Water-Zone Compliance – We strictly adhere to Section 701 of BS 7671 regulations, ensuring all bathroom switches, lights, and shaver points are installed at the correct safe distance from water sources.
IP-Rated Lighting – Installation of moisture-protected (IP44/IP65) LED downlights and decorative fixtures designed to withstand steam and humidity in Blackburn bathrooms.
High-Load Kitchen Circuits – Dedicated wiring for heavy-draw appliances like electric hobs, double ovens, and integrated dishwashers to prevent circuit overloading and nuisance tripping.
LED Task & Ambient Lighting – Professionally installed under-cabinet LED strips and plinth lighting that enhance both the functionality and aesthetic value of your kitchen.
Certified Steam Extraction – High-performance extraction systems for kitchens and bathrooms to prevent mould growth and condensation, fully integrated into your existing electrics.
01
We map out the strict electrical safety zones in your bathroom, identifying Zone 0, Zone 1, and Zone 2 areas. This is the critical first step to ensure every planned fixture, light, and shaver point is legally and safely placed.
02
Kitchens demand huge power. We calculate the simultaneous load of your planned hob, double oven, dishwasher, and microwave. We then design the dedicated circuits and select the correct cable thickness to ensure your consumer unit is never overloaded.
03
We install with a zero-tolerance approach to safety in your Blackburn home. Our team uses corrosion-resistant components and professional-grade waterproof seals for every junction box, IP-rated downlight, and splashback socket.
04
Before making the circuits live, we perform rigorous BS 7671 verification. This includes essential insulation resistance tests and RCD trip time testing, leaving you with a safe, fully compliant, and certified property.







The UK wiring regulations divide bathrooms into Zones 0, 1, and 2 based on their proximity to water. Each zone requires specific "IP-rated" (Ingress Protection) fixtures to prevent moisture from entering electrical components. We ensure every light and switch we install is correctly rated for its specific zone.
No. Standard 13A plug sockets are generally prohibited in UK bathrooms unless they can be fitted at least 3 metres away from the edge of the bath or shower—which is impossible in most Blackburn homes. We install compliant shaver sockets that use isolation transformers for safety.
Appliances like electric hobs, ovens, and dishwashers pull a high amount of current. If they share a circuit with other outlets, you’ll constantly deal with tripped breakers. We install dedicated "radial" circuits to ensure your high-load appliances run safely and independently.
Yes. Lights installed directly above a shower (Zone 1) must be at least IP44 rated, though we typically recommend IP65 (jet-proof) for total peace of mind. These units are sealed to prevent steam and spray from causing a short circuit or corrosion.
Absolutely. In fact, it’s a building regulation requirement. We install high-extraction fans that can be wired to your light switch with a "timer delay," ensuring steam is cleared even after you leave the room, preventing mould and dampness.
Standard "rocker" switches are not permitted inside a bathroom due to the risk of wet hands touching live components. We replace these with ceiling-mounted pull-cords or install the switch outside the bathroom door to maintain full 18th Edition compliance.
