Radiator replacement cost breakdown
What a radiator replacement typically costs, by the unit:
| What | Typical UK cost |
|---|---|
| Per radiator, supplied and fitted | £110 to £200 per radiator |
| + Designer, vertical or column radiator | add £100 to £350 per radiator |
| + Add a brand-new radiator (new pipework) | add £150 to £350 per radiator |
| Typical 1 radiators | £110 to £200 |
What's included in the price?
A typical radiator replacement price includes:
- Draining down the radiator or the local part of the system
- Removing the old radiator and disposing of it
- Fitting the new panel radiator to the existing brackets or new brackets
- Connecting to the existing valves and pipe tails
- Refilling, bleeding and rebalancing that radiator
- Checking for leaks and confirming it heats through
What changes the price?
The things that move a radiator replacement price most:
Moving the radiator to a new spot, which means new pipework and more time
Fitting a designer, vertical or column radiator rather than a standard panel
Adding a brand-new radiator where none existed, needing fresh pipe runs
Whether the whole system must be drained, or just the one radiator isolated
A power flush or system clean carried out at the same time
How the price is built up
The base figure is the labour to drain, remove, fit and rebalance a like-for-like radiator, usually £110 to £200 per unit for a job of 1 to 2 hours. On top of that sits the cost of the radiator itself, cheap for a plain panel but far more for a designer or column model. Moving the radiator, running new pipework or draining the full system all add labour and lift the total well above the base rate. Most of the price is labour, with a standard steel panel radiator costing only about £40 to £150, while designer units run much higher.
Ways to keep the cost down
- Keep the new radiator the same size and in the same place so it is a straight swap with no new pipework
- Buy the radiator yourself from a merchant rather than paying a trade markup, then check the valve centres match
- If you are changing several radiators, book them in one visit so the system is only drained once
- Only pay for a power flush if the system is genuinely sludged up, not as a default add-on
Does where you live change the cost?
Expect around £150 in the north and £200 to £300 in London and the South East for the same swap.
Common questions
Replacing a radiator with the same size in the same position usually costs about £110 to £200 for the swap, and around £180 all in for a typical job. That covers draining down, removing the old unit, fitting the new one to the existing valves and pipes, then bleeding and rebalancing. A basic steel panel radiator adds roughly £40 to £150 on top if you need to buy one.
Radiator jobs climb above the basic swap when the work grows. Moving the radiator to a new wall means fresh pipework and more labour, often £150 to £400. A designer, vertical or column radiator costs more to buy and fit. Adding a brand-new radiator on new pipe runs, or draining the whole system rather than isolating one rad, all push the figure up. Difficult access or concrete floors add more again.
Draining the whole system is often unnecessary for a single swap. A heating engineer can usually isolate one radiator at its valves, drain just that unit, and change it without emptying the rest, which keeps the job to 1 to 2 hours. Draining down fully is more likely when you replace several radiators at once, when valves are seized, or when the system needs a clean at the same time.
Designer, vertical and column radiators cost more than a plain panel because the units are pricier and take longer to fit and align. Budget roughly £100 to £350 per radiator on top of a standard swap, so a fitted price often lands between £220 and £700 depending on size and finish. Tall vertical rads in particular need careful bracket placement and sometimes adjusted pipework.
Adding a radiator in a room that never had one costs more than a swap because new pipework must be run to it from the existing circuit. Expect around £150 to £350 above the base rate for the pipe runs and extra labour, and more if floors are concrete, access is tight, or the run is long. The heating engineer will also check the boiler and system can handle the extra load.
A power flush is worth considering when radiators are cold at the bottom or the system is full of sludge, but it is a separate job, not part of a swap. It typically adds £400 to £800 depending on the number of radiators. If you are only changing one clean radiator it is usually not needed. When fitting several rads or a new boiler, a flush protects the new parts from existing debris.
