How much does Invisalign cost in the UK? (2026 price guide)

Invisalign in the UK typically costs £1,500–£5,500, and the reason for that huge range is simple: how much your teeth need to move. Minor tweaks sit at the low end; a full smile transformation sits at the top. Here’s exactly what changes the price, and how to avoid overpaying.

First, the current national picture from clinics on TreatmentCosts:

So, what does Invisalign cost?

Most people pay £2,500–£4,500 for a typical Invisalign case. Small, front-teeth-only corrections can be £1,500–£2,500, while complex cases that move most of your teeth can reach £5,000+. The clinic, your city and the dentist’s experience all play a part too.

Good news: almost every clinic offers 0% finance, so the headline figure is usually spread over monthly payments rather than paid upfront.

Why the price varies so much

Invisalign comes in different “packages” based on how many aligners you need:

• Express / Lite / i7 (minor cases): fewer aligners, faster, cheaper — ~£1,500–£2,800.
• Comprehensive / Full (most cases): unlimited aligners for bigger movements — ~£3,000–£5,500.

So when you compare quotes, check which package you’ve been quoted for — a cheap headline price might be for a “lite” plan that won’t cover your case.

What’s included

• Consultation and 3D scan (sometimes a separate fee).
• All your aligners for the treatment.
• Check-ups throughout.
• “Refinements” — extra aligners to perfect the result (check this is included).
• Retainers at the end — sometimes included, sometimes extra (£100–£300).

The two things people forget to ask about are refinements and retainers — make sure both are in your quote.

What changes the price

• Case complexity — the single biggest factor.
• Package type (Lite vs Comprehensive).
• Location and clinic — central London skews higher.
• Whether retainers and refinements are included.
• The dentist’s Invisalign experience (Platinum/Diamond providers may charge more).

Does where you live change the price?

Yes — sometimes by over a thousand pounds for the same treatment. Here’s how Invisalign prices currently compare across the cities we track:

Is it cheaper on the NHS?

For adults, Invisalign isn’t available on the NHS — clear aligners are considered cosmetic. NHS orthodontics is generally limited to under-18s with a clinical need, and uses traditional metal braces, not clear aligners. So for nearly everyone, Invisalign is a private treatment. The trade-off you’re paying for is a near-invisible, removable alternative to braces.

Invisalign vs the alternatives

• At-home / mail-order aligners are cheaper but have no in-person dentist supervising — riskier, and not suitable for many cases. Be cautious.
• Fixed braces can be cheaper and better for complex cases, just more visible.
• If your main concern is small gaps or chips rather than alignment, composite bonding or veneers might be a faster, cheaper route.

Many people also whiten their teeth at the end of Invisalign for a complete finish.

How to avoid overpaying

• Confirm the package — and that it covers your full case.
• Check refinements and retainers are included.
• Ask about 0% finance and the total repayable.
• Compare a few experienced providers — prices vary widely.
• Look just outside the city centre for the same treatment at lower cost.
