I got mine done at Rentec in Portabello, Edinburgh, dropped the car off at 11am, ready by 4.30pm,bought the kit myself, but they were very close on price,to do timming belt, aux belt and pump it was just over £200 total..I'm sure i've got a post in this Scotland section about it.
Im taking mine to Rentec in Edinburgh on Saturday. They are doing alot of work for a very reasonable price but the timing belt, aux belt and water pump (with coolant change) is £451.88. Its worth the trip to know its in good hands.
Although iv heard very good things about 'kenneth brown engineering' in Glasgow, he deals with all sorts of performance cars GTR's, Porsches, BMW's, you name it. Iv not used him yet - will do in future - but i wanted a renault specialist to do all the belt etc since im paranoid.
But this would have been at last year prices ,If you are dropping the car off and going into Edinburgh for the day,i got a bus at the end of the road which took me into Princess street. in about 15mins.
