How to Price a Fencing Job in the UK

To price a fencing job, measure the proposed fence, calculate the materials and labour needed, include site expenses and business overheads, then add your planned profit. Apply VAT where appropriate. A good fencing quotation covers the entire agreed job, not just the panels and the time spent fitting them.

Small details can change the price significantly: a narrow access route, concrete foundations from the old fence or a gate in the middle of a run all affect the work. This guide shows how to build a price from your own costs, with an itemised 18-metre example.

Build your fencing price from costs, overheads and profit

Start with the cost of delivering the finished job, then work towards the price you will charge. Keep the calculation in your internal records even if your customer only needs a few clear quotation lines.

Direct job costs + allocated business overheads + planned profit = selling price before VAT

Direct costs normally include materials, your own labour and any employees or subcontractors, equipment hire, delivery, travel and disposal. Overheads are the running costs of your business that cannot easily be attributed to one job, such as insurance, accountancy, phones and general tool replacement.

One way to recover overheads is to divide your estimated annual overhead budget by realistic annual chargeable hours, then allocate a proportion to each job. Don't add those costs twice: if your internal labour rate already includes an allowance for overheads, account for that when building the final price.

Markup is not the same as profit margin

A 20% markup on a £100 cost produces a selling price of £120. The £20 profit is 16.7% of the selling price, so the margin is 16.7%, not 20%.

To calculate a selling price from your target profit margin, first convert the percentage to a decimal by dividing it by 100. For a 20% target margin, use 20 ÷ 100 = 0.20.

Selling price = full job cost ÷ (1 − target margin as a decimal)

For example, with a £1,000 full job cost and a 20% target margin:

£1,000 ÷ (1 − 0.20) = £1,000 ÷ 0.80 = £1,250 before VAT

This leaves £250 of planned profit, which is 20% of the £1,250 selling price. The remaining 80% covers your £1,000 costs. This is planned gross job profit after the costs included in your calculation, not necessarily the business's final net profit after every expense and tax.

Account for VAT correctly

For an ordinary standard-rated installation, a VAT-registered contractor adds VAT at the applicable rate to the selling price. The standard UK rate is currently 20%. A VAT-registered business using normal VAT accounting will generally cost recoverable input VAT separately rather than treating it as an expense. A non-VAT-registered contractor must not add VAT to the customer invoice and should include any irrecoverable VAT in its own purchasing costs. Check the treatment of unusual work with an accountant or HMRC. See GOV.UK's VAT charging guidance.

Measure the run and agree the fence specification

Visit the site before issuing a firm fixed quotation. Record each straight run, its length, finished height, changes of direction, existing structures and any gates. Sketch the layout and label the dimensions: the total length alone is not enough to order the right materials.

Check what the customer actually wants. A standard lap-panel fence, a closeboard fence built on site, and a panel fence with concrete posts have different material lists and labour requirements. Specify the panels or boards, post material and dimensions, gravel boards, fixings and finish. Gates need their own measurements, supporting posts, hinges, latch and fitting allowance.

Pay particular attention to:

• Sloping or uneven ground: stepped panels, raked fencing and changes in finished height may require additional cutting or a different system.
• Access: narrow side passages, steps and long carrying distances increase handling time and may rule out certain machinery.
• Existing fencing: dismantling, buried concrete, roots and disposal can be substantial parts of the job.
• Ground conditions: difficult digging, unstable ground or buried obstructions may alter the installation method.
• Boundaries and permissions: ask the customer to confirm the fence line, their authority to approve the work and any required neighbouring access.

Check for underground services before digging and plan safe excavation. The HSE's guidance on underground services explains the need to plan the work, locate services and dig safely.

Planning requirements also depend on the property and location. For example, in England the usual permitted-development height limits are 1 metre next to a highway used by vehicles (including its footpath) and 2 metres elsewhere, subject to further restrictions and exceptions. Do not treat those figures as blanket permission for every site, particularly listed properties or locations with planning conditions. Check the Planning Portal's fencing guidance and the relevant local authority; rules differ across UK nations.

Calculate fence materials from the actual layout

Work out the bay arrangement before using a price per panel or per metre. A typical manufactured panel is approximately 1.83 metres (6 feet) wide, but you must check its actual dimensions and the fixing clearances for the system you intend to install.

For a new, independent straight fence with no gates, the basic relationship is:

Number of posts = number of bays + 1

That assumes separate posts at both ends. Corners, gates, existing posts and different construction systems change the count. Remember that the run includes the physical width of the posts, so dividing its overall length by 1.83 metres is only a preliminary estimate of the number of panels.

Panels, gravel boards and closeboard materials

Count the panels you need to buy, not just the number of full-width panels you will install. If two bays require shorter panels, you may still need to purchase two complete panels and cut and reframe them, provided the product is designed to allow this.

Allow for one gravel board per panel bay where that is part of the specification. For closeboard or feather-edge fencing built on site, calculate the posts, rails, gravel boards and individual boards separately. For feather-edge boards, divide the length to be covered by the effective cover width after overlap, round up to whole boards and allow for cuts where justified.

Posts, concrete and fixings

Specify the post length from the finished fence height and the required embedment, rather than assuming any off-the-shelf post will do. Foundation dimensions depend on the fence system, ground conditions, loading and manufacturer guidance.

For a simple square hole, you can estimate the post-setting mix needed as:

Mix volume = (hole width × hole length × depth) − volume of post within the hole

Multiply by the number of holes, then convert the volume into bags using the actual yield of the selected product. Do not assume that one bag per post works for every hole size. Also count clips, brackets, screws, caps, cut-end treatment and any materials needed to reinforce cut panels.

Finally, add supplier delivery, unloading or collection costs. Account for unavoidable offcuts and the quantities you must purchase, but don't add the same waste allowance again after you have already counted full panels for cut bays.

Estimate installation labour and site expenses

Estimate labour as person-hours, not just days on site. Two people working eight hours each account for 16 person-hours, whether they finish in one day or split the work over several visits.

Break the job into tasks: protecting access routes, removing the old fence, excavating and setting posts, fitting boards and panels, making cuts, installing gates where required, loading waste and clearing the area. Include your own time at a realistic internal cost and distinguish that cost from your customer-facing charge-out rate.

Add expenses that aren't covered in your labour figure: equipment or breaker hire, consumables, travel, material deliveries and commercial waste disposal. Compare your estimate against actual hours and costs from completed jobs to improve future pricing.

Waste from dismantling a fence is not automatically ordinary household waste because it came from a domestic garden. Check the appropriate rules for your UK nation, whether you need waste-carrier registration, and the requirements for a lawful transfer and disposal. In England, construction and demolition waste can affect which registration tier applies. Start with GOV.UK's business waste guidance.

How to handle unknown ground conditions

Price visible complications in the base job. For genuine unknowns, state your assumptions and exclusions clearly—for example, the treatment of extensive buried concrete not visible at survey. Explain how additional work would be assessed and agree changes to scope and price before proceeding, rather than assuming you can automatically add a charge after the customer accepts a fixed quote.

Per-metre, per-panel or fixed-price fencing: which is best?

All three approaches can be useful, but they serve different purposes.

A per-metre rate should normally be derived from your full job calculation, not used as a substitute for it. Say whether a rate is labour-only or fully installed, and whether it includes VAT. Price gates and other distinct extras separately if they are not part of the quoted run.

Worked example: an itemised 18-metre fencing quotation

The following is an illustrative costing exercise, not a current supplier quote or an industry price benchmark. Materials, unit costs, productivity and overheads are assumed. Check your own site survey, supplier prices and product instructions before using any figures for a real customer.

1. Fence specification and checked quantities

Assume a straight, independent fence measuring 18.00 metres between the outside faces of the two end posts, on level ground with clear side access. The work includes dismantling the existing timber fence and removing its agreed foundations. There are no gates or corners.

The replacement uses 100 mm-square timber posts, 1.80-metre-high panels and 150 mm gravel boards, producing a nominal 1.95-metre finished height. The example assumes posts approximately 2.70 metres long to allow 750 mm embedment; actual lengths and foundation design must be confirmed for the site and product.

Rather than leave one very narrow final bay, the layout uses eight full-width bays and two equal shorter bays:

This means 10 panel bays, 11 posts, 10 purchased panels and 10 gravel boards. Two panels and two gravel boards are cut to suit the shorter bays. Confirm actual fitting gaps, post dimensions and whether the chosen panels can safely be cut and reframed.

2. Material take-off and internal costs

For this example alone, assume eleven square holes of 250 × 250 × 750 mm, with a 100 × 100 mm section of each post occupying the full 750 mm depth. The net mix volume is:

11 × [(0.25 × 0.25 × 0.75) − (0.10 × 0.10 × 0.75)] = 0.433125 m³

Allow approximately 0.45 m³ for purchasing. Using an illustrative yield of 0.009 m³ (9 litres) per 20 kg bag gives 50 bags. For comparison, Tarmac's published Postmix technical information gives coverage equivalent to approximately 9 litres per 20 kg bag. Confirm the current yield and suitable application of the actual product purchased; other post mixes may differ. The assumed £7.50 per bag is an example cost, not a verified current retail price.

All internal costs below are illustrative and exclude recoverable VAT, on the assumption that the contractor is VAT registered and using normal VAT accounting.

3. Labour and other job costs

Allow 32 person-hours, equivalent to two installers working two eight-hour days, at an assumed £25 per person-hour internal cost. This is an example resource allowance, not a promise that every 18-metre replacement can be completed in two days.

Add the following job-specific expenses:

Direct job cost = £1,340 materials + £800 labour + £340 expenses = £2,480.

4. Overheads, profit and VAT

Assume the £25 internal labour cost does not already recover overheads or profit. Allocate £240 of business overheads to the job, then apply a 25% markup to the full job cost.

The planned job profit margin is 20% (£680 ÷ £3,400). The equivalent selling price is £188.89 per metre before VAT (£3,400 ÷ 18), or approximately £226.67 per metre including VAT. Neither figure is a recommended market rate: it only reflects the assumptions in this worked example.

5. Example customer-facing quotation

The contractor does not need to reveal supplier unit costs, internal labour rates or the markup calculation. The same total can be organised into understandable selling-price lines. Here, the £240 overhead allowance is included within installation labour before the 25% markup is applied to each cost group.

The quotation should also identify the 18-metre run, fence type and height, two shorter bays, timber posts, gravel boards, removal work, ground assumptions and exclusions. The table alone does not define the full contract.

Turn the calculation into a professional fencing quote

A clear fencing quote makes it easy for the customer to understand what is being installed, what is included and what they will pay. Use descriptions specific enough to distinguish one proposed fence from another. State whether old fencing, foundation removal, waste disposal, gate work or making good are included.

Set out any exclusions and the process for agreeing variations. Include the customer's details, property address, proposed timing, deposit or payment stages where applicable, issue date and a quote validity period. Be mindful that consumer-contract requirements, including cancellation information in relevant circumstances, can apply when dealing with domestic customers.

Once your costs and selling prices are checked, Quote Forge can help you prepare a branded, itemised quotation, reuse saved line items, apply a quote-level VAT percentage where required, and preview or download the finished PDF. The detailed site measurement and costing still need to be done properly; the software is for organising and presenting the quote, not automatically designing the fence or estimating ground conditions.

Frequently asked questions

How do you calculate labour cost for fencing?

Estimate person-hours for preparation, removal, digging, post setting, panel fitting and clearance. Multiply those hours by your internal labour cost, then account for overheads and planned profit without double counting.

How do you price a fence repair?

Inspect the damaged bay and neighbouring posts, then cost the materials, removal, labour, travel and disposal required. A single-panel replacement with sound existing posts is a different job from replacing a rotten post and its foundation.

Can a fence cost calculator replace a site visit?

No. A calculator can provide a useful preliminary take-off or budget, but it cannot confirm the actual fence line, underground services, levels, site access or condition of old foundations.

How much should you charge for a small fencing job?

Base the price on the full cost of attending and completing it. Travel, collecting materials, setup and disposal still take time on a one-panel job. A clearly explained minimum charge may be appropriate to your business.

Should customers see your material costs and markup?

Usually they need the agreed specification and selling prices, not your supplier invoices or internal calculations. If you agree to an open-book arrangement, make the basis of cost and fee disclosure clear from the start.

Check the full scope before sending

Before you send a fencing quotation, confirm that the bay layout matches the purchasing list, that labour and disposal reflect the site, and that the price includes overhead recovery and planned profit. The goal is not just to win the job: it is to give the customer a clear commitment that your business can deliver profitably.
