Each job can be different therefore you have to you have to weigh it up on its own. Iv'e just looked at job where a few sparks have been round and recommended a rewire (quite a big property) and one said the people need to move out lol
There's no evidence of any paper work to suggest a rewire and the people paid £150 for some testing and one of the circuits was disconnected from the dis-board.
Basically had the p*ss took out of them and its not right.
I agree. Sometimes its more desirable and in a selfish way its often easier to go with the belt and braces approach and like you mention in your example re-wire the place (not least because your a**e is covered.
Before the recession this was often the case and most clients would agree. I am now finding in recent years that clients are wanting the minimum requirements and I feel that its my job, to recommend the most suitable solution based on regulations, health and safety, cost but also to cover myself.
