Why businesses keep work in-house when it costs more

Key takeaways

Businesses keep work in-house for five main reasons: control, habit, sunk cost, fear of the handover and a belief that salaried time is free. Some of these are sound for some work. The problem is applying them to everything by default, without ever testing whether they still hold.

• 5 reasons: control, habit, sunk cost, handover fear and free-time thinking.
• Control is a good reason for core work and a weak one for routine work.
• Salaried time is not free: it costs £16.27 an hour at the National Living Wage.
• Test each reason against one specific task, not the whole business.

Why do businesses default to in-house?

Businesses default to in-house because it is the path of least resistance. Giving a task to an existing employee needs no contract, no budget approval and no explanation. The decision is made in seconds, and because it creates no new invoice, it never gets reviewed.

Is keeping control a good reason?

Control is a good reason when the work is core, sensitive or changes daily. It is a weak reason for routine work, where what you need is a reliable result, not the ability to watch it being done. Control over routine work can be kept through a written process, service levels and a weekly check.

Is salaried staff time really free?

No. Using 2026/27 GOV.UK rates, a full-time employee on the National Living Wage costs about £16.27 per worked hour once employer National Insurance, pension and holiday are counted, and a £45,000 manager about £29.98. Every task given to an employee uses hours that have a price, even though the payroll total does not change.

How do sunk costs and handover fear play a part?

Past investment makes change feel like waste. A business that has trained someone, bought software or built a spreadsheet wants a return on it. Separately, owners fear the effort of explaining a task and the risk of it being done badly. Both feelings are real, and both are about the past or the transition, not the ongoing cost.

When are the reasons valid?

The reasons are valid when a task passes three tests: it is central to what customers pay for, it needs knowledge that cannot be written down, and the person doing it is fully used. If a task fails all three, the reasons for keeping it are habit.

• Core: would a customer notice who does this?
• Tacit: could the steps be written on two pages?
• Utilised: does it fill the role, or sit on the side of a desk?

• When is in-house cheaper than outsourcing?

What does the default cost over a year?

The default costs whatever the hours are worth, multiplied by a year. If an in-house task takes a £35,000 employee 6 hours a week, at about £23.20 per worked hour, it costs roughly £6,400 a year before overheads, management or cover. Because that figure never appears on an invoice, it is never compared with an alternative.

The comparison does not have to favour change. Sometimes the in-house cost is lower, and then the default is confirmed with evidence. The point is that a decision worth several thousand pounds a year should be made once, deliberately, and not by habit.

Which reasons hold up best under scrutiny?

Three reasons for keeping work in-house usually survive a proper test.

• Speed of change: the work shifts daily and briefing an outsider would cost more than doing it.
• Deep context: the task depends on knowing individual customers or history.
• Confidentiality: the information is too sensitive to share, even under contract.

How do you review the default without disruption?

Review one function a quarter. Pick the one with the most complaints, delays or senior time in it. Cost it, write down why it is in-house, and test that reason. Most reviews end with a small change, such as moving the routine half of a task and keeping the judgement half. Few end with a wholesale move.

What does this look like in practice?

A pattern we see in owner-managed firms: the owner insists on answering every enquiry personally for quality reasons. Enquiries arriving during site visits wait until evening. The quality reason is real, but it is being applied to the first reply, which is routine, as well as the quote, which is not.
