Dekton Worktop Cost UK 2026: Real Prices from Our Fabrication Team
Quick verdict: Dekton runs £350–£700/m² supplied and fitted in 2026 UK. For a typical 6m² kitchen, expect £2,100–£4,200 total. Premium colours and outdoor installs reach £4,500+. Dekton sits 20–40% above quartz, 30–50% above granite — the premium reflects extreme heat resistance, UV stability, and ultra-compact engineering.
This guide is written by the Stoned Collective fabrication team based on real 2026 Dekton installations across Watford, Northampton and High Wycombe. We see Dekton priced wildly differently across UK suppliers — this is the honest breakdown.
After thousands of kitchen installations, Dekton confuses customers more on price than any other surface. One supplier quotes £2,500 for the same kitchen another supplier prices at £4,800. The difference is almost always slab grade, fabrication quality, and what’s hidden in the “extras” line. This guide shows you exactly what the £350–£700/m² range covers, what it doesn’t, and how to compare two Dekton quotes fairly.
Dekton price per m² (UK 2026, supplied + fitted)
| Dekton Tier | Per m² supplied + fitted | Typical 6m² kitchen total |
|---|---|---|
| Solid colours (Sirius, Halo, Zenith) | £350–£450 | £2,100–£2,700 |
| Concrete-effect (Kreta, Bromo, Lunar) | £400–£500 | £2,400–£3,000 |
| Marble-effect (Aura, Opera, Bergen) | £450–£600 | £2,700–£3,600 |
| Stone-effect (Sasea, Kelya, Rem) | £500–£650 | £3,000–£3,900 |
| Premium Liquid Series (Liquid Sky, Liquid Embers, Liquid Shell) | £600–£750 | £3,600–£4,500 |
| Bookmatched / outdoor grade | £650–£900 | £3,900–£5,400 |
For context: premium quartz sits £400–£700/m², granite £300–£550/m², and real marble £500–£1,000+/m². Dekton’s middle tier matches premium quartz prices but with stronger heat performance.
What’s actually in the price
Slab cost (45–55% of total)
Cosentino (the only Dekton manufacturer) prices slabs in tiers. Standard solids start around £200/m² slab cost; premium veined and Liquid Series ranges reach £400–£500/m². UK distributors add 15–25% margin.
Fabrication (20–25%)
Here’s where Dekton differs from quartz/granite: the material is significantly harder to cut. It requires diamond-impregnated blades, wet cutting with precise feed rates, and specialized handling to prevent edge chipping. Expect £80–£140/m² fabrication on Dekton versus £40–£80/m² on quartz. Only experienced fabricators should cut Dekton.
Installation (15–20%)
Two-person install. Dekton is denser than quartz (more weight per m²) but thinner (12mm or 20mm vs quartz 20mm/30mm), so handling is comparable. Allow £30–£80/m² install, plus £200–£500 base fee depending on kitchen complexity.
Edge profiles & cutouts
- Standard square edge: included
- Mitred 90° (chunky look): £100–£160/linear metre on Dekton (vs £80–£140 on quartz)
- Undermount sink cutout: £150–£250 per cutout
- Hob cutout: £80–£150
- Drainage grooves: £100–£180
Cost by kitchen size
| Kitchen size | Worktop m² | Mid-range Dekton total |
|---|---|---|
| Small galley | 3–4 m² | £1,400–£2,200 |
| Average UK kitchen | 5–6 m² | £2,100–£3,600 |
| Medium open-plan | 7–9 m² | £3,000–£5,400 |
| Large with island | 10–14 m² | £4,500–£8,400 |
| Extension / pro kitchen | 15–25 m² | £6,750–£15,000 |
| Outdoor kitchen counter | 2–5 m² | £1,300–£3,250 |
Hidden costs that surprise people
- Old worktop removal: £100–£250
- Electrical disconnect/reconnect: £100–£200 (cooker hood, hob, undercounter lights)
- Plumbing disconnect/reconnect: £80–£150
- Carpentry adjustments: £100–£300 if cabinet trimming needed
- Sink + tap purchase: £150–£600 not included in worktop quote
- Mitred 90° edge for “chunky” look: +£100–£160/linear metre
- Bookmatched veining match: +£300–£800 on premium Liquid/Marble effect colours
Always request itemised quotes. A £3,200 Dekton quote and a £4,500 Dekton quote may be quoting different colour tiers, different edge profiles, and different extras — they’re not directly comparable until itemised.
5 ways to lower your Dekton bill (without cutting corners)
- Choose solid or concrete-effect over Liquid Series: Same performance, 30–40% cheaper. The Liquid Series is purely aesthetic premium.
- Use 12mm Dekton with substrate instead of 20mm solid: 15–20% cheaper, identical performance for most kitchens.
- Square edge instead of mitred 90°: Saves £100–£160/linear metre.
- Top-mount sink instead of undermount: Saves £80–£150 per cutout.
- Get itemised quotes from 3 fabricators: Margins vary 20%+ even for identical specs.
When Dekton is worth the premium over quartz
- You cook seriously. Hot pans straight from the hob land safely on Dekton (600°C+). Quartz scorches at 150°C — you need trivets.
- Outdoor kitchen. Dekton has full UV stability. Quartz yellows under sustained sun.
- Slim profile design. 12mm Dekton enables ultra-modern thin worktops and seamless splashbacks. Quartz minimum is 20mm.
- Industrial / commercial. Dekton’s chemical and abrasion resistance handle catering, cafe, or workshop use that would damage quartz.
- You want the highest-end aesthetic. The Liquid Series creates effects no other material delivers — bookmatched metallic, rusty patina, abstract marble — at £600–£800/m².
For 70% of UK kitchens, quartz delivers identical day-to-day performance at lower cost. The Dekton premium pays back specifically for heavy cooks, outdoor installs, and designer aesthetics. See our full Dekton vs Quartz comparison.
Frequently asked questions
How much does a Dekton worktop cost UK 2026?
For a typical 6m² UK kitchen, £2,100–£4,200 supplied and fitted with mid-range Dekton. Premium Liquid Series colours reach £3,600–£4,500. Larger or premium installs go to £5,000+.
Is Dekton more expensive than quartz?
Yes, typically 20–40% more. Mid-range quartz £300–£450/m² vs mid-range Dekton £400–£600/m². The premium is for heat resistance, UV stability, and slim profile capability.
What’s the cheapest Dekton colour?
Solid colours in the Tech Range — Sirius, Halo, Zenith — start around £350/m² supplied and fitted. These deliver Dekton’s performance benefits at the lowest tier pricing.
Why are some Dekton quotes £1,500 and others £4,500 for the same kitchen?
Almost always: different colour tier, different edge profile, missing extras (cutouts, removal, install), or one quote is from an inexperienced fabricator. Always compare itemised quotes from established UK fabricators.
Can I get Dekton on a £2,000 budget?
Yes for small kitchens (3–4m²) in entry-tier solids. Below that budget for a 6m² kitchen, you’d need to accept entry colours only — at which point premium quartz may deliver better aesthetic value.
How long does Dekton installation take?
10–14 working days from order: slab order in (3–5 days), templating (1 day), fabrication (5–7 days for Dekton — longer than quartz due to material hardness), installation (1 day).
Is Dekton worth it for a typical UK kitchen?
Worth it if you cook seriously, want outdoor installation, or specifically need the Liquid Series aesthetic. For standard daily kitchen use, quartz delivers 95% of Dekton’s benefits at lower cost.
Does Dekton chip easily?
The surface is extremely hard (Mohs 7-8) and won’t scratch from normal use. Edges are more brittle than quartz — heavy dropped objects can chip a Dekton edge where quartz would just shake it off. Mitred edges and reinforced corners help.
