After posting I found a report on spot lights in ceilings.

I hope the sysop will allow the link as this is rather important.
As well as fire risk it also refers to:-
There is another important aspect that can have an effect on downlight choice and fitting. Until recently, recessed downlights were installed in homes and workplaces with little or no thought to heat losses, or the effect they might have to ceiling voids or loft spaces. However, the global focus on climate change, energy efficiency, CO2 emissions and high energy prices has resulted in a requirement that modern recessed downlights have to comply, not only with Part B, but also Part C for air flow, heat and moisture losses, and Part E for acoustics (the transmission of sound). Cutting holes in ceilings also creates compliance issues with these, and there may also be issues with National House Building Council (NHBC -
www.nhbc.co.uk) requirements.
Personally this complying with Part B, C and E is just too much hassle I would just not use spot lights.
