Find the right repair in Merton
You do not need to know the technical name. Choose the description that fits, then see the repair options and what to include in your enquiry.
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.
A plug socket has stopped working. Can you replace it?
First establish whether the fault is at that socket, an appliance or the circuit supplying it. Tell us if other sockets have also stopped working. We arrange the relevant checks and any suitable repair; replacement of the faceplate alone may not resolve a supply fault.
My lights flicker or keep going out. Which service do I need?
Choose lighting fault finding and describe whether one fitting, a room or several rooms are affected. Include the bulb or fitting type and whether a dimmer is involved. This helps distinguish a fitting or compatibility problem from a fault requiring wider circuit checks.
The work, explained
How we can help
- Socket and switch repairs or replacement.
- Lighting faults, tripping circuits and electrical diagnosis.
- Extractor fans and outside lighting, with suitable components and testing.
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.
Help us plan your visit

- Describe affected rooms, equipment and any visible error or tripping pattern without opening covers.
- Include access to the consumer unit and who can approve a planned interruption to the supply.

Electricians & electrical repairs in Merton
Planning the repair at your Merton property
For Wimbledon or Mitcham work, show the fitting or surface and its position within the room. Faults behind finished panels and defects returning after repair need a clear history and access plan.
Drivers, fans and wiring behind finishes
For a lighting or extractor fault, share product information and the location of any known access hatch. The electrician checks the compatible components and installation. Opening ceilings or disturbing finishes requires an agreed approach.
Intermittent tripping or flickering
Record when the fault occurs and what was in use, without repeatedly resetting equipment. Include previous electrical findings and recent changes. Fault finding needs to establish the cause before replacement fittings or further work are selected.
Example work, explained
Investigating a faulty socket
- The problem
- A socket is unreliable, damaged or no longer supplies power. The fault can be at the fitting or elsewhere on the circuit.
- The work involved
- The electrician investigates the fault, safely isolates as required and repairs the connection or replaces a suitable fitting where appropriate. Circuit defects are explained before extra work.
- Checks and next steps
- Carry out the electrical checks appropriate to the work and explain the findings and any further action needed before the affected installation returns to use.

Help us prepare the right visit
Send a wider room view, available product references and details of previous work. Include any visible damage needing later making good.
Can a new LED fitting use my existing transformer?
Compatibility must be checked against the fitting, driver, dimmer and installation. A similar-looking lamp or matching connector alone is not enough to choose the replacement.
Will replacing the breaker stop repeated tripping?
Not necessarily. Tripping can indicate a fault elsewhere. The electrician needs to investigate the circuit and connected equipment before proposing the appropriate repair.

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.
Postcode districts and borough boundaries

These are borough-wide postcode associations. A district can cross boroughs and include other neighbourhoods or addresses outside London. Even a full postcode shown in the finder gives district suggestions, not an address check. Give the street address and full postcode when booking.
