Yes. Physiotherapy is the NICE-recommended first-line treatment for most musculoskeletal problems and typically resolves common conditions in 4 to 6 sessions.
You're considering booking a physiotherapist but you have three honest worries: will it actually work, what will it cost, and what on earth are you supposed to wear. This post answers all three, plus what happens in a session, how many you'll need, and whether it's going to hurt. At SMARTPHYSIO, our lead physiotherapist Sammy is HCPC-registered with over 30 years of clinical experience, and we run physiotherapy in London from clinics in Hampstead, Highgate, the City and the West End, plus home visits across North and Central London.
Does physiotherapy work?
Yes. Physiotherapy is clinically proven to help most musculoskeletal pain, post-surgical recovery and many neurological conditions, usually within 4 to 6 sessions for common problems.
The evidence is strongest where most patients sit: low back pain, sciatica, neck pain, knee and hip osteoarthritis, frozen shoulder, tennis elbow, and rehabilitation after surgery or injury. The NICE guideline on low back pain and sciatica (NG59) lists exercise programmes and manual therapy as first-line treatment for both. The NICE guideline on osteoarthritis (NG226, updated 2022) names therapeutic exercise as the core treatment for hip and knee OA, not pills, not imaging, not surgery. The Chartered Society of Physiotherapy, the UK professional body, holds the same position.
In our clinic, the most common outcome for a new patient with mechanical back pain, sciatica, or a stiff shoulder is meaningful improvement inside three sessions and full resolution inside six. Chronic or post-surgical cases take longer, but the trajectory is the same.
What is physiotherapy?
Physiotherapy is the assessment and hands-on treatment of movement, pain and function by an HCPC-registered clinician, using manual therapy, exercise and education.
It splits into recognisable sub-specialisms. Musculoskeletal physiotherapy treats joints, muscles, tendons and nerves, and covers everything from back pain to sports injuries. Neurological physiotherapy works with the after-effects of stroke, Parkinson's, MS and brain injury. Women's health physiotherapy treats pelvic floor and post-natal problems. Sports physiotherapy sits inside the musculoskeletal field but with a focus on returning athletes to performance.
Two things define a physiotherapist legally in the UK: a degree-level training in physiotherapy, and registration with the Health and Care Professions Council. "HCPC-registered" is the credential to look for. It's the difference between a regulated clinician and someone calling themselves a physical therapist with no protected title.
How does physiotherapy actually work in a session?
Your physio assesses your movement, identifies the cause of the problem, then uses manual therapy and a tailored exercise plan to restore pain-free function.
A first appointment runs in five stages.
First, a clinical history: when the pain started, what makes it worse, what makes it better, what you've tried, and any relevant medical background.
Second, a movement assessment: the physio watches you move, tests your range and strength, and runs specific clinical tests to identify the structure that's actually generating your pain.
Third, a working diagnosis explained back to you in plain English.
Fourth, hands-on treatment to settle the immediate problem, which may include joint mobilisation, soft-tissue work, taping, or pain management techniques.
Fifth, two or three exercises to do at home, and a clear plan for follow-up.
Follow-ups are shorter, reassess progress, and progressively load you back to full function.
What should you wear to a physiotherapy appointment?
Wear loose, comfortable clothing that lets the physio see and move the area being treated. Shorts work for legs or knees, a vest for shoulders or back.
A simple guide by area:
Lower back, hip, knee or ankle: shorts and a t-shirt.
Neck, shoulder or upper back: a vest top or strappy top for women, shorts and a t-shirt you can take off for men.
Foot or ankle alone: anything you can roll up easily.
Whole-body assessment or sports injury: gym kit you'd train in.
You don't need to bring anything special. Clinics have gowns or shorts available if you've come straight from work. Avoid skinny jeans, tights, or anything you can't roll up past the knee.
How much does physiotherapy cost in London?
A private physiotherapy session in London typically costs £70 to £120 for an initial appointment and £60 to £100 for follow-ups, depending on clinic and session length.
Prices vary by location (central London charges more than zone 3), by session length (30 versus 45 versus 60 minutes), and by the practitioner's specialism. At SMARTPHYSIO our clinic appointments sit within that London range, with the initial assessment slightly longer than follow-ups to give us time to do a thorough history and movement screen. Home visits cost more because the physio travels to you and brings portable equipment, and they're worth it when getting to a clinic isn't realistic. You can book a clinic appointment online, or enquire about home visit physiotherapy anywhere across North and Central London.
Most private health insurance policies cover physiotherapy. You don't need a GP referral to self-fund.
How many sessions of physiotherapy will you need?
Most people need 4 to 6 sessions for common musculoskeletal problems. Complex or chronic cases may need 8 to 12. You'll get a re-assessment after the first 3.
A rule of thumb we use:
Acute, recent problems (a sprained ankle, a tweaked back, a stiff neck after sleeping awkwardly): often 2 to 4 sessions.
Sub-acute or moderate problems (sciatica, frozen shoulder in its early stages, tennis elbow): 4 to 8 sessions.
Chronic or complex (long-standing back pain, post-surgical rehab, neurological conditions): 8 to 12 sessions, sometimes more, often spaced out over several months.
If you're not noticeably better in three sessions, that's a signal for the physio to reassess, not for you to keep paying for more of the same.
Is physiotherapy painful?
Physiotherapy shouldn't be sharply painful. Some techniques cause short-term discomfort, and exercises may produce muscle soreness, but anything beyond that means stop and tell your physio.
Three honest distinctions are worth knowing. Treatment discomfort, where a mobilisation or release on a tight area feels uncomfortable in the moment but eases within seconds, is normal. Post-treatment soreness for 24 to 48 hours after deep work or a new exercise programme is normal, much like the soreness from a hard gym session. Sharp, electric or worsening pain during treatment is not normal, and a good clinician will adjust immediately when you say so. You are always allowed to say stop.
What are the benefits of physiotherapy beyond pain relief?
The headline benefit is pain relief, but the bigger gains are usually elsewhere.
Restored function. Getting back to running, lifting your toddler, sleeping through the night, or sitting through a meeting without shifting.
Prevention. Identifying the movement habit, weak link or load mismatch that caused the problem so it doesn't return in six months.
Surgery avoidance or better recovery. For many back, knee and shoulder problems, conservative care resolves the issue without surgery. Where surgery is needed, pre-operative physiotherapy ("prehab") and structured post-op rehab measurably improve outcomes.
Physiotherapy in Hampstead, Highgate, the City, the West End, or at home
We run physiotherapy in London from four clinics: Hampstead and Highgate for North London, the City and the West End for Central London. All four are walkable from a Tube station and bookable online with same-week availability for most appointments.
For patients who can't easily travel, whether that's because of acute pain, recent surgery, an elderly relative at home, or a frail recovery, we offer home visit physiotherapy across North and Central London. Your physio brings everything needed, assesses you in your own environment, and leaves you with a tailored exercise plan you can follow between visits.
Book a physiotherapy appointment
If something has been hurting for more than two weeks, or you're recovering from surgery and want to make sure you do it properly, book in. Most patients leave the first session with a clear diagnosis, immediate hands-on treatment, and a plan for getting back to normal.
Book a clinic appointment at Hampstead, Highgate, the City or the West End, or enquire about a home visit anywhere in North or Central London.

Frequently asked questions
Can I refer myself for physiotherapy?
Yes. You don't need a GP referral to see a private physiotherapist. You can book directly online or by phone. For NHS physiotherapy, most regions now offer self-referral too, though waiting lists are typically 8 to 18 weeks.
How long does a physiotherapy session last?
A first appointment usually lasts 45 to 60 minutes to allow for a full history and assessment. Follow-up sessions typically run 30 to 45 minutes.
Do I need a GP referral for private physiotherapy?
No. Private physiotherapy is self-referral in the UK. Some health insurers ask for a GP letter before they'll fund treatment, so check your policy.
What's the difference between physiotherapy and chiropractic?
Physiotherapists treat the whole musculoskeletal and neurological system using manual therapy, exercise prescription and education, and are HCPC-registered. Chiropractors focus primarily on spinal manipulation. Evidence for physiotherapy across most conditions is broader, which is why NICE recommends it as first-line treatment for back pain, sciatica and osteoarthritis.
Will I get exercises to do at home?
Yes. Almost every physiotherapy plan includes 2 to 4 exercises to do between sessions. Doing them is the single biggest predictor of how quickly you recover.
Is physiotherapy covered by health insurance?
Most UK private health insurers cover physiotherapy, including Bupa, AXA, Vitality, WPA and Aviva. Check whether your policy needs pre-authorisation or a GP referral, and confirm the number of sessions covered.
