The new light (Homebase Colours Bathroom) looks like it needs L & N only (blue and brown wires). But the old light had two browns. I am not going to remove the rose, hoped to stick the new base over it, but the existing wiring puzzles me.
Please help with light fitting

No problem - but ensure you do the work in daylight with all power switched off at your consumer unit. Since your knowledge is limited this is the only safe way for you to work
Your new live wire (brown) connects to the black lead (on the right of the photo)with the red sleeve on it. Your new neutral wire (blue) connects to the black wire on the left of the photo. If your new fitting has a metal body it should also have a green/yellow wire and this connects to the single connector that the other green/yellow wires are connected to.

Nothing seems wrong with what you show. The ceiling rose not only holds the lamp but also acts as a junction box. You must:-
* - Be careful not the lose the red sleeve on the switch return wire. This black wire is NOT neutral but is a line feed to the light.
* - Ensure all earth wires are connected together or lights else where in the house will not be protected.
* - Ensure the line wires are not where some one working under the floor boards could touch them.
If the ceiling rose is too big to allow new lamp to fit over the top either modify new lamp swapping connector block for one with more connections. or use a maintenance free junction box and do all connection in that then use a small lenght of wire from that to new light and hide junction box in ceiling void.

Thanks, did a test connection, - works like a charm !
The body is indeed metal (with a layer of paint all over it), where can I get a spare green/yellow wire, it is not in the box and I don't remember seeing them in B&Q ?

If your light fitting is metal and B&Q are selling it without an earth facility then I think you need to be asking them some questions. Is there an earth connection terminal on the casing ?
It could be class 2 even if metal, or
12V with integral class 2 transformer.
Does it have the class 2 symbol somewhere?

Yes, it does have the Class 2 symbol as above on the base of the unit.
I take it there is no need to worry about earthing then ?

No, and more than that - you must not earth it.
Seems a little strange that a device supposed to be class 2 has a metal enclosure inside which you have access to the wiring connections. I thought (obviously incorrectly ) that the double square suggested double insulation with no possibility of the user making contact with an electrical source. If you do a botched wiring then the metal enclosure could become live. 
That is a good point and perhaps it would be better to wire it from a junction box above the ceiling.Seems a little strange that a device supposed to be class 2 has a metal enclosure inside which you have access to the wiring connections.

Although even wired 'correctly' the live conductor could become loose.
Could we have a picture of the new fitting or a link to it?
Would there be room within the new fitting to put on the rose cover?
