When something goes wrong with the electrics in your home or business, calling an electrician can seem straightforward. But a professional electrician company in London can do much more than replace a faulty socket or investigate why the lights have stopped working.
A qualified electrical company can help with everything from electrical safety inspections and fault finding to rewiring, consumer unit upgrades, lighting installations, EV chargers, smart home technology and commercial electrical systems.
Put simply, a professional electrician company installs, tests, repairs and maintains electrical systems to help keep homes and businesses safe, compliant and working reliably.
At Certified Electricians London, we provide a comprehensive range of electrical services across the capital and the surrounding areas. Our experienced electricians work with homeowners, landlords, businesses and property professionals on everything from minor electrical repairs to more extensive installations and upgrades.
What Can an Electrician Do for Your Home or Business?
A professional electrician company provides specialist services relating to the electrical installation within a property.
This may include installing new electrical equipment, repairing faults, inspecting existing wiring, upgrading electrical systems and making sure electrical work is tested correctly.
Typical electrical services can include:
- Electrical repairs and fault finding
- Electrical Installation Condition Reports (EICRs)
- Consumer unit upgrades
- Full and partial rewiring
- Lighting installation
- Additional sockets and switches
- EV charger installation
- Smart home installations
- Fire alarm systems
- Emergency lighting
- PAT testing
- Electrical maintenance
- Emergency electrical repairs
The exact work required will depend on the type, age and use of the property.
At Certified Electricians London, we work across both domestic and commercial electrical installations, allowing us to assist with anything from a problem in a London flat to electrical work within an office, retail unit or other commercial premises.
Do Electricians Repair Electrical Faults?
Yes, electrical fault finding and repairs are a major part of the work carried out by professional electricians.
Electrical problems are not always obvious.
A socket that has stopped working could be caused by the socket itself, the circuit supplying it or another problem within the electrical installation. Similarly, a circuit breaker that repeatedly trips may indicate an overloaded circuit, faulty equipment or an electrical fault requiring investigation.
Common signs that you may need an electrician include:
- Circuit breakers repeatedly tripping
- Flickering or dimming lights
- Sockets or switches that no longer work
- Burning smells around electrical equipment
- Unusual buzzing or crackling
- Discoloured sockets or switches
- Partial or complete power loss
- Electrical equipment repeatedly causing a circuit to trip
Electrical faults should not simply be ignored, particularly when they recur.
At Certified Electricians London, we can investigate electrical problems, identify the likely cause and recommend the appropriate repair rather than simply replacing components without establishing why the fault occurred.
What Is an EICR and When Might You Need One?
An Electrical Installation Condition Report, usually shortened to EICR, is an inspection and test of an existing electrical installation.
It helps establish whether the installation is in a satisfactory condition for continued use and can identify defects, deterioration or areas where further investigation may be required.
An EICR can be particularly useful if you:
- Are a landlord
- Are buying a property
- Have recently moved into an older home
- Are planning significant renovations
- Have concerns about existing wiring
- Do not know when the electrics were last inspected
At Certified Electricians London, our qualified electricians carry out EICRs and provide clear information about the condition of the electrical installation.
If issues are identified, we can also discuss the remedial electrical work that may be needed.
Regular electrical inspection can be an important part of maintaining a property, particularly where an installation is older or has been altered numerous times over the years.
Can an Electrician Replace a Consumer Unit?
Yes. A qualified electrician can assess and replace an outdated consumer unit where an upgrade is appropriate.
The consumer unit is a critical part of a home's electrical installation. It distributes electricity between circuits and houses protective devices designed to respond when faults occur.
Older properties may still have ageing fuse boxes or consumer units that lack some of the protection found in more modern installations.
However, replacing a consumer unit should not simply be treated as swapping one box for another.
Before an upgrade, the wider electrical installation may need to be assessed so that existing defects can be identified. Once installed, the new consumer unit and associated electrical work must also be correctly inspected and tested.
We carry out consumer unit upgrades in London and can advise customers on the most appropriate solution for their property.
When Does a Property Need Rewiring?
Not every older property needs a complete rewire.
However, electrical wiring does not last indefinitely, and properties that have been altered repeatedly over many decades can sometimes contain a mixture of electrical installations from different periods.
Possible warning signs include damaged or deteriorated wiring, recurring electrical faults, outdated components or an installation that is no longer suitable for the way the property is being used.
Can an electrician tell whether my house needs rewiring?
Yes. An electrician can inspect and test the electrical installation to help determine its condition and whether repair, partial upgrading or more extensive rewiring is appropriate.
This is usually a much better approach than assuming an older property automatically needs to be completely rewired.
At Certified Electricians London, we can assess existing electrical systems and provide advice based on the condition of the installation and the work you are planning.
Where rewiring is required, careful planning is particularly important during renovations because the electrical layout can be designed around the way the property will actually be used.
What Electrical Work Can Be Done During a Home Renovation?
Renovating a property is one of the best times to reconsider its electrical installation.
Rather than simply putting sockets and lights back where they have always been, a professional electrician can help plan an electrical system around modern requirements.
This could include:
- Additional power sockets
- USB or modern charging outlets
- New lighting circuits
- Kitchen electrical supplies
- Electric ovens and hobs
- Bathroom lighting
- Outdoor electrics
- Underfloor heating
- Smart thermostats
- Video doorbells
- Smart home equipment
- EV charging
- New consumer units
Planning electrical work early can also reduce the need to disturb newly decorated surfaces later.
If you are extending, refurbishing or renovating a London property, we can work with you to understand what you need from the electrical installation before the work is completed.
Can an Electrician Install an EV Charger?
Yes. Appropriately qualified electricians can install domestic and commercial electric vehicle charging equipment.
EV charger installation involves more than mounting a charger to a wall.
The existing electrical installation needs to be considered, including whether it is suitable for the additional electrical load. The location of the charger, cable route and appropriate electrical protection also need to form part of the installation plan.
At Certified Electricians London, we install EV chargers for homes and commercial properties, helping customers add convenient charging facilities while ensuring the electrical installation is properly considered.
For businesses, EV charging can also form part of a wider electrical upgrade alongside lighting, power distribution and other infrastructure.
What Can an Electrician Do to Improve a Home's Lighting?
Lighting can completely change the appearance and practicality of a room, but good lighting design is about more than choosing attractive fittings.
An electrician can help with:
- Ceiling lights
- Spotlights and downlights
- LED lighting
- Wall lights
- Outdoor lighting
- Garden lighting
- Additional lighting circuits
- Dimmer switches
- Smart lighting controls
- Replacement switches
Different parts of the home have different requirements, and certain locations require additional consideration when electrical equipment is selected and installed.
At Certified Electricians London, we install lighting as part of both standalone projects and larger renovation work. We can also advise on practical positioning and suitable electrical solutions before the fittings are installed.
Do Electrician Companies Work With Smart Home Technology?
Increasingly, yes. Modern electrical work often overlaps with smart home technology, particularly as homeowners look for greater control over lighting, heating, security and energy use.
Smart electrical installations might include:
- Smart lighting
- Connected thermostats
- Video doorbells
- Smart switches
- Automated controls
- Security equipment
One advantage of involving an electrician early is that the power supplies, switches and cabling required for the technology can be considered as part of the wider installation.
We install a range of smart home electrical solutions and can integrate them into wider renovation and electrical upgrade projects.
What Does a Commercial Electrician Company Do?
Commercial electrical work involves installations within workplaces and other business premises.
A commercial electrician in London may work in offices, shops, public-sector buildings, industrial premises and other commercial environments.
Services can include:
- Electrical installation and maintenance
- EICRs
- PAT testing
- Lighting installations
- Emergency lighting
- Fire alarm systems
- Consumer unit and distribution upgrades
- CCTV and intercom systems
- EV charger installation
- Electrical fault finding
- Planned electrical upgrades
Businesses often have an additional priority: disruption.
Electrical work may need to be carefully planned so that essential operations can continue wherever practical.
At Certified Electricians London, we work with businesses to provide electrical installations, testing, repairs and maintenance while considering the operational needs of the premises.
What Is the Difference Between a Domestic and Commercial Electrician?
Domestic electricians primarily work in homes, while commercial electricians work within business and other non-domestic premises.
There is considerable overlap in the skills involved, but the scale, equipment, electrical loads and operational requirements can differ.
A domestic electrician might be installing sockets, replacing a consumer unit or rewiring a house.
A commercial electrician could be maintaining the electrics in an office, installing emergency lighting, carrying out PAT testing or upgrading electrical systems within a shop.
At Certified Electricians London, we provide both domestic and commercial electrical services, meaning customers can use us for a broad range of electrical requirements.
Why Does NICEIC Registration Matter?
Choosing a professional electrical company is not just about finding somebody who can physically complete the work.
Competence, inspection, testing, certification and compliance all matter.
Our electricians are NICEIC registered, and safety and compliance are central to the way we work.
Electrical installations should be carried out by people with the appropriate competence for the work involved. Using a professional electrician also means there is somebody who can properly inspect and test completed work and provide relevant certification where required.
This becomes particularly important for major electrical work such as rewiring, consumer unit replacements and new electrical installations.
What Happens When You Book a Professional Electrician?
The process will vary depending on the job, but a professional electrical company should first understand what you need.
For a straightforward installation, this may simply involve discussing the required work and arranging an appointment.
For larger projects, an electrician may need to assess the property before providing an appropriate quotation.
Once the work begins, the electrician should complete the installation or repair safely, carry out the necessary testing and explain any relevant findings or recommendations.
At Certified Electricians London, we believe communication is an important part of good electrical work. We aim to provide clear information about the work required and transparent quotations so customers understand what is being proposed.
When Should You Call an Emergency Electrician?
Some electrical problems can wait for a planned appointment. Others require more urgent professional attention.
You should seek professional assistance if there are signs of an immediate electrical safety issue, such as burning, significant overheating, exposed live electrical components or serious unexpected power problems.
If it is safe to do so, avoid using equipment or circuits that appear to be affected until the problem has been properly assessed.
We provide emergency electrical services in London for urgent problems including power loss, damaged wiring and electrical faults.
The priority is to identify the problem and make the installation safe before determining whether further remedial work is needed.
