British Gas: The Fix v17 or stay on SVT? The July 2026 cap maths

If you do nothing, the British Gas Standard Variable Tariff (SVT) rises from £1,632/yr to £1,862/yr on 1 July 2026. 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.

The Fix Tariff v17 (£1,719/yr) is BG's only mainstream fix. It saves £131/yr versus the post-1-July cap — meaningful but the lowest fix-versus-cap saving of any Big Six supplier. The £150 dual-fuel exit fee is the largest in the market right now (E.ON £50, EDF £25–£75), so The Fix only makes sense if you're certain you'll stay 12 months. If a cheaper BG (or rival) tariff lands in autumn 2026, that £150 exit fee will eat much of the saving.

Compared with other Big Six fixes: E.ON Next Fixed v53 (£1,602/yr) is £117/yr cheaper than BG The Fix, with only a £50 dual-fuel exit fee. EDF Essentials Plus 12M (£1,649/yr) is £70/yr cheaper than BG The Fix, with zero dual-fuel exit on DD. For most households, switching from BG to E.ON or EDF makes more financial sense than re-fixing with BG — unless you specifically value BG's HomeCare boiler-servicing bundle or Hive smart-thermostat integration.

BG SVT (variable): only worth staying on if you're moving home in the next few months, expecting a sharp cap drop in October 2026, or planning to take part in the Free Electricity Sundays summer 2026 pilot (smart-meter SVT customers only).

British Gas Electric Driver v3 — 8.95p EV tariff

British Gas Electric Driver v3 drops electricity to 8.95p/kWh between 00:00 and 05:00 daily — a five-hour window with no exit fee. Daytime peak rates sit at standard cap-aligned levels (~27–28p/kWh in June 2026). The 8.95p rate applies to all household electricity used inside the window, not just EV charging — so dishwashers and washing machines on overnight delay also benefit.

For a typical 10,000-mile/yr EV driver (consuming ~3,000 kWh/yr in vehicle electricity) Electric Driver v3 saves around £550/yr versus charging at the standard variable cap rate. The tariff works with any home charger — dumb timer-based or smart — provided you have a SMETS2 smart meter in half-hourly settlement mode.

Worth comparing: E.ON Next Drive (6.7p over a seven-hour 00:00–07:00 window) and Intelligent Octopus Go (7p over a six-hour smart-controlled window with automatic extension). Both undercut BG Electric Driver v3 on headline off-peak rate. BG's advantage: pairs naturally with existing BG dual-fuel accounts and HomeCare. Compare at your postcode in the form above.

BG Heat Pump Tariff — 14.5p flat-rate dedicated tariff

British Gas Heat Pump Tariff charges 14.5p/kWh single-rate for all electricity used by households with a verified MCS-installed air-source or ground-source heat pump — well below the standard cap rate (~25–28p/kWh in June 2026). Eligibility requires proof of MCS installation; BG typically asks for the installer's MCS certificate and pump model. Once approved, the 14.5p rate applies to all your electricity, not just the pump.

For a typical 3-bedroom semi running an 8 kW heat pump with ~5,500 kWh annual electricity demand, Heat Pump Tariff at 14.5p saves around £680/yr versus the cap-aligned variable. It's a flat rate — no need to time-shift demand, so the pump can run on its native weather-compensation schedule.

Compare against: E.ON Next Heat Pump v2 (14p flat — fractionally cheaper). Octopus Cosy (13p in three windows 04–07, 13–16, 22–00) can be cheaper if your pump can shift demand into those nine hours but more complex to optimise. EDF doesn't currently offer a dedicated heat-pump tariff. Use the comparison form to model all three at your postcode.

BG Free Electricity Sundays — summer 2026 pilot explained

British Gas's summer 2026 pilot offers free electricity every Sunday from 1pm to 4pm for SVT customers with a SMETS2 smart meter. The three-hour Sunday window targets times of high solar output and low demand, helping balance the grid. Standard cap-aligned rates apply at all other times.

For a household that can shift dishwashers, laundry, EV charging or heat-pump pre-heat into the Sunday 1–4pm window, the saving can be meaningful — roughly 12 kWh saved per Sunday equates to about £3.30/week at current cap rates, or ~£40 over a 12-week summer pilot. Households that can't shift demand to Sunday afternoons see no benefit.

Eligibility: existing British Gas SVT customers with a SMETS2 smart meter in half-hourly settlement mode. New BG customers can switch to SVT and opt into the pilot via the British Gas app. The pilot runs over summer 2026 and is expected to extend or evolve based on uptake — BG has not yet confirmed a permanent product launch. Compare your overall BG cost-of-supply against the cheaper Big Six fixes (E.ON £1,602, EDF £1,649) via the form above to make sure the Sunday saving isn't being outweighed by a higher overall annual cost.

2. Compare like-for-like. Check unit rate, standing charge, annual TDCV, exit fee and contract length. BG The Fix v17 carries a £150 dual-fuel exit fee — the highest in the market. SVT, Electric Driver v3, Heat Pump Tariff, Multi-rate and Export & Earn Plus are zero-exit-fee.
3. Confirm your choice. Confirmation and welcome pack arrive within 5 working days.
4. 21-day cooling-off period. Cancel free of charge within 21 days under Ofgem's switching rules.
5. 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 BG The Fix v17 mid-contract, that £150 dual-fuel exit fee applies — factor it into the projected saving. For most BG 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 (June 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: tariff prices on The Fix v17 are uncompetitive versus E.ON and EDF; the £150 dual-fuel exit fee is unusually high.
