What are the Different Elements of a Loft Conversion?

 As previously mentioned, each element of a loft conversion comes with a unique price tag. When planning out finances, it can be easy to overlook the cost of certain conversion features. Naturally, it is also important to consider factors such as the cost of labour at the time, inflation and other factors such as quality of materials.

Below, we break down the expected cost of key elements of any loft conversion – noting areas of greater expense and going on to offer tips for reducing the cost of a loft conversion.

Stair Access

In order to create a loft conversion space, you must first enable access from the existing floors of the house. As with any feature, the cost of stairs is highly determined by the materials and style chosen. A fixed loft ladder may be suitable for those looking for a lower-cost option. However, as choices become more bespoke, a price increase should be expected.

You then need to consider the time and the work needed to install the stairs. Installing stairs within an existing stair case can be cheaper than reconfiguring room layouts and floorplans by removing walls.

A large portion of the heat that escapes from a property is through its roof. When building a loft conversion, insulation is a key element that makes a converted space fit for use. As a result, adding a loft conversion increases the insulation value of a property overall. Depending on the insulation material used, prices can vary.


Again, the cost of windows for your loft conversion will vary depending on window size, shape and glazing preference. Many loft conversion designs feature Velux-style windows, hip and gable windows, while others feature full-length windows depending on their shape.

The size of the window will play a key factor in how much additional support is required in the structure of the roof. Additional materials may be needed to support larger and heavier windows which will add to the costs of installation.

A key factor influencing roofing costs is the shape and style of your existing roof. Like with other features, opting for a more complex style will also impact the price. For example, transforming a hipped roof into a gable roof will cost more than creating a dormer-style roof.

In addition, reusing roof tiles where possible can save home owners a large amount of money in their conversion journey. During this process tiles are removed for cosmetic and structural work to be completed. The tiles are then reinstalled on the roof, accounting for the changes. This means you will either have tiles to spare or you will only have to buy a smaller quantity of new tiles.

It is important to discuss with a professional before the project as they can assess the condition of the existing roof tiles and then make an assessment for the project. Get in touch with our experts today.

What are the Common Unexpected Costs of a Loft Conversion?

For the majority of project managers, labour and construction are the given expenses of a loft conversion project. But what are some more unexpected costs of a loft conversion?


When it comes to developing a loft conversion, its location relative to London can play a role in the costs associated. As with many other financial balances, the costs of working in and around London are inevitably higher than in other parts of the UK.

Ecological Surveys

Another potential expense is ecological surveys. If your property is built on a site that is home to any protected species, an ecological survey may be required.


Skips are required for almost all construction projects, but these come with a lot of hidden costs. While the upfront cost of a skip is typically low, if you do not have a drive or land to place the skip you will need to apply for a road permit to store the skip on the road.

There permits vary from council to council and can cost to apply. They may need to be updated for each new skip you have. It is important to speak to a contractor or a local skip provider to understand the costs which might be involved.

Contingency Fund

Many families and project managers embarking on a project choose to set aside funds in case they find themselves sort of cash. Many experts recommend a contingency of 10% of total construction costs.

Where Can You Save Money on a Loft Conversion?

Keep things smalla smaller loft conversion calls for fewer materials and reduced building time, meaning the total cost of the project will likely fall.

Choose a simple design high-end finishes and complex design are likely to lead to higher material and construction costs. If you’re looking to keep your loft conversion costs down, a simplistic design and more minimalistic materials may be the solution.

Alternatively complete the project in phases, complete the outer shell of the conversion in an initial phase. Furnish and decorate the project in a second phase.
