I've heard it said many times that connector blocks are not allowed to extend cables inside DBs and whilst I agree it's not good practice, I've never found a regulation that specifically prohibits the use of connectors blocks. Does anyone know of a regulation number regarding this?

There isn't a regulation that says you can not use them. Like most "good practice" guides over the years it as morphed into a "regulation against" 134.1.4 is the guide.

A DB is full of screw-terminal connections already - can't see the problem with another one! Daz

Connector blocks are allowed but ideally should be fixed in place not floating.

I just twist together tape and move on.

Joke by the way I've used wago before inside when all other avenues exhausted and can't practically or financially be avoided

splice, solder and heatshrink if you are on a budget.

12p for a push-in splice connector 30 secs to fit. solder and heatshrink + time about £8. which is best for a budget?

£8 will give 100g of solder and 11meters of heatshrink. that should last for a while. takes 2 minutes to do the joint if you have already hot iron.

time to plug iron in. search the van for solder, wait for it to warm up, solder the joint, then unsolder as you forgot to put the H/S on first, then get the heat gun from under the front seat where you forgot it was. sod it. i'm packed up and in the pub while youre waiting for your iron to cool down.
