Partial Rewiring in Kent
NICEIC-approved partial rewires for individual rooms, circuits and extensions across Kent, based in West Malling.
Partial rewiring is the replacement of the wiring in a specific part of a property, such as a single room, a kitchen circuit, or an extension, rather than the whole house. Across Kent, this is often the right option when an EICR flags a fault in one particular area, or when a homeowner is renovating a kitchen or adding an extension and the rest of the property’s wiring is still in good condition.

Standards & equipment we use
Every partial rewire across Kent follows BS 7671 18th Edition wiring regulations, with new circuits tested using calibrated Megger multifunction testers before handover. Where the existing consumer unit has spare ways, new circuits are connected there and protected with an appropriately rated RCBO. Where it doesn’t, the electrician assesses whether the consumer unit needs a small upgrade to accommodate the extra load safely. Cabling is selected and sized for the circuit, typically twin and earth for standard socket and lighting circuits, or a heavier gauge cable for a dedicated cooker or shower circuit. As a NICEIC Approved Contractor, all partial rewiring work is self-certified under the Part P Building Regulations scheme.
What does partial rewiring involve?
How a partial rewire is carried out
A partial rewire replaces the cabling and circuits in the affected area only, whether that's a single room, a kitchen, or a new extension, while leaving the rest of the property's wiring untouched. The electrician isolates the relevant circuits at the consumer unit, removes the old cabling, and runs new cable through the walls, floor, or ceiling of that area. Where the existing consumer unit has spare capacity, the new circuits are connected there. Where it doesn't, additional protection such as a new RCBO may be fitted to cover the extra load.
When does a partial rewire make sense?
Not every fault or renovation needs a full house rewire. If an EICR on a property in Maidstone or Tonbridge flags an issue confined to one circuit, or a kitchen extension needs new sockets and a dedicated cooker circuit, a partial rewire deals with exactly that area without disturbing rooms that don't need any work. This keeps disruption and cost lower than a full rewire, while still bringing the affected part of the property up to current BS 7671 wiring regulations. For landlords with an older rental property anywhere in Kent, a partial rewire can also be a practical first step if only certain circuits fail an inspection.

How it works
1. Free Site Survey & Written Quote
An electrician assesses the affected room, circuit, or extension, checks the existing consumer unit's spare capacity, and provides a written, itemised quote before work is booked.
2. Isolation & Cable Removal
The relevant circuits are safely isolated at the consumer unit, and any old or faulty cabling in the affected area is removed.
3. New Cabling Installed
New cable is run through the walls, floor, or ceiling of the affected room or extension, with sockets, switches, and light fittings positioned as agreed.
4. Connection & Testing
The new circuits are connected at the consumer unit and tested using calibrated Megger multifunction test equipment, checking insulation resistance, earth loop impedance, and RCD trip times.
5. Certification
A signed Electrical Installation Certificate is issued, confirming the rewired area meets BS 7671 wiring regulations and is safe to use.

- Careful isolation so only the agreed circuits are touched
- Electrical Installation Certificate issued within 48 hours
What affects the cost of a partial rewire?
The cost of a partial rewire depends on the scope of the affected area rather than a single flat rate. The main factors are:
- Size of the area — rewiring a single room costs less than rewiring a full kitchen extension with multiple new circuits.
- Number of new circuits — a straightforward socket circuit is quicker to fit than a dedicated cooker or shower circuit.
- Consumer unit capacity — whether the existing consumer unit has spare ways or needs additional protection fitted to take the new circuits.
- Access to the area — solid walls and floors, common in older West Malling properties, take longer to chase and reinstate than a stud wall or an unfinished extension.
- Redecoration allowance — chasing walls for new cabling will disturb plaster and paintwork in the affected area.
- Fault complexity — if the rewire is following an EICR fault, tracing the exact extent of the affected circuit can add time before work starts.
A free site survey is the only way to give an accurate figure, since the scope of a partial rewire varies significantly from one property to the next.
Why landlords in Kent need this
Landlords in Maidstone, Tonbridge, and Medway sometimes find that only certain circuits fail an EICR, rather than the whole property’s wiring. A partial rewire addresses those specific circuits directly, giving landlords a cost-effective route back to compliance without the time and disruption of rewiring rooms that already meet current standards.
Why local matters for this service
Kent has a mix of period cottages, converted properties, and newer extensions, from the villages near West Malling to newer developments like Kings Hill, and it’s often the extension or a single renovated room that needs new wiring while the rest of the property is unaffected. An electrician familiar with this mix understands how to isolate and rewire one area without disturbing circuits serving the rest of the home.
Standards and methods used
Every partial rewire follows BS 7671 18th Edition wiring regulations, uses calibrated Megger test equipment to confirm the new circuits are safe, and is self-certified under Part P, so the finished work is fully compliant without extra council sign-off.

Frequently asked questions
A partial rewire replaces the wiring in one room, circuit, or extension, while the rest of the property’s wiring is left as it is. A full rewire replaces every circuit and the consumer unit throughout the whole property.
If an EICR flags a fault confined to one circuit, or you’re renovating a single room or adding an extension while the rest of the property’s wiring is in good condition, a partial rewire is usually enough.
No. The affected circuits are isolated at the consumer unit before work starts, so the rest of the property’s power supply is unaffected during the job.
A single room or circuit is often completed within a day, while a kitchen extension with several new circuits typically takes 2 to 3 days.
Yes. Partial rewires are carried out across West Malling, Maidstone, Tonbridge, Medway, Sevenoaks, and the surrounding areas, for both homeowners and landlords.
