Astill Treecare works independently of any tree surgery contractors, providing assurance to our clients that there is no financial gain for us to recommend tree works unnecessarily.

We have established good relations with many tree contractors, consultants and other land-based professionals. In this regard, Astill Treecare is happy to provide recommendations (upon request) for other professionals operating in your area from which clients can seek competitive quotes.

Astill Treecare shares the office and resources with a group of independent professionals, collectively called Canopy Land Use (forestry and agricultural ecology consultants). Click here to find out more.

During the initial enquiry we will ask you for some more detail about your trees and what you wish to achieve. For larger tree populations, it may be necessary to make a preliminary visit and discuss your objectives on site. Once we have established what you aim to achieve, we shall prepare a clear proposal stating:

what we will do for you,

when it will be completed by

what we will charge

For urgent tasks, we shall agree a deadline with you and stick to it.  Non-urgent tasks may take a little longer but we will still agree a realistic timeframe so you are always kept in the picture.

To ensure that there are no hidden or escalating costs, we aim to provide a fixed quote based on the information you have provided or we have gathered.  Once you have received a proposal and quote from us, we will always ask for a written instruction (email) before we proceed.

Astill Treecare does not currently charge VAT, keeping prices lower for non-VAT registered clients.


Astill Treecare holds £1 million professional indemnity insurance and £5 million public and product liability insurance. Click here

We are insured to provide professional arboricultural advice. We do not carry out tree surgery and it follows that we don’t hold cover to for tree surgery work. In this regard you are advised to check that if you are paying for advice from a tree surgery contractor, that they hold the relevant professional indemnity insurance.
