Orthodontic Deposits and Refunds UK — Know Your Rights Before You Pay

How much deposit do orthodontic practices typically require?

The deposit required to secure orthodontic treatment in the UK varies by practice and treatment type but typically falls between £200 and £1,000. For clear aligner treatment — particularly with systems such as Invisalign, where the laboratory fee is paid upfront by the practice — deposits at the higher end of this range are common. For fixed brace treatment, deposits of £200 to £500 are more typical. The deposit is usually taken at or shortly after the consultation, once a treatment plan has been agreed and the patient contract has been signed. Some practices take a smaller initial payment to cover records (photographs, radiographs, and study models or scans) at the consultation stage, then request the main deposit when treatment is confirmed. It is worth clarifying which of these applies and what each payment covers.

What the deposit should legitimately cover

A reasonable orthodontic deposit should cover the costs the practice has genuinely incurred in preparing your case. This includes the cost of clinical records — digital scans, photographs, and radiographs — the consultation time, and any laboratory fees already paid, such as the cost of manufacturing your first set of aligners if treatment has been ordered. Deposits that are large in proportion to the work done at that stage — for example, a £1,000 non-refundable deposit taken before any records are made — are harder to justify. A clear itemised breakdown of what the deposit covers should be provided in writing before you pay. If a practice cannot explain what the deposit represents, that is a red flag.

Cooling-off rights under the Consumer Contracts Regulations 2013

The Consumer Contracts Regulations 2013 provide a 14-day cooling-off right for distance and off-premises contracts — for example, where a contract is signed online or at your home rather than at the trader's premises. However, the majority of orthodontic treatment contracts are signed at the dental practice, which is the trader's permanent place of business. In-premises contracts of this kind do not benefit from the statutory 14-day cooling-off right. This means that once you have signed an orthodontic treatment contract at a dental practice and paid a deposit, there is no automatic legal right to cancel and receive a full refund within 14 days. Some practices voluntarily offer a cooling-off period as a matter of good practice — it is worth asking before signing whether this is available. The absence of a statutory right does not mean refunds are impossible; it means the practice's own contract terms govern what happens if you cancel.

What should be in the written contract before you pay

Before paying any deposit, you should have a signed written contract that clearly states the total treatment fee, the payment schedule, what is included and excluded from the quoted fee, the cancellation and refund policy, what happens if treatment takes longer than planned, the policy on missed appointments and any associated charges, and the practice's obligations to you if they close or are unable to complete treatment. Contracts that are vague on any of these points — particularly the cancellation and refund provisions — expose you to significant financial risk. Do not sign a contract you have not read in full, and do not pay a deposit before the contract is in place. Verbal assurances about refund policies are not enforceable.

What happens if you cancel after treatment has started

If you cancel after active treatment has begun, the situation is more complex. The practice has incurred real costs — laboratory fees, clinical time, materials, and ongoing case management — and is entitled to be compensated for work genuinely carried out. A fair cancellation policy deducts the actual costs incurred from the total fee and refunds the balance. An unfair policy deducts a disproportionate amount that significantly exceeds the work done, effectively penalising the patient for leaving. The Competition and Markets Authority (CMA) has guidance on unfair contract terms in consumer contracts — clauses that allow a business to retain a disproportionate amount on cancellation may be unenforceable under the Consumer Rights Act 2015. If you are considering cancelling mid-treatment, ask for an itemised account of costs incurred to date before agreeing to any deduction.

Mid-treatment abandonment and cost recovery

Where a patient stops attending without formally cancelling — for example, by simply not returning after a number of appointments — the practice may treat this as abandonment and retain the deposit plus any additional fees due under the contract. This situation creates the worst outcome for both parties: the patient loses money and ends up with incomplete treatment, and the practice has provided partial treatment with no clear resolution. If you are considering leaving a practice mid-treatment for any reason — dissatisfaction with results, financial difficulties, relocation, or concerns about clinical standards — the correct approach is to formally communicate this in writing and request an itemised account of costs to date. Stopping attendance without notice does not extinguish your financial obligations under the contract.

What to do if a practice refuses to refund you

If you believe you are entitled to a refund and the practice is refusing unreasonably, there are several avenues available. First, send a formal written complaint to the practice, citing the specific contract terms and any relevant consumer law provisions. Most disputes resolve at this stage. If the practice does not respond or refuses to engage, you can escalate to their Alternative Dispute Resolution (ADR) provider. Under the Alternative Dispute Resolution for Consumer Disputes Regulations 2015, dental practices in England and Wales are required to signpost patients to an approved ADR scheme if a complaint cannot be resolved internally. The Dental Complaints Service (operated by the GDC) handles complaints about private dental treatment and can help mediate disputes, including those involving financial matters. Trading Standards can investigate businesses that appear to be using unfair contract terms. For amounts under £10,000, the small claims court (Money Claims Online) is an accessible last resort.

NHS orthodontic treatment — no deposit required

NHS orthodontic treatment for eligible patients — primarily children and young people under 18 who meet the IOTN (Index of Orthodontic Treatment Need) criteria — is provided free of charge. There is no deposit requirement and no payment at any stage for treatment provided under the NHS pathway. Adults are very rarely eligible for NHS orthodontic treatment; where they are, the same no-deposit, no-charge rules apply. If you are approached by any provider — NHS or private — asking for a deposit for treatment that is supposed to be free under the NHS, this should be queried immediately and reported to NHS England if appropriate.
