Welcome to our gas boiler installation cost estimator, this tool will help you get an idea of how much it will cost to install a replacement combi, conventional or system boiler in your home. For more information on the difference between boiler types, visit our “central heating & boilers explained” page.
The cost estimator will present you with a variety of different boiler types from leading manufacturers, with all the additional options needed to create a long lasting and energy efficient hot water and central heating system.
The calculator assumes a gas supply is available.
If you like the installation and boiler estimator results, we’d be happy to pop round, survey your property and confirm a fixed price quotation.
Any estimate given on this page is for illustrative purposes only. This tool assumes straightforward circumstances without complications.
Calculations are based on one day jobs, an unchanged flue terminal position and making use of existing gas pipework. All prices provided are subject to VAT at the current rate and survey of your property will be required for a fixed price quotation. Prices used in this estimator are current as of July 2017.
