Our Latest Case Studies

Our Latest Resources

The Diocese of Bath and Wells engaged BEE to support the development of its Net Zero strategy for clergy housing. BEE has provided valuable expertise and guidance alongside delivering medium-term, low-carbon plans for each dwelling, aligned with PAS 2035 and established heritage best practices. They demonstrated strong technical knowledge throughout and presented their findings in a clear, accessible format that is usable both by technical experts and non-specialists. In addition, they are a friendly and approachable team, making collaboration straightforward and constructive. This work presents particular challenges for older, listed vicarages, where BEE has shown a strong capability to develop sensitive and carefully considered proposals that respect the historic fabric while enabling sustainable improvements.

We have worked with BEE on a DESNZ-funded (WHSHF) upgrade of our housing stock, which includes a large number of listed properties and flats in conservation areas within historic areas of London and Bristol. They have consistently been helpful and knowledgeable critical friend throughout our project, assisting us and our framework contractor to negotiate the challenges of heritage assessment, planning consents and PAS2035 requirements. We would happily endorse them.

We’ve have been working with Building Energy Experts for a number of years now in the preparation of our Part L1 and O compliance requirements for our central London residential projects. From their Dynamic Thermal Modelling TM59 reports to their Energy Statements, their team have always reacted quickly and provided clear professional information, which have been instrumental in supporting the provision of all LPA documentation, along with ensuring we have all the technical compliancy details for our Permanent Works Packs. They are our preferred Energy Consultants.

Surveying an active shopping centre is logistically complex, but Building Energy Experts handled it with precision. Their report cut through the environmental variables to provide a clear distinction between maintenance quick-wins, like resealing doors, and the capital investment needed for insulation. It provided the exact technical evidence required to inform our roadmap to an EPC B rating and justify the retrofit budget.

In delivery of the Warm Homes: Local Grant programme in Shropshire, Building Energy Experts (BEE) have acted as invaluable partners to the Council. Their expertise in reviewing installer designs and liaising with our consortium of local installers has ensured the technical compliance and appropriateness of measures installed under the scheme.

The Council’s goal was to find a critical friend that ensures best practice and full PAS2035 compliance under schemes it delivers – BEE have brought this in spades, accompanied with a professionalism and pragmatism that has been indispensable in navigating the nuances and complexities of local authority led, domestic retrofit schemes. I would highly recommend engaging with BEE to any council or social housing provider considering an independent retrofit coordination model.
