Just for the switch?
You can get the switch and a remote for 25 quid from a competitor!
Would be cheaper to get that and bin the remote.
Be aware that B&Q (I don't believe they're OCUK competitors) sell remote light switches for all of £25. I've been using them for a few years now. Wonderful replacement, very cheap and learns from any remote you use. Also dimmable.
Wicked, literally just a straightforward swap job then?
