SBEM calculations are an essential part of building design and construction in the UK. They’re a legal requirement for most new buildings and major refurbishments, and they’re important for energy efficiency, building performance, and tackling climate change.

If you’re a housebuilder, architect, or property developer in the UK, it’s important to understand when you need SBEM calculations and how to ensure compliance with Part L of the Building Regulations.

Our sustainability consultants are a team of experienced, friendly, and knowledgeable experts well-versed in building compliance. Get in touch today for a free consultation or competitive quote.

Why work with us?


Our sustainability consultants have extensive experience in meeting regulatory requirements, yet work hard to go beyond mere compliance with the building regulations. We pride ourselves on delivering decarbonisation advice to help our clients build lower carbon, energy-efficient properties.


We reduce the amount of assumed data in each calculation to the bare minimum, meaning that our SBEM calculations are as accurate as possible. Conversations with clients are key to this process and our work improves each time we work on a new project, thanks to the collaborative approach we adopt with our clients.


Our office-based staff work hard to book all appointments as quickly as the delivery schedule allows.

We work on a two-week schedule, with the vast majority of SBEM calculations being delivered well within that window.


Our rate card prices for all services are reviewed regularly, so we’re confident that you won’t find a better service for a better price anywhere else.

If you think you’ve found one, we’ll either beat or match it.


Navigating the complexity of energy efficiency, decarbonisation, and building regulation updates isn’t easy. We’ve worked hard to explain a range of topics related to building compliance in plain English to help non-experts get the information they need.
