Energy Saving Trust

Complex custom .NET development


Energy Saving Trust (EST) is a social enterprise, with a charitable foundation, offering impartial advice to communities and households on how to reduce carbon emissions, use water more sustainably and save money on energy bills. The Scottish Government asked EST to manage a project to design and build a register for the collection and validation of Energy Performance Certificates (EPC) for all domestic and non-domestic buildings in Scotland.

This involved the migration of information from the existing domestic register together with the creation of a new register for non-domestic buildings. The timescale for project delivery was extremely challenging.


Bridgeall’s Microsoft accredited .NET development team were selected to deliver a software solution customised to meet the specific needs of the project. Working according to our mission of ‘exceptional software. assured’, the new combined register was designed, developed and deployed within six months.

The design team had to be extremely flexible, accommodating multiple third parties and frequent changes to the specification as the solution was being developed. It was critical that this additional functionality was incorporated into the system to allow new services to come on stream at a later date. This, however, added considerably to project complexity.

To manage this challenge, Bridgeall utilised an Agile development approach which proved to be extremely successful.


The customised software solution develop by Bridgeall plays a key role in the Scottish Government's drive to reduce the country's carbon footprint and meet the challenges of global warming. Circa 200,000 Energy Performance Certificates are generated annually from the new combined register.

Bridgeall Managing Director Stephen Beer said:

"With a very strong track record of managing complex software development projects to successful completion, we are delighted to have delivered certainty for the Energy Saving Trust."

Martin Hyland, Head of Commercial Planning, Energy Saving Trust said:

“The big challenge for Bridgeall was to convince us they had the capacity to deal with the complexity of delivering the combined EPC register, something that had not been done before. This was always going to be a tricky journey. We knew the destination but had no clear route to deliver a one-stop solution for homes and businesses. Bridgeall achieved everything we asked of them, and more. Importantly, the solution was delivered on time and on budget.”
