Learn moreLocal, honest heating upgrades for Great Amwell homes
We've been doing heating upgrades in Ware 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.

Pressure readings, radiator temps, and inhibitor levels all logged so you can see the difference.
Things Great Amwell customers usually ask about heating upgrades
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.
Do I really need a power flush?▾
If radiators have cold patches, your boiler is noisy, or you're fitting a new boiler to an older system, yes. Otherwise a chemical flush and magnetic filter is often enough.
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.

- Rebalancing included with every flush
- MagnaCleanse and Kamco flushing equipment
- Sentinel X100 inhibitor used as standard
- Boiler Plus compliant installs
