Net Zero UK is a division of S I Sealy & Associates Ltd.

S I Sealy, which was formed in 1949 as a building services engineering design consultancy, has, for many years, supported clients in their objective to achieve Net Zero buildings.

We invested in sophisticated building and energy modelling software and upskilling our team to advise clients on the best ways to achieve Net-Zero.

Supporting clients in the drive towards Net Zero is such a key part of our business, that we have launched this as a division with its own identity, whilst still being intrinsic to S I Sealy with the same ethos of high-quality advice and service.
