The Knights Engineering Team

Client stories

Trusted by homes and businesses across Hertfordshire

We are proud of the relationships we build. Here is what some of our clients have to say.

Knights installed air conditioning across our offices with zero disruption to the team. Clean, professional and exactly on schedule. We now have them on a maintenance contract.

Sarah Whitmore

Facilities Manager, Stevenage

Our system failed during a heatwave and Knights had an engineer out the same day. They found the fault quickly and had us back up and running. Genuinely fast, honest service.

David Reynolds

Restaurant Owner, Hitchin

We had air conditioning fitted in our home and could not be happier. Tidy work, friendly engineers and the running costs are far lower than we expected.
