How to start a private therapy practice (and what it really costs)

Most guides to opening a private practice list the things you need to buy and then go quiet the moment you ask what any of it costs. You are left with a checklist and no budget.

So let's put numbers on it. Below is what it actually takes to start and run a private therapy practice, what to charge once you open the doors, what a practice realistically earns, and the quiet leaks that decide whether the maths works.

What it costs to start a private therapy practice

Starting lean, working from telehealth or a part-time room, most therapists can open for roughly 1,000 to 3,000 pounds. The biggest variable is whether you rent a fixed consulting room from day one or start virtual and add space later. Here is where the money goes.

These are ranges, not quotes. The point is the order of magnitude: opening a private therapy practice is one of the cheaper businesses to start, because your main asset is a qualification you already hold. The trap is not the startup bill. It is the running cost and the revenue you let slip once you are open.

The startup steps, in order

If you are at the planning stage, the sequence matters as much as the spend. Work through it in this order so nothing blocks the next thing.

1. Confirm your qualification and accreditation route, and the supervised-practice you still need to log.
2. Register as a business and sort your data protection registration before you hold any client records.
3. Choose a business structure (sole trader to start is fine for most) and a separate business bank account.
4. Pick GDPR-compliant practice software and sign the data agreement before you take a single client.
5. Set your session fee against your local private-pay market (more on that below).
6. Set up telehealth, or secure a room or sessional space if you are seeing people in person.
7. Build a converting directory profile (Psychology Today and, in the UK and Ireland, Counselling Directory) and a simple website.

Notice what is missing from every checklist like this one: how you actually answer the phone when a prospect calls. We will come back to that, because it is the step that quietly undoes the rest.

Monthly running costs once you are open

The startup bill is a one-off. The running cost is forever, and it is what your fee has to cover before you earn a penny. A solo practice typically carries:

• Practice software subscription, billed monthly per clinician.
• Room rent, if you are not on telehealth. This is usually the single largest line.
• Professional liability insurance, spread over the year.
• Directory listings (Psychology Today, Counselling Directory) on annual or monthly plans.
• Card-processing fees, a small percentage of every session you take payment for.
• Your own clinical supervision and continuing professional development, which never stops.

For a lean telehealth practice the monthly figure can sit in the low hundreds of pounds. Add a consulting room and it climbs fast. Either way, your session fee has to clear all of it before it becomes income, which is exactly why the fee is not a number to guess at.

What to charge per session

Set your fee against your local private-pay market, not against what an insurer or the NHS would reimburse. Reimbursement rates are a floor designed to move volume, not a signal of what your time is worth.

Find the going private rate for your modality and area, then position yourself at or slightly above the middle once you are qualified and have a clear niche. Private-pay rates run higher than panel work because you carry less admin and nobody takes a cut on the way through.

The trade-off is real. Insurance or panel work brings volume with more paperwork and a lower rate; private-pay brings a higher rate and less admin, but you have to generate your own demand. Most thriving solo practices lean private-pay and treat demand generation, not discounting, as the job.

What a private practice actually earns

Here is the maths the salary articles never finish. Owner take-home is caseload times session fee, minus your running costs, minus leakage.

On paper it looks generous. A full week of private-pay sessions at a solid fee, week after week, gets a busy solo therapist a long way up the income ladder. The reason the bank balance rarely matches the spreadsheet is the part nobody itemises: the gap between the sessions you could bill and the sessions you actually bill.

That gap has two causes, and both are fixable.

The leaks that erode it: no-shows and missed calls

A no-show is a paid hour gone with no way to get it back. A solid cancellation policy and an automated reminder recover most of those. But the bigger, quieter leak is the one upstream of any client ever booking.

When you are in a fifty-minute session, your phone is on silent. A prospective client who has finally worked up the nerve to call gets voicemail. Most of them do not leave a message. They go back to the directory and call the next therapist who picks up, and that client, and every session they would ever have booked, becomes someone else's income.

You cannot answer mid-session, and you should not try. But the call does not have to go to voicemail. An answering service built for this can take the enquiry, capture what the caller needs, and book or pass it to you, so the phone ringing while you work stops costing you clients.

The full playbook for filling a caseload is its own job, and we cover the channels that actually work in how to get more therapy clients. The software that schedules, notes and bills those clients is covered in our rundown of the best practice management software for therapists.

Run your own numbers

The figures above are a starting frame, not your business plan. Your insurance, your room, your fee and your market will move them. What does not change is the shape: a modest startup bill, a fixed monthly cost your fee has to clear, and a take-home that lives or dies on how few sessions leak away.

Spend an hour costing your own version before you open. Then protect the income end as hard as you planned the startup end, because a full diary is worth far more than a cheap one.
