The verdict in three sentences
A group of 7 care homes with 650 care staff still running rotas on spreadsheets pays for the chaos mainly through last-minute agency shifts, often 30 to 60 % dearer than an internal hour. A custom rota web app costs between GBP 40,000 and 80,000, over 4 to 5 months, and encodes the Working Time Regulations plus your own contractual rules on breaks, nights and weekend rotation. With a shift marketplace open to bank staff and willing permanent carers, cutting agency spend by 15 to 25 % is a realistic first-year target.
Why generic rota tools struggle in care homes
Generic tools handle office hours well. In adult social care the constraints are different: 6 to 12 week rotating patterns, 12-hour shifts, nights, alternate weekends, staffing levels to maintain on every shift as expected by the CQC, and skills (nurses, senior carers, carers, domestic staff) that are not interchangeable.
The HR director of a London group wants four things in practice:
- Rotas generated automatically, compliant with 11-hour daily rest and the 48-hour weekly average.
- Absences reported from the phone, with the gap visible in the rota immediately.
- Cover offered first to willing permanent staff, then to the bank pool, and only then to the agency.
- Payroll export of actual hours, including night and weekend enhancements.
| Criterion | Generic rota software | Custom app |
|---|---|---|
| Working time and contractual rules | Partial configuration, manual checks | Coded and checked on every change |
| 12-week rotating patterns | Often limited | Dedicated generator per home |
| Skills and staffing levels per shift | Rarely handled | Alert when a shift drops below the threshold |
| Shift marketplace for bank staff | Missing or third-party module | Built in, mobile notification in seconds |
| Payroll export | Generic file | Exact format of your payroll |
| Data protection | Varies by vendor | UK GDPR aligned, DSPT friendly hosting |
| Entry cost (2026 order of magnitude) | GBP 3 to 8 per staff member per month | GBP 40,000 to 80,000 once |
Detailed budget and running costs
The GBP 40,000 to 80,000 range depends mostly on three variables: rule complexity, the number of integrations (payroll, time clock, care planning system) and how rich the mobile app is.
| Item (2026 order of magnitude) | Essential version | Full version |
|---|---|---|
| Scoping, workshops with home managers | GBP 4,500 | GBP 8,000 |
| Rota engine and working rules | GBP 16,000 | GBP 28,500 |
| Mobile app for staff | GBP 8,000 | GBP 16,000 |
| Shift marketplace and bank staff | GBP 5,500 | GBP 11,500 |
| Payroll and time clock integrations | GBP 3,500 | GBP 10,500 |
| Testing, training, rollout to 7 homes | GBP 2,500 | GBP 5,500 |
| Project total | GBP 40,000 | GBP 80,000 |
| UK hosting | GBP 180 per month | GBP 350 per month |
Add maintenance, typically 15 to 20 % of the build cost per year, to keep up with contract changes and security updates.
A 4 to 5 month timeline
Month one formalises the rules: every home has its own habits, and writing them down prevents months of corrections. Months two and three deliver the rota engine and mobile app. Month four is a pilot in one home over two real rota cycles. Month five rolls out to the other 6 homes, two per week, with half a day of training per management team.
Mini case study
Sarah Okafor, HR director of a group of 7 care homes across north London, spends GBP 950,000 a year on agency staff for 650 carers and nurses. Analysis shows 60 % of agency shifts are booked less than 48 hours ahead, because nobody sees which permanent staff would pick up extra hours.

With the shift marketplace, each absence triggers a notification to 120 willing staff and a bank pool of 80. If 20 % of agency shifts are filled internally or by bank staff, savings reach GBP 190,000 a year. Extra overtime enhancements cost about GBP 60,000, leaving a net gain of GBP 130,000.
The full build costs GBP 70,000, plus GBP 4,200 of hosting and GBP 12,000 of maintenance in year one. Payback arrives in under 8 months, not counting freed management time, estimated at 6 hours a week per home.
FAQ
Which hosting and compliance standards apply?
If the app touches resident data or staff sickness records, choose UK hosting aligned with UK GDPR and the Data Security and Protection Toolkit your homes already complete. Budget GBP 180 to 350 a month for an app this size.
How does the tool follow changes to contracts or rules?
Rules are stored as parameters (durations, rest, enhancements). A change usually means 1 to 3 days of updates, covered by the maintenance contract.
Do bank staff have to install an app?
No, an installable web app is enough. They get a notification, accept the shift in two taps, and the rota updates in under a minute.
Can we import existing rotas?
Yes. Current patterns are imported from your spreadsheets during scoping, which takes 3 to 5 days for 7 homes.
Custom build or specialist vendor?
Below 200 staff, a care-sector vendor at GBP 3 to 8 per staff member per month is often enough. Above that, with several contract types and a shift marketplace, custom becomes competitive by year three.
