Andrew McColl

"National Energy Services Ltd (NES) is the UK’s home for independent energy assessors and low carbon building professionals.

For more than 30 years NES has championed the benefits of energy certificates for buildings. They will help us to cut our energy use and turn wasteful carbon-emitting buildings into ones with lower running costs and reduced environmental impact.

We are passionate about promoting the highest standards. That way people can have confidence in the energy certificates our members produce and confidence to act on the recommendations they provide – whether for the smallest house or largest office block."

NES owns and operates the NHER scheme and SAVA
