The Combined Accommodation Assessment System (CAAS)

The CAAS for SFA is the method of setting charges in the UK and overseas. It replaces the 4 Tier Grading (4TG) System (except for Germany). CAAS is a fairer and less subjective system than the 4TG System, and ensures that charges for SFA are set in accordance with modern, nationally recognised standards, utilising the Ministry of Housing, Communities and Local Government Decent Homes Standard. Where charges increase there will be transitional protection that will set a maximum cap for the increase in any single year. 

CAAS charges

The CAAS ensures charging in Scotland, Northern Ireland and Wales is in line with England by including a location assessment based on access to local services. This delivers a fairer application of the UK Location Factor to all SFA across the UK.

If you have a standard query about your pay in connection with SFA charges, please contact the Pinnacle Service Centre on 0800 031 8628, providing full details, such as your service number, about why you believe that charges have been applied incorrectly so this can be investigated.

CAAS challenges

CAAS challenges are handled in two stages and are separate from the SFA complaints process.

If you wish to challenge or appeal against your charge as a result of the CAAS, the correct procedure is set out on the CAAS challenges page on the Defence Intranet.
