Thats sh1t rate, best bit of advice mate is move south, London area £20-£30 a metre run, better to operate an hour away and the living and runing cost are easier,
My advice is call local companys give em a chimney stack, basic 2 up 2 down for re-roof and 4m tower 4 lifts, then ask for price over phone.
then work out your metre run from there's.
