What is a tree survey? When is a tree report needed?

Buying property

When you move into a new property your insurance company or mortgage lender may require a tree report.

Many of the major lenders in the UK require a report from a tree surveyor to state that there is no reason, from an arboricultural perspective, that a mortgage cannot be provided on a property. Mortgage providers need to be assured that there is no risk of tree related damage.

Property extension

Tree surveys may also be  required if you are applying for  planning permissions for an extension or renovations and there are trees nearby. In this case a tree survey report would  accompany your submitted plans to the local authority.

In either case, you will require a tree report that conforms to the official BS 5837 standard.

Tree condition report

A tree condition report is a simpler survey. This may be required if you have trees that could affect persons or property in the event of a failure. This could apply to a domestic property, commercial land or an area of public use.


A full tree survey will collect a range of  information such as:

  • Species of the tree (scientific name).
  • Physical measurements eg height and diameter
  • Age
  • Overall health
  • Life expectancy
  • Possible hazards
  • Management recommendations
Brown leaf


BS5837 is the British Standard for Trees in relation to design, demolition and construction – Recommendations. The latest version was published in 2012 and applies to all trees that could be affected during the design, demolition or construction phase of a development. It is mandatory to comply with BS5387 when considering any development project in the vicinity of trees, whether or not planning permission is required.

Can't speak highly enough of this team. Professional, experienced, polite etc etc. 4th time they've been to me ( I don't live in a forest , just got lots of large unruly trees). Ryan and Calum did an amazing job on them. No complaints as they ploughed through all my requests in the pouring rain. Mustn't forget Kate in the office and Billy who leads the team. All of them are fantastic. If you need any tree work Evoke are the only ones to call. Thanks guys . Photo before and after on the front hedge

I've used Evoke Tree Services for crown reduction to my large oak tree, hedge trimming, ivy removal and now log supplies. I will continue to use them as their customer service and attention to detail is second to none. Billy and the team are brilliant and I would highly recommend them to anyone seeking a service they provide. Thanks Evoke!

Second time using Yvoke and can't be more pleased. The business is knowledgeable and reputable. The last couple of days the guys have been hard at work, they are professional, polite and so hard-working and left my garden super clean. They worked so hard. Could not be more pleased - thanks all and see you next time.

We were delighted by the work Evoke did on our hedge. This was a significant pruning but was done with care and commonsense. It resulted in a job that was superb - and looked better than anticipated. Their professionalism was appreciated; we can highly recommend the company. Jim

We have used Evoke for our tree work for several years. As always, a very well-done job from start to finish, including the initial visit and obtaining the appropriate permissions from the WHC. All the trees were pruned as requested to a very good shape and the site was cleared of all rubbish.

Good service, provided by nice staff. The team handled the application process required for the removal of a number of very large lleyandii, plus the removal and stump grinding. Even dealing with having to work around a large amount of waste material and old fencing from previous owners.
