Can I return to the UK? ... I am a British Citizen
Yes.
Having right of abode means youβre allowed to live or work in the UK without any immigration restrictions, which means:
you wonβt need a visa to come to the UK
thereβs no limit on the length of time you can spend in the country
All British citizens automatically have right of abode in the UK.
(my emphasis)
So, you don't need a ticket for a later flight out of the UK.
I've entered the UK many times without such a ticket.
You write that you are a British Citizen. This is different from a British Subject, a British Overseas Citizen and several other types of British national.
