How to Grow a Plastering Business in the UK
The short answer
Price every job for a team, not for your own day. Then build work that keeps a gang busy all year, hire in the right order, train a second finisher so the walls don't wait for you, and job-cost every job.
- Price for a team first. An employee on £18 an hour costs about £27.40 per chargeable hour before overheads and profit.
- Build steady work. Mix domestic re-plasters with measured work for builders and drylining packages, so the diary never empties.
- Stop being the only finisher. If only you can put a finish on a wall, every job waits for you.
- Job-cost every job. A job priced for 64 hours that takes 80 drops from a 30% margin to 17.5%.
Most plasterers hit the same wall. The phone rings, the diary is booked for weeks, and builders keep asking if you can start Monday. But the business is still you, a labourer and a van. You can't take more work because there is no more of you.
This guide shows how to grow a plastering business in the UK past that point. It covers team pricing, steady work, your first hires, the finishing bottleneck and simple systems.

The four stages of a plastering business
Every plastering business we see sits at one of four stages. Each one needs something different from the owner.
- One-man band: you price, plaster, clean up, invoice and chase. Growth stops at your hours.
- You and a labourer: you still finish every wall, but someone mixes, preps and carries.
- Two or three gangs: you run the prices, the builders and the diary. You pick up a trowel only when you choose to.
- A company: a lead plasterer runs the sites and someone runs the office. You run the business.
The five steps below move you from one stage to the next. Skip one and the business usually slides back.
Step 1: price every job for a team
Most one-man bands price for their own day, or by the m² rate everyone else uses. That price falls apart the moment you pay someone else to do the work.
Our plastering playbook works it out like this. An employee on £18 an hour costs about £27.40 per chargeable hour. That covers employer National Insurance, pension, holiday and the hours lost to travel and the yard. Then add a margin floor: 20% for overheads and 10% for profit makes 30%.
So the lowest price for that hour is £27.40 ÷ 0.70 = £39.14. Below that, every hour your plasterer works makes the business poorer. For a full worked quote from survey to price, see how to price plastering jobs.
Price from hours, then turn it into a m² rate to check it against the market. Never the other way round. The plastering business profit margin guide shows the true m² rate for skims, re-plasters and drylining.

Step 2: build work that keeps a gang busy
A team needs a steady week, not a full one followed by an empty one. One-off jobs from lead sites rarely give you that. Most growing plastering businesses mix three kinds of work:
- Domestic re-plasters and skims: you price the job, the homeowner pays in stages and the margin is yours to set. But the jobs are small and each one needs a survey and a quote.
- Measured work for builders: steady, repeat work from a few builders who know you. They compare by the m², pay later, and may deduct CIS and hold back retention.
- Drylining and commercial packages: bigger values and longer runs of work for one gang. They need paperwork, insurance and cash to wait 30 days or more.
Domestic work pays faster. Builder and commercial work fills the diary. The skill is keeping enough of each so a late payer can't stop the business. Read how to get commercial plastering and drylining contracts before you price your first package.
Render and outside work slows in winter. Plan inside work for those months before you hire for the summer.
Step 3: hire in the right order
A labourer makes you faster, but you are still the only one who can finish. Your first real hire is a plasterer who can run a room without you.
A sensible order for most plastering businesses:
- A plasterer who can finish. This frees you to price, sell and check work.
- A labourer or improver for each finisher. Mixing, prep, protection and clean-up, so the finisher's hours go on the wall.
- An apprentice. A CITB registered employer gets £2,500 a year in attendance grant and £3,500 on completion. On a two-year apprenticeship that is up to £8,500. Dry lining apprentices on the Interior Systems Installer route get up to £2,000 more.
- Part-time admin. Quotes, invoices, CIS statements and chasing, so they stop eating your evenings.
- A lead plasterer. When two or three jobs run at once and someone has to check the work.
Labour-only plasterers are a fair way to test demand before you take on staff. But if you direct them and supply the materials, they usually count as your employees for insurance. Check employers' liability insurance for subcontractors before you rely on them.
Before each hire, check your prices carry the new wage at your true hourly cost. Can't find anyone? See what to do when you can't find workers. For the legal steps, see hiring your first employee.

Step 4: stop being the only one who can finish
Here is the bottleneck most growth advice misses. In plastering, the finish is the product. Builders and homeowners judge you by the wall in the light from the window, not by how fast you boarded.
If only you can put a finish on a wall that you are happy with, every job waits for you. Your team can hack off, bead, board and float all week. But the rooms stay unfinished until you turn up.
The fix is to train a second finisher to your standard, and write that standard down:
- What "finished" means Flat under a light held to the wall, clean angles, beads straight, no trowel marks.
- How you check it A walk-round with a torch before the client sees it.
- How you hand over Drying times, when to mist coat and what is not included, in writing.
When the standard is on paper, you can check a room in ten minutes instead of finishing it yourself.

A team copies what you do. If nothing is written down, every job runs a different way and you end up checking all of them.
Start with four simple systems:
- A job pack: survey notes, room list, materials, photos and the client's contact details, ready before day one.
- Protection and prep: what gets covered, taped and sheeted on every job, so no gang leaves dust on a client's carpet.
- Measuring and variations: extra work is written down and priced before anyone does it.
- Job costing: hours and materials against the quote on every job.
Job costing is how you know what to grow. In the example in our playbook, a job priced at a 30% margin for 64 hours took 80. The margin fell to 17.5%. Without the numbers, that owner would keep pricing the same way and wonder where the money went.
Our construction business systems guide shows how to set these up without a big software bill.
What growth looks like for plasterers
Liam, a plasterer in our mentorship, signed a £79K house renovation six weeks in and built a £1M pipeline.
Clayton, another plasterer, now signs work with £5K upfront and staged payments. His first project after our call was £10K.
Oleg started as a taper and jointer on £100 a day. He moved from the tools to running jobs and built a team of 10+. Individual results, not typical or guaranteed. See more client results.
Oleg, taper & jointer: £100 a day to £7K a month profit
A 19-year-old from London who set up his own company and built a team of 10+ in two months. Individual results, not typical or guaranteed.
That is how Sviat Jay works with owners. He runs Craftex, a London construction company, and mentors owners one to one himself. Every business has different strengths: one owner sells well, another runs jobs well. He finds yours and builds on them. He aims for results in about 4 months, not the 1–3 years many coaching programs take.
Small groups are there for owners who want to start with a lower commitment. If you want to stop being the business and start running it, book a free strategy call, or see how our mentoring programs work.
Mistakes that keep plasterers small
- Hiring before pricing: a new wage on old prices makes you busier and poorer.
- Pricing by the going m² rate: it ignores hacking off, beads, high ceilings and a full house of furniture.
- One builder for all your work: if they pay late or go quiet, the whole team stops.
- Being the only finisher: your trowel becomes the limit of the business.
- No job costing: without it you can't tell which work to grow and which to drop.
Before your next hire
- Your prices cover about £27.40 per employed hour plus a 30% floor
- No single builder brings in most of your work
- A second plasterer can finish a room to your written standard
- You know which CITB grants you can claim for an apprentice
- Every job is costed against its quote
