Client Feedback

We have employed Prime’s services in the capacity of M&E Building Services Commissioning
Managers over many years. From pre-construction M&E Commissioning studies and onwards
through construction stage to practical completion and final hand-over, I have found
Prime’s knowledge and experience a great asset to our project delivery teams. Currently
Prime have an on-going involvement at our Television Centre (TVC) residential project, the
former BBC Television Studios at White City, London.

Prime have provided us with reliable M&E Commissioning support and I would recommend
their professional services.

We are working with Sam Herbert, Director of Prime, on two of our schemes which are Friary Park
(The Verdean) and Whitechapel (Silk District) and the appointment is for the Overseeing the District
Heat Networks and validatiing from Design through to Handover which includes review of
methodology before the works begin, commissionability to the project phased requirements and
witnessing the systems being treated and tested.

Prime have formed a very professional relationship with MAL and are a key supply chain partner
moving forward as we continue to learn and grow to achieve high and efficient Mechanical Heating
Systems on our schemes and provide great homes for our residents. I would recommend their
professional services.

– Sat Lola, Mount Anvil Ltd

We have worked alongside Sam Herbert, Director of Prime, across a number of projects, these
include the following – Barts Square Phase 1, Barts Square Phase 3, 33 Charterhouse Street, Chiltern Academy, Royal London Hospital and Cleveland Clinic.

The above projects span almost 6 years, and, in this time, we have developed a strong relationship. Initially starting off with a focus on commissioning management, PRIME have now shown they can deliver high-end hands-on commissioning services across a range of systems. This has in some cases been combined with their established
commissioning management strategies to deliver a unique scope of services that have benefited SES and our clients over recent years.

As always PRIME have operated professionally, diligently and with a thirst to problem solve – going the extra mile to understand, resolve and learn from issues as they arise.


PRIME, working for SES, have been a key stone in our relationships with clients and their commissioning teams which have proven crucial in delivering the projects listed above.

We will be very much looking to partner with PRIME on a number of current and future opportunities.

– Matthew Sedge, SES (Engineering Services) Limited

We have worked alongside Sam Herbert and his company Prime Environmental services over the past 4 years on several
projects including St Barts Phase 3, 33 Charterhouse Street and more recently on 100 Newbridge Street.

Sam and Prime Environmental Services have proved to be professional and proficient with their delivery of commissioning,
commissioning management and plant validation works associated with the MEP services design.

Working in conjunction with our own design and commissioning consultant teams on various projects, Sam and Prime
Environmental Services have played a key role in the successful handover of our projects.

I would recommend Prime Environmental Services for their professional, helpful and pro-active approach in the delivery
and handover of their service
