Gas Safe Boiler Repairs, Service and Installations in Watford

We’re based just outside Watford in Borehamwood, so getting an engineer to you doesn’t mean joining a queue behind jobs across town.

Nothing gets swapped until we know why. A boiler losing pressure, refusing to fire, or cutting out is almost always down to one of a few causes — fan failure, ignition problems, a faulty PCB. We identify which one it actually is first.

An honest call on repair versus replacement. We look at the boiler’s age, how often it’s needed fixing, and what another repair would cost. Where replacement’s the better move, you’ll walk away with a fixed installation quote on the day.

Great service! We had a leak in the middle of the night and called Primefix around midnight. The job was booked straight away, and the engineer arrived in less than an hour. Aurel inspected our bathroom, quickly found the source of the leak, and fixed it on the first visit. He saved us a lot of trouble and kept the damage to a minimum. Highly recommended! Primefix will definitely be my go to company from now on.

Losing over 40 litres of water a day. Previous firm sent two Engineers daily, cost thousands, never found the leak. PrimeFix sent one engineer the same day I booked. James was brilliant, found it in a couple of hours and left a detailed written report with photos for insurance. That is the difference between a bill and a result

Owner's reply
Thanks so much for your kind review really glad James got to the bottom of the leak quickly and left you a proper report , we will pass this to James Thanks for choosing PrimeFix

Watford Boiler FAQs

Quick answers to the boiler questions we're asked most often. Anything you're still unsure about? Call 02081080400 and we'll talk it through.

How quickly can you get an engineer to Watford?

Borehamwood is a short hop from Watford, so it sits comfortably inside our fastest response window. No heat or no hot water always jumps the queue.

 

It largely comes down to the boiler’s age and how often it’s been breaking down. We won’t make that call over the phone — we’ll have a look in person first and tell you straight what makes sense.

 

Yes — we register the manufacturer warranty and handle the building regs paperwork ourselves, as a standard part of the install rather than an add-on cost.

 

Usually, yes. Provided the visit goes ahead as booked and nothing holds up the check, you’ll leave with the certificate on the day.

 

If that turns out to be the case, we’ll tell you at diagnosis stage and go through whether repair still makes sense before anything’s agreed. We won’t proceed without talking it through with you first.

 

£99 covers the first hour, with an additional half-hour rate if the job runs longer. Most repairs are done within an hour or two, and you’ll have a fixed price agreed before any work starts, not revised afterwards.
