Sounds Reasonable to me. If cost is not a major issue might be worth running 5 core SWA but only connect to one phase for now, then if you need the other phases in future you won't need to run a new or extra cable.

Is this all being done inside the meter cabinet?

If so why dont you just use 25mm tails as long as the run is under 2m.

If not and your running the cable elsewhere.

Is the property PME?

If not buy yourself some Split Concentric 25mm Copper or Aluminium, buy yourself 2 henley cable heads for terminating it into and do it the proper way. Other wise if you require to rewire the supply to the new meter you will need to pull the supply at the 3phase cable head which unless your authorised by the electricity supplier you shouldnt be doing.

Also check that the loading is adequate for the new supply is for a new flat at even though it aint a huge demand it may overload the HV ring (especially so if this is a heavily populated area)
