The garden fence, a defining feature of many UK homes, serves various purposes from providing privacy to enhancing security. However, when it comes to erecting or altering a garden fence, homeowners must adhere to specific regulations regarding its height. In this article, we’ll explore the guidelines surrounding garden fence height in the UK to help you make informed decisions and stay compliant with local regulations.

How High Can a Fence Be in the UK?

Legal Framework

The regulations governing garden fence height in the UK are primarily determined by local planning authorities and are typically outlined in the Town and Country Planning Act 1990. It’s crucial to check with your local council to understand the specific rules and guidelines applicable to your area, as there may be variations between different regions.

Front Garden Fences

In the front garden, where visibility is a key concern for road safety, regulations often impose height restrictions on fences. Commonly, fences in the front garden are limited to a maximum height of 1 meter (3.28 feet). This measurement includes any posts or trellis added to the fence. Some areas may permit slightly taller fences, but it’s essential to check with your local council for precise details.

Rear and Side Garden Fences

In rear and side gardens, where privacy is a higher priority, homeowners usually have more flexibility regarding fence height. While there may be permitted heights, often ranging from 1.8 to 2 meters (approximately 5.91 to 6.56 feet), it’s crucial to confirm these specifics with your local council. If you plan to install a taller fence, especially in conservation areas or for listed properties, you may need to seek planning permission.

Additional Considerations:

  1. Trellis and Additional Features: If you decide to add trellis or lattice to the top of your fence for decorative purposes, it’s vital to include this in your overall fence height measurement. Typically, these extensions are allowed up to 30 centimeters (approximately 11.81 inches) on top of the fence height.

  2. Listed Properties and Conservation Areas: If your property is listed or situated in a conservation area, stricter regulations may apply. In such cases, it’s advisable to consult with your local council and seek planning permission for any alterations to your garden fence.

  3. Boundary Disputes: Before making any adjustments to your fence height, it’s crucial to communicate with neighbors and ensure you are clear about property boundaries. Disputes over fence heights and locations can be avoided through open and respectful communication.

Determining Ownership and Understanding Fence Regulations

Determining ownership and adhering to fence regulations are crucial aspects of maintaining a harmonious relationship with your neighbors. Before making any alterations or additions to a fence, or considering the installation of a new one, it is essential to confirm the property boundary.

Verifying Ownership:

To ascertain ownership, refer to the property deeds, where details about the boundary and ownership of the fence are highlighted. While traditionally the fence to the left of your garden is often owned by your neighbor, this may not always be the case.

Communication is Key:

To avoid potential conflicts, it is highly recommended to engage in open communication with your neighbor before making any modifications to a fence. Discussing your plans can prevent disputes and foster a cooperative approach to shared property lines.

Consider Your Neighbors’ Needs:

When altering a fence, be mindful of your neighbors’ concerns, which may include:

  • Existing attachments such as plants, birdhouses, or garden art on the fence
  • Pets that require containment, such as dogs, cats, or rabbits
  • Security considerations
  • Potential impact on light levels due to increased fence height

Initiating a friendly conversation and attempting to accommodate their needs, such as providing advance notice, can contribute to a positive resolution. In cases where ownership is unclear, a fair solution could involve sharing the costs of fence alterations.

Height Regulations:

Understanding fence height regulations is vital to prevent legal issues and maintain neighborhood harmony. Some key considerations include:

  • The height limit for back garden fences in the UK is typically 2 meters.
  • Front garden fences or those adjoining highways are often limited to 1 meter.
  • Conservation areas may have specific rules.
  • Pleached trees can be used to gain height beyond 2 meters, but it’s crucial to consult local authorities and consider the impact on neighbors.

Wind Considerations:

Opting for the maximum fence height limit may expose your fence to stronger winds, leading to potential damage. To reinforce fence panels, select appropriate-sized fence posts, such as 8ft for 6ft high panels, and ensure they are securely anchored with concrete. Concrete posts are preferable due to their durability.

Hedge Height and Considerations:

Unlike fence panels, specific height limits for hedges do not exist. However, the law stipulates that hedges should not adversely affect neighbors, such as blocking sunlight. If you plan to raise a back garden fence above 2 meters, pleached trees can offer added height without planning permission.

Quick Reference for Fence Height Limits:

  • Back garden fence: Usual maximum height is 2 meters.
  • Front garden or fence adjoining highways: Maximum height is 1 meter.
  • Conservation areas may have specific rules.


Understanding the regulations surrounding garden fence height in the UK is essential for homeowners looking to make improvements to their outdoor spaces. By checking with your local council, considering the specific requirements for front, rear, and side gardens, and adhering to additional considerations, you can ensure that your garden fence complies with legal standards while meeting your aesthetic and practical needs. Always consult with local authorities to get accurate and up-to-date information tailored to your specific location.
