What affects the cost of replacing a radiator?
Several factors can influence how much you pay:
Radiator size and type: Larger, designer, column, or towel radiators cost more
Radiator location: Awkward access or tight spaces increase labour time
Project complexity: Draining the system, rerouting pipes, or system balancing adds cost
Condition of pipework: Older or damaged pipes may need replacing
Valve upgrades: TRVs or smart valves increase the overall price
Radiator fitting costs
Labour is often included in radiator replacement quotes, but your final cost will depend on:
Radiator size and type
Whether any pipework changes are needed
If the system needs to be drained, flushed, or balanced
If you've opted for TRVs/smart valves
Typical labour costs
Cost to fit a radiator: typically £200–£300, depending on size and pipework
Moving a radiator: around £275
Labour costs may be higher for designer radiators, older pipework, or properties in London and the South East.
Common add-ons
Remove radiator only: £80
Remove radiator and repair any minor leaks or valve issues: £100-£150
Remove up to six radiators and flush the central heating system: £350
Supply & fit cost by radiator type
Single panel radiator: £150–£250
Double panel radiator: £180–£300
Horizontal radiator: £160–£280
Vertical radiator: £200–£350
Column radiator: £220–£400
Heated towel radiator: £180–£320
If you’re upgrading multiple radiators, ask your tradesperson whether the system will need draining or rebalancing — this can affect both cost and disruption.
