A member has emailed the following suggestions. The HoHp applies only if you live in Scotland, place of more enlightened laws! The other suggestions would apply anywhere.
An effective way to challenge the minimal and shoddy maintenance is to lodge an application to the HoHP but important to compile solid evidence such as Summer and Winter photographs, annual independent site audit by a professional landscaper and ensure they have sight of Greenbelt's current Written Statement of Services, involve local MPs and Trading Standards Support and for newer developments check if the Local Authority can take enforcement action for non-compliance with the title deeds / Written Statement of Services. Also, involving the Press is usually effective and form a resident's association to prevent Greenbelt picking off residents one by one. Easily the worst company I have ever had the unfortunate experience of dealing with, lots of false promises about doing the work, bullying and threatening tactics against legitimate complaints and would have sacked them years ago if possible. See West Myreton Resident web page which has done excellent work in tackling this nightmare of a company. --
