our clients review
I have been working with Aaron and Jourdan for over three years. We met on a job in East London and shared the same values and eagerness to do the job right. We have continued to work together thanks to their professionalism, knowledge and commitment across all their projects. The expansion they have gone through be organically aquiring more engineers and their dedication to training and development of their team is a credit to them both. They have built an amazing team. That's what makes them the first call I make whenever I have a project in London. It's always a pleasure working with them and I can trust that they will always do a fantastic job for me and my clients.
David Roberts
Managing Director, DR HIU Servicing
I have found your company and engineers to be at a very high standard, your engineers cant seem to do enough, we have had issues with parts failing within the units, your engineers have had to swap out, they have contacted our HIU manufacturer direct and requested the spare parts, this has always come through me, your engineers also have a great work rate and are very professional with their attitude towards getting the commissioning works complete on time. I would highly recommend your company in the future to carryout any HIU install or commissioning works.
Patrick Robinson
Senior Project Manager, Vital Energi
They did a fantastic job on one of my projects where the main objective was to improve the efficiency of the HIUs by reducing return temperatures. The results were excellent and the work was completed professionally and to a high standard. Over this time, I've found the team to be reliable, knowledgeable and easy to work with. They're always happy to explain any issues they come across and provide recommendations where needed. One thing I particularly like is that after every job they send a completion report with photos outlining exactly what has been done, along with any suggestions for further works if required. The engineers have experience working on a wide range of HIU manufacturers and it's clear they know their trade well. Overall, I've had a very positive experience working with Aaron and his team and would have no hesitation in recommending them
