Shooting squirrels with an air rifle: is it legal in the UK?
Grey squirrels cause significant damage to woodland, agriculture, and native wildlife across the UK. For pest controllers and rural shooters, an air rifle is one of the most practical and accessible tools available for managing them. But before you take a shot, you need to be clear on the legal framework - because getting it wrong carries real consequences. This article sets out exactly what the law requires, what your rifle needs to deliver, and how to stay on the right side of compliance from the first pull of the trigger.
Is It Legal to Shoot Grey Squirrels in the UK With an Air Rifle?
The short answer is yes - but only under specific, well-defined conditions. Grey squirrels are not a protected species in the UK. They are classified as a non-native invasive pest species, and under the Wildlife and Countryside Act 1981, they are not covered by the protections granted to native wildlife. This means you can legally shoot them, provided you meet the other requirements that govern how, where, and with what you shoot, and you understand UK laws on air rifle power, species protection, and humane pest control.
No firearms certificate or special permit is required to shoot grey squirrels with a sub-12 ft/lbs air rifle in England or Wales. In Scotland, you must also hold a valid Air Weapon Certificate, issued by Police Scotland, to possess and use a sub-12 ft/lbs air rifle. You do not need a specific quarry licence in either country. What you do need is landowner permission, a legal and appropriate rifle, and the ability to take humane, accurate shots. Meeting all of these is what defines compliant pest control. This article covers England, Scotland, and Wales. Northern Ireland has separate firearms and wildlife legislation, so check the current requirements with the Police Service of Northern Ireland before shooting there.
No Firearms Certificate Required in England and Wales - But Conditions Apply
Shooting grey squirrels with a sub-12 ft/lbs air rifle does not require a firearms certificate or special quarry permit in England and Wales. In Scotland, you need an Air Weapon Certificate. In every case, you must have landowner permission, operate within legal power limits, and take humane shots that comply with the law protecting wild mammals from cruelty. All of these conditions apply simultaneously - none can be treated as optional.
It is also worth being clear about what the law does not allow. Red squirrels are a fully protected native species under the Wildlife and Countryside Act 1981. Intentionally killing or injuring one is a criminal offence. Positive quarry identification before every shot is therefore essential, not just best practice. If there is any doubt about what species is in your sights, do not shoot.
What the Wildlife and Countryside Act 1981 Says About Grey Squirrels
The Wildlife and Countryside Act 1981 is the primary piece of legislation governing the protection of wild birds, animals, and plants in the UK. Under this Act, intentionally killing or taking any wild bird or protected animal without lawful authority is an offence. Grey squirrels, however, are listed under Schedule 9 of the Act as a non-native species that may not be released or allowed to escape into the wild - but they are not afforded the protections that apply to native wildlife.
This distinction is important. The Act does not grant an open season on all unprotected species. It simply means that grey squirrels are not covered by the prohibitions that protect native animals. The legal permission to control them still depends on the shooter operating lawfully - with appropriate equipment, in the right location, with the required permission.
Red Squirrels Are Fully Protected - Identify Before You Shoot
Red squirrels are fully protected under the Wildlife and Countryside Act 1981. Intentionally killing or injuring one can result in prosecution. In areas where red squirrel populations exist, shooters must exercise extreme caution and positive quarry identification before any shot is taken.
In Scotland, additional legislation applies through the Wildlife and Natural Environment (Scotland) Act 2011, which further regulates invasive non-native species management. Shooters operating in Scotland should be aware of this alongside the 1981 Act. The practical position in all three nations - England, Scotland, and Wales - is that grey squirrel control with a legal air rifle is permitted (with an Air Weapon Certificate in Scotland), but the method and context must comply with the full body of relevant law.
Power Limits and Minimum FPE Requirements for Humane Squirrel Control
England and Wales law sets a maximum muzzle energy of 12 ft/lbs for air rifles that can be owned and used without a firearms certificate. Exceeding this threshold - even marginally - classifies the rifle as a Section 1 FAC air rifle, requiring an FAC. For squirrel pest control, staying within this legal ceiling is both a legal obligation and an entirely practical one - a well-tuned sub-12 ft/lbs rifle, used within effective range, is more than capable of delivering clean, humane results.
The more pressing practical question is not the maximum, but the minimum. There is no legal minimum power for squirrel control, but for humane pest control on squirrel-sized quarry, many experienced shooters treat a rifle operating in the 9 to 12 ft/lbs range as the practical benchmark. This is a widely used rule of thumb rather than a legal requirement, but below this, the energy at the point of impact may be insufficient to guarantee a clean, immediate kill - particularly at anything beyond close range.
Power and Effective Range for Squirrel Control
A sub-12 ft/lbs air rifle in .177 or .22 calibre, operating between 9 and 12 ft/lbs, is appropriate for humane squirrel control within effective range. Shots should typically be limited to 30-40 yards, where energy at the point of impact remains sufficient for a clean kill. Beyond this range, terminal performance drops and the risk of wounding increases, which is a serious animal welfare concern as well as an ethical one.
Calibre choice also plays a role. Both .177 and .22 are used for squirrel control, and each has its advocates. The .22 is generally preferred for pest control at closer ranges due to its heavier pellet and greater energy transfer on impact. The .177, with its flatter trajectory, can extend effective range, but requires precise shot placement to deliver the same terminal effect. In either calibre, pellet selection matters - use quality, match-grade or hunting pellets, not cheap alternatives that sacrifice consistency.
Landowner Permission: What You Need Before You Shoot
Shooting on private land without the permission of the landowner or occupier is trespass, and in some circumstances may constitute a criminal offence. This applies whether you are on agricultural land, woodland, a private garden, or any other private property. Before any pest control work begins, you must have explicit permission from the person who holds the right to grant it.
Permission must come from the landowner or, where the land is tenanted, the tenant or occupier who holds the shooting rights. On some holdings, a farm tenant may not have automatic authority to grant permission if the sporting rights are retained by the landlord. Confirm who actually holds those rights before proceeding, and keep written confirmation with you whenever you shoot.
Permission must come from the landowner, occupier, or the person holding the sporting rights over that land
Written permission is not a legal requirement in all cases, but it is strongly advisable as clear evidence of authorisation
Permission can be withdrawn at any time - it should be confirmed and renewed regularly
On tenanted land, confirm whether the tenant or the landlord holds the shooting rights before proceeding
If challenged on land - by police or any other party - written permission immediately resolves the question of your right to be there
A simple signed letter or agreement detailing the land, the permitted quarry, and the period of permission is sufficient. Renew it regularly to ensure it remains current.
Always Carry Written Permission
Even where written permission is not a strict legal requirement, carrying it protects you in practice. A signed letter from the landowner confirming your permission to control squirrels on their land takes minutes to arrange and can prevent a significant amount of difficulty if your presence is ever challenged.
Shooting Responsibly: Animal Welfare, Shot Placement, and Legal Compliance
In England, Wales, and Scotland, wild mammals are protected from deliberate cruelty by the Wild Mammals (Protection) Act 1996, which makes it an offence to inflict unnecessary suffering on a wild mammal through acts such as beating, stabbing, crushing, or drowning. The Act expressly allows an injured animal to be killed swiftly and humanely in the course of lawful pest control, so dispatching a wounded squirrel promptly is both the right thing to do and fully lawful. If you also use a cage trap, the Animal Welfare Act 2006 applies once an animal is under your control (in Scotland, the Animal Health and Welfare (Scotland) Act 2006 applies). Beyond the law, the responsibility is to ensure that every shot you take is one you are confident will produce a clean, immediate, humane kill, and to understand the wider law for air rifles in the UK that governs where, how, and by whom those shots can be taken.
Shot placement is the most critical variable in humane squirrel control. The accepted target is the head - specifically the area behind and below the ear, or directly to the side of the skull. A well-placed head shot delivers immediate incapacitation without relying on the body shot energy transfer that becomes increasingly unreliable at the edge of your rifle's effective range. Body shots on squirrels are not generally recommended for sub-12 ft/lbs rifles.
Responsible Squirrel Control: Key Principles
Quarry Identification
Confirm beyond doubt that the animal in your sights is a grey squirrel. Red squirrels are fully protected. Take no shot if identification is uncertain.
Range Assessment
Assess the distance to target before shooting. For sub-12 ft/lbs rifles, effective range for humane squirrel control is typically within 30-40 yards. Beyond this, resist the shot.
Shot Placement
Aim for a clean head shot. This is the most reliably humane shot placement for squirrel-sized quarry at sub-12 ft/lbs power levels. Do not take body shots unless you are confident in an immediate incapacitating hit.
Backstop and Safety
Ensure a safe, solid backstop is in place behind the target before shooting. Be aware of what lies beyond. Never shoot where there is any risk to people, property, or non-target animals.
Follow-Up
Retrieve all shot quarry promptly. If an animal is wounded and not immediately incapacitated, act quickly to dispatch it humanely. Never leave a wounded animal.
Effective range discipline is first and foremost an animal welfare matter. Shooting at a squirrel beyond your rifle's reliable effective range increases the risk of a wounding shot, and the discipline to hold back from difficult or marginal shots is part of what separates responsible pest control from reckless behaviour.
A useful illustrative scenario: a pest controller working a woodland edge with a .22 S510 Tactical, set to operate at around 11 ft/lbs, and shooting from a supported position at squirrels presenting within 35 yards. Every shot is taken from a stable position, with a confirmed backstop, at a positively identified grey squirrel presenting a clear head shot. That is compliant pest control - legally sound, practically effective, and carried out in the spirit of both the Wildlife and Countryside Act 1981 and the Wild Mammals (Protection) Act 1996. This represents a typical, well-managed approach rather than any specific documented case.
