Average Cost of a Loft Conversion
The cost of a loft conversion in the UK typically ranges from £20,000 to £60,000, depending on the type of conversion:
- Velux (Rooflight) Loft Conversion – £20,000 to £30,000. The most cost-effective option, as it requires minimal structural work and mainly involves adding windows to the existing loft space.
- Dormer Loft Conversion – £35,000 to £50,000. A popular choice that extends the roof to create more headroom and usable space, making it ideal for adding a bedroom or office.
- Hip-to-Gable Loft Conversion – £40,000 to £55,000. Suitable for semi-detached or detached houses, this conversion extends the sloping side of the roof to create a larger living area.
- Mansard Loft Conversion – £45,000 to £60,000+. The most extensive type of conversion, involving significant structural changes to maximise space. It is often seen on terraced properties.
Additional Costs to Consider
- Architect and Structural Engineer Fees (£1,500 – £3,500). Essential for planning and ensuring the loft conversion meets building regulations.
- Planning Permission (if required) (£200 – £500). Most loft conversions fall under permitted development, but larger alterations may need planning approval.
- Building Regulations and Inspections (£500 – £1,500). Covers certification to ensure the conversion meets safety and structural standards.
- Staircase Installation (£1,000 – £5,000). A well-designed staircase is crucial for accessibility and can impact the layout of your home.
- Insulation and Heating (£1,000 – £3,000). To ensure the loft space is energy efficient and comfortable year-round.
- Electrical and Plumbing Work (£1,500 – £5,000). If adding an en-suite bathroom or rewiring is required, costs will increase accordingly.
- Interior Finishing (£5,000 – £10,000). Includes plastering, flooring, painting, and built-in storage solutions.
How to Save Money on a Loft Conversion
- Choose a Simpler Design – A Velux conversion is the most budget-friendly option.
- Plan Ahead – Avoid costly alterations by finalising the design before construction begins.
- Use a Reputable Contractor – While it may be tempting to go for the cheapest quote, quality workmanship will prevent costly repairs in the future.
- Check if You Qualify for Permitted Development – This can save on planning permission costs.
