Heat Pump Radiator Cost Per Room
Most UK homes need just 2-4 radiators upgraded for a heat pump, not all of them. Budget £200-£500 per radiator, with living rooms at the top end and bedrooms at the bottom. The total radiator budget is typically £400-£2,000 — a fraction of the overall installation cost.
Radiator costs are usually included in the overall installation quote. See our pillar: do I need new radiators?

Where to Save
- Only upgrade radiators the heat loss calculation identifies as undersized
- Standard steel Type 22 radiators offer the best value
- Fan convectors cost more but may avoid needing multiple radiators
- Insulation improvements reduce heat loss, potentially avoiding upgrades
Radiator investment pays back through lower flow temperatures and higher COP. Add solar panels for even faster payback.
