What affects the price
- Scope of work. Cosmetic updates (painting, flooring) cost far less than structural changes (loft conversions, extensions).
- Property size. Costs are largely driven by floor area; typical London refurbs run £700–£1,500/m².
- Specification. High-spec finishes (Amtico flooring, bespoke joinery) significantly increase costs.
- Structural condition. Older London properties may have hidden issues (damp, asbestos, failing foundations) that add cost.
Frequently asked questions
Do I need planning permission for a house renovation?
Internal renovations generally do not require planning permission. Extensions, loft conversions, and changes to external appearance often do. LPG can advise on your specific project.
How long does a full house renovation take?
A full 2-bed flat refurb takes 6–12 weeks. Larger projects with structural work can take 3–6 months.
