The cost of professional teeth whitening in London varies widely — from under £200 to over £800 — depending on the type of treatment, the clinic, and what's included. This guide breaks down current London pricing, explains what influences cost, and shares how our Teeth Whitening clinic provides professional home whitening from just £199.
What Determines the Price of Teeth Whitening in London?
In the UK, teeth whitening is classified as a dental procedure. It must be carried out or prescribed by a registered dental professional — a requirement set by the General Dental Council (GDC). The cost of professional whitening typically reflects several factors:
1. The Initial Clinical Assessment
Before any whitening treatment can begin, a full clinical examination is required. This is a CQC and GDC regulatory requirement, not an optional extra. Your dentist will check for underlying issues such as decay, gum disease, or exposed root surfaces that must be addressed before whitening is safe to proceed. This assessment protects your oral health and ensures you're a suitable candidate.
2. Customisation of Whitening Trays
Professional home whitening involves laboratory-made trays tailored to your unique dental anatomy. These custom-fitted trays ensure even gel distribution across all tooth surfaces, protect your gums from unnecessary gel contact, and provide a comfortable fit for daily wear. The cost of dental impressions, lab fabrication, and quality materials is reflected in the overall price.
3. The Whitening System and Gel
Professional whitening gels contain up to 6% hydrogen peroxide — the maximum concentration permitted for dental use in the UK. This is approximately 60 times more concentrated than the 0.1% maximum allowed in shop-bought products. Premium whitening systems from established dental brands often carry a higher price due to research, formulation quality, and desensitising agents included in the gel.
4. Professional Supervision and Follow-Up
The cost also covers ongoing professional oversight — including treatment instructions, monitoring progress, and follow-up appointments to assess your results. This level of care distinguishes professional whitening from unsupervised over-the-counter products.
Representative Teeth Whitening Costs in London (2026)
While prices vary between clinics, here is a general overview of what you can expect to pay for professional teeth whitening across Central London in 2026:
Professional Home Whitening Kits
A dentist-prescribed home whitening kit in London typically starts from approximately £350 to £500. This usually includes a consultation, custom trays, and a course of professional-grade whitening gel. At our South Kensington clinic, we offer this complete package from just £199 — including consultation, custom-fitted trays, a full course of professional gel, and a follow-up review.
In-Chair (Laser/Power) Whitening
In-office whitening treatments, where a higher-concentration gel is activated by a light or laser in the dental chair, typically range from £400 to £800 in London. These treatments offer immediate results in a single appointment but may carry a higher risk of temporary sensitivity due to the more intense application.
Combination Treatments
Some clinics offer combination packages — an in-chair session followed by take-home trays for maintenance — which may range from £550 to £850. These packages aim to provide both immediate results and longer-term maintenance.
Why Our Pricing Starts From £199
Teeth whitening is one of the most popular procedures at our South Kensington clinic. We carry out a high volume of whitening treatments, which allows us to offer professional-grade results at a price point that is accessible for more patients — without compromising on quality, safety, or professional oversight.
Our £199 complete whitening package includes everything you need:
- Professional consultation and clinical assessment — suitability confirmed by a GDC-registered dentist
- Custom-fitted whitening trays — made from precise impressions of your teeth
- Full course of professional-grade whitening gel — 6% hydrogen peroxide, the maximum UK-permitted concentration
- Detailed usage instructions — tailored to your individual needs
- Follow-up review and top-up gel — to assess your results and provide maintenance support
There are no hidden costs. The price you see is the price you pay.
Affordable gel refills are also available from £35, so you can maintain your results long-term using the same custom trays — making the initial investment even better value over time.

What to Watch Out for When Comparing Prices
When researching teeth whitening costs in London, it's important to understand exactly what's included in the quoted price. Some things to consider:
- Is the consultation included? Some clinics charge separately for the initial assessment, which can add £50–£100 to the total cost
- Are custom trays included? Generic or "boil-and-bite" trays are cheaper but don't provide the same even gel distribution or gum protection as custom-fitted trays
- How much gel is provided? Some packages include only a limited supply, requiring you to purchase additional syringes at extra cost
- Is follow-up care included? A post-treatment review is important to assess your results and address any concerns
- Is the clinic CQC-registered? All dental practices in England must be registered with the Care Quality Commission. This ensures regulatory oversight and patient safety standards
Is Cheaper Whitening Worth the Risk?
It can be tempting to opt for the lowest price — but with teeth whitening, the cheapest option may not be the safest or most effective. Beauty salon whitening and unregulated online kits pose genuine risks:
- Beauty salon whitening is not legally permitted in the UK unless carried out by or under the prescription of a registered dental professional
- Over-the-counter products are limited to 0.1% hydrogen peroxide by law — a concentration that may produce only minimal results over an extended period
- Unregulated products purchased online may contain undisclosed concentrations of peroxide or other harmful ingredients
Professional whitening at a CQC-registered clinic ensures your treatment is carried out safely, using UK-approved products at appropriate concentrations, with proper dental assessment and oversight.
