Our Story
JBT Plumbing & Heating (Alnwick) Ltd is led by James Bell-Taylor — a Northumberland-born specialist with a single, simple philosophy: every heating system we install is designed from the start to deliver the lowest possible running costs and the highest comfort, for years to come.
We work across Alnwick and the wider Northumberland area. We commission leading boilers for maximum efficiency, design complete systems with full heat-loss calculations, install Air Source Heat Pumps and LPG, and look after the everyday plumbing that keeps homes running. Whatever the job, you'll have constant communication with us — from first survey until the system is signed off.
Heating System Design
Most heating systems underperform because they were never properly designed in the first place. We use the latest technology to calculate the heat-loss of every room, size the system correctly, and produce a full printed report so you know exactly what you're paying for — and exactly what it will deliver.

Our Services
From a new heating system designed from scratch to a leaking tap on a Saturday morning — eight core services covered by one experienced, local team.
We install leading boiler brands and commission them for maximum efficiency and performance. Every system is designed before it's installed — so it does exactly what it's supposed to, for as little as possible to run.
Annual servicing keeps your boiler safe, efficient and running for longer — and maintains the manufacturer's warranty. Quick, clean visits, with everything documented.
Landlord gas safety certificates and homeowner safety inspections — a legal requirement for landlords, and peace of mind for everyone. We turn paperwork around fast.
Using the latest design technology, we produce full heat-loss calculations and complete printed reports. Designed from start to finish for the best possible results — and the lowest possible bills.
A clean system is an efficient system. Our full range of flushing solutions combats a wide variety of issues — cold spots, noisy radiators, slow response — and gets your heating performing the way it should.
Expert leak detection, rapid response and a clean repair — before a small drip turns into a flooded floor. We trace, fix and reinstate, with as little disruption as possible.
A thorough plumbing system inspection identifies potential issues before they become major problems. Ideal for new owners, landlords and anyone planning works.
Tap repairs and replacements, toilet repairs, showers, baths, radiator swaps and everything in between. The everyday plumbing that keeps homes running — done properly the first time.
