Crowding — overlapping front teeth straightened
Invisalign · Cost Guide
In the UK, Invisalign typically costs £2,500–£5,500, depending on how much movement is needed. At Dr. Albert Gajdos in Windsor, it’s from £2,950 for a single arch, £3,500–£4,500 for both, and from £4,500 for complex cases — from around £150 a month with 0% finance.
The detail
Invisalign isn’t one flat fee — a handful of things move your quote up or down. Here’s what actually shapes the cost.
Straightening a single arch costs less than treating both. Most people who want an even smile treat both — and for most patients, dual-arch treatment is needed to get a good bite and proper function at the end.
Minor crowding or a relapse needs fewer aligners than a complex bite correction — the more movement, the higher the fee.
Extra “refinement” aligners to perfect the finish are planned into a good-quality case rather than charged as surprises.
Cosmetic-led treatment is planned for the best-looking result, and often paired with whitening and a little bonding to complete the smile.
Invisalign’s cost is really two things: the appliance and the treatments included with it (aligners, retainers, whitening, sculpting), and the dentist’s planning, oversight and care. At the cheapest end, some clinics leave out essentials like post-treatment retainers — which then arrive as unexpected add-on fees — or offer far less face-to-face planning and aftercare.
UK Invisalign prices generally run from £2,500 for short, simple cases to £5,500 for complex, comprehensive treatment, with most full cases landing around £3,500–£4,500. Our pricing sits within that range, planned and finished by a cosmetic dentist rather than delivered as a one-size-fits-all package.
No. Invisalign is private, cosmetic-led treatment. NHS orthodontics is reserved for under-18s with a genuine clinical need, and where it’s provided it’s normally fixed metal braces — not clear aligners. For adults, and for anyone wanting a discreet, cosmetic result, Invisalign is a private option.

Cost questions
Invisalign in the UK typically costs between £2,500 and £5,500, depending on how much movement is needed. Simple, short cases sit at the lower end; full treatment of both arches is usually £3,500–£4,500. At our Windsor practice, Invisalign is from £2,950 for a single arch, £3,500–£4,500 for both arches, and from £4,500 for complex cases.
Treating both arches — the most popular option — is £3,500–£4,500 with us, depending on the complexity of the case. Straightening just the upper or lower teeth (a single arch) starts from £2,950.
Yes. We offer 0% finance over 12–18 months, and many patients pay from around £150 per month. Longer plans are also available at a low fixed rate. Everything is subject to status, and your exact monthly figure is confirmed at your consultation.
No — Invisalign is a private, cosmetic-led treatment and isn’t offered on the NHS. NHS orthodontics is limited to under-18s with a clear clinical need, and where it is provided it’s usually traditional metal braces rather than clear aligners.
The aligners are only part of it. A cosmetic dentist plans the final tooth positions by eye for the best-looking smile — not just a “technically straight” result — and refines every stage by hand. That planning, and the finishing (often whitening and a little bonding) is what turns straightening into a smile you love.
Yes — with Dr. Albert at our Windsor clinic, three sets of Vivera retainers (worth £495) and bespoke home whitening (worth £349) are included as standard with every Invisalign plan, at no extra cost. Your personalised plan is confirmed at your consultation, so everything that’s included is agreed up front, with no surprises.
