Read our excellent client reviews
We have used ck4 for a number of years across a number of various projects. They always deliver an excellent service regardless of the project, some of which are bespoke to the site. CK4 always deliver this service using their designated skilled engineers across a number of specific skillsets. The standard of workmanship, flexibility and professionalism are absolutely first class from project manager to engineer.
I would highly recommend ck4 for any FM and development works.

Allison Homes were recommended to ck4 initially for the HVAC work within our office fit-out project in Peterborough. The standard of their work and the response that we received from their team impressed and encouraged us to invite them to tender for the building and fitting out of the interior office space. Their project management and engineers have been exceptional – delivering all aspects of the building, electrical and mechanical elements on time and within budget. Recently, we required changes to be made to our training facility and engaged ck4’s interior design team who moved mountains to deliver from concept, through detailed design and to completion of an impressive training environment in a tight timeframe.
The whole of ck4 have been brilliant with their professionalism and can-do attitude.

We have worked with ck4 on a number of internal projects, and they continue to be our first choice. Our first venture with them was during Lockdown: we had to maintain social distancing within the workplace, and we made the decision to carry out a complete overhaul of our building, creating new and specific areas for staff, and dragging the building from the seventies, and into the 21st century.
We have since had 2 further large projects completed by ck4, all to the same exacting high standard that they themselves insist upon.
ck4’s team that attends site are each experts in their fields, they keep the client up to date on progress at all times, ensuring deadlines are met, and they are a friendly bunch – although some of the singing could do with a little more practise!
We also use them to design, manufacture and install ductwork to fit onto our air compressors to remove the waste heat from the plant room.
If we need any further works, they will be our first port of call, and we would have no hesitation in recommending them to anyone considering a building project.

We have now completed phase one of three of the air conditioning installation at Easton House and I would like to take this opportunity to feed back to you both on how it went.
The Team, I have never worked with any of the team before and I have to say what a pleasure it has been. I don’t believe I could have had a better Manager than Chris, his knowledge of the trade is second to none, and because we have had to be so sympathetic to the building (inside and out) his advice and understanding of the situations that have arisen has been exemplary, he has never hesitated in taking the time to explain things I have asked to know about or listen to ideas or concerns I have had. The HVAC engineers, again have been a pleasure to work with, from my point of view as a Facilities manager I could not ask for better, they are punctual, professional and easy to get on with, we discussed the day’s work every morning so we were all clear on the plan, but most importantly (for me) they stop if they came across a problem and we discussed it to bring it to an agreeable conclusion.
I can’t fault Adam at all, he has done so much for CIPS in bringing the House up to standard, his knowledge of the building and the systems in it is an equal to my own. Tom as all the others is a great lad and has the making of a great electrical contractor. have personally enjoyed phase one of this project, we have hit all the deadlines with no disruption to the planned working of the business, all but the unexpected amount of snow. The above team have been a pleasure to work with and I would not hesitate in recommending your team to anyone.
After working with the guys again on phase 2, I stand by everything I said after phase 1. It has just backed the statement up.

Serpentine Estates LLP owns Fleet House, a 40,000 square foot office in Hampton, Peterborough. We commissioned ck4 to carry out a complete refit of the HVAC system and a number of internal renovations. Throughout the four month project, CK4 were great to work with: diligent, thorough and attentive to the details. ck4’s staff and management were a pleasure to deal with on a personal basis. When our business calls for a similar project we would use ck4 again without hesitation.
Mark Richer
ck4 have undertaken several different projects for us on site. From the initial site visit to discuss our requirements through to completion of the work we have been impressed with their professionalism. Their project management was superb, and nothing was too much trouble. All the workforce on site were skilled, helpful, and polite.
Overall ck4 have been an excellent partner for our refurbishment projects.
Julie Barratt
I’d like to take this opportunity once again to say how fantastic you and your teams are and what a pleasure it is to work with you! I honestly feel full of confidence that you guys over at ck4 will continue to deliver exceptional service and go above and beyond as you always do.
