We would not hesitate to contact them for similar projects in the future” – EnviroCentre, Glasgow "The success of our working relationship with Complete Weed Control (South Wales) has been thanks to a partnership approach and the use of long term contracts. This way of working combined with Complete Weed Control's new technology have played an important part in Cardiff's recent success in both 'Wales in Bloom' and 'Britain in Bloom'"

Mike Clark, Operational Manager (Parks and Bereavement) from Cardiff County Council “I find the contract manager and staff to be polite, knowledgeable and very helpful when extra advice is required. Nothing ever seems to be too much trouble. In my opinion, they provide a value for money, fantastic service which results in weed free streets and housing estates."

Environment Department, London Borough of Barking and Dagenham "I am writing to thank your staff, company and yourself for a First Class service at The University recently. Your staff were all very professional and efficient at what they did, the work was completed with no fuss and a great deal of enthusiasm. Furthermore they kept us informed of any issues or problems that had arisen during the day. All in all I would have no problem recommending your staff and company to other grounds managers with whom I am in contact."
