Tree Insurance Survey Glasgow | NPTC PTI Reports

NPTC Professional Tree Inspector Reports to BS3998/BS5837 for Insurers, Lenders and Subsidence Claims

If your insurer or mortgage lender has asked for a tree insurance survey in Glasgow, it usually means a tree sits close enough to a building, drain or boundary wall that an underwriter wants written proof of the risk before they will renew a policy, settle a claim or release funds on a purchase. Clay-heavy ground across the Clyde basin makes this a live issue for a lot of Glasgow properties, and once a solicitor or claims handler has set a deadline, the clock is already running. CNJ Tree Services carries out these inspections directly rather than farming the fieldwork out to a subcontractor: the same person who measures the tree against your foundations also handles any follow-on pruning, reduction or removal work the report recommends, and the survey can be widened into a fuller arborist inspection if your policy or lender wants more than a single-tree opinion.

Worth knowing before you book: an insurance survey is a written risk opinion aimed at an underwriter or lender, not the same document as a planning-grade BS5837 survey needed for an extension or new build near protected trees. The two get confused often, and paying for the wrong one wastes both time and money. A short conversation up front, describing what your insurer or solicitor has actually asked for, sorts out which report you need.

At a Glance

• NPTC Professional Tree Inspector qualified, not a generalist writing outside their training
• Reports built to BS3998 and BS5837 methodology, the standards insurers and planners recognise
• £5 million public liability cover backing every visit and every report

What Insurers, Lenders and Solicitors Actually Require in This Report

• A tree-by-tree schedule of every tree within influencing distance of the insured building, recording species, height, crown spread and estimated root spread
• Measured distances from each tree to foundations, drains, boundary walls and any other structure your insurer has flagged
• A note on soil type and drainage relevant to subsidence risk, including where clay content in the local ground raises or lowers likely root-related movement
• A visual tree assessment of each specimen for structural defects: deadwood, cavities, included bark, historic storm damage, previous poor pruning cuts
• A photographic record cross-referenced to the tree schedule, so the insurer can see exactly what was inspected
• A written risk opinion for each tree with a recommended action (leave and monitor, prune, reduce, or remove) and an approximate cost bracket for that work
• A signed PDF report formatted for submission to an insurer, lender or solicitor, referencing BS3998 and BS5837 where relevant

Not Included / Costed Separately

• A full BS5837 planning survey with a constraints plan and root protection area drawings for a planning application - this is a different, longer piece of work, quoted separately
• Root identification by excavation or root mapping - the report will recommend this where genuinely needed, but it is not part of the standard visual survey and is priced separately if instructed
• Soil sampling or laboratory analysis for a definitive subsidence diagnosis - where a case needs that level of proof, referral to a chartered structural engineer or arboricultural consultant is the honest next step, not something covered by this survey
• A full structural inspection of a neighbour's tree without access arranged - a visual opinion can be given from your side of the boundary, but entering next door needs their permission first
• The recommended tree work itself - the survey is the risk opinion, not the pruning or felling it recommends, though both can usually be quoted at the same visit
• Formal expert witness attendance at a tribunal or court hearing - available on request, priced and scoped individually rather than bundled into a standard survey fee

From Your First Call to a Report in Your Insurer’s Inbox

1. Initial call: You describe the situation - a lender's request, a renewal query, a subsidence worry, a storm-damaged tree - and give a rough idea of property size and tree numbers, so a realistic price band and a survey date can be given over the phone rather than left vague.
2. Site visit booked: A visit is arranged directly with you, not routed through a call centre or a subcontracted network, so the person who turns up on the day is the person who quoted the job.
3. On-site inspection: The inspector measures each relevant tree against the building, checks the ground and drainage, and carries out a visual tree assessment for structural defects, photographing as they go rather than relying on memory once back at the office.
4. Report drafted: Findings are written up against BS3998 and, where the case calls for it, BS5837 methodology, with a plain-English risk opinion sitting alongside the technical detail an underwriter needs to see.
5. Report delivered: The finished PDF goes to you, or direct to your insurer, lender or solicitor if you'd rather it went straight to them, with the inspector's name and qualification on the cover page.
6. Follow-up work, if recommended: Where the report recommends pruning, reduction or removal, the same crew can carry that out using CNJ's own cherry picker, excavators and chippers, rather than you having to find a second contractor and start again from scratch.

Typical Fees for an Insurance-Standard Survey

Across the UK, a single-tree targeted survey written for insurance purposes generally costs somewhere in the region of £300 to £420, and a subsidence-specific report - the kind an insurer asks for once root-related ground movement is suspected - typically starts from around £400 to £500 and rises from there depending on how many trees and how much investigation the case needs. Where you land in that range depends on the number of trees on and around the property, how many buildings or boundaries need distance checks, whether the soil and drainage picture needs a closer look, and how quickly the report is needed. A tight completion date or an out-of-hours visit tends to push the fee toward the top of the bracket rather than the bottom. None of this replaces an actual quote: a fair price for your specific property needs a site visit, because a single mature oak six metres from a bay window is a different job to five self-seeded sycamores against a garden wall, even if both look like “one survey” on paper.

How This Compares to a Generic Tree Report

A Single Named Inspector, Not a Subcontracted Signature

An insurance survey lives or dies on whether the person signing it actually holds the qualification an underwriter’s technical team is trained to look for. Every CNJ report carries one name throughout - Callum Jackson’s NPTC Professional Tree Inspector certification, gained in 2023 - rather than being drafted by whoever happens to be free that week and checked over by someone else afterwards. The inspector who walks the garden and measures each tree against the foundations is the same person who writes the risk opinion and signs the cover page, so there’s no handoff between a fieldworker and a separate report-writer where detail gets softened or lost in translation, and no work farmed out to a subcontracted surveyor whose name never appears on the document at all. That single point of accountability matters because the judgement calls in a report like this - telling a cosmetic bark wound from a structural crack, or a decades-old lean from one that started last winter - come from someone who has actually stood under the tree in question, not from a checklist completed at arm’s length. Every report ties back to BS3998 for the tree work itself and BS5837 where planning-grade detail applies, backed by CNJ’s own £5 million public liability cover, so whoever reads it - a claims handler, a lender’s surveyor, a solicitor working to a completion date - is looking at a document built to the standard their own guidelines already expect, signed by the one person who can be asked to explain any line in it.

The Ground Conditions Behind These Surveys

For a subsidence-specific survey, the ground itself often matters more than which side of the city the tree happens to sit on: the clay that runs either side of the Clyde and Kelvin river valleys shrinks and swells with moisture in a way that can genuinely shift foundations, whereas the sandier, rockier ground out toward the Campsies or the Kilpatrick Hills rarely raises the same subsidence question - though gardens up near the Cathkin Braes or the Kilpatrick ridge tend to bring a wind-risk assessment into the report instead. A lot of the trees generating these surveys are older than the buildings beside them: Glasgow’s West End and Southside carry mature Victorian-era gardens, and where a tree flagged for reduction or removal sits inside a Conservation Area, the report has to note that Glasgow City, East Dunbartonshire or East Renfrewshire planning consent may be needed alongside the insurer’s sign-off - a complication a generic report can easily miss. Domestic surveys run within a ten-mile radius of CNJ’s Newton Place base in Glasgow’s West End, covering the city itself plus the surrounding towns: Clydebank and Paisley to the west, Bearsden and Bishopbriggs to the north, Giffnock and Newton Mearns to the south, Rutherglen and Cambuslang to the southeast. Storm-related insurance assessments are handled on a wider footing, with 24-hour emergency response out to 50 miles and an average arrival under two hours, and larger commercial or estate surveys are carried out across Scotland rather than being tied to the domestic radius.

Frequently Asked Questions

Book Before Your Renewal Date or Completion Deadline Arrives

A tree risk report is far cheaper to commission now than a policy exclusion or a rejected subsidence claim is to argue with later, and insurers rarely move quickly once a deadline is already close. Getting a survey booked while there’s still time to act on its recommendations - a prune, a reduction, or simply a documented decision to monitor - puts you in a stronger position with whoever is asking for it, whether that’s an underwriter, a lender or a solicitor working to a completion date.
