24-hour boiler repairs in South Street
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 South Street customers genuinely need us. For overnight emergencies we'll triage by phone and get out at first light. Most South Street 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.
Gas Safe Registered
Every gas job legally signed off
18+ years on the tools

Real human on the phone
Most calls answered the same day, often within the hour.
Locally based in South Street

About South Street
Older central Stortford street with period properties and conservation considerations.
Strong mix — Victorian terraces in the old centre, post-war housing in Thorley, and large new-build estates expanding north.
- New-build combi boilers approaching first major service interval
- Victorian terrace flue routing constraints
- Hard water from the chalk aquifer accelerates scale build-up in heat exchangers
Why South Street customers pick us for boiler repairs
We've been doing boiler repairs in Bishop's Stortford 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.

boiler repairs in South Street: questions we get a lot
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?▾
If you need someone literally on-site at 3am, the national chains have that. If you can wait a few hours, you'll usually get a better job, a fairer price and a real engineer by waiting for us.
How fast can you come out?▾
We aim for same-day on no-heat and no-hot-water situations. Tell us when you call if anyone elderly or with young children is in the property — we prioritise.
Is it worth repairing an old boiler?▾
Honest answer: if it's over 12 years old and the repair is more than £400, replacement usually makes more financial sense. We'll lay out both options without pressure.
