Simon Spall MIET, Engineering Manager, 8build

MSL were pro-active and instrumental in completing London School of Hygiene & Tropical Medicine’s new Tavistock Place 2 building (TP2) as our MEPH contractor.

I would be confident working with them in the future.

Paul Terrett, Construction Manager, Blenheim House Construction

I have worked with MSL on two large and challenging projects in central London and I have always found their approach to be very positive and non-confrontational.
They have a great attitude to solving problems and the quality of their workmanship is outstanding – indeed, the neatness of their installation draws praise from all members of the project team. I would happily work with them again.

Simon Flatt, CEO, Flatt Consulting

A proactive team, providing a good quality of installation and very diligent in their activities and execution, as M&E Consultants this is very important to us

Gary Marshall, Building Services Director, SWECO

We worked with MSL on a large, complicated 100,000 Sq.Ft refurbishment project which was one of the most enjoyable projects for decades.

We worked together as one team and collaborated on all related design and co-ordination issues. The quality and attention to detail of the installation was exemplary and everyone on the team, demonstrated mutual respect for each other’s expertise.

It just shows you that with mutual collaboration, projects can be delivered with quality, on time, and on budget.
