Site Clearance and Tree Removal Before Building Work: A Guide for Developers in Cambridgeshire and Hertfordshire

Site clearance tree removal means felling the trees, grinding out the stumps and clearing the scrub and vegetation on a plot so that building work can start safely. On most developments it should be done before groundworks begin, after you have checked any tree surveys, planning conditions and protections, and ideally outside the main bird nesting season.

For builders, developers and estate agents across St Neots, Cambridgeshire and Hertfordshire, getting this stage right keeps a project on programme. Getting it wrong can mean delays, fines or a stalled site. Here is what you need to know.

What does site clearance tree removal involve?

Every site is different, but a typical clearance job covers four main tasks.

Felling and dismantling trees

Trees are either felled in one piece where there is room, or taken down in sections where space is tight or there are buildings, roads or power lines nearby. Our tree felling and removal service starts with an assessment of each tree’s condition, location and risks, then a plan for bringing it down safely.

Stump grinding

Once the trees are down, the stumps need dealing with. Stump grinding uses a specialised machine to grind each stump down to below ground level, leaving the area level and ready for the next stage of work.

Vegetation and scrub clearance

Overgrown plots often carry brambles, saplings, self-seeded scrub and old hedging. Clearing this opens the site up for surveyors, engineers and plant, and shows what you are really working with.

Dealing with the arisings

Cut timber and brash have to go somewhere. Wood can be chipped for mulch, processed into logs or taken for recycling at designated facilities, so the site is left clear rather than covered in debris.

When should trees be cleared from a development site?

The order matters. Clearance should come after the tree survey and any planning conditions have been checked, and before groundworks start. Clearing too early, before permissions are confirmed, is one of the most common and expensive mistakes on smaller developments.

Timing in the year matters too. Autumn and winter are the most practical seasons for large clearance jobs. The main bird nesting season runs from roughly March to August, and it is an offence to damage or destroy an active nest. Nests are protected whatever the month, so any site should be checked before work starts, but clearing in the colder months greatly reduces the risk of holding up your programme.

Do you need permission to remove trees on a building site?

Often, yes. Before any tree comes down, check the following:

• Tree Preservation Orders (TPOs): Protected trees need consent from the local planning authority before work.
• Conservation areas: You must give the council six weeks’ notice before carrying out most work on trees in a conservation area.
• Planning conditions: Your planning permission may say which trees must be kept, how they must be protected and what can be removed.
• Felling licences: Large volumes of timber may need a felling licence from the Forestry Commission, although there are exemptions, including some work covered by full planning permission.

We help clients work through the permit process and make sure the right paperwork is in place before any removal begins.

Should stumps be ground or fully removed?

For most cleared plots, grinding is the quickest and least disruptive option. It takes the stump below ground level and leaves the roots to decay naturally over time. Where foundations, drainage runs or services are planned close to a stump, your structural engineer may ask for more, so raise this at the quote stage and we can plan the right approach.

What should builders and developers look for in a tree contractor?

When you are choosing a contractor for site clearance, ask:

• Are they fully insured? This is non-negotiable on any commercial site.
• Do they assess before they cut? A proper look at each tree, the access and nearby structures should come first.
• Can they handle bigger removals? Large trees near boundaries and buildings need dismantling skills, not just a chainsaw.
• Will they leave the site clean? Clearance is only finished when the debris has gone.
• Do they communicate well? Neighbours, site managers and agents all need to know what is happening and when.

CG Trees & Landscaping works on residential, commercial and municipal properties, and our customers regularly mention clear communication and tidy sites in their reviews.

Frequently asked questions

How long does site clearance tree removal take?

It depends on the number and size of the trees, access to the site and how much vegetation needs clearing. We assess the site first so we can give you a realistic timescale before work starts.

Can trees be cleared from a site during the nesting season?

Work can go ahead in spring and summer, but the site must be checked for active nests first because they are protected by law. Clearing in autumn and winter avoids most of this risk.

What happens to the wood after a site is cleared?

Timber and brash can be chipped for mulch, processed into logs or taken for recycling at designated facilities. Either way, the site is left clear and tidy.
