both gas and electricity, or £25 each for a single fuel. The boiler track pays £100 each, as Amazon, PayPal or a £50 Hive voucher.
When do British Gas referral gift cards arrive?
By email, up to three months after the friend joins, and only once the friend has passed the 90-day cancellation window that would cancel both rewards.
Who can be referred to British Gas?
Someone who has not held a British Gas energy contract within the last three months of joining. The referrer must verify as an existing customer through their online account.
