BuildSpark

Based in Tooting, BuildSpark handles electrical work for homes, rental properties, and commercial premises across southwest London. Its services range from repairs and inspections to new installations, including everything from tracing a fault to rewiring a house. BuildSpark is the trading name of Buildonly Ltd.

Electrical fault response is one of its core services. The company lists work for power outages, tripping circuits, damaged outlets, faulty wiring, and other problems that call for diagnosis. The job starts by identifying the cause; the work may then involve a targeted repair or steps to address risks.

To assess an installation, the team performs EICR inspections—Electrical Installation Condition Reports—for homes, rental properties, and commercial premises. It also carries out remedial work that may follow an unsatisfactory inspection. The service is relevant to landlords and letting agents who need to review electrical safety at their properties.

Upgrades include replacing consumer units, adding surge protection, improving lighting, and completing partial or full rewires. BuildSpark also installs residential and commercial EV chargers. Each project depends on the property's condition and the customer's needs; the company says it provides the appropriate certification for installations it completes.

Fire safety is another service line. As an Aico Approved Installer, the company installs smoke, heat, and carbon monoxide alarms, including wireless interconnected systems. Its landlord services also include portable appliance testing, inspections, remedial work, and alarm solutions for shared housing and commercial buildings.

The website also describes emergency lighting, maintenance, inspections, and commercial electrical installations. BuildSpark lists NAPIT approval, City & Guilds qualifications, and insurance. It also advertises a 12-month workmanship warranty and transparent pricing, with quotes based on the work requested.

Its service area includes Tooting, Balham, Clapham, Wimbledon, Earlsfield, Wandsworth, Streatham, Mitcham, Battersea, Putney, and nearby parts of southwest London. The published address is in Tooting, while work is carried out at properties throughout its coverage area. Regular hours include weekdays and weekends; the company advertises 24/7 availability for electrical emergencies.

BuildSpark brings together three common needs for property owners, landlords, and businesses: fixing a fault, documenting an installation's condition, and planning an upgrade. EICR inspections, rewiring, consumer-unit replacements, alarms, and EV charging form a connected service range for properties that need modernization or a response to a specific problem.
