New flat conversion – electric or gas?

I am converting a semi-detached large house into 5 self contained flats. 4 x flats will be 1 bedroom and 1 x 2/3 bedrooms.

The 1 x 2/3 bedroom flat will have gas and I was contemplating gas central heating for the others too. However, I am now reconsidering as now the partitions are going in, they do not actually look that big (around 35 sq.m). They would only need 1 radiator in the living room/kitchen, 1 in the bedroom and 1 towel rail in the shower room.

Given the above, I was thinking of keeping the 4 x 1 bedroom flats as electric only with electric radiators and a electric handwash for the kitchen and bathroom sinks. Obviously, this will save me capital outlay, but the other reason in support of my thoughts around electric is because everything (and I mean everything as it is back to brick) will be brought up to modern standards in terms of insulation.

The potential capital outlay saving is circa £8000 (if i budget £2k per flat for boiler, piping and radiators). However, if I were to have gas, now is the time to install it as everything is ripped up.

Thoughts and opinions?
