Membership terms and conditions

This page sets out the Terms and Conditions of Membership (“Terms”) of the British Lingual Orthodontic Society (“BLOS/us/our”) and applies to the provision by us of any of our Membership Services (“Services”) to our Members (“Members/you/your”) or visitors to our Website and sets out our commercial relationship with you.

The Terms are an agreement between BLOS and any members and constitute a legal agreement. Please read them in conjunction with our Website Disclaimer, Privacy Policy and Cookies Policy, all of which can be found at (“Website”). If you do not agree with these Terms or wish to be bound by these, please stop using the Website immediately.

Please note that our Website does not provide any dental advice and is purely a directory and membership organisation for lingual orthodontics.

These Terms are subject to change from time to time to comply with changes to the law, regulatory requirements, or for business purposes. The latest version of these terms and conditions will be available here and we may also email these to you.

Who are we?

We are the British Lingual Orthodontic Society (BLOS) and our trading office is c/o The British Orthodontic Society, 12 Bridewell Place, London EC4V 6AP.

Access to and use of our website

Access to our Website is free of charge and it is your responsibility to make any and all arrangements to access our Website. Access to our Website is provided “as is” and on an “as available” basis. We may alter, suspend or discontinue our Website (or any part of it) at any time and without notice. We will not be liable to you in any way if our Website (or any part of it) is unavailable at any time and for any period.

Registration, application for membership, and membership

You may apply to become a member of BLOS by completing the forms on the Website (“Registration Form”) and agreeing in that Registration Form to these Terms.

No part of our Website constitutes a contractual offer capable of acceptance. Your application to us constitutes a contractual offer that we may, at our sole discretion, accept. Our acknowledgement of receipt of your application does not mean that we have accepted it. Our acceptance is indicated by us sending you a confirmation by email that your application has been accepted.

You agree to provide us with accurate information in the Registration Form and to accept these Terms on submission of the Registration Form with us.

Upon our confirmation of your membership, your payment of the Membership Fee and the instruction of your Direct Debit, there will be a contract between you and us on these Terms and your Membership will be formed (“Membership”). Our acceptance of these Terms is conditional upon your agreement to these Terms in full which you will formally accept upon completion of your Membership application.

BLOS’s Membership packages and Membership benefits are listed on the Website.

In addition to the Membership Fees that are applicable, you will be required to pay an initial joining fee of £75 if you subscribe to a full Membership. This fee also applies to Members who leave and rejoin BLOS and these fees are renewable every March.

The Membership year runs from March to February and depending on when you join BLOS, the Membership will only run to February in the membership year that you join.

General membership

You may not transfer any rights associated with your Membership or the rights and obligations under these Terms to anyone else, or any other organisation.

We reserve the right to change any benefits that go with your Membership at any time, and without prior notice.

We reserve the right to expel you from BLOS and/or to withdraw or refuse to renew your Membership, or suspend it for a specific period, if your conduct is in our reasonable opinion unacceptable, or is or may be in our reasonable opinion, harmful to the reputation of BLOS, or if it amounts to your breach of these Terms, or where in our reasonable opinion such expulsion, withdrawal or refusal to renew your Membership, is otherwise in the interests of the other Members. If we expel you, you will then cease to be a Member of BLOS. You will not be entitled to any refund of any part of your Membership Fee for any withdrawn or suspended period of Membership due to expulsion or to suspension of your Membership.

Membership fees

By agreeing to these Terms, you agree that you will pay to us the applicable Membership Fee for all Services that we provide to you and you may pay by the following methods:

  • Bank transfer (new Members)
  • Direct Debit

Details of our Memberships Fees can be found on our Website, or you may contact us directly.

Your first payment will be payable according to our Membership fees including the joining fee if appropriate, and any subsequent future renewal payments will be due the following February at the applicable Membership Fee.

Your first payment should be made via bank transfer. All renewal payments should be made via Direct Debit.

Your membership will commence only once we have received your completed Direct Debit mandate by post.

Any overpayments will be refunded but subject to a small administrative fee of £50 which will be deducted in advance.

Shortly before your Membership renews, we will email you to notify you that your renewal payment is due.

Please note that any Direct Debit payments to us will be processed via the British Orthodontic Society on our behalf.

Members will be entitled to BLOS Membership services on either a full basis or student rate. For more information as to what is and what is not included at each level, please see the Website. Please note that you will only be entitled to the benefits of the membership subscription you have chosen.

If you wish to upgrade your Membership at any time, you may do so by notifying us in writing and you will be required to pay the remaining balance calculated as the difference between revised and previously charged Membership Fee and will be required to commit to the end of the existing Membership year from the date of the upgrade.

All sums not paid by you will be subject to interest at 8% per annum above the Bank of England base rate until such a time as payment is made.
We reserve the right to increase our Membership Fees as appropriate but certainly on an annual basis.

Term and renewal

The Membership year runs from March to February. Your Membership will be valid for the remainder of the Membership year i.e. until the following February and will continue to renew automatically for the next term of 12 months and you will be responsible for the new Membership Fees, unless you provide us with notification in writing (by email) that you wish to cancel your Membership.

Cancelling your membership

Your Membership will continue until we receive written notification from you in writing (by email) giving us notice to terminate, or if a renewal payment or any other payments due under these Terms are not received.

Once payment for Membership has been taken, we cannot issue any refunds to you. However, on notice to terminate, any future payments will be cancelled, and your Membership benefits will remain in place for the remainder of the Membership year.

Use of the BLOS logo is a Membership benefit and it is your responsibility to remove the logo from your website(s), emails and printed materials by the end of the Membership year.

BLOS shall be entitled to terminate your Membership with immediate effect at any time, in the event that you fail to make a payment due or do anything that would result in a material breach of these Terms.
