How much does a loft conversion cost?

Converting a loft is one of the fastest and most affordable ways to enhance the space of your home.

When trying to work out how much a UK loft conversion costs, different factors must be taken into account. These include:

  • The space you are working with. How big is your house? What kind of roof structure does it have (for example, it is a sloping roof, or is it flat?). Is it a detached house, or does it share a wall/walls with neighbours?
  • Structural considerations. What structural requirements will need to be taken into consideration (for example, does your loft have beams, joists, or any other prominent features that need to be considered?)
  • Your neighbours and planning permission. Do you share a wall (called a ‘party wall’) with anyone else? How will this affect your planning permissions and the type of loft conversion you are able to go forward with?
  • The purpose of the loft conversion. Why are you considering converting your loft? What do you intend to use the extra space for (will it be a storage, work or living space for instance) and how will that impact what you need the space to look like when it’s finished?

Our useful calculator will take all these factors into account when working out your personal loft conversion cost estimate.

What are the cheapest types of loft conversion?

There are four main types of loft conversion. These all involve different processes, and have varying costs, with some being more cost-effective than others. The four main types of conversion are as follows:

  1. Dormer loft conversions. This is one of the most common types of loft conversion chosen by homeowners. This process involves a structural extension that projects vertically from the roofing of the house. It is often referred to as a simple flat roof dormer extension. This is one of the most cost-effective loft extension types as it is a straightforward process than adds more space to the existing roof area.
  2. Mansard loft conversions. This extension is constructed by raising the party wall (a wall shared with a neighbour) and rebuilding a slanted roof onto it. This can take more time, as it involves further planning permissions. It is most popular with people living in terraced houses who want to create more loft space. However, it is generally the most expensive type of loft conversion.
  3. Hip-to-gable conversions. These types of loft conversions are most commonly used by people who own end-of-terrace houses. They involve the roof space being extended horizontally, with the ceiling joists extended outwards. They are usually cheaper than mansard conversions, but a more expensive option than dormer.
  4. Internal conversions (such as roof light loft conversions). These are usually the most cheap loft conversion types. In fact, estimates put this process at 25% cheaper than other types of roof extension. This is because construction does not involve altering or expanding the structures of your roof itself. Instead, windows are usually added to provide more natural light, or skylights are added. This is faster and requires less resources, so the average costs are lower.

What is the cost of a dormer loft conversion?

A dormer loft conversion, which is the most common kind of loft extension, involves your roof space being extended with the use of a vertical structure. This then sits on the top of your roof.

It is an extremely popular option, as it is a more straightforward and less expensive process than other types of loft conversion (such as a mansard or hip-to-gable) and it provides you with more room or loft space.

The average loft conversion cost for a UK dormer extension is around £26,000 in total. But a dormer windows roof conversion can cost anything from £7,000 to £50,000 depending on the size of your property and your needs.

If you are asking yourself, ‘how much does a loft conversion cost’ and you want to know more about dormer windows and extension prices, use our calculator to find out a realistic estimate. Or, call us directly on 01625 885 030 to arrange a consultation with a loft conversion specialist.

What are the small loft conversion costs?

Small loft conversion costs are often lower than larger-scale projects. They can range from £5,000 to £30,000 (but this is dependent on different factors). But while the area dimensions of your house, loft and roof will be key factors in your cost estimates, there are other considerations to bear in mind. For example, our calculator also considers factors such as your budget, deadlines and plans for the space. These are all elements which will impact the final cost of a UK loft conversion.

How much would a loft conversion cost me if I wanted to add stairs?

When calculating the price of a loft conversion, stairs – or plans to add them – are a very important factor.

If you want to add stairs into your plans for a loft extension, this will impact the total conversion costs. This is because building stairs requires more resources and time than other types of home conversions.

Our loft conversion calculator takes your plans to include stairs in your designs into consideration when creating an average cost estimate for converting your loft.

Do I need planning permission for a loft conversion?

You do not usually need planning permission for a loft conversion, as this falls within normal permitted development rights.

In certain cases, you may need to apply for planning permission when undertaking a loft conversion. This is often the case if your plans exceed certain parameters or if your plans for converting your loft impact your neighbours’ property. It can also be the case if you need to factor in special building regulations, such as if your building is listed.

If you need to apply for planning permission, this usually involves paying fees to your council or local authority. This will impact your total loft conversion cost.

Use our cost calculator to determine a realistic estimate of how much it will cost you to convert your loft space.

What other elements do I need to factor into to finding out how much my loft extension costs?

Loft conversion specialists analyse different factors when putting together a quote.

Things you should consider when trying to determine the cost of converting a loft in the UK are:

  • How much building control you have (whether you share a party wall with a neighbour or have unlimited scope to extend your property)
  • How much you want to extend your space (for example, do you want more headroom, more floor space or do you just need building work to add windows for extra natural light?)
  • The intended use of the new room/space (will you need it be a habitable room or is it simply for storage. If you intend it to be a bedroom rather than a living room, will you need to install plumbing for an ensuite?)

Generally, converting your loft in the North West is much cheaper than in other areas of the UK (such as London and surrounding areas).
