Why Great Oaks

What you get here that a survey-only firm cannot offer

1

One firm, survey to sign-off

We write the report and, as an ARB Approved Contractor, we can carry out the works it recommends. No second procurement problem. Survey and works are always quoted separately, and you are never obliged to use us for either.

2

The price we quote is the price you pay

All-in quotes with expenses included. No follow-on surprises after the survey day, and any further work is agreed before it is priced.

3

Local, so genuinely fast

We are based in Preston, not a national call centre. Most quotes go back within one working day and survey visits are booked within days across Lancashire and the North West.

4

Credentials that carry weight

ARB Approved Contractor, Constructionline Gold and Fusion21 approved, with £5m public liability and £10m employers liability insurance. The paperwork planners and procurement teams ask for is already in place.

Not sure which survey you need?

One question. We will name the survey, tell you what you receive, and how quickly.

  • Tree constraints plan your architect can overlay on the site drawings
  • Impact assessment, method statement and protection plan available as the application progresses

  • Tree identification and condition
  • Risk and subsidence commentary a lender will accept
  • Clear recommendations, plainly written

You need a managed tree survey programme

Duty of careEstates, schools, councils

If you are responsible for land with trees, you carry a legal duty of care. A recorded survey cycle is how that duty is evidenced. We survey the stock, record it, and put re-inspection dates in the diary so nothing is missed.

  • Full tree stock survey and records
  • Prioritised works programme
  • Recorded re-inspection cycle for your compliance file
Get a free scope check

You need a root investigation

Insurance gradeTree radar available

Where roots are suspected of affecting structures or drains, we investigate below ground and report what is actually there, with findings insurers and engineers can rely on.

  • Root investigation, including tree radar where appropriate
  • Clear findings on species, extent and involvement
  • Report written for insurers, engineers and loss adjusters
Get a free scope check

You need TPO and conservation area advice

Protected treesApplications handled

Works to protected trees need consent, and a well-argued application with the right evidence is the difference between yes and no. We advise on what is realistic and prepare the supporting report.

  • Advice on what consent is needed and what will be granted
  • Supporting survey and report for the application
  • If consent is granted, we can carry out the works as an ARB Approved Contractor

Then, if works are needed

The part a survey-only firm cannot do

Most reports end with recommended works. We are an ARB Approved Contractor, so the same firm that wrote your report can carry them out, priced separately, with no obligation. You are always free to take the report to any contractor you like.

Questions

Frequently asked

Do I always need a full BS5837 package for planning?+

No. Councils ask for different things at different stages, and many applications only need the survey and constraints plan at first. Our free scope check confirms what your council actually requires, so you never buy more than the application needs.

How long does a BS5837 tree survey take?+

The site visit is usually a single day for most sites. Your report follows days after the visit, not weeks. Larger or more complex sites are agreed up front when we scope the work.

How long is a tree survey valid for?+

For planning purposes most authorities expect the survey to be recent, and in practice up to around two years old depending on the site and season. If yours is older, we can often update an existing survey rather than starting from scratch.

How much does a tree survey cost?+

It depends on the size of the site, the number of trees and the drawings required, which is why the scope check comes first and is free. What we promise: the quote is all-in with expenses included, and the price we quote is the price you pay.

Can you attend design meetings or meet on site?+

Yes. For development work we can join design team meetings, meet your architect on site and liaise with the council's tree officer directly.

Do you cover my area?+

We are based in Preston and work across Lancashire and the North West. Applying for planning in the city itself? See our dedicated BS5837 tree surveys in Preston page. Anywhere else in the county, see tree surveys in Lancashire. If you are further afield, ask; for larger commissions we travel.

Can the same firm do the works the report recommends?+

Only if you choose that, and the report never depends on it. The survey is priced and delivered on its own, its recommendations are what the tree actually needs, and where no work is needed the report says so. You are free to take our report to any contractor. If you would like us to quote for recommended works, we do so separately as an ARB Approved Contractor, with no obligation either way.

Is your work insured?+

Yes. We carry £5m public liability and £10m employers liability insurance, and we are ARB Approved Contractor AC2637, Constructionline Gold and Fusion21 approved.
