The storage area in your loft can become a useful living space, adding to your home’s value and providing extra room for your growing family.

Average Cost of a Loft Conversion in Edinburgh

The average cost of a loft conversion in Edinburgh varies depending on the type chosen and the amount of structural work involved.

Velux Loft Conversion

A Velux or rooflight conversion costs between £25,000 to £40,000depending on size, specification and finish. This is the cheapest option for most homeowners as there are no major structural alterations to the roofline.

Dormer Loft Conversion

Dormer conversions offer increased headroom and more floorspace with the box-like extension fitted into the roof slope. Average prices range from £40,000 to £60,000depending on size and level of finish.

Hip-To-Gable Loft Conversion

A hip-to-gable conversion involves lifting the roof slope on the side of the property vertically and extending the gable wall upward. The increased construction and structural work means that this type of conversion costs around £45,000 to £65,000.

Mansard Loft Conversion

Mansard conversions are most often carried out on period properties where the roof is extended to a 72 degree angle. These steeply sloped roof sides effectively form walls which provide the extra space inside. Due to the extent of the structural alterations, the cost of a mansard conversion is around £50,000-£75,000or more.

Loft Conversion with En-Suite

For those who want to add a loft conversion with an en-suite to their Edinburgh property, the cost will be between £40,000and £60,000. However, the final price will depend on the level of finish as well as the size of the loft.

L-Shaped Dormer Loft Conversion, Where Suitable

An L-shaped dormer is formed when two dormers are built at right angles to each other on the roof. The effect is extensive living space, often providing two bedrooms and an en-suite. Due to the extra materials, labour and timescale, prices range from £50,000 to £80,000or higher depending on finish quality.

Factors Affecting Loft Conversion Costs

There are many factors that affect the final cost of a loft conversion in Edinburgh.

Type of Loft Conversion

The conversion type impacts the cost, with Velux conversions being the cheapest and mansards the most costly.

Size of the Loft

Roofspace size is a major cost contributor, in terms of materials, labour and fitting out.

Existing Roof Structure

Truss roofs cost more to convert than a traditional cut roof, with extra materials, time and labour needed.

Roof Pitch and Available Head Height

The pitch of the roof and available head room impact conversion costs with extra work necessary for some lofts to make the build feasible.

Whether Steel Beams Are Needed

Most loft conversions require 2 - 3 steel beams to support the floor and ridge, only rarely are timbers used instead.

Staircase Installation

The staircase affects costs with softwood winder staircases being the most affordable and bespoke metal stairs costing more.

Insulation and Ventilation

Type and quality of insulation and ventilation options have an impact on the budget.

Electrical Work

Loft size and quality of fittings will impact electrical costs.

Plumbing Work

Plumbing costs are incurred when including a bathroom as part of the conversion.

Adding a Bathroom or En-Suite

Adding an en-suite to the loft increases your material and labour budget.. The level of finish will also impact the final price.

Quality of Fixtures and Finishes

The level of finish and quality of fixtures affects your outlay.

Scaffolding

The number of scaffolding sides impacts the cost of this essential loft conversion service.

Waste Removal

Waste volume will directly influence how many skips you’ll need and the cost of hire.

Access to the Property

Poor access adds to labour costs, as when deliveries are difficult materials need to be manually unloaded.

Parking or Access Restrictions

Difficult or expensive parking for trades and delivery vehicles adds to your outlay and access restrictions can impact timescales.

Labour Rates in Edinburgh and Surrounding Areas

The cost of labour in Edinburgh tends to be more expensive than other parts of Scotland.

Loft conversion costs vary significantly as not all properties are the same. For example, a straightforward conversion with good head height and easy access typically costs less than a project that requires major structural alterations.

Many properties in Edinburgh incur extra costs due to their age. Older structures, those in conservation areas or with restricted access, can push loft conversion prices up. The degree of weather exposure and shared party wall issues also often lead to greater outlay.

Don’t forget that good insulation, adequate ventilation and sound roof condition are some of the most important and fundamental aspects of a successful loft conversion.

Loft Conversion Types and Costs

There are different types and styles of loft conversion with varying costs, as follows:

Velux Loft Conversion

A rooflight or Velux loft conversion is the least expensive and most straightforward. As no major alterations are needed beyond installing the rooflights, costs range from £25,000 to £40,000.

Dormer Loft Conversion

Rear and side dormer conversions increase the headroom and usable floorspace in the loft. The addition of the box-like extension to the roof slope means that costs are increased, typically to between £40,000and £60,000.

Hip-To-Gable Loft Conversion

Major structural work is needed to create a hip-to-gable loft conversion and this adds to the cost. Prices range from £45,000 to £65,000or more depending on property size and level of finish.

Mansard Loft Conversion

Potentially the most complex type of loft conversion, a mansard involves significant work to the roof. Costs in Edinburgh therefore range from around £50,000to more than £75,000.

L-Shaped Loft Conversion

Creating two dormers to form an L-shaped loft conversion requires a lot of material, labour and time. Prices are reflected in the amount of work needed and are between £50,000and £80,000.

Additional Costs to Consider

Other costs connected to the loft conversion that you need to think about include:

These additional costs can significantly add to the final price of the loft conversion, particularly if you want a fully finished habitable space rather than just a basic usable loft room.

Do You Need Planning Permission for a Loft Conversion in Edinburgh?

Most Edinburgh loft conversions fall under permitted development rights. However, this depends on the individual property, scale of the work and whether the roofline is being altered and by how much.

Other properties may require planning permission, including:

• Mansard conversions
• Larger roof extensions
• Flats or tenement properties
• Homes in conservation areas
• Listed buildings
• Properties with previous extensions
• Designs that significantly alter the roof shape or appearance

Regardless of whether planning permission is needed, you will still require a building warrant and building standards approval. If you’re unsure what you need for your project, contact the City of Edinburgh Council or your local planning authority before moving forward.

How Long Does a Loft Conversion Take?

The average timeline for a loft conversion is:

• Velux loft conversion: around 4–6 weeks
• Dormer loft conversion: around 6–8 weeks
• Hip-to-gable conversion: around 8–10 weeks
• L-shaped loft conversion: around 8–12 weeks
• Mansard conversion: around 8–12 weeks or longer
• Loft conversion with en-suite: may take longer depending on plumbing and bathroom installation

Timescales vary depending on the planning requirements, building warrant approval, extent of structural work, site access and level of finish. If a bathroom is included, this adds to the time the build takes and of course, the weather can always play a part in delaying work.

Benefits of a Loft Conversion

• Creates extra living space
• Can add an extra bedroom
• May increase property value

• Makes use of unused roof space
