Fencing Cost Calculator
Estimates the cost of garden fencing in the United Kingdom. Four types: wire mesh, removable panels, timber and precast concrete. Materials and labour.
For a detached home on a plot of 10 m × 8 m in the South East, the total perimeter to fence is 36 m. In galvanised hexagonal mesh netting with 1.2 m height, those 36 linear metres require posts every 2.5 m — that is, 16 posts. The total cost results from the length multiplied by the price per linear metre of fencing, plus the posts, plus the labour for installation. This calculator estimates the cost based on the length to fence, the type of fencing and the prices of materials and installation.
Fencing defines the boundary of a property, changes the exterior appearance of a house and provides privacy. In the United Kingdom, the cost per linear metre varies considerably depending on the type chosen, between galvanised wire mesh, the most affordable solution, and precast concrete fencing, the most durable. Anyone requesting quotations without knowing reference prices is at an immediate disadvantage in negotiation. The choice of fencing type is not only aesthetic; it reflects durability, maintenance and installation cost over decades.

Garden fencing: how to calculate cost in the United Kingdom
Fencing marks the boundary of a property and offers privacy, security, and aesthetic definition to an outdoor space. Across the UK, the cost per linear metre varies markedly according to type chosen. From affordable galvanised wire mesh to durable precast concrete, each option presents different trade-offs between initial investment, lifespan, and maintenance burden.
The calculation is straightforward: multiply the total perimeter length to be fenced by the material price per linear metre, then add labour cost. This calculator performs exactly that calculation using price information from the UK market across the four most common fencing types.
Fencing types and cost scale in the United Kingdom
| Fencing type | Material cost (relative) | Installed cost (relative) | Maintenance |
|---|---|---|---|
| Galvanised wire mesh (1 m height) | Very low | Low | Virtually none |
| Timber fencing (1 m height) | Low to medium | Medium | Periodic treatment with exterior stain or preservative |
| Steel mesh or palisade panels (1.5 m height) | Medium to high | High | Inspection and repainting as needed |
| Precast concrete panels (1 m height) | High | High | None for 40+ years |
The relative scale reflects information from builders' merchants and quotations from local installers. In areas with difficult access (city centres, steep slopes, narrow passages) labour rates may be notably higher. In suburban and rural areas, they typically sit at lower ranges. Enter the prices from your actual quotation in the calculator for a personalised estimate.
The four most common fencing types in the UK
Galvanised wire mesh is the most economical solution and most used around rural properties, market gardens, and rear boundaries. Steel mesh rolls, either welded or hexagonal in hot-dip galvanised finish with 1 m height, are the lowest-cost option per linear metre on the UK market. Installation requires rectangular hollow section posts (typically 75 × 75 mm), spaced 2.5 m apart, plus tensioning with wire or clips. For a 40 m run of basic mesh around a suburban garden, the total cost of materials and labour follows directly from multiplying by local market rates; use the calculator with your actual quotation figures for accurate results.
Removable steel or aluminium palisade panels are the dominant choice for semi-detached and detached homes built post-1970s across the UK. They are factory-fabricated with galvanised or powder-coated finish, standard height 1.5 m. Durability spans decades with minimal maintenance; they occupy a medium-to-high price tier but repay the investment in longevity and appearance. Total cost with posts and labour sits clearly above mesh or timber options.
Timber fencing (vertical or horizontal boards in treated softwood or hardwood) is preferred for gardens with naturalistic or cottage aesthetics, particularly common in south-west and rural areas. Material cost is more accessible than steel panels; with timber posts and installation labour, it sits in a middle price band. Timber requires periodic treatment with exterior stain, varnish or wood preservative — a recurrent maintenance commitment that mesh or steel panels do not carry, and which must be factored into total cost of ownership. Durability depends on climate exposure, moisture conditions, and regularity of treatment.
Precast concrete panels offer complete visual privacy, durability exceeding 40 years, and maintenance effectively zero. Panels (typically 1 m high, available in smooth or textured finishes) sit at the top of the cost-per-metre scale. With support posts, foundation and installation, it represents the highest initial outlay but also the most durable choice. For gardens where visual privacy and decades of maintenance-free use are priorities, it is the rational long-term choice.
Posts and spacing: the detail that defines rigidity
For wire mesh and timber fencing, post spacing determines solidity and appearance. The standard interval used in the UK is 2.5 m between posts, which is adequate for 1 m height fencing on level ground. For taller fences (1.5–2 m) or in wind-exposed areas such as coastal locations or high ground, practitioners often reduce to 2 m spacing for increased rigidity. For a 40 m length at 2.5 m spacing, the formula yields approximately 17 posts. Rectangular hollow section steel posts (75 × 75 mm or 100 × 100 mm) or treated timber posts are available from builders' merchants; setting with concrete adds a cost per post that should be included in the total quotation.
Most UK installers quote by the linear metre already including posts in the rate. Always confirm exactly what is included (posts, concrete, fixings, labour) before comparing quotations from different suppliers.
What is never included in the per-metre price
Gates and entrance doors are never included in the per-metre fencing cost; they are always separate items. A pedestrian gate with hinges and catch, a vehicle entrance gate for car access, and any automation are three independent quotations that add to fencing cost. For an automated vehicle gate estimate, consult a dedicated calculator or specialist supplier.
Site preparation — levelling, post-hole excavation, groundwork — is frequently charged separately. On sloping or uneven ground with significant level change, that additional cost can be substantial and should be specified in your installer quotation.
Regulations: fencing height is set by local rules in the UK
Boundary fencing in the UK is subject to Building Regulations and local planning authority requirements, which vary by region and local authority. In England and Wales, planning authorities typically limit the height of boundary fences within a property's front setback (the area facing the street) to 1 m for the opaque portion, with a further transparent section permissible to approximately 2 m total height. Scotland operates under separate Building Standards with similar but distinct requirements. Northern Ireland has its own planning and building control framework.
These height limits may be stricter in conservation areas, areas of outstanding natural beauty, or for listed properties and their curtilages. Some local authorities maintain supplementary planning documents or conservation area appraisals that specify fencing requirements. It is essential to contact your local planning authority for the specific regulations that apply to your postcode and property type before purchasing materials. Failure to comply can result in enforcement action requiring removal or modification of non-compliant fencing.
When to hire a professional installer
For basic wire mesh on level ground to 30–40 m, a competent DIY builder with carpentry or construction experience can install successfully. For palisade panels with gates, precast concrete structures, sloping or uneven ground, or work on a shared boundary with neighbours, contracting a specialist installer is the safer and more economical choice long-term. Professional installers bring tools, equipment, site knowledge and accountability that reduce the risk of poor workmanship.
Always request 2–3 detailed quotations specifying material grades, post count, fixing method, and work guarantee. Confirm that the installer is properly qualified, holds public liability insurance, and (where applicable) is a member of a relevant trade association or scheme. Check references from previous installations in your area if possible.
Builders carrying out structural fencing work in the UK should hold appropriate qualifications and insurance. Verify that any installer you engage is competent and adequately insured before commencing work.
Frequently asked questions
How much does garden fencing cost per linear metre in the UK?
Total installed cost (materials and labour) varies significantly by type: galvanised wire mesh is the most economical; timber and steel panels sit at middle tiers; precast concrete is among the most expensive but most durable. Costs vary by region, supplier, access difficulty and ground conditions. Use the calculator with your own quotation figures for an accurate estimate.
Which type of fencing is cheapest for a garden?
Galvanised wire mesh is the lowest-cost installed option. It is durable and requires minimal maintenance. For those wanting visual privacy at moderate cost, timber fencing is a good alternative, though it requires periodic treatment with exterior stain or preservative. Steel panels and precast concrete have higher initial cost but superior longevity and lower ongoing maintenance burdens.
How many posts are needed for 40 metres of fencing?
At standard 2.5 m spacing between posts, 40 metres requires approximately 17 posts. For taller fencing (1.5–2 m) or in wind-exposed areas, reduce spacing to 2 m, which would require about 21 posts for the same 40 m length. Posts are available from builders' merchants; concrete setting adds a cost per post that should be included in your quotation. The calculator applies 2.5 m spacing automatically.
Is planning permission needed to install garden fencing in the UK?
In most cases, garden fencing within your boundary does not require planning permission, but is subject to local building control and height limits set by your local planning authority. In conservation areas, areas of outstanding natural beauty, or listed property curtilages, additional consent may be required. Specific rules vary by local authority and region. Always check with your local planning authority before purchasing materials.
Does timber fencing need a lot of maintenance?
Yes. Timber exposed to weather requires periodic treatment with exterior wood stain, varnish or preservative to prevent rot and deterioration, especially in areas with high rainfall and coastal exposure. The frequency of treatment depends on climate, exposure, and the wood species and treatment applied. Steel or aluminium panels, by contrast, last decades with minimal care beyond occasional cleaning.
When should I hire a professional fencing installer instead of DIY?
For simple wire mesh on level ground up to 30–40 m, an experienced DIY builder can manage successfully. For steel panels with gates, precast concrete structures, sloping or complex ground, or boundaries shared with neighbours, professional installation is the safer and more economical choice. Poorly installed fencing (posts out of plumb, mesh mis-tensioned, concrete inadequately founded) can fail structurally, creating liability and safety risks.
What building standards govern fencing height in the UK?
Fencing height is controlled by local planning authorities and building control regulations, which differ by region (England, Scotland, Wales, and Northern Ireland have separate frameworks). In England and Wales, boundary fences facing public roads are typically limited to 1 m opaque with a further transparent section to approximately 2 m total. Height limits may be stricter in conservation areas or for listed properties. Check your local authority's planning guidance for your specific postcode.
