- Additional decoration & interior fittings: High-quality fittings, such as ensuite rooms, raise costs.
- Velux Window Accessories: Accessories like shades, remote controls, and rain sensors can increase conversion costs.
- Use of space: The converted loft's intended use (e.g., bathroom, kitchen, or bedroom) influences the cost. Kitchens and bathrooms typically require a more significant investment because of plumbing and specialised fixtures.
Planning Permissions and Building Regulations: Depending on your location and project scope, you might need to get planning permission or comply with specific building regulations, which can add to the cost.
Structural Modifications: The budget will increase if your conversion requires significant structural changes, such as reinforcing the roof or floor.

- Fire Safety: Windows must be large enough to allow safe escapes and rescues during fires, adhering to Part B (Fire Safety), which covers fire-resistant staircases and pathways.
- Sound Insulation: Construct soundproof barriers between converted spaces and adjacent areas according to Part E (Resistance to Sound Passage). Velux noise-reduction windows meet these standards.
- Insulation: Thermal performance standards for energy efficiency must be met, according to Part L (Conservation of Fuel & Power).
- Ventilation: Proper loft ventilation is required under the 2010 regulations (Part F).
- Light & Glazing Safety: Use reinforced glass for Velux conversions to minimise injury risks following Regulations Part N & K (Glazing Safety).
