Trusted for heating upgrades across Hockerill
Our heating upgrades work in Bishop's Stortford is built around three things: doing it properly, charging fairly, and being there afterwards if you need us.
Power flushes pay for themselves quickly here because of the hard water — we typically pull out a kilo of black sludge from a 10-year-old system.
If something plays up in the first year, we come back and sort it. No quibbles, no callout fee.

- New-build combi boilers approaching first major service interval
- Victorian terrace flue routing constraints

Frequently asked questions — heating upgrades, Hockerill
Where do boiler leaks usually come from?▾
Most common: pressure relief valve discharging because system pressure is too high, a perished pump seal, or a failing heat exchanger on older units. We diagnose properly rather than guess.
Should I turn the boiler off?▾
If water is actively dripping and you can see it pooling, yes — switch the boiler off at the spur, and turn the system pressure down via the filling loop if you can. Then call us.
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.
