If UKVI had done any verifications then ................trouble for sure......maybe impacting future Visa Applications. It has happened so many times before.
Immigration Rules part 9, grounds for refusal, Rule 320, 7B:-
(7A) where false representations have been made or false documents or information have been submitted (whether or not material to the application, and whether or not to the applicant’s knowledge), or material facts have not been disclosed, in relation to the application or in order to obtain documents from the Secretary of State or a third party required in support of the application.
