- Small repair visits
- From £85 including VAT Call-out, assessment and first-visit labour for a small, straightforward fault where possible.
- 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.
Repeated tripping is a reason to have the fault investigated, not to keep resetting the protection. Tell us what loses power and when it happens. An electrician can assess the circuit and distinguish possible equipment faults from installation problems.

Your repair question, answered
My fuse box keeps tripping. Do I need an electrician?
A recurring trip calls for fault finding, rather than assuming the fuse box needs replacement. Tell us what was running and which lights or sockets lost power. Do not keep resetting a circuit that trips again. Burning smells, smoke or water near electrics need urgent safety action.
The work, explained
What the visit can include
- Review the tripping pattern and affected circuit.
- Carry out appropriate fault-finding checks.
- Explain the findings and quote the necessary repair.
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.

What to include in your enquiry
- Note what was in use when the circuit tripped, if known.
- Describe any recent electrical work or water leak.
- Keep the consumer unit accessible without removing its cover.

About neighbourhoods and postcode matching
August 2026 ONS postcode data identifies boroughs sharing an outward district. Named centres use London Plan references; neighbourhood postcode examples use local address sources. Neither defines an exact neighbourhood boundary. Even a full postcode entered here is matched only by its first part.
Where a dedicated local service guide is available, we link to it. Other places lead to the relevant borough guide with your selected area carried into the enquiry. Your full repair address is needed when arranging attendance.

Questions about electricians & electrical repairs
Does a tripping circuit mean I need a new fuse box?
Not automatically. The protection may be responding to a fault elsewhere. The electrician needs to investigate before recommending component replacement or a consumer-unit upgrade.
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 fuse box tripping: electrical fault finding 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.
Do you cover all of London?
Yes. We cover all 32 London boroughs and the City of London. Select a borough below or include your full postcode when requesting a quote. The appointment depends on the required work and available specialist.
