Frequently Asked Questions

How quickly can you repair my boiler in Dover?

We aim to attend boiler repairs in Dover as quickly as possible, often within 24-48 hours. For emergencies such as gas leaks or complete breakdowns in cold weather, we offer priority response.

How much does a boiler repair cost?

Repair costs depend on the fault and the parts required. As a general rule, we only provide formal quotes for boiler installations. If we attend a breakdown, we carry out an initial diagnosis and then, where possible, give you an idea of the costs to repair before carrying out any work.

Is it worth repairing my old boiler or should I replace it?

As a general rule, if your boiler is over 10-15 years old and needs frequent repairs, a replacement may be more cost-effective in the long run. We will give you honest advice on whether a repair or replacement makes more sense for your situation.

My boiler is showing a fault code — what should I do?

First, check our boiler fault code guides for your boiler brand — many common fault codes have simple fixes like repressurising or resetting. If the issue persists, do not attempt to repair it yourself. Call us and we will diagnose and fix the problem safely.

Do you repair all boiler brands?

Yes, our Gas Safe registered engineers can diagnose and repair all major boiler brands including Worcester Bosch, Vaillant, Baxi, Ideal, Glow-worm, Alpha, and more.

Why has my boiler lost pressure?

Low boiler pressure is usually caused by a small leak in the system, a recently bled radiator, or a faulty pressure relief valve. You can try repressurising the boiler using the filling loop, but if the pressure keeps dropping, there may be an underlying issue that needs professional attention.

My boiler keeps cutting out — what could be wrong?

A boiler that keeps switching off could be caused by low water pressure, a faulty thermostat, a blocked condensate pipe, or an issue with the pump or fan. It is best not to keep resetting it repeatedly. Call us and we will diagnose the root cause.

Why is my boiler making a strange noise?

Banging, whistling, or gurgling noises from your boiler can indicate trapped air, limescale build-up, low water pressure, or a failing pump. These noises should not be ignored as they can lead to bigger problems. Get in touch and we will investigate.
