We have championed the sustainability of our designs for many years

For BTP sustainability is at the heart of everything we do – whether it’s our approach to designing buildings or the way we run our business.

All designers have a responsibility to consider the environmental impact their designs have, whether during construction, during or at the end of a building’s lifespan.

BTP is taking a leading role in monitoring and responding to the changes to the Building Regulations 2021 and Future Homes Standard, which aims for all new homes to be zero-carbon ready by 2025.

We promote a ‘fabric first’ approach to low energy design, minimising reliance on costly or complex technologies in the first instance, with stepped changes towards net zero carbon and Passivhaus standards depending on our clients’ aspirations.

Decarbonisation of the UK’s existing housing stock is also a critical milestone on the net zero path to 2050. BTP has qualified Domestic Energy Assessors (DEA) and PAS 2035 Retrofit assessors in-house that are working with clients to achieve compliance and qualify for funding under the Government’s Social Housing Decarbonisation Fund.

We offer a holistic sustainability service. Our specialist in-house team is working with clients on their sustainability strategies on their journey towards net zero carbon and comprises of:

  • Passivhaus Assessors
  • SAP/EPC Assessors DEA and OCDEA (for existing and new build dwellings)
  • Home Quality Mark Assessors
  • PAS 2035 Assessors

To help our clients adapt to the changes, we are holding a series of plain talking webinars and seminars running through our design approach. If you would like to book a webinar or seminar or just have a chat email us at
