OK, thanks. £125 seems like a lot, did that include the screen as well at that price? I expect you've already made purchase but if not try this:

you will need two for a twin circuit screen which will total approx. 38Amps.
So you'll need a relay (10 minute timer @ £11.72) for the screen,
cable (39Amp, approx. 6m @ £0.90 per meter),
a fuse/ holder (@£2.00) at the battery,
a momentary switch (£2-10),
connectors (£1) and your done.
I reckon about £40 all in or £50 for a two relay system.
If you are adding more electrics do it properly and have a good connection at the battery, this seems like a good idea:

Maybe overkill but would certainly future proof your bus and stop running all your electrics through the ignition switch.
