About AES Sustainability Consultants

AES Sustainability Consultants (formerly AES Southern) is a leading technical consultancy that delivers value engineered solutions across the housebuilding and construction industries.

We provide high quality advice and technical support throughout the lifecycle of a development, from land buying and planning stages right through to post-construction testing and certification. We also ensure you meet stringent environmental regulations cost effectively.

Our aim is always to add value to your project while minimising risk. We never cut corners, and we pride ourselves on always providing information and recommendations our clients can rely on.

As an AES Sustainability Consultants client, you also get complete cost-certainty. We provide transparent fees for projects, have a deep understanding of the national calculation methodology and will always make you aware of any cost savings we identify.

In addition, we work in partnership with our sister company, AES Compliance & Testing enabling us to deliver on-site testing and inspections which ensure the fast turnaround of EPCs and certification.

A great relationship – we work closely with you to ensure we understand your requirements and make a valuable contribution into the design process.

Experience – we have extensive experience of working with developers of all sizes, so you can be sure the solutions you get are both achievable on-site and deliver valuable cost savings.

Expertise – we are SAP trained and have full accreditation for the Code for Sustainable Homes, SBEM, BREEAM and PSI value calculations. We also work closely with manufacturers to ensure you benefit from their latest products straight away.

Responsiveness – we regularly review our service delivery, and are always keen to improve the service we deliver.
