Pumped vs hand-laid screed
Liquid Screed vs Sand-and-Cement Screed
One is poured and self-levels in a day, the other is barrowed and hand-floated over a week. Here's what that actually means for your programme, your UFH and your budget.

Sand-and-cement screed has been the default UK flooring sub-base for decades — a sand, cement and water mix, barrowed in, compacted and hand-floated in bays. It still has a place. But on almost every UFH job, and on most renovations with a tight programme, liquid screed has taken over for good reason.
The two aren't really competing on quality of finished floor once cured; they're competing on speed, flatness, depth and how well they suit modern heating systems.
Below is the comparison we give clients who assume sand-and-cement is the 'normal' choice and haven't priced liquid screed against it yet.
Sand-and-cement vs liquid screed, in numbers
~40m² vs 300–500m²
Coverage per day
SR2 vs SR1
Flatness achievable
65–75mm vs 30mm
Min. depth over UFH
5–7 days vs 24–48h

When each one is the right call
Sand-and-cement wins when…
- Very small or awkward areas not worth a pump mobilisation
- No UFH, no depth constraint
- A local trade is already on site and available
- Falls to gullies needed in a single hand-finished pour
Liquid screed wins when…
- Any UFH is in the build-up
- Programme has no room for a week of hand-laying
- Large open-plan floor needs joint-free flatness
- Low overall floor build-up depth is required

Send your floor plan and we'll price liquid screed against a sand-and-cement alternative so you can see the real numbers side by side.
Cement-based liquid screed
- Flowing cement-based screed, not traditional sand and cement
- Suitable for tiles and wet areas
- Pumped and self-levelling
What doesn't change between the two
- Both need a correctly detailed DPM and perimeter isolation
- Both need adequate drying time before floor coverings go down
- Both can accept tile, LVT, carpet or engineered wood once dry
- Neither is a structural slab replacement — both sit on a sound sub-base
The decision test
If your floor area is under roughly 15m² with no UFH and a hand trade is already booked, sand-and-cement is a reasonable, low-fuss choice.
If UFH is anywhere in the build-up, or the area is larger than a single room, or the programme has less than a week of float in it, liquid screed wins on every practical measure — and usually on cost once labour days are counted properly.
