There is no fixed expiry date for house wiring. Plenty of installations from the 1980s are perfectly serviceable, and some from the 1990s are not, because what matters is the cable type, the condition, how the installation has been altered over the years and how the household now uses it. An inspection and test gives you an evidence based answer instead of a hunch.
Signs worth taking seriously
Any one of these is a reason to have the installation looked at properly.
- Rubber, lead or fabric insulated cable, which is well past its service life
- A rewireable fuse board with no earth leakage protection
- Round pin sockets, or sockets and switches mounted in skirting boards
- Repeated unexplained tripping, or circuits that cannot be reset
- Scorch marks, a burning smell, or warm accessories
- Very few sockets per room, leading to permanent extension leads
Full rewire or partial
A partial rewire is common and often the right call. If the ground floor was redone during a kitchen refit and only the upstairs lighting is original, there is no reason to rip out sound work. A good electrician will tell you which parts can stay.
Timing it with other work
Rewiring is disruptive because cables need routes through walls, floors and ceilings. If a renovation, extension or new kitchen is planned, doing it in the same programme saves a second round of chasing, plastering and decorating.
What an inspection gives you
A condition report sets out coded observations, so you can see the difference between something that needs immediate attention and something merely recommended. That report is what turns a rewire from a sales pitch into a decision you can check.
Common questions
- How old is too old?
- There is no set age. Cable type and test results decide it, which is why we inspect before recommending.
- Can we live in the house during a rewire?
- Often yes for a partial rewire. Full rewires are easier with the property empty, though many households stay put room by room.
- Does a rewire include a new consumer unit?
- Normally, yes. A new installation is protected by a modern board and certified as a whole.
- Will you make good afterwards?
- We agree making good in the quote so you know exactly what is included before work starts.
Book an inspection and we will tell you honestly whether a rewire is needed, or whether it is not.
