School security fencing
Security fencing on a school is there to delay and deter: to stop casual trespass, to make a determined intruder slow and obvious, and to keep pupils in during the day. It does that best when it is hard to climb, hard to cut and easy to see through.
This page covers the fence types schools use for a secure boundary, the heights that are normal, what a security rating does and does not tell you, and what a scheme costs per metre.
£90 to £160 a metre
358 anti-climb mesh, 2.4 m to 3.0 m, fitted, before VAT.
When a school needs security fencing
- Trespass, vandalism or arson out of hours, or adults crossing the site in the day.
- A safeguarding review or audit has found pupils can leave, or strangers can reach a playground.
- The old boundary is chain link, timber or low railings that have failed or can be stepped over.
- A new building, entrance or car park has changed where people come and go.
- A council guidance note expects a boundary of generally 1.8 m or higher; yours is lower.

Where these figures come from
Per-metre and gate figures are installed prices from published UK contractor price guides, autumn 2026 (read 2 November 2026). The guides do not say whether VAT is included, so treat them as before VAT and check. Most state schools and academies can recover VAT; ask your finance team. Contract awards for whole schemes are listed on the home page. A guide, not a quote.
What makes a school fence secure
Height is only one part. These are the details that separate a fence that deters from one that just marks the line.
Aperture
Standard weldmesh has 200 mm by 50 mm openings; 358 mesh has openings about 76 mm by 13 mm, too small for a fingertip or a shoe, and too tight for bolt cutters to grip easily.
No ladders
No horizontal rails on the outside face, and nothing within reach to climb: bins, walls, benches or low branches.
Height
2.4 m is the common choice for a school perimeter; 3.0 m where the boundary meets a footpath or has a history of intrusion.
Ground line
Panels set close to the ground and stepped on slopes so there is no gap to crawl under. A buried or concreted base rail on soft ground.
Fixings
Security clamp bars and tamper-resistant bolts fixed from the inside, so the panels cannot be unbolted from the street.
Finish
Hot-dip galvanised and polyester powder coated; dark green is the usual school colour and the least visually intrusive.
Security ratings: LPS 1175 in plain terms
Some fences and gates are tested and certified to LPS 1175, the Loss Prevention Certification Board standard for intruder resistance. Issue 8 rates a product on two separate scales: a letter from A to H for the tools and number of attackers assumed, and a number (1, 3, 5, 10, 15 or 20) for the minutes of delay it should give against manual forced entry. Older products carry the Issue 7 grades SR1 to SR8.
Most school perimeters do not need a rated fence. A rating earns its cost on stretches that protect something specific: a plant room, a server or kitchen store, a boundary with repeated break-ins. Certified products are listed in the LPCB Red Book; ask the contractor for the listing, not just a brochure claim. Our note on LPS 1175 covers the grades.
DfE’s guidance does not name a fence type or rating. It asks the school to assess its own risks and lists effective perimeter fencing alongside access control, CCTV, lighting and alarms (DfE, potential security threats and preventative measures).

Request quotesHow a security fencing scheme gets done
Walk the boundary
Measure every run, note heights, gates, levels, trees, drainage and who owns each stretch. Walk it from outside too.
Write one specification
Fence type and height per run, finish and colour, gate hardware, and whether planning consent is needed. Quotes only compare if they price the same thing.
Quotes or call-off
Three quotes under your finance rules, or a call-off from a construction framework your council or trust already uses.
Install, secure every night
Phased so no stretch is left open overnight, with noisy work and gate changes timed for a holiday where possible.
Questions schools ask
What is the best security fencing for schools?
For most perimeters, 2.4 m welded mesh in dark green, upgraded to 358 anti-climb mesh on footpath and rear boundaries. Palisade suits service yards. Railings suit the road frontage where the school wants an open, welcoming look.
How high should school security fencing be?
Council guidance cites an expected boundary of generally 1.8 m or higher (Buckinghamshire Council); 2.4 m is the common new-build height and 3.0 m is used on high-risk stretches. Planning consent is usually needed above 1 m next to a road and above 2 m elsewhere.
Is 358 mesh too much for a primary school?
Not on every run, but it is often the right answer on the one or two stretches where trespass actually happens. Many schools mix 2.4 m weldmesh on the visible boundaries with 358 mesh where the site backs onto a path or open land.
Does anti-climb fencing need warning signs?
Plain mesh does not. If a topping that can injure is added, such as razor wire or spikes, the occupier owes a duty to people who may be hurt, including trespassers, so warning signs and a careful risk assessment are needed. Most schools avoid injurious toppings altogether.
How long does school security fencing last?
Galvanised and powder-coated steel mesh commonly lasts 25 years or more with little maintenance beyond checking fixings, gates and damage after each term.
Can we fence only part of the boundary?
Yes, and a phased scheme is common. Start with the stretches your site walk and incident log show are the weakest, and specify the same system so later phases join cleanly.
