House rewiring or just a new fuse board?

It would be more sensible to get a full Electrical Installation Condition Report carried out, this would give an objective opinion based on the actual results from physical tests and inspections. It is likely that a rewire is not actually required, but some updating will be needed as the wiring regulations have been updated several times since 1986.

A rewire gives the comfort that years of reliability would be expected. As for suitability of using existing wiring inspection and testing would prove either way

I think having a electrical installation condition report would be best option. The report would pick up any deterioration or faults in existing wiring. Most times brining distribution board up to regulations is adequate.

I agree with the above comments. A decent electrician should be able to do a visual first and foremost and tell if wiring looks old, and then if so he would offer a test. Expect to pay a small fee for the test as it will take the electrician time to undertake, however if deemed safe for continued use it will save you a lot of money and upheaval. In my personal experience, 1986 would indicate that the lights should have an earth already in the circuit so perhaps the new board would be sufficient. However, if you are looking for long term confidence, then perhaps Rewire will be the best option.

Considering your situation, it's commendable that you're looking to upgrade your electrical system to meet modern standards. Given that your house was built in 1986 and likely hasn't undergone significant electrical updates, a whole house rewire might be a sensible option as a home that age normally has an insufficient amount or sockets for modern living. The old-style fuse board/consumer unit is a clear indication that your electrical system is outdated, and upgrading to a modern consumer unit with RCD protection is a crucial step towards enhancing safety. It not only brings your home in line with current regulations like BS 7671 but also significantly reduces the risk of electrical faults. It would also be advisable to add surge protection while doing any upgrades due to the amount of expensive electrical items in a modern home. As for the connection issue with the light, it's possible that resolving this may involve localized repairs rather than a full rewire. However, it's essential to assess the overall condition of the wiring. Wiring deteriorates over time, and a comprehensive inspection can reveal if there are hidden issues that might pose a safety risk in the future. In summary, while addressing the specific issues like the fuse board and the light connection might be possible through targeted repairs, a whole house rewire provides a comprehensive solution. It ensures the entire electrical system is modern, safe, and compliant with current standards. Given the age of your house and the potential lack of updates over the years, a complete rewiring might be a wise investment for the long-term safety and functionality of your home. Before making any decisions, it's advisable to consult with an electrician who could carry out an EICR to check the current condition of the installation and provide you with a report and advice based on the specific conditions of your home.
