MST Plumbing & Gas Services is based in Northolt and covers West London. The work is done by the same engineer who quotes it — nothing is subcontracted, and there's no call centre in the middle.
Most of our work is reactive, so we keep common spares in the van, tell you honestly whether a part is worth replacing, and would rather say a boiler is past economic repair than sell you a fix that buys three months.
We are qualified across the full domestic gas range, including unvented hot water cylinders under G3, plus commercial catering gas. If you run a takeaway, café or restaurant kitchen in West London, that second set of tickets matters, because a domestic-only engineer legally cannot sign off your fryers or range.

Common questions
What areas do you cover?
We are based in Northolt and cover all of West London, including Northolt, Greenford, Ealing, Southall, Hayes, Ruislip, Harrow, Wembley and the surrounding areas. If you are just outside, call 07300 320266 and we will tell you straight away whether we can get to you.
Are you Gas Safe registered?
Yes. MST Plumbing & Gas Services is on the Gas Safe Register under number 954088, covering domestic natural gas and commercial catering appliances. The card comes on every job and you are welcome to check it.
How quickly can you get to me?
For breakdowns and leaks we aim to get to you the same day wherever the diary allows. Call rather than email if it is urgent, because that reaches us fastest.
Do you charge for quotes?
No. Quotes for boiler installs and larger jobs are free and given in writing with a fixed price. For repairs we explain the callout charge before we set off, so nothing is a surprise.
What are your hours?
We work seven days a week, generally 7am to 9pm. Genuine emergencies outside those hours are answered where we can, with a callout charge.
Do you work on commercial kitchens?
Yes. We hold COMCAT1, COMCAT3, COMCAT4 and CODC1, which covers standard catering appliances, deep fat fryers and gas conversions in restaurants, takeaways and cafés. Not many domestic engineers can sign off catering equipment, so it is worth asking.
How much does a new boiler cost?
It depends on the boiler you choose and what the job involves, so we quote after seeing the property rather than guessing over the phone. We offer a range of packages from 5-year to 10-year warranty boilers, and every quote is fixed, written down and includes removing the old unit. Quotes are free.
