Animals (Scientific Procedures) Act 1986

ASPA 1986 · UK Home Office

The UK law controlling the use of dogs and other animals in scientific research, among the strictest regimes in the world.

01 What It Is

The Animals (Scientific Procedures) Act 1986 controls the use of protected animals, including dogs, in scientific research and testing in the UK. Administered by the Home Office, it rests on a principle that animal research is permitted only where its likely benefit is judged to outweigh the harm, and only under license. It is widely regarded as among the most stringent laboratory-animal regimes anywhere.

02 What It Covers

The Act operates a triple-licensing system: a personal license for the individual carrying out procedures, a project license for the program of work, and an establishment license for the place it is done. Each project requires a harm-benefit assessment before it can proceed, and the Act embeds the principle of replacement, reduction and refinement, the “three Rs”, in how research is designed.

03 How It Is Checked

Compliance is overseen by the Home Office through its inspectorate, which assesses license applications and inspects establishments, and licenses can be suspended or revoked. Dogs are a specially protected species under the Act, so their use attracts additional scrutiny and must be specifically justified, beyond the general licensing every procedure requires.

04 Why It Matters

The use of dogs in research is among the most ethically charged things done to them, and one the public cannot see. A strict licensing regime with a harm-benefit test and an inspectorate is what stands between that use and an unregulated one, and the reason a dog cannot lawfully be used in UK research without the case for it having been examined and licensed first.

Common Questions

Is it law?

Yes. The Animals (Scientific Procedures) Act 1986 controls the use of protected animals, including dogs, in scientific research and testing in the UK, and is widely regarded as among the most stringent regimes anywhere.

Who administers it?

The Home Office, through its inspectorate.

How does its licensing work?

Through a triple-licensing system: a personal license for the individual, a project license for the program of work, and an establishment license for the place. Each project requires a harm-benefit assessment before it can proceed.

What about dogs specifically?

Dogs are a specially protected species under the Act, so their use attracts additional scrutiny and must be specifically justified, beyond the general licensing every procedure requires.

How is compliance checked?

The inspectorate assesses license applications and inspects establishments, and licenses can be suspended or revoked. The Act embeds the three Rs: replacement, reduction and refinement.

Why does it matter?

The use of dogs in research is among the most ethically charged things done to them, and one the public cannot see. The regime is why a dog cannot lawfully be used in UK research without the case for it being examined and licensed first.
