Our Story

Our Story

KMS was built to do things better.


No vague pricing. No missed appointments. No cutting corners. Just expert air conditioning, honest advice and a team that takes pride in every installation.

As a family-run South London company with more than 20 years of industry experience, we have grown through recommendations, repeat business and long-standing customer relationships. Today, we work with homeowners, landlords, offices, shops, restaurants, pubs and commercial sites across London and the South East.


Our F-Gas certified and REFCOM-registered engineers install, service and repair everything from discreet single-room units to multi-room systems, cellar cooling, refrigeration and complex commercial HVAC.

Whatever the project, our approach stays the same: turn up, get it right and leave you with a system built to perform.

Every project we undertake is guided by our core values of quality, professionalism, and customer satisfaction. We believe that a well-built roof is more than just a structure – it's a symbol of safety, security, and pride for homeowners and businesses alike. That's why we approach each job with meticulous attention to detail, using only the highest quality materials and employing skilled craftsmen who take pride in their work.

But our mission extends beyond the roofs we build. We are dedicated to making a positive impact in the communities we serve, whether through supporting local initiatives, promoting sustainable practices, or contributing to charitable causes. We believe that by investing in our communities, we can create a brighter future for generations to come.
