I'm extending my garage and as per another thread of mine I've gotten away without needing a bat survey. Yey.
They've just told me I need a Tree survey. Boo.

I'm going to get 2 or 3 quotes but does anyone know what the going rate is? I'm in the North.
Cheers.

I was quoted £700 not long ago for an oak in the south east.

I got 5 quotes and the cheapest was the company just round the corner at £570. They ranged all the way up to over £1k. There was another at £600 but given the first was cheaper and round the corner I've gone for them. Earliest date is the start of June which isn't the end of the world.

How many trees? What sort of area? Do the plans require some trees removing? Are the trees protected or in a conservation area? Do you have a topo showing each tree?

All these things impact the cost of a tree survey

Under 10 definitely, there's 2 larger trees in the garden (a willow and a sycamore) only the sycamore is near the garage at the back, not the end we are extending on. There's some neighbors medium sized trees near that one, I don't know if they get surveyed too?
There's 2 smaller ones that will need removing for the garage extension. No TPO on any of the trees.

Bit late now, but if no tpo or other restrictions, you could have chopped them down before applying

Apparently it's the council's policy to have a tree survey if there's trees on the plot for any work. I can't exactly cut all the trees down haha.

The 2 large ones are pretty large, the lighter one to the left of it is the neighbors side of the fence. The other is a large willow at the other side of the garden.

The tree beards came round today. I chopped down all the trees that I needed removing for the extension. Should get the report next week, hopefully planning are happy with it.

Surveys all done and should be being sent to planning this week. The Root Protection area from the Horse Chestnut behind the garage partly encroaches into the extension area. What's the likely hood of them rejecting the extension because of this? The roots have to go through 6m of original garage foundation to get to the new extension bit.

no RPAs on that plan just shade diagrams and canopy spread

does the plan not come with an AIA to support your application? that is the point of having it, a heads of terms method statement would also be benificial and as well as a TPP.

The key says they are RPAs?


I was told I just needed a survey which is what this is, the BS5837 thing. I'll be a bit fking annoyed if I need more. I'm adding a bit to the garage not building a fking housing estate.

I'll just cut the fker down and build it without planning if they want too much more. I've only got 1 neighbor that can see it and they don't care.

Last minute rant, lack of variety in the swearing, unlikely to follow through with threats. 2/10.

I too would cut it down.

I have an aerial photo of my plot in 1986 and apart from one Ash (now chopped down), everything else is just young trees or saplings.
Today it’s over-grown and needs a bunch cutting back or out really.

Trees don’t live forever, and largely they’re planted in our spaces for amenity.
When they impede amenity they need to go.

If the council artificially impede amenity “because rules” then they have that Horse Chesnut’s sap on their hands!

They grey is definitely the rpa. Ask your tree survey man if the encroachment is ok. You are allowed some encroachment, circa 20% as a guide I believe.

The existing is on it, but it's obviously not having a negative impact, so you can probably argue roots are fully adapted to it. And the rpa is notional,so as you say, it's likely the roots don't actually go through the existing garage.

All this is typically discussed in an arb impact assessment as someone has said. But the validation point is probably the tree survey, so hopefully you get a sensible tree officer.

I'm only a planner saying what I've picked up from Arb experts along the way mind.

The architect has passed it on to the planning department so let's see what they say.
It's a 12m Horse Chestnut with a 700mm diameter trunk. I'll see what the planning say. If it restricts what I can build or comes with exponentially more costs then I'll likely just do it anyway without touching the tree. It's in an enclosed garden and plan on being in this home for atleast 30 years. Really wish I hadn't bothered doing it properly, its supposed to be a quick, cheap project.

I've cut trees down before but nothing that high or big. The one we chopped down where the extension will be was about 9m and came down and through the shredder pretty easily.
