STSUK ensures a fully integrated service that covers the complete life cycle of Heating Ventilation Air-Conditioning Refrigeration (HVACR) equipment.

Our clients are typically great businesses in the leisure, hospitality, medical, and retail sectors, or they are residential customers, all predominantly in the northwest of England, but we seem to end up everywhere!

You may recognise a few of these challenges:

  • Frustrated with equipment outages that impact productivity and profitability;
  • Irritated by those who promise the Earth and then fail to be responsive;
  • Going dizzy due to astronomical installation, running, and repair costs;
  • Tearing out clumps of your hair because you are unable to serve customers due to equipment failure;
  • Struggling to find a reliable supplier who won’t let you down.

These are just a few examples, of course. In reality, we can understand and address almost any problem you might have; we’ve been around since 2009, and we built the business by listening to our clients.


We don’t just have technical expertise; we listen to what matters to you.
