Local, honest heating upgrades for Hertford homes

We've been doing heating upgrades in Hertford 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.

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

Show the before/after

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

Frequently asked questions — heating upgrades, Hertford

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.

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

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