A customer gets two quotations. One is eighteen pounds an hour and one is seventy five pounds for the clean.
The hourly company suggests four hours, which is seventy two pounds, so it looks marginally cheaper. On the day the house takes five and a half hours and she is charged ninety nine.
The fixed price company would have charged seventy five whatever happened. She compared two rates when the only comparable figure was the total for her specific house.
What a cleaning price is made of
Four components. The time the work takes, the labour rate, the materials and equipment, and the business overhead and margin that the hourly rate has to carry.
Component 1: the time
The dominant factor and the one nobody can state confidently without knowing the property. Size, condition, clutter and scope all move it substantially.
Component 2: the labour cost
What the cleaner is paid, which is the largest part of any rate. A rate substantially below the market is telling a customer something about what is being paid.
Component 3: materials and equipment
Products, machines, replacement and transport. Small per visit, real across a year and frequently absorbed invisibly into an hourly rate.
Component 4: overhead and margin
Insurance, scheduling, admin, recruitment and cover. The part customers do not see and the reason a business rate is not the same as paying somebody directly.
A worked example, priced hourly
A three bedroom house at eighteen pounds an hour. Four hours is seventy two pounds, and five and a half hours is ninety nine. The customer carries the risk of the estimate being wrong.
The same house priced by the job
Seventy five pounds for an agreed scope. The business carries the risk. If it takes four hours the business does well and if it takes six the business absorbs it.
What that comparison actually shows
That the two models allocate risk differently. The rate comparison is meaningless and the total for that specific property is the only useful number.
Why fixed pricing needs an accurate estimate
A business pricing by the job without asking about condition, clutter and scope will either lose money or quote defensively high. The estimate is the whole skill.
Why hourly pricing needs honest time guidance
An hourly business that suggests four hours knowing it takes six is setting up a complaint, and customers experience that as the price changing.
Where hourly genuinely suits the customer
Variable work where priorities change between visits, and smaller jobs where a fixed price would be quoted cautiously.
Where fixed pricing genuinely suits the customer
Defined scopes, regular visits and anything where certainty matters more than flexibility, which is most domestic arrangements.
Publish the basis, not only the rate
A business that explains its model and gives a total for the actual property wins against one quoting a rate, which is the same basis problem as pricing by room versus by area questions.
Quote the total at the enquiry
An assistant that asks about the property size, condition, scope and frequency can produce a total for that house rather than a rate, which is the only figure a customer can actually compare. The exclusions belong in the same conversation, as in what is not included questions clients discover late, the commercial version in office cleaning contracts and the questions buyers ask, and the same openness in how much does an ai receptionist cost. See pricing, run the numbers on the chatbot ROI calculator, and the sector view sits under cleaning services.
