What is Planning Permission?

Planning permission is a legal document that allows you to construct or alter a building within specific guidelines. It is a document granted by local councils in the United Kingdom that allows you to alter the exterior and interior of a property. It is important to note that, in some cases, planning permission may not be required. In the United Kingdom, planning permission is usually required for loft conversions, extensions, new builds and other alterations.

Do You Need Planning Permission for a Loft Conversion?

The answer to this question varies depending on the local council in which you are located. Generally speaking, most loft conversions require planning permission. However, it is important to note that there are some exceptions to this rule. Some loft conversions do not require planning permission if they meet certain criteria, such as being built within the existing roof space or not extending beyond the current roof line. Additionally, some loft conversions may be exempt from the requirement for planning permission if they are intended for certain uses, such as housing a single family.

If you do need planning permission for your loft conversion, the application process is relatively straightforward. Generally, the process involves filling out an online form with your local council. This form should include detailed drawings and diagrams of the proposed alterations, as well as an explanation of why you are applying for planning permission. Additionally, you may need to submit supporting documentation, such as a copy of title deeds, a copy of the property plan, and photos of the property.

Understanding Different Types of Loft Conversions

A loft conversion is an excellent way to add more space and value to your home without the cost and disruption of an extension. It involves converting an existing attic space into a fully functional room. There are several different types of loft conversions available, each with their own unique benefits and drawbacks.

Dormer Loft Conversions

Dormer loft conversions are one of the most popular types of conversions due to the amount of space they provide. This type of conversion involves extending the roof outwards, creating a box-like structure which provides additional headroom and space. The downside of this type of conversion is that it can be expensive, as it involves significant structural work.

Hip-to-Gable Loft Conversions

A hip-to-gable loft conversion is a great option for those with hipped roofs, as it involves extending the roof to form a gable-end. This type of conversion provides more headroom and space, as well as improved access. However, it can be expensive and disruptive, as the existing roof structure will need to be replaced.

Mansard Loft Conversions

Mansard loft conversions are one of the most expensive types of conversion, but they provide a great deal of additional space. This type of conversion involves extending the roof at the rear of the property, creating a flat roof which provides significant headroom. The downside is that they can be disruptive and costly, as they involve replacing the existing roof structure.

Velux Loft Conversions

Velux loft conversions are one of the simplest and most cost-effective types of conversion. They involve installing large windows in the roof, which provide natural light and ventilation. The downside of this type of conversion is that the windows can be difficult to access and maintain, and the space is limited due to the existing roof structure.

L-Shaped Loft Conversions

L-shaped loft conversions are a great option for those with an irregular-shaped loft space. This type of conversion involves extending the roof in two directions, creating a triangular-shaped space which provides additional headroom and space. However, this type of conversion can be expensive and disruptive, as it involves significant structural work.

Benefits of Loft Conversion

One of the most important benefits of loft conversion is that it can significantly increase the value of your home. According to recent studies, loft conversions in the UK can add up to 20% to the value of a property and up to 25% in London. Investing in a loft conversion is a great way to maximise the potential of your home and increase its value.


Another one of the benefits of loft conversion is the financial benefits it can bring. Loft conversions are generally cheaper than buying a new home or building an extension. Also, the cost associated with a loft conversion can be offset by renting it out or selling it in the future. This can be a great way to generate additional income and offset the cost of the conversion.

Loft conversions can also provide additional living space for a family. This is especially beneficial for growing families or those who need extra space for guests. A loft conversion can also be a great way to add extra bedrooms or a home office. This can be especially useful if you are looking to work from home or have a home business.

Additionally, loft conversions can also provide improved privacy. Loft conversions can be used to create a separate space for a family member, such as a teenage child or an elderly parent. This can be beneficial for both the family member and the rest of the household. It can also be used for a home gym or other recreational activities.

Finally, loft conversions can also improve the energy efficiency of your home. This is because loft conversions make use of existing space and do not require additional construction. This can significantly reduce your energy bills and help you save money in the long run. Furthermore, loft conversions can also make use of natural light and ventilation to reduce your energy costs even further.

There are several benefits to obtaining planning permission for your loft conversion. Firstly, it can provide legal protection should any disputes arise in the future.

Furthermore, planning permission can often expedite the process of obtaining other necessary documents, such as building regulations approval.

– The loft conversion will alter the roofline of the building

– The loft conversion will extend beyond the current boundaries of the building

– The loft conversion will involve the installation of windows or other openings on a wall that faces a highway
