Our Services

Let us take the risk and stress out of your low energy project

We aim to provide our clients with services and products that have a longer view at their core – see our main services listed below.  However, if you’ve got a problem related to low energy building and it’s not here then give us a call – we’re always up for a challenge!

Design: Passivhaus

We are working as energy consultants on a huge range of Passivhaus and low energy developments from large scale commercial to self-build; our collective experience is unrivalled in the UK.

Design: Building Services

Services to match a low energy building shell.  We design building services that are simple, easy to understand and reflect the fabric-first approach.  Understanding both the fabric and the services means a building that dove-tails beautifully.

Design: Thermal Bridging

We are very experienced at thermal bridge calculations and provide a rounded service – not just undertaking the calculations but helping to identify what needs modelling, ensure they are incorporated in SAP or PHPP correctly and most importantly providing practical advice on how the design can be changed to improve the performance.


We offer a range of post occupancy testing and monitoring from coheating to energy consumption analysis.  Our emphasis is always on using this information to provide really useful feedback to the client and team.


We are Passivhaus certifiers, and have certified over 200 buildings to the standard.  We pride ourselves on helping the team through the certification procedure.


Getting an understanding of low energy design out to as wide an audience as possible is one of our key principles.  As well as our involvement in the CarbonLite programme, talk to us about training in all aspects of low energy design and construction.
