Do I Need Planning Permission For A Conservatory?

How big can a conservatory be without planning permission in the UK? What is a conservatory legally in the UK? Can you build your own conservatory in the UK?

How much does a conservatory cost in the UK? Can a conservatory be used as a bedroom in the UK? Is a conservatory cheaper than an extension? Can you put a toilet in a conservatory?

These are common questions homeowners ask whenever they are planning a conservatory. With the ocean of information available, it’s easy to get lost and end up on the wrong side of building regulations.

In recent years, conservatories and home extensions have gained immense popularity in the UK. Many homeowners are opting for these additions to enhance their living space.

This trend is partly due to the rising cost of moving homes and the desire to maximise existing space. A conservatory can provide a beautiful, light-filled area that blends the indoors with the outdoors.

• Conservatories are versatile: They can be used as dining rooms, play areas, or simply a place to relax.
• Cost-effective: Compared to a full extension, a conservatory is generally cheaper and quicker to build.
• Adds value: A well-designed conservatory can add value to your property.

Understanding Planning Permissions

One crucial aspect of adding a conservatory is understanding planning permissions. In the UK, you may not need planning permission if your conservatory meets certain conditions.

These include:

• Size and Height: The conservatory must not exceed 50% of the land around the original house and must not be higher than the highest part of the roof.

• Location: It must not extend beyond the rear wall of the original house by more than three metres (for an attached house) or four metres (for a detached house).

• Width: The width of the conservatory must not be more than half the width of the original house.

However, different rules apply if your home is in a designated area, such as a conservation area or a national park. Always check with your local planning authority to be sure.

Building Regulations

While planning permission may not always be required, building regulations approval is a different matter. Building regulations ensure that the structure is safe, energy-efficient, and accessible.

They cover aspects like structural integrity, fire safety, and ventilation. Your conservatory must comply with these regulations, which might include:

• Insulation: Proper insulation to ensure the space is energy efficient.
• Safety Glazing: The use of safety glass in critical areas to prevent injuries.
• Electrical Work: All electrical installations must comply with safety standards.

Generally, adding a conservatory is covered by permitted development so you wouldn’t need to apply for planning permission.

Definition and Types of Planning Permission for a conservatory

A conservatory is a structure attached to a house, typically featuring a glass roof and walls. It serves as a transitional space between the home and garden, allowing for abundant natural light.

Conservatories are popular in the UK due to their versatility and aesthetic appeal.

There are several types of Planning Permission for a conservatory:

Victorian Conservatories

Known for their ornate design, bay front, steeply pitched roof, and decorative ridge details. Ideal for period properties.

The Victorian style adds a touch of elegance and historical charm, making it perfect for homes with a traditional look. The bay front creates a panoramic view of the garden.

Edwardian Conservatories

Characterised by a rectangular or square shape, providing maximum floor space. The simple, elegant design suits both traditional and modern homes.

The flat walls make it easy to furnish, and the pitched roof ensures plenty of natural light.

Lean-to Conservatories

Also called Mediterranean conservatories, these have a sloping roof and minimalist design. Perfect for homes with limited space.

They are often the most cost-effective option and can fit into awkward spaces, making them highly practical.

Gable Conservatories

Featuring a high, pointed roof, offering a grand and spacious feel. Great for creating a dramatic impact. The full-height windows allow for maximum sunlight and a sense of openness, which can make the space feel larger.

P-shaped Conservatories

Combining lean-to and Victorian or Edwardian styles, providing versatile space for multiple functions. They can create distinct areas within the conservatory, such as a dining area and a lounge space, offering flexibility in use.

Choosing the right type of conservatory depends on your home’s architectural style, available space, and intended use.

Uses and Benefits of Adding a Conservatory

Adding a conservatory to your home offers numerous benefits, making it a valuable investment.

A conservatory can serve various purposes:

Additional Living Space

Use it as a dining room, lounge area, or children’s playroom. This extra room can be a perfect spot for family gatherings, hobbies, or relaxation. It can serve as a flexible space that adapts to your lifestyle.

Garden Room

Enjoy your garden all year round, regardless of the weather. A conservatory allows you to experience the beauty of your garden even in winter, providing a warm and sheltered space to enjoy the view.

Home Office

Create a bright, inspiring workspace away from household distractions. The natural light and garden views can enhance productivity and well-being. This can be especially beneficial for those who work from home.

Entertainment Area

Host gatherings and parties in a unique, light-filled space. A conservatory can be an attractive venue for social events, offering a pleasant atmosphere for guests with the added charm of garden views.

Moreover, conservatories provide several key benefits:

Increased Property Value

A well-designed conservatory can add significant value to your property, making it attractive to potential buyers. Buyers often see a conservatory as a desirable feature, which can make your home stand out in the market.

Natural Light

Abundant natural light enhances your mood and reduces the need for artificial lighting, saving on energy costs. The influx of daylight can make the space feel more inviting and can contribute to a healthier living environment.

Connection to Outdoors

Enjoy the beauty of your garden from the comfort of your home, creating a seamless indoor-outdoor connection. This connection can improve your quality of life by providing a tranquil retreat and a closer connection to nature.

Versatility

Adapt the space to suit your changing needs. Whether you need extra space for a growing family or a quiet retreat, a conservatory can evolve with you. Its flexibility makes it a long-term investment that can cater to different phases of life.

Under UK law:

• Terraced and semi-detached homes can add single-storey extensions up to 6 metres from the rear of the original house WITHOUT planning permission.
• Detached homes can add single-storey extensions up to 8 metres from the rear of the original house WITHOUT planning permission.

However, for ‘larger extensions’ (over 3 metres for terraced/semi-detached homes and over 4 metres for detached homes). Further you must inform your local planning authority as the proposed work will be subject to the neighbour consultation scheme.

The conservatory must also comply with the following to be covered by permitted development:

• It does not extend from the front of the property
• It is a maximum height of 4 metres
• The roof ridge or top point is no higher than the existing house
• A side conservatory has a width of no more than half that of the original house
• The conservatory and additional outbuildings (sheds, summer house etc) do not cover more than half the garden

Permitted Development: A Breezy Path for Planning Permission for a conservatory

The good news is that many conservatories can benefit from permitted development (PD) rights. This means you may not need to submit a full planning application, saving you time and simplifying the process. Here’s what you need to know about permitted development for conservatories:

• Size Matters: Generally, single-storey conservatories up to a maximum of 25 cubic metres in volume and a maximum height of 4 metres can be built under permitted development, provided they meet other limitations.
• Location, Location, Location: PD conservatories typically cannot extend beyond the rear wall of your house or be built forward of the principal elevation (the front facade).

Understanding the Permitted Development Limitations

While PD offers a smoother path, it’s crucial to be aware of the limitations to ensure your conservatory complies:

• Half the Land Rule: The total area of extensions (including any previous extensions and the conservatory) cannot cover more than 50% of the original land surrounding your house.
• Material Matters: Some local authorities may have restrictions on materials used for conservatories under permitted development.
• Detached vs. Terraced or Semi-detached: The maximum size allowance for PD conservatories might differ depending on the type of property you have.

Planning Permission vs. Lawful Development Certificate

You probably don’t have permitted development rights in a conservation area. On a listed building or in an area of outstanding natural beauty. Check with your local planning authority. If you’re not sure whether or not you have any planning restrictions in place.

If your conservatory does come under permitted development . Then you can just start building. However, we recommend that you apply for a lawful development certificate. In order to prove that the work is covered by permitted development.

If your conservatory is not covered by permitted development, then you’ll need to apply for planning permission.

To apply for either a lawful development certificate or planning permission. On that you’ll need to submit an application to your local planning authority or via the Planning Portal online application service. (You don’t need to make the application yourself – Yoop can apply on your behalf so you don’t have to worry about it.

When Planning Permission Becomes Necessary

If your conservatory ambitions don’t fit neatly within permitted development criteria, you might need to apply for planning permission. Here are some scenarios where a formal application is likely required:

• Larger or Higher Conservatories: If your conservatory design exceeds the permitted development limits for size or height, you’ll need to submit a planning application.
• Closer to the Boundary: Building a conservatory very close to your property line might necessitate planning permission.
• Conversions and Special Features: If your conservatory involves converting existing structures or incorporates features like balconies, planning permission might be required.

Building Regulations

Building regulations in the UK are a set of standards that ensure buildings are constructed safely and efficiently. They cover various aspects of construction to ensure that buildings are safe, healthy, and sustainable.

These regulations are enforced by local authorities and must be adhered to during the planning and construction phases of any project, including conservatories.

The primary aim of building regulations is to ensure that buildings meet minimum safety and performance standards.

Moreover, building regulations contribute to the overall quality and longevity of the construction.

By meeting these standards, you enhance the energy efficiency and sustainability of the building, leading to lower running costs and a reduced environmental impact.

• Legal Protection: Compliance provides legal protection and prevents potential disputes with authorities or future buyers.

• Financial Savings: Avoiding penalties and costly corrections can lead to significant financial savings.

Enhanced Quality: Following regulations ensures a higher quality build, contributing to better living conditions and property value.

FAQs On Conservatories in the UK

• How big can a conservatory be without planning permission in the UK?

In the UK, you can build a conservatory without planning permission if it falls within permitted development rights. Generally, this means:

• The conservatory does not exceed 50% of the total area of land around the original house.
• It is no higher than the highest part of the existing roof.
• Single-storey rear conservatories extend no more than 4 metres beyond the rear wall for detached houses and 3 metres for other houses.
• Side conservatories are single-storey with a maximum height of 4 metres and less than half the width of the original house.

However, these rules can vary, so it is always wise to check with your local planning authority.

Do you need Planning Permission for a conservatory?

In most cases, you do not need planning permission to take down a conservatory. Demolition work is generally considered permitted development.

However, if the conservatory is part of a listed building or located in a conservation area, you might need to obtain permission.

Always verify with your local planning authority to ensure compliance with specific regulations.

What is a conservatory legally in the UK?

Legally, in the UK, a conservatory is defined as a single-storey extension with at least 50% of its side walls and 75% of its roof made of translucent materials such as glass or polycarbonate.

It must also be attached to the main dwelling and be thermally separated from the house by external-quality walls, doors, or windows.

This classification ensures it meets certain building standards and regulations.

Can you build your own conservatory in the UK?

Yes, you can build your own conservatory in the UK. Many DIY conservatory kits are available, making it possible for homeowners to undertake the project themselves.

However, it is essential to comply with building regulations and, if necessary, planning permissions. It is often advisable to consult with professionals to ensure the structure is safe and meets all legal requirements.

Is a conservatory cheaper than an extension in the UK?

Generally, a conservatory is cheaper than a traditional extension. This is due to the simpler construction methods and materials used, such as glass and uPVC.

However, costs can vary significantly depending on the size, design, and materials chosen. While conservatories are often more affordable, they might not offer the same level of insulation and versatility as a fully built extension.

What are the disadvantages of Planning Permission for a conservatory?

While conservatories offer numerous benefits, there are some disadvantages:

• Temperature Control: Conservatories can be too hot in the summer and too cold in the winter if not properly insulated.
• Maintenance: They require regular cleaning, especially the glass panels, to maintain their appearance.
• Security: Conservatories can be less secure than traditional extensions due to their glass structure.
• Limited Use: They might not be suitable for all purposes, such as bedrooms or offices, due to temperature fluctuations.

Can a conservatory be used as a bedroom in the UK?

Technically, a conservatory can be used as a bedroom, but it is not recommended. The primary issue is temperature control, as conservatories can get very hot or cold depending on the season.

Additionally, building regulations require that any bedroom meets specific standards for insulation, privacy, and safety, which a conservatory might not satisfy without significant modifications.

Does a conservatory need foundations?

Yes, a conservatory needs proper foundations to ensure stability and longevity. The type and depth of the foundations depend on the soil conditions and the size of the conservatory.

Typically, strip foundations or concrete pads are used, similar to those of traditional extensions. Proper foundations prevent issues such as subsidence and structural failure.

Can I build a toilet in a conservatory?

Building a toilet in a conservatory is possible, but it requires careful planning and adherence to building regulations. You must ensure adequate ventilation, plumbing, and insulation.

Additionally, the conservatory must be thermally separated from the main dwelling, which could complicate the project.

Consulting with a professional  is advisable to ensure compliance with all regulations.

Do I need an architect for Planning Permission for a conservatory?

Hiring an architect for a conservatory is not mandatory, but it can be beneficial. An architect can help design a conservatory that complements your home, maximises space, and meets all regulatory requirements.

Their expertise can ensure the project runs smoothly and meets your needs and aesthetic preferences.

What not to put in a conservatory?

Avoid placing items in a conservatory that can be damaged by extreme temperatures or sunlight, such as:

• Delicate Furniture: Fabrics and materials that can fade or deteriorate.
• Electronics: Devices that can overheat or malfunction in high temperatures.
• Books and Artwork: Items that can be damaged by humidity and sunlight.

It is best to use furniture and decor designed for conservatory conditions.

Can I build a conservatory without planning permission?

Yes, you can build a conservatory without planning permission if it falls within permitted development rights. This includes size and height restrictions and specific design criteria. Always check with your local planning authority to ensure your project meets all necessary requirements.

Do you need a door between the conservatory and the house?

Yes, building regulations typically require a door between the conservatory and the main house. This thermal separation helps with temperature control and energy efficiency. The door must be of external quality to provide adequate insulation and security.

Can I put a radiator in my Planning Permission for a conservatory?

Yes, you can put a radiator in your conservatory. However, it must comply with building regulations regarding energy efficiency and insulation.

Ensure the conservatory is adequately insulated to prevent heat loss, and consider installing a radiator designed for conservatory use to maintain a comfortable temperature.

What is the difference between Planning Permission for a conservatory and an extension?

A conservatory is primarily made of glass, with at least 50% of its side walls and 75% of its roof being transparent. It is designed to maximise natural light and provide a connection to the garden.

An extension, on the other hand, is a traditional brick-and-mortar structure that can be used for various purposes, offering better insulation and temperature control.

Extensions are often more versatile but also more expensive and complex to build.

Sunrooms and Serenity: The Final Note

Conservatories can be wonderful additions to your home, creating a light-filled haven and extending your living space. Understanding permitted development rights empowers you to determine if your conservatory vision can be achieved under this streamlined process.

However, don’t be discouraged if your plans extend beyond PD limitations. Planning permission, while requiring more steps, is still a viable option.

When Do I Apply for Planning Permission for a conservatory

Planning permission may be necessary if your house falls into any of the following categories: 

You are in designated areas (e.g., conservation areas, national parks, or listed buildings).

The conservatory is larger than the permitted size limits.

On any side of your house, you are extending beyond the current limits (for example, wrapping around a side and rear extension).

The materials and design are not in keeping with the appearance of your home.

You have considerably extended your home, thus exceeding the allowance for permitted development.

When in doubt, always check with your local planning authority (LPA) first.
