What is a Section 211 Notice? When You Need One for Tree Work in Dorset
The Section 211 Notice is one of the most important — and most frequently overlooked — pieces of tree law in the UK. If your property sits within a Dorset conservation area and you want to carry out significant work on any qualifying tree, you are legally required to notify the council six weeks in advance. Failing to do so is a criminal offence. This guide explains exactly what the notice is, when you need it, how to submit it correctly and what happens during the six-week period.
The Legal Basis — Section 211 of the Town and Country Planning Act 1990
Section 211 of the Town and Country Planning Act 1990 provides automatic statutory protection for qualifying trees in designated conservation areas. Unlike trees with individual Tree Preservation Orders — which require formal consent from the local planning authority — the Section 211 regime works on a notification basis: you tell the council what you plan to do, and they have six weeks to decide whether to intervene.
If the council makes a Tree Preservation Order within those six weeks, you cannot proceed with the work without separate TPO consent. If no TPO is made — or if the council issues a written "no objection" response before six weeks is up — you can carry out the work as described in your notice.
The key point is that the six-week period must be served in full before any work starts. There is no exception for work that has already been planned, contracted or paid for. Starting work without a valid notice in place — even a day before the six weeks expires — constitutes an offence.
Which Trees and Which Areas Does It Apply To?
Conservation Areas in the Dorset and BCP Council Area
Both Dorset Council and BCP Council have designated conservation areas throughout their administrative areas. Within BCP's area alone, conservation areas include central Bournemouth, Westbourne, Southbourne, parts of Boscombe, Christchurch town centre, and areas of Poole including the Old Town and Lilliput. Dorset Council's conservation areas cover historic towns such as Wareham, Blandford Forum, Dorchester, Wimborne Minster, Sherborne and Shaftesbury, as well as a very large number of smaller villages and coastal settlements across the county.
If you are unsure whether your property is within a conservation area, you can check using the planning portals for BCP Council and Dorset Council — or simply call Clearcut Tree Surgery and we will verify your property's status before any work is planned.
The Tree Size Threshold
Section 211 Notice is required for any tree with a trunk circumference exceeding 75mm measured at 1.5 metres above ground level. This equates to approximately 24mm diameter — a modest threshold that covers virtually any established garden tree. Multi-stemmed trees and shrubs where individual stems are below this threshold may fall outside the requirement, though this needs careful assessment.
What Work Triggers the Notice Requirement?
The requirement applies to:
- Cutting down or uprooting a qualifying tree
- Topping or lopping the tree
- Any work to the roots that is likely to cause significant harm
- Any other operation likely to damage or destroy the tree
The requirement does not apply to:
- Dead trees and dead branches (though prompt notification is advisable in case of dispute)
- Trees already covered by a TPO — these follow the separate TPO consent process
- Trees below the 75mm circumference threshold
- Emergency works to prevent immediate danger to people or property — but you must notify the council as soon as possible after the emergency work
- Work specifically required by planning conditions attached to a planning permission
- Work to trees on Crown land in certain circumstances
How to Submit a Section 211 Notice in Dorset — Step by Step
Confirm your conservation area status
Check BCP Council or Dorset Council's online planning portal, or call the relevant planning department's tree officer. The designation runs with the land — it doesn't change unless the conservation area boundary is formally amended.
Check whether the tree has an existing TPO
If it does, the Section 211 process does not apply — you need a separate TPO consent application instead. Clearcut checks TPO status as standard before advising on the correct process.
Prepare your notice
The notice must be in writing and must include: the location of the tree (address and description or plan), a clear description of the work you intend to carry out, and your contact details. No prescribed form is required, but both BCP Council and Dorset Council accept electronic submissions via their planning portals.
Submit and record the submission date
Keep a copy of the notice and confirmation of receipt. The six-week period runs from the date the council receives the notice — not the date you send it. Electronic submission via the planning portal typically generates an automatic acknowledgement.
Monitor the notice period
The council has six weeks to make a TPO or issue a written objection. If you receive no response and no TPO is made, you may proceed with the work as described after the six weeks have expired. The consent lasts two years from that date.
Councils sometimes respond before six weeks: If the council's tree officer reviews your notice and decides not to make a TPO, they may issue a written "no objection" or "consent" response before the six-week period expires. This response allows you to proceed with the work immediately rather than waiting the full six weeks. This is most common for straightforward work on lower-category trees — and is one of the reasons that professional, well-presented notices tend to get faster responses.
What the Council Does During the Six Weeks
During the notice period, the local authority's tree officer reviews the proposed work, typically visits the site to assess the tree, and considers whether the tree merits protection via a TPO. The factors they consider include the tree's amenity value, visual prominence, public accessibility, ecological value, condition and life expectancy.
Trees of high amenity value — large, healthy, prominent specimens visible from public spaces — are more likely to have a TPO made against them than smaller, less visible or already-compromised trees. The council cannot prevent work from proceeding after six weeks simply by inaction — a TPO must be formally made within the notice period if the authority wishes to restrict the planned work.
