Old wiring is not just inconvenient — it is dangerous. In the UK, electrical fires caused by deteriorating wiring are still one of the most common household hazards, and many older homes in Glasgow and Renfrewshire still have wiring that was installed decades ago, well before modern safety standards.
At The Electrical Project, we carry out full and partial rewires across Glasgow and the surrounding areas. In this post, we explain the key warning signs that your home may need rewiring, what the process involves, and how much you can expect to pay.
What Is a Full House Rewire?
A full rewire involves removing all the old cables, sockets, switches, light fittings and the consumer unit, and replacing them with modern, safe wiring that meets the current BS 7671 wiring regulations. It is a major job, but it future-proofs your home, improves safety, and is often essential if you are renovating, extending, or selling.
Top Signs Your Home Needs Rewiring
1. Your Wiring Is Over 25 Years Old
If your home still has the original wiring and it was built before the late 1990s, it is likely due for an upgrade. Rubber or fabric-insulated cables, aluminium wiring, and old fuse boxes with rewirable fuses are all red flags.
2. Frequent Blown Fuses or Tripped Breakers
If your fuses blow regularly or your circuit breakers trip without an obvious cause, your circuits may be overloaded or your wiring may be deteriorating. This is a warning sign that should not be ignored.
3. Discoloured or Scorch Marks Around Sockets
Brown burn marks, melted plastic, or a smell of burning around sockets or switches indicate overheating connections. This is a serious fire risk and needs immediate attention from a qualified electrician.
4. No RCD Protection
Residual Current Devices (RCDs) are designed to cut power instantly if someone gets an electric shock. If your fuse box does not have RCDs on the socket circuits, your installation does not meet current safety standards.
5. Wooden-Backed Fuse Box
Old fuse boxes mounted on wood or asbestos backing are a known fire risk. Modern consumer units are metal-clad, properly ventilated, and fitted with MCBs and RCDs for reliable protection.
6. Aluminium Wiring
Some homes built in the 1960s and 1970s were wired with aluminium instead of copper. Aluminium expands and contracts more than copper, leading to loose connections, overheating, and fire risk over time.
7. You Are Renovating or Extending
If you are undertaking major building work, it is the perfect time to rewire. Running new cables before plastering saves cost and disruption, and ensures your new rooms have safe, modern electrics.
What Does a Rewire Involve?
A typical full rewire is carried out in two stages:
First Fix
This happens before plastering. Floors and walls are lifted where necessary to run new cables to every socket, switch and light point. Cable routes are planned to minimise disruption.
Second Fix
Once plastering is complete, sockets, switches, light fittings, and the new consumer unit are installed. The entire system is then tested and certified.
How Long Does It Take?
A typical 3-bedroom house takes 5 to 10 days. A 1-bedroom flat takes 3 to 5 days, and a 4 to 5-bedroom house takes 10 to 15 days. If the property is occupied, we work room by room to minimise disruption. Many customers stay in the property during the rewire, though it can be dusty. For empty properties, we can work faster.
How Much Does a Full Rewire Cost?
Costs vary depending on property size, accessibility, and the number of circuits required. As a rough guide, a 1-bedroom flat ranges from £2,500 to £4,000, a 2-bedroom house from £3,000 to £5,000, a 3-bedroom house from £3,500 to £6,000, and a 4-bedroom house from £5,000 to £8,000. These are estimates. We always carry out a free site survey and provide a detailed, fixed-price quotation before any work begins.
Do I Need a Partial Rewire Instead?
Not every property needs a complete rewire. If only certain rooms or circuits are problematic — for example, the kitchen, an extension, or an upstairs ring — a partial rewire may be sufficient. We will assess your installation and recommend the most cost-effective solution.
Certification and Compliance
All rewires carried out by The Electrical Project are fully certified to BS 7671 wiring regulations, Part P notified to Building Control, backed by our workmanship guarantee, and suitable for mortgage lenders, insurers, and solicitors. We provide an Electrical Installation Certificate and notify Building Control on your behalf, giving you complete peace of mind.
