No matter the issue, our engineers have the expertise to find the cause

Frequently Asked Questions

Common questions about our fault diagnosis service

How much does a fault diagnosis cost?

We provide transparent pricing before any work begins. Our call-out and diagnosis fee covers a full inspection of your system, and we'll always explain the cost upfront so there are no surprises. Contact us for current rates.

Can you carry out the repair on the same visit?

In many cases, yes. If the fault is straightforward and we have the necessary parts, we'll aim to carry out the repair on the same visit. For more complex issues or parts that need to be ordered, we'll arrange a follow-up appointment at a time that suits you.

My boiler keeps locking out — what could be causing it?

Boiler lockouts can be caused by a number of issues including low water pressure, a faulty ignition, a blocked condensate pipe, or a failing component such as a pump or heat exchanger. Our engineers will read the error code and carry out a full inspection to identify the exact cause.

Some of my radiators are cold — is that a fault?

Cold radiators, particularly those that are cold at the top, are often caused by trapped air and can be resolved by bleeding. Cold spots at the bottom, however, may indicate sludge build-up requiring a powerflush. If multiple radiators are affected, it could point to a pump or valve issue — our engineers will diagnose the exact cause.

How quickly can you attend for a fault diagnosis?

We aim to attend as quickly as possible, often within 24–48 hours for non-emergency faults. For urgent issues such as no heating or hot water, we offer emergency call-outs and will do our best to attend on the same day.

Do I need a fault diagnosis before a repair?

Yes — accurate diagnosis is essential before any repair work begins. Attempting a repair without properly identifying the root cause can result in the same fault recurring or additional damage being caused. Our structured diagnostic process ensures the right fix is carried out first time.
