1. What you'll actually be doing
Screeding isn't glamorous and it isn't easy. You're the person who turns a rough slab or insulation layer into a flat, level surface that every trade after you depends on. If your screed is wrong, the flooring fails, the tiles crack, and the UFH doesn't perform. No pressure.
A typical day looks like this: turn up early, unload gear, check the drawings and datum lines, talk to the builder or site manager about areas and access. Then it's prepping, membranes, insulation, edge strip, checking UFH pipes are secure, setting level pins or tripods, and working out falls to drains if needed. Then you mix and lay, rule off to level, finish it (floating, trowelling, or dapple bar depending on the type), and protect the area so nobody tramps through it before it's ready.
There are three main types of screed you'll work with:
Traditional sand and cement (hand or pumped) Mixed on site in a forced-action or pan mixer at roughly 1:3 to 1:4.5 cement to sharp sand. Barrowed or pumped in, levelled off rails, compacted and floated by hand. Good for smaller or fiddly areas, falls to wet rooms, sloped areas, or thicker build-ups.
Liquid / anhydrite / flowing screed Ready-mix truck and a pump. Free-flowing calcium sulphate material. You set the perimeter detail and levels, they pump, you dapple it for air bubbles and flatness. Very fast on big open areas and brilliant with underfloor heating because of high thermal conductivity.
Fast-set / rapid-drying Bagged products (cementitious or proprietary) that dry much quicker than traditional screed. Used where flooring needs to go down in days, not weeks. Strict water ratios, mixing instructions, and thickness limits. More cleaning and batch control, less forgiving of shortcuts.
Pump vs hand-lay: Pump work means bigger footage, less barrowing, but more pipework, cleaning plant, and site logistics. Hand-lay is hard graft with barrows and shovels, more time on your knees, but lower kit overhead and better suited to small builders and domestic jobs.
2. Kit and startup costs
If you're starting small and hand-laying, here's what you actually need:
Bare minimum to get earning:
| Item | Budget |
|---|---|
| Forced-action mixer or pan mixer (hire to start) | ~£60–£120/day hire, or £2–5k used to buy |
| Straightedges / "Darby" bars, floats, trowels, rakes, spades, buckets, wheelbarrows | £300–£800 for a decent set |
| Rotary laser level with receiver and staff | £300–£800 (entry-level; a better one pays you back in speed and accuracy) |
| Moisture meter and surface testing kit (hygrometer or moisture box kit, CM test kit) | £100–£300 |
| PPE (waterproof boots, knee pads, cement-rated gloves, dust mask, goggles, ear protection) | £100–£200 |
Total to get started (hand-lay, hired mixer): Under £1.5–2k in tools and PPE, plus van and insurance.
Pump hire vs ownership:
- Small screed pump or liquid screed pump hire: roughly £250–£400/day including hoses, plus cleaning charge and delivery.
- Buying a pump: £15k–£40k+ for a decent trailer pump or liquid screed rig. Only makes sense once you've got regular large pours booked in. Don't rush this.
PPE notes specific to screeding:
- Waterproof boots with good soles · you're standing in wet cement or anhydrite regularly.
- Knee pads or kneeling boards · you'll live in them.
- Cement-rated gloves · cement is caustic and will burn your skin.
- Dust mask and goggles for mixing powders.
- Ear protection around mixers and pumps.
3. Qualifications and cards
To get on most proper sites:
- CSCS card: Green Labourer card to start (pass the CITB HS&E test). Then aim for a Blue Skilled Worker card once you've got your NVQ.
- NVQ Level 2: Floor screeding usually sits under "Specialist Concrete Occupations · In Situ Flooring." This backs up your Blue CSCS card and proves you know what you're doing.
Worth getting:
- Flowing Screeds Association (FSA): They support flowing screed installers and offer training and technical information. Worth it if you're doing liquid/anhydrite regularly.
- Manufacturer courses: Companies like Cemfloor, Flowcrete, and Cemex often run 1-day installer courses for their systems. These are a genuine selling point to specifiers and builders · it shows you've been trained on the specific product, not just winging it.
The honest truth: Nobody is checking for fancy certificates on a domestic extension. But on commercial or larger residential jobs, NVQ + CSCS + a couple of manufacturer tickets makes you look like you belong, and gives you access to sites where the real money is.
4. Pricing your work
These are UK 2025–26 ranges. You'll adjust for your area and overheads.
| Screed type | Typical range per m² |
|---|---|
| Traditional sand and cement | £20–£33 |
| Liquid / anhydrite / flowing | £25–£34 (usually supplied and pumped as a package) |
| Fast-drying screed | £26–£34 (higher material cost, more care) |
| Self-levelling / smoothing compounds | £27–£36 (finishing layer) |
Minimum charges: For small domestic areas (bathrooms, porches, small kitchens), most screeders set a minimum job value, say £300–£600+VAT. Loading out, travel, and cleanup cost the same whether it's 6 m² or 40 m².
What pushes the price up:
- Thickness: More depth = more material and labour. Quote per m² with a material uplift for extra depth.
- Underfloor heating (UFH): More prep time around pipes, edge strips, checking manifolds, and more risk if there's an issue later. Most screeders add a premium for UFH pours.
- Access: Narrow doorways, upstairs, no pump access · all add time and sweat.
- Falls: Wet rooms and drain falls need more skill and more time.
Pricing tip: Don't just copy someone else's rates. Work out what it actually costs you per day (materials, fuel, insurance, kit hire, your time), then price jobs so you're making money after all of that, not just looking busy.

5. Common mistakes and disputes
This is where people lose money, lose clients, and lose sleep. Learn from everyone else's mistakes.
Cracking and curling Usually down to wrong mix ratio, poor curing, too thin, or no movement joints. Traditional screed shrinks as it dries, you need the correct thickness and reinforcement where needed. If you cut corners on this, the floor fails and it's on you.
Drying times ignored Ballpark: traditional screed dries at about 1 mm per day in good conditions. Thicker sections and cold or damp sites slow that down significantly. Rushing this is the single biggest cause of disputes in screeding.
Flooring laid too early If the floor fitter goes on before the screed is dry enough and traps moisture, you get debonding, blown vinyls, or tiles popping. This is where clear paperwork saves you.
Moisture testing: do it every time Offer or require moisture tests before final floor finishes go down. Hygrometer box tests, CM tests, or similar. Put it in your quotes and method statements that the screed must reach the manufacturer's moisture limits before floor coverings go down, and state clearly who is responsible for testing.
Who's liable when things go wrong?
- If you've mixed and laid it wrong (wrong mix, wrong thickness, no prep) · that's on you.
- If you've followed the spec, warned about drying times, and a flooring contractor or builder ignores it · you can argue it's their risk. But only if you've got it in writing.
- For liquid or proprietary screeds, follow the manufacturer's data sheets to the letter. That's what your insurance and their warranty will look at.
Protect yourself: every single job:
- Photos of prep, membranes, insulation, UFH, and expansion joints.
- Clear written notes on drying times, traffic limits, and when the screed is ready for the next trade.
- Keep your method statements and RAMS up to date.

6. Where the work comes from
Realistically, your pipeline will be:
Builders and main contractors · extensions, new builds, refurbs. Usually repeat work once they trust you. This is your bread and butter.
UFH installers · they like having a reliable screeder they can recommend, because their system is only as good as your screed. Get in with one or two good UFH firms and they'll feed you work.
Flooring contractors · for latex, self-levelling, and remedial screeds before vinyl, LVT, carpet tiles, etc.
Direct homeowners · mostly off Google, Facebook, local recommendations, and MyBuilder-type sites. Typical jobs are one-off kitchens, conservatories, and refurb projects.
The smart play: Build relationships with a couple of good builders and one or two UFH or flooring firms. That keeps you busy with reliable repeat work. Fill gaps with domestic jobs. Don't rely on one source of work, if your only builder client goes quiet, you need other options.

7. Industry bodies
There isn't a single "Screeders Guild," but these are worth knowing about:
Flowing Screeds Association (FSA) · aimed at flowing screed manufacturers and installers. Offers training, technical datasheets, and raises standards in the UK and Ireland. Being a member or using their guidance helps when you're writing method statements, RAMS, and trying to look credible to larger contractors.
Concrete and flooring associations · various bodies cover screeds in their guidance and CPD. Not screeding-specific, but useful for technical reference.
CITB · for your CSCS card, NVQ funding, and grants if you're taking on an apprentice.
8. What you can expect to earn
These are ballpark UK figures. Rates vary by region and whether you're PAYE or self-employed.
Starting out (site labourer / improver):
- On wages for a firm: roughly £110–£150/day depending on area and whether you've got a CSCS card.
- As you pick up skills (setting levels, running a mixer, finishing, working safely): pushing into £150–£170/day.
Experienced screeder (good finisher, can run jobs):
- Self-employed or in a small gang: day rates of roughly £180–£250, sometimes more on big, awkward, or unsociable-hours jobs.
- Running your own company and managing a small gang: clearing £40k–£60k+ per year is doable once you're established and busy. But you'll work for it.
The main levers on your earnings:
- How efficient you are (metres per day).
- Your mix of small domestic vs big commercial.
- How much kit you own vs hire.
- Whether you're doing the selling and quoting, or just the laying.
9. The improver reality
Most people coming out of training or starting in screeding aren't fully job-ready on day one. That's normal. You'll likely spend your first months as an improver, learning the feel of different mixes, getting your speed up, understanding how different sites and conditions change the job.
Don't pretend you know more than you do. Ask questions. Watch how experienced screeders read a floor, check levels, and deal with problems. The ones who learn fastest are the ones who aren't afraid to say "I haven't done that before, show me."
10. Know your worth
When you're starting out, the temptation is to say yes to everything. Every quote, every job, every favour. The problem is you end up running between jobs, rushing, doing lower quality work, and not actually making more money. You're just busier and more tired.
Learn to say no. Five cheap domestic pours where you're losing money on travel and loading out pay less than two proper jobs priced right. A job that doesn't cover your costs isn't a job, it's a favour. Quality screeding gets callbacks and referrals. Rushing doesn't. Price properly, do good work, and the right clients will find you.
11. Don't be afraid to ask
You will hit things you haven't seen before, a weird substrate, a spec you don't understand, a product you've never used. Don't guess.
- Ring the manufacturer's tech line. That's what it's for.
- Ask your previous employer or mentor. Most will help if you're respectful about it.
- Check the FSA guidance or product data sheets.
- If it's a structural or design question, push it back to the architect or engineer. That's their job, not yours.
Guessing on screeding leads to cracked floors, failed pours, and callbacks that cost you more than the job was worth.
