Sustainability By Design Ltd

Sustainability By Design specialises in optimizing the energy performance of buildings. We are dedicated to working with construction companies, developers, and architects to create sustainable solutions that meet building regulations and drive resource conservation.
Unlike other energy assessors, we offer a full support service throughout the project and take responsibility for ensuring ALL energy efficiency requirements are met.
Free up your project team to focus on what they do best and take the guesswork out of compliance.
Industry experts
You'll have a dedicated specialist with 15+ years of industry experience to inform building design from start to finish. No more guesswork with how design tweaks and VE could impact building performance or Part L compliance.
Early engagement brings the most opportunity and all options for passive design, reducing emissions and improving building performance can be explored.
We offer practical solutions for energy performance in a language you can understand.


Never miss a milestone
We don't operate on a 'check and forget' basis. This approach can often lead to poorer performance outcomes and worse still, completed buildings that are no longer compliant when it comes to producing the As Built energy model.
We take ownership of the energy performance of your building, acting as an additional project team member, regularly checking in and attending design meetings to ensure no design changes made during construction are missed.
This leaves the rest of the project team to do what they do best, freeing up resource.
We guarantee success
We offer a 100% money back guarantee on our fees if there are any project delays due to energy performance issues. No more costly delays to project completion or building handover.
We have saved clients ££££s in avoiding project delays and coming up with cost effective solutions to energy performance issues.

Testimonials
Paul Chappell, Denny's Construction
Sustainability By Design have always been extremely helpful and prompt in the preparation of SAPs, SBEM and EPC information necessary for the successful handover construction projects.
Shelley was pivotal in providing calculations and advice, which raised a recent BREEAM project, from a “Very Good” to “Excellent” rating.
We would have no hesitation in recommending the services of Sustainability By Design.
Maria Demmon, Milton Keynes CC
Shelley provided specialist advice on the sustainability elements of our project. Her assistance helped to de-mystify both the language and the process, reflecting her understanding of the Council’s specific requirements and aims of the project. Working within tight timescales, she assisted during the design and development stage and worked with other Council colleagues to provide the data to apply for COF grant funding.
I would not hesitate to recommend working with the Sustainability by Design Team!
