Dental Treatment Plans and Written Estimates: What Your Dentist Must Give You in Writing (2026 UK Guide)

Last updated: August 2026. Sources: NHSBSA, NHS.uk, legislation.gov.uk, the General Dental Council, the Dental Complaints Service, NHS England, NHS Inform Scotland, the Welsh Government and nidirect. NHS dental charges for England are correct as of 1 April 2026, and all sources were verified on 5 August 2026.

TL;DR Your dentist must give you a written treatment plan before treatment starts. On the NHS in England that means an FP17DC for every Band 2 and Band 3 course, and for Band 1 courses containing private work. GDC rules require an updated plan in writing whenever the cost changes.

You are sitting in the chair and the dentist says you need a crown, maybe two, and mentions a number. You nod. Three appointments later the bill is bigger than the number you remember, and nobody can point to anything you were given at the start.

This is one of the most common and most avoidable disputes in UK dentistry, and the rules that prevent it are clear. Your dentist is not merely encouraged to write things down. Under General Dental Council standards they must give you a written treatment plan before treatment starts, and on the NHS in England a specific form is compulsory for most courses of treatment. This guide sets out exactly what you are entitled to receive, what it must contain, and what to do when the final bill does not match the estimate.

The short answer: what must be in writing before treatment starts

Two separate rulebooks apply, and both are on your side.

The first is professional regulation. Every dentist, hygienist and therapist on the UK register is bound by the GDC's Standards for the Dental Team, which applies to NHS and private treatment alike. Standard 2.3.6 is unambiguous [2]:

"You must give patients a written treatment plan, or plans, before their treatment starts and you should retain a copy in their notes. You should also ask patients to sign the treatment plan."

-- General Dental Council, Standards for the Dental Team, standard 2.3.6 [2]

The second is NHS charging law and the NHS contract. In England, a treatment plan form called the FP17DC must be issued for most NHS courses of treatment. It is not optional and it is not something you have to ask for.

Together these mean that for anything beyond a simple check-up, you should be leaving your first appointment holding a document that says what is being done and what it will cost.

NHS courses of treatment: when a written plan is compulsory

The NHS Business Services Authority, which administers NHS dental charging in England, sets out when the form is required [1]:

"An FP17DC or an FP17DC(w) must be issued to all patients for all Band 2 and Band 3 courses of treatment."

-- NHS Business Services Authority, guidance on FP17DC treatment plan forms [1]

A Band 1 course also requires one in two situations [1]:

• where it includes private treatment, such as a private hygienist appointment
• where the patient requests a treatment plan

Orthodontics has its own form. An FP17DCO or FP17DCO(w) must be completed for every course of orthodontic treatment [1].

So the practical rule for a patient in England is straightforward.

Those band figures rose on 1 April 2026 under the National Health Service (Primary Dental Services and Dental Charges) (Amendment) Regulations 2026, described in the instrument's own explanatory note as a routine inflation uplift [5]. Band 1 went from £27.40 to £27.90, Band 2 from £75.30 to £76.60, and Band 3 from £326.70 to £332.10 [5]. For the full breakdown of what sits in each band, see our complete guide to NHS dental charges.

One point that trips people up: you pay one band charge for a completed course of treatment, not one per appointment. NHS.uk puts it plainly, that if you need a mix of treatments from the same band you only pay the band charge once [4].

What your NHS treatment plan sets out

Practices do not all use the same piece of paper. Many generate the plan from their practice management software instead of using the printed NHS form, which is allowed, but only on conditions. NHSBSA states that a software-generated form "must be signed by the patient and include the same information as the treatment plan form" [1].

Whatever it looks like, an NHS treatment plan should tell you:

• Who is treating you, including the practice details and the performing dentist
• What is proposed under the NHS, itemised
• What, if anything, is proposed privately, itemised with a price against each line
• Which charge band applies to the NHS element
• The NHS charge payable and, separately, the private charge payable
• Where you sign to confirm you accept the treatment and the fees

The important structural feature is the split. NHS proposals and private proposals are recorded separately, with their own totals, so you can see at a glance which part of the work the NHS band charge covers and which part it does not.

Private treatment: what the GDC requires in writing

If you are paying privately there is no NHS form, and there is no NHS band charge to fall back on. The GDC does not set or cap private fees either, stating that "there are no set limits on what practices can charge for private dental treatment" [11]. The written plan is therefore doing more work in a private context, not less.

Standard 2.3.7 tells your dentist exactly what to include [2]:

"Whenever you provide a treatment plan you must include: the proposed treatment; a realistic indication of the cost; whether the treatment is being provided under the NHS (or equivalent health service) or privately."

-- General Dental Council, Standards for the Dental Team, standard 2.3.7 [2]

Note the phrase "a realistic indication of the cost". An estimate that is deliberately optimistic, or a range so wide it tells you nothing, does not meet that bar. If you are being quoted for implants, veneers or a full course of orthodontics, the plan is the document you will use to compare practices, so it needs real numbers. Our guides to private dentist prices across the UK and how NHS and private care compare on cost are useful benchmarks to hold a quote against.

Mixed NHS and private treatment: how it must be separated

Many courses of treatment are a blend. You might have an NHS filling and choose a private hygienist appointment in the same course, or accept an NHS extraction and pay privately for a replacement the NHS would not provide.

This is permitted, and NHSBSA is explicit about the paperwork [6]:

"The patient must be issued with a FP17DC form or equivalent documenting the NHS and private elements being provided under the planned Course of Treatment."

-- NHS Business Services Authority, guidance on mixing NHS and private dental treatment [6]

There is one carve-out worth knowing. Orthodontic provision must be entirely private or entirely NHS [6]. It cannot be split across the two within the same course.

The GDC standard reinforces the same principle from the professional side: where a plan is mixed, it "should clearly indicate which elements are being provided under which arrangement" [2].

If a practice tells you that some of the work is NHS and some is private but hands you a single undifferentiated total, that is the point to ask for the split in writing before you agree to anything.

When the bill is higher than the estimate

This is the situation the rules were written for, and the relevant standard is 2.3.8 [2]:

"You should keep the treatment plan and estimated costs under review during treatment. You must inform your patients immediately if the treatment plan changes and provide them with an updated version in writing."

-- General Dental Council, Standards for the Dental Team, standard 2.3.8 [2]

Read the two verbs. Informing you is a "must", and so is providing an updated version in writing. A change discovered mid-treatment is not, by itself, a problem. Teeth are unpredictable and a filling that turns out to need root canal work genuinely changes the plan. What the standard does not permit is you finding out at the reception desk when the card machine comes out.

On the NHS the practical consequence is that a new FP17DC should be issued with the amended plan. On private treatment, the updated written estimate is your evidence.

If you have been billed more than you were told, in writing, and no revised plan was ever given to you, you have a specific and well-founded complaint rather than a vague grievance. The escalation routes are set out below.

The price list your practice must display

Before you even reach a treatment plan, there is a baseline transparency requirement most patients have never heard of. GDC standard 2.4.1 requires a simple price list to be clearly displayed in the reception or waiting area, covering basic items including a consultation, a single-surface filling, an extraction, radiographs and hygienist treatment, with "from - to" ranges allowed for items that vary [2].

Standard 2.4.2 extends this to your practice literature and website: "You must give clear information on prices in your practice literature and on your websites - patients should not have to ask for this information" [2].

Standard 2.4.3 adds guarantees to the list. Practices should tell patients whether treatment is guaranteed, under what circumstances and for how long, and should make clear when it is not [2].

A practice that has none of this on display, on its website, or in its waiting room is not automatically doing anything wrong clinically. But it is a reasonable signal to weigh when you are choosing which practice to trust with a large course of work.

Two rules that can mean you owe nothing at all

Two protections sit inside English NHS charging law, and both are routinely confused with each other.

The 2-month rule. If you return within two months of completing an NHS course of treatment and need further treatment in the same or a lower charge band, there is no second charge. Regulation 6(4) of the National Health Service (Dental Charges) Regulations 2005 puts it this way [3]:

"Where a provider of relevant primary dental services has completed a course of treatment other than an urgent course of treatment but, within 2 months of that course of treatment being completed, the same provider determines that the patient requires further treatment which falls within the same or a lower charging band ... no charge may be made or recovered in respect of that further treatment."

-- National Health Service (Dental Charges) Regulations 2005, regulation 6(4) [3]

NHSBSA restates the same rule for patients in plainer language, framing it as returning to your dental practice within two calendar months of completing a course of treatment and needing further treatment from the same charge band or lower [16].

Two details matter. The regulation refers to the same provider, meaning the practice holding the NHS contract, and it applies to the same or a lower band. Going back for a Band 3 crown after a Band 2 course is an upward move, so it is chargeable.

The 12-month replacement guarantee. Separately, regulation 6(1) provides that where a restoration provided under a charged NHS course of treatment has to be repaired or replaced within 12 months to secure oral health, no charge may be made or recovered for that repair or replacement [3]. Exceptions apply, including where the restoration was recorded at the time as temporary, or where the damage results from trauma [3].

Neither protection applies to private treatment. If your course of treatment is private, your remedies come from consumer law and the practice's own guarantee terms, which is exactly why standard 2.4.3 requires those terms to be spelled out.

Signing the plan: what you are agreeing to

You will normally be asked to sign. GDC standard 2.3.6 says the dentist "should also ask patients to sign the treatment plan" [2], and NHSBSA requires a patient signature on any software-generated equivalent of the NHS form [1].

Signing records that the proposed treatment and the associated fees were explained to you and that you accept them. It does not lock you into treatment you later decline, and it does not waive the requirement in standard 2.3.8 for an updated written plan if things change [2].

Do not sign a plan with blank cost boxes, and do not sign one you have not read. If you want time, say so. A plan discussed today can be signed at the next appointment.

If you are claiming free NHS treatment

Where you are exempt from NHS charges, you make that declaration on the treatment plan or charge form, and the responsibility for its accuracy is yours, not the practice's.

In England you can get free NHS dental treatment if you are under 18, or under 19 and in full-time education, if you are pregnant or have had a baby in the previous 12 months, if you are being treated in an NHS hospital by a hospital dentist, or if you or your partner receive certain qualifying benefits [12]. Holding an HC2 certificate from the NHS Low Income Scheme also gives full help with costs, while an HC3 certificate gives partial help [12]. Our full eligibility guide walks through each category.

Getting the declaration wrong has a specific consequence. If NHSBSA cannot confirm a claimed exemption it writes to you, and if you do not respond within 28 days it issues a Penalty Charge Notice. You then owe the original charge plus a penalty [7]:

"The penalty charge is 5 times the original amount owed, up to a maximum of £100."

-- NHS Business Services Authority, Understanding penalty charges [7]

A further surcharge can be added if the penalty notice itself goes unpaid for 28 days [7]. So check the exemption box you are ticking, and if you are unsure whether your benefit qualifies, ask before you sign rather than after.

Treatment plans in Wales, Scotland and Northern Ireland

Charging models diverge sharply across the UK, and 2026 widened the gap.

Wales. From 1 April 2026 Wales replaced its three fixed bands with a care-package model. A course of treatment is built from individually priced standard packages, such as a recall examination at £25.00, urgent care at £37.50, denture care at £86.40 or crown, bridge, inlay, onlay and veneer care at £140.44, each charged separately but capped at a maximum total of £384 per course of treatment [13]. Free treatment applies to under-18s, 18-year-olds in full-time education, pregnant patients and those within 12 months of giving birth, and recipients of qualifying benefits, with free examinations for under-25s and over-60s [13]. The Welsh treatment plan form is the FP17DC(w) [1].

Scotland. Everyone in Scotland gets free NHS dental examinations. Treatment is free for everyone under 26, for anyone pregnant or who has given birth in the last 12 months, and for those with a certificated income-based exemption [14]. Adults who do pay contribute 80% of the treatment cost, capped at a maximum of £384 per course of treatment [14]. On the paperwork, NHS Inform is direct: "If you need treatment, your dentist will provide you with a treatment plan", describing it as a document that explains the treatment you need and gives an estimate of what it will cost, and adding that your dentist "must also provide an itemised account, if requested" [14].

Northern Ireland. Charges are not banded. They are published each year in the Statement of Dental Remuneration under the column "patient's charges" [15]. Free treatment applies to those under 18, aged 18 and in full-time education, pregnant or within 12 months of having had a child, hospital inpatients treated by a hospital dentist, recipients of Pension Credit Guarantee Credit or relevant Universal Credit, war pensioners treated for an accepted disability, and Hospital Dental Service outpatients or Community Dental Service patients [15]. If you are registered for Continuing Care, you can ask for a treatment plan, which nidirect confirms "is free and explains: what treatment your dentist recommends; the price for each part of the treatment; the likely total cost" [15].

The common thread is that in every UK nation you are entitled to see the cost of the work before it begins.

What a good treatment plan looks like, and the red flags

A plan you can act on has all of the following:

• Every proposed item listed separately, not bundled as "restorative work"
• A price against each private item, and the band and charge for the NHS element
• A clear NHS and private split where the course is mixed
• A total you can compare with another practice
• A date, the practice's details, and space for your signature
• Some indication of sequencing, so you know what happens at which appointment

The red flags are the mirror image:

• A verbal figure with nothing on paper
• A single total with no itemisation
• Blank cost boxes you are asked to sign around
• Reluctance to give you a copy to take away
• No displayed price list and no prices on the practice website, contrary to standards 2.4.1 and 2.4.2 [2]
• Pressure to start treatment the same day on a large, elective, high-cost plan

None of these is proof of anything improper on its own. All of them are reasonable grounds to slow down.

What to do if you were never given anything in writing

Start at the practice. Ask, in writing, for a copy of your treatment plan and an itemised account. Practices are required to operate a complaints procedure, and most disputes about an unexpected bill are resolved at this stage once the paperwork is produced.

If that does not resolve it, the route depends on how the treatment was funded.

NHS treatment in England. Complaints about primary care dentistry now go to your local Integrated Care Board, not to NHS England centrally. NHS England's own complaints page instructs patients to "Contact your local integrated care board (ICB) for complaints about primary care services (GPs, dentists, opticians or pharmacists)" [8]. If the ICB does not resolve it, the Parliamentary and Health Service Ombudsman is the final stage [9].

Private treatment. The Dental Complaints Service, funded by the GDC, helps resolve private dental complaints and can facilitate explanations and apologies, refunds for failed treatment, remedial treatment by agreement, and contributions toward remedial work capped at the original cost [10]. It cannot help with complaints raised more than 12 months after the issue, with NHS treatment, with obtaining records, or with compensation for losses as distinct from a refund [10].

A word on the GDC itself. The GDC does not arbitrate billing disputes. Its own guidance states plainly that "We cannot resolve complaints or help with refunds" [9]. It investigates serious fitness to practise concerns, which is a different and much higher threshold.

Getting a second opinion before you accept a large quote

A written plan is portable. That is arguably its most useful property, and the one least often used.

If you have been quoted four figures for implants, a full-arch restoration or a long orthodontic course, you are entitled to take that plan to another practice and ask what they would propose and charge. You are not obliged to tell the first practice you are doing it, and a second opinion is not a complaint. Our guides to what implants typically cost in the UK and crown prices on the NHS and privately give you a sense of whether a quote sits inside the normal range.

If the two plans differ substantially, that difference is information. Sometimes it reflects a genuinely different clinical approach, sometimes a different material, and sometimes simply a different pricing structure. The plan is what lets you tell which.

Frequently asked questions

Does a dentist have to give you a written treatment plan in the UK?

Yes. GDC standard 2.3.6 requires a written treatment plan before treatment starts, for NHS and private care alike. On the NHS in England an FP17DC form is compulsory for all Band 2 and Band 3 courses, and for Band 1 courses that include any private treatment or where you request one.

Is a dental treatment plan legally binding?

A treatment plan is not a fixed-price contract. It is a record of what was proposed and what it was expected to cost. If the plan changes, GDC standard 2.3.8 requires your dentist to tell you immediately and give you an updated version in writing, which is what makes an unexplained increase challengeable.

Can a dentist charge more than the estimate they gave me?

Costs can change if the clinical picture changes, but you must be told immediately and given a revised written plan before the extra work goes ahead. A bill that exceeds your written estimate with no updated plan is a legitimate complaint. Raise it with the practice first, then your ICB or the Dental Complaints Service.

Do I get a treatment plan for a routine check-up?

Not automatically. A Band 1 course in England only requires an FP17DC if it includes private treatment, such as a private hygienist appointment, or if you ask for one. You are always entitled to ask, and it is worth doing if any part of the appointment is being charged privately.

What is an FP17DC form?

The FP17DC is the NHS personal dental treatment plan used in England, with FP17DC(w) in Wales and FP17DCO for orthodontics. It records the proposed NHS and private treatment separately, the charge band, the amounts payable, and your signature. Practices may use a software-generated equivalent containing the same information.

Do I have to sign a dental treatment plan before treatment starts?

You will normally be asked to. Signing records that the treatment and fees were explained and accepted. It does not commit you to treatment you later decline, and it does not remove your dentist's obligation to issue an updated written plan if the treatment or the cost changes partway through.

Can I take my treatment plan to another dentist for a second opinion?

Yes. The plan is yours, and a second opinion is a normal part of deciding on expensive elective work such as implants, veneers or orthodontics. Another practice can quote against the same proposal, and any difference between the two plans tells you something useful about approach or pricing.

What if I was never given a plan and the bill was more than I expected?

Ask the practice in writing for your treatment plan and an itemised account, and use its complaints procedure. If it is unresolved, NHS complaints in England go to your local Integrated Care Board, then the Ombudsman. Private complaints go to the Dental Complaints Service, which has a 12-month time limit.

Before you accept a quote, see what else is available

A written treatment plan does its best work when you have something to compare it with. If a quote does not sit right, or you simply want a second view before committing to a large course of treatment, it is worth seeing which practices near you are taking patients and what they offer.

Search for a dentist near you on Dentists Closeby to compare GDC-registered practices in your area, then take your written plan along and ask what they would propose. You can also read our guide to registering with a dental practice and our overview of ways to spread the cost of dental treatment.
