Local, honest heating upgrades for Little Dunmow homes

We've been doing heating upgrades 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 heating upgrades with us

1

Listen first

Cold spots? Noisy boiler? Cold rooms upstairs? We diagnose what's actually wrong before suggesting fixes.

2

Recommend the right upgrade

Sometimes it's a £150 magnetic filter, sometimes a £600 power flush, sometimes new radiators. We'll be straight with you.

3

Do the work cleanly

Floors covered, water drained properly, no mess left behind.

4

Show the before/after

Pressure readings, radiator temps, and inhibitor levels all logged so you can see the difference.

Quick answers on heating upgrades in Little Dunmow

What's a fair price for this job in Little Dunmow?

Pricing depends on the boiler, the existing pipework, and any system upgrades needed. We're typically 10-20% under the big national chains because we don't carry their overheads — and the workmanship is better.

Are quotes free?

Yes — quotes are always free, in writing, and there's no obligation. We don't do high-pressure sales.

How much does a power flush cost?

Typically £450–£750 depending on system size and number of radiators. We give a fixed price after a quick survey.

Will a smart thermostat actually save money?

Yes — typically 8–12% off heating bills if you use the scheduling and zone features properly. Hive and Nest both pay back inside two years for most households.

What you get when you book us

  • MagnaCleanse and Kamco flushing equipment
  • Boiler Plus compliant installs
  • Smart thermostat brand-agnostic — Hive, Nest, Tado, Honeywell, Drayton
