A small firm, based in Northolt

MST Plumbing & Gas Services covers West London, with around 35 years of combined experience on the tools.

Between a long career on the tools and more recent training, we cover the full domestic gas and plumbing range, plus commercial catering gas. The years of experience mean very little in a West London house is unfamiliar; the current qualifications mean the regulations we work to are up to date, which matters more than people realise in a trade where the rules change.

We deliberately stay small. It means the person who prices your job is the person who does it, you get a phone number that reaches an engineer rather than a receptionist, and nobody is working to a daily job target that pushes them to rush your house to get to the next one.

How we work

Most of our work is reactive. Somebody's boiler has stopped, or there is water coming through a ceiling, and they need it dealt with. That means we keep the diary flexible enough to fit emergencies in, and we carry the spares that cover the most common faults.

On bigger jobs like a boiler install, the price is fixed and in writing before anything starts. We would rather spend twenty minutes looking at a job properly and give you a real number than quote a range over the phone and revise it upwards on the day.

And when something is not worth fixing, we say so. Charging somebody for a major repair on a fifteen-year-old boiler when a new one makes more sense is an easy way to earn a day's money and lose a customer for good.

Qualified for more than most

Alongside the standard domestic gas tickets we hold the unvented cylinder qualification (HWSS, which Building Regulations G3 requires) and the full commercial catering set: COMCAT1, COMCAT3, COMCAT4 and CODC1. That last group is what lets us work legally on restaurant and takeaway kitchens, and it is unusual for a firm of our size to carry it.
