Fixed vs variable tariffs for heat pump owners: which gives a lower bill in 2026?

Most fixed vs variable comparisons assume a typical household with flat usage. Heat pump owners are not typical — they use two to three times more electricity than average, most of it in winter, and a significant share is shiftable to off-peak windows. That changes the calculation considerably. A flat fixed rate competes not with the standard cap, but with the effective blended rate you'd actually achieve on a time-of-use tariff.

When is the right time to switch heat pump tariff? Seasonal timing and price cap dates explained

The Ofgem price cap changes every quarter — April, July, October, January. Each change shifts the off-peak rates on every variable heat pump tariff in the UK. Understanding that cycle helps you switch at the right moment, avoid locking in at the wrong rate, and know when to check whether your current tariff is still competitive. This guide explains the timing, what to watch for, and why summer is often the best time to switch.
