Speaking of his role, Darren said: “I am privileged to be the chairman of Interlay, especially as the Association has been a great tool for my company. Being backed by an Association such as ours is an influential ingredient for customers, who can feel immediately assured of our standards and working practice. I would urge any professional paving company to consider joining Interlay, as being able to demonstrate that you have been accredited by independent surveyors is an important stamp within the industry and could help to secure you more business.”

John Mcginlay -  Interlay Vice Chairman


Being vice chairman of Interlay is a role I take extremly seriosuly. I get great satisfaction being part of an independent association that is dedicated to promoting and maintaining the highest standards in the paving industry. I have been the paving industry for over 25 years and enjoy working alongside others who have the same passion for paving as I do. We are striving to promote an honest and professional paving industry that everyone can trust.

Sophia Glitherow – Interlay Administrator

I have been with Interlay since 2011 and provide all the administration for Interlay. I am also your first port of call should you have any issues. I also deal with any complaints shouldSophia FINAL edited they arise, which in my time with the association have been next to none. Throughout my time I have spoken to many members of the public, some of which have been distraught after having chosen the wrong person to do work on their property. Being someone myself who has done the exact same thing, I cannot urge members of the public enough to ensure they choose wisely when looking for someone to do work at their property. Quite often we tend to go for the cheapest quotes and if the quote is a lot lower than the rest alarm bells should ring. In my experience going for the lowest quote can sometimes cost you more than the more expensive one to put it right.
