A loft conversion and loft boarding are two popular ways to utilize attic space, but they serve different purposes. At Get Rapid Plans, London, we help homeowners make the right choice based on their needs. Here’s a 10-point comparison to guide you.
1. Purpose of the Project
- Loft Conversion: A loft conversion transforms an underutilized attic into a fully functional living space, such as an extra bedroom, home office, or entertainment area. It significantly increases your home’s usable space and property value.
- Loft Boarding: Loft boarding is a more straightforward solution that provides a stable storage area by installing wooden boards over the existing joists. It’s ideal for storing seasonal items, suitcases, or household belongings without making major structural changes.
2. Structural Changes
-
Loft Conversion: This process involves major structural modifications, which may include:
✔ Raising the roof or altering the pitch (in some cases)
✔ Adding dormers or Velux windows for natural light
✔ Installing staircases for safe access
✔ Upgrading insulation and fire safety measures
✔ Reinforcing the floor to support additional weight -
Loft Boarding: Loft boarding requires minimal structural work and typically includes:
✔ Laying high-quality boards over existing joists
✔ Installing loft legs or a raised system to maintain airflow and avoid compressing insulation
✔ Adding a drop-down loft ladder for easy access
Because loft boarding doesn’t alter the roof structure or add significant weight, it’s a much simpler and quicker process compared to a full loft conversion.
3. Cost Differences
-
Loft Conversion: Due to the level of work involved, a loft conversion is a more substantial investment, with costs typically ranging from £20,000 to £60,000+, depending on:
✔ The type of conversion (Velux, dormer, hip-to-gable, or Mansard)
✔ The size and layout of the space
✔ The complexity of structural modifications
✔ Interior finishes and customization -
Loft Boarding: Loft boarding is a much more affordable option, with costs typically between £500 to £3,000. Prices depend on factors such as:
✔ The size of the loft area to be boarded
✔ The quality of materials used
✔ Whether insulation upgrades or access ladders are included
While a loft conversion is a long-term investment that increases property value, loft boarding is a cost-effective solution for homeowners who need extra storage without committing to a full conversion.
4. Planning Permission
-
Loft Conversion:
✔ Most loft conversions fall under permitted development rights, meaning you don’t need planning permission if the work stays within certain limits (e.g., not extending beyond the highest part of the roof).
✔ However, planning permission is required if:- You live in a conservation area or a listed building.
- The conversion includes a Mansard extension or significant structural alterations.
- Your plans exceed 40m³ for terraced homes or 50m³ for detached/semi-detached homes.
-
Loft Boarding:
✔ Usually does not require any planning permission as it does not involve external alterations or major structural changes.
✔ However, if you live in a listed building, you should consult your local planning authority before making modifications.
5. Building Regulations Compliance
-
Loft Conversion:
✔ Must comply with UK building regulations, covering:- Structural Integrity: Ensuring floors and walls can support the added weight.
- Fire Safety: Installing fire doors, smoke alarms, and a safe escape route.
- Insulation & Energy Efficiency: Meeting the required U-values for thermal insulation.
- Soundproofing: Minimizing noise transfer between floors.
-
Loft Boarding:
✔ Generally does not require strict building regulation approval, but:- If the loft is being used for storage, it should be installed correctly and safely to prevent overloading joists.
- If you plan to use the boarded loft as a living space, it must meet structural and insulation standards similar to a loft conversion.
6. Impact on Property Value
- Loft Conversion: A well-designed loft conversion can significantly increase your property’s value. Studies suggest that a loft conversion can add 15-25% to your home’s resale price, making it one of the most profitable home improvements. This is particularly beneficial if you plan to sell in the future, as buyers are often attracted to homes with extra bedrooms or functional office spaces.
- Loft Boarding: While loft boarding improves storage capacity and organization, it has minimal impact on resale value. Since it does not add extra living space, it won’t significantly increase the asking price of your home. However, it can make your property more appealing to buyers looking for additional storage solutions.
✅ Best for increasing home value: Loft Conversion
7. Time Required for Completion
- Loft Conversion: The construction timeline varies depending on the complexity of the project. A simple Velux loft conversion can take 4-6 weeks, whereas a more extensive dormer, hip-to-gable, or Mansard conversion can take 6-8 weeks or longer. The process involves structural modifications, insulation, and finishing work, all of which require careful planning.
- Loft Boarding: Loft boarding is a much quicker process, usually completed within 1-2 days. It involves installing a raised boarding system over joists, ensuring airflow and insulation remain effective. The speed of installation makes it a great choice for homeowners needing immediate storage solutions.
✅ Best for quick installation: Loft Boarding
8. Energy Efficiency & Insulation
- Loft Conversion: When converting a loft into a livable space, proper insulation is required to comply with UK building regulations. This means installing floor, roof, and wall insulation, making the loft comfortable for year-round use. With high-quality insulation, you’ll enjoy lower energy bills and improved home efficiency.
- Loft Boarding: While loft boarding may provide some insulation benefits, it does not meet the standards required for a fully habitable space. If your home already has insulation between the joists, boarding can help retain some warmth, but it won’t make the loft suitable for long-term occupancy.
✅ Best for energy efficiency: Loft Conversion
9. Functional Use of Space
-
Loft Conversion: This is the ideal option if you need additional functional space in your home. Depending on your needs, a loft conversion can become:
- An extra bedroom (with or without an en-suite)
- A home office or study
- A playroom or entertainment area
- A guest suite or rental space (if legally permitted)
-
Loft Boarding: Primarily used for organized storage, loft boarding is perfect for storing:
- Seasonal items (Christmas decorations, winter clothing, etc.)
- Suitcases, boxes, and extra household goods
- Tools and DIY equipment
- Important documents and archives
While it improves accessibility and tidiness, loft boarding does not create additional living space.
✅ Best for maximizing functional space: Loft Conversion
