The verdict in three sentences
For a cleaning contractor with 280 operatives across 150 sites in London, custom software covering scheduling, geolocated mobile clock-in and quality audits costs 50,000 to 100,000 GBP in 2026. The fastest gain comes from unverified hours: 1 to 2 % of payroll recovered, or 65,000 to 130,000 GBP a year on a 6.5 million GBP payroll. The project typically pays back within 6 to 12 months, before counting the contracts you keep thanks to documented quality checks.
Where the hours go in a cleaning company
The operations director of a 280-operative business juggles Excel rotas, paper timesheets signed on site and cover arranged by text message. Across 150 sites, every unplanned absence, unapproved overtime hour and unchecked shift eventually costs money, either in payroll or in client penalties.
| Source of loss (2026 estimate) | Without dedicated tool | With software | Estimated yearly impact |
|---|---|---|---|
| Paid hours with no proof | 2 to 3 % of hours | under 1 % | 65,000 to 130,000 GBP |
| Payroll preparation time | 6 to 8 days per month | 1.5 to 2 days | 50 to 70 admin days |
| Late cover (site left unstaffed) | 15 to 25 per month | 3 to 6 per month | penalties and credit notes avoided |
| Documented quality audits | 20 % of sites per month | 100 % of sites | contract renewals secured |
| Client disputes over service | 8 to 12 per quarter | 2 to 3 per quarter | 15,000 to 30,000 GBP in credits |
| Gaps between rota and client contract | frequent | automatic alert | billable hours recovered |
A loaded payroll of about 6.5 million GBP for 280 operatives, most part-time and paid at or above the London Living Wage, makes every point of drift expensive. Recovering 1 % alone funds the full software in year one.
2026 cost of custom scheduling software in London
The typical scope covers four blocks: rota and cover, mobile clock-in, quality audits and payroll preparation. Here are 2026 ranges for a company with 200 to 400 operatives.
| Module | Features included | Price (GBP) | Timeline |
|---|---|---|---|
| Rota and sites | client contracts, shifts, assignments, cover, alerts | 16,000 to 32,000 | 5 to 6 weeks |
| Geolocated mobile clock-in | operative app, site geofence, offline mode, backup QR code | 12,000 to 24,000 | 3 to 4 weeks |
| Quality audits | per-site checklists, photos, scores, client PDF reports | 8,000 to 16,000 | 2 to 3 weeks |
| Payroll preparation | hours, premiums, absences, export to Sage or BrightPay | 8,000 to 16,000 | 3 weeks |
| Operations dashboard | hours per site, margin, contract variance | 6,000 to 12,000 | 2 weeks |
| Total | 50,000 to 100,000 | 3 to 5 months |
UK hosting and maintenance run 700 to 1,500 GBP per month. Market SaaS tools usually charge 4 to 8 GBP per operative per month, or 13,400 to 26,900 GBP a year for 280 operatives, rarely with a payroll export matching your premiums or real site-level margin.
Legal points to watch
Employee location tracking falls under UK GDPR and ICO guidance: it should be limited to the moment of clock-in, never continuous, and staff must be informed through a clear privacy notice and a data protection impact assessment. Well-designed software captures location only at clock-in, keeps data for a defined period and offers a QR code alternative. Also plan for accessibility: large buttons, icons and several languages for a multilingual workforce.

With 14,000 GBP of yearly maintenance, the project pays back in about 11 months.
FAQ
Is geolocated clock-in lawful for cleaning operatives?
Yes, if location is captured only at clock-in, a DPIA has been carried out and staff are informed. Continuous tracking is generally considered disproportionate by the ICO.
What happens on sites with no mobile signal?
The app works offline and syncs clock-ins once the signal returns, covering basements and car parks. A QR code posted on site serves as alternative proof of attendance.
Can the software connect to our payroll provider?
Yes, an export to Sage, BrightPay or your bureau's format is part of the payroll module, for 8,000 to 16,000 GBP depending on premiums and allowances.
How long does it take to onboard 280 operatives?
The operative app takes about 10 minutes to learn. Plan 2 to 3 weeks of site-by-site rollout with supervisors as champions.
Can clients get access?
Yes, a client portal with audit reports and hours delivered adds 6,000 to 12,000 GBP and strengthens renewals.
