Membership of the Society falls into eight categories:
- Ordinary membership; for academic staff, mathematicians in other occupations and all those with a deep commitment to mathematics and an interest in mathematical research.
- Advanced Post-doc membership; for those who have completed their PhD within the last three to six years, excluding career breaks.
- Retired membership; for those who have retired from their professional careers.
- Reciprocity membership; for those not normally resident in the UK and who are also members of an overseas mathematical society, with which the LMS has a Reciprocity Agreement.
- Worldwide Access membership; for those who are based in countries listed in the IMU developing countries classification:
- Worldwide Access (Reciprocity) membership; for those who are based in countries listed in the IMU developing countries classification and who are also members of an overseas mathematical society, with which the LMS has a Reciprocity Agreement.
- Associate membership; for postgraduates and early career mathematicians who are within three years of completing their PhD.
- Associate (Undergraduate) membership; for undergraduates studying for degrees in mathematical sciences.
Further details of each category are given below.

Tiered Ordinary Membership rates for current and new members
The Society offers three tiers of Ordinary membership rates and members who pay the Ordinary membership rate can confirm online which membership rate they wish to pay based on whether their annual professional income falls within the following ranges:
- Above £70,000 per annum: Ordinary (high) member rate.
- Between £40,000-£70,000 per annum: Ordinary (middle) member rate.
- Up to £40,000 per annum: Ordinary (low) member rate
The Society will not collect any data on members’ actual professional income nor require proof of earnings. Instead, Ordinary members are asked to advise either via their online member record or the subscription form which tier of Ordinary membership subscription they will be paying. For members who pay by direct debit, we encourage you to update this information by 14 October 2026.
The Society offers a pro-rata of the full membership rate to new members based on their date of election to membership during the Membership Session, as shown below:

Please note that the default subscription fee for all new Ordinary members will be Ordinary (Middle) member rate so members are asked to advise us of any changes at your earliest convenience. All members can amend their tier type via either their online member record or by completing and returning the subscription form.
Ordinary Membership is available to:
- Academic staff of a university or similar institution in the United Kingdom who are substantially engaged in teaching and research in mathematics (including all its diverse applications).
- Mathematicians in other occupations, whether or not they are currently employed, who have a higher degree in mathematics, or who use mathematics in their work at a comparable level, or whose work would benefit substantially from the Society's activities in promoting and extending mathematical knowledge.
- All those with a deep commitment to mathematics and an interest in mathematical research.
- Others whom Council considers to have contributed substantially to the objects of the Society.
Advanced Post-doc Membership is available to:
- Mathematicians who are in a postdoctoral stage and are between three and six years from obtaining their PhD in mathematics, full-time equivalent and excluding any recognised career breaks.
- Current Associate Members whose Associate membership is ending after three years since PhD completion and who are eligible to move to the Advanced Post-doc rate for a further three years before moving to Ordinary membership.
- Current Ordinary Members, or other current members, who are in a postdoctoral stage and completed their PhD between three and six years ago, excluding any recognised career breaks, and who may be eligible to move to the lower Advanced Post-doc rate.
Advanced Post-doc membership is available for a maximum of three years. After this period, members will be upgraded to Ordinary membership.
Retired Membership is available to:
- Members and applicants who would otherwise be eligible for Ordinary Membership but have now reached retirement age or retired from their career.
Reciprocity Membership is available to:
- Members of some overseas Mathematical Societies who are not normally resident in the UK. They may join under the terms of various Reciprocity Agreements, although Council reserves the right to consider each application individually.
The organisations with whom the Society has agreements are:
Any mathematical society not appearing on the above list interested in entering into a reciprocity agreement should write to membership@lms.ac.uk.
Worldwide Access Membership is available to:
- Mathematicians at any stage of their career who are normally resident in countries listed in the IMU CDC classification of developing countries.
- Applicants and current members who meet this residency requirement and wish to join or continue their LMS membership at the Worldwide Access rate.
Worldwide Access (Reciprocity) Membership is available to:
- Mathematicians at any stage of their career who are normally resident in countries listed in the IMU CDC classification of developing countries and who are also members of overseas mathematical societies with which the LMS has Reciprocity Agreements.
- Applicants and current members who meet both the residency requirement and the relevant reciprocity requirement.
Associate Membership is available to:
- Early career mathematicians who are within three years of obtaining their PhD in mathematics (full-time equivalent and excluding any career breaks)
- Research students who are studying for a PhD in mathematics.
- Research students who are studying for a MSc in mathematics or a Masters degree with a significant mathematical content.
Associate (Undergraduate) Membership is available to:
- Undergraduate students who are studying for a degree in mathematics or a degree with a significant mathematical content.
Council also has the authority to elect Honorary Members from distinguished mathematicians who are not normally resident within the United Kingdom.
