- Cheapest overall: Nordic spruce feather edge 14mm — from £21.20/m². Requires preservative treatment every 2–3 years.
- Cheapest naturally durable: Siberian larch feather edge — from £50.39/m². No treatment needed, 20–30 year service life.
- Cheapest profile in any species: Feather edge — least machining, least waste, lowest price.
- Best budget strategy: Nordic spruce on sheltered rear elevations, Siberian larch on primary visible elevations.
- Whole-life cost warning: Maintained spruce costs £65–105/m² over 30 years. Larch costs £35–65/m². Larch is cheaper over time.
Cheap and good value are not the same thing in timber cladding. The cheapest boards upfront can become the most expensive over 10–20 years if the wrong species is specified or the maintenance obligations are not met. This guide gives you an honest breakdown of every affordable timber cladding option in the UK in 2026 — what each costs, what it requires, and where the hidden costs lie — so you can make the right budget decision for your project.
Nordic spruce cladding on a UK building — the most affordable natural timber cladding specification from £21.20/m². The right choice for budget projects where a committed treatment programme will be maintained. Pre-treated grey or black finishes are also available for an immediate colour and extended first treatment interval.
The Cheapest Timber Cladding — Nordic Spruce from £21.20/m²
Nordic spruce is the cheapest timber cladding species available in the UK — consistently 50–60% cheaper than Siberian larch or ThermoWood at equivalent profiles. The lower cost reflects its natural durability rating (Class 4 — not durable without treatment) rather than any deficiency in its visual quality or performance when correctly specified. Here is every available Nordic spruce profile, ranked by price:

Upfront vs Whole-Life Cost — The Most Important Distinction
Naturally weathered cladding on a UK garden room — the silver-grey patina of uncoated larch after 3–5 years. No maintenance cost, no treatment cost, no treatment scaffold. Over 30 years, naturally durable larch costs significantly less in total than regularly treated Nordic spruce despite the higher upfront price.
| Species / scenario | Upfront/m² | 30-yr maintenance/m² | 30-yr total/m² | Verdict |
|---|---|---|---|---|
| Spruce feather edge — maintained | £21–30 | £45–75 (10 treatments) | £65–105 | Acceptable if treatment maintained |
| Spruce feather edge — unmaintained | £21–30 | £80–150 (early replacement) | £100–180 | Most expensive outcome |
| Siberian larch feather edge | £50–63 | £0–15 (optional oil) | £35–65 | Best whole-life value |
| ThermoWood shiplap | £50–65 | £0 | £50–65 | Best zero-maintenance spec |
Maintained Nordic spruce costs approximately £65–105/m² over 30 years. Unmaintained, it can reach £180/m² once early replacement, scaffold, and disposal are included. Siberian larch at £35–65/m² over 30 years is genuinely the best-value cladding in the UK. The upfront price difference of £29/m² between spruce and larch is recovered after just 2–3 treatment applications of spruce — typically within 6–8 years.
Budget Strategies — 5 Ways to Reduce Cladding Cost
In any species, feather edge is the cheapest profile — least machining, least waste. Switching from shadow gap to feather edge in Siberian larch saves approximately £7–12/m² — on an 80m² house that is £560–960 on materials alone.
Use Siberian larch on primary visible elevations where durability matters most, and Nordic spruce on sheltered rear elevations where maintenance access is easy. Reduces material costs by 20–30% on a full house.
Timber cladding is significantly cheaper in full packs versus cut packs. If your project is close to a full pack quantity, rounding up avoids the cut-pack premium — excess boards store for future repairs. Contact us for current pack sizes before ordering.
Installation labour is 30–40% of the total installed cost. Self-installing saves £25–45/m² — typically £1,000–2,000 on a garden room. See our how to clad a house guide and our full installation guide.
Autumn and winter installation slots are typically 10–20% cheaper on labour than spring/summer. Material costs are consistent year-round. Booking off-peak saves money without any quality compromise.
What to Avoid — False Economies in Cheap Cladding
Nordic spruce exterior cladding correctly treated and performing well — affordable cladding done right. The false economies below turn a low upfront cost into a high total cost. All of them are avoidable with the correct specification from the start.
1. Untreated construction softwood — C16/C24 framing timber is not rated for exterior use. It fails within 3–5 years. 2. Cheap galvanised fixings — saving £20 on fixings leads to rust staining within 2 years and fixing failure over time. A4 stainless only. 3. No breather membrane — saves £3–4/m² but risks structural frame decay costing thousands. 4. No end grain sealing — a £15 tin of sealer protects every cut end. Without it, moisture entry causes early splitting. 5. Nordic spruce without a maintenance plan — only specify spruce if treatment every 2–3 years will genuinely happen. Without it, early failure is certain.
Budget Black Cladding — Charred SSB from £60.39/m²
What is the cheapest timber cladding in the UK?
Nordic spruce feather edge 14mm at £21.20/m² is the cheapest timber cladding in the UK upfront. However Siberian larch feather edge at £50.39/m² is cheaper over a 20–30 year period because it requires no ongoing preservative treatment — making it the best budget cladding on a whole-life cost basis.
Is cheap timber cladding worth it?
Nordic spruce is worth it for sheds, outbuildings, and garden rooms where treatment every 2–3 years will genuinely be maintained. For permanent buildings where maintenance access is difficult or unlikely, the saving is lost within 10–15 years through treatment costs or early replacement. On most houses, Siberian larch is the better budget choice on a whole-life basis.
What is the cheapest profile for timber cladding UK?
Feather edge is the cheapest profile in any timber species — least machining, least waste in production. Nordic spruce feather edge 14mm at £21.20/m² is the cheapest profile overall. Shiplap is next, followed by loglap, then shadow gap. Switching from shadow gap to feather edge in Siberian larch saves approximately £10–12/m² with identical natural durability and service life.
How can I reduce the cost of timber cladding?
Most effective ways: choose feather edge or shiplap over shadow gap; use Nordic spruce on sheltered rear elevations and Siberian larch on primary visible elevations; order in full pack quantities to avoid cut-pack premiums; self-install rather than using a contractor (saves £25–45/m²); and book installation in late autumn or winter when labour rates are lower.
What is the cheapest naturally durable timber cladding UK?
Siberian larch feather edge at £50.39/m² is the cheapest naturally durable timber cladding in the UK — Class 3 naturally durable, no preservative treatment required above ground, 20–30 year service life. Despite the higher upfront cost versus Nordic spruce, the zero maintenance overhead makes it cheaper over a 20+ year period for most projects.
