How much does radiator installation cost in the UK? (2026 guide)

Updated 6 November 2026 · By the Radiator Installation team

Short answer: In 2026, replacing a single radiator like for like in the UK usually costs £180 to £400 including a standard double-panel radiator, or £150 to £300 for labour only. Fitting a radiator in a new position with new pipework usually costs £300 to £650, and replacing all the radiators in a typical three-bedroom house usually costs £2,000 to £4,500.

Typical prices

Job	Typical UK price (2026)
Like-for-like swap, labour only	£150 to £300
Like-for-like swap, standard radiator included	£180 to £400
New radiator in a new position, with pipework	£300 to £650
Moving an existing radiator	£200 to £500
Heated towel rail, supplied and fitted	£200 to £450
Designer or column radiator, supplied and fitted	£350 to £900 or more
TRV fitted (per radiator)	£40 to £90
All radiators in a 3-bed house	£2,000 to £4,500

These are typical guide prices. Your actual price depends on the radiators chosen, the amount of pipework, access under floors, the type of heating system and where in the UK the property is.

What affects the price

Like-for-like swap or new position
Radiator style, size and finish
Pipework changes and lifting floorboards
Number of radiators done in one visit
Type of system, such as combi, system or open-vented
Whether a power flush or system clean is needed first

Is it cheaper to do several at once?

Yes. The system only needs to be drained, refilled, dosed with inhibitor and balanced once, so the cost per radiator falls when several are replaced in the same visit.

How to get an accurate price

Send the number of radiators, the rooms they are in, photos of the existing radiators and valves, and whether you want any moved. That is enough for a fixed price in most cases.
