Introduction
If you own or manage a commercial property in Glasgow with trees on or near the site, a professional tree survey is often the quickest way to satisfy an insurer's renewal conditions or a council planning department before work starts nearby. Glasgow Trees carries out arboricultural assessments to British Standard BS3998, with reports written to the BS5837 category system that insurers, mortgage lenders and planning officers already recognise. This is specifically the survey built around a third party's paperwork requirement - an insurer's renewal terms, a lender's condition, a planning submission - rather than a general once-over of how your trees are doing; if there's no external deadline behind the request, a shorter conversation with us first usually saves you paying for reporting detail the job doesn't need. Whether you need a single-building insurance check or a full tree inventory across a multi-site portfolio, the survey is scoped to match what the report actually needs to demonstrate, not sold as one flat package.
Key Selling Points
- Free, no-obligation site visit before any quote
- NPTC Professional Tree Inspection qualified assessments
- Reports written to BS3998 and the BS5837 category system
Where the Survey Fee Stops and Separate Costs Begin
- On-site inspection of each tree, recording species, age class, condition and BS5837 category (A, B, C or U)
- A written report suitable for submission to insurers, mortgage lenders or the local planning authority
- Root protection area (RPA) calculations and a constraint plan where construction or extension work is planned nearby
- GPS-logged tree locations and a full inventory for larger sites with multiple buildings or extensive tree cover
- A prioritised management schedule flagging which trees need attention first and roughly when
- Photographs of any notable defects, decay or damage referenced in the written findings
Not Included / Costed Separately
- Any tree work recommended in the report - pruning, felling, cabling or bracing - is quoted and invoiced separately from the survey fee, not bundled into it
- Statutory council fees for planning applications or Tree Preservation Order consent are the client's to pay; we prepare and submit the paperwork, but we don't cover the local authority's own charges
- A second site visit after the original inspection - following a storm, a dispute with an insurer, or a change of tenant - is treated as a new instruction unless you've taken out one of the annual monitoring programmes
- Where root activity looks like it may be contributing to subsidence, our report flags it and points you toward a structural engineer; an arboricultural survey identifies the tree-related risk but doesn't replace a structural engineer's foundation report
- Trees outside your ownership - a neighbour's tree overhanging your boundary, for example - can be noted in the report, but we can't inspect or recommend work on them without that owner's agreement
- A general condition check with no insurer, lender or planning deadline behind it isn't what this survey is priced for - it's built around a formal BS5837-format report a third party will read and act on
How a Commercial Tree Survey Runs From First Call to Final Report
- Initial enquiry and scoping: You tell us the site size, roughly how many trees are involved, and what's driving the request - an insurer's renewal date, a planning submission, a lender's condition - so we can confirm which survey tier and report format fits.
- Free site visit: A qualified assessor walks the site, identifying every tree within scope and recording species, condition and any visible defects.
- Category rating and root mapping: Each tree is given a BS5837 category, and where construction or extension work is planned nearby, its root protection area is calculated against the proposed layout.
- Report drafting: Findings are written up in a format matched to whoever's going to act on it - an insurer, a planning department, or your own records - with photographs and a management schedule where relevant.
- Delivery and, if needed, follow-up work: You receive the finished report to submit or file. If it recommends tree work, that's quoted separately and can be booked directly with the same team that carried out the assessment.
How Site Size and What the Report Has to Prove Set the Price
The single biggest factor in price isn't the number of trees on site - it's what the finished report has to demonstrate and to whom. A basic insurance-renewal check on a single building with a handful of trees nearby usually comes in at £350-£500, because the assessor is confirming category ratings and flagging anything an underwriter would query, not mapping root systems against a construction drawing. Where a planning application is involved, the fee moves up to £500-£750, since root protection area calculations have to be plotted against the actual proposed site layout rather than estimated by eye. Business parks, industrial estates and multi-building portfolios with extensive tree cover are quoted from £750 upward, because a full GPS-logged inventory across several buildings takes considerably longer than assessing the trees around one. If a site already holds a survey and just needs it kept current for a renewal date, the repeat visit under the annual monitoring programme is offered at a discounted rate agreed when you first sign up, rather than requoted from scratch each time. These bands are a starting point - a firm figure always follows a free visit rather than a phone quote.
Which Survey Tier Actually Fits Your Site
| Survey type | Best suited to | What you get | Price guide |
|---|---|---|---|
| Basic Insurance Survey | A single building or small site with a handful of trees near it | Individual tree assessment and BS5837 category rating in an insurance-ready report | £350-£500 |
| Full BS5837 Assessment | Sites with construction, extension or alteration work planned near trees | Root protection area mapping and a constraint plan to support a planning application | £500-£750 |
| Large Commercial Site Survey | Business parks, industrial estates or multi-building portfolios with extensive tree cover | Full tree inventory, GPS-mapped locations and a prioritised management schedule across the whole site | £750+ |
| Annual Monitoring Programme | Properties that already hold a survey and need it kept current for insurance renewal | A repeat inspection on a fixed schedule, so the report an insurer sees is never more than a year or two old | Discounted rate agreed at signup |
Writing the Report for Whoever Actually Has to Act on It
An insurer's underwriter and a council planning case officer read the same BS5837 category letter for different reasons, and a report that doesn't account for that ends up doing neither job properly. An underwriter wants to see, in a single line, whether a Category U tree sits close enough to a building, car park or access route to be flagged as a claims risk before a renewal is signed off. A planning officer wants the root protection area drawn against the actual site plan that's been submitted, not a generic buffer radius, because that's what decides whether a proposed extension or a new parking bay can go where the drawing shows it. We ask which of those two the report needs to satisfy before booking the site visit, rather than writing one generic document and hoping it covers both. Where a tree's condition is genuinely borderline - a mature ash with crown dieback, for example, which in this part of Scotland is now more often ash dieback disease than ordinary drought stress - the report says so directly instead of rounding the rating to whichever letter is easier to defend later. Site visits and quotes are free, so there's no cost in having an existing report checked over.
Commercial Survey Coverage Across the Wider Council Areas
Commercial site surveys extend across the same council areas as our wider service footprint, but what the assessment needs to focus on shifts with local planning practice as much as with distance from Glasgow. In West Dunbartonshire and Renfrewshire, where instructions often come from riverside industrial sites around Clydebank, Dumbarton, Renfrew and Greenock's docklands, root protection area mapping usually has to account for buried services and hard standing rather than open ground. Business premises in East Dunbartonshire's older estates - Bearsden, Milngavie, Kirkintilloch and Bishopbriggs - tend to carry mature specimen trees from Victorian-era planting, which is where a BS5837 category rating carries more weight than a simple hazard check. South Lanarkshire instructions around Rutherglen, Cambuslang, Blantyre and Bothwell, and East Renfrewshire sites around Giffnock, Clarkston, Newton Mearns and Barrhead, are more often retail parks and business units where the survey is driven by an insurer's renewal date rather than a planning condition. Further out, agricultural and rural business premises around Strathblane, Killearn, Balfron, Fintry, Kippen, Stirling and Bo'ness on the Firth of Forth fall within the same service area, usually for portfolio landlords managing sites across more than one council boundary at once.
Frequently Asked Questions
How is a commercial tree survey different from a residential one?
The inspection itself is the same process - condition, structure and BS5837 category rating for each tree - but a commercial report is usually written for a different audience. An insurer wants a category rating and a note on anything that could damage a structure or injure someone on site; a planning department wants root protection areas mapped against a proposed building or extension. We ask what the report needs to do before the site visit, so the write-up matches the audience it's going to.
What if I just want a general check on how my trees are doing, with no insurer or planning deadline behind it?
That's a different job, and a smaller one. This survey is priced and formatted around a report a third party has to read and act on - an insurer's underwriter, a mortgage valuer, a planning case officer - which is why it includes a formal BS5837 category rating and, where relevant, root protection area mapping against a site plan. If you just want an honest read on your trees' condition for your own records, say so when you get in touch and we'll scope something lighter rather than write a full planning-format report you don't need.
Do you cover multi-building sites or just single properties?
Both. A single building with a handful of nearby trees fits the basic insurance-survey tier. Business parks, industrial estates or portfolios with several buildings and extensive tree cover are surveyed as a full tree inventory with GPS-logged locations, since walking and mapping a large site takes longer than a single-building visit.
What does the BS5837 category rating actually mean?
It's a structured grading system - categories A, B, C and U - used to record a tree's quality and value alongside any hazard it presents, so a planning officer or insurer reading the report doesn't have to take our word for a tree's condition; the category comes from a recognised standard they already understand.
If the survey finds a tree that needs work, what happens next?
The report flags it and describes what's needed - a crown reduction, deadwood removal, or felling, for example - but that work is quoted and invoiced separately from the survey. You're not obliged to use us for the follow-up work, though if you do, it's carried out to BS3998 by the same team that assessed the tree.
Can the report be used for a Tree Preservation Order application?
Yes - we prepare and submit the paperwork alongside the survey findings. The council's own TPO consent fee isn't included in the survey cost; that's a statutory charge you pay directly to the local authority.
How do you handle a tree that's on a neighbouring property but overhangs our boundary?
We can note it in the report and describe what's visible from your side of the boundary, but we can't inspect it up close or recommend specific work on a tree we don't have the owner's permission to access. If it's relevant to your report, we'll say so and point you toward how to approach the neighbouring owner.
How often does a commercial site need re-surveying?
It depends on what the report is for. Insurers typically want a survey no more than a year or two old at renewal, which is why we offer an annual monitoring programme at a discounted repeat rate. A one-off planning survey doesn't need repeating unless the site changes or a new application is submitted.
What happens if a storm damages a tree between scheduled surveys?
That's treated as a new instruction rather than part of the existing survey, since the site condition has changed. Get in touch and we'll arrange a fresh site visit - if you're on the annual monitoring programme, this is often the point it earns its cost back, since it catches storm damage before the next scheduled check.
