-
I started my career in gas in 1999, completing my apprenticeship with British Gas and working my way up to Senior Technician. In that role, I led a team of 15 engineers, took on the most complex technical jobs, and trained other engineers in gas and heating systems.
In 2006, I set up my own company, Three Counties Gas & Plumbing, bringing that same standard of workmanship directly to customers across Bedfordshire, Hertfordshire and Buckinghamshire.
Boiler Priority is the next step. After years of watching heating companies spread themselves thin across plumbing, bathrooms and general repairs, I saw what customers actually needed most: speed. When your heating goes, you don't want to wait days for someone to turn up — you want it fixed.
So I stripped it back to one focus. No bathrooms, no general plumbing. Just boilers, done properly, by someone who's spent 25+ years learning how to do it right — and who still answers the phone himself.
I live locally, I work locally, and I take pride in looking after the people and homes in my community.

Priority Response
We keep dedicated emergency appointments available for boiler breakdowns, allowing us to respond quickly to local customers when heating problems can't wait.
Experienced Fault Finding
With 25+ years of experience, including 10 years as a British Gas Senior Technician, I don't believe in simply replacing parts and hoping for the best.
I diagnose the fault properly.
From electrical faults and sensors to fans, pumps, valves and intermittent problems, the aim is to identify the root causeand recommend the right solution.
Van-Stocked Common Parts
I carry a wide range of commonly required boiler components on the van, giving me the best possible chance of completing repairs during the first visit whenever possible.
If a specialist or manufacturer-specific part is required, I'll explain exactly what's needed and arrange the next step as quickly as possible.
The Goal Is Simple.
Diagnose it. Fix it. Get your heating back on.
No unnecessary work. No guesswork. No passing you around a call centre.
Just specialist boiler knowledge and a priority local response.
Boiler Hints & Tips
Quick fixes before you call — and when to stop and call us instead.
Some boiler problems are quick to sort yourself. Others aren't worth the risk. Below are a few common issues, honest advice on what you can try safely, and when it's time to hand it over to a professional.
A note on safety
The tips below are safe checks anyone can do — no gas or heating engineer qualifications required. By law, only Gas Safe registered engineers can work on gas appliances, so anything beyond these simple checks (opening up the boiler casing, working on gas or flue components, or attempting repairs) should always be left to a qualified professional.
All work carried out by Boiler Priority is done by a Gas Safe registered engineer.
Something not on this list, or not sure what's going on?
Don't guess — a quick message can save you time and a wasted afternoon.

If your radiators aren't heating properly or your boiler display shows low pressure, this is often a simple fix.
What to check: Most boilers have a filling loop (usually a grey or silver braided hose) that lets you top up pressure to the recommended level — check your boiler's manual for the exact target reading.
Pressure keeps dropping again after a day or two? That usually means there's a leak somewhere in the system rather than a one-off issue, and it's worth getting it looked at properly. [Message Andrew on WhatsApp].
🔧 Hive Smart Thermostat Reset
-
if your boiler has cut out and is showing a fault code, a frozen condensate pipe is one of the most common causes in cold weather — especially overnight.
What to check: Look for the white plastic pipe that runs from your boiler to an outside wall. If it's iced up, a warm (not boiling) water and cloth wrap around the pipe can often clear it.
Still not working, or the fault code won't clear? This is when it's worth stopping — repeatedly resetting a boiler with a genuine fault can cause further damage. [Message Andrew on WhatsApp] and we'll get it sorted.

From Our Clients

![Leighton Buzzard town centre]()
I can't rate the service and quality of work from Andrew enough. He arrived when said he world, identified the problem with my boiler and had it fixed the day the part arrived. His communication was great and he didn't take the mick with prices. A fair price for the work done. 5 Stars but could easily be more.
