Kitchen & BathroomElectrical Installation
Renovation-ready electrical work designed around your project. Zone-compliant bathroom wiring, dedicated kitchen circuits, underfloor heating, and proper trade coordination — all Part P certified.
Specialist Renovation Electrics
Kitchens and bathrooms are the most electrically demanding rooms in your home. They're also the most regulated — bathrooms because water and electricity share the same space, kitchens because of the heavy loads from modern appliances.
Getting the electrics wrong during a renovation means rework, delays, failed inspections, and potentially dangerous installations. Getting them right means safety, compliance, and a result that works perfectly from day one.
What we handle during kitchen and bathroom renovations:
- Complete electrical design around your kitchen fitter's or bathroom designer's plan
- Dedicated circuits for high-draw appliances — ovens, hobs, dishwashers, washing machines
- Zone-compliant bathroom wiring with appropriate IP-rated equipment
- Extractor fan installation and wiring (humidistat and timer options)
- LED downlight installation with fire-rated enclosures
- Electric underfloor heating installation and thermostat wiring
- Shaver sockets, heated mirror connections, and towel rail circuits
- Consumer unit upgrades where existing capacity is insufficient
We work on renovation projects across our entire service area — from period property upgrades in Dulwich to modern bathroom installations in Sutton and kitchen fit-outs in Bromley.
Kitchen & Bathroom Electrical Challenges
Bathroom Zone Regulations
Bathroom electrical zones (BS 7671 Section 701) define where equipment can be installed and what protection it needs. Zone 0 (inside bath/shower) permits only SELV equipment. Zone 1 requires minimum IPX4 rating. Zone 2 requires IPX4 for luminaires. Getting this wrong creates genuine electrocution risk.
Kitchen Circuit Loading
A modern kitchen can draw 15–20kW simultaneously — oven, hob, kettle, dishwasher, washing machine. This exceeds what a single ring circuit provides. Dedicated radial circuits for each major appliance prevent overloading, tripping, and potential fire risk from overworked cables.
Trade Sequencing
Electrical first fix must happen at the right point in the renovation timeline — after demolition and before plastering/tiling. Second fix comes after surfaces are finished. Mistiming costs money and causes delays. We coordinate with your other trades to ensure smooth sequencing.
Older Property Challenges
Many properties in our area have outdated wiring that can't support modern kitchen or bathroom loads. Adding dedicated circuits may require a consumer unit upgrade or partial rewire. We assess this upfront so there are no surprises mid-renovation.
How We Work on Renovations
Designed to integrate seamlessly with your renovation timeline and other trades.
Survey & Plan
We visit your property, discuss your renovation plans, and assess existing electrics. We design the electrical layout around your fitter's plan.
First Fix
Cable routes installed before tiling and plastering. Junction boxes, back boxes, and supply cables positioned precisely for final fixture locations.
Coordination
We work around your other trades — plumber, tiler, kitchen fitter. Proper sequencing means no delays and no rework.
Second Fix
Sockets, switches, lighting, extractor fans, and appliance connections completed once surfaces are finished. Clean, precise installation.
Testing & Sign-Off
Full circuit testing, RCD verification, and Part P certification. Documentation for building control and your records.
Why Choose 24/7 Electrical for Renovation Projects
Renovation-experienced electricians who understand trade coordination, building timelines, and the specific demands of kitchen and bathroom work.
Zone Compliance
Bathrooms have strict electrical zones (0, 1, 2, and outside zones) under BS 7671. We specify IP-rated equipment and wiring methods appropriate for each zone.
Kitchen Expertise
Modern kitchens need dedicated circuits for ovens, hobs, dishwashers, and other high-draw appliances. We design circuits for your specific appliance layout.
Part P Certified
All notifiable bathroom and kitchen electrical work is self-certified under Part P Building Regulations. No separate building control application required.
Trade Coordination
We work alongside your builder, plumber, and fitter with proper first-fix/second-fix sequencing. No delays, no clashes, no rework.
Future-Proofed Circuits
We install sufficient circuits and capacity for current and future needs. Adding sockets later is expensive — getting it right during renovation costs nothing extra.
Renovation Scheduling
We understand renovation timelines and coordinate our visits around your other trades. First fix before plastering, second fix after tiling.
Kitchen & Bathroom Electrics FAQs
Common questions about renovation electrical work, regulations, and costs.
Signs Your Bathroom or Kitchen Electrics Need Work
Wet rooms and kitchens are where bad wiring becomes dangerous fastest. Here's what to watch.
Bathroom electrics are zone-classified for a reason. Wrong fitting, wrong zone = electric shock risk and an automatic fail on any future EICR.
- Sockets, switches or shower units are positioned in zones they shouldn't be
- Your bathroom shaver socket is the only outlet — and it's not in zone 3
- Lights flicker or buzz when the shower or extractor runs
- Your kitchen has fewer than 8 working sockets above worktop level
- Integrated appliances are plugged into multi-way adaptors behind units
- There's no dedicated cooker switch or it's discoloured / loose
- You're planning a new kitchen, bathroom or wet-room install
- Existing pull-cord switches in the bathroom are cracked or stiff

Worried About Bathroom & Kitchen Wiring Work?
These are the questions every homeowner asks before signing off a refit.
"Will the work hold up the rest of my refit?"
We coordinate first-fix and second-fix dates directly with your kitchen / bathroom fitter so the trades flow without dead time. Most refits gain a day or two from proper planning.
"How do I know it's actually safe in a bathroom?"
Every accessory is selected to the correct IP rating for its zone (IPX4 zone 1, IPX5 zone 0). The certificate lists every fitting and its zone — your insurer or future buyer can audit it.
"Can you work around new tiling without damaging it?"
Yes. We mark socket positions with the fitter before tiling, use diamond-cored holes for outlets and isolators, and never chase finished tiles unnecessarily.
"Will the work be Building Control notified?"
Yes — under our NICEIC Part P scheme. You receive an Electrical Installation Certificate and a Building Control compliance certificate within 30 days of completion.
