Hedgehog-Friendly Gardens: Houses, Hedgehog Holes and Hazards
Practical steps and the best buyable houses to help hedgehogs survive the long slide into hibernation.
If there's one wild visitor I never tire of finding at the bottom of the garden on a damp autumn evening, it's a hedgehog snuffling through the leaf litter. They're one of our most beloved garden mammals, and yet they're having a genuinely hard time of it — populations have tumbled across the British countryside over the last couple of decades, and suburban gardens have quietly become some of their most important strongholds. The good news? Your patch can make a real, measurable difference, and most of what you need to do costs very little.
In this guide I want to walk you through the three pillars of a properly hedgehog-friendly garden: giving them a house to shelter and hibernate in, cutting hedgehog holes so they can roam freely between gardens, and removing the everyday hazards that injure or kill far more hogs than most of us realise. I'll also go through the specific hedgehog houses worth your money as we head into the hibernation season, with honest thoughts on which ones earn their keep.
Why Autumn Is the Critical Window
Hedgehogs typically enter hibernation somewhere between November and the first sustained cold snaps, though milder winters increasingly muddy the timeline. The weeks before that are the single most important period of their year. A hog needs to build up enough fat reserves to survive months of torpor, and it needs a dry, sheltered, undisturbed nest — a "hibernaculum" — to do it in. Anything you provide between September and November lands at exactly the right moment.
This is why so much hedgehog advice clusters around autumn. It isn't that a house in spring is useless (it absolutely isn't — they'll use it to raise hoglets too), but a house, a feeding station and a clear run between gardens installed now can be the difference between a hog that wakes up in March and one that doesn't.
A hedgehog you spot out in broad daylight, especially one that's small, wobbly or sunbathing, is usually in trouble. Contact a local rescue or the British Hedgehog Preservation Society rather than waiting to see if it sorts itself out.
Hedgehog Houses: What Actually Matters
A hedgehog house — sometimes sold as a hog home, hibernaculum or hedgehog box — gives a hog a ready-made, predator-resistant shelter that it can line with leaves and bed down in. You can build one from an old wooden crate, and plenty of people do, but a well-designed bought house saves time and tends to last longer through repeated wet winters.
Before we get to specific models, here's what genuinely separates a good house from a gimmicky one. Ignore the cutesy painted finishes and focus on these features:
An entrance tunnel or baffle
A short internal tunnel or right-angled baffle stops cats and foxes reaching straight in to grab a sheltering hog. This is the single most important design feature, and the budget boxes that skip it aren't worth buying.
A sloped, waterproof roof
Rain is the enemy. A pitched or felted roof that sheds water keeps the nest dry. Damp bedding is worse than no house at all.
Some ventilation
A small vent or air gap prevents condensation building up inside, which would otherwise leave the bedding clammy.
FSC or sustainably sourced timber
Untreated or animal-safe treated wood is essential — you don't want chemicals leaching near a sleeping animal. Solid timber also outlasts thin plywood.
A removable lid for cleaning
Once a hog has moved out, you'll want to clear old bedding before the next occupant. A hinged or lift-off roof makes annual maintenance painless.
Pro Tip
Site the house with its entrance facing north or north-east, away from prevailing wind and rain, and tuck it under a hedge, shrub or against a fence. Cover the roof with leaves and a bit of brushwood to make it feel natural — a house plonked in the open middle of the lawn rarely gets used.
The Houses Worth Buying This Autumn
There's a surprisingly wide field of hedgehog houses on the UK market, ranging from rough-and-ready budget boxes to handsome, properly engineered shelters. Below are the models I'd point friends towards, grouped by what you're actually paying for.
Wildlife World Hedgehog House
At £99.99, the Wildlife World Hedgehog House sits at the premium end and looks the part. It's the one to consider if you want a house that disappears into a planted border and is built to last several seasons of British weather. For a focal-point garden where you don't want an obvious plastic box, it's an easy recommendation.
Hogilo Hedgehog House
The Hogilo Hedgehog House comes in at £69.99 and pitches itself squarely at people who want a thoughtfully designed, predator-aware home without going all the way to the top of the range. It's a sensible middle-ground pick.
RSPB Hedgehog House
At £55.00, the RSPB Hedgehog House carries the reassurance of a conservation brand behind it, and buying it supports wildlife work. It's a dependable mid-priced option for gardeners who like knowing where their money goes.
Gardenature Hedgehog House
The Gardenature Hedgehog House lands in the £35–45 bracket, making it one of the more accessible "proper" houses rather than a token budget box. If you want something legitimately functional without spending a small fortune, this is the value sweet spot.
Other names worth a look
Riverside Woodcraft produces a well-regarded hedgehog house with a craft-built feel, The Hutch Company offers its own version, and Henry Bell makes a wooden hedgehog house that turns up widely. There are also various budget options in the £15–35 range — fine as a starting point, but check carefully that they include an entrance baffle and a genuinely waterproof roof before committing.

Whichever house you choose, don't be disappointed if it sits empty for a while. Hedgehogs are fussy, and it can take a season or two before one decides your box is home. Patience is part of the deal.
Hedgehog Holes: The Highway You Can't See
Here's the thing most people get wrong: even a perfect house is nearly useless if a hedgehog can't reach it. Hogs are astonishing travellers, covering up to a couple of kilometres in a single night as they forage. That range only works if they can move freely between gardens — and the modern obsession with solid, gap-free fencing has effectively walled them out of huge swathes of suburbia.
The fix is gloriously simple and is the heart of the national "Hedgehog Highways" effort. Cut a 13cm by 13cm hole at the base of your fence or gate — roughly the size of a CD case. That's big enough for a hedgehog to pass through comfortably but too small for most pets to follow. Then, ideally, persuade your neighbours to do the same, so the holes line up into a continuous corridor.
Stick to 13×13cm
It's the established standard — wide enough for any hedgehog, including a chunky autumn male, but small enough to keep out most cats and to reassure nervous neighbours.
Connect with neighbours
One hole helps a little; a row of linked holes across several gardens transforms an isolated patch into part of a living network. It's worth a friendly knock on the door.
Frame it neatly
A purpose-made hedgehog hole plate or a tidy timber surround keeps the gap from looking like damage and stops the fence panel weakening over time.
Renting or sharing a fence?
If the fence isn't entirely yours, a small gravel board gap, a ramp over a low wall, or simply leaving a gap where a fence meets a path can all do the job without altering anyone's property. There's almost always a workaround.
The Hazards Hiding in Plain Sight
This is the section I most wish every gardener would read, because the everyday features of a tidy garden cause an enormous amount of hedgehog suffering — and nearly all of it is avoidable once you know what to look for.
Ponds and pools
Hedgehogs can swim but tire quickly, and steep, smooth sides become a death trap. Add a sloped ramp, a half-submerged brick stack, or some chicken-wire draped over the edge so a hog can always climb out.
Bonfires
An unlit bonfire pile is exactly the dry, sheltered nest a hog dreams of. Always build it on the day you burn it, or move it pile-by-pile to fresh ground first, checking carefully as you go.
Slug pellets & pesticides
Chemicals poison the slugs and insects hedgehogs eat — and can poison the hog directly. Skip them entirely; a healthy hedgehog is a far better slug controller than any pellet.
Strimmers & mowers
Hogs curl up rather than flee, so they're horribly vulnerable to blades in long grass. Always check thoroughly under hedges and in long growth before strimming or mowing.
Netting & litter
Loose football nets, pea netting and discarded plastic ties trap and strangle hedgehogs. Keep netting taut and well off the ground, or store it away when not in use.
The wrong food
Never put out milk or bread — hogs are lactose intolerant and bread offers no nutrition. Meaty cat or dog food, or proper hedgehog food, plus a shallow dish of fresh water, is what they actually need.
Drain covers, uncovered gully pots and deep window wells trap hedgehogs that fall in and can't climb out. A quick walk round the garden to cover or ramp these spots takes ten minutes and saves lives.
Building the Whole Picture: House, Food and Water
A house works best as part of a small ecosystem of support. Pair it with a feeding station and you give an autumn hog the calories it needs to fatten up before hibernation, plus a reason to keep returning to your garden.
A feeding station can be as simple as an upturned storage box with a 13cm doorway cut into it, weighted down so foxes and cats can't barge in. Inside, place a shallow dish of meaty pet food or hedgehog food and a separate dish of water — never milk. Position it in a quiet corner, ideally on the route between your hedgehog hole and the house.
I find that ranking useful because it gently corrects a common instinct: people rush to buy a house first when, honestly, cutting a hole and clearing hazards delivers more for hedgehogs and costs almost nothing. The house is the lovely finishing touch on a garden that's already safe and accessible.
A house gets you
- A ready-made, predator-resistant winter shelter
- A potential nursery for hoglets in spring
- Years of use if it's solid timber and felted
- A focal point that supports wildlife
But remember
- It may sit empty for a season or two
- It's useless if hogs can't reach your garden
- Cheap boxes without a baffle offer false security
- Damp, poorly sited houses do more harm than good
How I'd Rate the Approach
Taking the whole hedgehog-friendly garden strategy as one package — house, holes and hazard removal together — here's how it stacks up across the things that matter.
The only reason it isn't a clean ten is that success partly depends on factors beyond your control — neighbouring gardens, local hog numbers, and a fair dose of patience. But the upside is enormous relative to the effort, and almost everything here benefits other wildlife too.
Who Should Do What
The thrifty gardener
Start with a hedgehog hole and hazard-proofing — both free or near-free — then add a Gardenature house in the £35–45 range when budget allows.
The wildlife enthusiast
Go the full distance: house, feeding station, water dish and a connected highway. The Hogilo at £69.99 or Wildlife World at £99.99 are worthy centrepieces.
The conservation-minded
The RSPB Hedgehog House at £55.00 pairs solid function with support for wider wildlife work — a feel-good middle path.
The hands-on type
Happy with a saw? Build your own house and feeding station, then spend the savings on quality hedgehog food through the autumn.
Frequently Asked Questions
The Verdict
Helping hedgehogs is one of the most rewarding things you can do in a garden, and it doesn't demand deep pockets or a sprawling plot. The single biggest move is the cheapest: cut a 13×13cm hole so hogs can actually reach you, and clear away the ponds, pellets, nets and bonfire risks that quietly do so much damage.
Once your garden is safe and accessible, a good house turns it into a place a hedgehog might genuinely call home through the winter. If budget is tight, the Gardenature house at £35–45 is a smart, functional starting point. Step up to the Hogilo at £69.99 or the conservation-backed RSPB house at £55.00 for a thoughtful all-rounder, or go for the Wildlife World house at £99.99 if you want a premium shelter that melts into a planted border for years to come.
Whatever you choose, do it now. The weeks before hibernation are precious, and a little effort this autumn could be exactly what carries a hedgehog safely through to spring.
