From first call to handover — our boiler installs routine

We measure up, check radiator output, and confirm the gas pipe size is right — undersized supply pipes are the most common reason boilers underperform after install.
Quote & options
Two or three boiler options at different price points so you can pick what fits your budget.
Install
Old boiler removed, new one fitted, system flushed, controls set up. Usually a single day for a straight swap, two for a full system change.
Aftercare
Annual service reminders, plus a real human at the end of the phone if anything plays up.
