If you've ever walked your fence line on a frosty morning and found posts leaning, cracked, or snapped in half, you're not alone. Broken electric fence posts are one of the most common frustrations for UK farmers, horse owners, and smallholders.
But why do posts break so often, and more importantly, how can you stop it happening? In this guide, we'll dig into the main reasons posts fail, and share practical tips for keeping your fence upright year-round. We'll also explain why investing in better-quality posts from brands like Gallagher and Hotline can save you money and headaches in the long run.
The Top Reasons Electric Fence Posts Break
1. Frost and Cold Weather
Cheap plastic posts are notorious for snapping in winter. The plastic becomes brittle in freezing temperatures, and even a small knock — from livestock, wind, or you tapping them in with a mallet — can cause them to crack at the base.
2. Poor Ground Conditions
Soft or waterlogged soil makes posts lean, while stony or compacted ground puts too much stress on the shaft when driving posts in. Both lead to breakages if the post isn't designed to handle that environment.
3. Livestock Pressure
Cattle rubbing, horses leaning, or sheep testing the fence can put huge force on posts. Lighter posts bend or snap quickly under repeated pressure.
4. UV Damage
Over time, sunlight degrades cheap plastics. Posts that looked fine in year one can become chalky and brittle by year three, snapping with the slightest stress.
5. Weak Footplates
A lot of budget plastic posts have thin, weak foot treads. These either snap off when you push them into hard soil, or they provide so little support that the whole post leans after a bit of wind.
How to Prevent Post Breakages
The good news is that most of these problems can be avoided.
Choose Quality Posts
Premium posts are made from UV-stabilised plastics that resist sunlight damage, with reinforced shafts and footplates. Gallagher and Hotline posts are designed with thicker plastic moulds, making them less prone to snapping at the ground line.

Use the Right Post for the Right Job
- Plastic posts are best for temporary runs or light stock.
- Wooden or steel posts should anchor corners, gateways, and high-pressure areas.
- Fibreglass posts are ideal for horse paddocks where flexibility and safety matter.
Mixing post types is the best way to get strength where you need it and save money where you don't.
Install Posts Correctly
Driving posts too shallow or forcing them into stony ground with excessive hammering is a recipe for cracks. Use a post driver for steel or timber, and don't be afraid to reposition if you hit resistance.
Maintain Your Fence Line
Check your posts regularly. Replacing one leaning post before it snaps is far cheaper than letting a whole section collapse. Clearing vegetation also stops unnecessary strain on posts and conductors.
Why Gallagher and Hotline Posts Last Longer
It's not just marketing — the difference is in the build quality.
- Gallagher posts are thicker than most budget posts, with UV stabilisation that means they don't turn brittle in the sun. Farmers often report them lasting two to three times longer than cheaper alternatives.
- Hotline posts (a trusted British brand) are designed for mixed UK conditions. Their multi-wire posts are especially popular with sheep and goat keepers because they stay upright in soft ground better than cheaper versions.
Yes, you'll pay more up front. But instead of replacing half your posts every other winter, you can rely on them for years. Over a decade, Gallagher and Hotline posts nearly always work out cheaper — and far less hassle.
Final Word: Prevention Is Cheaper Than Cure
Broken electric fence posts are frustrating, time-consuming, and in some cases dangerous if stock get loose. Most failures come down to using the wrong posts for the job, cutting corners on quality, or poor installation.
Spend a little more on robust posts from trusted brands like Gallagher and Hotline, mix in timber or steel at the stress points, and install carefully. You'll spend less time repairing your fence and more time focusing on your animals.
