Usually, yes, if there are large or mature trees close to the house, or the garden carries trees you would become responsible for on completion. There is no legal requirement to have one, and plenty of purchases complete without. But a standard homebuyer report says very little about trees, and once contracts are exchanged, whatever is happening in the canopy or the roots becomes your problem. A pre-purchase tree survey is a choice you make for your own protection, and it is a different thing from the report a mortgage lender sometimes insists on, which we come back to below.
What a pre-purchase tree survey tells you
Our surveyors visit the property and inspect every significant tree: species, size and maturity, structural condition, and any defects such as decay, deadwood, cavities or damage from past pruning. The report then answers the three questions a buyer actually needs answered.
- Condition: which trees are healthy, which are declining, and which have defects that need attention.
- Risk: whether any tree poses a realistic threat to the house, outbuildings, drives, boundaries or the people using the garden, and how urgent that is.
- Likely work: what maintenance or remedial work is sensible, and on roughly what timescale, so you can weigh it up before exchange rather than discover it afterwards.
A good survey is not a scare document. Mature trees are usually an asset to a property, and the most common outcome is a short, manageable list of routine work. The point is to know what you are taking on while you can still negotiate, budget or walk away.
When it is worth commissioning one
It is a judgement call, and for a modern house with a couple of small ornamental trees the honest answer is that you probably do not need one. It becomes much more sensible when any of the following apply:
- large trees stand within falling distance of the house, garage or parking
- the garden is mature and you have no history for the trees in it
- trees sit on or close to a boundary, where responsibility can be shared or disputed
- there are visible signs of decline, storm damage or heavy past pruning
- the property is in a conservation area, or the trees may be protected
Protection matters more than most buyers expect. Working on a protected tree without consent can lead to fines, which for the most serious breaches can be unlimited, and the protection stays with the trees when the property changes hands. Our guide to whether a tree is protected explains how to check, and the council’s register is the definitive record.
How this differs from a report your lender demands
Sometimes there is no choice to make. A mortgage valuer who notes a large tree near the building can make the loan offer conditional on a tree report, usually because of concerns about the tree’s influence on the structure. That is a narrower, lender-driven exercise with its own requirements, and we have covered it separately in our guide to mortgage tree reports. This post is about the opposite situation: nobody is demanding anything, and you are deciding whether to look before you buy. A buyer-commissioned survey is broader. It considers the condition and management of the whole tree stock, not just whichever tree caught the valuer’s eye, and it is written for you rather than for the bank.
Will it hold up the purchase?
Chain speed is the usual worry, and it is a fair one. In practice a tree survey sits comfortably inside the conveyancing timetable. Our team books survey visits within days, and the report follows days after the visit, not weeks. Before any of that we run a free scope check to confirm what the property actually needs, and the quote that follows, within one working day, is all in: the price we quote is the price you pay.
One more point worth knowing. Although Great Oaks also carries out tree work, the survey does not depend on it. The report stands alone, it is never conditional on us being hired to do anything it recommends, and you are free to take it to any contractor you choose. We are an ARB Approved Contractor (AC2637), we carry professional indemnity insurance for our survey work, and our surveyors cover Preston, Lancashire and the wider North West as part of our tree survey service.
If you are weighing up a purchase and cannot tell whether the trees justify a survey, or a lender or council has asked for something and you are not sure what, use the free scope check form on our tree surveys page or call 01772 369694. We will tell you what you need, and just as readily what you do not.
