The verdict in three sentences
A private school head is not after a better spreadsheet: they want a single system linking admissions, academic records, marks, finance and family communication. In 2026, a market solution costs GBP 3 to 8 per pupil per year, while a custom build lands between GBP 45 000 and 115 000, delivered in 4 to 7 months with a parent portal. The switch is decided on pupil volume, the specificity of your pathways and the need for a branded portal.
The modules that truly matter
A school system is judged on the full journey: from application to tuition payment, through to reports and the family relationship. Here is the expected coverage and its 2026 order of magnitude.
| Module | Key function | Market price (GBP/pupil/yr) | Custom build (GBP) |
|---|---|---|---|
| Admissions | Applications, files, decisions | 1-2 | 9 000-22 000 |
| Records & marks | Timetables, marks, reports | 1.5-3 | 13 000-31 000 |
| Finance & payments | Tuition billing, reminders | 1-2 | 10 000-26 000 |
| Parent & pupil portal | Tracking, messaging, documents | 0.5-1.5 | 9 000-22 000 |
| Reporting & compliance | Rolls, rates, dashboards | included | 7 000-18 000 |
Added up, the custom column fits the GBP 45 000-115 000 range depending on scope.
What each route costs over 4 years
For a 900-pupil school, a market solution at GBP 6/pupil/yr costs GBP 5 400/year, i.e. GBP 21 600 over 4 years. The custom build is a one-off investment amortized over the system's life (often 6-8 years).
| Criterion | Market solution | Custom Kolonell build |
|---|---|---|
| 4-year cost (900 pupils) | ~GBP 21 600-28 800 | GBP 45 000-115 000 once |
| Time to deploy | 2-6 weeks | 4-7 months |
| Branded portal | rarely | yes, fully |
| Bespoke admission pathways | standardized | tailored |
| Pupil data ownership | vendor | school |
Mini case study
Take Mrs. Hughes, bursar of a 720-pupil independent school in Surrey. Before the project, admissions tied up 2 full-time staff at peak and tuition reminders were manual: 4% late arrears on average fees of GBP 14 000/year. Kolonell delivered a custom platform at GBP 82 000 in 6 months, with automated reminders and a parent portal. Result: late arrears down to 1.3%, i.e. 2.7 points recovered on ~GBP 10M of fees = ~GBP 270 000 of cash secured earlier, and 1.5 admin FTE redeployed. Investment recouped within the first cycle year.

How much does school management software cost in 2026?
With a market solution, budget GBP 3 to 8 per pupil per year; for 900 pupils that is GBP 2 700 to 7 200/year. Custom, the investment lands between GBP 45 000 and 115 000 once.
Is the parent portal included?
In a market solution it is often a paid add-on. Custom, the parent and pupil portal is built to your brand, with messaging, marks tracking and online payments.
Can we handle bespoke admission pathways?
Yes with custom: entrance exams, interviews, waiting lists, bursaries. Market solutions often impose a standardized workflow less suited to selective schools.
What is the deployment timeline?
Budget 4 to 7 months for a full custom build, starting with a pilot cohort before rolling out at the next intake.
Is pupil data GDPR-compliant?
A custom project bakes in GDPR by design (minimization, consent, EU hosting) — critical for minors' data.
