Building a cleaning rota, and covering the 6am sick call

A rota is not a list of names against times, it is a constraint problem with about eight conditions that all have to hold at once. Cover is the same problem again, solved in ten minutes, before the building opens, with worse information than you had the first time.

What a rota has to satisfy at the same time #

  • The access window

    The site can only be cleaned between certain hours, and somebody has to be able to get in: keys, a fob, an alarm code, a signing in book at reception.

  • The specification

    Daily, three times a week, weekly, plus periodic work that has to land somewhere.

  • Contracted hours

    Part time people with agreed hours who will notice immediately if they get fewer.

  • Geography

    Two or three sites in one shift only works if they are close enough, and the travel between them is paid time.

  • Rest rules

    A 20 minute break when a working day runs past 6 hours, 11 hours between working days, and 24 uninterrupted hours off each week or 48 each fortnight.

  • Site specific clearance and training

    Schools, care settings and secure sites do not accept whoever is free.

  • Who the client will actually accept

    Contract managers have preferences and they are real, whether or not they are written down.

  • Lone working

    HSE lists cleaners among lone workers and says employers must manage the risks before people work alone. Who is alone, where, and at what hour is a rota decision.

Eight conditions across every site and every person is why the rota is built by the one person who holds all of it in their head, and why that person cannot take a holiday.

Why the 6am call costs more than the shift #

A sick call is not a gap, it is a cascade. The obvious cost is the replacement hour. The real costs are underneath it.

  • Travel time

    You pay travel time for somebody coming from further away, and that travel counts towards minimum wage hours because it is movement between assignments rather than a commute.

  • Overtime, or a broken rest pattern

    You may push a person into overtime or into a pattern that breaks the 11 hour rest rule.

  • A hole somewhere else

    You may take somebody off another site, which moves the problem rather than solving it.

  • The site, or a stranger on it

    If nothing can be found, you either leave the site or send somebody who has never been there, which is the most common starting point for the call about a missed clean.

Because the National Living Wage is £12.71 an hour for workers aged 21 and over from 1 April 2026 and most contract cost is hours, the margin on a site does not have much room in it for repeated cover premiums.

The information problem underneath #

Solving cover in ten minutes requires knowing, immediately:

  • Who is trained and cleared for that site
  • Who is not working right now
  • Who is within reach
  • Who is under their hours
  • Who has the access method
  • Who the client will accept

On most rounds that information lives in four places, which are a spreadsheet, a WhatsApp group, a folder of induction records and the supervisor's memory.

When the contract changes hands #

TUPE is likely to apply when a cleaning contract moves to a new contractor or comes back in house. GOV.UK gives the cleaning example directly.

For the rota that means inheriting people with existing terms, existing hours and existing continuity, at a site you have just priced. Whatever your rota holds has to be able to absorb a group of people who did not come through your onboarding, which is the practical reason onboarding records matter more than they look.

Which parts run on rules #

Runs on rules

  • Reissuing a stable rota week to week
  • Publishing shifts to the people working them
  • Checking a proposed pattern against rest and hours rules
  • Knowing who is trained and cleared for a given site, if it is recorded anywhere reliable
  • Producing the shortlist of who could cover a shift. This is a lookup, not a decision
  • Flagging an unfilled shift before the site opens

Needs a person

  • Choosing between two people who could both cover
  • Deciding whether to tell the client before they notice, where the answer is usually yes
  • Designing the rota in the first place. It is about people, travel and what a site will tolerate

Counting it #

Count two numbers for a month: how many cover events you had, and how long each one took from the call to the problem being solved. Most operators are surprised by the second. The free tools turn that into hours, and the free audit looks at the whole office week rather than one job.

Questions people ask

Why is covering one sick shift so expensive?
Because it is the same constraint problem as building the rota, solved in ten minutes with worse information. You are looking for somebody who is trained and cleared for that site, has access to it, is not already over their hours, will not breach a rest break or daily rest rule, and can physically get there before the building opens. Solve it badly and you pay travel and overtime for a shift you already priced at contract rate.
Does travel between sites have to be paid?
GOV.UK guidance on the minimum wage states that travelling from one work assignment to another counts towards the hours for which the minimum wage must be paid. Ordinary commuting from home to a workplace does not. On a round where people do two or three sites in a shift, that distinction decides whether a contract is profitable.
What rest rules constrain a cleaning rota?
Workers have the right to one uninterrupted 20 minute rest break during the working day if they work more than 6 hours, 11 hours rest between working days, and either 24 uninterrupted hours without work each week or 48 hours each fortnight. Early and late splits on the same day are where rotas most often run into the 11 hour rule.
What happens to the rota when a contract changes hands?
TUPE is likely to apply. GOV.UK gives the example of a cleaner employed by a company that decides to use an outside cleaning company instead, and says they are likely to be protected. That means people, their terms and their continuity arrive with the contract, and your rota has to absorb them rather than replace them.
