Discharging a tree protection condition without delay

7 min readBy PlanScope Editorial Team

A tree protection condition is satisfied by evidence that the exclusion zone existed before work started. Submit the package in the order the tree officer reads it.

A tree protection condition is discharged on photographs, not on promises. The council's tree officer wants to see fencing standing in the right place before anything else happens on site, and the fastest way to lose three weeks is to submit a method statement without evidence that the Construction Exclusion Zone exists on the ground. Discharge a tree protection condition efficiently and you submit a package that lets the officer approve without a site visit, or with one short visit already arranged.

The condition itself usually tells you exactly what is wanted. Most people read past it.

What the condition normally requires

Typical wording asks for three documents and one event. An arboricultural method statement, a tree protection plan and details of protective fencing, all in accordance with BS 5837:2012, together with confirmation that the fencing has been installed before any equipment, materials or machinery are brought on to site.

That last clause is the operative one. It means the fencing has to be up before the works start, which in turn means the discharge application has to be made while the site is still empty. A condition drafted this way cannot be satisfied retrospectively in any honest sense, because the evidence required is evidence of a state of affairs that existed at a particular moment.

Where the condition also requires arboricultural supervision, expect a second stage: a schedule of site visits agreed in advance and certificates issued after each one.

Documents to submit and in what order

Assemble the package in the order the officer will read it.

  1. A covering letter quoting the application reference, the decision notice date and the condition number, and listing the documents enclosed against each limb of the condition.
  2. The tree protection plan, at a legible scale, showing every retained tree with its reference number, the Root Protection Area drawn as a plotted shape rather than a circle where the shape has been adjusted, the fence line, any ground protection and the access and storage areas.
  3. The arboricultural method statement, covering works within or adjacent to any Root Protection Area, the construction method for anything inside it, the service routes, the supervision schedule and the order of operations.
  4. The fencing specification, either the default in BS 5837 or a stated alternative with the reason.
  5. Dated photographs of the installed fencing, with a location plan keyed to the camera positions.
  6. Where the layout has changed since the tree survey was prepared, a short note confirming the Root Protection Areas have been rechecked against the current drawings.

Keep the tree numbering identical across all documents. An officer comparing a plan that calls a tree T14 with a method statement that calls it G3 will ask for a resubmission rather than work it out.

Photographic evidence of installed fencing

The photographs do more work than any other part of the submission, and they fail for the same handful of reasons every time.

Take them after the fence is complete and before any plant arrives. Include a wide shot showing the fence line in relation to the tree and the building line, and a close shot showing the construction of the fence itself, so the uprights, the framework and the mesh are visible. Photograph the signage. Take one image from each corner of the exclusion zone. Keep the original files with their metadata rather than pasting compressed copies into a document, and put the date in the caption anyway.

The default specification in BS 5837:2012 is a fence of welded mesh panels mounted on scaffold framework, not free-standing panels on feet, and the difference is visible in a photograph. Where the site requires something else, say so in the method statement and give the reason before the officer asks.

Ground protection is often forgotten. Where any part of a Root Protection Area has to be crossed or used, the protection has to be shown and photographed too.

Supervision certificates and records

Where supervision is required, agree the hold points in writing at the start. The usual set is installation of fencing, any excavation within a Root Protection Area, installation of no-dig surfacing, service trenching in the vicinity of retained trees, and removal of protection at the end.

After each visit, the arboriculturist issues a short certificate: date, site, trees inspected, what was observed, whether the works accorded with the method statement, and any remedial action. Send them to the council as they are issued rather than in a bundle at the end. A council that has been receiving certificates through the build is far less likely to object at the final discharge.

Keep a site record too. The contractor's daily record should note when protection was moved, why and on whose authority, because a fence that moves without a record is the single most common cause of an enforcement conversation. Keeping a tree through a build is a management problem as much as a technical one, and retaining a tree through a construction programme covers the day-to-day side.

Timing against the start on site

Work back from the date the first machine arrives.

Step Lead time
Arboriculturist produces method statement and protection plan Two to three weeks from instruction
Fencing installed on site One to three days, longer on a constrained frontage
Photographs taken and package assembled One day
Council determines the discharge application Up to eight weeks under article 27 of the Development Management Procedure Order 2015
Tree officer site visit, if required Within the eight weeks, but booked early

There is a chicken and egg problem in that table and it is worth naming. Installing the fence is itself an operation on site, and on a tight site it may require deliveries. Installing protective fencing is not a material operation that begins development under section 56(4) of the 1990 Act, so it does not implement the permission, but it does need to happen before anything else. Say so explicitly in the covering letter so nobody reads the photographs as evidence of an unlawful start.

Nesting birds add a second constraint. Vegetation clearance during the March to August breeding season risks an offence under the Wildlife and Countryside Act 1981, so any clearance associated with setting out the protection needs checking first.

Common reasons a discharge is refused

Six recur often enough to check against before submitting.

A tree protection plan showing Root Protection Areas as circles where the survey recorded an offset or irregular shape. A method statement that describes protection but not the construction method for the works actually proposed inside the Root Protection Area. Photographs with no date and no location plan. Fencing that plainly does not match the specification submitted. A supervision schedule with no named arboriculturist and no contact details. And a package that refers to a superseded layout, which is the one an officer spots fastest because the fence line does not match the approved site plan.

Where street trees or verge trees outside the site boundary are affected, the highway authority is a separate consultee with its own requirements, and street trees, highway works and utility trenching sets out how that interacts.

When the layout changes after approval

A layout change moves the fence line, which means the approved tree protection plan no longer describes the site. Do not simply build to the new layout and hope.

Two routes exist. Where the change is small and the protection is unaffected in substance, a note to the tree officer with a revised plan is often accepted as a variation to the approved details. Where the change moves construction into a Root Protection Area that was previously outside it, the approved details have to be resubmitted, and a non-material amendment or a variation of the relevant condition may be needed as well. Either way, tell the officer before the fence moves. A retrospective explanation carries none of the weight of a prior notification, and where planting is also affected the approved Landscape Strategy will need updating to match.

Frequently asked questions

What documents does a tree protection condition usually require?

An arboricultural method statement, a tree protection plan and a fencing specification, all prepared in accordance with BS 5837:2012, plus confirmation that the fencing is installed before equipment, materials or machinery arrive. Where supervision is required, a schedule of site visits and certificates issued after each visit follow as a second stage.

What should the fencing photographs show?

A wide shot of the fence line in relation to the tree and the building line, a close shot showing the uprights, framework and mesh, an image of the signage, and one view from each corner of the exclusion zone. Keep original files with their metadata, caption them with the date, and key them to a location plan.

Does installing protective fencing start development?

No. Installing fencing is not one of the material operations listed in section 56(4) of the Town and Country Planning Act 1990, so it does not implement the permission. Say so in the covering letter, because otherwise the photographs can be misread as evidence that work began before conditions were discharged.

Why are tree protection discharges refused?

Most often for Root Protection Areas drawn as circles where the survey recorded an irregular shape, a method statement silent on the construction method inside the protection area, undated photographs without a location plan, fencing that does not match the specification, a supervision schedule with no named arboriculturist, or a package referring to a superseded layout.

What happens if the layout changes after the details are approved?

The approved tree protection plan no longer describes the site, so tell the tree officer before the fence moves. A minor change with no substantive effect on protection is often accepted as a variation to approved details. A change that brings construction into a Root Protection Area needs resubmission, and possibly an amendment to the permission.

When should supervision certificates be sent to the council?

As each one is issued, rather than as a bundle at the end. A council receiving certificates through the build has visibility of what happened and is far less likely to raise objections at final discharge. Agree the hold points in writing at the outset, covering fencing, excavation, no-dig surfacing and service trenching.
