Needing a special safety sign? Why not create your own?
Driving through the British countryside, you will see everything from hand-painted boards for fresh eggs to towering hoardings announcing a new housing development on former grazing land. For a farm owner or a site manager, the question of whether you can simply bolt a sign to a gate or plant a post in a verge is rarely straightforward. There is a common assumption that because agricultural land often falls under permitted development, the rules for signage are equally relaxed. In reality, the intersection of the Town and Country Planning (Control of Advertisements) (England) Regulations 2007 and local authority oversight creates a complex landscape where a simple mistake can lead to an enforcement notice.
Navigating agricultural sign planning permission requires a clear understanding of the distinction between safety requirements and commercial advertising. While the Health and Safety Executive (HSE) might demand that you display specific warnings, the local planning department may have different views on the visual impact of those same boards. Getting this balance right is essential for maintaining a compliant, professional operation without falling foul of the law.
Most farmers and rural contractors operate under what is known as Deemed Consent. This means that for certain types of signs, you do not need to submit a formal application to the local planning authority. These are usually small, functional signs that serve a specific purpose rather than promoting a large-scale commercial venture. For example, signs that are necessary for the safe operation of the farm or to guide visitors typically fall into this category, provided they stay within specific size limits. Exploring our signs can give you a better idea of the standard sizes and styles available for these purposes.
Typically, a sign does not require formal permission if it is related to the land on which it is displayed. If you are selling produce grown on that specific farm, or if the sign is purely for identification, you are generally on safe ground. However, the moment that sign becomes illuminated, or if it exceeds a certain height from the ground (usually 4 metres), the rules change significantly. Understanding these boundaries helps prevent the frustration of having to remove expensive signage after it has already been installed.
Common scenarios where Deemed Consent usually applies include:
Identification signs showing the name of the farm or agricultural holding.
Temporary signs for local events like seasonal farm shops or “open farm” days.
Directional signs for public footpaths or bridleways crossing the property.
Statutory safety signs required by law to protect employees and the public.
For those managing public access, public footpaths across your land the signs that protect you from liability are often considered essential for land management and rarely face planning resistance. The key is ensuring the sign is proportional to the need and does not create a distraction for road users.
One of the most frequent points of confusion for site managers involves Farm & Agricultural Signs that are mandatory for safety. Under the Health and Safety (Safety Signs and Signals) Regulations 1996, employers must provide specific signage where a risk cannot be avoided by other means. Because these are legal requirements, planning authorities are almost always supportive of their installation. It is very rare for a council to block a sign that is clearly intended to prevent a serious injury. To ensure your property is fully compliant, you should browse our dedicated range of farm agricultural signs designed specifically for rural environments.
However, even Hazard Warning Signs must be placed thoughtfully. If you are installing a large multi-hazard board at a site entrance, it should be positioned so it is visible to those entering but does not obstruct the sightlines of drivers on the public highway. Planning rules for farm gates often focus on highway safety, so ensure your signage does not overhang the road or interfere with traffic signals. If you are unsure which specific warnings are mandatory for your site, our guide on which safety signs does a UK farm actually need by law provides a practical breakdown of your obligations.
Strictly speaking, safety signs are not “exempt” in the way many people think, but they are generally viewed as “functional advertisements.” This means they are permitted as long as they are no larger than is reasonably necessary to convey the safety message. If you are using 12 essential farm warning signs every working farm should display, keeping them to a standard size like A3 or A2 usually ensures you stay within the Deemed Consent limits.
If you are managing a rural construction project, you may also need to consider workplace safety signs that address specific machinery or chemical hazards. While these are vital for compliance, they should be mounted on existing structures where possible to avoid the need for new, permanent posts that might trigger a planning review in sensitive rural areas like AONBs (Areas of Outstanding Natural Beauty).
While many signs are allowed, there are clear “red lines” that will almost always require a formal planning application. Planning permission for rural signs is often restricted based on the visual impact on the landscape. Local authorities in the UK are particularly protective of the “open character” of the countryside, and they have the power to restrict even small signs if they believe the area is becoming cluttered.
You will almost certainly need to apply for Express Consent if your signage plans involve any of the following:
Illuminated signs, such as backlit boards or spotlights, which are generally discouraged in rural areas due to light pollution.
Signs exceeding 0.3 square metres in an Area of Outstanding Natural Beauty or a National Park.
Hoardings or large billboards that promote products not grown or produced on the farm.
Permanent signs located away from the farm itself, such as on a nearby main road verge.
Any sign that is higher than 4.6 metres above the ground.

The material and design of your signage can actually influence how it is perceived by planning officers. A flimsy, hand-written board might be seen as an eyesore, whereas a professionally manufactured sign from our range of General Safety Signs demonstrates a commitment to professional standards and safety. Using durable materials like aluminium composite or rigid plastic ensures the sign remains legible and does not become a piece of litter after one winter, which is a common complaint in rural planning enforcement.
