Do You Need a Dog Breeding Licence? The UK Rules Explained
In England, you need a dog breeding licence if you breed three or more litters in any 12-month period and sell at least one puppy. You also need one if you breed dogs and advertise a business of selling them, even if that means only one or two litters. Wales, Scotland and Northern Ireland each have their own rules. The tests below will show you which applies to you.
Licensing is one of the most searched and least understood parts of dog breeding. Every listing on Puppies.co.uk is reviewed by our team before it goes live, so we see the same confusion again and again: breeders who are sure a £1,000 limit protects them, hobby breeders worried they're breaking the law when they aren't, and the occasional seller who really should hold a licence and doesn't.
The two tests, explained simply
In England, the law sets two separate gates. You only need to pass through one of them to need a licence.
Gate one: the litter test. You need a licence if you breed three or more litters of puppies in any 12-month period. The exception is if you can prove that none of the puppies has been sold, either as puppies or as adults. That proof has to include records of the new owners of every puppy and an explanation of why no transaction took place, including payment in kind.
Gate two: the business test. A licence is needed for a breeding business regardless of how many litters it produces. This isn't limited to registered businesses, and individuals can be classed as a business depending on the extent of their activities.
Answer these to find out (England)
Have you bred, or will you breed, three or more litters in the last 12 months?
If yes, and any puppy has been or will be sold, you need a licence. If yes but you have documented evidence that none were sold, the litter test doesn't apply. If no, go to question 2.Is your gross income from breeding and selling dogs under £1,000 in the tax year?
If yes, DEFRA's guidance says you don't need a licence under the business test. If no, go to question 3.Does your activity look commercial?
Think about frequent or repeated sales, lots of adverts, several breeds, or high prices and margins. If it does, speak to your council before your next litter. If it clearly doesn't, a licence is unlikely to be needed. The council is still the only body that can confirm this.
Remember that the litter count covers every litter you breed, including ones you keep or give to family. What changes the outcome is whether any puppy is sold.
The £1,000 "rule": half true, and the half people miss
The £1,000 figure is the HMRC trading allowance, a tax rule. It lets individuals earn up to £1,000 a year in gross trading income tax-free, and anyone with gross trading income over £1,000 must register for Self Assessment.
It entered the licensing conversation because DEFRA's guidance refers to it. The guidance says that someone with trading income below the HMRC allowance doesn't need a licence, and that someone above it doesn't automatically qualify as a business. So the "rule" is real, but it is narrower than most people think. Three points matter.
It doesn't override the litter test. The Royal Kennel Club's reading of the guidance is that income under £1,000 a year means no licence is needed, unless you are over the litter threshold. Three litters with a sale means a licence, whatever you earn.
It's measured on income, not profit. The allowance applies to gross takings before costs. At current puppy prices, a single small litter can pass £1,000 on its own.
Crossing it doesn't make you a business. Breeders can take well over £1,000 and still make a loss once stud fees, food and vet costs are counted. Neither the regulations nor the statutory guidance set an income or profit figure at which the business test is triggered.
In short, going over £1,000 is a tax matter first. It prompts a closer look at whether you're trading, but it doesn't automatically mean you need a licence.
What counts as "running a business"? The badges of trade
Councils decide whether breeding is a business using two things: HMRC's nine "badges of trade", which apply to any activity, and DEFRA's dog-specific indicators. Under DEFRA's guidance, inspectors look at whether the operator makes any sale or carries out the activity to make a profit, and whether they earn any commission or fee from it.
DEFRA's practical signs that someone may be advertising a business include:
systematic, repeated sales using the same means of advertising
high volumes of animals sold or advertised, or low volumes where prices or profit margins are high
large numbers of adverts, including on classified websites, even where no sale results
advertising across several sites, forums or media
BASC offers a useful rule of thumb. Compare what a litter costs you (stud fees, food, registration, vet fees) with what the puppies sell for. If you roughly break even, BASC's view is that you are not running a business. It also warns that selling even a few puppies at a high price could flag the need for a licence. Treat this as a sense-check rather than a legal test, and keep your receipts either way.
The rules by nation
England: A licence is needed for anyone breeding three or more litters in 12 months and/or anyone who breeds dogs and advertises a business of selling them.
Wales: A licence is needed where a breeder keeps three or more breeding dogs and breeds, advertises or supplies puppies from three or more litters in 12 months, or advertises a business of breeding or selling puppies. Wales also has a separate pet vending regime. It may require some breeders who sell one or two litters a year to hold a pet vending licence if their sales are in the course of business. Its guidance is clear that genuine hobby breeders selling occasional surplus puppies are out of scope. Those regulations came into force on 10 September 2021.
Scotland: Anyone breeding three or more litters in 12 months must be licensed, whether they sell the puppies or supply them in some other way. This threshold came into force on 1 September 2021, down from five litters. Scottish licences last one, two or three years, with the council deciding the length and the cost.
Northern Ireland: A licence is needed where a breeder has three or more breeding dogs and breeds, advertises or supplies three or more litters in 12 months, or advertises a business of breeding or selling puppies. These rules have applied since 1 April 2013.
Star ratings and what they mean (England)
England's star rating system is one of the few parts of licensing that openly rewards good practice. A licensed breeder's rating depends on two things: the welfare standards they work to, and their risk rating, which reflects their history of meeting those standards.
To reach the higher standards, a breeder must meet every required higher standard and at least half of the optional ones. In return, they get a licence lasting two or three years instead of one, and a lower fee. A low-risk rating needs at least a year of maintained standards. Complaints and the quality of record-keeping are also taken into account. In practice, first-time applicants are unlikely to be rated low risk straight away. Four stars is a very good first result.
How to apply for a licence
Contact your local council. Licensing is handled locally. Use gov.uk's find your local council tool, and ask whether they offer pre-application advice.
Read the conditions before you apply. In England, these are Schedules 2 and 6 of the 2018 Regulations and DEFRA's statutory guidance. They cover housing, exercise, feeding, health, socialisation and emergency provision.
Get your paperwork in order. You will need written procedures covering feeding, cleaning, transport, disease control, health monitoring, and what happens if an animal dies or escapes. You will also need a registered vet, a preventative healthcare plan agreed with them, a socialisation programme and full records.
Pay the fee. Fees are set by each council and vary widely.
Be inspected. In England, a vet must be appointed for the first inspection of a dog breeding licence application.
Receive your decision and rating. Display your licence, and keep your council informed. DEFRA's guidance asks licensed breeders to tell their licensing authority, by email or phone, each time a litter is whelped.
What a licensed breeder must put in every advert
This is where licensing and selling meet. In England, any advert for a dog must include the licence number, the local authority that issued it, a recognisable photograph of the dog being advertised, and its age. The licence holder's name and licence number must also be displayed clearly on any website used for the activity.
Licensed breeders must also follow these rules:
No puppy under 8 weeks old may be sold or permanently separated from its mother.
A puppy may only be shown to a buyer together with its mother, unless separation is needed for health reasons.
Every puppy must be microchipped and registered to the licence holder before it is sold.
If you're buying, a missing licence number on an advert from someone who clearly breeds often is worth asking about politely. There may be a simple explanation. If there isn't one, that tells you something too.
What happens if you breed without a licence?
In England, carrying on a licensable activity without a licence is an offence, punishable by up to six months' imprisonment, a fine, or both. Fines at that level have no upper limit in England and Wales. After a conviction, a court may also cancel any licence held and disqualify the person from holding a licence or from owning or keeping animals.
In Scotland, the penalties are higher. Offences such as breeding without a licence can bring a fine of up to £40,000, up to 12 months in prison, or both. In Wales, selling pets without the required pet vending licence carries up to six months' imprisonment, a fine, or both.
The rules may also tighten. The UK Government's Animal Welfare Strategy, published on 22 December 2025, commits to consulting on dog breeding reform. This includes a possible registration system under which breeders in England who don't currently need a licence would register with a regulator, most likely their council. We'll update this guide when the proposals are published.
FAQs
Do I need a licence for one litter?
Usually not. In England, one litter only needs a licence if you are breeding dogs and advertising a business of selling them, for example, if your pricing, advertising or volume looks commercial. In Scotland, the threshold is three litters, so a single litter is below it.
Do I need a licence if I don't make a profit?
Not under the business test, as a rule. DEFRA's guidance treats breeders who have fewer than three litters a year and sell without making a profit as outside the scope of licensing. The litter test still applies, though. Three or more litters with a sale requires a licence in England whether you profit or not.
Is £1,000 a licensing threshold?
Partly. Under DEFRA's guidance, income below the £1,000 HMRC trading allowance means no licence is needed under the business test. Income above it doesn't automatically make you a business, and the figure never overrides the three-litter rule.
How much does a licence cost?
It depends on your council, the number of dogs, the length of the licence and vet inspection costs. Published 2026/27 fees range from a few hundred pounds to over £600 before vet fees, so ask your council for its current fee schedule.
How many litters before I need a licence?
Three in any 12-month period in England, Wales, Scotland and Northern Ireland. In England, you also need to have sold a puppy for the litter test to apply. In Wales and Northern Ireland, it applies only if you keep three or more breeding dogs.
Do I need a licence to rehome puppies from a rescue?
In England, registered charities rehoming puppies born to rescue dogs are exempt, unless they are in practice running that part of their work as a commercial activity. Scotland licenses animal sanctuaries, rehoming centres and other pet rehoming activities separately.
How long does a licence last?
In England, one to three years depending on your star rating. In Scotland, one to three years at the council's discretion.
Can a licensed breeder sell a puppy under 8 weeks?
No. Unless a vet certifies otherwise for health reasons, puppies must stay with their mother for the first 8 weeks.
