24-hour boiler repairs in Harlow
We're not a true 24/7 chain — we're a small local team — but we pick up early, stay late, and respond fast when Harlow customers genuinely need us. For overnight emergencies we'll triage by phone and get out at first light. Most Harlow repair callouts we diagnose and fix on the first visit — common parts (PRVs, diverters, pumps, PCBs) live on the van.
You're not getting a call centre — you're getting Grant.
The same engineer quotes the job, does the work, and answers the phone afterwards if anything's not right.

About Harlow
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

Learn moreLocal, honest boiler repairs for Harlow homes
We've been doing boiler repairs in Harlow 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.
Diverter valve and PCB faults are particularly common across Harlow's older Worcester 24i and Vaillant ecoTEC units installed in the 2008–2014 boom.
What happens when you book boiler repairs with us
Fast response
Same-day where possible — especially for vulnerable customers or no-heat in winter.
Honest diagnosis
If your boiler is past saving, we'll tell you. We won't sell you a £400 repair on a 16-year-old unit.
Repair, replace, or part-exchange
Three options where appropriate, with honest cost/benefit on each.
Aftercare
We log the repair, register the parts warranty, and give you a service reminder.
