    • The boiler brand

    • System type (combi, system or regular)

    • Installation complexity

    • Any required upgrades (flue, filters, pipework)

    All quotes include Gas Safe installation, warranty activation, benchmarking and system protection.

    What’s involved in a new boiler installation?

    Your installation includes:

    • Full system inspection

    • Removal of your old boiler (if required)

    • Fitting the new boiler + flue

    • Correct gas pipe sizing

    • Magnetic filter installation

    • Powerflush or system cleanse

    • Warranty registration

    • Benchmark certification

    • System setup and handover

    We ensure everything is safe, compliant and running efficiently before we leave.
