    Thomson Customer Testimonials – Ecology Services

    An excellent experience - Thomson provided exactly the service we required in a very cost effective and timely manner.

    Project Manager, Building Contractor

    Thomson’s involvement as part of the delivery team was key to producing an end product that both looked great but that also met with the design criteria, ensuring the scheme will continue to perform into the future.

    John Sullivan, Senior Asset Manager, Eskmuir Group

    One of Redrow’s placemaking principles is the creation of new or enhancement of existing wildlife habitats. We have worked closely with Thomson on a number of initiatives to ensure that the local wildlife has a suitable environment during and post construction.

    The project was managed professionally, with the required updates performed clearly, concisely and on time. The field work was delivered to a high standard, with surveyors communicating and presenting themselves professionally – important as they were also representing our organisation; the quality of the fieldwork was first-rate.
