How much does Invisalign® cost in the uk? A realistic breakdown

“how much does Invisalign® cost?” is one of the most common questions we are asked. The honest answer is that it depends on what your teeth need. But that does not mean you should be left guessing. Here is a clear, realistic breakdown of Invisalign® costs in the uk, and what you can expect to pay at castle street.

Why Invisalign® prices vary

The cost of Invisalign® depends mainly on how much movement your teeth need and how long treatment takes. A small amount of crowding at the front might be corrected in a few months, while more complex bite problems need a longer course with more aligners.
Prices also vary between practices depending on the experience of the provider, what is included, and the aftercare offered.

Typical uk prices

Across the uk, Invisalign® treatment typically ranges from around £2,000 to £5,500, depending on the complexity of the case and where you have treatment.

Invisalign® prices at castle street

  • Full orthodontic assessment: £25 (refundable against treatment if you go ahead)
  • Invisalign® lite: from £2,900, for mild crowding or spacing
  • Invisalign® moderate: from £3,400, for moderate cases
  • Invisalign® full: from £3,900, for more complex cases
  • Retainers: from £250, or vivera retainers from £500

You can see our full price list on our fees page.

What should be included?

When comparing prices, it is worth checking exactly what is included. A good Invisalign® package should cover:

  • A full assessment and digital scan
  • A treatment simulation so you can see your expected result
  • All your aligners
  • Regular review appointments throughout treatment
  • Any refinement aligners needed to fine-tune your result

Remember to factor in retainers. Keeping your teeth straight after treatment is just as important as moving them.

Is Invisalign® worth it?

Straighter teeth are not only about looks. They are often easier to clean, which can reduce the risk of decay and gum disease, and a well-aligned bite can put less strain on your teeth and jaw. Many of our patients tell us that the boost in confidence is worth every penny.
