Costs & Charges
How much does Invisalign cost in the UK?
By The Local Dentist Editorial · Updated 13 July 2026
What drives the price
Clear aligner pricing is driven by complexity: how far your teeth need to move, whether one or both arches are treated, and how long treatment takes. A short 'express' course straightening mildly crowded front teeth sits near £1,500–2,500; comprehensive treatment correcting crowding and bite issues across both arches over a year or more runs towards £4,000–5,500. Practices also differ in what the headline price includes, so two quotes for the same teeth can hide very different totals. The dentist's fee reflects their time across every review appointment, not just the aligners themselves — aligner treatment is a course of supervised dentistry, not a product purchase.
What a fair quote should include
Before comparing prices, confirm what is bundled. A complete quote covers the initial assessment and 3D scans; the full series of aligners; 'refinements' (extra aligners if teeth have not moved exactly to plan, which is common); any attachments or interproximal reduction; and retainers at the end — because without retainers, teeth drift back and the money is wasted. Whitening is sometimes bundled as a promotion. Ask specifically whether refinements and retainers are included or charged extra; they are the two most common hidden costs. Get the answer in a written treatment plan, which any reputable practice provides as standard.
Invisalign vs NHS braces and other aligner brands
The NHS funds orthodontics only for under-18s who meet the clinical-need threshold (assessed using the IOTN index), and NHS treatment uses fixed braces, not clear aligners — adults rarely qualify for NHS orthodontics at all. So for most adults the realistic comparison is between aligner brands and fixed braces privately. Invisalign is the best-known aligner brand, but dentists offer several systems, and fixed braces remain the benchmark for complex movement. At-home aligner companies advertise lower prices, but remote-only treatment involves less clinical supervision — see our separate answer on whether at-home aligners are safe before deciding on price alone.
Spreading the cost
Most practices offering Invisalign provide payment options: 0% finance over 12–24 months is common, and longer interest-bearing terms exist for larger cases. Compare the total payable, not the monthly figure — a low monthly payment over a long interest-bearing term can add meaningfully to the cost. A deposit followed by 0% instalments across the treatment period is usually the cleanest structure. When comparing practices on our listings, look at the quoted range, what it includes, the clinician's experience with aligner cases, and reviews, rather than the lowest headline number. An in-person consultation (often free) is the only way to get a price for your actual teeth.
People Also Ask
Can I get Invisalign on the NHS?
No. NHS orthodontics is limited to under-18s with a qualifying clinical need and uses fixed braces. Clear aligners such as Invisalign are always private treatment.
Why did I get quoted different prices by two dentists?
Aligner treatment is private, so each practice sets its own fees, and quotes may bundle different things — refinements, retainers, whitening. Compare itemised treatment plans, not headline prices.
Are retainers included in the price?
Not always — and you will need them, because teeth drift back without retention. Ask whether retainers (and replacement retainers) are included before you sign anything.
Is cheaper at-home aligner treatment the same thing?
No. At-home aligner companies cut cost by cutting in-person supervision. Aligner treatment must still be prescribed by a GDC registrant, and remote-only care suits a narrower range of simple cases. Speak to a dentist about whether your case is suitable.
