Invisalign

Invisalign is an established option for dentist-provided treatment, offered by many UK practices, and a clinician can use it for a wider range of cases than at-home aligners are planned for. It is not the cheapest route, and the brand matters less than the practice: published fees for the same package can differ by more than £1,000, so compare two or three written quotes.

Price

Invisalign does not publish prices; each practice sets its own fee. Three UK practices that publish Invisalign fees:

Practice	Published fees	What the practice says is included
East Midlands Orthodontics, Nottingham	Lite for upper or lower teeth (one arch) £2,250, both £3,570; Moderate one arch £2,500, both £3,860; full treatment £4,100	Whitening with both-arch plans. Replacement aligners £95.50 each; cancellation fee £300. The same page also has a table headed Spark/Invisalign with different fees, so ask which applies
Roka Dental, Milton Keynes	One arch £2,300; Lite from £2,200; Comprehensive from £3,250	Vivera retainers and home whitening. 50% deposit when booking
Notting Hill Dental Clinic, London	Both arches: Express £1,975; Lite £3,065; Moderate £3,625; Full £3,860	Three Vivera retainers with Lite and above; one refinement with Moderate; unlimited refinements with Full

Checked 26 October 2026. Three practices are a sample, not an average. A survey of 1,609 UK dentists' websites in August 2026 found published starting prices usually between £2,400 and £3,500.

Finance can add a lot. Notting Hill Dental Clinic advertises 0% finance over 12 to 60 months, but its 60-month figure for Full treatment is £77.09 a month, which comes to £4,625.40, or £765.40 more than the cash price (our arithmetic).

Check the APR and the total amount repayable. Adult orthodontic treatment for appearance is rarely available on the NHS. Our cost guide explains what usually sits inside a quote.

Offers and discount codes

We have no verified current offer from Invisalign. That does not mean there is no promotion: we list one only after checking it. The prices in this review are Invisalign's prices without any promotion.

If Invisalign shows a discount or a code when you visit, check its end date and terms on Invisalign's own site before you rely on it, and compare the total you would pay. We list an offer only after checking it on the provider's site and recording its terms, including any end date the provider gives.

How treatment works

Consultation and records. A dentist or orthodontist examines you, checks your teeth and gums are healthy enough to start, and takes a 3D scan and any X-rays needed. Some practices offer a free consultation; others charge.
Plan and preview. The clinician plans the tooth movements in Invisalign's ClinCheck software and can show you a 3D preview. It shows the planned movement, not a guaranteed result. Agree the package, the fee and what it covers before you approve the plan.
Waiting for aligners. Align makes the aligners and sends them to the practice. This wait comes before treatment starts, so ask how long it usually takes.
Fitting. The clinician may bond attachments, small tooth-coloured bumps that help the aligners grip, and may plan IPR, polishing a little enamel between some teeth to make space.
Active treatment. You wear the aligners 20 to 22 hours a day and change them on your clinician's schedule, usually every one to two weeks. Notting Hill Dental Clinic, for example, sees patients every six to eight weeks, and some practices use Invisalign's remote monitoring, where you send photos from your phone between visits. The British Orthodontic Society says aligner treatment often lasts 6 to 24 months.
Refinements and retainers. If teeth fall behind the plan, the clinician rescans and orders more aligners. At the end you move to retainers.

If you lose an aligner or one stops fitting, contact the practice and keep your recent aligners. Do not skip ahead or force a tray that will not fit fully over your teeth. Our guides cover cleaning aligners, whether aligners hurt and what aligners can and cannot fix.

Invisalign packages

UK practices usually price Invisalign by package, based on how many aligners your plan needs:

Package	Aligners, as practices describe it	Typical use
Express (sometimes i7)	Up to 7	Small changes, often to front teeth
Lite	Up to 14	Mild crowding or spacing
Moderate	Up to 20	Moderate crowding or spacing
Comprehensive or Full	No set limit	More complex cases

Most packages can treat one arch or both. The package describes what Align supplies to the practice; your contract with the practice decides what you get. Refinements show the difference: at Notting Hill Dental Clinic, Moderate includes one refinement and Full includes unlimited refinements, while East Midlands Orthodontics prices replacement aligners separately. Ask which package your plan uses, how many refinement rounds your fee covers and what happens if your case needs more aligners than the package allows.

What we like

A dentist or orthodontist supervises treatment
The treating clinician examines you, plans your case and sets your check-ups, which may include remote progress checks.
Suitable for more complex cases
Your clinician can use attachments, IPR and extra aligners where your case needs them.
Widely available
Many UK dentists and orthodontists offer Invisalign, so you can compare quotes.

What to be aware of

Fees vary a lot between practices
Published both-arch fees for the same package differ by hundreds of pounds, and full treatment by more.
Package limits matter
A low Express or Lite price may cover only a short plan; check what happens if you need more aligners.
Check what is included
Retainers, refinements, replacement aligners and finance terms are set by each practice.

Clinical oversight

Your treating dentist or orthodontist is responsible for your care and sets how often you are seen. Invisalign is offered by both general dentists and specialist orthodontists. You can check any clinician on the General Dental Council register, which also shows whether they are on the specialist list for orthodontics. For bite problems, a growing child or a case another dentist has called complex, it is worth seeing a specialist.

Invisalign does not set a minimum age. It makes ranges for teenagers and children, and your clinician decides whether treatment is suitable.

For problems with aligners, appointments or billing, your contact is the practice, not Align. If a complaint about private treatment is not resolved by the practice, the Dental Complaints Service can help.

You will need retainers after treatment to stop your teeth moving back, and your clinician will tell you how long and how often to wear them. Wearing retainers is part of treatment; paying for a retainer plan is a separate choice.

Many practices offer Invisalign's Vivera retainers, usually sold as sets of three. Roka Dental lists a set at £450 and simple clear retainers at £175 per arch, and two of the three practices above include Vivera retainers in their fees. Ask whether retainers are included, how many sets, and what replacements cost.

Invisalign does not offer its own guarantee. Refinements, refunds, cancellation and what happens if you move are set by the practice, so ask for those terms in writing before you pay a deposit.

Alternatives worth comparing

Option	How it differs from Invisalign	Price context
Spark	Ormco's dentist-provided system, often offered by the same practices	East Midlands Orthodontics publishes two fee tables that do not match, so ask for a quote for each system
Angel Aligner	Another dentist-provided system, offered by fewer practices	£1,500 for a small Select plan to £3,500 for Pro at one Ipswich practice
Impress	A clinic chain that provides Invisalign aligners at fixed plan prices, at its own clinics in England	£1,990 to £3,990 for its three adult plans
Smile White	Fixed-price aligners with check, fitting and follow-up visits at a partner dental practice	£995 to £3,695 by plan
Straight Teeth Direct	Home impressions and app-based monitoring; its pages do not describe practice visits	£1,790 for both arches, plus a £69 impression kit
Fixed braces	Work without daily wear discipline; more visible	£5,250 for both arches in metal at East Midlands Orthodontics

If your case is mild and mainly cosmetic, a fixed-price provider may be enough. If you have a bite problem, an in-person system such as Invisalign, Spark or Angel, or fixed braces, is the safer comparison. Our guide to teeth straightening options compares the main approaches.

What the evidence shows

Align says more than 22 million people have been treated with Invisalign, and its comparisons with other aligners and braces come from its own data. Published research on clear aligners often involves Invisalign, but studies differ in the cases treated and the version of the system used, and none of that tells you how well a particular practice will plan and supervise your case.

Online reviews of Invisalign mostly describe practices rather than the aligners, so read reviews of the practice and clinician you are considering. We have not treated patients with Invisalign or surveyed its customers.

Who this may suit

Invisalign suits someone who wants a dentist or orthodontist to examine them, plan treatment and supervise it, particularly with a bite problem or a case at-home aligners will not take on. It also suits people who want the widest choice of practices to compare.

If your case is minor and price matters most, compare a lower-cost provider. If you are offered a short package such as Express or Lite, check it covers enough aligners for your plan.

Questions worth asking before paying

Which Invisalign package is my plan based on, and does the fee cover one arch or both?
How many refinement rounds does my fee cover, and what does another cost?
Are retainers included, how many sets, and what do replacements cost?
What does a lost or broken aligner cost to replace?
Are you on the specialist list for orthodontics, and how often will I be seen in person?
If I use finance, what is the APR and the total amount repayable?

Bottom line

Invisalign is an established option for dentist-provided treatment. Compare the clinician, the package and the written quote, including any further aligners and retainers, because the practice matters more than the brand. Ask which package your plan uses, get refinements, retainers and replacement aligners itemised in writing, and compare two or three quotes, including Spark or Angel if the practice offers them.
