Wiring for heater

[empty_vessel]

Is this ok? I'm having the kitchen done and just need to make sure that a new FCU for a heater isn't going to involve a load of extra wiring.

Socket on ring --> Switched FCU to Boiler (3A fuse) --> Switched FCU for hydronic plinth heater (5A fuse)

I think the Switched FCU to the boiler is on a spur (it's only a few inches from the socket) and not part of the ring but I can check if necessary. My gut feeling is that if the boiler FCU is a spur its not allowed.

Thanks for any help,

Just got home and checked - Boiler FCU is a spur off the utility room ring circuit. Am I right that if I take the switched FCU for the heater from the load side of the Boiler FCU that the installation would be ok?

On a slight aside - does a utility room class as a special location? There is no sink, so if I interpret the info from the wiki article on Part P I could do this myself? Don't really want to pi$$ the sparky off by asking him to do this as well, he's already been back for loner than he originally planned.

Thanks, e_v
