Is there any legislation covering the installation of wall mounted heaters?

We have just had a conservatory built, and part of the package was for the builders to install two slim line panel heaters on the walls. While they have had an electrician do the wiring for the lighting and the sockets in the conservatory, and they have fitted the heaters to the wall, they have not either wired the heaters into a fused spur, or even fitted plugs to them. I think there is some sort of legislation that says that panel heaters are classed as fixed electric units, and as such have to be 'spurred' in. If not, they have to at least be fitted with a plug, and are then classed as a portable appliance. Afterall, if you got someone out to fit an electric oven, you wouldn't expect them to leave you with 10mm cable for you to stick a plug on, would you?? lol Can anyone advise please?Is there any legislation covering the installation of wall mounted heaters?
They are not porable appliances they are fixed to the wall, there is no regulation that they have to be connected to a spur unit, they must have been left for you to plug into one of your new 13amp sockets, these heaters do not come fitted with a 13amp plug top, but out of good p.r. they should have fitted plug tops on them with the correct size of fuse and made sure that they were working properly.Is there any legislation covering the installation of wall mounted heaters?
Your local county inspector will have to answer that one. he will sign off on the electrical part of your building. Hope you had a permit.Is there any legislation covering the installation of wall mounted heaters?
Building control should be able to answer this for you.
They do have to be spurred in and the plug that they are wired to has no on of switch, but has a red warning light to let you know when they are on.
