What the work actually looks like, week by week
A typical mid-experience science tutor on the platform — say a working secondary teacher with two years of QTS — runs around 8–12 hours a week of tutoring on top of school. Mondays and Tuesdays light, Wednesday off, Thursday/Friday evening filled, Saturday morning the busiest slot of the week (90% of tutors are full Saturday 9–12 by November). One client per slot, weekly, hour-long, online.
The session structure that wins repeat bookings: arrive on the call two minutes early, marked homework already in the shared whiteboard, three minutes of how-was-school, then straight into past-paper-question work. Forty minutes of the hour is the kid working with the tutor prompting. Ten minutes of recap and homework setting. After the call, send a one-line message to the parent: what was covered, what’s next. That message is the difference between a 6-week booking and a 30-week booking.
What stops it being easy:
- November to March is the busy run; April–July is the GCSE/A-Level cliff
- August is dead unless you do 11+ summer prep
- A bad first session loses you the client by Tuesday morning, so Mondays at 8am are when most cancellations land
- One genuinely difficult parent can eat 4 hours of unpaid messaging a month
The rate-setting mistake that kills earnings
The most common mistake new science tutors make: setting £20–£25/hr to “get started” and then being unable to raise it later. Once a parent has anchored at £25, they will leave you for someone at £25 elsewhere rather than pay you £35. Far better to start at £35–£40, take fewer enquiries in the first month, and build a roster of clients paying the rate you actually want.
Three rate-anchors that work:
- “Currently full at this rate, but I have one Tuesday 7pm slot opening on the 14th” — scarcity language, true scarcity
- A profile that lists specialism (AQA Biology Triple, dissection diagrams, photosynthesis required practical) rather than generic “Science tutor”
- Real outcomes named: “Last summer 7/8 GCSE Biology students achieved their target grade or above, including one 4→7”
The other earnings killer is taking on enquiries you can’t deliver. A Chemistry teacher who agrees to “a bit of Physics for the same student” loses time prepping unfamiliar material and underdelivers. Pass it on. The platform doesn’t penalise you for declining — it penalises you for slow replies and cancelled sessions.
A working teacher’s path from £0 to £18k a side income
Real example, anonymised. Secondary biology teacher in Leeds, 4 years post-QTS, joined the platform in September. First month: 2 enquiries, 1 booked at £35/hr. Adjusted profile in week 4 — added board specialism, two student outcomes, a working DBS scan. Month two: 9 enquiries, 5 booked. By February: 11 weekly clients at £40/hr, mostly online, mostly GCSE Biology with two A-Level. Net of platform fee, that’s £418/week. Across 32 teaching weeks of the year (he doesn’t work the holidays), that’s £13,376. Add some intensive Easter and August half-term blocks and he was at £18k for the year.
The key moves: he set his rate honestly, he replied inside 30 minutes during weekday evenings, and he kept his hourly load below 12 a week so he wasn’t burning out his day job. He turned down 4–5 enquiries a month for subjects outside his lane.
How to apply, and the trial-call discipline
Sign up at TheTutorLink, fill the profile (real name, real photo, board specialisms, hourly rate, availability calendar), upload a DBS if you have one, and turn notifications on. Enquiries arrive by message; you reply, agree a free 20-minute trial call, run it, and if the family books, your first session is paid through the platform with our 5% deducted. The trial call is non-negotiable on TheTutorLink — every tutor offers one.
The free-trial discipline matters: don’t teach in the trial. Diagnose. Ask the student to attempt one past-paper question while you watch, identify the actual gap, and tell the parent honestly how many sessions you think it’ll take. Parents don’t book the tutor who promises the most. They book the one who sounds like they know what’s wrong. Set your rate, hold it, keep 95% of it. That’s the model.
