I am building a replacement bay and have already preapared the base. The brickwork is going onto a very sturdy concrete base. The local sub-strata is heavy clay (north-Lincolnshire).

All cement is Ordinary Portland cement unless it is special i.e Acid resisting of Sulphate resisting etc. Therfore just use it with your mix either 4/1 or 5/1 for brickwork with feb plasticiser . protect new brickwork from rain for a few hours after finishing.

Well, I'm not familiar with building in England, but I have two observations for your consideration. First, portland cement is an ingredient in concrete. Used by itself, cement isn't very strong, that's why they make concrete. So your foundation should be concrete with at least 3,000 PSI (American units) strength, stronger would be better. You will also need to reinforce the concrete with rebar. This should be designed by a structural engineer.
The second thing is clays generally are a poor base to build upon. The problem with clay is it's high plasticity. It's hard when it's dry, but looses it's strength when it gets wet. It also swells and shrinks with the wet and dry cycles, and this can cause movement in your foundation and unexpected stresses.

As part of a concrete mix, yes. Cement by itself is too brittle.
for mortar, yes cement is ok with a softsand mix.
You could try a hydraulic lime mix instead ? More ecologically friendly than cement

Yes its fine and as a matter of interest the Dutch do not bother with DPC's since the advent of Portland cement
