A tree surgeon - also known as an arborist - is a qualified practitioner who carries out practical tree work using chainsaws, aerial rigging and specialist equipment. They differ from an arboriculturist, who provides consultancy and written reports. Tree surgeons must hold NPTC/City and Guilds chainsaw certificates as a legal minimum, and Arboricultural Association Approved Contractor status is the standard quality benchmark for domestic and commercial work.
What they do
- Crown reduction, thinning and lifting
- Dead-wooding and hazard branch removal
- Pollarding and coppicing
- Tree felling - sectional dismantling and straight felling
- Stump grinding
- Hedge reduction and reshaping
- Emergency work after storm damage
- Tree work specified by an arboricultural consultant's report
When you need one
Any practical tree work - whether routine maintenance or emergency removal - should be carried out by a qualified tree surgeon with appropriate insurance.
Typical costs (UK, 2025)
| Job type | Typical cost |
|---|---|
| Small tree pruning (ground-level work) | £150 - £350 |
| Medium tree crown reduction | £350 - £800 |
| Large tree felling | £500 - £2,000+ |
| Stump grinding | £100 - £400 |
| Emergency call-out (storm damage) | £300 - £1,000+ |
| Hedge reduction (per hour) | £60 - £90 / hr |
Access is a major cost driver - trees in restricted locations or close to buildings cost more to remove. Always confirm disposal of timber and woodchip is included in the quote.
Qualifications to look for
CS30, CS38 and CS31 (aerial) are mandatory competency certificates for safe chainsaw use. Any tree surgeon working with chainsaws must hold the relevant certificates. Always ask to see copies before work starts.
The standard quality mark for tree surgery businesses. Approved Contractors are assessed for qualifications, insurance and working practices. Find an AA Approved Contractor at trees.org.uk.
How to find a reputable tree surgeon
Frequently asked questions
What qualifications does a tree surgeon need?
As a minimum: NPTC/City and Guilds CS30 (chainsaw maintenance and crosscutting) and CS38 (felling small trees). For aerial work: CS31 (use of a chainsaw from a rope and harness). Arboricultural Association membership and Public Liability Insurance are strongly recommended - always check both before appointing.
Can a tree surgeon remove a tree with a TPO?
Not without consent from the local planning authority. A TPO tree can only be removed if it is dead, dying or dangerous, or if formal consent has been granted by the council. An AA-accredited tree surgeon or arboricultural consultant should advise on whether the tree qualifies for exemption and manage the application if consent is needed.
How much does tree removal cost?
Small trees under 5m typically cost £200-400 to remove. Medium trees (5-10m) £400-900. Large trees over 15m £1,000-3,000+. Costs vary significantly based on access, species, proximity to buildings and what happens to the timber and arisings.
