I was wondering if it was possible to reapply and get granted a new UK visa immediately after the previous one expired?
The answer is expressly yes it is possible. It does not mean it will be approved. There is nothing like a cool off period one has to wait for between UK visas or UK visits. Remember we have even 10 year visas.
You indicated the work youβre doing (installation of products) is covered by the rules for visitor visas and was explained in the previous visa application so that is not the question I am answering, ie the legality of what youβre doing on a visitor visa.
Your legal stay is controlled by the length of your visa and the duration the immigration officer gives you at entry. The standard is either six months or the duration of validity remaining on your visa, whichever is shorter. You can turn around immediately after the first six months, exit the UK and renter the next day.
We have a canonical answer about personal impact and articulation skills which will be instructive in this scenario. In situations like this your ability to convince the immigration officer at the airport after convincing the ECO to issue the visa is absolutely crucial.
REFERENCE
I applied and received a 5 year visa less than a week after my previous 5 year visa expired.
