- Need help urgently?
- Call for availability Tell us your postcode, work required and access arrangements. Sending a form does not book attendance.
For safely accessible faults that can be resolved on the first visit. Parts, materials and further work are quoted separately for your approval. If a first-visit fix isn’t possible, the agreed visit charge still covers the call-out and assessment. We explain the fault and quote any parts, further investigation or larger repair for your approval.
A switch fault may involve the control, fitting or wiring. Tell us whether it is a standard switch, dimmer or smart control. We arrange checks and compatible repairs rather than assuming a different faceplate will solve the problem.
The work, explained
What the visit can include
- Assess the affected switching arrangement.
- Check compatibility with lamps, drivers and controls where relevant.
- Complete agreed replacement and operation checks.
Electrical work is matched to the appropriate competence. Testing, certification and any building-control notification depend on the work; these are set out in the quotation. A repair visit is not an EICR or a full rewire.

- State how many switches operate the affected light.

Questions about electricians & electrical repairs
Why does the light flicker after changing a dimmer?
Compatibility between the dimmer, lamp and driver is one possible cause, but wiring or fitting faults can also be involved. Include all known product details so the electrician can assess the system together.
Will I receive an electrical certificate?
The electrician determines the testing, certification and any notification required for the agreed work. Ask for the required documents to be included in your written scope. A small repair does not automatically include a whole-property inspection report.
How much does light-switch repair & replacement cost?
From £85 including VAT for call-out, assessment and labour to fix a small, safely accessible fault on the first visit where possible. We’ll give you the full visit price when you book. Parts and further work need a separate quote and your approval. If the repair needs more work, the visit charge still covers call-out and assessment.
