Learn moreLocal, honest heating upgrades for Little Laver homes
We've been doing heating upgrades in Ongar 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
Listen first
Cold spots? Noisy boiler? Cold rooms upstairs? We diagnose what's actually wrong before suggesting fixes.
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.
Do the work cleanly
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.
Common questions about heating upgrades in Little Laver
How often should I need to top up?▾
A healthy sealed system should hold pressure for 6-12 months between top-ups. Anything more frequent points to a leak.
Could it be the expansion vessel?▾
Yes — a perished expansion vessel inside the boiler is a common cause. We test the vessel as part of diagnosis.
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.
