Who We Are

About Heatsource Boilers

A trusted local heating company built on expertise, reliability, and genuine care for our customers.

Heating You Can Count On

Heatsource Boilers is a trusted local heating company serving Winchester, Hampshire and the surrounding counties. We've been providing reliable, high-quality heating services to homeowners, landlords, and businesses for decades.

Led by John Horobin — a Gas Safe and OFTEC registered engineer with a career built on doing things right — Heatsource Boilers has earned a reputation that speaks for itself. John is supported by Ben Truman, an experienced and highly regarded heating engineer known for his professionalism and reliability.

We believe heating engineers should be straight-talking, fairly priced, and actually turn up when they say they will. That's what we do, every day. Whether it's a routine annual service, an emergency breakdown, or a full boiler installation, you'll always get the same dependable team.

We're proud to be a Worcester Accredited Installer — meaning your new boiler comes with the manufacturer's extended warranty, giving you real peace of mind. And as a small local business, we genuinely care about every customer we work for.
