NIBE Heat Pump: Best UK Electricity Tariff 2026

NIBE heat pumps are built for cold-weather reliability, with SCOP ratings up to 5.0+ and strong performance well below freezing. That efficiency profile changes which electricity tariff actually saves you the most — particularly if you're running a ground source S-series model with steadier, less peaky demand than a typical air source unit. Here's what to look for in a tariff if you own a NIBE heat pump, and how to find the one that actually fits your usage.

Why Heat Pump Tariffs

Why Heat Pump Tariffs Beats Generic Comparison Sites

Generic energy comparison sites are built for average households on flat-rate tariffs — not heat pump owners running time-of-use tariffs with usage that shifts by season and time of day. Heat Pump Tariffs uses your actual half-hourly smart meter data instead of national averages, so the comparison reflects how your heat pump really runs. Here's why that distinction matters, and what it actually changes about the numbers you see.

British Gas Heat Power explained: 10 hours of half-price electricity for heat pump owners

British Gas Heat Power gives heat pump households 10 hours of half-price electricity every day — seven overnight from midnight to 7am, and three more in the early afternoon from 1pm to 4pm. There's no peak rate. The standard rate applies for the remaining 14 hours. It's a simpler structure than Cosy Octopus and suits households that want meaningful cheap windows without managing a peak penalty.

DNO standing charges: why your electricity bill is higher than your neighbour's

Two households on identical tariffs with identical usage can pay different electricity bills — purely because of where they live. The culprit is the Distribution Network Operator standing charge, which varies across the UK's 14 DNO regions. For heat pump owners comparing tariffs, understanding this regional variation matters: it affects both your daily standing charge and, on some tariffs, your unit rates.
