Electrical Services for Homes, Landlords & Businesses
Emergency Electrical Repairs
Electrical faults can happen without warning. If you have lost power, a circuit keeps tripping, you notice a burning smell or you have a damaged socket or fitting, professional fault finding can help identify and resolve the problem safely.
Our emergency electrical services cover common urgent problems such as power loss, tripping circuits, faulty sockets and damaged wiring across South West London. Contact us to discuss your fault and availability.
EICR Certificates & Electrical Inspections
An Electrical Installation Condition Report (EICR) helps identify defects and assess the condition of an electrical installation.
We provide EICR inspections and certificates for homeowners, landlords, rental properties and businesses. If you need an electrical safety inspection for a property in Tooting, find out more about our EICR certificates in Tooting.
Fuse Board & Consumer Unit Upgrades
Older consumer units may not provide the protection required by modern electrical installations.
We assess existing consumer units and install suitable modern systems, including appropriate protective devices and certification. Find out more about our electrical installation and upgrade services.
House Rewiring
Older properties may require full or partial rewiring where existing wiring is damaged, outdated or no longer suitable for modern electrical demands.
BuildSpark provides full and partial house rewiring, including testing and certification following completed works. For properties in Tooting and nearby areas, see our house rewiring service in Tooting.
Electrical Fault Finding
If sockets stop working, lights flicker or circuits repeatedly trip, identifying the underlying cause is essential.
Our electricians can investigate electrical faults and recommend the appropriate repair rather than simply treating the symptom. You can find out more about our electrical fault finding and repair services.

We also provide fire alarm and interlinked alarm installations for non-domestic and commercial properties, with systems selected according to the property and its requirements.
