Introduction
A BS5837 tree survey is usually the first thing a Glasgow planning officer or main contractor asks for once trees sit on or near a development site -- it sets out which trees can be retained, where Root Protection Areas need marking before machinery arrives, and what has to happen if a tree can't stay. Leaving it until late in the design process is one of the more common ways a Glasgow commercial project ends up with a stalled application or an unplanned visit from a council tree officer partway through the build.
Where the survey recommends removing, reducing or clearing trees to make way for the build, that physical work is carried out as a separate job -- our commercial crown reduction and thinning and development site clearance teams pick up from wherever the survey and protection plan leave off.

- Final inspection and discharge report confirming no root or crown damage, for submission to the council to close the planning condition
Not Included / Costed Separately
- Physical tree work the survey recommends -- felling, crown reduction or pruning -- is scoped and quoted separately once retention decisions are agreed with the council; see our commercial crown reduction service
- Stump grinding and site clearance once a tree has been removed, covered through our commercial stump grinding and site clearance services
- Supply and planting of replacement trees where a planning condition requires them
- Ongoing amenity tree management once the development is complete and the planning condition has been discharged
How a BS5837 Instruction Runs From Enquiry to Discharge
- Initial enquiry and site details: We take basic details of the site, the proposed works and the planning stage you're at, so the visit can be scheduled with the right amount of time -- a single-tree domestic survey and a multi-tree commercial site need different lengths of visit.
- Site walkover and tree assessment: An NPTC Professional Tree Inspection qualified surveyor visits the site, records species, dimensions, condition and retention category for each relevant tree, and measures the ground for Root Protection Area calculations.
- Constraint plan and BS5837 report: The findings are drawn up as an AutoCAD constraint plan and written report showing which trees can be retained, where Root Protection Areas fall relative to the proposed layout, and what mitigation is needed for any tree the scheme can't accommodate.
- Tree protection plan and barrier installation: Once permission is granted, we specify and mark the protective barriers and exclusion zones the contractor needs in place before any machinery, materials or site cabins arrive.
- Monitoring through construction: Agreed-frequency visits check that barriers and Root Protection Areas haven't been disturbed, and flag anything that needs correcting before it becomes a compliance problem.
- Completion inspection and discharge: A final inspection confirms no root or crown damage has occurred, and a discharge report is prepared for the council so the tree-related planning condition can be signed off.
What Each Stage of the Planning Condition Costs to Clear
Because BS5837 work is tied to a planning condition rather than being one flat job, the cost tends to land in stages rather than as a single invoice. The survey itself, needed before the application goes in, typically starts from £450 (+VAT) for a straightforward site and rises to around £1,200 for larger tree populations or a more complex constraint plan. Where a feasibility check is useful before committing to the full survey, it's usually rolled into the survey fee, though larger or more complicated sites are priced separately. Once permission is granted, the tree protection plan that has to be in place before the condition can be worked towards discharge is usually from £350, monitoring visits through the build are from £85 each, and the completion inspection that closes the condition out is from £200 -- or included where a monitoring programme has run throughout. These are realistic starting points rather than a fixed price list: the number of trees, site access and how many monitoring visits your specific planning condition calls for all change the final figure, so a firm quote needs a site visit.
Categorisation a Planning Officer Won't Query
A BS5837 report only does its job if a planning officer accepts the categorisation and Root Protection Areas without sending it back for more detail, and the assessor's own background is what usually decides that. Site assessments are carried out by NPTC Professional Tree Inspection qualified surveyors, and the same team holds the wider NPTC and Lantra certificates covering felling, aerial rescue, rigging and dismantling. A retention category or mitigation proposal written by someone who also carries out that work day to day tends to hold up better once it's under scrutiny, because it's based on what's actually achievable on site rather than a desk judgement a contractor has to reinterpret once the condition needs discharging. All work, both the survey and any tree work that follows it, is carried out to British Standard by a fully insured team, and quotes are free and no-obligation.
Which Council Planning Department You're Working With
Which planning authority is reading your BS5837 report changes what they'll expect from it, and Glasgow Trees works across eight council areas along the M8/M74/M77/M80/A82 corridors -- Glasgow City, East Dunbartonshire, West Dunbartonshire, Renfrewshire, East Renfrewshire, Inverclyde, parts of South Lanarkshire, and Stirling and Falkirk around Bo'ness -- so reports and constraint plans are put together with the right authority's format and level of detail in mind from the outset. Trading from Clyde Offices on West George Street puts the team close to Glasgow City Council's planning department and within easy reach of the riverside and brownfield land a lot of the city's current redevelopment sits on -- former industrial ground along the Clyde waterfront and older commercial plots bordering the M8. Trees on that kind of site are often self-seeded rather than formally planted, which makes Root Protection Area calculation less straightforward than on a site with a mapped amenity planting scheme: root spread has to be judged from soil type and growth habit rather than assumed from planting records, and trial pits are sometimes the only reliable way to confirm it before a constraint plan can go to the council. The same judgement applies on suburban infill plots at the city's fringe, where a single mature tree close to a boundary can decide where an access road or foundation footprint is allowed to go.
Which Stage of the Planning Condition You're Paying For

Frequently Asked Questions
What's the difference between BS5837 and BS3998, and do I need both?
BS5837:2012 is the survey and development standard -- it's what produces the tree categorisation, Root Protection Areas and constraint plan a planning authority wants to see. BS3998 is the separate standard covering how any tree work itself should actually be carried out, whether that's a crown reduction to create clearance for scaffolding or the removal of a tree the survey couldn't justify retaining. Glasgow Trees carries out both the BS5837 assessment work and any BS3998 tree work that follows it, so the two standards sit alongside each other rather than one replacing the other.
Who actually carries out the tree survey - is it a qualified arboriculturist?
Yes. Site assessments are carried out by NPTC Professional Tree Inspection qualified surveyors, and the same team holds the wider NPTC and Lantra tree-work certificates covering felling, aerial work and rigging. That matters in practice because the person who decides whether a tree can be retained also understands what protecting it, or working safely around it, actually involves on site -- rather than a desk-based categorisation that a contractor then has to reinterpret.
Does a small extension or driveway need a BS5837 survey, or is this only for big commercial developments?
It depends on how close the works are to a tree, not the size of the project. A single-tree survey for a domestic extension or new driveway is a much lighter, cheaper instruction than a multi-tree commercial report, but the same principles apply -- categorisation, a Root Protection Area, and a note on how the foundations or access route will avoid it. If you're not sure whether your project needs one, a quick site visit will confirm it either way before you commit to a full survey.
What happens if the survey finds a tree can't be retained - does that stop the project?
Not usually. The Arboricultural Impact Assessment sets out the justification for removing a tree and the mitigation -- typically replacement planting -- that the council will expect as a condition. It slows things down if it's raised late, but it rarely stops a project outright provided the case is documented properly. The removal work itself, once agreed, is then scoped and quoted as its own job rather than being bundled into the survey fee.
What should I do if a protection barrier gets knocked or moved during construction?
Stop work in that area straight away and get in touch before continuing. A barrier that's been moved or damaged inside a Root Protection Area is exactly the situation that leads to enforcement action if it isn't corrected quickly -- root or trunk damage inside that zone is often what a council penalty is actually based on, not just the fact a barrier moved. Reinstating it properly and recording that it happened is far cheaper than leaving it and hoping it isn't noticed at a site visit.
Can trees near the site be pruned instead of removed to make room for construction?
Often, yes. A crown reduction or targeted pruning carried out to BS3998 can create the clearance needed for scaffolding, plant access or roof eaves without touching the Root Protection Area or affecting the tree's retention category. It's usually quicker to arrange and cheaper than removal plus mandatory replacement planting, and it keeps an established tree -- which is worth more to a scheme's landscaping and planning case than a newly planted replacement.
Do I need a new BS5837 survey if construction is delayed after the original one was done?
There's no fixed expiry date written into the standard, but most planning authorities and surveyors treat a survey as unreliable once a meaningful amount of time has passed -- commonly more than around two years -- because tree condition and Root Protection Areas can genuinely change in that time. If your build has stalled since the original survey, it's worth getting it reviewed before construction starts rather than assuming the categorisations still hold; a review is usually far cheaper than a fresh full survey.
Get Your BS5837 Survey Booked Before It Becomes a Planning Delay
The longer a BS5837 survey is left, the more likely it is to surface a conflict late in the design process, when moving a Root Protection Area or reworking a foundation layout costs far more than it would have at the outline stage. Get in touch for a free, no-obligation quote and a site visit can usually be arranged well before your planning submission deadline.
