Terms and conditions
Last updated: November 2026
1. About us
Stretton Mathematics is run by Mr Johnston, a qualified, DBS-checked mathematics teacher, trading as a sole trader in England. You can contact us at strettonmathematics@gmail.com. In these terms, “we” and “us” means Stretton Mathematics, and “you” means the parent or carer booking for a student, or an adult learner booking for themselves.
2. The programme
Each programme lasts twelve teaching weeks and includes:
- a diagnostic assessment before joining, marked by us, with the results discussed on a short call or by email;
- placement in a small group of no more than eight students working at a similar standard;
- 24 live online lessons of one hour each, two a week, at the days and time confirmed when you enrol;
- homework help, and a catch-up for any lesson the student misses;
- a progress assessment in week 12 and a written summary of the results.
Lessons pause for one week from Monday 21 December. Any group running over Christmas finishes a week later, so every student receives all 24 lessons.
3. Groups and placement
We place students using the diagnostic assessment. If, during the first two weeks, we believe a student would be better suited to a different group, we will discuss a move with you. New groups open every fortnight as places allow. If a group cannot run, we will offer another start date or a full refund.
4. Fees and payment
The fee for one programme is £480. You can pay in full before the first lesson, or in three monthly payments of £160, with the first payment due before the first lesson. If a payment is more than 7 days late, we may pause lessons until it is paid.
5. Cancellations and refunds
You have the right to cancel within 14 days of booking without giving a reason. If you ask for lessons to start within those 14 days and then cancel, we will refund the fee minus the cost of lessons already delivered (£20 per lesson).
After the 14-day period, you can cancel by giving us 7 days’ notice in writing. We will refund the cost of any lessons not yet delivered at that point (£20 per lesson). Lessons a student misses are not refunded, but a catch-up is always available.
If we have to cancel a lesson, we will rearrange it or provide a catch-up. If we cancel a programme, you will receive a full refund for any lessons not delivered.
6. The progress guarantee
If a student’s week 12 progress assessment score is not higher than their diagnostic assessment score, they can join the next twelve-week programme at the same level free of charge, provided that:
- they attended at least 20 of the 24 lessons, including catch-ups;
- they completed the independent practice set in lessons;
- they sat both the diagnostic and the week 12 progress assessments;
- you claim within 30 days of the week 12 assessment.
The free place is subject to availability, is limited to one per student and has no cash alternative.
7. Homework help
Students in a current group can send homework questions throughout their programme. Students who are not enrolled can send one free question. We aim to reply with a worked solution within 24 hours. Homework help explains methods and gives worked solutions to support learning. It is not for completing coursework or assessed work on a student’s behalf.
8. Behaviour in lessons
We expect every student to be respectful to the teacher and to other students. If a student’s behaviour disrupts lessons, we will speak to you first. If it continues, we may remove the student from the group, and any refund will be at our discretion.
9. Free resources
Our worked examples, cheat sheets, videos and diagnostic papers are free for personal, non-commercial use. They remain our copyright and must not be sold or republished without permission.
10. Our responsibilities
We will teach every lesson with reasonable care and skill. Progress depends on many things, including attendance and effort, so we cannot guarantee a particular exam grade. Nothing in these terms limits your rights as a consumer under UK law.
11. Referrals
If a family you refer enrols and pays for a programme, we will take £50 off your next programme for each one. Credit has no cash value, cannot be exchanged, and is applied to the next programme you book.
12. Changes and law
We may update these terms. Any change will not affect a programme you have already booked. These terms are governed by the law of England and Wales.
