Sun Room - planning permission needed?

You'll have the same issue with a sun room - By the time you have prepared a suitable base (insulated), added a few lights & sockets, you'll have easily spent £2K or more. You would not be able to plumb the sun room in to the house central heating, so you'd be stuck with electric (expensive to run).

Why wouldn't they be able to extend the central heating into the sunroom?

Regs state that an external grade door is required and it's not heated from the main system, or it becomes an extension.
However a lot of people do stick a radiator in as it does work out cheaper.

Thanks for the information stuart45.  Interesting as our neighbours did extend the central heating into their conservatory, and we were asked by the company who built ours if we wanted to extend ours too.  Seems many don't stick to the rules and very few home owners would be aware.  We had underfloor heating instead.
