The short answer
Yes, you can usually replace a single fence panel — it is one of the most common fence repairs in the UK. How easy it is depends mainly on the posts: with slotted concrete posts, the old panel lifts out and a new one drops straight in, no fixings needed. With timber posts, the panel is unscrewed from the rails or brackets and a like-for-like replacement is fitted. The two things to get right are matching the size (standard panels are about 1.8m wide but heights vary) and accepting that a new panel will look fresher than the weathered ones around it until it greys to match. If the posts either side are rotten, you may need to replace those too.
Swapping a single panel after isolated damage is a routine job, and far lower-cost than replacing a whole run. The post type is what decides how straightforward it is.

How the post type decides the job
The single biggest factor in replacing one panel is what holds it in place:
- Slotted concrete posts: the easiest case. The panel sits in grooves in the posts; you lift the damaged panel up and out, then slide the new one down into the slots. No fixings, no groundwork.
- Timber posts with brackets or clips: the panel is screwed to brackets or clipped to the posts. You undo the fixings, remove the panel, and fit the new one with fresh fixings.
- Closeboard on rails: if the fence is built as featheredge boards on rails rather than pre-made panels, you replace damaged boards individually rather than a whole 'panel'.
If the posts are sound, any of these is a manageable single-panel job. The work only grows if a post either side has also failed.
Matching the replacement panel
Getting a replacement that fits and looks right takes a little checking. The key points:
| Check | Why it matters | Tip |
|---|---|---|
| Width | Must fit between posts | Standard ~1.83m, but measure the gap |
| Height | Heights vary (e.g. 1.5m, 1.8m) | Match existing height |
| Style | Overlap vs closeboard vs T&G | Match the run's appearance |
| Thickness | Slotted posts take set widths | Check it fits the slot |
Indicative guidance only. Always measure the actual gap and existing panel before buying a replacement.
When a single swap is and isn't enough
Replacing one panel is the right move in many situations, but not all. A quick guide:
- Isolated storm or impact damage: one panel cracked or blown out of sound posts — a single swap is ideal.
- Accidental damage: a panel holed by a ladder or mower, posts fine — replace just that panel.
- Rotten post alongside: if a post either side is soft, replace the post at the same time, which adds groundwork.
- Several tired panels: if neighbouring panels are also near the end, doing them together spreads the call-out and may be better value.
- Whole run failing: if the posts and panels are widely rotten, a single swap is a sticking plaster on a fence that needs replacing.
The honest test is whether the rest of the fence has real life left. If it does, a single panel swap is a sensible, low-cost repair; if the run is failing throughout, the money is better put towards replacing it.
Matching a new panel to the old fence
The trickiest part of a single-panel swap is often not fitting it but getting it to match, and a mismatch is the most common regret afterwards:
- Measure the gap, not a catalogue: standard panels are nominally 1.83m wide, but post spacing varies, so measure the actual opening between your posts before buying.
- Check the height and style: overlap, closeboard and tongue-and-groove look different; matching the existing style keeps the run consistent.
- Account for the gravel board: if the rest of the run sits on a gravel board, the new panel must allow for the same, or it will sit at a different height.
- Expect a colour difference: a fresh panel is lighter and brighter than weathered neighbours and will stand out for a season or two until it greys to match; a coat of matching stain narrows the gap sooner.
- Confirm the fixing type: slotted concrete posts take a panel straight in, while bracketed timber posts may need clips or battens to suit.
Getting the size and style right first time avoids the frustration of a panel that will not seat properly or visibly clashes with the rest of the fence, which is the usual reason a simple swap turns into a return trip.
Doing it yourself versus calling a fitter
A single-panel swap into sound posts is one of the more achievable fence jobs for a competent DIYer, but there are reasons to weigh it up:
- Slotted concrete posts: often a genuine DIY job — lift out, drop in — though panels can be heavy and awkward for one person.
- Bracketed timber posts: straightforward if you are comfortable with a drill and getting the panel level.
- Heavy panels: composite and tongue-and-groove panels are weighty and usually need two people to handle safely.
- A post to replace too: if groundwork is involved, the job moves from simple swap to setting a post in postcrete, which is harder to get plumb and may justify a fitter.
- Minimum call-out: a fitter has a minimum charge for one panel, so the per-panel cost is higher than in a full run — another reason to bundle several if more are due.
The practical summary is that replacing one panel is not only possible but common, and usually quick and low-cost when the posts are sound. Check the size and style carefully, accept that the new panel will look fresher for a while, and only widen the job if a post has failed or the surrounding run is also near the end of its life.
Frequently asked questions
Do replacement fence panels come in standard sizes?
Largely, yes. The standard width is about 1.83m (6ft) to fit between posts at standard spacing, while heights vary — common ones include 1.8m, 1.5m and 1.2m. Always measure the actual gap between your posts and the height of the existing panel before buying, as older fences and non-standard installations can differ from the usual sizes.
Why does my new fence panel look different to the rest?
Because fresh timber is much lighter in colour than panels that have weathered to grey over years of sun and rain. The contrast is normal and fades as the new panel ages, usually toning down over a season or two. Treating it with a stain close to the existing colour can reduce the difference while it weathers in.
Can I replace a panel if the post next to it is rotten?
You can, but it is better to replace the rotten post at the same time. Fitting a new panel to a failing post means it will not be held securely and may come loose or fall in wind. Replacing the post adds groundwork — digging out the old footing and setting a new post in postcrete — but it gives the new panel something sound to sit in.
