What are we talking about?

How long does it typically take to change a radiator valve?

Typical time

There is no typical time for this task but a series of questions to ask.


May require a system drain down and refill

Questions to ask

Central heating system type (e.g. boiler with immersion cylinder, combi), current valve and pipework condition, space between floor and radiator valve, whether pipes are surface mounted (i.e. around the wall) or under the floor, type of floor if access is required.


Firstly we need to ascertain whether a repair is not more appropriate. Some thermostatic valves can be repaired as they often 'stick' when little used. Leaks can sometimes be repaired.

If an entire replacement valve is required the next step is to see if the work can be achieved using pipe freezing (requires a good length of accessible pipe) or whether a drain down of the central heating system and a refill after the work is completed is required. If draining down an inhibitor will need to be added. For multiple valves a drain down is usually quicker. Floor coverings such as carpet need to be protected.

Refills can mean the need to get airlocks out, particularly in larger / older properties.

Before starting this job we need to ensure that the system is working well and all radiators reach a satisfactory heat level.

If a fitted carpet needs to be removed then it may be worth considering getting a carpet fitter to relay it.
