Learn moreAbout Katherines
Newer estate on Harlow's western edge with predominantly combi-boilered housing.
Predominantly 1950s–70s post-war housing with a mix of terraces, semis, and 60s-built flats. Pockets of older stock around Old Harlow.
- Original 1960s flats often have undersized gas supply pipes that limit modern combi performance
- Older Old Harlow properties frequently have low mains water pressure that affects combi choice
- Many 60s/70s back boilers still in service — our regular work involves removing these and reinstating fireplaces

boiler servicing in Katherines: questions we get a lot
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 long does a service take?▾
Usually 45–60 minutes for a domestic boiler in normal condition.
How often should a boiler be serviced?▾
Once a year. It's almost always required to keep the manufacturer's warranty valid, and it catches small issues before they become breakdowns.
