How much does a loft conversion cost in Hillingdon?

A typical Hillingdon loft conversion works out at about £32,000–£77,000 in 2025. London is the most expensive part of the UK for building work, well above the national average — Greater London labour and materials are a real factor. Expect conversion type (Velux, dormer, hip-to-gable, mansard) and adding an ensuite or extra glazing to move the price most, along with staircase position and structural work. 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 Hillingdon, 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.
  • Consider building regs. Fire safety, insulation and stairs must meet regulations.
  • Think about light. Rooflights and dormers dramatically change how the room feels.
