How long does it take to install a new boiler in a house?

Depending on the size of the work and the kind of boiler being installed

Your boiler installation might take anywhere from four to six hours to several days. Our guideline will give you an idea of how long it will take to remove the old boiler and install the new one.

If you already have a combi boiler and want to replace it with a new one, the process usually takes four to six hours. This is the simplest kind of combi boiler installation. It is often referred to as a ‘like for like swap’.

This may not seem to be a lot of time, but since the majority of the work has already been completed, there isn’t much for the Gas Safe expert to do in this installation situation to equip a new boiler.

The installation period will be longer if you wish to switch from a cylinder boiler to a combi boiler. This is because the boiler installation may need the construction of extra pipes. Because there is a tank and a heating cylinder, removing the old boiler will undoubtedly take longer. The whole duration is projected to be two to three days, providing the new boiler is put where the previous one was.

If you want to install your new boiler in a different spot from where the old one was, this will also take extra time, potentially up to three or four days in total. Again, this is mainly due to having to install more pipework to accommodate the location change.
