Any new circuit (post 2006) has to be completed in new colours I'm afraid Archie. It is very unlikely to be approved if done in red & black. Realistically anyone can come along and sheath the ends of cables to give the "appearance" of a new installation so full cable needs to be installed in the new colours with the connection made in an accessible junction box.

Yes OK to sleeve. There was a big discussion over the over sleeving of an earth wire when using three core flex for items like cistern thermostats some thing which I would have considered a big no. But the Electrical safety council has it on there web site that even this is OK. With singles no not permitted but with twin and earth yes no problem with line and neutral to over sleeve. You could not over sleeve the bare cable to be anything but earth because it's not insulated the line and neutral is no problem.

However twin and earth cable in for inside use only so unless the garage is attached to the house in some way then twin and earth is not suitable it really does not matter what colour it is.

Cables used outside are normally black to resist UV from the sun. Normal would be SWA cable but there are other options.

hi.. i applied for a part p test and was given the contact details of the person who would be testing, i rang him and he was happy for me to use red & black 16mm t&e and said he would put a sticker on the consumer unit stating there was mixed red, black, brown and blue cables inside..

thanks for all the advice..
