loft conversion/building regs/insulation?

hotcookie101

Hi, I bought my house nearly 3 years ago, it had a loft conversion done (badly!) about 2-3 years before that, has full building regs approval. BUT it has no CH up there and is FREEZING, with drafts down the rubbish stair case to make the rest of the house colder.
Flooring is laminate, but I presume as it has building regs approval they must have insulated the roof panels? The roof was replaced with concrete tiles at the same time, and I think they had to strengthen some joints etc. We don't really use it (waiting to win the lotto so can make it a sensible space as opposed to what it is!) but just wondering if I can do anything to reduce the heat drain to the rest of the house. Thinking of a big long curtain at the bottom of the "spacesaver" stairs any other ideas?

if it has building reg approval then there should be a door to enter the room or the stairway.
it should probably even be a self closing one.

If there is no door then why not fit a door? They can be bought fairly cheaply - £20 will get you a decent door.

There is a proper fire door at the top of the stairs to the conversion, but even with this closed (it is self closing so never left open) there seems to be a powerful draught down the stairs

Fit a door at the bottom of the stairs?

Sounds like there is a BIG hole letting the draft in or do you leave in a really windy area? I would try and track down where the draft is coming from before you start fitting more doors. If you really can't be bothered to do that why not "seal" the fire door, you can get the stick on seal and brush type seal quite cheaply.
