From diagnosis to repair

The engineer checks the fault and explains what can be repaired during the visit. A return visit may be needed for parts or specialist work. We record the findings and the next steps.

Your questions

When can you visit?

We work from booked diary slots. Call for urgent help or send an enquiry. The office will confirm availability, access and the price before a visit.

What should I send with my enquiry?

Your postcode, a short description and any fault code are useful. If safe, add a photo of the appliance and its model label. Do not remove covers or touch wiring to take a photo.

Does an enquiry confirm an appointment?

No. Our office must confirm the diary slot and charges with you first.
