How to start a personal training business in the UK

Before you start

What you need before your first paying client

There is no licence to be a personal trainer in the UK, but gyms, insurers and clients all expect the same few things.

Qualifications: Level 2 and Level 3

The usual route is a Level 2 Certificate in Fitness Instructing (Gym), then a Level 3 Diploma in Personal Training. Many providers sell the two as one course. No law says you must hold them, but almost every gym and insurer asks for a recognised Level 3 before you train clients on your own.

Before you pay, check the course is Ofqual-regulated and endorsed by CIMSPA (the Chartered Institute for the Management of Sport and Physical Activity), the sector's professional body, which keeps a directory of endorsed courses. Once qualified, you can apply for its Personal Trainer Practitioner status, which shows your qualifications have been checked. It is voluntary, and when we checked in October 2026 it cost £38.94 a year including VAT. If a gym asks whether you are "REPs registered", it means CIMSPA: REPs was folded into CIMSPA in 2020.

First aid, and a DBS check if you coach under-18s

Most gyms and many councils ask to see a current first aid certificate. If you plan to train under-18s, expect venues and councils to ask for a DBS check as well.

Insurance

Insurance isn't a legal requirement unless you employ someone, but venues insist on it, and without it any claim lands on you personally. Most trainers need public liability and professional indemnity as a minimum. Our guide to personal trainer insurance in the UK explains each type of cover and what to check, so we won't repeat it here. Sort it before your first session.

Tax and paperwork

How to become a self-employed personal trainer in the UK

Most personal trainers start as sole traders. You trade under your own name or a trading name, keep the profit after expenses and pay Income Tax and National Insurance through Self Assessment.

Registering with HMRC

• When: once your gross income from self-employment is over £1,000 in a tax year (the trading allowance), you need to register for Self Assessment. The deadline is 5 October after the end of the tax year you started in, so a trainer who starts in May 2026 has until 5 October 2027.
• How: online at gov.uk. You will get a Unique Taxpayer Reference (UTR), which you need to file your return.
• Records: keep every invoice and receipt from day one, through a separate bank account. Costs such as insurance, gym rent, kit, courses, software and travel to clients' homes can usually be set against your income.

Making Tax Digital

Making Tax Digital for Income Tax now applies to sole traders with qualifying income over £50,000, and from 6 April 2027 to those over £30,000. It means digital records and quarterly updates through compatible software. Few trainers reach those figures in year one, but bookkeeping software that supports it saves a switch later.

Sole trader or limited company?

A limited company can make sense once profits grow, but it brings more admin, so most trainers start as sole traders and review it later with an accountant. If a gym sets your hours, your prices and how you work, check whether you are self-employed at all. HMRC's employment status tool gives its view.

Where you work

Where to train clients: gyms, homes, parks or online

Where you train decides your costs, how you find clients and what your insurance needs to cover. Plenty of trainers mix two.

Working in a commercial gym

Gyms that host self-employed trainers tend to use one of two models, and some let you choose:

• Rent-free, in exchange for floor hours. You pay little or no rent, but give the gym a set number of unpaid hours a week on the gym floor, helping members and running inductions. Costs stay low while you build a client list, and the floor is where many first clients come from.
• Rent-paying. You pay a monthly fee to train clients there, with fewer or no floor hours. It costs more each month, but gives you your time back once your diary is full.

Rents and hours vary by operator and by site, and gyms rarely publish them, so ask the PT manager for the terms in writing and work out how many sessions a month cover the rent before you agree. Some gyms also offer salaried PT roles, which suit trainers who want steady income while they learn the business side.

Clients' homes and mobile training

Training people at home, at work or in their gardens means no rent, but you carry kit, lose time to travel and fit fewer sessions into a day. Price that in, set a travel radius and check your insurance covers work away from a fixed venue.

Parks and outdoor sessions

Outdoor training is cheap to start, but it isn't always free. Many councils require a permit or licence for commercial fitness sessions in their parks, and the rules differ from one council to the next. Bournemouth, Christchurch and Poole Council, for example, requires a licence for outdoor exercise classes on its parks and beaches, with proof of at least £5 million public liability cover, a risk assessment and a first aid qualification. Ealing requires a permit for commercial sessions of more than five people. Other councils have no scheme. Search for your council's name plus "fitness in parks", or ask the parks team, before you start.

Online coaching

Online coaching removes rent and travel and lets you work with anyone. It also puts you up against coaches everywhere, so it works best once you have a clear niche and some results to show. Check your insurance covers online work, and note that Google doesn't allow a Business Profile for online-only coaching. Our guide on how to get personal training clients covers winning online clients in more detail.

Money

Your prices, packages and personal training business plan

A personal training business plan doesn't need to be a long document. It needs to answer who you help, what you charge and how many sessions you need to sell.

A one-page business plan

• Who you help: be specific. "Strength training for women over 40" or "getting back to fitness after injury" is easier to market than "anyone who wants to get fit".
• Your monthly costs: rent, insurance, software, kit, travel, and money set aside for tax.
• Your target income, and the number of paid sessions a week that gets you there at your prices.
• Where your first clients will come from over the first three months: the gym floor, your own network, referrals, Google and Instagram.

Be honest with the sums. If they only work with a diary fuller than you could keep up week after week, the price or the plan needs to change.

Setting your prices

Look at what five or six trainers near you with similar experience charge, and place yourself sensibly among them rather than at the bottom. Our guide to getting clients includes published UK price ranges per session, and our guide on how much to charge per session walks through working out a rate from your own costs.

Packages that suit you and your clients

• A starter offer: one low-risk first step, such as a consultation or a short block of sessions.
• Session blocks: 10 or 20 sessions paid up front, with an expiry date.
• Monthly packages: a set number of sessions a month on a recurring payment, which gives you steadier income.
• Small group or semi-private training: two to four people sharing a session, cheaper for each of them and better paid per hour for you.

Put at least a starting price on your website. People who have to ask often don't.

Getting set up online

Booking, payments and getting found online

When someone hears about you, they look you up. A simple website, a Google Business Profile and one social account cover most of what a new client checks.

Booking and payments

Let clients book and pay without a back-and-forth over messages. Calendly and Acuity suit a trainer working alone. Fitness platforms such as TeamUp, Glofox and Mindbody add memberships, packs and class bookings, at a higher monthly cost. Whichever you use, take payment when people book or by recurring card payment, and publish a cancellation policy. Our guide on reducing no-shows covers deposits and reminders.

A simple website

Four or five pages is plenty to start: who you help, packages and prices, qualifications and insurance, where you train, client stories shared with permission, and a booking button on every page, all quick to load on a phone. Our page on websites for personal trainers shows what we include.

Google Business Profile

It is free, and it is often what shows up first when someone searches "personal trainer near me". If you train in clients' homes or in parks, set it up as a service-area business: hide your address and list the towns you cover. Choose "Personal trainer" as your main category, add real photos of you working and ask happy clients for reviews. Our guide to Google Business Profile covers set-up step by step.

Instagram

Pick one platform and post two or three times a week, answering the questions clients ask you in sessions. Put your booking link in your bio and reply to messages quickly. Advertising rules apply to your own posts: before and after photos need the client's consent and must be genuine, and you shouldn't promise set results in a set time.

A simple plan

Your first 30 days

Spread this across four weeks alongside your training. You don't need all of it done before you take your first client.

Week one

• Check your Level 3 certificate and first aid are current
• Register as self-employed with HMRC and open a separate bank account
• Buy insurance that names everything you plan to do
• Agree terms with your gym in writing, or check council rules for the parks you want to use

Week two

• Set your prices and one clear starter offer
• Set up booking and payments, with a cancellation policy
• Set up and verify your Google Business Profile
• Buy your domain name and get a simple website live

Week three

• Tell your network who you help and how to book
• Work your floor hours at peak times, or run a free taster session
• Ask your first clients for honest feedback and a Google review
• Publish your first few Instagram posts

Week four

• Compare the sessions you have sold with your plan
• Follow up everyone who enquired but didn't book
• Look at your website on a phone: is booking obvious?
• Set up a simple routine for recording income and expenses each week
