Most people only start thinking about their garden fence when a panel blows over in a January storm and lands on the neighbour’s car. It’s one of those things that gets ignored until it becomes urgent, and that’s usually when the decisions get rushed and the costs get painful. Taking a bit of time to understand what you actually need before anything breaks makes a genuine difference, both to your wallet and the finished result.
The UK weather is, let’s be honest, relentless on timber. That pressure-treated fence that looked great when it went in five years ago can start looking seriously rough by year seven, especially if it’s catching the prevailing wind or sitting in a patch of ground that doesn’t drain properly. Rot often starts at the base of posts, not the panels, which is why so many people replace perfectly good panels and then find themselves back to square one eighteen months later when the posts give way.
Posts First, Everything Else Second
If your fence is going up fresh or coming down to be replaced, the posts are where you should be spending your thinking time. Concrete posts are heavier and slightly more expensive upfront, but they don’t rot and they don’t shift the way timber does over time. Timber posts are easier to cut and work with on site, and they look better in some settings, but they need to be pressure-treated to at least UC4 standard if they’re going in the ground. A lot of people pick up cheaper posts without checking this and then wonder why things look rough within a few years.
Post depth matters too. The general rule is about a third of the total post length should be in the ground, so a 1.8m high fence needs a post that’s around 2.4m long in total, with roughly 600mm below ground level. Plenty of DIYers underestimate this and end up with posts that lean under any real wind pressure. Worth getting right before you mix a single bag of postcrete.
Choosing the Right Panel Type for Your Garden
Lap panels are the classic choice across British gardens, and they’re popular for good reason. They’re affordable, widely available, and look decent once stained, but they’re not the most durable option, particularly in exposed positions. Featherboard fencing, where each board overlaps the one below it and everything is fixed to a solid frame, tends to hold up a lot better and can be built to almost any height or width. It’s more work to put up, but you’re building something that’ll actually last rather than something you’ll be replacing again in a decade.
Closeboard is another solid option if privacy is the priority and you want something a bit more substantial than lap panels. The boards are individually nailed to horizontal rails fixed to the posts, so there’s no single weak point the way there is with a panel that can effectively take a fence section down in one go if it goes. When you’re pulling together your garden fencing supplies, it’s worth thinking about whether you’re buying for convenience or buying for longevity, because those two things often point toward different products.
Gravel Boards and Why They Actually Matter
Gravel boards sit at the base of the fence between the posts, keeping the panels or boards off the soil. They take the brunt of moisture and ground contact so your actual fence doesn’t have to. A lot of people skip them and then watch the bottom of their panels go black and soft within a couple of years. Concrete gravel boards are the most durable, though they’re heavy and a bit of a pain to manoeuvre if you’re doing this solo. Composite ones are lighter and look fine once everything’s up.
Treated timber gravel boards do the job too, and they’re the cheapest route, though they’ll need replacing eventually. None of these options are glamorous, and they’re mostly invisible once the fence is up, which is probably why so many people talk themselves out of including them. That’s usually a decision they regret.
A Few Practical Things Worth Knowing
Check your title deeds or the Land Registry before assuming which fence is yours to replace. The convention that the left-hand fence belongs to you when you’re standing in the garden looking at the house is widely believed but not actually a legal rule. Getting into a dispute with a neighbour over who pays for a fence panel is genuinely one of the more miserable experiences suburban life can offer.
Also, if your fence adjoins a highway, there may be height restrictions to consider. Anything over one metre next to a road technically requires planning permission in most cases, and councils do occasionally follow up on this, particularly in areas where they’re already looking at a property for other reasons.
