FCU wiring question

Hi all,In my airing cupboard I need to install two new electrical devices :1. a wiring centre for a central heating control system. The wiring centre has it's own 2A fuse.2. power to a relay box for a wireless room stat. This has no fuse and clearly it is intended to be connected through an FCU.Originally I was going to wire these off the spur for the immersion heater. However, there is a double socket on the wall immediately outside the airing cupboard, so instead I can take a spur from that through the wall. This has a small advantage in that I can still in the future isolate the immersion heater if required without also isolating the heating system.However, I'm aware that the regs permit the wiring of only one FCU off a spur - but I need to wire two "appliances". What's the best option ?I know that the regs allow a double socket to be taken off as a spur so I could just stick plugs with fuses on the end of my two devices and connect them that way, but there's something about that which doesn't "feel" right.Is it permitted to connect two low-current devices like this into a single FCU ? Alternatively, is there another way ?
