Invisalign in London costs £1,800–£5,500 in 2026, depending on case complexity. Invisalign Lite (mild crowding, 14 aligners or fewer) starts at £1,800–£2,800. Moderate cases sit at £3,000–£4,000. Comprehensive treatment for full-mouth correction is £4,200–£5,500 at most established private clinics.
Align Technology offers four tiers of Invisalign, each suited to a different level of crowding or bite issue.

|---|---|---|---|
| Invisalign Express / i7 | Up to 7 | 3–4 months | £1,800–£2,400 |
| Invisalign Lite | Up to 14 | 4–7 months | £2,500–£3,200 |
| Invisalign Moderate | Up to 20 | 7–10 months | £3,200–£4,000 |
| Invisalign Comprehensive | Unlimited | 10–24 months | £4,200–£5,500 |
| Invisalign First (children 6–10) | Phased | 12–18 months | £3,500–£4,500 |
Pure Smiles cases sit at the mid-market end of this range. For a deep comparison between packages, see our Invisalign Lite vs Comprehensive guide.
A complete Invisalign quote is all-inclusive of the digital plan, every aligner set, attachments, IPR (gentle filing between teeth to create space) and retainers. A complete Invisalign quote is not just the aligners — anyone advertising headline prices below £1,500 has usually excluded retainers, refinements or follow-up visits.
At Pure Smiles, the quoted price includes:
According to the British Orthodontic Society, retainers are mandatory after orthodontic treatment — anyone not including them is hiding £300–£600 of cost.
These extras commonly appear after treatment starts and aren’t always in the headline quote:
See our composite bonding vs veneers guide for finishing options.

Online aligner companies advertise £1,200–£1,800 packages without in-person dental supervision. The price difference reflects what’s missing:
According to the British Orthodontic Society and the General Dental Council, unsupervised aligner therapy has been associated with cases of root resorption, bite collapse and gum recession. The GDC issued formal guidance in 2024 reminding clinicians that remote orthodontics must include in-person clinical assessment.
Invisalign is a clinician-prescribed medical device. Online aligners are not held to the same supervisory standard.
