The Warmside way
Founded in Kirkstall in 1989. Stone terraces, back-to-backs, new builds — we’ve heated them all.
Care-plan members pay nothing to have us at the door, and nothing extra for parts or labour on Warm Home and above.
Straight-swap combi installs are usually finished and explained the same day.

★★★★★
Emergency repair + Warm Home plan“Our boiler packed in during that cold snap and Warmside had an engineer out the same morning. Calm, tidy, explained everything. We have been on a care plan ever since and would not go anywhere else.”
★★★★★
New boiler installation“Fixed-price quote for a new Worcester combi, fitted in a day, and they actually left the airing cupboard tidier than they found it. The monthly finance made it painless.”
★★★★★
Landlord gas certificates“I manage six rentals and Warmside handle every CP12 and service. Digital certificates land in my inbox the same day. One less thing to chase.”
Plain answers
A new gas combi boiler fitted in Leeds typically costs between £1,895 and £3,200, depending on the boiler brand, whether the flue and pipework need moving, and your guarantee length. Warmside quotes a fixed, itemised price up front, and you can spread it from around £39 a month on finance.
Once a year. An annual service keeps your manufacturer warranty valid, keeps the boiler running efficiently, and catches worn parts before they fail in winter. Most boiler warranties are void without proof of an annual service by a Gas Safe registered engineer.
Yes. Every Warmside engineer is on the Gas Safe Register — the official list of gas engineers legally allowed to work on gas appliances in the UK. Our registration number is 319864 (demo number — illustrative only). You can ask to see any engineer's ID card on the doorstep.
A care plan spreads the cost of looking after your heating across small monthly payments. It always includes your annual service, and the higher tiers add breakdown cover with no call-out fees or excess. For most households a plan works out cheaper than one unplanned repair, and it means help is a phone call away.
Yes. We offer boiler finance from 0% APR over shorter terms up to longer plans at 9.9% APR, so a new boiler can start from around £39 a month. Use the finance calculator on our site to see your monthly figure before you commit — there is no obligation.
We cover all of Leeds and the surrounding villages, including Roundhay, Horsforth, Headingley, Chapel Allerton, Kirkstall, Meanwood, Adel and Alwoodley. If you are within about ten miles of Leeds city centre, we can help.
Open your doors and windows, do not touch any electrical switches, put out naked flames, turn the gas off at the meter if you can reach it safely, and leave the property. Then call the National Gas Emergency Service free on 0800 111 999. Once you are safe, call us and we will help put things right.
Care-plan members get priority and we reach most weekday breakdowns the same day. For everyone else we aim to be with you within 24 hours. Our 24/7 emergency line is answered by real people, not a call centre.
