Reports that stand up to scrutiny

If your site has trees on or near it, your local planning authority will almost certainly ask for a tree survey undertaken to British Standard BS5837:2012. We carry out comprehensive assessments covering tree plotting, measurement and categorisation from high-value to unsuitable for retention — including constraint plans, impact assessments, and protection documentation for retained trees during construction.

Mortgage lenders sometimes ask for an arboricultural report when trees stand close to a property, particularly where subsidence is a concern. Our surveys are carried out by qualified, experienced arborists — the same people who work with trees every day, not just behind a desk — delivering practical, compliant reports with a rapid local turnaround across the North West.

FAQs

Tree survey questions

What is a BS5837 tree survey?
It's the British Standard covering trees in relation to design, demolition and construction — recording, measuring and categorising every relevant tree so a planning authority can assess a development's impact on them.
Do I need a survey for a mortgage application?
Sometimes — lenders may ask for one where trees stand close to a property, particularly if subsidence is a concern. We can turn these around quickly to keep your application on track.
How long does a survey take?
A typical residential survey can be carried out in a single site visit, with the report following shortly after. Larger commercial or development sites take longer depending on the number of trees involved.
Can you help if trees need protecting during construction?
Yes — we prepare Arboricultural Method Statements and tree protection plans, and can supervise retained trees on site throughout the build.
