Learn moreLocal, honest boiler installs for Great Dunmow homes
We've been doing boiler installations in Great Dunmow long enough to know which streets have shared chimneys, which estates have undersized gas supplies, and which boilers tend to fail first.
That experience means we get the spec right at the survey, not halfway through the install.
And we don't cut corners on the bits you can't see — proper pipework, magnetic filter, full system flush where needed.
What happens when you book boiler installs with us
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.
