Client Testimonials

SEM Facilities have been on our approved suppliers list for many years, and have carried out all aspects of Gas related works on our mobile portfolio to a professional high standard.

We have always found SEM to be reliable, trustworthy and extremely obliging, they work to our company processes and are flexible to the working situations.

Gerry Connoly


All of us at Porters are very grateful for your prompt attention to our boiler room breakdown. We were almost at the point of evacuating the building until your guys turned up at the door as arranged. As it turned out (despite our panic) the problem was relatively minor and you charged accordingly. Your billing reflected the fact and your honesty is to be commended.

Jon Porter


As an FM company we at IQPS strive to use high quality and efficient engineers. SEM Facilities have proved to be a call above the rest with their extensive knowledge of all systems irrelevant of size or age.

Their happy and confident approach to tacked anything we throw at them fills us and our clients with great confidence. Keep up the good work from all of us at IQPS.

Toby Ford


I can confirm our company has employed SEM over many years covering aspects of Gas and heating on contracts ranging in scale from a few thousand pounds up to £250,000. We continue to retain their services as we have found that their standard of works and professionalism is second to none.

We would have no hesitation in recommending them if you have any Gas or heating projects where a very high standard of workmanship is required.

John Putnam

Opus Facilities ltd

As contract manager for M and E across 4 University sites, I have struggled to find a reliable contractor to maintain the combustion plant. A colleague of mine recommended Surrey Environmental Maintenance to me 4 years ago and I haven't had a need to go elsewhere. I have found them to be professional and technically capable. Quoting and administration is quick and proficient. Always happy to respond to urgent calls, giving time scales and great advice as required.

The most important thing is their honesty, if they cannot do something, they will tell you.
