What London's winter means for your heat pump

In London, the average January low is -8°C, and the coldest temperature recorded from 2015-2024 was -31°C. That's milder than 29% of the 123 cities we track. That's true cold-climate territory. Ask for models rated to keep heating near your coldest temperatures, compare each model's heating output at -25°C, and plan for backup heat on the worst nights.

Before you hire a heat pump installer

  1. Ask for a room-by-room heat loss calculation. A quote that guesses the size from square footage alone is a red flag.
  2. Ask for the exact model and its heating output at your area's coldest temperature, not just the brand.
  3. Ask who handles the rebate paperwork and whether the model is on your rebate program's eligible list.

Before you call anyone, check what heat pump rebates you can get in London. Many programs require approval or a registered contractor before work starts.
