What's Included in Our Extension Service

A complete electrical package for your home extension — from cable routing and circuit design to final testing and certification

First-Fix & Second-Fix

All cabling routed before plastering (first-fix), then sockets, switches, and fittings installed after decoration (second-fix). We schedule around your builder to keep the project on track.

Lighting Design

Recessed downlights, pendant fittings, wall lights, and dimmer controls tailored to each room in your extension. We design the layout for the best balance of task and ambient lighting.

Comprehensive Socket Layout

Generous socket provision placed at ergonomic heights and positions. USB sockets, TV points, and data outlets included where needed so you’re not relying on extension leads.

Consumer Unit Integration

New circuits connected to your existing consumer unit or a new sub-board installed for the extension. We ensure adequate capacity and full RCD protection for every new circuit.

Smoke & Heat Alarms

Building Regulations require interlinked smoke detection in all new habitable rooms. We install mains-powered alarms linked to your existing system for whole-house coverage.

Testing & Certification

Comprehensive testing of every circuit, an Electrical Installation Certificate, and Building Control notification – all included as standard so your extension is fully signed off.
