If you are researching Invisalign in London, the price is almost certainly one of your first questions. Invisalign cost varies considerably depending on the complexity of your case, the number of aligners needed, and the practice you attend. At Fitzroy Dental Practice in Fitzrovia, we believe patients deserve clear, specific pricing information rather than vague ranges designed to get them through the door. This guide breaks down what you can realistically expect to pay, what drives the differences, and what to look for when choosing a provider.
How much does Invisalign cost in London in 2026?
Invisalign treatment at a quality London dental practice typically falls into the following price brackets depending on case complexity:
- Invisalign i7 (up to 7 aligners, very minor corrections only): typically £1,200 to £1,800
- Invisalign Lite (up to 14 aligners, mild crowding or spacing): typically £2,000 to £2,800
- Invisalign Moderate (up to 26 aligners): typically £2,800 to £3,800
- Invisalign Comprehensive (unlimited aligners, full treatment): typically £3,500 to £6,000
These figures reflect central London private practices. Fitzroy Dental Practice provides a written treatment plan with a fixed fee following your assessment, so you know the full cost before you commit. Retainers, which are needed after treatment to maintain your result, are typically charged separately.
What is Invisalign i7 and is it suitable for minor corrections?
Invisalign i7 is a short-course aligner package designed specifically for very mild tooth movements, typically using seven aligners or fewer per arch. It suits patients with minor relapse after previous orthodontic treatment, small gaps, or very slight crowding limited to the front teeth. It is not appropriate for patients with significant crowding, bite discrepancies, or misalignment beyond the front six to eight teeth. Your dentist assesses suitability using a clinical examination and iTero digital scan before recommending which package applies to your case.
Does Invisalign cost more at a central London practice than elsewhere in the UK?
Generally, yes. Central London practices carry higher overheads than those in other cities or outer London, and this is reflected in treatment fees. Patients in Manchester, Birmingham, or Leeds may find Invisalign priced £300 to £800 lower for equivalent treatment. That said, the quality of the treating dentist, the frequency of review appointments, and the level of clinical support during treatment matter considerably more than geography for achieving the result you want.
What factors affect how much Invisalign costs?
The most significant driver of Invisalign cost is case complexity, which determines which treatment package applies. Beyond that, several other factors influence the total fee:
- Number of aligners: more complex movements require more aligners and more clinical oversight
- Whether refinements are included: some cases need additional aligner series after the initial treatment to achieve the planned result. Comprehensive packages include refinements; shorter packages may not
- Retainers: fixed or removable retainers are essential after treatment and carry a separate cost, typically £150 to £400
- iTero digital scan: the 3D digital scan used for treatment planning may be included in the consultation fee or charged separately
- Number of review appointments: practices that schedule frequent reviews add more clinical time and support, which is reflected in the overall fee
Is Invisalign available on the NHS?
Invisalign is not available through NHS dental treatment for adults. Adult orthodontics on the NHS is limited in availability and typically restricted to cases meeting specific clinical criteria through specialist orthodontic services, rather than routine cosmetic alignment. For patients seeking Invisalign in London, private treatment is the pathway. Fitzroy Dental Practice is a private clinic and does not provide NHS treatment.
Can Invisalign be used alongside composite bonding or with crowns?
Yes to both, with some important sequencing considerations. Invisalign can work around existing crowns and dental restorations, though attachments, small tooth-coloured buttons bonded to teeth that help the aligners grip, may not adhere as reliably to ceramic crowns as to natural enamel. Your dentist will plan around any existing restorations.
For patients wanting both Invisalign and composite bonding, the standard approach is to complete Invisalign first and then place bonding once the teeth are in their final position. Doing it in reverse means the bonding may need replacing or adjusting once the teeth move. An Invisalign and composite bonding package, treating both together in the correct sequence, is something many patients at Fitzroy discuss at their smile consultation.
How does Invisalign compare with other clear aligners in London?
Invisalign is the most clinically established clear aligner brand, with the largest body of long-term outcome data and the most extensive network of trained providers. Other aligner brands, including several UK-based alternatives, offer broadly similar mechanisms at varying price points.
The key differences between Invisalign and competitors are: the SmartTrack material used in Invisalign aligners, which is designed for consistent, controlled force; the ClinCheck 3D treatment planning software, which allows both dentist and patient to preview the planned result before starting; and the breadth of clinical support and training available to Invisalign-certified providers.
What should I look for in an Invisalign dentist in London?
Invisalign certifies providers at different tiers based on case volume, with Gold, Platinum, Diamond, and higher status awarded to practices treating larger numbers of patients per year. A higher provider tier indicates greater clinical experience with the system, which matters particularly for more complex cases. Ask your prospective dentist about their Invisalign provider status, the number of cases they complete annually, and whether orthodontic referral is available for cases beyond their scope.
At Fitzroy Dental Practice, our Invisalign-certified dentists carry out a thorough clinical assessment before recommending any treatment, including an honest discussion of whether Invisalign is the most appropriate option for your specific case or whether a different approach would serve you better.
How do I know if Invisalign is suitable for my teeth?
The clearest answer comes from a clinical examination and a digital scan. Invisalign suits a wide range of mild to moderate crowding, spacing, and bite issues. More complex cases, particularly those involving significant vertical movement, severe rotations, or skeletal discrepancies, may be better served by fixed braces or a combined approach. Your dentist will tell you honestly at consultation which category your case falls into, rather than fitting every patient into the same treatment regardless of suitability.
How long does Invisalign treatment take, and how often do I need appointments?
Treatment duration varies with case complexity. Invisalign i7 cases typically complete in two to three months. Lite cases usually take four to six months. Moderate and Comprehensive cases typically run from nine to eighteen months, with some complex cases extending beyond this. Each aligner tray is worn for one to two weeks before progressing to the next, and most patients wear aligners for twenty to twenty-two hours per day.
Review appointments with your dentist are typically scheduled every six to eight weeks. These allow the dentist to check that tooth movement is progressing as planned, fit new attachments if needed, and identify any early issues before they affect the final result.
What happens if I do not wear my Invisalign aligners enough?
Consistent wear time is the single most important factor in treatment success. Wearing aligners for significantly fewer hours than recommended each day slows tooth movement and can mean teeth do not reach the planned positions within the expected timeframe, requiring additional aligners. Patients who are honest with themselves about their ability to commit to twenty-plus hours of wear per day tend to achieve the best outcomes. If compliance is a concern, your dentist can discuss whether a different treatment approach might suit your lifestyle better.
What finance options are available for Invisalign in London?
At Fitzroy Dental Practice, we offer 0% interest-free finance over twelve months with no deposit required, making Invisalign treatment accessible without the full fee upfront. For more extensive cases, longer finance terms may also be available. Finance allows patients to access treatment with an experienced, well-equipped team rather than choosing a less suitable provider purely on the basis of upfront cost.
Is Invisalign worth the cost compared with fixed braces?
For patients who are suitable candidates, most find Invisalign worth the investment for several reasons: the aligners are virtually invisible during treatment, they are removable for eating and cleaning, and they cause less gum irritation than fixed brackets for most patients. The cost is typically comparable with or slightly higher than quality fixed brace treatment at a private practice. For mild to moderate cases where both options are clinically valid, the choice usually comes down to patient preference and lifestyle.

Common Questions Asked About Invisalign Cost
How much do 3 months of Invisalign cost?
Three months of Invisalign does not have a fixed price because treatment costs depend on the complexity of your case and the number of aligners required. At Fitzroy Dental Practice, clear aligner treatment starts from £2,500, with the final cost confirmed after assessment.
What is the 30-minute rule with Invisalign?
The 30-minute rule with Invisalign refers to limiting the time your aligners spend outside your mouth so you maintain the recommended daily wear. Invisalign generally requires around 20–22 hours of wear each day, with aligners removed for eating, drinking anything other than water and oral hygiene.
What is the lowest price for Invisalign in the UK?
The lowest Invisalign price varies between providers and depends on treatment complexity, so no single UK-wide price applies. Fitzroy Dental Practice lists clear aligner treatment from £2,500, with the final fee based on your personalised treatment plan.
Is 35 too old for Invisalign?
No, Invisalign is suitable for many adults, including people aged 35 and over. Your dentist assesses your teeth, gums, bite and orthodontic needs to determine whether clear aligners are appropriate for your treatment.
Why don't dentists recommend Invisalign?
Dentists recommend Invisalign when clear aligners provide suitable control for the required tooth movements. Some complex cases require alternative orthodontic treatment, so your dentist should assess your bite, tooth position and overall oral health before recommending Invisalign or another option.
Does Invisalign really take 2 years?
No, Invisalign does not always take two years. Invisalign reports an average treatment time of around 12–18 months, while mild cases can take as little as six months; treatment length depends on your individual orthodontic needs.
