The real cost of doing nothing
A commercial manager on £70,000 who spends fifteen hours a week on automatable admin costs you roughly £26,000 a year in lost capacity. Across a team of five that is about £130,000, and it never appears on a line item, which is exactly why it goes unchallenged for years.
Walk through any mid-sized contractor's commercial department on a Monday. You will find people doing what they did last Monday: pulling data from one platform into Excel, cross-referencing it against emails, formatting it into a report, and sending it to someone who will want a slightly different version by Wednesday. That is not work. It is overhead disguised as productivity.
Where does the £26,000 figure come from?
From a model you can check and disagree with, rather than a statistic. Substitute your own numbers and it still works. If you want an external anchor for the inputs rather than ours, the ONS construction industry statistics and the government construction statistics collection are the primary UK sources for output and employment data.
| Input | Value | Assumption |
|---|---|---|
| Salary | £70,000 | Mid-level commercial manager |
| Productive hours per year | 1,800 | 46 working weeks, allowing for leave and non-productive time |
| Effective hourly cost | ~£39 | Salary divided by productive hours. Excludes on-costs, so this is conservative |
| Hours per week on automatable admin | 15 | Re-keying, reformatting, report assembly |
| Hours per year | ~690 | 15 hours across 46 weeks |
| Annual cost, one person | ~£26,800 | 690 hours at £39 |
| Team of five | ~£134,000 | Same assumptions, five people |
Two things about that table. The hourly rate excludes employer's national insurance, pension and overheads, so the real number is higher than shown. And if fifteen hours a week sounds high for your business, halve it: £13,000 a year for one person is still not a rounding error.
Why does nobody act on a six-figure cost?
Because it is invisible in three specific ways, and each one defeats a different part of how businesses notice things.
It is spread thin. No single task looks expensive. Ten minutes re-keying subcontractor figures. Half an hour renaming files. An afternoon assembling the monthly report. Each feels like part of the job, so nobody adds them up.
It is disguised as diligence. The person compiling the report pack looks busy and conscientious, and they are. The problem is not the person. It is that the work they are doing should not exist.
There is no invoice. Businesses scrutinise costs they can see. A software subscription gets challenged at every renewal. £130,000 of skilled time spent on copy and paste never reaches anyone with the authority to stop it.
What test can you run this week?
Walk the office floor and count how many times someone copies information from one system into another. From an email into a spreadsheet. From a CDE into a report. From a programme into a narrative.
That count is your automation opportunity, and it is larger than you expect. Most of it can be removed using tools you already own: Outlook, SharePoint, Excel, Teams, WhatsApp. It does not need a new platform, a migration project or a training programme. It needs someone who knows where construction businesses actually lose their hours, which is the difference between automation and buying more software.
What does the recovered time actually buy?
Judgement, put back where it earns money. The point is not to cut heads.
A QS who is not re-keying figures is checking entitlement and protecting margin. A commercial manager not building the monthly pack is negotiating. A site manager not writing up the diary at seven in the evening is planning tomorrow properly. Directors get an honest picture without chasing five people for updates.
Every hour of admin removed is an hour of professional capability recovered at zero recruitment cost. Set that against what it costs to hire your way to the same capacity and automation stops being a technology decision and becomes a margin decision.
The firms that make it early operate faster and leaner than the ones still paying skilled people to do a robot's job. The gap compounds monthly, and it is already visible in who wins the work.
