🔒 We never share your details with anyone
After years of working on properties across Hertfordshire and Essex, these are the warning signs we see again and again. If you've spotted any of these in your home, get in touch — we'll come and take a proper look.
If you've still got round-pin sockets or cloth-insulated wiring, your electrics are likely pre-1960s and well past their safe lifespan.
The old "wylex" wooden fuseboxes are a tell-tale sign. They don't meet modern safety standards and offer no RCD protection.
Sockets that feel warm to the touch, or have browning around the pin holes, suggest dangerous loose connections behind the wall.
If your fuses keep blowing or breakers keep tripping, it's usually a sign of overloaded or deteriorating wiring underneath.
A "fishy" smell coming from sockets or your fusebox is the smell of overheating plastic — never ignore this one.
If lights dim when the kettle or shower comes on, your wiring may not be handling modern electrical demand.
One of the most common (and overlooked) warning signs we see on older rewires. Watch Jamie explain what green goo is, what causes it, and why it matters.
Transcript: "Just got a short little video for you here to show you green goo. So we've got green goo in this light switch. If your home was wired between the 1960s and 1980s and you're getting flickering lights or unexplained tripping, it's probably a good idea to get an EICR carried out to see if your house is affected by green goo. It's caused by heat breakdown — a chemical reaction within the cables."

A rewire is dusty, disruptive work — but it doesn't have to feel that way. We've invested in proper kit and built processes that keep your home clean, safe and stress-free throughout.
We use professional Metabo wall-chasing tools with built-in dust extraction — sucking up plaster dust as it's created rather than letting it spread through your home. The difference is night and day compared to traditional chasing.
Cable routing through lofts, under floors and behind walls is done methodically and tidied as we go. Every cable is clipped, supported and labelled so future electricians can pick up the job easily — and so your insulation stays where it should.
Outbuildings, garden offices, EV chargers and external sockets all installed to current weatherproofing standards. We work in all weathers to get your job done on schedule — even if it means evening installs in winter.
The big upgrade most homeowners notice. We safely disconnect the old unit, install a modern 18th Edition consumer unit with full RCD/RCBO protection, surge protection, and clearly-labelled circuits — and dispose of the old kit responsibly.
We're not a faceless national firm — we're Jamie, Dan and the team, a small family-run business who do every rewire ourselves. Here's a glimpse of recent jobs across Hertfordshire and Essex.
A full house rewire including consumer unit upgrade, new sockets and switches throughout, plus mains-powered linked smoke and heat alarms to current Building Regulations. Job completed on schedule with full certification and zero callbacks.
Customer wanted more usable sockets in every room, properly positioned for modern living. We rewired the entire property, repositioning sockets and switches to the customer's brief during the pre-site visit. Clean finish, ready for redecoration.
Modern FuseBox consumer unit installed with full RCBO protection, surge protection device, and clearly labelled circuits. Ten-year inspection sticker fitted. Customer now has peace of mind that the electrics are fully up to current 18th Edition standards.
A larger property rewire requiring a high-capacity consumer unit with multiple individually-protected circuits. Every cable terminated neatly, every circuit labelled, every connection torque-tested. The kind of workmanship behind the scenes that you'd never see — but that makes all the difference.
Clear. Organised. Stress-free. From your first enquiry to the final handover, here's exactly how we make your rewire smooth and straightforward.
We visit your home, listen to your needs and carry out a thorough survey. You'll receive a clear, detailed quote with no hidden extras.
Once you're happy to go ahead, we agree a start date that works for you and add everything to the schedule.
Before work begins, we carry out a detailed pre-site visit to finalise socket and switch locations, discuss timelines, power arrangements, access requirements, and answer any final questions. This ensures everyone feels prepared and confident before installation starts.
We guide you on how to prepare your home with our simple checklist, so everything is ready for a smooth start.
