A meeting took place this afternoon between the CAA Flight Operations Department and CAA Airspace Policy, they have confirmed that any Letter of Agreements in place before the SI remain in force.
In the case of Redhill we are back to operating clear of cloud, surface in sight with minimum meteorological visibility of 5000m for fixed-wing aircraft and 1500m for helicopters.
I have to say that Flight Ops have been much more proactive in this than AATSSD.
