But would you let Drivel do your gas pipework? Check you insurance policy
before answering.

I would charge you £500 for a new run. You deserve to pay lots and lots.

Doctor Drivel -it is not me (OP) who is questioning your wisdom. I hope to
be able to negotiate the price down after doing some measurements - it
wasn't a very well considered estimate.
