No. They are working on a Qatari aircraft, not on UK soil. It is up to the aviation authorities to approve or deny the wet lease.
We didn't have Kenyan work visas when we used to spend 7 days in Nairobi doing daily shuttles to third countries, nor do the Philippine airlines crew who spend lengthy periods in Vancouver doing daily flights to the US have Canadian work permits.
Aviation and shipping are different to other industries regarding immigration laws. You need to be able to work in the state of registry not the destination.
