Q2 2026 cap stays put through 30 June

The headline number — £1,641 typical dual-fuel direct-debit — is unchanged from when it took effect on 1 April. That's the floor for SVT customers, and it's not moving until 1 July at the earliest.

For households on SVT this means: your rates in May are identical to April. If your bill looks higher, it's almost certainly usage variation rather than rate change.

Fixed-deal repricing has tightened in early May

Suppliers update fixed-tariff offers weekly. The general direction in late April / early May 2026:

  • 12-month fixed deals commonly priced 3–6% below cap (typical annual cost £1,540–£1,580).
  • 24-month fixes have widened slightly — fewer suppliers offering them, and pricing reflects more uncertainty about Q3+.
  • Tracker tariffs remain niche but interesting if you believe wholesale will fall.

Compared to April, headline best-fix rates are roughly stable but with fewer no-exit-fee options on offer.

Regulatory consultations to watch in May

A few Ofgem and government threads are running:

  • Standing charge reform. Ongoing consultation on rebalancing standing charges into unit rates. Any change wouldn't land before October at earliest, but watch for announcements in May.
  • Half-hourly settlement (MHHS). The market is mid-transition. For customers, this enables more time-of-use tariffs over coming months.
  • Direct debit rules. Tighter rules around supplier credit balances continue to roll out. Check your direct-debit balance hasn't drifted into significant credit.

What you can do this month

  • If you're on SVT: compare for your postcode. Most SVT customers can find a fix that saves £40–£100/year. Choose no-exit-fee where possible to keep options open.
  • If your direct debit feels high: log in and check your balance. Suppliers must let you reclaim credit balances above one month's bill (under tighter recent rules).
  • If you're approaching the end of a fix: set a 4-week reminder. Don't roll onto SVT silently.
  • If you're house-moving in May: note your meter readings on move day and notify both suppliers within 5 working days.

What to wait on

  • Long fixes (24m+). Better clarity after 27 May. Three weeks of patience beats a poorly-timed lock-in.
  • Q3-driven decisions. Anything contingent on what the cap does on 1 July — Ofgem confirms 27 May.
  • Time-of-use tariffs you're considering. If you don't yet have a smart meter, get one installed first — most TOU tariffs require it.

Frequently Asked Questions

Have UK energy bills changed in May 2026?

Not from the price cap — the Q2 cap (£1,641 typical) runs through 30 June 2026. Fixed-tariff pricing has shifted slightly since April, with some suppliers tightening exit-fee terms.

When is the next price cap announcement?

27 May 2026, for Q3 2026 (1 July – 30 September). Cornwall Insight and other forecasters expect a relatively small change.

Should I change my direct debit in May?

Check the balance first. If you're significantly in credit (more than a month's average bill), you can request a refund or ask your supplier to reduce monthly payments.

Are fixed energy deals cheaper in May 2026?

Yes for most households. Best fixes are commonly £60–£100/year below the cap for typical usage, although the cheapest deals may have tie-ins or exit fees.

Is it worth switching now or waiting until July?

If you're on SVT, switch now — there's no benefit to waiting. If you're considering a long fix, 27 May gives more clarity before committing 24 months.
