How long does a boiler installation take? +
A straightforward like-for-like combi boiler replacement typically takes one day — around 6 to 8 hours. If the boiler is being relocated, the flue route changed, or you are converting from a conventional system, the job can take 2 to 3 days. Your engineer should give you a clear timeline before starting and ensure you have hot water by the end of the final day.
What are the signs of carbon monoxide from a boiler? +
Warning signs include a yellow or orange boiler flame instead of blue, dark staining around the boiler, increased condensation on windows, and a pilot light that frequently goes out. Symptoms of carbon monoxide exposure include headaches, dizziness, nausea and confusion. If you suspect a carbon monoxide leak, open windows, leave the property immediately and call the Gas Emergency Service on 0800 111 999. Fit a CO alarm near your boiler — they cost under £20 and save lives.
How long does a boiler service take? +
A standard annual boiler service takes 30 to 45 minutes. The engineer will inspect the boiler internals, check gas pressure and flow rate, carry out a flue gas analysis, and test all safety devices. You will receive a service record which you should keep as proof for your warranty. The engineer should also flag any parts showing early signs of wear.
Is a leaking boiler dangerous? +
A leaking boiler should always be taken seriously. While a small drip from a pressure relief valve may indicate a minor issue, water leaking from the boiler casing can damage internal electrics and create a safety hazard. Never attempt to repair a boiler leak yourself.

Combi, system or conventional boiler — which do I need? +
A combi boiler heats water on demand and is ideal for smaller homes with one bathroom — no tank or cylinder needed. A system boiler uses a hot water cylinder and suits homes with two or more bathrooms where demand is higher. Conventional (regular) boilers have both a cylinder and header tanks and are found in older properties. Your engineer will recommend the right type based on your home's size and hot water demand.
