Looking to extend your property with a loft conversion? Budget is a huge part of your decision so we’ve put this handy guide together to help you figure out the cost.
Loft conversions build into your loft or attic space to give you additional rooms and add value onto your property. They are flexible in style depending on the size and shape of your property. Your contractor can either add a structure on top of your existing roof or completely rebuild it to add more usable space.
The cost of getting a loft conversion can vary widely, but to give you a general idea here’s a breakdown of the average price based on local UK contractors:
| Average cost (in total) | £25,000 |
| Minimum cost (in total) | £15,000 |
| Maximum cost (in total) | £50,000 |
Before you go ahead with a loft conversion, you need to think about what would work best for your budget and the property. The good news is that planning permission is not normally required to install a loft conversion. Here are some of the other top considerations you’ll need to factor in:
Type of loft conversion
Your property type
Your location
Loft conversions vary dramatically in price depending on the type you choose. However, this should be seen as a plus as it means even on a smaller budget you can still create a warm and inviting living space at the top of your home. Cheaper loft conversions such as dormers focus more on adding more natural light rather than changing the structure and layout of the room, as you would find in a hip to gable conversion.
Not all loft conversions are created equal. The type you choose will depend on your property type as well as what you want to achieve. For example, you may want to install a bedroom and an ensuite or simply increase the usability of the space by adding more natural light.
Let’s have a more detailed look at the different types of loft conversions and their prices:
| Type of loft conversion | Highest average price | Lowest average price |
| Dormer loft | £40,000 | £20,000 |
| Mansard loft | £75,000 | £45,000 |
| Hip to gable loft | £50,000 | £42,000 |
Dormer lofts are often referred to as ‘box conversions’ due to the shape they create on top of your roof. Compared to other loft conversion types, dormers are by far the cheapest. They start at around £20,000, though the price could be even cheaper for smaller roof spaces.
There is typically far less work involved as you are simply adding a structure on top of the roof space, rather than rebuilding or remodelling the outside walls.
Most homes have a sloping roof which would prevent you from making full use of your loft space even when converted. A hip to gable loft conversion removes the slope and builds upwards so that the wall remains straight on one side until it reaches the top of your roof.
Hip to gable loft conversions is middle of the road when it comes to the price. They cost an average of £42,000 and can go up to £50,000, so they’re a significant investment compared with a dormer loft conversion. However, they are more consistently priced than any other loft conversion type.
Taking inspiration from 17th-century French architecture, Mansard lofts add on a brand new roof to your home. They are built flat and upwards as opposed to being sloped which will give plenty of usable space.
Mansard loft conversions are the most expensive conversions, starting at £45,000. While Mansard conversions are traditionally French in style, they can use glass and other modern materials that can push the budget up to £75,000, making them far more expensive than other loft conversion types. However, the stunning finish they give will undoubtedly increase the value of your home, so they are well worth it if within budget. Your property type and personal taste will greatly influence which style you go for.
Homes that are built before the 1960s tend to be easier to convert as they have fewer roof trusses. This could make the project slightly cheaper than installing a loft conversion in a newer home. Newer homes may also require steel beams which will cost more than homes that have a better starting shape.
That being said, when done well, and in accordance with building regulations, a loft conversion will add an average of 15% to the value of your property. This figure is closer to 20-25% in London, so any initial spending could be recouped in the sale price if you do decide to sell one day.
Like most services, location is another key factor influencing price. You’re likely to spend more in London compared to elsewhere in the UK.
| Location | Maximum cost | Minimum cost | Average cost |
| Outside London | £60,000+ | £5,000 | £25,000 |
| Inside London | £75,000+ | £8,000 | £41,500 |
The size of your home and the available roof space
The spec of the finish and the materials used to achieve this
Whether you are also adding a bathroom
A quote for a loft conversion might seem as steep as the roof you are looking to change, but that’s because there is a lot involved behind the scenes. The price may include planning permission if applicable, but it will certainly include surveyor fees. After all, your loft conversion needs to be both practical and safe. Then there are the interior jobs too, such as removing old roof trusses, installing windows not to mention insulation.
Finally, you should also factor in the cost of any architects or interior designers. If you are installing a bathroom, this could add anywhere from £5,000 to £10,000 to the project depending on the size and spec. For bedrooms or offices, you’ll also need to think about the cost of decorations and furnishings once the building work has been completed.
If you want to add space and value to your home and you’re not keen on moving, then a loft conversion is certainly worth it. From growing families to home offices, and even landlords looking to increase their yields - a loft conversion has endless benefits. The best loft conversions are carried out by trusted, regulated companies. These will add the most value to your home, especially when executed to a high standard.
