Why Choose Professional Security Fencing Installation Over DIY?

Many businesses and property owners may wonder if a DIY security fence installation is viable. While it might seem cost-effective, it often leads to compromised security, improper installation, damage to underground services and increased long-term costs.

However, if you choose professional installation you’ll get:

1. Compliance With The UK British  Standards

Professional fencing contractors ensure that your security fence installation meets all the UK quality and safety standards.

• Note: Planning permission is a dirty word for contractors – this is always the responsibility of the client, no matter the project! BS1722: The British Standard for fencing. All our installations meet British Standards for post dimensions, panel material and foundation strength.
• LPS1175 security ratings: If your site requires certified security fencing, we offer A1 (SR1) to D10 (SR4) LPS1175-rated fencing tested for resistance against break-ins.

2. Expertise In Choosing The Best Materials For Security Fencing

Professionals help you build a security fence by selecting the best type based on your property’s specific security needs:

• Weldmesh fencing – A cost-effective solution offering high visibility and anti-climb protection.
• Steel palisade fencing – Provides strong physical security and is ideal for uneven terrain.
• Acoustic fencing – Dual-purpose fencing that reduces noise while providing security.
• Steel railings – Combines aesthetic appeal with robust security, perfect for commercial spaces.

3. Secure And Professional Installation

• Safe digging techniques: Stiking electricic, gas or fibre optic cables is one of the greatest risks of fencing installation. Not only is it extremely costly, it is potentially deadly. Our installers are all trained on the use of cable avoidance tools, insulated digging tools and safe digging techniques.
• Proper foundation work: Incorrectly installed fence posts can compromise the entire structure. Professionals dig footings to relevant British Standards or engineers designs, then use the correct grade concrete to ensure stability.
• Anti-tamper fixings: DIY security fence installation often overlook security-rated fixings that prevent intruders from dismantling fence panels.
• Seamless integration with access control: Security fences often need gates, automation, or intrusion detection systems, which require expert setup and wiring.

4. Long-Term Cost Savings

A poorly installed security fence can lead to early deterioration, frequent repairs, or legal compliance issues. Hiring professionals ensures:

• Durable and high-quality materials for security fencing with warranties of 10–25 years.
• Lower maintenance costs.
• High-quality craftsmanship for a long-lasting security solution.

6 Steps To Build A Security Fence Professionally

Step 1: Assess Your Security Needs

Before choosing a fence, ask yourself:

• What are you protecting? (Property, assets, data centres, schools, etc.)
• What level of security do you need? (Basic deterrent or high-security certified fencing)
• Are there legal or planning permission requirements?
• Do you need additional features? (Anti-climb, privacy screening, automation, gates)

Now, according to your requirement, choosing the right type of security fencing, here are some security fencing solutions for different properties:

• Weldmesh fencing – A cost-effective, durable, and high-security mesh fence that provides excellent visibility and anti-climb protection.
• Steel palisade fencing – Strong, adaptable fencing ideal for uneven terrain. Its intimidating design is a strong visual deterrent.
• Steel railings – Aesthetic security fencing suitable for commercial properties requiring protection and visual appeal.
• Acoustic fencing – A dual-purpose fence that provides noise reduction and perimeter security, perfect for residential and commercial areas.

Step 2: Planning And Compliance

Security fencing must comply with the UK planning laws and safety regulations. You must know when you need planning permission?

YES, if your fence exceeds 1 metre (next to a highway) or 2 metres (elsewhere).

NO, if it is a replacement fence or within height restrictions.

• Security compliance: If installing fencing for a high-security site, you may require specific certifications like LPS1175.
• Local council approval: Always check local planning rules before installation.
• Secure by design: Schools and commercial properties should consult Secure by Design guidelines and select fencing heights and security ratings to suit.

Step 3: Preparing The Site

Proper site preparation is key to a strong, long-lasting fence.

• Survey the area – Identify boundary lines and clear any obstructions.
• Check for underground utilities – Avoid hitting gas, water, or electrical lines.
• Mark fence post locations – Space posts evenly (typically 2–3 metres apart, depending on fence type).

Step 4: Installing The Security Fence

 1️. Setting Fence Posts

• Dig post holes to correct British Standard or engineers details for stability.
• Use concrete foundations to secure posts, ensuring they are level and aligned.
• Allow concrete to cure for the correct amount of time before adding fence panels.

2️. Attaching Security Fence Panels

• Install weldmesh panels, steel palisades, or railings securely between posts.
• Use specialist anti-tamper fixings to prevent unauthorised removal.
• Consider adding privacy infills or anti-climb toppers for extra protection.

3️. Installing Security Gates And Automation

• If access control is required, install matching security gates.
• Automated gate systems improve convenience and security. These must be installed by DHF and GateSafe approved installers and meet Britsh Standard BS EN 12453: This standard specifies the safety and performance requirements for doors, gates, and barriers.

Step 5: Enhancing Security Features

For maximum protection, consider additional security enhancements:

• Anti-climb features – Razor wire, rotating spikes, or curved tops.
• Buried panels – Prevent tunnelling under the fence.
• Intrusion detection systems – Motion sensors and alarms.
• Security lighting and CCTV – Improve surveillance and deterrence.

Did you know businesses can claim capital allowances on security fencing, reducing tax liability?

Step 6: Regular Maintenance And Inspections

To keep your security fence in optimal condition:

• Inspect for damage, rust, or loose fixings.
• Repaint or recoat steel fences to prevent corrosion.
• Check gates, hinges, and locks for wear and tear.
• Schedule professional servicing every 12–24 months.
