Crown Lifting in Cambridgeshire: A Guide for Councils, Highways Teams and Property Managers

Crown lifting is the removal of a tree’s lowest branches to create clearance beneath the canopy, and in Cambridgeshire it is most often used to keep roads, footpaths, sightlines and street lights clear. For councils, highways teams and managing agents, it is usually the quickest way to deal with low branches without losing the tree.

This guide explains when crown lifting is the right choice, who is responsible for overhanging branches, and what good crown lifting work looks like across St Neots, Huntingdon and the wider county.

What is crown lifting and why is it used?

Crown lifting is a pruning technique that removes the lower branches of a tree to increase the space beneath it. The rest of the crown stays in place, so the tree keeps its natural shape and continues to provide shade, screening and wildlife value.

It is commonly used to:

• Keep roads and footways clear for vehicles and pedestrians
• Restore visibility at junctions, bends and entrances
• Stop branches blocking street lights, signs and CCTV
• Give clearance over car parks, access roads and buildings
• Let more light and air reach the ground below

Our crown lifting service covers residential and commercial settings, from single roadside trees to whole lines of trees along an estate boundary.

How high should a crown be lifted over a road or footpath?

There is no single height that suits every site. Highway authorities set their own minimum clearances, and the figure over a carriageway is higher than over a footway because buses, lorries and other tall vehicles need more room than pedestrians. Always check the standard your local highway authority applies before specifying the work.

Good practice also limits how much is taken off at once. A common rule of thumb is to keep at least two thirds of the tree’s height as live crown. Where a tree needs lifting by a lot, it is often better to lift it in stages over several years rather than all in one go. BS 3998, the British Standard for tree work, gives recommendations on pruning cuts and timing that a good contractor will follow.

Who is responsible for branches overhanging a road?

The owner of the land where the tree grows is normally responsible for keeping its branches clear of the highway. Under section 154 of the Highways Act 1980, a highway authority can serve notice requiring an owner to cut back trees or vegetation that obstruct the road or footway, or block the view of drivers or the light from street lamps.

That means estates, businesses, schools, housing providers and private landowners all have a duty to keep roadside trees in check, not just the council.

When is the best time of year for crown lifting?

Crown lifting can be carried out for most of the year. Winter is a practical time for many trees because the leaves are off and the branch structure is easy to see. A few species, such as birch and maple, bleed sap heavily if pruned in late winter or early spring, so their timing needs more thought.

During spring and summer, trees should be checked for nesting birds before work starts, as active nests are protected by law.

Crown lifting or tree felling: which is right?

If a tree is healthy and the only problem is low branches, crown lifting is almost always the better option. It keeps the tree and deals with the issue quickly.

Felling becomes the right call when a tree is diseased, badly damaged, leaning, hollow or too close to structures or power lines to manage safely. In those cases our tree felling and removal team can take the tree down in sections and clear the site.

What does the crown lifting process look like?

Every job starts with an assessment of the tree to identify which branches need removing. Our arborists then plan the pruning so the canopy stays balanced and the tree is not put under undue stress.

On roadside and public sites, the work also needs planning around traffic and people. We discuss access and any traffic management requirements at the quote stage so the work runs safely. Lower branches are removed with specialised tools, surrounding structures and vehicles are protected, and the site is cleared of debris when we finish.

Frequently asked questions

Does crown lifting harm the tree?

When it is done properly and not too much is removed at once, crown lifting keeps the tree healthy and keeps its natural shape. Problems come from removing too many large branches in one go.

Do I need permission for crown lifting?

If the tree is covered by a Tree Preservation Order you need consent from the local planning authority, and in a conservation area you must give the council six weeks’ notice. We can help you work through this before any work starts.

Can crown lifting be done on several trees at once?

Yes. Lines of roadside trees, estate boundaries and car park trees are often lifted in one visit, which keeps disruption to a minimum.
