Perished Rubber Cabling – Homes in Blackburn built before the 1960s often have VIR (Vulcanised Indian Rubber) cabling which becomes brittle and poses a significant fire risk.
Lack of Effective Earthing – Many older properties lack modern earthing on lighting circuits, increasing the danger of electric shocks from metal switches and fittings.
Green Goo (PVC Degradation) – If you see green liquid inside sockets, your 1970s-style PVC wiring is reacting with the copper, which can lead to overheating and failed circuits.
Insufficient Socket Outlets – Older wiring plans weren't designed for modern life. Overloading extension leads because of a lack of sockets is a primary cause of electrical fires.
Frequent Circuit Tripping – If your breakers trip often or fuses blow regularly, your existing wiring is likely struggling to handle the load of modern high-power appliances.
01
We conduct a thorough inspection of your Blackburn property to map out current circuits and plan the most efficient route for new cabling with minimal disruption.
02
This is the structural stage. We install all new cabling, back boxes, and conduits throughout the property while ensuring the structural integrity of your home is maintained.
03
Once the walls are ready, we install the visible components: your new sockets, switches, and a modern fire-rated consumer unit with full surge protection as standard.
04
Every circuit is rigorously tested to ensure it meets 18th Edition safety standards. We leave you with a safe, fully functional, and future-proofed electrical system.







If your Blackburn property is over 30 years old and hasn't been updated, or if you notice rubber-coated cables, frequent flickering lights, or sockets that feel warm to the touch, it is likely time for an inspection. We provide a free visual assessment to determine the state of your wiring.
Not necessarily. While a full rewire is an invasive process, we can often work in stages (phased) to keep you in your home. However, it is much faster and cleaner if the property is empty. We will discuss the best approach for your specific situation during the survey.
A typical 3-bedroom semi in Blackburn usually takes between 5 to 10 working days. This depends on the property size, whether it’s occupied, and the complexity of the "First Fix" infrastructure stage.
Rewiring involves cutting "chases" into plaster to run new cables, so there will be dust. We mitigate this by using specialised dust extraction tools and floor protection. We ensure the work area is left as clean as possible at the end of every day.
Yes. If your cables are in good condition but you need extra sockets or a specific circuit (like a kitchen or extension) updated, a partial rewire is a cost-effective solution. We will only recommend a full rewire if the existing system is unsafe.
Yes. Every full rewire we perform in Blackburn includes the installation of a modern, 18th Edition fire-rated metal consumer unit with full surge protection as part of the package.
