I'm also based in the North East, I'm sure PDT would be able to help, just carry on down the A19 down through the tunnel and in 5 minutes you're there.
I'm not trying to big up PDT.
But I do like to think I take my car to places I trust and who know what they're doing.
As a result my car has been to Dave a number of times for mods, never had any issues.
The reason the car goes back is that I'm getting it more modded and that's where I choose to use, the fact it is 15 minutes away is just handy..
For ref: My Ed30 Stg 1 Revo remap that Dave did in Dec, installed the same time as an Autotech HFFP, made 311 bhp.
