British Gas Heat Power tariff rates 2026: confirmed rates for every UK DNO region

Overview

British Gas Heat Power (current version effective from June 2026, fixed until June 2027) is a dedicated heat pump tariff with 10 hours of half-price electricity daily. There is no peak rate — standard rates apply at all other times, meaning you're never penalised for running your heat pump at the wrong moment.

Rate structure:

• Off-peak: 00:00–07:00 and 13:00–16:00 (10 hours/day) — half the standard rate
• Standard: all other hours (14 hours/day) — at the standard cap level; no premium applies

Current British Gas Heat Power rates by DNO region (June 2026)

The rates below are the confirmed current figures pulled directly from the tariff database. British Gas Heat Power has regionally differentiated rates across all 14 UK DNO regions.

How the rate structure works

Overnight window (00:00–07:00): Seven hours of cheap electricity overnight. The rate of approximately 16.27p/kWh in the Eastern region is significantly below the standard cap, making it suitable for hot water cylinder reheating and overnight space heating. At 7 hours, the window is long enough to fully recover a 250-litre cylinder with time to spare.

Midday window (13:00–16:00): Three additional hours in the early afternoon at the same cheap rate. This window is particularly valuable for heat pump efficiency: outdoor temperatures are typically warmer at 13:00–16:00 than overnight, meaning the heat pump achieves a higher COP during these hours — a rate discount and an efficiency bonus simultaneously.

Standard rate (all other hours): Approximately 32.55p/kWh during standard hours. Note that this is above the Ofgem standard cap — British Gas Heat Power is a fixed tariff, and the standard rate reflects anticipated cap rises over the fixed term (to June 2027). No peak premium applies at any time of day.

70 hours of cheap electricity per week

British Gas frames Heat Power as providing 70 hours of half-price electricity per week (10 hours/day × 7 days). That figure compares well with other dedicated heat pump tariffs:

Heat Power has more cheap hours than Cosy Octopus and EDF FreePhase, and crucially no peak rate at any time.

Is British Gas Heat Power right for your home?

Heat Power suits households that want substantial cheap-hour coverage without any peak-rate exposure. It's particularly well suited to households that can't reliably avoid a peak window — with Heat Power, there's no peak to avoid. The midday window is a genuine advantage over tariffs with overnight-only discounts.
