Pricing FAQs

The SmileBox™ price of £42 contains everything you need to make a total of 6 dental impressions: 3 of your upper arch and 3 of your lower arch. It also includes free return shipping, your 3D smile simulation video and comprehensive Straight Teeth Plan, which comprises a detailed orthodontic analysis of your current dental structure, a prediction of your future smile, as well as the movements necessary to achieve those goals and your results agreement. This stage is to make sure you are 100% happy with the results before you commit further and is also covered by our unique Suitability & Impressions Guarantee (see Guarantees for more info). This step does not yet cover the aligner cost, which is detailed below.

The StraightBox™ price of £1.350 covers the aligner cost and contains everything you need to achieve the smile goals outlined and agreed upon in your orthodontic plan, with no hidden costs. This means: all necessary invisible aligners (incl. refinements if required), continued support and monitoring by our support and clinical teams and free shipping. This stage is also covered by our unique Lost & Broken Aligner Replacement Guarantee, meaning you receive replacement aligners in case of loss or breakage at no extra charge, as well as our Results Agreement Guarantee, so that you can be 100% sure that you will receive everything your smile requires to achieve the results agreed upon (see Guarantees for more info).

We do have offers on the teeth whitening upgrades. We have optimised remote orthodontic treatment in such a way that allows us to provide the highest quality results at the lowest possible aligner cost all year round.

The teeth straightening treatment is £1,350 if you pay in one go.

You have the option to choose from 2 in house, credit check free payment plans:

  • Monthly payments: £399 upfront then £150 monthly for 8 months
  • Three instalments: £500 upfront then £500 2 months later and another 2 months later

Or opt for an external finance provider for longer repayment periods:

  1. Buy now pay later with Humm – £125 per month over 12 months
  2. Multi-lender platform referral offering personalised options based on your chosen repayment period.

Both finance options require an online credit application and approval process. Terms and conditions apply with both options and are handled externally with your chosen provider.

With our unique in-house payment plans you can spread the cost of treatment independently of your income or financial situation and it won’t impact your credit history since it is set up as a subscription directly with us.

Since we take the financial risk and you receive part of the treatment upfront, we have built the payment plans to work for both you and us without having to delay your treatment or make huge deposits.

For this reason, you technically receive a discount for paying the aligner cost quicker or in full.

External finance plans may be subject to interest depending on your chosen provider.

Your payment plan is automatically set up at check out, and payments are handled for you automatically by Stripe (the app payment processor) on a monthly basis in accordance with your first transaction. The payments for the aligner cost are NOT synced with the progress of your treatment.
For example, if you made the first payment on January 1st, your next payment will be due exactly one month from then, so on February 1st and so on. The payments will be subtracted directly from the card you registered with.

Don’t worry, the payment processor will try to subtract the amount 3 times. If after the 3rd try payment is still unsuccessful, you will be contacted to solve the issue.

Everyone is eligible for our 2 in house plans (monthly / 3 instalments).
External UK finance providers require a credit check on application.

If you’re a UK resident over 18 years old and employed with a regular income, you can apply for finance.
You can choose to apply directly online with Humm for the buy now later plan, or we can refer you to a multi-lender platform.
With both options, your application will be made online and your income and credit score will be assessed before receiving a decision instantly.
If you choose the multi-lender platform, you will be provided with loan options by multiple brokers.
If you accept one of those provided options, you will receive an agreed lump sum in which you can use to pay for your aligner treatment.

The finance application is all done online through a credit provider once you have received and e-signed your results agreement.
For the buy now pay later option you will first verify your eligibility with them and then be able to proceed with setting up the plan should you be approved.
With the multi lender platform it works with no upfront aligner cost and you can choose to pay over 1 to 5 years.
Please note that rates provided on the multi-lender platform are for guidance only and are calculated by the finance company. They are based on your personal financial circumstances and credit score at the time of application.
To give you an idea, for someone with a good credit rating you could choose plans from £40/month x 36 months (based on 3.2% APR).

We work with registered providers, Humm and a multi-lender finance platform where we act as introducers. Straight Teeth Direct™ is in no way involved in the borrowing and repayment procedures.
– If you apply through Humm, you can select the fixed repayment plan of £125 per month over 12 months. When you submit your application a hard credit search will be performed based on your personal financial situation and you will receive a decision instantly.
Once accepted the terms and conditions are agreed when the first payment of £125 is paid. You will also get access to a dedicated Humm account where you can manage your payment plan, change your card details, and update your payment date.
– If you apply through the multi-lender platform, they will first provide you with options from different brokers based on your financial situation. You can proceed to choose which option you prefer and obtain a quote directly through your chosen broker. This quote and the repayment options depend on your financial circumstances, credit score, and how much you wish to borrow. Your credit score will not be affected by this loan until you accept one of the offers.

Once you receive your aligner treatment plan, you can let us know that you’re interested in applying for finance. Then, we will be able to refer you to our finance partners and you will receive an online application link in your email inbox. Follow the link to fill out the short form. You will need to specify how much you want to borrow, over which period of time (1 to 5 years), as well as some information about yourself. You will then be given several loan options available to you based on the information entered. If you agree to the rates and conditions offered and take out a loan, the respective broker then releases the money to you. Using this money, you can then place your order your aligner treatment via the app.

If you have applied through Humm, you can then simply checkout through the app and select the Humm option on the checkout screen. This will direct you to login to your Humm profile where you can make your first payment. We will then confirm your StraightBox order via a message in the app.
If you have applied through the multi-lender platform, you will need to wait to receive the funds from your chosen provider into your normal bank account, and once received you can proceed to checkout through the app.

With Humm the plan is fixed to £1,500 at a payback rate of £125 per month over 12 months.
With the multi-lender platform you can apply for loans from £500 to £1,500, with no upfront cost and with repayment durations of 1 to 5 years. The credit company you choose to apply with will inform you of the rate they can offer based on your financial circumstances and credit score. These will vary individually and Straight Teeth Direct™ cannot influence this and does not have access to this information for your own data privacy.

If your application is declined or you aren’t happy with the interest rates provided, you’ll have the option to choose one of the in house credit check free plans instead. VIEW PAYMENT PLANS
