A new boiler installation usually takes 1-3 days. If your new boiler is the same type as your old one, it will be a simpler and quicker boiler installation than if your replacement boiler was a different type – for example, switching from a conventional boiler to a combi boiler. Moving your new boiler to a different place to the old one makes your replacement boiler installation slower than keeping the same type because it creates extra work like changing the pipework.

Installing a new boiler in your UK home typically costs between £1,500 and £5,000. The price of boilers can fluctuate based on the size and type required. For example, combi boilers range from £500 to £3,000, conventional boilers cost between £600 and £3,500, and system boilers are priced from £580 to £3,500

After 2025, oil boilers are expected to be replaced by more eco-friendly heating systems, such as air-source heat pumps, ground-source heat pumps, or hydrogen boilers. These options provide lower carbon emissions and are aligned with the UK's sustainability goals.
