British Gas informed wholesale brokers Monday it will not adjust standard variable tariffs before Ofgem publishes its October price-cap consultation, leaving about 2.4 million households on existing unit rates through at least mid-October while parent Centrica PLC waits for the regulator’s winter allowance and standing-charge assumptions, according to a tariff-hold notice circulated to trade desks and reviewed by InfoHandle. The decision is administrative, not a price cut: variable customers stay on July-era pence-per-kWh tables until Ofgem confirms the cap period that starts 1 January, and British Gas is not pre-announcing January bills.
What Centrica actually decided
Centrica’s retail board signed off a “no mid-window change” rule for British Gas SVR and default tariffs after Ofgem opened its autumn consultation on 15 September. Fixed-deal customers are unaffected—their contracts roll on agreed terms. The hold matters for SVR households who expected another supplier-style nudge when wholesale gas futures dipped briefly in late August; British Gas is keeping powder dry until Ofgem’s model inputs are public.
Internal planning slides seen by analysts put British Gas’s average dual-fuel SVR bill at roughly £1,720 a year on typical use—within a few pounds of the current cap, not a marketing number but the blend of unit rates and standing charges on file. Prepayment meter customers see the same unit rates with different debt-recovery rules; the hold memo explicitly says PPM tables mirror SVR until the cap resets.
How Ofgem’s October window works
Ofgem sets the cap using a basket of wholesale costs, network charges, and policy levies, then lets suppliers charge up to the cap—not necessarily at it. The October consultation typically previews January–March allowances; suppliers use it to decide whether to shave margins or launch fixed products. British Gas’s hold means no voluntary under-cap discount this side of Christmas, unlike some challengers that briefly undercut the cap to win switches in spring.
Standing charges remain the political sore point: British Gas did not promise to shift pounds from the daily fee into unit rates in this notice. Centrica executives told investors in August that standing-charge politics are “regulator-led,” which is code for waiting on Ofgem’s separate review rather than unilateral retail moves.
What households should verify
If you are on SVR, check your bill’s rate table against British Gas’s online tariff sheet dated July—not an old email quote. Direct debits based on estimated use may still need manual reads before winter; the hold does not pause meter submissions. Warm Home Discount eligibility runs on a separate timetable; this tariff notice does not change who qualifies.
Challenger suppliers may still move fixed offers; British Gas’s hold is not an industry freeze. Comparison sites will show mixed signals until Ofgem publishes final cap figures in November.
Investor and political read-through
Centrica shares barely moved on the hold because retail SVR margins are thin compared with North Sea production and services contracts. Analysts note British Gas’s brand still carries switching friction: households linger on SVR longer than econometric models predict, which stabilises cash flow even when headlines scream about bill shock. Labour MPs pressing for standing-charge cuts will not get ammunition from this notice; the company deferred to Ofgem rather than volunteering a retail restructuring.
Smart-meter rollout delays in parts of Scotland and Wales mean some British Gas SVR customers still receive estimated bills; the hold does not change meter booking queues. Field engineers prioritise faulty gas assets over elective smart upgrades—a separate operations backlog unrelated to tariff tables but relevant to winter accuracy.
What changes after consultation
Centrica can adjust SVR the day after Ofgem confirms January cap parameters, usually late November, unless it chooses an earlier competitive move on fixed products only. British Gas Energy Support Fund applications continue; the hold is not a moratorium on payment plans.
Fixed-rate shoppers should watch British Gas’s separate fixed tariff page; the SVR hold does not cap how aggressively the supplier prices one- or two-year locks to win switches. Broker channels said Centrica kept fixed margins unchanged Monday while SVR sat still—two levers, one announcement. If wholesale gas spikes before November, British Gas could raise fixed offers without touching SVR until the cap date, a pattern regulators allowed in prior cap cycles.
For Britain’s largest legacy supplier base, the actionable fact is dated: variable rates stay put through the October review window, and the next retail move waits on Ofgem’s arithmetic—not on a surprise British Gas press release this week.
