Standards & equipment we use
Every installation across Tonbridge and Maidstone is carried out to BS 7671 18th Edition wiring regulations (including the latest amendments), using calibrated Megger multifunction testers to verify insulation resistance, earth loop impedance, and RCD trip times on every circuit before sign-off. Consumer units are fitted with RCBOs or RCDs for additional shock and fire protection, and cabling is selected and sized (typically twin and earth or SWA for external runs) according to the load each circuit carries. As a NICEIC Approved Contractor, all installation work is self-certified under the Part P Building Regulations scheme, meaning no separate council building control sign-off is needed for most domestic installation work.

What is electrical installation?
Electrical installation covers any new electrical work fitted into a property rather than the repair of existing wiring. This includes running new circuits, fitting a new consumer unit (fuse box), wiring sockets and lighting for an extension or loft conversion, and installing dedicated circuits for showers, cookers, or EV charge points.
How an electrical installation works?
A qualified electrician plans the circuit layout, calculates the load the property needs, and runs new cabling through walls, floors, and ceilings using methods that meet current wiring regulations. Every new circuit is protected by the consumer unit and tested before it's handed over, so homeowners and landlords in Tonbridge and Maidstone get a system that's safe from day one, not just at the point of sign-off.
Why does this matter?
Many homes in Tonbridge, particularly the Victorian terraces near the town centre and the River Medway, and in Maidstone's older neighbourhoods around the town centre, were wired decades ago for far less electrical demand than modern households place on them. Adding an extension, a new kitchen, or an EV charger to an outdated system without a proper installation can overload circuits and create a genuine fire risk. For landlords, a compliant installation also supports the Electrical Installation Condition Report (EICR) required for rental properties, and every job comes with a signed certificate as proof of compliance for insurers, buyers, and letting agents.

How it works
1. Free quote & site visit
An electrician visits the property to assess the existing wiring, work out the load the new installation needs to support, and discuss what's being added, whether that's a new kitchen circuit, an extension, or a full rewire. A written, no-obligation quote follows the visit.
2. Installation plan agreed
The electrician confirms the circuit layout, consumer unit requirements, and cabling routes with the homeowner or landlord, so there are no surprises once work starts on site.
3. Work carried out
Cabling is run through walls, floors, and ceilings, back boxes are fitted for sockets, switches, and light fittings, and the consumer unit is connected. On extensions and refurbishments this is scheduled around plastering and decorating so the property stays livable.
4. Testing & certification
Every new circuit is tested against BS 7671 wiring regulations using calibrated Megger test equipment, and a signed Electrical Installation Certificate is issued confirming the work is safe and compliant.

What affects the cost of an electrical installation?
The cost of an electrical installation depends on the scope of the work rather than a single flat rate. The main factors are:
- Number of new circuits — a single socket circuit costs far less to add than a full rewire with a dozen new circuits.
- Consumer unit condition — whether the existing consumer unit can be reused or needs replacing with a new RCBO unit.
- Access to the property — solid walls and floors take longer to chase and reinstate than a stud wall or an unfinished extension.
- Property size and age — larger and older properties, common around West Malling’s village centre, often need more cable runs and more careful routing around existing structures.
- Urgency — same-week or emergency bookings can affect scheduling and cost compared to a planned installation booked in advance.
- Additional certification needs — landlords requiring an EICR alongside the installation add inspection time to the job.
A free site survey is the only way to give an accurate figure, since two properties of the same size can need very different amounts of work depending on their existing wiring.
Why landlords in Tonbridge and Maidstone need this
Landlords letting property in Tonbridge, Maidstone, or nearby Medway are legally required to hold a valid Electrical Installation Condition Report, and an outdated or unrecorded installation is one of the most common reasons a rental property fails that check. A documented, certified installation gives landlords a paper trail that satisfies both the EICR requirement and any insurance conditions tied to the property.
Why local matters for this service
Tonbridge’s housing stock, from Victorian terraces near the High Street to newer developments further out, sits alongside Maidstone’s mix of town centre period properties and estates around Bearsted and the ring road. An electrician who works across this mix of property types understands how to route new cabling through original walls without unnecessary disruption, and knows which areas typically have older, unmodernised wiring that needs particular care during a first fix.
Standards and methods used
Every installation follows BS 7671 18th Edition wiring regulations, using RCBO-protected consumer units, calibrated Megger test equipment, and Part P self-certification, so the finished work is both safe and legally compliant without extra council sign-off.
