Short answer
Adult Invisalign in London starts from around £2,650 to £2,800, based on one London orthodontic group’s published prices (checked October 2026), with teen aligners from around £2,500 to £2,760. Simple cases needing fewer aligners cost less than complex ones, so check whether the consultation, scans, refinements and retainers are included in any quote.
Invisalign is a brand of clear aligners: a series of thin, removable, custom-made plastic trays, each worn for a week or two, that move the teeth in small planned steps.
Invisalign is one of the most popular ways to straighten teeth in London, and “how much does it cost?” is usually the first question. The honest answer is that it depends on your teeth, the practice and what the quote includes. This guide shows published London prices, explains what changes the fee, and lists the questions that help you compare quotes like for like.

Published Invisalign prices in London
Few London practices publish full aligner price lists. One London orthodontic group lists prices for its central London practice and its outer London branches in Teddington and Richmond. These are “from” prices: straightforward cases sit near the bottom and complex cases higher.
| Treatment | Central London, from | Outer London, from |
|---|---|---|
| Adult Invisalign aligners | £2,650 | £2,800 |
| Child / teen aligners | £2,760 | £2,500 |
| Adult metal braces (for comparison) | £3,650 | £2,800 |
| Adult clear (ceramic) braces (for comparison) | £4,000 | £3,150 |
| Adult consultation with 3D imaging | £145 | £140 |
| Replacement removable retainer | £145 | £110 |
| Upper and lower bonded retainers | £500 | £450 |

Interestingly, at this group adult aligners start slightly cheaper in central London than in outer London, while fixed braces are cheaper in outer London. It is a reminder that you cannot assume one option or one location is always cheaper: compare actual quotes.

Request a consultationWhat affects the cost of Invisalign?
How much your teeth need to move. Minor alignment of a few front teeth needs fewer aligners and fewer appointments than correcting crowding and the bite across both arches. Many providers price aligner treatment in tiers based on complexity.
Refinements. Teeth do not always track exactly as planned, so extra “refinement” aligners are sometimes needed towards the end. Some quotes include refinements for a set period; others charge for them.
Who plans and supervises treatment. Aligners can be provided by specialist orthodontists and by general dentists. A specialist may charge more, but for complex cases their training in diagnosing bite problems can be worth it. Whoever treats you should be on the GDC register.
Retainers. Keeping the result means wearing retainers long term. Ask whether the first set is included and what replacements cost: the group above lists replacement removable retainers at £110–£145.
Location and practice costs. Rents and staff costs vary across London, and so do fees.
What should an Invisalign quote include?
- The total fee for the whole course of treatment, in writing.
- Whether the consultation, 3D scan, X-rays and photos are charged separately.
- How many refinements are included, and for how long.
- Which retainers are included at the end, and the cost of replacements.
- How many check-up appointments are expected and who you will see.
- What happens, and what it costs, if treatment takes longer than planned or you lose an aligner.
Invisalign vs braces: which costs less?
For straightforward cases, aligners can cost about the same as, or less than, fixed braces, as the published prices above show. For complex cases, fixed braces are often more efficient and aligners may not be suitable at all. The cheapest option is the one that actually achieves the result you want without extra rounds of treatment, which is why an examination matters more than a headline price. Our braces cost guide covers fixed appliances in detail.
Paying monthly
Many London practices let you pay a deposit and spread the rest over the treatment, and some offer interest-free credit through a lender, subject to status. Finance is arranged by the practice, not by us. Look at the total amount payable and whether the agreement is regulated credit.
A word on remote aligner kits
Direct-to-consumer aligner kits with little or no in-person supervision can look cheaper. Professional bodies recommend an in-person examination before any orthodontic treatment, because moving teeth with undiagnosed gum disease or decay can cause lasting damage. Whatever you choose, make sure a GDC-registered clinician has examined you and is overseeing treatment.
