   Awaiting decision

   Decision expected by 30 October 2026, 8 weeks from validation under the statutory target for most applications. Extensions of time are common and are agreed case by case.

   Haringey took a median of 53 days over the applications it decided in the last year.

This application is with Haringey for determination. The council publicises it, consults neighbours and technical bodies where required, and weighs the responses against local and national planning policy.

The statutory target is eight weeks for most applications and thirteen for major development, though extensions of time are common. Comments carry most weight while the case is undecided, so check the council portal for the deadline if you want to respond.

Tree applications cover work to protected trees: those under a tree preservation order need consent for pruning or felling, and trees in a conservation area need six weeks written notice before work starts. The council assesses the amenity value of the tree and can refuse consent, approve it with conditions, or in conservation areas make a preservation order in response.

  Proposal: We are proposing to have the large lime tree at the bottom of our garden pruned professionally, as part of the cycle of regular pruning. The proposed work is a 30% crown reduction and thinning back to previous reduction points. I would estimate that the tree is about 15 metres high, so we are requesting a reduction of some 4-5 metres. The tree was last pruned in 2021 under your reference CON/2021/0518: it is in a Conservation Area, but not subject to a Tree Preservation Order.
