best way to supply garage mains

[cleverspark]

Hi Just a quickie, I am planning to run mains into my garage, from a 50A MCB using 10mm cable to a junction box and then SWA cable underground to a new consumer unit in the garage. Problem been is that I want to use the junction box under the floor and then tile over the floor. I understand that it is a requrement when testing that all junction boxes have to be accesible for inspection, therefore has anyone got a better idea how to terminate to the SWA cable that wont look untidy.
Cheers

Terminate the SWA in a steel adaptable box adjacent to the CU. No JB required as the cores and the earth wire from the banjo can pass from one enclosure directly into the other.
