Available tariffs from British Gas
British Gas: fix now or stay on SVT? The July 2026 cap maths
If you do nothing, the British Gas Standard Variable Tariff (SVT) is £1,663/yr. The cap jump is driven mostly by wholesale gas: +24% on gas unit rates, +5% on electricity. The October 2026 cap is announced by Ofgem in late August; analysts including Cornwall Insight currently forecast roughly £1,712/yr for October (analyst forecast, so treat it as indicative).
Fixing with British Gas: the current range spans 12 to 24 months — Samsung Weekend Saver Fix (12-month), Fixed Tariff Sep27 (14–15 month) and Exclusive Fixed Aug27 (14-month), plus the 24-month Fix and Fall Jul28/Jun28 deals, where your price can fall at subsequent cap reviews but won't rise. Fixed deals across the market are typically priced a few per cent below the cap; exact pricing and any exit fees vary by region and tariff version, so check the tariff information label and get a postcode-level quote before committing.
Compared with other suppliers: other large suppliers also offer fixes priced below the cap, and the cheapest deal at your postcode may not be a British Gas one. Use the comparison form to stack BG's live price against the wider market — unless you specifically value BG's HomeCare boiler-servicing bundle or Hive smart-thermostat integration, in which case the bundle may justify paying slightly more.
BG SVT (variable): only worth staying on if you're moving home in the next few months, hoping for a lower cap at the October 2026 review, or taking part in British Gas's PeakSave demand-flexibility scheme (including its free electricity Sundays sessions for smart-meter customers).
British Gas EV tariffs — what to check in August 2026
EV tariffs work by offering a cheap overnight off-peak window for home charging, with standard rates during the day. Suppliers refresh EV tariff versions and rates frequently, and no British Gas EV tariff appears in our live tariff feed as of 8 July 2026 — so we don't publish a rate for one here. Check British Gas directly for its current EV offer.
What to compare on any EV tariff: the off-peak rate, the length and timing of the cheap window, whether the discounted rate applies to the whole household's electricity or just the charger, exit fees, and smart-meter requirements (most need a SMETS2 meter in half-hourly settlement mode).
Several suppliers offer competing EV tariffs with different windows and rates. Compare what's live at your postcode in the form above.
British Gas and heat-pump tariffs — August 2026
Dedicated heat-pump tariffs offer discounted electricity to households with an MCS-installed air-source or ground-source heat pump, usually on proof of the installer's MCS certificate. Availability and rates change often, and no British Gas heat-pump tariff appears in our live feed as of 8 July 2026 — check British Gas directly for its current offer and eligibility requirements.
If you run a heat pump, compare flat-rate heat-pump tariffs against time-of-use deals: a flat rate needs no demand-shifting, while windowed tariffs can work out cheaper if your pump can pre-heat within the cheap windows. Use the comparison form to model the live options at your postcode.
British Gas PeakSave — free electricity Sundays explained
PeakSave is British Gas's demand-flexibility scheme, and its best-known strand is free electricity Sundays — sessions in which participating smart-meter customers pay nothing for the electricity they use inside a set Sunday window. British Gas sets the session timing and eligibility rules, and details change between rounds, so check the British Gas app or website for the current schedule before relying on it.
Households that can shift dishwashers, laundry, EV charging or heat-pump pre-heat into the free sessions benefit most; if you can't move usage into the window you'll see little difference. PeakSave is a bolt-on saving, not a tariff — make sure your underlying tariff is competitive first via the form above.
How to switch to or away from British Gas — 5 steps
- Get a quote on this page. Use the comparison form with your postcode and rough annual kWh — we return BG's live deal plus the cheapest comparable fix across the market.
- Compare like-for-like. Check unit rate, standing charge, annual TDCV, exit fee and contract length. Exit fees vary by tariff and version — check the tariff information label before signing up. Variable tariffs (SVT and Safeguard) carry no exit fees.
- Confirm your choice. Confirmation and welcome pack arrive within 5 working days.
- 14-day cooling-off period. Cancel free of charge within 14 days under Ofgem's switching rules.
- Switch completes in 5 working days. Meter reading request, automatic supply transfer, no break in service — protected by the Energy Switch Guarantee.
If you're switching from a British Gas fixed deal mid-contract, check the tariff information label for any exit fee and factor it into the projected saving. For many fixed customers, waiting until the fix ends (then re-quoting) is the better strategy.
British Gas reputation — Citizens Advice, Trustpilot, customer service
British Gas has consistently sat at the lower end of Citizens Advice's quarterly star rating for the Big Six — typically 2.5 to 3 stars out of 5 over the last four quarters of 2025/26. The main pain points reported: long call-waiting times during winter, complaint-resolution speed, and bill-correction delays after meter readings. BG has invested heavily in its app and online account portal in 2025 to mitigate the call-centre bottleneck, with mixed reviews.
Trustpilot (August 2026): around 4 stars (Great) across ~150,000 reviews — competitive on the platform but skewing higher on HomeCare boiler-servicing feedback than energy supply. BG's largest strengths versus other Big Six suppliers: the HomeCare boiler-servicing product (no other Big Six supplier matches it), Hive smart-thermostat integration, and brand recognition. Largest weakness reported by switchers: BG's fixed deals aren't always the cheapest at a given postcode — always compare before signing or renewing.
Frequently asked questions — British Gas tariffs (August 2026)
What's the cheapest British Gas tariff in August 2026?
Our live feed (8 August 2026) lists British Gas's fixed range as Fixed Tariff Sep27 (14–15 month fixes), the 24-month Fix and Fall Jul28/Jun28 deals, Exclusive Fixed Aug27 and the 12-month Samsung Weekend Saver Fix. The feed carries names and contract lengths only — prices vary by region and usage, and fixed deals across the market are typically priced a few per cent below the £1,663 cap. Check the live price for your postcode via the comparison form.
When does British Gas SVT change price?
BG SVT tracks the Ofgem default tariff cap. The cap last changed on 1 July 2026 and is £1,663/yr. The October 2026 cap is announced in late August 2026 (analysts including Cornwall Insight forecast roughly £1,712/yr, current-TDCV basis). A fixed British Gas deal is locked at its agreed price for the full contract regardless of cap movement.
Do British Gas fixed tariffs have exit fees?
Exit fees vary by tariff and version, and our live feed doesn't carry exit-fee data — check the tariff information label for the specific deal before signing up. As a rule, variable tariffs (SVT and Safeguard) carry no exit fees, while fixed deals may; if a fix does carry one, only sign up if you're confident you'll stay the full term.
Does British Gas offer an EV tariff?
EV tariffs change frequently and no British Gas EV tariff appears in our live feed as of 8 July 2026, so we don't publish EV rates here — check British Gas directly for its current offer. When comparing any EV tariff, look at the off-peak rate, the window length and timing, exit fees and smart-meter requirements, then compare what's live at your postcode in the form above.
Who qualifies for free electricity Sundays (PeakSave)?
PeakSave is British Gas's demand-flexibility scheme, and free electricity Sundays is its best-known strand, open to participating British Gas smart-meter customers. Session timing and eligibility rules change between rounds — check the British Gas app or website for the current schedule.
Does British Gas have a dedicated heat-pump tariff?
No British Gas heat-pump tariff appears in our live feed as of 8 July 2026. Dedicated heat-pump tariffs typically require proof of an MCS-installed air-source or ground-source heat pump, and availability and rates change often — check British Gas directly, then compare the live options at your postcode via the comparison form.
What solar export (SEG) options does British Gas offer?
Smart Export Guarantee rates are set by each supplier and change regularly, and our live feed doesn't carry British Gas export rates — check British Gas's SEG page directly for the current offer. When comparing SEG deals, look at the export rate, whether you must take the supplier's import tariff to qualify, and how it stacks against other SEG providers.
Will energy prices fall again later in 2026 — should I fix now?
Not guaranteed. The next Ofgem review takes effect on 1 October 2026 and analysts including Cornwall Insight currently forecast roughly £1,712/yr — broadly flat rather than a sharp fall. Because the July rise is driven mostly by wholesale gas (+24% gas vs +5% electricity), a fixed deal below the £1,663 cap removes that uncertainty. About 40% of accounts on fixed tariffs were unaffected by the July rise. If you value certainty, fixing now on a deal that beats the cap is reasonable; if you expect to move home soon, staying on SVT keeps you flexible.
How long does a British Gas switch take?
Five working days under the Energy Switch Guarantee, plus a 14-day cooling-off period during which you can cancel free of charge. The supply transfers automatically; no break in service. See the step-by-step guide above.
Compare British Gas under the current price cap
The Ofgem cap is £1,663/yr. Only Standard Variable customers are affected — fixed deals are protected, and fixes across the market are typically priced a few per cent below the cap. British Gas's live range includes the Fixed Tariff Sep27 fixes, the 24-month Fix and Fall deals, Exclusive Fixed Aug27 and the Samsung Weekend Saver Fix. Compare at your postcode in 60 seconds.
