Ceiling lights flicker when turned on

[Specialist]

We had our usual electrician in to look at the problem. Of course the lights didn't flicker when he came in, but he did spot check all of the fixtures and said there were no issues. Given that we still have flickering lights i was just keen for advice on whether we should be concerned?

Did he check the connections in the consumer unit ?, That would have been my first check if you'd called me out and told me that all your lights were flickering.

If as you say the lamp holders are gone brown, then they have been overheated. Possibly by someone using high wattage bulbs in the past or just cheap lamp holders. Easy enough to resolve.

As mentioned by others get someone decent in and check form the CSU no floorboards should need to be lifted as the cable runs from the CSU to the ceiling rose and to the next one from the ceiling rose to the switch so it should be standard wiring without anything jointed elsewhere.

Unless you live in some Stately home in between St James Park and Victoria......

It could even be the connection between the circuit MCB and busbar or an internal fault causing intermittent resistance in the MCB itself.
