Is it cheaper to buy fence panels or build them yourself? It’s a classic question for UK homeowners weighing up budget, time and finish. The short answer is: for most gardens, buying ready-made panels is usually the cheaper (and faster) route once you factor in your time, tool costs and wastage. However, building in-situ can be cost-effective when you need non-standard sizes, a premium closeboard specification, or perfectly follow tricky slopes. Below, we break down the true costs, show how to price a fence “per bay”, and help you decide which route fits your project—without surprises later.
What do we mean by “buy” vs “build”?
- Buy: Pre-manufactured panels (e.g., closeboard fence panels, waney lap, single slatted, double slatted, hit-and-miss, decorative) dropped in between posts. Add wooden or concrete gravel boards, and you’re done.
- Build: Assemble the infill on site from individual components—typically featheredge boards, rails and capping (a “stick-build” or in-situ closeboard). This is the traditional way to achieve a tailored, heavy-duty finish.
The real cost drivers (beyond headline prices)
- Materials: Panels are made at scale, so you benefit from factory efficiency. DIY builds require rails, many boards, capping, fixings and preservative.
- Posts & bases: Whichever route you take, you still need posts (choose concrete posts for longest life or timber posts for a warmer look) and gravel boards to lift timber off the ground.
- Tools: Panels need basic kit. Building from scratch usually needs a chop saw/circular saw, nailer or plenty of screws, clamps, and a bench.
- Wastage: Buying individual boards means offcuts and spares. Panels arrive ready-sized, so waste is minimal.
- Your time (labour): Assembly hours have a value—even for DIY. Building-in-situ typically takes 2–4× longer per bay than dropping in panels.
- Complexity: Slopes, curves, trees and odd spans can make stick-builds more sensible and sometimes cheaper overall, because panels need custom framing or many cuts.
At-a-glance: buy vs build
| Factor | Buy Panels | Build In-Situ (Closeboard/slatted) |
|---|---|---|
| Up-front cost | Usually lower per bay thanks to factory efficiency | Often higher due to many components + wastage |
| Time on site | Fast: drop-in install | Slow: measure, cut, fix each board/rail |
| Tools required | Basic hand/power tools | Additional saws, nailer/screws, clamps |
| Flexibility | Fixed sizes (1.83m wide typical) | Any span/height, follows slopes neatly |
| Quality potential | Consistently high from the factory | Excellent if built well; variable if not |
| Repairs | Replace a whole panel | Replace individual boards/rails |
| Look/finish | Neat, repeatable | Premium bespoke; tailored lines on slopes |
Costing a fence “per bay” (how to compare apples with apples)
Think in bays: one panel’s width (usually 1.83m) plus a post. A simple rear garden run might be six or seven bays. Cost both approaches for one bay, then multiply.
Option A: buy a ready-made panel per bay
- 1 × Panel (e.g., 6×6ft closeboard panel or 6×5ft if using a topper)
- 1 × Post (intermediate) – 8ft concrete post for 6ft panels
- 1 × Gravel board (wood or concrete) – e.g., 12" concrete board or 1.83m wooden board
- Fixings/capping as needed – panel capping, exterior screws, brackets
- Footings – post concrete
Option B: build a closeboard bay in-situ
- 2 × Posts (end + next intermediate) or 1 if counting shared posts per bay
- 3 × Rails (top, middle, bottom) – see square rails
- ~18–22 × Featheredge boards (for 1.83m span; see calculator below)
- 1 × Gravel board (wood/concrete)
- 1 × Capping – panel capping
- Nails/screws, preservative for cut ends, tools, plus your time
Ready-reckoner: how many featheredge boards do I need?
Featheredge is usually supplied ~100–150mm wide. You overlap each board to leave an effective cover of ~100mm per board. For a typical 1.83m bay:
- Boards needed ≈ 1830mm ÷ (effective cover per board in mm)
- If your boards give ~100mm effective cover → ~18–19 boards per bay
Allow 10–15% extra for cuts and defects, especially on long runs.
Example bill of materials (6ft rear garden bay)
| Item | Buy Panels | Build In-Situ | Notes |
|---|---|---|---|
| Main infill | 1 × 6×6ft panel (e.g., closeboard) | ~18–22 featheredge boards + 3 rails + capping | Rails align with post mortices or face-fixed |
| Posts | 1 × 8ft concrete intermediate | Shared per bay (as at left), but in-situ needs accurate layout | Concrete or timber; match your scheme |
| Base | Concrete or wooden gravel board | Same | Protects timber from damp & splashback |
| Fixings | Exterior screws, brackets | More fasteners (many boards), end-grain sealer | Allow for extra consumables when building |
| Footings | Post concrete (holes sized to wind exposure & post length) | Bell out hole bases for pull-out resistance | |
| Optional topper | Add 0.3–0.6m trellis toppers (e.g., privacy square trellis) | Great near patios—softer skyline, climbing plants | |
So… which really costs less?
In most cases: buying panels costs less per bay once you account for time, waste and tooling. Panels benefit from volume production, and installation is significantly quicker—often the difference between a weekend and several weekends. You’ll feel the savings especially with value-led ranges like waney lap or where you choose double slatted panels instead of building a slatted screen board-by-board.
When building can rival or beat panel costs: on steep slopes (to avoid stepping lots of panels), on awkward spans (non-standard widths) and for very heavy-duty closeboard where you want trade-grade rails and a bespoke, continuous run. In these cases, the material count can land close to an equivalent premium panel system—your time is the main extra cost, traded for a tailored finish.
Time = money: how long does each route take?
- Panel install: Set posts in concrete, drop in gravel boards and panels, fit capping—repeat. After the first bay, rhythm builds quickly.
- In-situ build: Measure/post set-out; cut and fix rails; set gravel board line; cut and fix each featheredge board with correct overlap; fit capping; repeat. Add time for calculations, cutting, and finishing.
If you’re DIY-only on weekends, panels usually win on total project duration, helping you avoid a half-finished boundary. If you enjoy the craft, the extra hours can be rewarding—and the result can be stunning.
Quality, durability & wind handling
Panels from a reputable supplier are made to consistent standards and pressure treated for longevity. Pair with concrete posts and concrete boards for the toughest setup. For exposed sites, consider air-permeable styles such as hit-and-miss or double slatted to reduce wind load. An in-situ closeboard with robust rails can be equally durable—provided cutting, fixings and treatment of cut ends are done meticulously.
Design flexibility: where building shines
- Slopes: Continuous closeboard follows gradients beautifully without stepping every bay.
- Odd spans & obstacles: Trees, sheds, or corners at unusual angles are easier when you’re not restricted to fixed panel widths.
- Mix & match: Combine solid sections with topper trellis for light and planting—browse fence topper trellis in privacy square, diamond or slatted.
Hidden costs people forget (and how to avoid them)
- Tools & blades: New blades, bits, and—if you’re nailing—gas/fuel or compressor hire.
- Consumables: End-grain sealer for cuts; extra screws/nails; brackets.
- Wastage: Order a little extra in case of knots/defects, especially for in-situ builds.
- Rework time: A mis-measured rail or uneven overlap can cost hours. Dry-fit the first bay.
Buying smart: panel choices that stretch the budget
If you’re leaning towards panels, pick a style that suits your plot and keeps upkeep simple:
- Maximum privacy & strength: closeboard panels (consider ultra heavy-duty for coastal/windy sites).
- Budget runs: waney lap with wooden gravel boards and capping for value and tidy lines.
- Wind-smart, modern look: double slatted or hit-and-miss.
- Front-of-house style: decorative panels with a matching garden gate.
When to build: scenarios where stick-build earns its keep
- Tricky gradients: You want a continuous line without “steps”.
- Non-standard spans: Bends, bays shorter/longer than 1.83m, or utilities to bridge.
- Premium spec closeboard: You prefer a trade-style rail and board arrangement with bespoke detailing.
- Repairability: You expect to swap a board here or there without removing whole panels.
Planning & height considerations
Rear boundaries typically sit around 6ft (1.83m). Many households opt for 5ft panels with a 1ft trellis topper for friendly sightlines. Near a highway or in front gardens, lower, decorative or picket styles look welcoming. If you’re increasing height significantly or working on shared boundaries, check local guidance and keep neighbours in the loop.
Installation essentials (whatever route you choose)
- Post depth: Bury roughly one-third of post length. For a 6ft fence, 8ft posts are typical.
- Footings: Use quality concrete and bell out the hole base for pull-out resistance.
- Gravel boards: Always lift timber off the ground—choose concrete for longevity or wooden for a unified timber look.
- Capping & rails: Fit panel capping or square rails to shed water and tidy the silhouette.
- Wildlife corridors: Consider the hedgehog-hole gravel board for eco-friendly connectivity.
Worked comparisons: three common projects
1) Six-bay rear boundary, straightforward plot
Cheapest overall: Buy panels. You’ll save hours and reduce wastage; installation is predictable. Pair closeboard panels with concrete posts and concrete boards for long-term value.
2) Sloping garden that drops across the run
Potentially cheaper: Build in-situ. You’ll save the visual “steps” and potential custom panel work. Your material cost may be close to premium panels; the trade-off is time.
3) Contemporary courtyard, windy setting
Cheapest & best-looking: Buy double slatted panels or hit-and-miss. Building a slatted screen board-by-board is labour-intensive; ready-made panels give consistent gaps and faster install.
Mistakes that make “build” more expensive than “buy”
- Under-estimating fixings: Hundreds of nails/screws add up quickly.
- Skipping cut-end treatment: Shortens life; false economy.
- Poor overlap on featheredge: Leads to gaps, rework and wasted boards.
- No datum line: A wavy top line means redo time—string a line and check each bay.
Blended approach: best of both worlds
Many projects mix methods: panels on long straight runs for economy and speed, then a short in-situ section to negotiate a tree, side return or tight corner. For neighbour-friendly privacy near patios, use a 5ft solid panel with a 1ft trellis topper—for example, 0.3m privacy square—to keep light and planting opportunities at the top.
Maintenance & lifecycle costs
Modern, pressure-treated timber keeps upkeep modest. Whichever way you build, a gentle annual wash, trimming back vegetation, and checking fixings prolongs life. Panels: replace a whole unit if damaged—fast and tidy. In-situ: repair single boards, but factor the time. Pair either with durable bases and posts (e.g., concrete posts, concrete boards) to extend service life and value.
Quick decision guide
- You want lowest cost + speed: Buy panels (waney lap for value, closeboard for strength).
- Your boundary is awkward/sloped: Consider building in-situ (closeboard) for a tailored line.
- You’re after a modern, airy look on a windy plot: Buy double slatted or hit-and-miss.
- You love DIY craft and custom details: Build; invest time for a premium finish.

FAQs
Is in-situ always stronger than a panel?
Not necessarily. A factory-built ultra heavy-duty closeboard panel on concrete posts and boards is extremely robust. In-situ closeboard is excellent too—but only if rails, overlaps, fixings and treatment are handled to a high standard.
Can I combine panels and trellis to save money?
Yes. A common, budget-friendly approach is 5ft solid panels topped with 1ft trellis (e.g., 0.3m privacy square trellis). You gain privacy without the mass of a full 6ft solid wall and keep installation simple and economical.
Do concrete posts make buying panels more expensive?
Concrete posts cost more than timber but last longer and keep lines straighter over long runs. They also allow easy panel swap-outs later, saving future maintenance costs. Browse concrete posts to compare sizes and types (intermediate, corner, end).
Can I repair a panel rather than replace it?
Minor damage can sometimes be braced, but panels are designed as a unit. Many homeowners prefer the speed and cleanliness of replacing a single panel bay. If you value part-by-part repairs, in-situ closeboard gives you that granularity.
The bottom line
For most households, buying ready-made fence panels is the cheaper and faster way to achieve a smart, durable boundary—especially on straight, standard runs. Build in-situ when your plot demands custom work, you want a premium closeboard look that follows slopes elegantly, or you simply enjoy the craft and are happy to invest the time.
Whichever path you pick, build a coherent system: choose posts that suit your exposure and look, lift timber with gravel boards, add capping to finish the line, and consider neighbour-friendly trellis toppers where you want light and greenery.
