Check the tree and proposed work before excavation
Gate posts, foundations, tracks, drainage and cable routes can affect nearby trees as well as the entrance. Start by identifying the trees and discussing the proposed work with the local planning authority and a competent arboricultural adviser where needed.
Check Tree Preservation Orders, conservation-area status and relevant conditions on existing planning permissions. Do not assume permission for a gate authorises all work affecting a tree.
What a Tree Preservation Order can restrict
A Tree Preservation Order protects specified trees, groups or woodlands. Government guidance identifies prohibited activities without the authority’s written consent, including cutting down, topping, lopping, uprooting, wilful damage and destruction. It also explains that cutting roots can require consent.
The work, exemptions and procedure need checking for the actual circumstances. Consult GOV.UK guidance on protected trees and the relevant local authority before carrying out work.
Conservation-area trees need a separate check
A tree can be subject to conservation-area controls even where it is not covered by a Tree Preservation Order. Notification requirements and exceptions depend on the circumstances. Ask the council which process applies and allow for it before agreeing a start date.
A borough label or generic website statement cannot confirm the status of your tree. Keep the authority’s response, any consent and its conditions with the project records.
Give the adviser the full entrance layout
Show the proposed gate, supports, motor or track, power cable, drainage and paving changes. Include temporary construction access, storage and vehicle movements. An excavation outside the visible canopy is not automatically clear of roots.
Ask the arboricultural adviser and gate contractor to coordinate the required protection area, access restrictions and construction method. Do not substitute a simple trunk-distance formula or a permitted percentage of root loss for that assessment.
Agree the method and responsibilities in writing
The proposal should identify who will obtain information or consent, which work is permitted, the protection arrangements and any supervision required. Where the layout needs to change to avoid harm, update the gate drawings and quotation before construction.
This article does not prescribe air-spading pressures, root barriers or a universal foundation detail. Those choices need site-specific advice. Do not cut exposed roots or alter the agreed method to keep a gate job moving; stop the affected work and obtain advice.
Prepare the enquiry and compare the scope
Send the property location, photographs from accessible positions and a description of the entrance work you want. Share tree reports, council responses and existing plans if you have them. Ask which specialist work falls within the gate quotation and which needs a separate appointment.
Our gate quotation checklist helps identify exclusions. Discuss the gate project before commissioning equipment that may not fit the agreed protected-tree layout.
