You would buy from an installer - the manufacture of these things is quite easy and so the manufacturing industry is very fragmented. My parents' cost (iirc) £6k and they got a £2k grant under the Clear Skies programme, which has been replaced with the Low Carbon Buildings Programme, here: http://www.lowcarbonbuildings.org.uk/home/ for which the applications process is apparently a nightmare, with relatively low caps for total applications processed each month. The site gives the standard cost of a system as £3,200-4,500, with a 10-year warranty and the suggestion of a yearly check by householder and a professional check-up every 3-5 years.
The best way to find an installer is probably by looking at their 'certified installers' list, or at the Solar Trade Association, http://www.solar-trade.org.uk/
It's hard to tell if these are expensive. Depends on far too many factors (for example how many people are taking baths or showers, how good you are about taking cool showers when it's only a bit sunny, whether you quit with the dishwasher etc). My parents think it's probably paid for itself, but are not really sure.
