[UK] Looking for recommendations for a 16-20 Port 2.5Gb switch

I'm looking for recommendations for a 16-20 Port 2.5Gb switch. Probably unmanaged, but open to suggestions as to why I should choose a managed one; PoE is also not required.

Ideally I’d like it to be as compact as possible and not really a rack sized one for a server.

It will be going in a store room downstairs next to the electrical consumer unit and act as a main hub for the majority of the Ethernet in the house which is currently being completely rewired during some major renovation works for my parents - so the less they have to spend on this switch the more palatable the purchase is which is slightly over-specced but future proofed.
