Most people are aware of the regulations regarding planning permission for extensions, but do they apply for a conservatory?
Well, yes and no. In this blog, we’ll explain when and why you may need planning permission to build your new conservatory.
Can I buy a Conservatory Without Planning Permission?
If you are planning a significant building development project, such as a conservatory, you should first think about planning permission.
Buying a conservatory is not cheap, so you need to make sure you are within your rights to erect a new structure or build on your existing property.
In most cases, conservatories, like extensions fall under permitted development rights, however, there are exceptions.
Permitted Development Rights
Permitted development rights allow you to build a conservatory if:
- It is a single-storey extension with a maximum height of 3m or 4m high (if within a 2m boundary)
- It does not cover more than 50% of the garden
- The roof ridge or top point is not higher than the original roof of the house
- It does not extend beyond the sidewall of the house
- It does not include raised platforms, balconies or verandas
- It is less than 50% in size of the total area around the original property
A detached property can now extend 8 metres, while a semi-detached or terrace house can extend a maximum of 6 metres.
Other reasons you may need to seek planning permission include:
- You wish to use different materials than those used on the exterior of your main property
- You live in a conservation area or other designated area
- You live in a listed building – listed buildings have specific consent requirements
Neighbour Consultation Scheme
In May 2019, the UK Government relaxed the permitted development rights regarding conservatories, making it easier for homeowners to extend their properties with a conservatory.
Until then, non-detached properties were only eligible for a 3m single-storey extension, while detached properties could add a single-storey extension, a maximum of 4m. The change was to enable families to grow without having to move.
Instead, they decreed that the conservatory must have no negative impact on your neighbour’s property.
Neighbours can object to extensions, including conservatories, under the ‘Neighbour Consultation Scheme’.
So, while you may not need planning permission for your conservatory, you should always consult your neighbours before undertaking any work. as it will affect them too.
Your local authority will consult your neighbours when you inform them of your intention to build, but it is best if it comes from you.
Even if the conservatory won’t negatively affect your neighbours, the building work may disrupt their lives, so you should try to work with them to find a convenient time for the installation.
Lastly, any new build or add-on must adhere to Building Regulations.
The Importance of Planning Permission
If you choose to go ahead without obtaining planning permission or checking if it is required, the local authority has the right to demolish or alter the project. You will also have to make a retrospective planning application at your own expense and can incur higher costs if you lose your appeal.
While altering most properties without planning permission isn’t illegal, doing so to a listed building is a criminal offence. If found guilty, you can be fined an unlimited amount and, in extreme cases, even face imprisonment.
How to apply for planning permission
The process for most homeowners has been streamlined considerably. If you are planning a conservatory, you can now alert your local authority, who will consult with your neighbours and decide if any objections are valid. If the local authority feels your plans are likely harmful to your neighbours or the area, they can reject them or ask for modifications.
If you require planning permission, there is both a cost and waiting time, so always factor both in when planning any significant home improvements.
The Planning Application Process:
Planning permission applications are granted following a combination of local authority planning policies and national guidance from the National Planning Policy Framework.
To gain planning permission, you must submit accurate survey drawings and technical information provided by experts.
All local planning authorities use the same form, the 1APP, which you can download and submit your application online via the Planning Portal.
It can be a lengthy process, even online, requiring the following:
- Five copies of application forms
- Signed ownership certificate
- Location plan, block plan, and elevations of both the existing and proposed sites
- Design and Access Statement
- Drainage information
- The complete payment
Other documents you may need to supply include:
- An ecological survey
- Tree survey showing root protection zone
Types of Planning Permission
There are three types of planning permission – Outline planning permission, Full Planning Permission, and Householder Planning Permission.
Outline Planning Permission
Here, a ‘permission in principle’ is offered, stating that the proposed project is viable. However, this does not allow you to begin work. You will then need to apply ‘reserved matters’ detailing the design, materials to be used etc.
Full Planning Permission
Obtaining full planning permission means the local authority has granted consent for a detailed design. You must meet stipulated planning conditions and acquire a letter from the local authority to this effect before the project can get underway.
Householder Planning Permission
This grants homeowners permission to extend or otherwise alter a house within the boundary of the property.
The Cost of Planning Permission
The average cost of planning permission for a conservatory is around £2,000- £3,000, depending on the scope and complexity of the job and your location.
If you are granted outline planning permission, all materials and details must be approved, costing £100+ for each application. One application can include multiple details and materials.
How Long Does Planning Permission Usually Take?
The average time for a planning permission application to be approved or rejected is around eight weeks. However, this can increase to around 13 weeks for particularly complicated or large designs.
How Long Does Planning Permission Last?
You will be notified at the time how long your planning permission is valid. It is usually around three years from the date permission is granted. If you need longer, you can reapply. Bear in mind that legislation may change, so you are not guaranteed to be approved the second time.
Is it Illegal to Have a Radiator in a Conservatory?
Some people think having a radiator in their proposed conservatory design could affect planning permission but that is not the case.
There are reasons for and against having a wall-mounted or freestanding radiator in your conservatory, but it is certainly not illegal and will not affect planning permission.
Alternative Solutions:
MyJobQuote has reported that, in England, around 86% of applications are granted, with approximately 40% of those rejected granted planning permission at appeal.
If planning permission is not granted, try to alter your plan so it addresses the concerns laid out in the refusal statement. For example, it could be the materials you plan to use that do not match the area – rethink your design to be more in tune with the local architecture. You can consult a local architect or planning consultant to help you.
You get a free resubmission if your initial application is refused and it does not affect your credit or standing as a homeowner.
Conclusion:
To recap, most conservatories can be installed without planning permission, but you should always check with the local authority and your neighbours before any work begins.
