Frequently asked questions
Do you fit new boilers and full central heating systems?
Both — from a like-for-like combi swap to a designed whole-house system with room-by-room heat-loss calculations. Every installation is Gas Safe notified, commissioned with the benchmark record completed, and warrantied.
What should I do if my boiler stops working?
Run the safe checks first: thermostat and programmer, gas at other appliances, pressure gauge (top up via the filling loop if low), and in freezing weather the external condensate pipe. Then one reset. Our no-heating guide covers all eight checks in order.
Do you install heat pumps in Cardiff?
Yes — through MCS-certified installers, which is both the quality standard and the requirement for Boiler Upgrade Scheme grant support. Every heat pump quote starts with a room-by-room heat-loss survey rather than a guess.
What if I smell gas?
Leave the property, don't touch electrical switches, and call the National Gas Emergency Service free on 0800 111 999 immediately. That call comes before any repair booking — once the property is made safe, we can arrange the follow-up repair.
Is hard water a problem for boilers in Cardiff?
Cardiff's Welsh Water supply from Brecon Beacons reservoirs is soft — scale is a minor player, and the city's heating and hot-water work leans toward Victorian terrace pipework and the huge Cardiff Bay apartment stock. Where the water is hard, scale protection on the boiler's supply and properly inhibited system water are what keep heat exchangers alive — and our engineers advise on both as part of servicing and installation.
