Thanks guys for the advice.
Have made a few calls over the last couple of days to dealers and a local mini tuner,
Dealer quoted me £100 inc vat to fit new belt, which i didn't think was to bad.
Local tuner said that he didn't get asked much to fit just a standard belt, said i should fit a 15% alta pulley and belt. Priced them up came out at £120 ish + fitting,had been told it was only a 40 min job. I thought it would be about £200 fitted, then they said no point having pulley fitted without having remap as the car would run to rich. They could do the whole job for £700+ vat

OUCH! Too rich for me at the moment, so asked for a price to do the standard belt £120+vat.
Think im going to get Vines the dealer to do the job, plus while cleaning my car yesterday i found a couple of bubbles in the paint work, so going to get them to sort that too.
Thanks again Keith
