What is the 2m fence rule?

The limit applies to the whole structure. Class A restricts the height of any gate, fence, wall or other means of enclosure, and the Order contains no separate allowance for trellis, toppers or post caps. So a 2 metre fence with 300mm of trellis on top is a 2.3 metre means of enclosure, and the common claim that you can add trellis above the limit without permission has no support in the Order. If you want 2.3 metres of screening, either apply for permission or plant something behind a fence that complies.

Height is measured above ground level, which becomes the argument on sloping ground. The Order's general approach, where the surface is not uniform, is to measure from the highest part of the adjacent ground. That wording is written around buildings rather than fences, so on a split-level or terraced garden, and Cheltenham has plenty of both, treat it as the likely position and confirm with Cheltenham Borough Council before ordering materials. A fence that reads 1.9 metres on your side can be well over 2 metres measured from a neighbour's lower ground.

Several things switch the allowance off entirely. Within the curtilage of a listed building, or where the fence forms a boundary with a neighbouring listed building or its curtilage, Class A does not apply at any height, so even a low fence needs permission. Permitted development rights can also be removed by an Article 4 direction, or by a condition on the original planning permission. That second one catches new-build estates constantly, particularly open-plan frontages, so check the conditions attached to the estate permission before assuming the national rules apply.

An existing taller fence has its own rule. Class A allows a fence to be maintained, improved or altered without exceeding its former height, so a lawful 2.4 metre fence can be repaired and kept at 2.4 metres. What the Order does not settle is whether taking the whole thing out and building new counts as maintenance or as fresh erection, which would bring the 1 and 2 metre caps back. Nobody should tell you that is definitely fine. Where it matters, apply to the council for a lawful development certificate and get a binding answer.

In practice most of what we install sits at 1.8 metres, the standard panel and closeboard height, which keeps you inside the limit with room to spare on level ground. Gravel boards count towards the total, so a 1.8 metre panel on a 150mm concrete gravel board measures 1.95 metres before any post cap goes on. Tell us which boundary you want fenced and whether it faces a road, and we will set out heights that stay within permitted development, or say plainly that you need to ask the council first.
