You've qualified. Here's how to start.

You can start trading this week. Nothing in UK law requires a licence or a qualification to groom a dog. What you need before the first paid dog is insurance, a price list you can defend, three policies written down, and somewhere to record every dog you touch. The rest, HMRC included, has deadlines months away.

This page is long because the first year is where grooming businesses are won or lost, and most of the advice new groomers get is either a sales pitch or a list of platitudes. Every number below is from a UK source you can click, checked in October 2026. Where the evidence is a vendor's own data, it says so.

1. The legal bits, in the order they bite

There is less of this than people fear. One thing has to happen before the first dog, one within a few weeks, and the rest has a deadline a year away.

Insurance, before anything else

You need public liability (most policies give £5 million) and, separately, care, custody and control cover, which pays out if a dog in your care is injured, lost or dies. Generic business policies often leave that out. Add cover for your kit if it leaves the house, and employers' liability the day you take on anyone, even part time; that one is a legal requirement. In October 2026 Cliverton quoted from £135.05 a year, Protectivity from £5.41 a month, Pet Business Insurance from £6.81 a month and Simply Business from £5.05 a month. If you groom from a van, none of those covers the van; it needs a commercial vehicle policy of its own. One insurer excludes XL Bullies, so read the exclusions before you take a booking.

HMRC, with a deadline a year away

You are a sole trader the day you take money. Once your trading income in a tax year passes £1,000, you must register for Self Assessment by 5 October after that tax year ends. Start in November 2026 and the tax year ends on 5 April 2027, so the deadline is 5 October 2027, and the first tax is due 31 January 2028. Register in the first month anyway: it is a ten-minute form, and it stops the deadline being a thing you forget. There is no legal need for a separate business bank account, but most personal accounts forbid business use in their terms, so open one. If your turnover passes £50,000, Making Tax Digital applies from April 2026; over £30,000 from April 2027. The MTD guide covers it.

The data protection fee most groomers don't know about

If you keep client records, which you will, you owe the ICO a data protection fee. It applies to sole traders. Tier 1 is £52 a year, or £47 by direct debit, for anyone with turnover under £632,000. The ICO has a short self-assessment to confirm it, and a groomer holding names, phone numbers and dog records in an app or a spreadsheet is very unlikely to be exempt.

Licensing, and where it is heading

Grooming is not on the list of licensable activities in England's 2018 Regulations or Scotland's 2021 Regulations, and councils say so plainly on their websites. The Animal Welfare Act 2006 still applies to every dog on your table, and the sector's own Guidelines for Dog and Cat Groomers, published by the Pet Industry Federation and the Canine and Feline Sector Group in June 2025, are what a council would measure you against if anyone complained. Scotland consulted on licensing groomers in 2023, and 82% of responses supported it. Wales said in June 2025 that grooming is in its next phase of regulation. Nothing has changed yet, but it will, and the groomer with a record of every dog, every consent and every incident will not notice.

Working from home

The planning test is whether your home stops being mainly a home. Grooming one dog at a time in a converted garage with no sign and no staff is often fine. Clients' cars in a cul-de-sac, a high-velocity dryer running at 95 to 108 decibels with the window open, and a sign at the gate are what tip councils into asking for a change of use application. Where permission is granted it usually comes with conditions: hours like 9 to 6, Monday to Saturday, and a cap such as ten dogs a week. Ask your council's planning team by email before you spend on kit, and keep the reply.

Working from a van

Conversions carry 150 to 250 litres of fresh water. The wash water can only go to a foul sewer, never a surface drain or a gully in the road; several water companies publish a pet grooming position statement that treats it as low risk provided there are no solids and no excess hair. Check yours. Park where a generator at 50 to 60 decibels for two hours won't start a complaint, and keep the van policy separate from the grooming policy.

Qualifications and the register

None is required by law. The Level 3 Diploma is the bar the trade recognises: City & Guilds 7863-03, iPET Network, OCN West Midlands, AIM, SEG Awards or ICMG. It is also the entry requirement for The Groomers Spotlight register, which lists qualified groomers for owners to find and costs £90 a year. Pet Industry Federation membership starts at £194 plus VAT a year and hosts the British Dog Groomers' Association. Neither is essential in month one. Both are worth it once the first fifty clients are in.

2. Kit: what to buy, and what to leave until year two

Prices below are from UK grooming retailers in October 2026. The two things to spend on are the table and the dryer, because they are what your back and your wrists will feel every day. Scissors come second. The expensive bath can wait.

Bought carefully, a home salon runs £1,500 to £4,000 in kit. Tuft's 2026 guide puts the range at £2,400 to £6,800 and we don't disagree if you buy new and buy the good bath. A mobile conversion is £8,000 to £15,000 on top of the van: Wet Pets quoted £7,995 plus VAT for a full package with a 250 litre tank and £14,495 plus VAT for one that needs no generator; Pro Dog Baths £12,750 to £14,900 including VAT. A used Boxer or Sprinter adds £10,000 to £12,000. Table rental in someone else's salon, at £50 to £200 a week, is how a lot of groomers start without any of it.

3. Price from data, not from the groomer down the road

Two UK datasets published in 2026 give real prices. Tuft averaged 15,029 bookings on its platform from January and February 2026. GroomSlot took 483 listed service prices from its groomers in September 2026. They differ by method and they land close.

London and the South East run 15% to 40% above those figures. Mobile grooming charges £5 to £25 more than a salon for the same dog. Both sources are Tuft's price page and GroomSlot's, and both are vendors' own data, which is still better than a guess.

Work backwards from the income you need rather than forwards from what feels polite. Four dogs a day, four and a half days a week, forty-six weeks a year is 828 grooms. At £50 that is £41,400 before costs. At £42, because you matched the salon on the high street, it is £34,776. The £6,600 difference is the price of copying someone else's list. Two rules that every experienced groomer gives new ones: put a matting charge on the list before anyone asks for it, and raise your prices every year.

4. Three policies to write down before the first booking

Not a terms-and-conditions document. Three short paragraphs, on your booking page and in your confirmation email, that you will be glad of within a month.

1. A deposit and cancellation policy. A deposit at booking, 48 hours' notice to cancel, the deposit kept on a no-show and 50% charged for a late cancellation is the pattern UK salons use. A no-show costs a mobile groomer the groom and the diesel.
2. A matting policy. Say that matted coats cost more and are charged by time, that you will de-mat for no more than 15 to 20 minutes, and that past that you clip the coat off, because the Animal Welfare Act 2006 puts the dog's comfort above the owner's preference. Owners agree when it is written down and argue when it isn't.
3. A consent form. Permission to get veterinary treatment in an emergency at the owner's cost, and permission to use photos. Collect it once per client rather than once per groom.

Whatever system you book with should record that the client accepted these, with the time and the booking. If it doesn't, keep a signed copy. GroomRules logs acceptance on every booking.

5. The first fifty clients

Fifty clients on a six-week cycle is eight or nine grooms a week, which is a part-time living and a full diary within a year once they tell their friends. Everything UK groomers report working in the first six months is local and free.

• Set up a Google Business Profile with your real address or service area, hours, prices and photos, and ask every happy client for a review the day after. "Dog groomer near me" is how most owners search.
• Post before-and-after photos, with the owner's permission, in your town's Facebook groups and on Instagram. Groomers who sell say the same thing: nothing persuades like a photo of a dog someone recognises.
• Walk in to every vet, pet shop, dog walker and puppy class within ten minutes of you, with cards. They see your ideal clients every day and are asked for recommendations constantly.
• Offer discounted first grooms, not free ones, in exchange for a photo and a review. Free attracts the wrong people and sets the wrong price.
• Give both sides £5 off when a client refers a friend.
• Book the first ten dogs from people you know, at full price or close to it, and treat them as the dress rehearsal for your timings.

Then let the recalls do the compounding. A dog that comes back every four to eight weeks is worth six to twelve grooms a year. Reminding owners when the dog is due, by text and email, is the single habit that turns fifty clients into a full diary. Most groomers do it from memory; GroomRules does it for you.

6. The mistakes that end first years

• Copying the nearest salon's prices. GroomSlot's line is right: "fully booked but exhausted and underpaid".
• Taking every dog. An aggressive dog, a severely matted dog or a breed your insurer excludes is a no, politely.
• No deposit, so a Saturday morning no-show costs £100 and there is nothing to say.
• No matting policy, so the argument happens at the door with the dog on the table.
• No records. Which dog bit, which owner is late, what blade you used last time, when the vaccinations lapse.
• Too many dogs a day. The 2025 to 2026 global groomer health study found 84% of groomers in joint or muscle pain and 79% with back pain. Cap your day at four or five from the start, set the table to your height and take the break.
• Grooming before the insurance is in place, or after it has lapsed.
• Forgetting HMRC until the letter arrives.
• Never raising prices, because the first clients were friends.

7. A thirty-day start

1. In week one, buy the insurance, pay the ICO fee, register with HMRC, email the council's planning team if you are at home, open the bank account and write the three policies.
2. In week two, buy the table, dryer, clippers, four blades, scissors, brushes and two muzzles. Set the price list from the table above and your own sums. Set up the booking system with your services, hours, breed rules and policies, so that every booking from here on is recorded.
3. In week three, get the Google Business Profile live, and the Instagram and Facebook pages with the first photos from friends' dogs. Take cards to every vet, pet shop, walker and puppy class within ten minutes of you.
4. In week four, take the first paid dogs, booked through your link so the breed, coat and last groom are on record. Ask each owner for a review. Set the recall interval for every dog as it leaves.

Where GroomRules fits

A new groomer needs records from the first dog, a booking page that asks about the dog so the first bookings are the right length, policies logged against every booking, and recalls so the first fifty clients come back without being chased. That is what GroomRules does, and the Free plan does it for nothing until you have 100 clients, without texts. Starter, at £29 a month, adds 200 texts, recalls by text and the income-by-quarter export for HMRC, and the first 30 days are free with no card.

It does not take deposits or card on file yet, so your deposit policy runs through bank transfer for now. It is not a marketplace, so it will not send you strangers; the list above is how you find them.
