How much does a loft conversion cost in Cardiff?
As a 2025 guide, most homeowners in Cardiff pay somewhere between £25,000–£60,000 for a loft conversion. The biggest factors are conversion type (Velux, dormer, hip-to-gable, mansard), staircase position and structural work, and adding an ensuite or extra glazing. Getting two or three quotes is the best way to see a fair local price — which is exactly what our free matching service arranges.
Figures are a 2025 guide only — your matched installer will give you an accurate, no-obligation quote.
How long does it take?
In Cardiff, expect a typical loft conversion to take about 6–10 weeks once work begins.
- Check your head height. You generally need 2.2m at the highest point for a usable conversion.
- Plan the staircase. Access takes space from the floor below — design it in early.
- Consider building regs. Fire safety, insulation and stairs must meet regulations.
