British Gas is running a members-only flash sale offering 25% off their Homecare plans, making it the strongest deal for those with an existing membership. If you're not a member yet or looking for individual services rather than a full plan, the company also has a 20% discount on winter-ready Homecare packages and fixed-price boiler services available.
If you're a member looking at Homecare plans, take the 25% members' flash sale on Homecare until 8 September 2026—this is the best percentage saving available and applies across the full range of plans. This offer is only for members, so you'll need an existing British Gas account to benefit.
If you're not a member or prefer a simpler commitment, the 20% off winter-ready Homecare plans gives you a solid discount without the membership requirement. This runs until 8 September 2026 and is a good middle ground if you want to prepare your home for winter without the higher discount tier.
If you need a one-off or annual boiler service rather than a full Homecare plan, British Gas offers an annual boiler service for £109 per year or a one-off service at £119. These are fixed rates rather than discounts, so they work well if you simply want to book maintenance without taking out a broader plan. Both are subject to availability.
When you're ready to shop, only one offer will apply at checkout. If you're a member considering Homecare, compare the 25% saving against the 20% option to see which plan suits you best and calculate the final price—the flash sale should edge ahead. For anyone choosing between a Homecare plan and a standalone boiler service, work out whether the annual cost of a plan or the one-off service fee makes more sense for your home's needs.
