Can I change my boiler’s location?

There is absolutely nothing stopping you from changing the location of your boiler when you get it replaced. You might want to free up space in a room or hide it away in a cupboard. All you need to consider is that the new location is near an external wall so the flue can be vented and that access is always available to the boiler for any maintenance or repairs that need carrying out.

The time and cost of changing a boiler’s location will depend on how far it is being moved. The further it is moved from its original location, the more work is required. Additional pipework will need to be installed, which may involve an engineer having to lift carpets and floorboards. It usually takes between half a day and a day to do this.
