How Much Does Invisalign Cost in the UK? (2026 Prices)
Last updated 29 September 2026
Invisalign is priced as a whole course of clear aligners, and the price depends mostly on how many aligners your teeth need. Practices sell it in tiers, from short courses for small corrections to full treatment for more complex cases.
Quick answer: full Invisalign typically costs £3,950, and most practices charge £3,525 to £4,248. Shorter courses for minor straightening, sold as Invisalign Lite, Express, i7 or Go, typically cost £2,750. Across all 127 practices that publish an Invisalign price, starting prices begin at £999.
Invisalign prices by treatment type
| Treatment | What it's for | Practices with a price | Typical price | Most practices charge |
|---|---|---|---|---|
| Invisalign Express, i7, Go or Lite | Small gaps, crowding or relapse after braces | 30 | £2,750 | £1,999 to £3,324 |
| Full Invisalign (comprehensive or moderate) | More complex straightening or bite correction | 37 | £3,950 | £3,525 to £4,248 |
Practices name their tiers differently. Express and i7 courses usually use about 7 aligners, Lite up to about 14, and full treatment more than that. Ask how many aligners and refinements your price includes.

What actually drives the price difference
- How many aligners you need. This is the main factor, which is why short courses cost much less than full treatment.
- One arch or both. Some prices cover only the top or bottom teeth. Check before you compare.
- Refinements. Extra aligners to fine-tune the result are included at some practices and charged at others.
- Retainers. You need retainers afterwards to stop your teeth moving back. Some prices include them, many don't.
- Who treats you. A specialist orthodontist may charge more than a general dentist offering Invisalign.
Is Invisalign more expensive than braces?
Often it's similar. Full Invisalign typically costs £3,950, while across the practices on Keystone that list braces or aligners, most charge £2,000 to £3,499. Our braces cost guide has more on fixed braces. For small corrections, a short Invisalign course can cost less than a full course of braces.
Can you get Invisalign on the NHS?
Rarely. The NHS provides orthodontic treatment mainly for under-18s with a clear clinical need, and it normally uses fixed braces. Adults straightening their teeth for cosmetic reasons pay privately.
