Having successfully provided construction consultancy services for over 35 years, our track record is exemplary. The majority of our current projects are as a result of repeat business and over 80% of our new business is as a result of recommendation. We believe that this speaks volumes for the quality of our service, as some of our Client comments below will also attest to…

“Excellent service, excellent value, professional and local too. Helps sustain the local economy.”

Lee Bushell – WHH

“Very knowledgeable on matters relating to Health and Safety and always happy to assist.”

Ryan Hirst – Warrington Borough Council

Very professional and always take the lead on matters of CDM where engaged in this role”
