Quick answer: Check the posts first by applying firm pressure. If they wobble at ground level, the post needs fixing before the panel. If posts are solid, remove the damaged panel by unscrewing clips or cutting through nails, then fit the replacement into the groove or brackets, level it, and secure with galvanised fixings. Most panel repairs cost under £30 in materials, well below the £100 to £200 cost of a full replacement.
UK weather is tough on garden fencing, and a panel blown loose or cracked in a storm is one of the most common repair jobs homeowners face. The good news is that fixing or replacing a single panel rarely takes more than an hour, provided the posts underneath are still sound.
Before You Start: Check Fence Ownership
There is no automatic rule in the UK that assigns fence ownership by which side the posts face. The only reliable way to confirm who owns a boundary fence is to check your property’s title deeds and plan, where a T-mark on the boundary line indicates the owner responsible for that section, with the foot of the T pointing towards them. If you are repairing a shared boundary fence, it is worth confirming ownership before starting work, particularly for anything beyond a simple like-for-like repair.
Step 1: Diagnose the Problem
Grab each fence post near the damaged panel and apply firm pressure in both directions.
- If there is movement at ground level, the post itself has failed and needs addressing before you touch the panel. Any panel repair will fail again quickly if the post underneath is not solid.
- If the posts are solid and only the panel is cracked, has blown out of its groove, or has popped its fixings, this is a straightforward panel-only repair.
What You Will Need
- Replacement fence panel, matched to your existing panel width (commonly 1.83m/6ft, though older fences vary)
- Crowbar
- Hacksaw or claw hammer, for removing old nails
- Galvanised panel clips or screws
- Wood preservative, for treating cut edges
- Spirit level
- Safety gloves and eyewear
Step 2: Remove the Damaged Panel
- Check how the panel is fitted. Concrete posts commonly use slotted grooves, while timber posts often use U-shaped fence clips or nails.
- For clipped panels, simply unscrew the clips before lifting the panel out.
- For nailed panels, place a crowbar between the panel and the post and pry gently until the nails are exposed.
- Cut through exposed nails with a hacksaw, or remove them with a claw hammer or pliers, rather than forcing the panel free and risking damage to the post.
- Get help lifting the old panel out if it is large or heavy, and wear thick gloves throughout to avoid splinters and nail injuries.
Step 3: Fit the Replacement Panel
- Measure the gap precisely before ordering a replacement, since panel widths vary between fence styles and ages.
- Treat any exposed cut edges of the new panel with wood preservative before fitting, since untreated edges are the first place rot sets in.
- Slide the new panel into the post groove, or position it against the post if using brackets or clips.
- Check the panel is level using a spirit level, packing underneath with offcuts or bricks if needed to get it sitting correctly.
- Secure the panel with galvanised panel clips or screws, working evenly along both sides rather than fully fixing one side before starting the other.
Fixing a Loose Rather Than Broken Panel
If the panel itself is not damaged but has simply worked loose or dropped slightly, a full replacement is not always necessary.
- Check whether the panel has just slipped in its groove, which is common with concrete post systems and can sometimes be resolved by lifting it back into position.
- If it keeps slipping, fit metal fence panel clips, typically costing £2 to £5 each, screwing them into the post to hold the panel securely in place.
- Use exterior-grade coated or stainless steel screws, generally 5mm in diameter and 50mm to 75mm long, drilling pilot holes with a masonry bit if fixing into concrete posts with plugs.
What Causes Fence Panels to Fail?
Heavy autumn and winter storms put strong lateral pressure on panels, which is why damage tends to spike after severe weather. Waterlogged soil can also rot timber posts from the base upward over time, and repeated freeze-thaw cycles gradually loosen concrete footings across several winters. Fences facing the prevailing south-westerly wind direction common across much of the UK tend to show damage first, and any softwood fence over eight to ten years old is at higher risk of failure at ground level.
When to Address the Post Instead
If your diagnosis in Step 1 showed movement at the post itself, replacing the panel alone will not solve the underlying problem. A leaning or snapped post typically needs either a full replacement or reinforcing with a concrete spur bolted alongside the existing post, which restores structural strength without disturbing the original footing. This is worth treating as a separate job from the panel repair.
Cost Comparison: Repair vs Replace
A straightforward panel repair, whether refitting a loose panel with clips or swapping in a new one, typically costs under £30 in materials when you do the work yourself. Hiring a tradesperson for a full panel replacement, including labour, generally runs to £100 to £200 depending on panel size and access. Acting quickly on a loose or slightly damaged panel, rather than leaving it to worsen, is usually what keeps a repair in the cheaper category.

Frequently Asked Questions
How do I know if my fence panel or the post has failed?
Apply firm pressure to the post near the damaged panel. If it moves at ground level, the post has failed. If the post stays solid and only the panel is cracked or loose, it is a panel-only repair.
Who is responsible for fixing a shared boundary fence in the UK?
There is no automatic rule based on which side faces which garden. Check your property’s title deeds and plan for a T-mark on the boundary line, which indicates the party responsible for that fence.
How much does it cost to fix a fence panel?
A DIY repair, whether adding clips to a loose panel or swapping in a new one, typically costs under £30 in materials. A professional replacement including labour usually costs £100 to £200.
Can I repair a fence panel without replacing the post?
Yes, provided the post itself is solid with no movement at ground level. If the post is loose, leaning, or rotten, address that first, since any panel repair will fail again quickly otherwise.
Final Thoughts
Most broken or loose fence panels are a quick, low-cost DIY fix, provided you check the post is solid before doing anything else. Confirm fence ownership if it is a shared boundary, treat any cut timber edges before fitting, and you will have a secure, windproof fence again within an hour or two.
