How long does it take to install a replacement boiler?
Installing a new boiler usually takes 1-3 days. If your new boiler is the same type as your old one, it will be simpler and quicker than if you were changing to a different type – for example, from a conventional boiler to a combi boiler. Keeping your new boiler in the same place as the old one will make installation quicker than relocating it, as this creates extra work like changing the pipework.
What happens when a new boiler is fitted?
Your engineer will drain down your central heating and hot water system so that they can disconnect and remove your old boiler. They will then clean out your heating system to get rid of impurities in the system pipework. They’ll then install your new boiler and check that everything is working as it should be. Once that’s done, they’ll talk you through the boiler and system controls and show you how to use it. Our step-by-step guide to new boiler installations explains everything in more detail.
What happens after a new boiler is fitted?
Once your expert engineer has installed your new boiler, they’ll check that everything is working as it should be and then talk you through the boiler and system controls and show you how to use it. Our step-by-step guide to new boiler installations explains everything in more detail.

What is the cost of a new combi boiler?
The size of your home and the number of radiators it has will determine the cost of a new combi boiler. A new combi boiler for a small one-bedroom flat with only five radiators will cost much less than a new combi boiler for a large detached house with lots of bedrooms, bathrooms and radiators.
