Pilot light out in South Street? Boiler repairs sorted properly
Pilot light keeps going out on an older boiler in South Street? That's usually a thermocouple failing, a draught problem, or a gas supply issue. Older units (back boilers and pre-2005 conventional models) we can usually keep running with the right parts. 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.

Things South Street customers usually ask about boiler repairs
Is a pilot light boiler still safe to use?▾
Yes if it's serviced annually and the thermocouple and flame failure devices are working. We test all of these on every service.
Should I just replace it?▾
If parts are getting hard to source or the boiler is over 15 years old, replacement is usually the right call. We'll be straight with you on the numbers.
Do you guarantee repairs?▾
Yes — 12 months on the workmanship and any parts we supply.
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.
