Our Core Services
Client Testimonials
What a great service you provided! As Self-Builders, with a great deal of red tape/bureaucracy to satisfy, you truly made this a real ‘value-add’ and reasonably priced exercise. We thought we were in reasonably good shape (having taken a lot of care and time on our build), but the checklist provided in advance of the test and the report post test, were really helpful in making improvements to the fabric of the building.
Tim Overton, Self-Builder – Air Tightness Test
We’ve worked with Building Energy Experts to support Part O compliance across our developments and have been consistently impressed with their service. Their team is proactive, knowledgeable, and always on hand to provide clear guidance throughout the design and compliance process. Their reports are thorough yet easy to digest, and their input has been instrumental in helping us meet regulatory requirements without compromising on design. The quality of their reporting and technical advice has made them a valuable partner to our team.
Sean Haplin, Technical Coordinator at Redrow Homes – Part O Dynamic Thermal Modelling
We’ve been very impressed with Building Energy Experts on all of our developments. We have found them to be very responsive to our queries and always happy to accommodate any further requests. We recently had an instance of an Energy Consultant going AWOL and urgently required a replacement Energy Consultant. BEE were able to quickly provide a quotation and were appointed within the same day of our initial enquiry.
Ryan Walker, Technical Manager at Woodstock Homes – Part L, F & O compliance services
Their information is always clearly represented, whether that’s in their Sustainability & Energy Statements submitted for Planning or SAP Input Summaries supporting their Design SAPs. I would without doubt, consider BEE, to be one of our preferred Energy Consultants.
Ambue work with Building Energy Experts across a number of clients across the South East. BEE’s assessors are capable and adaptable working across a range of homes and archetypes where they are thorough and diligent in their assessments. Stan’s easy and accommodating attitude puts Residents at ease to ensure they understand what he is doing to help improve the health and comfort of their home. Ambue will be working with BEE across a number of projects in 2025.
Rowley Maggs, Ambue – PAS 2035 Retrofit Assessments & advanced testing
I had a very positive experience working with BEE from a site perspective very helpful and quick to respond when I asked a question, turn around of results was very good. All in all I would use them again, very good.
Dominic Kevill, Site Manager at Woodstock Homes – Air Tightness Testing
Building Energy Experts produced a Sustainability & Energy Statement to support our planning application for 20 homes in Engine Common. They worked with our technical team to identify measures that would help energy savings across the development reduce residual carbon emissions. Despite the technical nature of the topic, the report was clear and concise and well received by the Council’s climate officers. I would happily recommend the team to other developers.
