Garden Fence Panels for Security and Anti Intrusion

When people think about home security, they often focus on alarms, cameras and locks. But your fence is your first line of defence. The right setup can deter opportunistic intruders before they even step foot on your property.

In this guide, we’ll break down the most common ways intruders bypass fence panels and, more importantly, how to stop them.

Why fence panels matter for security

A weak or poorly installed fence makes access easy. A strong, well thought out fence does the opposite. It:

  • Creates a clear boundary
  • Reduces visibility into your garden
  • Slows down or discourages entry
  • Signals that your property is protected

Most intruders are looking for the easiest target, not the toughest one.

Common intrusion methods and how to stop them

Understanding how people actually bypass fence panels is key to improving your security.

1. Lifting fence panels out of their posts

The problem

Many fence panels are simply slotted into posts, especially when using concrete posts with grooves. While this makes installation easier, it also creates a weakness.

This is the most common way a burglar or intruder will access a garden or property via fencing.  They lift the panels within the slot, sometimes place an object underneath to keep the panel raised, and then gain access to the garden or the property. The entire process is silent, and it is also easy to pass items through the opening, whether these are possessions, pets, or anything else.

An intruder can:

  • Lift the panel straight up
  • Tilt and pull it free
  • Gain access quickly and quietly

This is one of the most common and overlooked vulnerabilities in garden fencing.

Thief Lifting a Fence Panel

The solutions

Fix panels with screws directly to the posts for maximum security

  • Use wooden slotted posts, as these are ideal for screwing through into the panel
  • Choose posts with long guarantees to reduce the risk of rot over time
  • Use stainless steel screws to prevent rust and maintain strength
  • Fix from the inside of the fence, so screws cannot be accessed externally
  • Torx head screws are recommended as they are harder to remove than standard screw types

Read our blog on the importance of attaching fence panels to fence posts

Consider fully fixed fencing

Feather edge style fencing in traditional or kit-form is built in place rather than slotted in, meaning it cannot simply be lifted out. It is an option but decorative panels are not available in kit form and fixing using the above methods are better.


Secure the panels with brackets or clips

This is not the best solution and often used with concrete posts.  It can look unattractive and panels can still be lifted usually lifting the panel next to the panel being lifted at the same time.

Even though they are not the best, they are: 

  • Cost effective
  • Easy to install
  • Acts as a visible deterrent


Use recessed or tight fitting systems or wedges

Panels that sit deeply within slotted posts are harder to remove, especially if combined with fixing or very tight wedges.


2. Climbing fence panels

The problem

If someone can climb over your fence, they do not need to force their way through it. This remains one of the most common methods of entry, but unlike lifting panels, where the opening itself becomes the route in and out, climbing is usually used only to reach the garden or the property. Once inside, a gate is often opened from the inside, or possessions are passed or thrown over the fence.

Common climbing aids include:

  • Horizontal rails or slats
  • Nearby bins or garden furniture
  • Low fence height

The solutions

Increase fence height

Standard fences are usually around 6ft. Adding extra height can make a significant difference in preventing access.  Read our blog on What height fence is considered secure

Choose anti climb designs

Avoid fence styles that provide easy footholds. The way a panel is constructed has a huge impact on how easy it is to climb. Good anti climb fence panel styles include:

  • Vertical board fencing (closeboard, tongue and groove) – smooth upright boards with very limited footholds
  • Fence panels without rails like Chilham Panels
  • Panels that are harden to climb with rails running vertically

Styles to be cautious of:

  • Hit and miss fencing (horizontal) – creates a step pattern like a ladder
  • Slatted panels with wide gaps – can provide footholds depending on spacing
  • Panels with exposed horizontal rails – offer easy step up points

The key principle is simple: the fewer horizontal elements on the outside of the fence, the harder it is to climb.

Add a difficult to climb fence topper

  • Angled fence toppers like Jacksons Viking topper Panel
  • Rounded or curved finishes
  • Roller style anti climb bars

Use trellis toppers

  • Opt for thin, flexible designs that won’t support weight
  • Avoid rigid square trellis that acts like a ladder
  • Position it inward where possible


Consider fence spikes (with caution)

  • Unsightly
  • Dangerous in residential settings
  • Glass broken used to be traditionally used
  • Requires warning signs

Remove climbing aids

  • Move bins and storage away from boundaries
  • Avoid placing furniture close to fencing
  • Cut back trees and large shrubs

3. Breaking through the panel

The problem

If a fence panel is weak, damaged or poorly made, it can simply be broken through rather than climbed over or removed.

An intruder may:

  • Kick through thin or rotting boards
  • Break overlapping slats apart
  • Force gaps open in low quality panels

Overlap panels in particular can be vulnerable, especially if they have weathered over time or were cheaply made.

The solutions

Choose stronger panel construction

  • Panels that are framed and use thick boards 
  • Panels with interlocking boards
  • Thick, well fixed vertical boards
  • Look at panels that use good fixings.  Some use small stainless steel screws throughout.

Maintain your fencing

  • Replace damaged or loose boards
  • Treat timber regularly to prevent rot or if buying new then look for long guarantees like 25 years
  • Check for soft spots or movement

Reinforce weak areas

  • Add additional vertical battens
  • Reinforce the rear with rails
  • Secure loose boards with screws

Avoid ageing or low quality panels

Older panels that have absorbed moisture or started to rot are much easier to break. Replacing them before they fail is key to maintaining security.

4. Not Panels but Keeping Garden Gates Secure

The problem

Even with secure fencing, a weak or unlocked garden gate can provide easy access.

An intruder may:

  • Just open the gate an walk through
  • Lift it off its hinges
  • Climb over and unlock the gate


The solutions

Install secure locks
  • Use a key operated lock or heavy duty bolt
  • Avoid simple lift latches for external access points
  • Use Breton bolts and add pad locks

Use security hinges or invert the top hinge

  • Prevents the gate being lifted off its hinges
  • Adds an extra layer of protection if hinges are tampered with

Ensure a tight fit

  • Reduce gaps between the gate and posts.  10mm is the standard gap between posts and the gate.
  • Make it harder to reach through and unlock from the outside

Choose a strong gate design

  • Match the strength of your fence panels
  • Avoid lightweight or decorative gates in vulnerable areas

Position locks on the inside

Where possible, ensure locks and bolts are only accessible from inside the garden.



Garden Fence Panels Tactics for Security

Fence security is not just about strength. It is about removing weaknesses and reducing opportunity.

  • Stop panels being lifted with brackets or fixings
  • Make climbing harder with height and design
  • Use strong, well maintained panels to prevent break ins

A well secured fence will not just protect your garden. It will also make your home a far less appealing target in the first place.

If you want to go further, combining strong fencing with lighting and cameras will give you even better overall security.  Again, Jacksons build the strongest garden fence panels on the market or read our blog on the best garden fences for security
