How do I replace this with a timer

[CumbrianRed]

I'm wanting to replace this towel rail switch with a timer so I can have it go on for half an hour a day. As it's a bathroom I realise it will need to be done differently. Can you help?

Inside the bathroom:

Outside wall:

Cheap and simple are the priorities. Thanks very much for your help.

Swap the fused spur outside the bathroom for one of these: https://www.timeguard.com/products/...imeswitches/fst77-7-day-fused-spur-timeswitch

Watch out on the earthing if the backbox is metal, its likely currently earthed through the eyelets on the accessory, those timer spurs just have a brass earth holding terminal which goes no where as there are no eyelets, so a flylead is required

Thanks. Is there anything a bit simpler I could use? I'm not sure if this would work:

Greenbrook 24 Hour Mechanical Socket Box Timer

Chances are that current supply is off the sockets circuit, so you need the fused spur to fuse down, you also want some means of isolation for the heater. So you could use that, but you'd want to be putting it after the existing fused spur not instead of it.

Those timeguard units are simple to set up and will take care of the switch between GMT and BST themselves too

Fwiw timeguard products tend to be more reliable and there is a WiFi version of their product too
