Our Work 

# Real Problems. Permanent Solutions. 

Every project below represents a real challenge we solved for a real client. No stock photos, no generic descriptions — just documented examples of how we work.

## Complete Victorian Terrace Rewire

South Croydon, CR2

[House Rewiring →](/services/house-rewiring)

### Challenge

A 4-bedroom Victorian terrace with original 1920s rubber-sheathed wiring throughout. The homeowner reported frequent circuit trips, warm socket faceplates, and a burning smell from the consumer unit.

### Solution

Full property rewire including 12 new circuits, dual-RCD consumer unit, supplementary bonding, and smoke/heat detection. Cables routed through existing voids to minimise redecoration. Completed in 5 working days.

### Result

Property now meets current BS 7671 standards with full certification. Insurance renewed without issue. No further electrical faults reported.

## Emergency Power Restoration

Bromley, BR1

[Emergency Repair →](/services/emergency-repairs)

### Challenge

Complete power failure at 1am in a family home with young children. Main incoming fuse had blown and the consumer unit showed signs of overheating.

### Solution

Engineer arrived within 30 minutes. Isolated the fault, replaced the damaged main fuse holder, and identified the root cause — a deteriorated neutral connection. Temporary restoration within 45 minutes, permanent repair completed the following morning.

### Result

Power restored safely same night. Follow-up visit completed the permanent repair and a full consumer unit upgrade was scheduled.

## Multi-Property EICR Programme

Streatham & Tooting, SW16/SW17

[EICR Testing →](/services/eicr-testing)

### Challenge

A landlord with 8 rental properties across Streatham and Tooting needed all EICRs completed within 3 weeks to meet tenancy renewal deadlines.

### Solution

Scheduled 2 inspections per day across 4 days. Identified remedial work required at 3 properties. Completed all repairs within the following week. All certificates issued within the 3-week deadline.

### Result

Full compliance achieved across all 8 properties. Ongoing annual schedule established for portfolio management.

## Whole-Home Smart Lighting System

Dulwich, SE21

[Smart Home →](/services/smart-home)

### Challenge

A 5-bedroom Dulwich Village home wanted integrated smart lighting across all rooms, garden, and outbuilding — controllable via app and voice with scene presets for entertaining.

### Solution

Installed Lutron Caseta system with 42 smart switches, outdoor-rated controllers for garden lighting, and integration with existing Sonos and home automation. Programmed 8 scene presets. All wiring concealed within existing routes.

### Result

Complete lighting control from phone or voice. Energy consumption reduced by approximately 40%. Client describes it as 'transformative'.

## Commercial Kitchen Electrical Fit-Out

Tooting, SW17

[Commercial →](/services/commercial-electrical)

### Challenge

A new restaurant required a complete electrical fit-out including commercial extraction, 3-phase cooking equipment, walk-in refrigeration, and front-of-house lighting — all within a tight 2-week build schedule.

### Solution

Designed and installed a new 3-phase distribution board, dedicated circuits for all commercial equipment, LED lighting throughout, emergency lighting, and fire alarm integration. Worked alongside other trades to meet the deadline.

### Result

Restaurant opened on schedule. Passed environmental health electrical inspection first time. No issues since opening.

## Rural Farmhouse EV Charger & Rewire

Edenbridge, TN8

[EV Charger + Rewiring →](/services/ev-charger-installation)

### Challenge

A converted farmhouse with 1970s wiring needed a partial rewire to support an EV charger installation. The existing supply was borderline for the additional load.

### Solution

Upgraded the consumer unit, added a dedicated 32A circuit for the EV charger via SWA cable to the detached garage, and rewired the kitchen and utility room. Liaised with the DNO regarding supply capacity.

### Result

EV charger operational with full certification. Kitchen and utility room brought to current standards. OZEV grant successfully claimed.
