24-hour boiler repairs in Ongar
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 Ongar customers genuinely need us. For overnight emergencies we'll triage by phone and get out at first light. Most Ongar 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.

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.

Common questions about boiler repairs in Ongar
Are you open right now?▾
We answer the phone from early morning until late evening on most days. Even outside hours, leave a message and we usually call back within a couple of hours for genuine emergencies.
Should I call a national 24/7 firm instead?▾

Do you guarantee repairs?▾
Yes — 12 months on the workmanship and any parts we supply.
