How to Switch Dentists in the UK 2026: NHS Records, Costs and What to Tell Your New Practice

Last updated: May 2026. Reviewed by the Dentists Closeby editorial team. Sourced from NHS.uk, NHS England, NHSBSA, the Information Commissioner's Office (ICO), the General Dental Council (GDC), the Care Quality Commission (CQC), Healthwatch England, NHS Inform Scotland, the Welsh Government, the Dental Complaints Service and the published terms of Denplan and Bupa Dental Care.

TL;DR: You do not need to deregister to switch NHS dentists in England, because no formal lifetime registration has existed since 2006. Request your records under UK GDPR (one calendar month, usually no fee), finish any open course of treatment to keep your 12-month repair guarantee, then book in at a new practice. Scotland and private plans differ.

A 2024 Healthwatch England poll found that 68% of UK adults believe they have a permanent right to sign up with an NHS dentist the way they do with a GP [1]. That belief is wrong, and untangling it is the single most useful thing you can do before moving practices. Once you understand how the modern NHS dental contract actually works, switching becomes an administrative job of three or four phone calls, not a months-long ordeal.

This guide explains how to switch dentists in the UK in 2026, covering NHS rules in England, the materially different position in Scotland and Wales, your records access rights under UK GDPR, what happens to a mid-band course of treatment, the 12-month NHS repair guarantee, private plan exits with Denplan and Bupa, and the practical steps to find a new dentist when nearly half of practices show no NHS capacity for adults [2].

The Myth of NHS Dental Registration

You do not need to deregister from your current NHS dentist before joining a new one in England. The 2006 NHS dental contract reforms abolished formal lifetime registration. Since then, the relationship between you and your dentist lasts only as long as an active course of treatment.

NHS.uk states the position directly:

"At your first visit, you may be asked to fill out a form to register with the dental practice, but this does not mean you'll always be able to get NHS dental care at the same dental practice in the future." [3]

Healthwatch England's 2025 guidance puts it even more plainly: "the arrangement between a dentist and patient only lasts as long as your course of treatment. It doesn't give you the right to stay permanently registered." [4]

In practice this means three things. First, you do not need to ask permission or fill out a "deregistration" form. Second, your old practice has no contractual obligation to keep seeing you on the NHS once your last course of treatment is closed. Third, the 24-month "we will remove you from our list" letter that some practices send is a practice-level administrative policy, not an NHS-mandated rule [5]. You are not being expelled from the NHS, only from one practice's internal patient list.

Scotland Is Different

If you live in Scotland the rules are materially different. NHS Inform Scotland confirms that "when you register with a dentist you'll be registered for life, unless you or your dentist requests that your registration is withdrawn" [6]. Registration transfers automatically if you attend a different NHS dentist for treatment, and a Scottish dentist must give at least three months' notice before withdrawing you from their list (with limited exceptions for violence or serious misconduct).

Wales: A New Contract from April 2026

Wales replaced the NHS dental Units of Dental Activity model in April 2026 and now operates a Dental Access Portal for patients without an NHS dentist [7]. If you already have a Welsh NHS practice, the Welsh Government's guidance is to call them directly for routine and emergency appointments. If you want to change practice, the Dental Access Portal is currently the route to express interest in alternative provision when capacity becomes available.

Northern Ireland operates a devolved system that is not covered in detail in this guide. If you live in Northern Ireland, check with your Health and Social Care Trust before relying on the England-specific rules below.

Before You Switch: Five Questions to Answer First

Switching is rarely urgent, and a few minutes of preparation prevents almost all of the avoidable problems. Before you contact a new practice, work through these five questions about your current arrangement.

1. Is there an open course of treatment? If your dentist has started a Band 2 (filling, root canal, extraction) or Band 3 (crown, bridge, denture) course, finishing it at the original practice is almost always cheaper than restarting elsewhere.
2. Is anything still under the 12-month NHS repair guarantee? Crowns, fillings, root fillings, inlays and onlays placed under the NHS are guaranteed for 12 months at the original practice [8]. Switching forfeits practical access to that remedy.
3. Are you mid-pathway on an NHS referral? A referral to oral surgery or hospital orthodontics is held by the secondary care provider, not your primary dentist, so it generally survives a switch. Phone the secondary care team to confirm before you move.
4. Are you on a private plan? Denplan, Bupa and similar capitation plans have notice periods (commonly 14 to 21 days), and the plan ends on the final day of the cancellation month [9]. Trigger the cancellation before you book in elsewhere.
5. Do you have an open complaint? A complaint can continue once you switch, but practical remedies such as free remedial treatment become much harder to collect once the relationship has ended.

If the answer to any of the first three is "yes", staying at your current practice for one more visit is usually the right call. The administrative job of switching can wait a fortnight.

How to Get Your Dental Records: UK GDPR in Plain English

Your records belong to you in the data-protection sense. Under the UK General Data Protection Regulation (UK GDPR) and the Data Protection Act 2018, every UK dental practice must give you a copy of the personal information they hold about you when you ask. The mechanism is called a Subject Access Request, often shortened to SAR.

What you can ask for

Clinical notes, X-rays, treatment plans, consent forms, photographs, dental impressions or scans, referral letters and internal communications that identify you (a receptionist's email about a missed appointment, for example) are all covered. NHS England's published guidance confirms that UK GDPR grants individuals "the right of access to their personal data from any person or organisation that holds information about them" [10]. The General Dental Council's Standards for the Dental Team, Principle 4, states that "patients have the right to access them under Data Protection legislation" and that practitioners "must arrange for this promptly, in accordance with the law" [11].

The three rules that matter

1. Time limit: the practice must respond within one calendar month of receiving your request. The clock can be extended by up to two further months if your request is genuinely complex, but the practice has to tell you (and explain why) within the first month [12].
2. Fees: in the vast majority of cases the records are free. The ICO is explicit that an organisation "can charge a reasonable fee to cover their administrative costs if they think your request is 'manifestly unfounded or excessive'" or if you are asking for further copies of information you already have [13]. Standard SAR for a single patient's records does not meet that bar.
3. Format: the GDC requires records to be "clear, legible, accurate, and can be readily understood by others" [11]. In practice you may receive paper printouts, PDFs, or digital X-rays on a CD or via secure portal. Practices are not legally required to convert formats they do not already use.

How to make the request

Email or write to the practice. State that you are making a Subject Access Request under UK GDPR and the Data Protection Act 2018, give your full name, date of birth, NHS number if you have it, and any patient reference. Specify that you want all clinical records, X-rays and correspondence. The practice may ask for ID. Keep a copy of your request and the date you sent it.

Records must be retained by NHS dental practices for at least 11 years for clinical care records, so even if you switched several years ago you can still ask for them [14]. NHS England's Records Management Code of Practice recommends 25 years of age (or 26 if treatment concluded at 17) for children's records.

What Happens to Your Mid-Treatment NHS Charge

Switching mid-band almost always means paying twice. There is no NHS mechanism for transferring an unfinished course of treatment between practices, and no refund for choosing to leave with work outstanding.

Here is how it works. NHS dental treatment is paid for by course, not by appointment. As of April 2026 the three NHS bands in England are:

If you have paid £76.60 for a Band 2 course, had two of three planned fillings, and then switch, your old practice records the course as incomplete on the FP17 form. You do not get a refund. Your new practice opens a fresh course of treatment, and you pay again from the appropriate band [15].

NHS.uk does offer a "two-month rule" that lets a course continue with no further charge if you need additional treatment of the same band or lower within two months [16]. This rule is per-practice. It does not transfer when you switch.

The cleanest financial path is therefore to ask your current dentist when the open course of treatment ends, attend that final appointment, and switch the week after.

The 12-Month NHS Repair Guarantee: Why Timing Matters

If your NHS dentist has fitted a filling, root filling, inlay, onlay, porcelain veneer or crown in the last 12 months, that work is guaranteed by the NHS. The NHSBSA confirms:

"Some NHS dental treatments are guaranteed for 12 months. You'll not be charged if any of these need to be repaired or replaced within 12 months of the original being fitted." [8]

The guarantee is held by the practice that did the original work, not by the NHS as a whole. If a filling fails six months after you switched dentists, the practice that placed it must repair or replace it free of charge, but only if you go back to them. Your new dentist can refuse to honour another practice's guarantee, and almost always will, because the new practice is not party to the original NHS claim.

Some exclusions apply. The guarantee does not cover trauma damage, work that was always intended to be temporary, or restorations where a private treatment has since been provided on the same tooth.

The practical takeaway: if recent NHS work feels even slightly unstable, get it checked at the original practice before you switch. Once you have moved, returning to the old practice for a free repair is socially awkward and logistically harder, even though the right itself remains.

Switching a Private Plan: Denplan and Bupa Dental Care

Private capitation plans add a contract layer on top of the patient-dentist relationship. Cancelling the plan is a separate step from changing dentist, and the two have to be coordinated.

Denplan

Denplan, owned by Simplyhealth, requires 21 days' notice to cancel a plan, and "your Denplan agreement ends on the final day of the month in which you submit your cancellation request" [17]. The process has three steps.

1. Tell your current dentist that you are leaving. They complete a Patient Leaving Form on your behalf.
2. Phone Denplan on 0800 401 402 to confirm the cancellation and the final billing date.
3. Register with a new Denplan provider (or, if you are leaving Denplan entirely, with a new dentist of any kind).

Denplan recommends "scheduling a final appointment before departing, as you'll establish a fresh contract with the new dentist, and any untreated dental issues discovered then will be charged privately." [17] Monthly premiums at the new practice can be different from your previous payment, because each Denplan dentist sets their own fees. Rejoining Denplan within six months of leaving avoids a fresh registration fee.

Denplan's published patient pages do not specify whether unused prepaid months are refunded on cancellation. If you have paid an annual lump sum and are switching part-way through the year, ask Denplan directly. The Consumer Rights Act 2015 entitles you to a refund "without undue delay, and in any event within 14 days" if a service has not been delivered as contracted [18], which gives you a fallback if a plan provider refuses pro-rata repayment.

Bupa Dental Care

Bupa's Smile Plan Agreement gives a 14-day cooling-off period during which you can cancel for any reason [19]. The notice period after that 14 days is not specified clearly in Bupa's published patient documents. If you are on a Bupa plan, ring them on 0800 237 777 with your plan number to hand, and ask for the cancellation notice period in writing.

Bupa also notes that the dentists on its lists "will change from time to time", so it is worth confirming whether your preferred new dentist is on the Bupa network before you cancel.

Plans more generally

For any UK private dental plan, the same approach applies: read the contract, give notice in writing, expect a one to three month wind-down, and only switch dentist once the plan cancellation date is confirmed. If a plan provider refuses a refund you believe you are entitled to under the Consumer Rights Act 2015, escalate to Citizens Advice or the Financial Ombudsman Service.

Free NHS Treatment Eligibility: HC2, Pregnancy and Benefits

Free NHS dental treatment is attached to you, not to your practice, so it transfers automatically when you switch. NHS.uk lists the categories of patient who qualify [20]:

• Under 18 (or under 19 in full-time education)
• Pregnant or having given birth in the last 12 months (or had a stillbirth in the last 12 months)
• Receiving income-related Employment and Support Allowance
• Receiving Pension Credit Guarantee Credit
• Receiving Universal Credit with income below the specified threshold
• Holding an HC2 certificate from the NHS Low Income Scheme
• Being a dependent under 20 of a qualifying benefit recipient

You simply present your HC2, maternity exemption certificate, or evidence of qualifying benefit at the new practice. There is no need to inform your old practice or formally transfer anything. Maternity Action confirms that the Maternity Exemption Certificate is portable across any NHS dental practice in England during pregnancy and for 12 months after the birth [21].

Two practical notes. First, certificates expire, so check yours is in date before your first new appointment. Second, you must show the certificate at each course of treatment to qualify for that course's free status, just as you would have at your previous practice.

Special Cases: Children's Orthodontics, Referrals and Open Complaints

Children mid-NHS orthodontics

NHS orthodontic treatment for under-18s is funded based on the Index of Orthodontic Treatment Need (IOTN) score recorded at the start of the original course. If your child is mid-treatment and you need to switch (often because you are moving area), the receiving practice has to "open a new course of treatment" and "must contact your Commissioner for confirmation they would allow this" [22]. The original IOTN score and the child's age at the start of treatment carry over, so eligibility is preserved, but the new practice will need a transfer letter from the previous orthodontist describing what has been fitted and what remains. Phone the original practice and ask them to email this directly to the new orthodontist.

Open referrals to oral surgery or hospital dentistry

A referral to secondary NHS care is held by the receiving hospital, not your primary dentist. In most cases your place on the waiting list is unaffected by switching practice. Phone the secondary care team that received the referral to confirm your details remain on file. If your clinical situation has changed since the referral was made, the new dentist may need to issue an updated referral, which can mean a fresh Band 1 charge and a short delay.

Open complaints

You do not have to remain a patient of a practice while a complaint is being investigated. The Dental Complaints Service, which handles private dental complaints, accepts cases for up to 12 months after the treatment or 12 months after you became aware of the issue [23]. NHS complaints go through the practice's internal procedure first, then the NHS England Customer Contact Centre on 0300 311 2233, and finally the Parliamentary and Health Service Ombudsman. None of these routes requires you to remain a registered patient.

The practical wrinkle is the remedy. If the outcome you are seeking is free remedial treatment from the original practice, that becomes much harder to deliver once the relationship has ended. If you are seeking a refund or a finding from the GDC, switching has no effect on the process.

How to Find a New NHS or Private Dentist

The NHS dental access situation in England remains constrained in 2026. NHS England's most recent GP Patient Survey shows that 78% of those who tried to get an NHS dental appointment in early 2025 were successful, a two percentage point improvement on 2024 but still 22% who could not [24]. Healthwatch England's 2025 analysis found that 48% of practices with published availability data show no capacity for new adult NHS patients, and that 32% of people in England now use private dentistry, up from 22% in 2023 [2]. Adult NHS access remains 16.4% below the April 2019 pre-pandemic baseline [25].

Against that backdrop, finding a new dentist takes a bit of patience and a methodical approach.

Step one: search by postcode

The official NHS finder is at nhs.uk/service-search/find-a-dentist. Enter your postcode and the tool returns nearby practices with opening times, services and any published indication of NHS capacity. Phone before you book to confirm the listing is current, because availability changes faster than the directory updates.

If no NHS practice with capacity is listed near you, NHS.uk advises contacting your local Integrated Care Board (ICB), or phoning the NHS England Customer Contact Centre on 0300 311 2233 [3].

You can also search Dentists Closeby for both NHS and private practices in your area, which combines the official NHS data with private listings, ratings and direct booking where available.

Step two: check CQC inspection reports

The Care Quality Commission inspects every dental practice in England. Unlike GP surgeries and hospitals, primary dental providers are not given star ratings, but inspection reports show which regulations were met or breached against five questions: Is it safe? Is it effective? Is it caring? Is it responsive? Is it well-led? [26]. Search for the practice name at cqc.org.uk and read the most recent report. A practice with multiple regulatory breaches in recent inspections is a meaningful warning signal.

Step three: the phone-call checklist

When you call a candidate practice, ask:

1. Are you currently accepting new NHS adult patients? Confirm explicitly, because finder-tool data lags.
2. What is the typical wait for a new patient examination?
3. Do you offer NHS, private, or both? If both, what are the trigger points for being moved to private?
4. What are your urgent and out-of-hours arrangements?
5. Is the practice accessible? Is sedation available if I need it?
6. Who would my named dentist be, and what continuity of care can I expect?
7. What is your complaints procedure? Every NHS practice is legally required to have one.

These questions are not from a single official checklist. They distil what the CQC inspection regime asks of practices and what NHS.uk and BDA patient guidance recommend that patients understand before booking.

Step four: book the first appointment

Once you have chosen a practice, book your first examination. You will fill in a registration form (which, despite the wording, is a practice-level administrative form, not the abolished NHS lifetime registration). Bring your HC2 or exemption certificate if you have one. If you have already requested your records from the old practice, ask them to forward to the new practice in advance, or take the printouts with you.

Frequently Asked Questions

Do I need to deregister from my current NHS dentist before switching?

No. Formal NHS dental registration in England was abolished by the 2006 contract reforms. Your relationship with a practice lasts only for the duration of an active course of treatment, so once that course is closed there is nothing administrative to cancel. Simply contact a new NHS practice and ask to register with them.

Can my old dentist refuse to give me my records?

No. UK GDPR and the Data Protection Act 2018 give you a right of access to all personal information a practice holds about you, including X-rays, photographs and clinical notes. The practice must respond within one calendar month, usually free of charge. The General Dental Council's Standard 4 confirms this is a professional obligation, not a courtesy.

Will I lose my 12-month NHS repair guarantee if I switch?

You keep the right, but lose practical access. The 12-month NHS guarantee on fillings, crowns, root fillings, inlays, onlays and porcelain veneers is held by the original practice. You can return there for a free repair, but your new practice is unlikely to honour another practice's guarantee, so most patients pay again rather than travel back.

What happens if I switch mid-band-2 course of treatment?

You will pay twice. Your old practice will record an incomplete course on the FP17 form and your £76.60 Band 2 charge is not refunded. Your new practice opens a fresh course of treatment and you pay the appropriate band again. The cleanest approach is to finish open courses at your current practice before changing.

Is dental treatment in Scotland different from England?

Yes, materially. NHS Inform Scotland confirms that you register for life with a Scottish dentist, that registration transfers automatically if you attend a different practice for treatment, and that your dentist must give at least three months' notice before withdrawing you from their list. Scotland is the only UK nation where the lifetime registration model survives.

How long does it take to cancel a Denplan or Bupa private plan?

Denplan requires 21 days' notice and the agreement ends on the final day of the cancellation month. Bupa's Smile Plan Agreement gives a 14-day cooling-off period; the ongoing notice period is set in your individual plan, so phone Bupa on 0800 237 777 to confirm. Coordinate the cancellation date with the start of your new arrangement.

Can I switch dentist if I have an open complaint?

Yes, but think about the remedy first. NHS complaints, GDC fitness-to-practise referrals and Dental Complaints Service cases all proceed independently of whether you remain a patient. However, if the outcome you want is free remedial work from the original practice, that becomes much harder to collect once you have switched. Wait if remedy delivery matters to you.

Will my free NHS dental treatment status carry across to a new practice?

Yes. Free NHS treatment eligibility is attached to your personal circumstances, such as pregnancy, qualifying benefits, or an HC2 certificate from the NHS Low Income Scheme. It is not tied to any specific practice. Show your certificate or evidence of benefit at your first new appointment and the entitlement applies as it did before.

A Final Word on Timing

The single biggest mistake people make is switching while a course of treatment is open. The NHS rules are designed around courses, not registrations, and almost every problem in this guide (paying twice, losing the 12-month guarantee, breaking continuity of orthodontic care) traces back to switching mid-course. If your last filling, crown or check-up was more than a few weeks ago and the practice has formally closed your course, you can switch the same day. If treatment is open, give it a fortnight, finish the work, and move with a clean ledger.

For most adults in England, the modern NHS dental contract is more flexible than people assume. There is no permanent registration to break, no fee to leave, and no limit on how many times you can change dentist over a lifetime. The constraint is capacity, not bureaucracy.

Search Dentists Closeby for an NHS or private dentist near you, check the CQC inspection report for any practice you are considering, and time your move around the end of an active course of treatment.
