 .uk

The .uk domain names must be more than 2 "letters" long - ab.co.uk would not be allowed but domains with 1 letter and one number - i.e. 1b.co.uk or b1.co.uk would be allowable.

.uk

Top level domains are not allowed as third level domains - i.e. net.org.uk or com.co.uk would not be allowable.

.ltd.uk
.plc.uk

For both .ltd.uk and .plc.uk domain names the domain name must exactly reflect your company name - for instance if you were called "Allied British Carpets Ltd." you would have to register either "allied-british-carpets.ltd.uk" or "alliedbritishcarpets.ltd.uk" - you could not register "abc.ltd.uk".

.gov.uk
.ac.uk

Registrations under either of these domain types are subject to approval and should be related to the registrant organisation.
