Herts Boilers® is the local trading name of Express Gas & Electrical Ltd (EG&E Ltd), serving St Albans, Harpenden, Radlett, Hatfield, Watford, Hemel Hempstead and Welwyn Garden City. We are a Gas Safe and NICEIC registered local company, specialising in gas boiler and central heating repairs.
As gas engineers with electrician qualifications and experience, we are in a very unique position regarding boiler and central heating repairs. We repair all types of gas boilers and commit to fixing your boiler the same day — assuming parts are available before 3pm.
We will try our best to fix your boiler, and will not suggest a new one in most cases. We don't get paid for just turning up. We don't create extra work by faking faults or guessing the cause. We simply do the right job.
— Ming, founder & lead engineer

We have enough work coming in — we don't need to make it up. That's the principle the whole business is built on.
95% of boiler breakdowns are caused by one failed part. We find that part and fix it — not change a series of parts at your cost.
Mon–Fri working hours, you don't pay if we can't fix it. Exceptions: rented property, commercial, emergency callout.
By the job, not by the hour. Major chargeable items and labour are discussed with you before we proceed.
We're not on commission to flog you a new boiler. If yours can be saved cheaply, that's what we'll tell you.
Dual-registered for both gas and electrical work — rare for a domestic boiler engineer, useful when wiring is the actual fault.
Most enquiries come through word of mouth and Google. That's the only marketing we need — and the only standard we work to.
I don't do reviews in general, but this is a worthy one. Our heating and hot water went down in early Feb. I'd had three quotes — all different, all guessing — I was on the verge of spending £3k. Ming came round and within an hour had the system back up. Tidy, methodical, conscientious. It cost me £200. He literally saved me £3k.
We cannot thank Ming enough. We had very low hot water pressure and were told by two engineers via our energy supplier that we needed a new water cylinder. Instead of just quoting, Ming did a much more thorough analysis and managed to clear the airlock after detaching some old pipes. £70 — and he saved us so much more.
We've used this company twice and both times they've been amazing. Ming quickly diagnosed our boiler and saved us a ton of money — he found a manufacturer repair scheme we never knew about. Without his knowledge and honesty, we would have replaced the boiler, spending thousands more.
Ming went above and beyond to fix my boiler. No payment required until properly running. He saved me a fortune by diagnosing a circuit board fault. He could easily have recommended a new boiler costing thousands, but he didn't. A man of integrity with pride in his job.
Ming is the sort of boilerman you need. A real no-nonsense guy who is professional, knowledgeable, honest, and very reasonably priced. I'm sure a lot of other "experts" would have tried to sell me a new boiler or some expensive parts by now. Not Ming.
Ming is our hero. He was the fourth plumber we called to resolve issues with our newly installed boiler. He used his superior knowledge to diagnose that an error by the original fitters had caused a relatively unusual problem.
