About Ascerta


At Ascerta we are committed to carrying out a professional approach to projects and are dedicated to producing the highest quality work to help our clients achieve their objectives as quickly and efficiently as possible

We have been supporting developers, architects and planning consultants with quality advice on landscape, trees and ecology for more than 20 years. Tree surveys, ecology surveys and landscape design are at the forefront of our portfolio of services.

Over the years we have been involved in a wide range of interesting projects, from ecology surveys for simple house extensions and a wide range of developments, to tree surveys for large scale developments of 2000+ units, infrastructure projects, housing association surveys, windfarms and airport safeguarding projects.

Our landscape design capabilities allow us to present a ‘joined-up thinking’ approach to projects and to provide positive solutions to issues for the benefit of the client.


Quality is at the forefront of everything that we do and we operate a quality management system with a core principle of continual improvement.

Fully insured with Public Liability cover of £2million, Professional Indemnity cover of £1million and Employers Liability cover of £10million, we take pride in our approach to Health & Safety, for which we have a record that is simply excellent.

Whatever your tree survey needs are, or whether you need an ecology survey or landscape design for a project, you can have confidence in our ability to deliver the results required.
