Having Regal Environmental Systems handle the installation and maintenance of our heating, air conditioning and heat recovery systems throughout our group, has meant a real reliable professional support for our company over many years. Their team are not only smart and presentable, but also very knowledgeable and approachable making it easy to discuss any issues. They are consistently reliable, arriving as scheduled and nimble when we need urgent support. We would highly recommend their services.

The Portway Centre has used Regal Environmental Systems Ltd for over 10 years now. Their advice and expertise has allowed us to ensure all our Tenants and Clients have the best environmental facilities available. Graham and Stuart are always available to discuss projects and advise us. They go over and above in fitting in with our timetables and our Tenants. They have proved themselves cost effective and reliable, and I would not hesitate to recommend them for commercial or even residential properties.

In the field of precision engineering it's as much about the comfort of the engineers as it is about the materials we use to work with. Since installing Regal heating and cooling our engineers’ concentration is better, the materials are more stable resulting in higher efficiency and less waste of time and material.

Harwoods Group have contracted their entire dealership HVAC maintenance to Regal since 2019 and during that time have always found them to be reliable and professional with a positive can-do attitude, quick to react if issues arrive and always on hand to provide advice when needed. The company has a friendly family feel, which makes doing business with them a pleasure and here’s to many more years working together.

James Money
Facilities Manager at Harwoods Group

It's simple. Customers spend more time and money in an air conditioned retail environment. Since installing Regal air conditioning systems our turnover has increased during summer months, and the staff are comfortable at work.

Mr Bob Davidson

Regal have been an excellent partner over the last 15 years providing critical support to our Datacentre cooling infrastructure. First class servicing and always available in the event of an issue, they really care about our equipment as much as we do.
