What Type of Loft Conversion is Cheapest?
If budget is your primary concern, certain loft conversion types offer more cost-effective solutions:Velux/Rooflight Conversion
The most economical option, typically costing between £20,000-£30,000 in Oxford. These conversions involve installing roof windows without altering the existing roof structure, making them:
- Quicker to complete (usually 4-6 weeks)

Do I Need Planning Permission for a Loft Conversion?
Many loft conversions in Oxford fall under ‘Permitted Development Rights,’ meaning they don’t require formal planning permission. However, this depends on several factors:Permitted Development Criteria

- No extension beyond the existing plane of the roof on the principal elevation
- No higher than the highest part of the existing roof

Planning Permission Required If:

- Your conversion exceeds permitted development limits
- You’re planning to alter the roof height or shape significantly
- Your property has already used its permitted development rights
