Commercial Tree Work in Winter: What Property and FM Teams Should Book Now

Written By Wez - 21/10/2026

Commercial tree problems tend to announce themselves the morning after a storm: a limb across the car park, a tree leaning on a boundary fence, a tenant asking who is responsible. Almost all of them are cheaper, safer and easier to deal with in October than in January. Autumn and winter is the natural window for commercial tree surgery, surveys and planned works, and the sites that use it well have far quieter winters.

This guide is for facilities managers, property and estate managers, block managers, schools, healthcare estates and anyone else responsible for trees on a commercial site. It covers why the season matters, what to book, the paperwork that has to come first, and a short pre-winter checklist.

Why autumn and winter is the window for commercial tree work

It sits outside bird nesting season. The main season runs 1 March to 31 August, and disturbing an active nest is an offence under the Wildlife and Countryside Act 1981. Major works programmed for autumn and winter avoid nest checks stalling the job halfway through. (More in our guide to bird nesting season in the UK.)
Leaf-off is the best time to see a tree properly. With the canopy gone, deadwood, weak unions, cracks, cavities and previous poor pruning are far easier to spot. Many decay fungi also fruit in autumn, which is when the warning signs show.
Storm season is when weak trees fail. Wind, saturated ground and heavy rain do their damage between October and March. A defective limb removed in November is a planned job. The same limb on a car in February is an insurance claim.
Budgets line up. Many organisations, including most of the public sector, close their financial year on 31 March. Programming works now means spend can be committed, phased and delivered before year end rather than rushed in the last fortnight.
Sites are often quieter. Lower footfall in the grounds, shorter trading hours and school holidays all make exclusion zones easier to run on live sites.

Winter is the other half of the picture. At midday in December the sun is only about 15 degrees up, and that low light is exactly what makes a south-facing garden and the rooms behind it worth having. Anything that blocks it all year round costs you in winter. That is the argument for deciduous trees and climbers, which shade you in summer and drop their leaves just as you want the light back.

Start with a tree survey, not a list of jobs

Under the Occupiers’ Liability Acts 1957 and 1984, whoever controls the land owes a duty of care to everyone its trees could affect. There is no fixed statutory inspection interval, but a competent, documented inspection regime is the accepted evidence that reasonable care was taken. “We never looked” is not a defence.

A tree condition survey records what you have, what condition it is in, what risk it presents to the people and property beneath it, and what work it needs, with priorities and re-inspection intervals. For most managed sites that means a full survey every one to three years, with high-use areas such as car parks, entrances, play areas and footpaths at the shorter end, plus walkover checks in between and after major storms.

If you are planning development rather than managing existing trees, you need a different document: see what a BS5837 tree survey is and when you need one.

What a winter tree works programme usually includes

Every site is different, but most commercial winter programmes are built from the same core tasks:

Crown lifting over car parks, roads, footpaths and signage to restore clearance. Commonly around 5.2m over carriageways and 2.5m over footways, though your highway authority's standard is the one that counts.
Deadwood removal from trees over areas where people park, walk or gather.
Crown reductions and thinning to reduce wind loading on trees that are worth keeping.
Sectional dismantling and removals of dead, dying or structurally unsound trees, especially over buildings, infrastructure and live operational areas.
Ash dieback works, which remain one of the biggest drivers of commercial tree removals. Our guide covers the signs of ash dieback.
Stump grinding after removals, so the area can be resurfaced, replanted or mown. See commercial stump grinding.
Boundary and vegetation management: encroaching growth, self-set trees, overgrown hedgerows and closing sightlines at entrances.
Replanting, which is best done over the dormant season while bare-root stock is available.

Delivered as a planned programme, these works cost less per tree than reactive callouts, spread spend predictably across financial years, and shrink the emergency budget line because failing trees get caught before they fail.

The paperwork that has to come first

This is where winter programmes most often slip. If any of your trees are protected, the consents need to be in hand before the window closes at the end of February.

Tree Preservation Orders. Work on a TPO tree without consent from the local planning authority is a criminal offence, with fines applied per tree. Applications can take up to eight weeks to decide.
Conservation areas. Most work to trees in a conservation area needs six weeks' written notice to the authority before it starts, even where there is no TPO. Large parts of Cheltenham and the Cotswold towns sit within conservation areas.
Felling licences. Felling beyond small volumes can need a licence from the Forestry Commission, an obligation often missed on estates and larger sites.
Bats. Bats and their roosts are protected all year, and some hibernate in trees over winter. Trees with roost potential are assessed before work, whatever the season.

If you are not sure whether a tree is protected, our guide to TPOs and tree work permission explains how to check. In short: if consent is needed and you have not applied by early December, it is unlikely to land in time for this winter.

Have a storm plan before you need one

When weather takes trees down across a site or portfolio, the order of response matters: access and safety first, documentation for insurers second, tidy-up third. The organisations that cope best are the ones that agreed this in advance.

Agreed callout terms with a tree contractor, written into the contract, so nobody is ringing round at 7am.
One number whichever site has the problem.
Documented make-safe works, photographed and recorded, so insurance claims do not stall.
Post-storm walkovers of high-risk areas once the weather clears, recorded as part of your inspection regime.

A pre-winter checklist for facilities and property managers

Find your last tree survey. If it is more than three years old, covers only part of the site, or does not exist, book one now.
Check the outstanding works list. Any high-priority recommendations still open are your first winter jobs.
Walk the high-risk zones: car parks, entrances, footpaths, play areas, and anything near buildings or roads. Look for deadwood, hanging limbs, fungal brackets, leaning trees and lifting roots. Our guide to signs a tree is dangerous covers what to look for.
Check protection status for any tree you expect to work on, and get TPO applications and conservation area notices submitted.
Confirm your storm arrangements: who you call, what the callout terms are, and who on your side signs off emergency works.
Book the works for November to February, phased around your operational calendar and budget.
File the records. Survey, consents, risk assessments and completion records together, so the duty of care is evidenced if an insurer, auditor or solicitor ever asks.

Survey to works, one contractor

Most survey providers hand you a report and a problem. Silver Tree Services hands you a report and a priced works schedule. We are a 30-plus person arboricultural contractor based in Shurdington, Cheltenham, with ISO 9001 and ISO 14001 certification, ARB Approved Contractor status and SMAS SSIP accreditation. Our NPTC-certificated crews work to BS3998:2010, with RAMS produced for every site and DBS-checked operatives available for sensitive settings.

Survey findings move straight into a programmed works schedule, TPO and conservation area paperwork is handled as part of the job, and alongside the written report you get a live interactive version that updates as work on each surveyed tree is completed. It is how we manage trees for clients including the NHS, Gloucestershire Police, Stroud District Council and Savills, across Gloucestershire, surrounding counties and nationwide for larger contracts.

Want your trees sorted before the storms arrive? See commercial arboriculture, or call 01242 472560 and tell us about the site. We will scope a survey, build a winter programme and give you numbers your budget holder can plan around.

Frequently Asked Questions About Commercial Tree Work

Frequently asked.

Is winter a good time for commercial tree surgery?

Yes. Autumn and winter falls outside the main bird nesting season (1 March to 31 August), trees are easier to assess with the leaves off, and removing defective limbs before storm season reduces the risk of failures. Most trees also tolerate pruning well while dormant. The main constraints are consents for protected trees and year-round protection for bats, both of which should be checked before work is booked.

Do I need a tree survey before commercial tree work?

Not for every job, but for any site with a meaningful number of trees and public access, a survey should come first. It identifies what actually needs doing and in what order, gives you a defensible record of reasonable care under the Occupiers’ Liability Acts, and turns tree spend into a planned programme rather than a series of reactive callouts.

How often should trees on a commercial site be inspected?

There is no fixed legal interval; the standard is what is reasonable for the site. In practice that usually means a full condition survey every one to three years, with high-use areas inspected more often, interim walkovers, and checks after significant storms. The report should set a recommended re-inspection interval for each tree or zone.

Who is responsible if a tree on a commercial site falls and causes damage?

Generally the party in control of the land, which may be the owner, the occupier or a management company, depending on the arrangement. Liability turns on whether the harm was foreseeable and whether reasonable care was taken, which is why a documented, competent inspection regime matters so much.

Can tree work go ahead in winter if bats might be present?

Sometimes, but it needs care. Bats and their roosts are protected year-round, and some species hibernate in tree cavities over winter. Trees with roost potential should be assessed before any work, and if a roost is found the works may need to be redesigned, rescheduled or carried out under ecological advice.
