What Actually Comes Out of a Day Rate
| Cost category | Typical impact | Notes |
|---|---|---|
| Materials | £20-£60/day | Bonding, finish, beads, PVA — varies hugely by job type |
| Travel and fuel | £10-£30/day | Higher on spread-out domestic jobs than a single site |
| Tools and consumables | £5-£15/day (averaged) | Mixing paddles, hawks, trowels wear out and need replacing |
| Insurance and scheme fees | £3-£10/day (averaged) | Public liability, and any trade body membership, spread across working days |
| Quoting and admin time | Unpaid | Every hour spent quoting a job you don't win is an hour not billed |
| Gaps between jobs | Unpaid | Weather, cancellations and scheduling gaps that a "day rate" doesn't account for |
Worked Example: A £180 Day Rate Job
Take a standard skim job charged at £180 for the day:
- Materials: -£35
- Travel/fuel: -£15
- Tools/consumables (averaged): -£8
- Insurance/scheme fees (averaged): -£6
That leaves roughly £116 before tax — already 36% below the headline £180. And that's before factoring in the time spent quoting the job in the first place, or the days you're not on the tools at all.
The number that actually matters: not your day rate, but your cost per billable hour — what's left once materials, travel and overheads are stripped out, divided by hours actually worked. For the full method, see our real hourly rate calculator guide.
The Part Most Plasterers Miss: Gaps Between Jobs
A day rate assumes every working day is billable. In practice, weather delays, customer cancellations, and the time it takes to line up the next job all eat into that. If you're realistically billable 4 days out of every 5, your effective day rate has already dropped by 20% before a single material cost is deducted.
How to Raise Real Profit — Not Just Your Day Rate
- Cut quoting time — a faster quoting process means more quotes sent per unpaid hour, not just a higher headline price
- Cluster jobs geographically — reducing daily travel has a direct, compounding effect on what you keep
- Buy materials smarter — trade accounts and bulk buying on bonding/finish narrow the materials line without cutting quality
- Reduce gaps — better scheduling and faster follow-up on quotes keeps more days actually billable
Cutting quoting time is one of the easiest wins on that list — TradeQuoteAI turns a job description into a sendable quote in under a minute, so less of your day disappears into admin you don't get paid for.
Raising your day rate is the obvious lever, but it's not the only one — and it's often not the biggest one. For current UK plasterer day rates by region to benchmark against, see our plasterer day rate guide, and for a full room-by-room pricing breakdown, our guide to pricing plastering work.
Frequently Asked Questions
Is a plasterer's day rate the same as their profit?
No. Materials, travel, tools, insurance and unpaid admin/quoting time typically reduce a £180 day rate to closer to £110-£130 in real terms.
What has the biggest hidden impact on plastering profit?
Unbillable time — quoting jobs you don't win, and gaps between jobs caused by weather or scheduling — often costs more than materials do.
How can plasterers increase profit without raising prices?
Cutting quoting time, clustering jobs to reduce travel, and buying materials through a trade account all improve margin without touching the headline rate.
