From first call to handover — our boiler installs routine
Site visit
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.
boiler installs in Great Dunmow: questions we get a lot
Why don't you publish fixed prices online?▾
Because every job is different. The "from £1,499" you see on national sites almost never includes flue, system flush, controls, or any pipework changes — the bits that always come up.
How long does a boiler install take?▾
A straight combi swap is usually one day. A boiler relocation, conversion, or full system change is typically 1–3 days.
Which boiler brand do you recommend?▾
Worcester Bosch and Vaillant for long warranties and parts availability; Ideal Logic Max for budget-conscious installs. We'll explain trade-offs honestly.
