We have had to engage with a lot of stakeholders for our project which has meant multiple changes to not only the scope of work but also the site location. Ryan has been very patient and flexible, adjusting estimates and quotes for the in-house and sub-contracted works to suit the changes we’ve needed to implement. I’m very pleased that he has stuck with us and continued to provide cost effective costings.

Thanks also go to Brian who has been able to guide us on the technical aspects of the work. The team have given us great confidence that they will continue to support us in the construction phase and help us to achieve our project milestones.

Connected Energy

Gull Wing bridge is a very important project for our company. We have been working with our trusted supply chain to deliver a successful scheme which will deliver a positive, lasting legacy in Lowestoft. High voltage infrastructure requires highly competent expertise and Maintech Power has partnered well with us to provide this service.

Farrans

I would like to take a moment to thank you and your team for all the hard work on the weekend’s shutdown.

It wasn’t the easiest with time constraints and testing switchgear, but your team acted very professionally, and it all went as smooth as possible so thank you for that.

Skanska

We have established an excellent working relationship with Maintech Power as our maintenance partner and trust the expertise and advice of its team, which has again proven to be beneficial for Muntons Malt.

As an energy intensive business, we are hugely committed to consistently reducing our impact on the environment and maintaining our established “Green Maltster” reputation. The installation of the low loss transformers is very much part of this strategy and we have already seen a significant reduction in carbon emissions.

Maintech Power ensured the process was incredibly efficient with a seamless transformer switch out, minimal production downtime and a rapid positive influence on our environmental credentials.

Muntons Malt

We just wanted to send a big ‘Thank You’ for the recent works completed for our HV switchgear upgrade. This work went very well and to plan – your work was well coordinated, smooth running, excellent team work and I can honestly say the best we have had in this respect for a good while.

I have many other works going on within our building, not as complex as this and many not to the standard you performed; this work is an absolute credit to you all and you really should be very proud of it.

So again, thanks to you all, keep up the good work, stay safe, and please pass this on to everyone involved.

Willis Towers Watson

You have been very professional and helpful in making these works go extremely smoothly with safety at the forefront all times.

CBRE

Maintaining a robust power network is essential for the smooth running of the entire university campus and this upgrade will support the current and future requirements. Maintech has been a trusted partner of the university for several years and we were pleased to award them this project following our thorough tender process.

University of Cambridge

On behalf of our management team, and on a personal level, I would like to thank your team for the excellent work carried out in the maintenance work here. They did an excellent job in leading the works and gave invaluable suggestions to our electricians throughout.
