Any makers to avoid? Need something that takes little space and is good

Before you do anything else you need to apply for consent to the
Environment
Agency. Assuming they agree, and they may insist on an alternative such as
an underground treatment plant, you will also need Building Control
approval
as well.

We have that already - We have to move or septic tank from a neighbour's
property to our own (letting the easement go), so we have obtained approval
(took weeks) for both the tank and a soakaway. It' snow down to which tank
to use...
