Registered providers in this group
- Aster 3
- Aster Communities
- Central and Cecil Housing Trust
- East Boro Housing Trust

The regulator's group look-up tool places these registered providers in this group; the group reports Tenant Satisfaction Measures for all of them.
Tenant Satisfaction Measures (TSM) are reported by each landlord for its whole stock (or its group), not for one area; survey methods differ and the regulator warns against direct comparison. Figures are for 2024/25, the latest published when this site was built.
