About us


We are committed to ensuring that our business is well-run and that we are true to our social purpose and the vision and values which drive our success.

Our Overlap Boards are responsible for making sure we meet these commitments supported by our Executive Board. The overall role and purpose of the Executive Board is to ensure that there is effective leadership of, and a system of assurance between, the operations of the Aster Group and the Overlap Boards and their sub-committees.



Our group structure

Aster Group brings together our specialist housing businesses under one brand, ‘Aster’. The parent company of our Group is Aster Group Limited. 

In 2014 we introduced an ‘overlapping’ or ‘integrated’ board structure. This means that the same people sit on the boards of a number of group companies and that these boards meet at the same time. The legal identities of these companies and the directors’ duties to each company remain separate. 

This cross-membership framework allows our parent company and five key subsidiary boards to meet regularly as  “Overlap Boards” ensuring that we think and act as one organisation with a shared purpose and vision. Our special purpose companies have their own board of directors. 

On 31 March 2020 East Boro Housing Trust joined Aster Group. As part of the Group, East Boro retains its own Board and governance structure.

Modern Slavery Statement 2020/21

We are committed to ensuring modern slavery does not occur in our business or supply chain. We will adopt procedures and policies which address the risks of violations of anti-human trafficking and anti-modern slavery laws, and we expect other organisations that we work with to adopt and enforce policies to comply with the legislation.

Our Modern Slavery and Human Trafficking Policy reflects our commitment to acting ethically and with integrity across our own activities and to provide assurance we have effective systems and controls to ensure modern slavery is not taking place anywhere in our supply chains.

Complying with regulations

Aster Group is a not-for-dividend developer and landlord.

We are subject to a diverse range of laws, rules and regulations relevant to our business which we must take all reasonable steps to comply with. Regulatory compliance describes the policies, systems and processes we use to achieve compliance. Operating with a framework to support our ongoing compliance and providing assurance to our decision-makers, ensures they can make informed decisions based on accurate and credible information.

Examples of Aster’s regulators are:

  • The Regulator of Social Housing (RSH)
  • Information Commissioners Office (ICO)
  • Health & Safety Executive (HSE)
  • Financial Conduct Authority (FCA).

The Regulator of Social Housing (RSH), sets ‘Economic’ and ‘Consumer’ standards all housing associations are expected to meet.  Aster holds a rating of G1 (governance) and V1 (financial viability), meaning Aster is well run and financially sound.

Economic standards relate to governance, financial viability, rent-setting and value for money. Consumer or ‘customer’ standards determine the services our customers can expect to receive. These include expectations about involvement, the physical quality of their home, their tenancy arrangements and the landlord’s role in their neighbourhood.
