Mike Corker

Director, Bolsterstone Wind Power

We have worked with other Environmental Consultants, but prefer the clear unambiguous way in which the Environmental Statement is prepared by Arcus as this makes a difficult subject easier to read by those not involved in the industry. The prices which Arcus offer are on a par with the industry and the service is first rate.

Cameron Smith

Former Offshore Development Director, Mainstream Renewables

The team were consistently impressed with Arcus’ attention to detail, quality, performance and price. Arcus has the right mix of experienced professionals and competent junior staff, all who were committed to achieving our high expectations. I would also note that the management team were quick to respond when issues arose with projects, and the relationship between my team and Arcus’ staff remained strong.

David Hardy

Solicitor, Eversheds

I consider the Arcus EIA chapters to be of a very high standard overall. The Arcus documents are coming across at the top end of the range of what I see so well done. I have very few comments to make. Certainly, in terms of passing the test for whether these chapters satisfy the EIA Regulations, I have no hesitation in saying they do.

Paul Kelly

Project Manager, Kelda Water Services

Kelda Water Services (KWS) - with support from Arcus - is developing a range of renewable energy technologies including wind, solar, anaerobic digestion, combined heat and power and hydro. KWS has an excellent working relationship with Arcus, lasting almost 4 years. Their attention to detail and clear presentation of information allows the complex nature of Environmental Impact Assessments to be readily understood. Arcus’ work is always of a high standard and delivered within agreed timescales and budgets. I would not hesitate to recommend them in any capacity.

Harry Bond

Former Director, Temporis Wind Energy Developments

Efficient, flexible, hard-working, trustworthy and enjoyable to work with are all characteristics of the Company and their employees, and this has allowed us to develop our own business quickly with their help. We have the highest opinion of this business and have no issue with recommending them to any third party who is looking to contract for their services.

Kari Khevenhüller

Director, Enel Viento

Enel Viento has worked with Arcus for 8 years, with great success. Arcus staff care about our projects and they advise solutions where needed. The company is small enough for their work to be personal to them, and large enough to provide all the required services we have needed from feasibility to construction through a single point of contact. I have enjoyed working with them, and would recommend them to other developers.

Neal Reid

Director, Blue Energy

I've worked with Michael on a number of projects over the past ten years or so. He knows his subject area inside out and back to front, and has answered questions off the top of his head which other consultants had been pondering for days. He is very easy to get on with, personable and friendly, and in all my experience working with him, has never missed a deadline. I would recommend him very highly.
