Why Choose Timber Post and Rail Fencing?
A timber post and rail fence is one of the most versatile and cost-effective fencing solutions for UK gardens, paddocks, and rural property boundaries. Its open-frame design provides a clear boundary without obstructing views, making it a favorite for:
Durability: When using pressure-treated (UC3 or UC4) timber, these fences can withstand the British elements for decades.
Livestock Safety: The traditional choice for equine and agricultural use.
Ease of Repair: If a single rail is damaged, it can be replaced without dismantling the entire fence line.
- Aesthetics: Offers a classic "countryside" look that adds value to any property.
Pre-Installation: Planning & Calculations
Before you pick up a spade, precision planning is essential to ensure a sturdy result.
Check for Underground Services: Always use a cable avoidance tool (CAT) to check for water pipes or electrical lines before digging.
Calculate Your Bays: Use our handy post and rail fencing calculator to work out how many rails and posts you will need.
Check Boundaries: Ensure your fence is situated entirely within your property line to avoid future disputes.
Step-by-Step Guide
Step 1
Before you start, double-check that you have all the necessary tools and equipment for the job.
- Saw
- Level
- Tape Measure
- Screwdriver or Power Drill
- Hammer
- String
- Safety Gear
- Timber post and rail products
- Post Mix
Gather all these items together so you have everything in place, ready for you to start the installation.
Step 2
Look at the ground, is it a suitable area to install the timber post and rail fencing?
If so, plan out the layout of your post and rail fence using your string to make sure your fence line is exactly where it needs to be.
Sometimes it might be tempting to just get started, but these earlier preparation steps can help avoid any errors in future steps.
Step 3
Dig the foundation holes 600mm deep by 350x450mm wide for each post.
Ensure the holes are spaced correctly for your posts and set using the post mix.
Step 4
Once the posts are securely in place, attach the rails to the posts with nails.
Make sure that you use 2 nails per post end.
Step 5
Inspect your timber post and rail fencing, and make sure that everything is in the correct place and position before it completely sets, and you cannot change it.
You can also look to add treatment if you wish once everything is in position.
Step 6
Ensuring that you make time to regularly inspect your timber post and rail fencing is very important; this will help minimise any damage and deal with any imperfections as soon as possible.
Practical Tips for a Stronger Fence
Space posts evenly to avoid sagging rails.
For paddocks, consider three or four rails for strength and livestock safety.
Use galvanised nails or screws to prevent rust.
Always wear safety gear when using tools and working with timber.
Frequently Asked Questions (FAQ)
- How deep should post and rail fence posts be?
- For most domestic and agricultural applications, posts should be buried at least 600mm (2 feet) deep. For corner posts or gate posts which take more tension, we recommend a depth of 900mm.
- Do I need planning permission for post and rail fencing?
- In the UK, you generally do not need planning permission for a fence under 2 meters in height. However, if the fence is adjacent to a highway, the limit is often 1 meter. Always check with your local authority if you are unsure.
- How do I install post and rail fencing on a slope?
When working on a gradient, you should "step" the fence. Keep the posts vertical but allow the rails to follow the natural contour of the land, or step the rails down in increments to maintain a level top line.
