A bright, confident smile never goes out of style. Teeth whitening is one of the most requested dental treatments in the UK. It helps to remove stains and restore natural brilliance. But how much does professional whitening actually cost, and what affects the price?
Most professional treatments range from £200 to £1,000. Dentist-supervised home kits cost less and whiten teeth slowly over time. In-clinic treatments, especially premium systems, cost more but make teeth visibly whiter in one visit.
In this guide, we’ll explain the different types of teeth whitening, the average costs across the UK, and what’s included in each treatment. You’ll also see Zental’s own transparent pricing so you can make an informed decision about your smile.
Before we dive in, here are the important facts you need to know:
Now let’s explore each option in detail so you can understand what affects the cost of teeth whitening in the UK.

Several factors influence how much you’ll pay for professional teeth whitening in the UK. Understanding them helps you compare clinics more confidently and know exactly what you’re paying for:
Teeth whitening prices in the UK vary depending on where you go, the treatment system that is used, and whether you choose an at-home or in-clinic option.
Other influences include location and the dentist’s experience. Existing dental work, such as crowns or veneers, may require additional adjustments to achieve an even result. Some clinics include follow-up care and whitening gels, while others charge separately.
Knowing what affects the cost helps you make an informed decision and choose the treatment that suits your needs and lifestyle.
| Treatment Type | Typical Cost Range | Treatment Setting |
|---|---|---|
| Over-the-counter kits | £6 – £120 | Retail (no dentist supervision) |
| Dentist-supervised home whitening | £200 – £450 | At home |
| In-clinic laser or LED whitening | £300 – £900 | Dental practice |
| Premium branded systems (Enlighten, Zoom) | £595 – £695 | Dental practice |
| Zental professional whitening | from £175 | Dental practice |
This option is one of the most popular in the UK. Your dentist provides custom-made trays and professional-strength whitening gel, which you use at home over one to two weeks. This option typically costs from £175 to £475 in the UK. Results appear gradually, giving you control over the final shade.
| Treatment Type | Cost Range | Best For |
|---|---|---|
| Home kit (single arch) | ~£175 | Mild staining, small areas |
| Home kit (both arches) | ~£350 | Full smile enhancement |
| Premium home kit (advanced system) | ~£475 | Stronger results and longer-lasting shade |
Tips and insights:
In-clinic whitening provides instant results. A stronger gel is applied to your teeth, often activated with an LED or laser light. The entire process takes about one hour and gives results several shades lighter in a single visit.
| Treatment Type | Cost Range | Treatment Time | Best For |
|---|---|---|---|
| Single-session in-clinic whitening | £300 – £600 | Around 1 hour | Quick results before a special event |
| Premium branded in-clinic whitening | £700 – £900 | 1–2 hours, includes desensitizing care | Deep stains and long-lasting brightness |
Tips and insights:
Some clinics offer branded systems like Enlighten EVO or Zoom Whitening, which combine home and in-clinic treatment for maximum results and minimal sensitivity.
| System | Cost | What’s Included | Best For |
|---|---|---|---|
| Enlighten EVO | £595 | Home + in-surgery whitening, guaranteed B1 shade result | Patients wanting guaranteed, natural white results |
| Zoom Whitening | £695 | In-clinic LED whitening plus take-home maintenance kit | Fast results and professional brightness boost |
Tips and insights:
You can also find whitening strips, LED kits, and gels in shops or online. They’re legal as long as the hydrogen peroxide concentration is low enough.
| Product Type | Price Range | Comments |
|---|---|---|
| Whitening strips | £6 – £25 | Mild whitening, minimal change |
| Mid-range home kits | £30 – £80 | Modest results with repeated use |
| Premium retail kits | £90 – £120 | Stronger gels, close to professional quality |
Tips and insights:
DIY kits are appealing because they’re easy to buy and often cost far less than professional whitening. They can help with light surface stains, but they don’t offer the same strength, consistency, or longevity as dentist-supervised treatments.
Professional whitening uses regulated gels, custom-made trays, and clinical guidance to deliver brighter, longer-lasting results. It also keeps your teeth and gums safe throughout the process.
| Feature | DIY Home Kits | Professional Whitening |
|---|---|---|
| Cost | £6 – £120 | £200 – £900+ |
| Strength of gel | Low peroxide levels (limited by law) | Stronger, dentist-regulated formulas |
| Results | Mild, gradual changes | Brighter, more predictable whitening |
| How long do results last | Weeks to a few months | One to three years, depending on care |
| Fit and comfort | One-size trays or strips | Custom-made trays for even coverage |
| Safety | Risk of irritation if misused | Monitored by a dental professional |
| Best for | Light staining and short-term brightening | Deeper stains and long-term improvement |
DIY kits rely on weaker gels because only dentists can legally use higher-strength whitening agents. This means the colour change is often subtle, and stains can return sooner. The trays and strips included in retail kits also tend to fit loosely, so the gel may not cover all teeth evenly.
Professional whitening is custom-made for your teeth. A dentist can adjust gel strength, manage sensitivity, and make sure each tooth lightens consistently. This gives better results that last much longer.
DIY kits can help if you only want a small lift in shade or a quick, inexpensive touch-up. If your goal is a noticeably brighter smile that lasts, professional whitening offers far more value and predictability. With a dentist overseeing your treatment, you’ll also avoid the risks that are connected to poorly fitting trays or unregulated products sold online.
Where you go affects the cost of teeth whitening. Clinics in major cities, especially London, often charge more due to higher overheads and demand. Regional clinics usually offer the same treatments at lower prices, making professional whitening more accessible outside the capital.
Regional differences to consider:
Tips for choosing a clinic:
| Region | Typical Cost Range (In-Clinic Whitening) | Notes |
|---|---|---|
| London | £600 – £1,000 | Premium pricing often includes top brands |
| Southeast (outside London) | £400 – £800 | Slightly lower than central London |
| Midlands | £300 – £700 | Competitive local pricing |
| North of England | £250 – £650 | Affordable, with similar results |
| Scotland / Wales / Northern Ireland | £250 – £600 | Generally, the lowest UK rates |
Teeth whitening in the UK is regulated to keep treatments safe. Only registered dental professionals can use high-strength gels. Over-the-counter products must contain no more than 6% hydrogen peroxide.
What this means for you:
Following these rules reduces the risk of sensitivity, uneven results, or damage to enamel. Choosing a qualified dentist ensures a safer, more predictable outcome.
Most adults with healthy teeth and gums can safely whiten their teeth. However, whitening may not be suitable if you have:
Your dentist will assess your oral health before treatment. In some cases, you may need cleaning, fillings, or polishing first to achieve the best results. If you have sensitive teeth, your dentist can adjust the gel strength or recommend a gradual approach.
Tip: Be honest about your dental history and habits. Your dentist can recommend the safest and most effective whitening method for your smile.

Teeth whitening is considered a cosmetic procedure in the UK, so it is not usually covered by the NHS. The only exception is when whitening is needed for clinical reasons, such as treating a single discoloured tooth after root canal therapy.
For all cosmetic whitening, you must arrange treatment privately. Before booking, ask your dentist for a written quote and confirm exactly what is included. Things like trays, gels, and follow-up visits can be a separate expense. Knowing this upfront helps you avoid unexpected costs.
The results of professional whitening can last one to three years, depending on your lifestyle. Good oral hygiene and regular dental visits are the simplest ways to maintain your results. To keep your smile bright:
