Liquid screed is a modern flooring material used to create smooth and level floor surfaces. It is pumped onto the floor as a liquid mixture, most commonly gypsum based, which naturally spreads across the area before setting. Because the material flows freely and levels itself, it normally produces a flatter surface than traditional sand and cement screed.
This makes it particularly useful for large properties, complicated floor layouts, and projects installing underfloor heating systems. With professional pumping equipment, londonfloorscreeding.co.uk can place screed quickly and evenly across construction sites throughout London.
Benefits of liquid screed
One of the key advantages of liquid screed is how well it works with underfloor heating. The flowing material surrounds heating pipes and insulation layers, creating a dense screed that transfers heat efficiently throughout the floor.
Because the screed levels itself naturally, the installation process is quicker and involves far less manual work compared with traditional screeds. This helps maintain consistent results across larger areas and keeps site work cleaner.
Once cured, liquid screed forms a strong base with minimal shrinkage, which helps reduce the risk of cracking. The finished surface provides an ideal foundation for tiles, stone, timber flooring, and other finishes commonly used in modern properties.
What affects the cost per m²?
Several factors influence the price of liquid screed installation.
Project size
Larger floor areas generally reduce the cost per square metre because equipment and labour are already on site. For example, a 2000m² pour may cost around £10 per m², while a smaller 100m² project may be closer to £16 per m².
Thickness of the screed
The required depth will affect how much material is needed. Floors with underfloor heating normally require 50–75mm of screed, while depths of around 100mm will increase costs.
Access to the site
Projects in central London or sites with restricted access may require longer pump runs or additional setup time.
Type of screed used
Standard sulphate screeds are widely used, but fast drying or high performance cement based options are available and tend to cost more.
Preparation work
Extra work such as insulation installation, surface preparation, or reinforcement may also influence the final price.
Typical UK prices
Across the UK, pumped liquid screed installations often fall within the £20s per square metre. Material only estimates are usually around £18–£24 per m², meaning installed costs commonly sit in the low to mid £20s per m².
Very small projects under around 40m² can cost more due to equipment setup and labour requirements. The most accurate way to determine the price is to request a quotation. londonfloorscreeding.co.uk provides clear surveys and transparent pricing for projects across London.
Other options
Traditional sand and cement screed
This is often cheaper in terms of material cost but requires thicker application and takes longer to dry. It is generally used on simple floors without underfloor heating.
Self levelling concrete
Self levelling concrete provides an extremely flat finish and cures quickly, which can help speed up construction programmes. However, it is often more expensive than standard screeds.
