Is this bathroom re-fit over priced?

I have received a quote from a reputable local bathroom installer. they will completerly gut my bathroom and fit new p shaped bath with shower linked to combi boiler, new toilet, basin built into furniture cupboards with slimline cupboards and illuminated mirror above. intsall 6 low voltage spot lamps in ceiling , tile two full walls and plaster two other walls. tile floor.supply and fit the lot £5,500. they say it will take a week. is this about right, a rip off or a deal?
Answer
It all depends on the quality of the fittings,these can vary alot.with a job that size i would definitly get a second quatation and ask for both to be split down in to parts and labour.
