Types of Loft Conversions and Their Costs
Here you can find a cost breakdown of different types of loft conversions:
Roof Light Conversion / Velux Loft Conversion
- Cost: £15,000 - £25,000
This is the most straightforward and cost-effective type of loft conversion. It involves adding roof light windows (Velux windows) and reinforcing the floor without making significant changes to the roof structure. It's suitable for properties with large existing loft space.
How to Convert Your Loft: Dormer Loft Conversion
- This Will Cost Around £30,000 - £50,000
A dormer loft conversion adds a dormer window that projects vertically from the roof slope, creating additional floor space and headroom. It’s a versatile option that suits most UK homes, including terraced houses, and can significantly increase usable space.
Hip to Gable Loft Conversion
- Cost: £40,000 - £60,000
A hip-to-gable conversion involves extending the sloping side of the roof (hipped end) to create a vertical gable wall. It’s ideal for semi-detached and detached houses with a hipped roof, providing more internal space and a more spacious feel.
Mansard Loft Conversion
- Cost: £45,000 - £70,000
A mansard conversion involves altering the entire roof structure to create a flat roof with steeply sloping sides. It’s a more complex and expensive option but offers the most additional space, often turning an attic into a full upper storey. Suitable for many property types, especially in urban areas.
Modular Loft Conversion
- Loft Conversion Cost: £55,000 - £70,000
Prefabricated loft conversions built off-site and then craned into position. This method can reduce on-site disruption and construction time. It's suitable for properties with enough access and where quick installation is a priority.
Bungalow Loft Conversion
- Cost: £20,000 - £50,000
Transforming the attic space in a bungalow is an excellent way to create additional living space without expanding the property’s footprint. Depending on the design and structural limitations of the property, various types of conversions can be considered, such as Velux, dormer, or Mansard conversions.

Additional Costs to Consider in a House Loft Conversion
Careful planning and budgeting for any additional costs can help ensure your loft conversion project stays on track and within budget. Don't get surprised and remember about those when converting a loft in your house.
Managing Loft Extension: Building Control Fees
Ensuring compliance with building regulations is crucial. Fees for building control inspections and approvals can add to the overall cost. The cost can vary depending on the complexity and scope of the project.
Waste Removal
The process of an attic conversion generates waste, including old insulation, roofing materials, and general construction debris. Hiring a skip or waste removal service will be an additional cost to factor in.
Basic Loft Conversions with Insulation Upgrades
Enhancing the insulation of the loft is often necessary to meet current building regulations. This can include floor, wall, and roof insulation to improve energy efficiency.
Calculating Accurate Loft Conversion Cost: Interior Design and Decoration
Once the structural work is completed, the interior will need decorating. Costs for painting, wallpapering, and other finishes can vary widely depending on the chosen materials and the complexity of the design.
Furnishing and Fittings
Outfitting the newly converted loft with furniture and fixtures, such as wardrobes, beds, and lighting, will add to the overall expenses. The cost can differ depending on the loft conversion ideas you'd like to apply.
Heating and Cooling Systems
Extending the existing heating system to the loft or installing new radiators, underfloor heating, or air conditioning units can increase costs. Ensuring the loft space is adequately heated and cooled is essential for comfort.
Fire Safety Measures
Compliance with fire safety regulations is mandatory. This might involve installing smoke alarms, fire doors, and ensuring proper escape routes, all of which can incur additional costs.
VAT
Most loft conversions are subject to VAT, typically at 20%. Ensure this is factored into your budget, as it can significantly impact the overall cost.
Contingency Fund
It's advisable to set aside a contingency fund of 10-15% of the total budget to cover unexpected expenses or changes during the project.
Additional Costs to Consider in a House Loft Conversion
- Obtain Multiple Quotes from Experts and Architects for a Loft Conversion: Get at least three quotes from different contractors to compare prices and services.
- Plan Thoroughly: Detailed planning can help avoid unexpected costs. Consider all aspects, including design, materials, and finishes.
- Consider Permitted Development: Many loft conversions can be done under permitted development rights, avoiding the need for planning permission and saving time and money.
- Set a Realistic Budget for a New Loft: Include a contingency fund for unexpected expenses. A 10-15% buffer is advisable.
- DIY Where Possible: If you have the skills, consider doing some finishing work yourself, such as painting and decorating.
- Check Contractor Credentials: Ensure your contractor is experienced in loft conversions and check their references and credentials.
- Invest in Quality: While it might be tempting to cut costs, investing in quality materials and workmanship can save money in the long run by reducing maintenance and repair costs.
