Building Timber Post and Rail Fence can transform your property. It adds beauty and function, perfect for keeping livestock contained and marking boundaries. Incorporating electric fencing elevates security. This guide will take you through the steps of creating a timber post and rail fence and attaching electric fencing, ensuring you feel confident in the process.
Understanding Post and Rail Fencing
Post and rail fencing is a traditional approach featuring vertical posts and horizontal rails. This popular style is both rustic and versatile, making it ideal for farms, equestrian users and residential areas alike. Timber is commonly used for its durability and ability to blend with natural environments.
Key components of a post and rail fence include:
Posts: The vertical supports that hold everything together.
Rails: The horizontal bars connecting the posts.
Fasteners: Hardware needed to secure the rails to the posts.
With the right materials and tools, constructing a post and rail fence can be straightforward and rewarding.
Materials Needed
Before starting, gather these essential materials:
Timber posts (Round Posts typically 60mm, 75mm or 100mm round / also consider 75 x 125 posts)
Timber rails (88 x 38 square or 100mm half round rails)
Postmix (to secure posts)
Electric fencing wire
Insulators (to attach the electric wire)
Energisers and batteries
Nails or screws
A level
A saw
A post hole digger
A hammer or drill
Having all the materials on hand will streamline your building process.

Planning Your Fence Layout
Planning is crucial before you start digging. Consider these points:
Ideal Location: Make sure the area is clear of trees, rocks, or utility lines. A clear zone prevents future maintenance issues.
Accurate Dimensions: Measure the total area for the fence. Use stakes to mark corners and where any gates will be placed. You can use our online tools to help calculate the number of posts required https://www.foxhillstimber.co.uk/calculator
Post Spacing: Ideally, space posts 6 to 8 feet apart to ensure stability.
With a clear plan, you are set to move forward.
Digging Post Holes
Using a post hole digger, dig holes for your posts. Each hole should reach one-third the height of the posts. If your posts are 6 feet tall, dig at least 2 feet deep. Aim for a width that accommodates the post and concrete.
Setting the Posts
Once your holes are dug, setting the posts is next. Position each post in its hole and use a level to ensure they stand straight.
To secure the posts:
Using Postmix is the quickest way as you can pour water into the hole and then add Postmix a bit at a time adding more water if needed until the hole is full. Be sure to mix the water and Postmix periodically to get best results.
If using round posts with a 2 or 4 way point you can generally drive the post in without digging using a post whacker.
Most postmixs start to set within 10 - 15 minutes, but be sure to follow any instructions on the packaging
Attaching the Rails
Once the posts are set, you can attach the rails:
Measure and Cut: Measure the distances between the posts and cut the rails to fit accurately. Ideally if spacing the posts every 1.80m or 6 foot you can span a 3.66m rail across two bays.
Decide on Rail Count: Installing two or three rails is often sufficient for most applications. The more rails, the sturdier the fence will be.
Secure the Rails: Use nails or screws to fasten the rails to the posts, ensuring they are level and evenly spaced.
Installing Electric Fencing
Now that your fence structure is solid, it's time to add electric fencing for enhanced security. Here’s how:
Choosing the Right Electric Fencing System
We supply a full range of electric fencing from Agrifence which covers all the components required below.
Installing Insulators
Attach insulators to the posts/rails at a height suitable for the animals you’re containing. For example, larger animals like cattle may require a higher setup, while smaller livestock like goats can be lower.
Running the Electric Wire
Run the electric wire through the insulators. Ensure the wire is taut but not overly tight to allow for some tension.
Connecting the Energizer
Follow the manufacturer’s instructions to connect the electric wire to an energizer. Prioritize safety protocols to avoid accidents.
Testing the Fence
It’s essential to verify your electric fence is working correctly. Use a voltage tester to ensure the wire maintains appropriate voltage. A properly functioning electric fence will keep livestock safe and deter potential intruders.

Maintenance Tips
Maintaining your fence keeps it secure and extends its life. Here are some easy maintenance practices to follow:
Regular Inspections: Look for loose rails or damaged posts regularly. Repair any issues promptly to maintain integrity.
Clean Around the Fence: Clear debris and overgrown vegetation, which can cause damage over time. Trimming back plants within a few feet of the fence can help prevent unwanted wear.
Monitor the Electric Fence: Test the electric fencing system at least once a month to guarantee it’s operating efficiently.
Wrapping Up
Building a timber post and rail fence with electric fencing attachments is both practical and rewarding. By gathering the right materials, preparing a solid plan, and committing to maintenance, you can create an attractive and secure fence.
Enjoy enhancing your property while ensuring your livestock is safe and secure. Happy fencing!
