Matt Stanford-Evans2025-06-24Trustindex verifies that the original source of the review is Google. Recently we worked with TDI in order to design, build and install a mezzanine within a newly opened gym. After several quotes and meetings with other manufactures it was clear that TDI were the front runner. Their customer service, approach to problem solving and all round 'can do attitude', along with a willingness to support a start up business was and will always be greatly appreciated. The finished product is fantastic and everything ran like clockwork. They also turned the whole project around in record time! Super impressed and highly recommended. If you are looking for a solution then look no further than TDI Systems Ltd. Thanks again for everything. Andrew Brown2025-06-03Trustindex verifies that the original source of the review is Google. We recently had our mezzanine floor extended and also a complete renovation of our office space. Having had our original mezzanine erected over 10 years ago by TDI Systems, when it came to extending this further we had no hesitation in using their team again. The whole process was seamless. We needed this work done quickly to ensure minimal disruption to our business which was more than accommodated by Mark and his team. We made tweaks to the specification as the project progressed and these were met and dealt with efficiently and without any complaint. The whole job from start to finish was completed in 2 months, no mean feat considering the work that had to be completed. The end result is outstanding, transforming our workspace into a modern and functional environment for all. I can’t recommend this company enough, we received regular updates and transparent communication ensured we were always kept informed of the project progress and timeline. Luke McCreary2025-05-29Trustindex verifies that the original source of the review is Google. We recently partnered with TDI Systems for the design and construction of our new meeting rooms and staff canteen, and we couldn't be more thrilled with the results. From start to finish, the team demonstrated outstanding professionalism, technical expertise, and a genuine commitment to delivering high-quality work. The new meeting rooms are not only functional but beautifully designed—every detail reflects thoughtful planning and a clear understanding of our needs. The spaces are modern, comfortable, and equipped with the latest technology, making team collaboration and client meetings seamless and enjoyable. Equally impressive is our new staff canteen, which has completely transformed the way our teams interact during breaks. It's bright, inviting, and well laid out—creating a space that encourages relaxation and connection. The attention to detail in both aesthetics and functionality is evident throughout. TDI Systems stood out for their clear communication, flexible approach, and ability to deliver on time and within budget. They were always responsive to our feedback and went the extra mile to ensure everything was just right. We wholeheartedly recommend TDI Systems to anyone looking for a reliable, skilled, and forward-thinking construction and fit-out partner. They’ve truly raised the bar for what a workplace environment can be. Josh Lawton2025-05-22Trustindex verifies that the original source of the review is Google. We recently had a mezzanine floor installed in our warehouse by TDI Systems, and the experience was excellent from start to finish. Mark was refreshingly responsive and always easy to get hold of — a rare quality these days! Everything the team promised, they delivered on time and exactly as agreed. They were happy to answer all our questions throughout the process, and the installation itself was quick, smooth, and completely hassle-free. We’re very pleased with the outcome and wouldn’t hesitate to recommend TDI Systems to anyone looking for reliable, professional service. SilverLeaf Spaces Ltd2025-03-31Trustindex verifies that the original source of the review is Google. TDI were referred to us by a previous client. Mark @ TDI Systems was really easy to work with, planning a great mezzanine space for us. The process was seamless, the installation very professional, with the end result absolutely fantastic. Thank you! Gary Syrett2024-11-19Trustindex verifies that the original source of the review is Google. I was given Marks details from a neighbour and from the initial moment we spoke on the phone to the actual installation of our mezzanine, the service was first class. Very competitive price without compromising quality and only 6 week delivery from time of order. Highly Recommend and will use again in the future for sure! Mark Wiffen2024-11-19Trustindex verifies that the original source of the review is Google. TDI systems supplied and installed my mezzanine for the business, by far one of the best companies to deal with from design to installation by far! Have recommended to a few close by units and will continue to recommend to any customers going forward of mine admiring the mezzanine. Damien Kyley Woods2023-10-11Trustindex verifies that the original source of the review is Google. Have used TDI over a number of years on a number of assignments and major projects! The team, led by Mark, are exceptional and deliver on all their commitments. From design & concept to project delivery TDI and the team are consistent in their approach and always go above and beyond to deliver! Nothing is too much trouble and dealing with scope change (sometime no of us want) comes without a challenge. I would not hesitate to recommend TDI to any other organisation or individual who needs a one stop shop! steve jackson2023-10-11Trustindex verifies that the original source of the review is Google. We have used Mark and TDI for 4 mezzanines now and each time he has delivered at a great cost and on time. Great service and we have never been anything but happy with all the works carried out. Len Dopson2023-10-11Trustindex verifies that the original source of the review is Google. TDI Systems Ltd supplied and fitted a large MEZZ floor at our factory in double quick time, which was great because it hardly effected our day to day production. A few months later they completed a more difficult extension to this MEZZ floor, which was designed around our excisting laser cutting machines - We were so pleased with the result, and how professionally we were taken care of. I highly recommend TDI Systems! Len (LD Fabrications Ltd)

questions
Frequently Asked Questions
What is a Commercial Office Fit Out?
A commercial office fit out is the process of adapting an empty or outdated space into a fully functional workspace, ready for use.
What’s the Difference Between a CAT A and CAT B Fit Out?
A CAT A fit out is when you take an empty ‘shell’ of a space and add the functionality that makes it useable. For example, adding basic lighting, HVAC, and raised access flooring.
A CAT B fit out is when you add the finishing touches that make a space your own. For example, partitions and doors, furniture, and signage.
We carry out both CAT A and CAT B fit outs to an exceptional standard.
Do You Only Fit Out Mezzanine Floors?
No – we can fit out any space.
How Much Does a Commercial Office Fit Out Cost?
It depends on the size of the space, the prior condition of the space, and the type of fit out (CAT B fit outs are typically more expensive).
We provide a bespoke, itemised quote so you can see how much your commercial office fit out will cost before you commit.
How Long Does an Office Fit Out Take?
It depends on the size and complexity of the project.
We take pride in our experience, fast turnaround times, and clear communication. Our team will work hard to ensure your fit out is completed quickly without compromising on quality.
