Along the slope or across it
The first question is whether the fence runs down the hill or across it. A fence running down the fall has to step or rack as it goes. A fence running across the fall might stay level along its length, but the ground on one side may sit higher than the other, which means one side of the fence is buried deeper and the base needs thought. It is far easier to plan around a slope you have measured than one you have only guessed at.
Many gardens have both, with a boundary down one side and across the back. Walk the full perimeter and note where the ground rises and where it drops. A quick sketch with rough heights helps, and it makes it simpler to explain what you want. It also shows which parts need a retaining board or a taller gravel board to hold soil back.
Choosing panels for the fall
Stepped panels are the usual answer for modest slopes, as each panel is simply dropped a stage lower than the last. They are easy to source and easy to repair. The cost is the triangular gap at the base, which a gravel board or two will cover.
Racked panels follow the line and suit a longer fall or a boundary that shows from a path. They look neater but need more careful fitting. Where a slope is only slight, you may be able to get away with fitting level panels and letting a deeper gravel board take up the difference, so it is worth asking before assuming the steps are needed. A short chat about the gradient usually makes the right choice obvious.
Posts and the gap at the bottom
Posts should stand at real changes of level, not at random points. If one sits partway down a slope, the panel next to it ends up fighting the ground. Setting the posts first, then measuring each bay, gives a better fit than trying to force standard widths onto uneven land.
The gap at the bottom deserves a decision, not an accident. Some people want it closed, others want a little room for air and drainage. A gravel board cut to follow the soil is the neat way to do either. Where the fence is shared, boundary ownership can vary, so this is general information only. Check your deeds or ask the council if you are unsure. Photos taken along the fence line from each end make it easier for us to see what the ground is doing.
Quick tips
- Sketch the garden with rough heights at each corner so the fall is clear before choosing a panel type.
- Where the ground on one side of the fence sits higher, think about a retaining board to hold soil back.
- Set the posts first and measure each bay afterwards, rather than forcing standard panels onto uneven ground.
- Decide whether you want the bottom gap closed or slightly open, then tell us so the boards are cut properly.

Frequently asked questions
Does it matter whether the fence runs down the slope or across it?
It does. A fence running down the fall has to step or rack as it goes. One running across may stay level, but the ground on one side can sit higher, so that side needs a deeper base or a retaining board to hold soil back.
Where should posts go on a sloping boundary in West Bromwich?
Posts should stand at real changes of level, not at random points, because a post partway down a slope leaves the next panel fighting the ground. Setting the posts first and then measuring each bay fits better than forcing standard widths onto uneven land.
