What is crown reduction?
Crown reduction is the process of shortening branches back to a suitable growth point so the overall height and spread of the tree is reduced by a set percentage — typically 15–30%. Done correctly under British Standard BS3998, the tree keeps its natural shape and continues to grow healthily.
It is not the same as topping — a discredited practice that leaves stubs, promotes weak regrowth and can kill mature trees.
When does a tree need reducing?
Common reasons for crown reduction in Chichester include trees blocking light, overhanging buildings or driveways, becoming top-heavy after years of unmanaged growth, or sitting on the edge of a TPO or conservation area where felling isn't permitted.
Reduction also reduces wind sail on exposed trees, which is important around the Downs and the harbour.
Reducing height and spread safely
A good reduction is planned before a saw is picked up. We assess the tree from the ground, decide on target growth points, and climb using proper rope systems so every cut is placed correctly. Timber is lowered in controlled sections, especially around driveways and glazed extensions.
Protecting the shape and health of the tree
A well-executed crown reduction should be almost invisible to someone who didn't know the tree before — smaller, tidier, in proportion, but still natural in shape. Overzealous reductions cause vigorous water-shoot regrowth and long-term weakness.
This is why qualifications and understanding of the species matter as much as the saw work itself.
Crown reduction in Chichester and surrounding areas
We carry out crown reductions across Chichester, Fishbourne, Bosham, Lavant, Boxgrove and the Goodwood estate villages. Many of these locations are in conservation areas or hold TPO-protected trees, so we handle the council notifications on your behalf.
Why use a qualified arborist?
Crown reduction is one of the easiest jobs to get wrong. Choosing a qualified arborist — with the right training, insurance and understanding of BS3998 — is the difference between a tree that thrives for another 40 years and one that has to be felled in five.

Frequently Asked Questions
How much does a crown reduction cost in Chichester?
Prices depend on tree size and access but typically start from around £400 for a small domestic tree and rise with height and complexity.
How much can you reduce a tree by?
Under BS3998, reductions of up to around 30% of the live crown are normally the sensible maximum. More than that risks stress and poor regrowth.
When is the best time of year for crown reduction?
Most broadleaved trees are best reduced in late autumn to early spring. Some species — cherry and plum — are pruned in summer to reduce disease risk.
Do I need council permission in Chichester?
Very often yes — Chichester has extensive conservation area coverage and many TPOs. We check and handle the paperwork.
Will the tree grow back the same shape?
A properly reduced tree keeps its natural form and regrows gently. Poorly topped trees regrow with dense, weak shoots and lose their natural shape.
