I've never heard of council MOT centres, unfortunately there isn't one for about 15 miles and Renault is just around the corner.
I've booked in now, £39 inc. for the MOT and £49 inc. for the air con regas which includes dye in the system and leaving it to run a while to check for leaks.
Also need to get a new keycard as I lost my spare, programming is £43 and am waiting on cost of the key. I think this is probably quite cheap compared to prices I've seen on here.
All prices are from Archie moss in Loughborough, very friendly and informative on the phone.
EDIT: Keycard cost £95 +VAT +Programming at £43 ......ouch! £157 for a new key does take the piss a bit
