Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what information his Department holds on the number of service family accommodation and single living accommodation for military personnel that do not meet the Decent Homes Standard.

As of 23 October 2026, of the 47,173 Service Family Accommodation (SFA) properties maintained by the Ministry of Defence (MOD), circa 2% were assessed as falling below the Decent Homes Standard (DHS), while circa 98% met or exceeded the DHS Standard.

Under the plans set out in the Defence Housing Strategy, nine in 10 Defence homes will be modernised or upgraded, including over 10,000 homes that will be substantially refurbished or replaced through major renovation or new build programmes. This will be supported by £9.2 billion of investment over the next decade and delivered through the Defence Housing Service.

SFA that is graded DH- is not allocated to families when they apply for SFA, but homes may be downgraded to this standard during occupancy.

Single Living Accommodation (SLA) is not assessed against the DHS. Defence has introduced its own Defence Minimum Standard (DMS) that applies the intent of the Decent Homes Standard but considers the unique nature of SLA.

The SLA estate was last assessed against the DMS in 2023, and 72% of SLA met or exceeded DMS.

The Government is committed to improving the living conditions of Service Personnel. The Defence Investment Plan includes £1.4 billion over this Parliament for SLA, supporting the modernisation of accommodation and improvements to living standards across the Defence estate.

A review into Single Unaccompanied Living Accommodation has been undertaken and is pending finalisation.
