Our customers give us their thoughts

Keith WebberEnergy & Utilities Manager, Dartmoor Multi Academy Trust

Without access to the energy consumption data we get from Stark we wouldn’t have been able to make accurate proposals for our bid to the scheme and prove how the use of LED’s and solar panels could benefit the overall energy performance of our sites.

Hyder MohammadHead of Sustainability, The Hillingdon Hospitals NHS Foundation Trust

Whether you are an Energy Manager or Financial Director, access to energy data is very, very important. Stark is very reliable to have that level of granularity of the data, helping us closely manage our energy consumption, carbon and finances.

Charles Pipe MScEnergy Manager, London Borough of Hounslow

Going forward we’re going to have a multitude of projects and without having Stark’s metering and Stark ID, I couldn’t do it with any degree of guaranteed granularity or accuracy.
