When deer are destroying your garden or woodland, fencing seems like the obvious solution. Build a barrier, keep them out, problem solved.

But deer fencing is expensive, often more than people expect. And it doesn’t always make sense. Here’s the honest truth about deer fencing: what it costs, when it works, and when there are better options.

How High Does Deer Fencing Need to Be?

Different species require different heights:

In Sussex, where fallow deer are the primary problem, you need minimum 1.8m fencing—and 2.0m is safer if dealing with large bucks.

A fence that’s too short is worse than useless. It costs money but doesn’t solve the problem.

Deer Fencing Costs

Materials Only

Posts are typically spaced every 3-4 metres, with straining posts at corners and every 100m on straight runs.

Installed Costs

Professional installation typically costs:

These figures include materials, posts, gates, and labour but exclude VAT.

Real-World Examples

Example 1: Large Garden (0.5 acre)

• Perimeter: ~180m
• Specification: 1.8m deer netting, wooden posts, one pedestrian gate
• Materials: ~£1,200
• Installation: ~£2,500
• Total: £3,500-4,500

Example 2: Small Woodland (2 acres)

• Perimeter: ~360m
• Specification: 2.0m deer netting, metal posts, two gates
• Materials: ~£3,500
• Installation: ~£4,500
• Total: £7,000-9,000

Example 3: Large Estate Planting (10 acres)

• Perimeter: ~800m
• Specification: 1.8m high-tensile, timber posts, multiple gates
• Materials: ~£8,000
• Installation: ~£10,000
• Total: £15,000-20,000+

Types of Deer Fencing

High-Tensile Wire Netting

The standard choice for most deer fencing:

Pros:

• Durable (15-25 year lifespan)
• Effective barrier
• Relatively unobtrusive from distance
• Proven technology

Cons:

• Significant upfront cost
• Professional installation recommended
• Gates are weak points
• Ongoing maintenance needed

Specifications to look for:

• Graduated mesh (smaller at bottom where deer push)
• Galvanised or galfan coating
• Minimum 2.5mm wire diameter for permanent fencing
• Tight to ground (critical for muntjac)

Electric Fencing

Can work for deer in some situations:

Pros:

• Lower capital cost than wire netting
• Flexible/moveable
• DIY installation possible

Cons:

• Requires power source
• Ongoing maintenance (checking, clearing vegetation)
• Less reliable—deer may push through
• Not suitable for all situations

When it works:

• Temporary protection (e.g., over winter)
• Adding to existing inadequate fence
• Training deer away from specific areas

When it doesn’t:

• High deer pressure with hungry animals
• Areas you can’t monitor regularly
• Permanent solution needed

Plastic Mesh Netting

Lightweight option sometimes used:

Pros:

• Cheap
• Easy to install
• Almost invisible

Cons:

• Less durable
• Deer can push through or tear it
• UV degradation over time
• Not suitable for high pressure

Best for:

• Temporary protection
• Low deer pressure areas
• Supplementing other methods

Solid Fencing

Close-board, panel, or wall fencing:

Pros:

• Complete visual barrier
• Deer can’t see what’s inside
• May deter more effectively

Cons:

• Very expensive (£50-100+ per metre installed)
• Planning permission often required
• Impractical for large areas
• Blocks light and wildlife movement

Generally only suitable for small, high-value areas where appearance matters.

When Fencing Makes Sense

Fencing is the right choice when:

Protecting High-Value Areas

• Commercial orchards
• Tree nurseries
• Show gardens
• Vegetable production

Where the value of what’s protected justifies the cost.

Enclosing Small Areas

A small kitchen garden within a larger property can be cost-effectively fenced while leaving the rest unfenced.

Creating Deer-Free Zones

Woodland regeneration plots, research areas, or conservation projects where complete exclusion is required.

Combined with Population Management

Fencing critical areas while managing deer numbers across the wider property—often the most effective overall strategy.

When Fencing Doesn’t Make Sense

Large Properties

A 50-acre estate would need ~1.8km of fencing. At £20/metre, that’s £36,000+ just to enclose the perimeter—and you’d still have deer inside.

Properties with Multiple Access Points

Every gate is a potential failure point. Properties with drives, footpaths, or multiple boundaries become impractical to fence completely.

When Deer Pressure is Extreme

In very high-density areas (like around Ashdown Forest), deer will test fences constantly. Any weakness gets exploited.

When You Don’t Address Root Cause

Fencing your garden doesn’t reduce the deer population. They simply concentrate damage elsewhere—your neighbour’s property, your unfenced woodland, or back to you when the fence eventually fails.

The Hidden Costs

Budget fencing calculations often miss:

Maintenance

• Annual inspection: £100-200
• Repairs (damage, fallen trees): £200-500/year average
• Gate hardware replacement: periodic
• Vegetation clearance along fence line: ongoing

Over 20 years, maintenance can equal original installation cost.

Gates

Every access point needs a deer-proof gate. Cheap gates fail first:

• Hinges sag
• Catches don’t secure properly
• Ground clearance allows deer underneath

Budget £300-500 per pedestrian gate, £600-1,000 per vehicle gate for something that will actually work long-term.

Terrain Challenges

Quoted prices assume reasonable ground. Add 30-50% for:

• Steep slopes
• Rocky ground
• Wet or boggy areas
• Dense vegetation requiring clearance

Boundary Issues

If you don’t own land right to the boundary, you may need neighbour agreements. Shared boundaries complicate everything.

The Alternative: Population Management

Instead of trying to keep deer out, reduce their numbers to sustainable levels.

Advantages over fencing:

*I provide free deer management for landowners who grant stalking access.

When population management is better:

• Large properties
• Multiple access points
• Moderate deer pressure
• When you want to reduce damage, not eliminate deer entirely
• As a complement to limited fencing

The Best Approach

For most landowners in deer-affected areas, the optimal strategy combines:

1. Population management as the foundation—reducing overall numbers and pressure
2. Targeted fencing for highest-value areas (vegetable garden, young orchard, regeneration plot)
3. Individual protection (tree guards) for specimen plants

This costs less than full fencing while being more effective across the whole property.

Getting Quotes

If you decide fencing is right for your situation:

1. Get multiple quotes (minimum 3)
2. Specify the same requirements to each contractor
3. Ask about guarantees and maintenance contracts
4. Check experience with deer-specific fencing
5. Request references from similar projects
6. Visit completed installations if possible

Be specific about species you’re excluding—muntjac-proof requires different detailing than fallow-proof.

My Recommendation

For landowners in Sussex experiencing deer damage:

Start with a free assessment of your situation. Understand deer numbers, movement patterns, and damage extent before committing to expensive infrastructure.

Often, population management alone reduces damage to acceptable levels. Where fencing is needed, it can be targeted to critical areas rather than entire boundaries.

I provide free deer management for landowners across East Sussex. No cost, no obligation assessment available.
