How long will a loft conversion take?
On average how long will a loft conversion take to complete?
Answer:
The timeline for a typical loft conversion can vary, but on average it takes anywhere from 6 to 8 weeks for a standard loft conversion project.
However, the exact duration depends on several factors:
- Size and complexity – Larger, more complex loft conversions with dormers, hip-to-gable extensions, or structural changes will take longer than a simple room-in-roof conversion.
- Access – If there are tight access constraints to get materials into the loft space, it can slow progress.
- Planning approvals – If planning permission is required for the conversion, the approval process can add several weeks or months before work can even begin.
- Weather conditions – Bad weather can cause delays, especially during roofing and exterior work stages.
- Additional work – If the project scope expands to include en-suite bathrooms, staircases, plumbing, electrical work etc., it will extend the timeline.
A basic breakdown would be:
- 2-4 weeks for preparatory work like securing permissions, scaffolding erection, removing existing roof
- 2-3 weeks for structural work like installing steel beams, floor joists, staircase
- 1-2 weeks for roofing work with dormers, windows, weather-tightness
- 2-4 weeks for interior work like plasterboarding, plumbing, electrics, flooring
So in an ideal scenario with no delays, a straightforward loft conversion may take 6-8 weeks from start to finish. But it’s wise to factor in potential delays and plan for up to 3-4 months for more complex projects.
