Tree felling and stump height reduction

Removing a tree is a highly technical process that involves more than just a chainsaw. From navigating Tree Preservation Orders (TPOs) to safely grinding out the stump for future replanting, hiring an expert protects both your garden and your legal liability.

What Does the Work Involve?

• Site Assessment: Identifying the tree species, checking for signs of decay, and spotting hazards like overhead power lines or nearby glass structures.
• Legal Verification: Confirming if the tree is protected by a TPO or situated within a Conservation Area before any cutting begins.
• Sectional Felling: Dismantling the tree in small sections using ropes and lowering devices to prevent damage to the ground or buildings below.
• Straight Felling: Dropping the tree in one piece from the base, only if there is sufficient clear space and it is safe to do so.
• Stump Grinding: Using a mechanical grinder to chew the remaining stump into woodchips, typically to a depth of 150mm to 300mm below ground level.
• Waste Processing: Chipping smaller branches (brash) into mulch and cross-cutting larger timber into manageable logs for the homeowner or removal.

Typical Costs

Costs are primarily driven by the tree's size, its proximity to buildings, and ease of access for heavy machinery. Prices in London and the South East typically carry a 15-25% premium due to higher disposal costs and labour rates.

How Long Does It Take?

• Small Garden Tree: 2 to 4 hours for a two-person team to fell and clear.
• Medium Tree: 1 full working day, including stump grinding and site tidy.
• Large or Complex Tree: 2 to 4 days, especially if rigging is required to lower branches over a roof.
• Stump Grinding: 45 minutes to 2 hours per stump, depending on the wood density and size.

DIY or Professional?

Tree felling is one of the most dangerous domestic tasks and should never be a DIY job. Professional tree surgeons carry specific insurance and have the aerial rescue training required for high-risk work.

While you can prune small fruit trees yourself, anything requiring a ladder or a chainsaw must be handled by a qualified arborist. Attempting to fell a tree without professional rigging can lead to catastrophic property damage or fatal injury.

Choosing the Right Tradesperson

• Check Qualifications: Look for NPTC (City & Guilds) or LANTRA certificates for chainsaw use and aerial work.
• Insurance: Ensure they hold Public Liability insurance of at least £5 million to cover potential property damage.
• Written Quotes: Avoid "door-knockers"; always get a written quote that specifies if waste removal and stump grinding are included.
• Questions to ask:
  • Are you "Arboricultural Association Approved"?
  • Will you check for nesting birds and TPOs before starting?
  • How do you plan to protect my lawn/patio from heavy branches?
  • What is your plan for the "arisings" (waste material)?

UK Regulations

• Tree Preservation Orders (TPO): It is a criminal offence to cut down a tree protected by a TPO without council permission, with fines up to £20,000.
• Conservation Areas: You must give the Local Planning Authority six weeks' notice (a Section 211 notice) before felling any tree over a certain size.
• Wildlife and Countryside Act 1981: It is illegal to disturb nesting birds or bat roosts; work may need to be delayed between March and August.
• BS3998: This is the British Standard for tree work; your surgeon should confirm they work to these safety and quality guidelines.

Common Problems

• Underground Services: Stump grinders can easily sever shallow gas pipes, water mains, or fibre optic cables if they aren't located first.
• Poor Access: If the garden gate is too narrow for a wood chipper or stump grinder, labour costs will increase as everything must be moved by hand.
• Hidden Decay: A tree that looks solid may be hollow inside, making it unpredictable during felling and requiring specialist rigging.
• Boundary Disputes: Homeowners often mistakenly fell trees that actually belong to a neighbour or are situated on "no-man's land."

Frequently Asked Questions

When is the best time of year to fell a tree?

Winter (dormant season) is usually best as the lack of leaves makes the structure easier to see and there is no risk of disturbing nesting birds. However, dangerous or dead trees should be removed immediately regardless of the season.

Will the stump grow back after grinding?

Most species will not grow back once the main root flare has been ground down 150-200mm below the surface. Some species, like Willow or Poplar, may occasionally send up "suckers" from remaining deep roots, but these are easily managed.

Can I keep the wood for my log burner?

Yes, most surgeons are happy to "ring up" the main trunk into logs for you to keep. Be aware that fresh wood needs to be seasoned (dried) for at least 1-2 years before it is safe to burn.

Do I need my neighbour's permission?

If the trunk is entirely on your land, you do not need their permission to fell it. However, it is a matter of courtesy to inform them, as the work will be noisy and may involve branches overhanging their property.

What is the difference between a tree surgeon and an arborist?

The terms are often used interchangeably, but an arborist generally focuses on the health and science of the tree, while a tree surgeon performs the physical maintenance and removal. Most reputable UK firms employ staff who are both.
