Microcement floor cost: UK 2026 prices per m², by project size
Floors are the biggest microcement projects by area, so the per-square-metre rate gets scrutinised harder here than anywhere else. This is the floor-specific detail behind our full microcement cost guide: what the 2026 rate actually buys, how project size moves it, what different substrates add, and how the numbers stack against polished concrete, resin and porcelain.
The per-m² rate, and what it includes
In 2026, a hand-applied microcement floor installed by a specialist across London and the south-east costs £120–£200 per square metre, all materials and labour, VAT usually on top. That buys the full system: floor-grade primer matched to the substrate, fibreglass mesh, two base coats, two finish coats, and a floor-rated polyurethane sealer — the build-up described on our microcement flooring page. Outside the south-east, rates often run 10–20% lower with regional labour costs.
Floors sit above the wall rate (£100–£180/m²) for three reasons: the material build is heavier, the sealer specification is more demanding because floors take abrasion, and most floors need some screed preparation before priming. A quote materially below £100/m² for a floor is usually missing one of those three — the red-flags checklist in the cost guide explains what each omission costs you later.
Cost by project size
Setup costs — mobilisation, materials minimums, protection, the first day's prep — are roughly fixed whether the floor is 15 m² or 60 m². That's why per-m² pricing falls as area rises:
- Single room over existing screed, 15–20 m² — £2,500–£4,500. The cheapest way into a microcement floor, but the least efficient per square metre.
- Open-plan ground floor, 40–60 m² — £7,000–£12,000. Economy of scale arrives here; per-m² rates typically come down 10–15% versus single-room work.
- Whole house, 120–150 m² over multiple floors — £18,000–£32,000. Larger projects spread the same setup across more area, and the crew's day-rate output improves as the job settles into rhythm.
One planning note: continuous floors read best when they genuinely continue. If you're pricing an open-plan space, quote the hallway and WC floor at the same time — adding them later means a second mobilisation charge and a colour-batch match that's never quite as clean.
Substrate: where floor quotes actually diverge
Two floor quotes 40% apart are almost never charging different rates for microcement — they're assuming different substrate work. The common scenarios:
- Cured, sound screed — the baseline. Prime and go; no addition.
- Cracked but structurally sound screed — grinding, crack-filling and a mesh upgrade add £15–£30/m² before priming starts.
- Existing tiled floor — microcement overlays it at the standard rate, and you save the £20–£40/m² a rip-out plus screed repair would cost. The full overlay system — grout treatment, non-absorbent primer, tap-testing — is in microcement over tiles.
- Timber floorboards — boards flex, so they're overboarded with ply to create a stable plane first. Budget the overboarding as a separate carpentry item (typically £25–£45/m² supplied and fitted) plus the standard microcement rate.
- Fresh screed in a new extension — no prep cost, but cure time is a programme cost: a new screed needs to finish its moisture release before priming, and rushing it is one of the classic causes of the failures catalogued in common issues.
Versus the alternatives
Installed 2026 prices for the finishes microcement floors are usually compared against, mid-range residential spec in the south-east:
- Polished concrete — £100–£150/m² on large areas, but it needs a 75–100 mm structural slab: realistic in a new extension, rarely in a renovation. Microcement delivers the same visual language at 2–3 mm over what's already there — no dig-out, no door and threshold rework, no weeks of curing.
- Epoxy or PU resin — £90–£150/m² residential. Comparable seamlessness, colder and more plastic in appearance, and self-levelling resin needs similarly obsessive substrate prep. Where resin wins is chemical resistance (garages, plant rooms); where microcement wins is warmth of finish and the ability to run the same material up walls and joinery.
- Large-format porcelain — £80–£150/m² installed once adhesive, levelling and labour are counted. Cheaper at the bottom end, but it reintroduces grout, thresholds and the maintenance cycle that goes with them — the lifetime numbers below tell that story.
- Engineered timber — £70–£130/m² fitted. A different aesthetic entirely; the comparison that matters is practical — timber moves with humidity, marks under furniture, and doesn't belong in wet zones, where a continuous microcement floor runs straight through.
Underfloor heating: same rate, longer programme
Microcement over UFH is priced at the same per-m² rate as a standard floor — the material cost difference is a heavier 100 g/m² mesh, which is marginal. What changes is the programme: the heating has to be fully commissioned and cycled before we start, and the schedule adds one to two weeks around that. The commissioning sequence, and the spec decisions that stop a heated floor cracking, are covered in underfloor heating compatibility.
Lifetime cost of a microcement floor
A residential microcement floor's maintenance schedule is short: mop with neutral cleaner, and plan a sealer refresh around year 10–12 in heavy-traffic areas — roughly £1,200 for a typical ground floor, done in place in a day, no demolition. The base layers stay down indefinitely; only the top coat renews.
Compare the alternatives over the same 15 years: porcelain wants grout deep-cleaning and eventual re-grouting in traffic lanes; timber wants re-oiling every 2–3 years or a full sand-and-refinish around year 10 (£30–£50/m²); resin typically wants a re-coat by year 10 in domestic traffic. None of these are ruinous — but they narrow or erase microcement's apparent premium at the sticker stage. The full 15-year comparison methodology is in the cost guide.
Comparing floor quotes like-for-like
Line items to check before comparing totals — a floor quote that's silent on these isn't cheaper, it's incomplete:
- Substrate prep — is grinding/crack repair included, priced provisionally, or excluded? This is the biggest hidden variable.
- Mesh — specified across the whole floor, with the upgraded weight over UFH?
- Sealer grade — floor-rated PU, wet-zone grade in bathrooms, heated-floor variant over UFH. A wall sealer on a floor scratches white within months.
- Programme — realistic minimums are 10–14 working days for an open-plan floor including cure stages. Quotes promising a week are skipping cure time, and the toolkit article shows what proper process looks like day by day.
- VAT — included or on top. On a £10,000 floor that's the difference between comparing £10,000 and £12,000.
If you're pricing a specific floor, the room-by-room budgets in the cost guide will get you to a realistic number before anyone visits — and a survey turns it into a fixed quote.
