Fencing Cost Calculator

If only a panel or two has failed and the posts are sound, repairing is far cheaper — swapping a single panel costs roughly £40–£90 fitted. But once several posts have rotted at the base, or more than a third of the run is failing, a full replacement usually works out better value because the labour to piecemeal-repair adds up. As a rule of thumb, if repairs would cost more than about half the price of a new fence, replace it.

Usually not. Fences up to 2m high are permitted development, dropping to 1m next to a road or vehicle-access footpath. You will need permission for anything taller, and possibly at any height if you are in a conservation area or next to a listed building. Always measure from ground level and include any trellis topper in the total height.

There is no universal left-or-right rule — that’s a common myth. Ownership is set by your title deeds and Transfer plan, where boundaries you maintain are often marked with a “T” on your side of the line. Check your Land Registry title plan, and if it’s genuinely unmarked the boundary may be shared, in which case costs are typically split by agreement rather than obligation.

It depends heavily on type and posts. Cheap overlap panels on timber posts last 8–12 years; closeboard on concrete posts with gravel boards lasts 15–25 years; composite lasts 20–30 years and metal railings 25–40 years. Concrete posts and gravel boards are the single biggest factor in longevity because they stop rot at ground level.
