Self-Build Screeding Guide: Everything You Need to Know

For self-builders in the UK, screeding is often one of the most confusing parts of the build. You know you need it, but understanding what type to use, when to schedule it, and how to get a fair price takes time you may not have. This guide answers the most common questions self-builders ask us.

When Should Screeding Happen in the Build Programme?

Screeding should happen after the building is watertight (roof on, windows and external doors fitted), all first fix services are complete (UFH, underfloor pipework, electrical conduits), and the substrate has been inspected and prepared. Do not screed before the building is watertight — rain ingress will damage fresh screed and significantly extend drying time. Allow 4–8 weeks after screeding before floor finishes, depending on screed type and depth.

Which Screed Is Best for a Self-Build?

For most self-builds, liquid anhydrite screed is the best choice. It is faster to install (an entire ground floor can be done in a day), achieves a flatter finish as standard, and is ideal for UFH — which is now standard in most self-builds. The main consideration is minimum area: most liquid screed contractors have a minimum charge equivalent to around 80–100m². For smaller areas, sand and cement may be more cost-effective.

How Much Will Screeding Cost on My Self-Build?

A typical self-build ground floor of 120–180m² at 35mm liquid screed over UFH will cost approximately £1,800–£3,500 including pump hire. This is one of the most cost-effective elements of the build and should not be skimped on — a poor screed will cause floor finish failures that cost far more to put right.
