Converting your loft into a living space can add valuable square footage and create an extra bedroom, office, or storage area in your home. However, loft conversions require careful planning and significant investment. If you’re considering a loft conversion, one of your biggest questions is likely – how much will it cost?
The cost of converting a loft can vary widely based on the size and layout of your space and the level of finish you desire. Generally, loft conversions fall into the £20,000 to £50,000 range, with the average cost being around £33,000. In this article, we’ll break down the key factors that influence the cost of your loft conversion in Glasgow so you can budget appropriately.
How Much Does a Loft Conversion Cost in the UK?
The cost of a loft conversion in the UK varies widely depending on various factors such as the type of conversion, the size of the loft, the complexity of the project, and the location of the property. Remember, these figures are approximate and can vary based on the specifics of your project. It’s always wise to get several quotes from different contractors and to factor in a contingency budget for unforeseen expenses. As of our last update, here’s a general idea of the costs involved:
- Basic Velux Conversion: The simplest and typically the most affordable option, a Velux conversion involves adding skylight windows without altering the existing roof structure. Prices for this type of conversion generally start from around £15,000 to £20,000.
- Dormer Conversion: A more involved project that includes extending the roof to add more headroom. For a dormer loft conversion, costs usually start from around £20,000 to £40,000, depending on the size and specifications.
- Hip-to-Gable Conversion: This is required for some properties with hipped roofs and involves changing the roof structure to increase space. Costs can range from £30,000 to £45,000.
- Mansard Conversion: The most extensive type of conversion, involving significant changes to the roof structure. Prices for mansard conversions can start from £40,000 and go much higher.
- Additional Costs: Besides construction, other costs include planning permission fees (if applicable), architectural services, building regulation fees, and interior finishing. If your conversion includes a bathroom, plumbing costs will also add up.
- Regional Variations: Prices can vary significantly across the UK, with conversions generally costing more in London and the Southeast.
Factors That Affect the Cost of a Loft Conversion
Several variables impact how much you’ll pay to convert your loft space into a usable room. The main factors that influence cost include:
Size of the Loft
The amount of square footage you’re converting is a major cost determinant. Materials and labour will be more for larger spaces. As a general guideline, loft conversions cost £1,500 – £2,500 per square meter.
Level of Finish
The quality of materials and fixtures you choose directly impacts the overall price. Basic conversions with budget finishes can be around £20,000, while luxury bespoke conversions with higher-end finishes can be £50,000+.
Structural Work
Some lofts require significant structural changes like dormer windows, stairs, strengthening floors, or moving load-bearing walls. These additions involve both materials and skilled labour, increasing costs.
Type of Conversion
Simple conversions staying within the existing roof space are cheaper. Conversions involving large dormers or complete roof reconfigurations are the most expensive.
Location
Construction costs vary across different regions of Scotland.

How to Save on Your Loft Conversion
If your budget is tight, there are ways to reduce the cost of your loft conversion:
- Work with an experienced loft conversion company instead of a general builder – they may offer package deals or have lower labour costs for standard jobs.
- Opt for Velux or dormer roof windows rather than a large dormer conversion. Roof windows minimize structural changes needed.
- Use ready-made stairs rather than spending on a bespoke staircase.
- Choose a basic, cost-effective finish like laminate flooring and paint versus higher-end finishes.
- Finish the conversion yourself – do the painting, trim work, etc. to only pay labor for the structural elements.
