At SOS Boiler Engineers, our Gas Safe registered team is equipped to diagnose and repair the most frequent boiler issues quickly and effectively. Here are the key signs your boiler needs our professional attention:
Left in the cold with no heat or hot water? Whether it’s a faulty thermostat, broken diaphragm, or pressure issue, we deliver urgent boiler repairs—same-day if you call by 12pm.
Banging, whistling, or gurgling noises coming from your boiler? These could signal air in the system, limescale buildup, or a failing pump. Our engineers diagnose and fix the problem before it worsens.
A leaking boiler—caused by corroded components, a faulty pressure valve, or poor installation—can damage your property. We stop leaks fast with durable, precise repairs.
If your pressure gauge reads below 1 bar, your boiler may struggle to heat. We address leaks, air blockages, or valve issues to restore full efficiency to your system.
Is your pilot light flickering or out? This could stem from a thermocouple fault or gas supply issue. Our Gas Safe experts resolve it safely and swiftly.
Cold or uneven radiators? We fix blockages, air pockets, or pump failures to ensure your central heating warms every corner of your home.
