— Electrical · South London

Electrical installations across South London.

Rewires, consumer units, sockets, lighting, outdoor power, EICR reports — all electrical work carried out by individually qualified NICEIC certified subcontractors with Part P notification.

Most of our electrical work is part of a larger renovation — full house rewires during refurbishments, new circuits for kitchen and bathroom extensions, lighting plans for loft conversions, garden power runs. LMDEC project-manages every electrical installation end-to-end; all electrical work is carried out by our trusted independent subcontractors who are individually NICEIC certified, with full Part P notification and EICR reports issued for every job.

— What we do

Electrician South London — services we deliver.

Full property rewires

Complete property rewires for Victorian and Edwardian homes still running old single-core, rubber-insulated or aluminium cabling. New ring mains, lighting circuits, consumer unit, earth bonding, RCD protection, smoke detection — all to current Wiring Regulations (BS 7671). Always part of a wider refurbishment in our experience — strip-out first, rewire while walls are open, then plaster and decorate. Carried out by individually qualified NICEIC certified subcontractors with Part P notification and EICR certification issued on completion.

Sockets, switches and additional circuits

Extra double sockets, USB-C outlets, network points, dedicated circuits for ovens, induction hobs, electric showers, immersion tanks. Most modern kitchens need 6-10 new socket positions on dedicated circuits. We chase walls neatly, run cables in conduit where possible, and make good ready for plastering.

Lighting design and installation

Layered lighting plans — ambient, task, accent — for kitchens, living rooms, bathrooms and bedrooms. Recessed downlighters, wall lights, pendants, under-cabinet LED strips, and mood-lit kitchen islands. Dimmable circuits where it matters. Smart switches if you want them, but we won’t push them.

Consumer units and earthing

Old fuse boxes replaced with modern consumer units — RCD-protected circuits, surge protection, AFDD where required by latest regs. Earth bonding to gas, water and structural metalwork checked and corrected. Common upgrade for older South London properties where insurance or mortgage lenders require an EICR.

Outdoor and garden electrics

Garden lighting, outdoor sockets, power to sheds and garden offices, lighting for patios and pathways, security floodlights, IP65-rated installations. SWA armoured cable runs underground at the correct depth, RCD protection at the supply end. Common for garden outbuildings and home offices.

EICR reports and electrical safety

Electrical Installation Condition Reports for landlords (legally required every 5 years for rental properties), insurance renewals, pre-purchase surveys, and post-renovation certification. Honest, thorough assessments — Code 1, 2 or 3 reasons identified clearly, with sensible recommendations on what’s urgent and what can wait. Issued by individually qualified NICEIC certified subcontractors.

— What it costs

Electrician South London — costs 2026.

Honest ranges based on the electrical work we deliver across South London in 2025-2026. Final price depends on accessibility (cable runs through solid walls vs accessible floor voids), age of existing wiring, and whether plastering and decoration is needed after.

Single point installations

Around £90 per point for sockets, switches, light fittings and spurs — assumes accessible cable runs. Add £30-80 per point for make-good (plaster repair, decoration touch-up). Most homeowners need 5-15 new points during a refurbishment.

Consumer unit replacement

£800 – £1,400 depending on the number of circuits, surge protection, AFDD requirements, and whether earth bonding upgrades are needed. Includes new EICR certification issued by individually qualified NICEIC certified subcontractor.

Full property rewire

Two-bed flat: £3,500 – £6,000. Three-bed house: £5,500 – £9,000. Four-bed house: £8,000 – £13,000. All include a new consumer unit, full RCD protection, smoke alarms to current Wiring Regulations, and full EICR certification. Best done during a refurbishment, when walls are already being re-plastered.

EICR reports

£180 – £350 depending on property size — flat through to four-bedroom house. Includes full inspection, testing, written report, and remediation recommendations if Code 1 or Code 2 issues are found. Carried out by individually qualified NICEIC certified subcontractor.

All prices include NICEIC certification by individually qualified subcontractors, Part P notification to Building Control where required, and full make-good (plaster repair, decoration). VAT extra.

— How we work

Our electrical installation process.

Bad electrical work is the most dangerous thing a builder can leave behind. LMDEC project-manages every electrical job end-to-end. All electrical work is carried out by our trusted independent subcontractors who are individually NICEIC certified — every job ends with proper testing, signed Electrical Installation Certificate, and Part P notification to Building Control. No exceptions, no informal electrical work.

1. Site visit and survey

We assess existing installation, check consumer unit, identify potential issues (old aluminium cabling, missing earth bonding, no RCD protection, overloaded circuits), and discuss what you want added or changed.

2. Lighting and circuit design

For renovations, we plan socket and switch positions, lighting layouts, switch zones, and dedicated circuits for major appliances. Marked up on drawings so you can see exactly where everything will be before we cut a single chase.

3. Fixed-price quote

Itemised by point, by circuit, by area. Materials, labour, certification, and make-good are clearly separated. If existing wiring is in worse condition than expected, we will tell you before we cut anything.

4. First-fix and second-fix

First-fix: cable runs, back boxes, consumer unit upgrade carried out by NICEIC certified subcontractor. Then plastering and decoration are part of a wider refurbishment by LMDEC team. Second-fix: sockets, switches, light fittings, and consumer unit commissioning by NICEIC certified subcontractor.

5. Testing and certification

Insulation resistance, polarity, earth fault loop impedance, RCD operation — full testing per BS 7671. Electrical Installation Certificate issued by individually qualified NICEIC certified subcontractor; Part P notification submitted to local Building Control; EICR provided upon request. Two-year LMDEC workmanship warranty on the wider project.

Fixed-price quotes, make-good included. The price you see covers labour, materials, NICEIC certification, plaster repair, and decoration touch-up. No “the painter will need to come back” surprises.

£2 million Public Liability insurance, two-year LMDEC workmanship warranty. Full Part P notification handled with Building Control where required.
