In House or Outsourced: What a Cleaning Hour Really Costs Your Business

For facilities managers, office managers, school leaders and small business owners, deciding whether to clean in house or appoint a contractor is about more than comparing a wage with an hourly quote. Both figures can hide costs that affect the real price of a reliably cleaned building.

An in house team gives you direct control, but also makes you responsible for employment, cover, equipment and day to day supervision. A contractor takes on much of that operational work, but your organisation still has to set the service, monitor results and manage any change of provider.

The useful comparison is therefore between the cost of delivering the same cleaning service in each model. This guide sets out a practical way to make that comparison, including the employment costs behind a cleaning hour and the transition issues that can influence your decision.

What a cleaning hour costs line by line

The National Living Wage for workers aged 21 and over is £12.71 an hour from April 2026. The National Minimum Wage rates are £10.85 for workers aged 18 to 20, and £8 for workers under 18 and apprentices who qualify for the apprentice rate. Rates change every 1 April.

The headline wage is only the starting point. In a worked example published by Operify AI, a cleaner working 25 hours a week at the April 2026 National Living Wage costs more per hour actually worked because paid leave and employer costs have to be accounted for. The model estimates:

• Wage: £12.71 per productive hour
• Holiday accrual: £1.53
• Employer National Insurance: £1.49
• Employer pension contribution: £0.27
• Absence cover: £0.37
• Training and induction: £0.09
• Uniform and personal protective equipment: £0.10
• Enhanced DBS check: £0.06

The resulting direct labour cost is £16.62 per productive hour, before supervision. Adding £1.65 for supervision, equipment and overhead in the paper’s illustrative contract takes the full cost to £18.27 per hour worked. Adding a five per cent margin produces a charge of £19.23 an hour in that model.

The comparison is a useful reminder that the wage is about 70 per cent of the full cost once supervision and overhead are included. After the wage, holiday accrual and employer National Insurance are the largest lines. Together they add £3.02 an hour in this example.

It is worth separating productive hours from paid hours when making this comparison. A part time operative is paid for their contracted weeks in the year, but works fewer because of annual leave, so the cost of each hour actually spent cleaning is higher than the headline wage. Dividing total employment cost by productive hours rather than paid hours gives a fairer basis for comparing quotes, which are usually built on the time a task actually takes.

These figures are a worked example, not a universal quote or a forecast for every employer. The training, uniform and vetting lines are assumptions and should be replaced with your own payroll and purchasing data. The £1.65 for supervision, equipment and overhead also comes from an illustrative model contract. Actual costs will vary with hours, pay, absence, equipment, pension arrangements and the level of management required.

The DBS figure needs particular care. The paper’s calculation uses a £49.50 check fee. The enhanced check fee fell to £41 on 5 October 2026, so a current costing should reflect the lower fee and the way your organisation allocates it. The difference is small per hour, but it is a useful example of why cost models need to be kept current.

A further planning point is already visible. The published National Living Wage for workers aged 21 and over rises to £13.21 from April 2027. Buyers should model the effect on wages and related employment costs now, rather than assume the current hourly figure will continue.

What in house cleaning involves

An in house team can suit a site that needs regular, predictable cleaning and close control of standards. It can also give managers more direct oversight of timing, priorities and access. Those advantages depend on having the people and systems to run the service well.

The Department for Education’s guidance for schools offers a helpful checklist for any organisation considering this model. It advises buyers to account for staff numbers and hours, planned holidays, absence management, products, equipment, maintenance, storage and utility costs. Training also needs to cover the work staff are expected to do, including safe handling and storage of cleaning agents, equipment use, emergency procedures and waste management.

Employment administration is part of the cost too. Recruitment, payroll, pension duties, right to work checks, inductions, record keeping and arranging cover all take time. If a cleaner is absent, someone must decide whether to cover the shift, move tasks or accept a temporary drop in service. That work can land with a facilities or office manager even when it is not included in the cleaning team’s wage calculation.

There are also responsibilities around safe working. COSHH requirements apply to cleaning products and chemicals, including appropriate information, handling and storage. DBS checks should be completed at the appropriate level for the setting and roles involved. Organisations should check their own insurance arrangements and make sure staff know how to report faults, spills and other hazards.

Product cost is another line to record, but it should not be viewed in isolation. A concentrated product that reduces handling or repeat cleaning may offer better value than a cheaper product that takes longer to use or requires more frequent application. A team may buy professional cleaning products and janitorial supplies through an approved supplier or a cleaning supplies shop, but the comparison should include product use, delivery, storage and the staff time required to complete each task.

The balance between cost and quality is the final consideration in this section. The cheapest product on a shelf is rarely the cheapest in use: a concentrated formula with clear dosing can reduce both waste and the time a task takes. Conversely, premium products only repay their price where the task genuinely demands their performance. Recording what is used, how much and how often turns this from guesswork into a measurable line in the budget.

The time spent managing the service matters just as much as the price of a container. Even a modest weekly workload can require routine checks of stock, equipment and cleaning quality. The Department for Education recommends monitoring daily quality, staff timekeeping, absence, stock levels, faulty equipment and portable appliance testing by qualified personnel. These activities are relevant beyond schools: they help any employer understand whether planned hours are producing the expected service.

What outsourcing transfers, and what it does not

A cleaning contractor is responsible for running its employment operation and delivering the service set out in the contract. Depending on the specification, its price may include recruitment, holiday and absence cover, training, equipment, supervision, reporting and management. The contract should make clear which of these are included and which remain your responsibility.

Outsourcing does not remove the need to describe what good cleaning looks like. The buyer still needs to specify areas, frequencies, standards, access arrangements, periodic tasks and any work that is excluded. It is also your organisation’s job to check performance. Clear inspection routines and a straightforward way to report missed tasks give both sides a basis for resolving problems.

The same applies to consumables and equipment. Confirm who provides cleaning products, machinery, storage and maintenance, and who replaces items that fail. Ask how the contractor manages planned and unplanned absence and what cover is included in the price. The Department for Education advises schools to ask contractors to hold indemnity insurance to protect against loss or damage caused by non compliance. Buyers in other sectors can use the same principle when checking relevant insurance and contract protections.

A low hourly quote is not necessarily a low cost service. Check whether it includes the hours, areas, supervision, cover, materials and periodic work you need. Then compare the contractor's offer with the fully loaded in house figure, not just the cleaner's hourly wage.

How the price is built matters as much as the price

Quotations are built in different ways, and the structure affects how predictable the cost will be. Some providers charge a fixed monthly sum for an agreed service. Others quote an hourly rate and bill for the hours actually delivered. A third approach combines a base charge with separate lines for consumables, periodic work and one off tasks such as carpet or window cleaning.

Each structure has strengths and weaknesses. A fixed monthly price is easy to budget and shifts the risk of overrun to the provider, but it is only reliable if the specification underneath it is complete. An hourly rate can look lower at first glance, yet it exposes the buyer to variation when holidays, absence or additional tasks appear. A combined structure can be transparent, provided each line is defined clearly enough to be checked.

Whatever the structure, ask the provider to show how the price was built. A quote that lists productive hours per area, frequencies and the included materials can be compared line by line with your own loaded cost calculation. A quote expressed only as a single rate per hour or per month cannot be interrogated in that way, and discrepancies usually surface after the contract starts.

Price stability is another question to raise. Employment costs move on published timetables: wage rates and National Insurance thresholds each April, pension contributions with qualifying earnings bands, and vetting fees when the Disclosure and Barring Service revises its charges. A contract that anticipates how such changes will be handled, for example through an annual review linked to published rates, avoids difficult conversations later. A contract that freezes the price for several years while statutory costs keep rising tends to put pressure on either the provider's capacity or the service standard.

The same logic applies inside an in house budget. Payroll lines move when the wage floor moves, and equipment, uniform and training budgets need a review cycle of their own. Building the published April 2027 rates into next year's budget now is simpler than absorbing them as a surprise.

TUPE can affect a change of provider

Before changing an arrangement, establish whether the Transfer of Undertakings (Protection of Employment) Regulations, known as TUPE, may apply. Acas explains that TUPE can apply when a service provider changes, including when office cleaning moves from one contractor to another. It can also apply when a service moves from a contractor to an in house team.

For a service provider change, TUPE may apply where there is an organised grouping of employees whose principal purpose is carrying out work for the client, and the client and work remain mainly the same. There is no minimum group size: it can be one employee. If TUPE applies, employees transfer automatically with their existing terms and conditions. It is not simply a matter of choosing which staff to employ on new terms.

The outgoing employer must provide employee liability information to the incoming employer at least 28 days before the transfer. The employers also have duties to inform affected employees and, where changes are planned, consult them. These requirements make early planning important for both the organisation receiving the service and the provider delivering it.

For schools, the Department for Education advises buyers to consider TUPE and, where relevant, the Local Government Pension Scheme when outsourcing or moving away from local authority provision. It recommends requesting details such as salary, terms and conditions and pension information when giving notice. Other buyers should also seek appropriate advice before building a budget around new staffing assumptions. TUPE details can change the cost materially.

Which model fits your operation?

In house provision can be a sensible fit when cleaning is a frequent and important part of site operations, demand is stable and managers have the time and capability to oversee a team. It may be practical where staff can contribute to other tasks within their role, provided responsibilities, training and service standards remain clear.

Contracting can suit organisations with variable demand, multiple sites or limited capacity for recruitment, cover and supervision. A provider may make it easier to adjust hours or coordinate service across locations, but the value depends on the quality of the specification and contract management.

There is no single model that fits every organisation. The Department for Education identifies three routes for schools: use a framework, run a procurement process or provide cleaning in house. It also notes that renegotiating an existing contract may produce better value than changing provider. That is worth examining before starting a full transition.

Public sector evidence also shows that outsourcing is not the default in every setting. In an APSE survey of councils about public conveniences, 57.1 per cent reported using a wholly in house approach, down from 69.6 per cent in 2025. Only 14 per cent contracted out both cleaning and maintenance. These figures apply to that particular service and group of councils, not all workplaces, but they demonstrate that organisations continue to choose different models as costs and operating needs change.

Workforce availability matters whichever route you take. The British Cleaning Council’s 2026 research, cited in a recent Cleaning Matters article, puts the share of cleaning workers aged over 55 at 29 per cent, compared with 24 per cent across all sectors. Nine per cent of cleaning workers are under 25, compared with 11 per cent across the economy. The article also reports that one in ten cleaning and hygiene operatives received job related training in the previous three months, against one in four across all occupations.

For an in house employer, these figures are a reminder to plan recruitment, retention and training rather than assume suitable staff will be easy to find. A contractor faces the same workforce conditions. Thin margins and rising wage floors can affect the provider's capacity to recruit and maintain reliable cover, which makes sensible contract pricing and performance monitoring important.

Training capacity deserves specific attention in both models. The same Cleaning Matters article notes that the Level 2 Cleaning Hygiene Operative apprenticeship, launched in January 2024 as the sector's first entry route for new staff, stopped receiving government funding for new starts from September 2026. Whether your team is employed directly or delivered by a provider, competence has to be built somewhere. Ask an in house plan how induction and refresher training will be scheduled and funded. Ask a contractor how its staff are trained, what certification they hold and how competence is checked on your site. A provider that can describe its training regime in detail is easier to hold to a standard than one that cannot.

Homeowners buying commercial grade products face a different version of the choice. If you clean your own home, a paid cleaning hour may not be part of the budget, but your time still has value. If you hire a cleaner, agree the tasks and frequency clearly, and check what products and equipment are included. The same principle applies: compare the full service you need, not one price in isolation.

Weighing the risks on each side

Both models carry risks, and they are different in kind. An in house arrangement concentrates dependence on a small number of people: when one leaves or is absent for an extended period, the knowledge of the building, the access arrangements and the standards can leave with them. Recruitment to replace that person takes time, and the work may need to be covered internally in the meantime.

An outsourced arrangement spreads that risk across the provider's workforce, but introduces a different exposure: dependence on the financial health and staffing stability of the contractor. If a provider struggles, service quality can decline before any formal breach is obvious. Checking how a contractor covers absence, how long its site supervisors have been in post and what its staff turnover looks like gives some insight into that resilience before signing.

Plan a change before giving notice

A switch can take longer than expected. Before deciding, gather the current agreement’s expiry date, notice period and likely contract value. The Department for Education recommends working backwards from the intended start date and, where possible, aligning a new service with the start of a financial or academic year or the period after a major holiday.

First consider whether the current provider can address the problem through a revised specification or renegotiation. If a change is still needed, map the steps for procurement, staff communication, TUPE information, equipment, product supply, site access and service checks. Be clear about who will respond to missed tasks, manage stock and report equipment faults from the first day of the new arrangement.

The cost model should also reflect the service you are buying. Compare the expected productive hours and tasks, not just the headline hourly rate. Allow for periodic cleaning, emergencies, holiday cover and any products or machinery excluded from the quote. If provision is moving in house, include management time and the cost of maintaining equipment and replenishing supplies.

Communication with affected staff should start early in either direction. Employees who hear about a possible change through rumour tend to assume the worst, and a provider losing a contract may begin planning its own staffing changes as soon as notice is given. Clear, factual updates about what is known, what is not yet known and when decisions will be made reduce uncertainty for everyone involved. Where TUPE applies, the formal information and consultation duties will structure much of this communication, but good practice goes beyond the legal minimum.

Keep a dated record of the decision process as you go: the figures you compared, the assumptions behind them, the options you considered and the reasons for the final choice. If the arrangement later needs revisiting, that record becomes the baseline for the next review. It also helps when a new manager inherits the contract and needs to understand why it takes the shape it does.

A practical comparison checklist

Before choosing a model, make sure you can answer these questions:

1. What areas and tasks need cleaning, and how often?
2. How many productive hours does the required service involve?
3. What is the full in house employment cost, including paid leave, employer National Insurance, pension, absence cover and management?
4. Which training, uniform and vetting costs are based on assumptions, and what are the actual figures?
5. Who provides products, equipment, storage, maintenance and cover?
6. What are the current contract expiry date, notice period and likely value?
7. Could TUPE or pension arrangements affect the transfer?
8. How will quality, timekeeping, stock and equipment faults be checked?
9. Has the April 2027 National Living Wage rate been included in forward planning?
10. Could an adjustment to the current service or contract deliver the required improvement?

A cleaning hour has no single universal cost. The right figure depends on the people, cover, equipment, management and standards needed at your site. A careful comparison makes those costs visible, supports a smoother decision and helps you choose an arrangement you can manage reliably.

Whichever route you choose, review it on a fixed cycle rather than leaving it until a contract ends or a problem forces a decision. An annual review of hours, standards, costs and satisfaction catches drift early, while the comparison is still fresh and the options are still open. Cleaning arrangements tend to work best when they are managed as a living service, not filed away as a settled decision.
