Karndean Luxury Vinyl Flooring Installation Costs

Karndean is one of the UK's best-known luxury vinyl tile (LVT) brands, and homeowners regularly encounter it when choosing flooring for kitchens, hallways, bathrooms, and open-plan living areas. The brand sits firmly in the premium segment, and costs reflect that — but so does the product specification, warranty length, and breadth of design options. Understanding the cost breakdown before requesting quotes helps you assess whether a quote is competitive and which variables will push the total up or down in your specific property.

Key points

• Karndean material costs typically range from around £30 to £75+ per m² depending on the product range, with premium Korlok and Opus ranges at the upper end (indicative UK costs, last reviewed 2026-05-07).
• Professional installation adds roughly £15–£35 per m² on top of material costs; rates vary by region, project size, subfloor condition, and pattern complexity.
• Subfloor preparation — including levelling compound, plywood overlay, or a damp-proof membrane — is a major cost variable and is not always included in a base installation quote.
• Most Karndean ranges are compatible with underfloor heating (UFH), but product-specific surface temperature limits must not be exceeded; doing so can void the manufacturer warranty.
• Residential warranties range from 15 to 25 years depending on the range, which is a meaningful differentiator against budget LVT products that commonly carry 5–10 year warranties.

Which Karndean range is right for your project?

Karndean produces several product lines with different specifications, price points, and installation methods. The right range depends on your subfloor type, whether you have underfloor heating, expected foot traffic, and the aesthetic you are after.

What does professional installation cost?

Installation is typically priced in one of two ways:

• Per m² rate: most UK fitters charge £15–£35 per m² for labour, depending on region, project size, and complexity of the layout
• Day rate: some fitters quote £200–£400 per day; this may work out cheaper for smaller rooms with straightforward subfloors
• Minimum call-out: many fitters apply a minimum charge equivalent to approximately 15–20 m², making small or single-room jobs proportionally more expensive
• London and South East premium: typically 20–35% above national average rates

For a typical kitchen of around 15 m² using Van Gogh materials and standard installation, combined material and labour costs might range from £800 to £1,400 — though actual quotes will vary by fitter, region, and subfloor condition.

What subfloor preparation adds to the total

Subfloor preparation is where costs often escalate beyond initial estimates. Karndean's installation guidelines require a flat, dry, and fully adhered subfloor; most glue-down ranges require flatness to within 3 mm over a 1.8 m span.

Common additional costs:

• Plywood overlay (6–18 mm): £8–£18 per m² for ply plus labour — typically required over suspended timber floors
• Levelling compound: £5–£15 per m² depending on depth and area
• Damp-proof membrane (DPM) or additive: £5–£12 per m² if damp is detected in a concrete slab
• Existing floor covering removal: £3–£10 per m² depending on type and thickness

Always ask contractors to inspect the subfloor before providing a final quote, not after work has started. Discovering a wet slab or uneven surface mid-installation is a common cause of cost overruns and delays.

Homeowner checklist: preparing for installation quotes

Use this checklist before inviting fitters to quote:

• Measure the room area accurately (length × width in metres); add 10% for wastage and pattern matching
  
• Identify the subfloor type: concrete slab, suspended timber floor, or existing tiles
  
• Check for visible damp, hollow areas, springy boards, or surface cracks — these affect preparation costs
  
• Decide between glue-down and click-lock (Korlok); this affects underfloor heating compatibility advice
  
• Confirm whether UFH is present and whether it is wet (pipe) or electric (mat)
  
• Check whether furniture removal and replacement is included in each quote
  
• Note awkward areas: doorways, curved walls, kitchen islands, staircase thresholds, and changes in floor level
  
• Ask each fitter about their specific experience fitting your chosen Karndean range
  
• Clarify whether the fitter supplies materials or whether you purchase directly from a supplier
  

What to ask before accepting a quote

• Is subfloor preparation included, and what assumptions does this quote make about the current subfloor condition?
• Who supplies the Karndean material — you or the fitter — and is this price based on trade or retail pricing?
• Is the wastage allowance factored into the quoted m² cost?
• What experience do you have fitting this specific Karndean range?
• How will doorway thresholds, trims, and skirting boards be handled, and are these included in the price?
• Is VAT included in this quote?
• What is your process if subfloor issues are identified once work begins — and how are additional costs agreed?
• Do you handle Karndean installer warranty registration, or does the homeowner register directly with Karndean?

Is Karndean worth the premium over budget LVT?

Karndean occupies the upper-mid to premium segment of the UK LVT market. The practical differentiators over budget alternatives include:

• Thicker wear layers (0.3–0.55 mm versus 0.1–0.2 mm on many budget products) — meaningful in high-traffic hallways and kitchens where surface scratching is a concern
• Residential warranties of 15–25 years versus 5–10 years on many budget alternatives
• Dimensional stability — Karndean glue-down products are engineered to minimise expansion and gapping in centrally heated UK homes where temperature fluctuates seasonally
• UK trade network — products are available through UK trade suppliers with a local fitter accreditation programme

Whether the premium is justified depends on the room's expected traffic, your tenure in the property, and whether quality flooring is a selling point for a future buyer. For kitchens and hallways in a home you plan to occupy for ten or more years, the cost difference over budget LVT may represent reasonable long-term value.

If you are fitting flooring as part of a wider build — such as a new extension — coordinate with your extension builders early to ensure the subfloor is laid to the correct specification and given sufficient time to cure before the flooring contractor arrives. If recent roofing work has been completed by roofers, confirm there is no residual moisture ingress through the roof or walls before committing to a premium floor finish over any affected subfloor area.

When to get professional help

Karndean installation — particularly glue-down products — should always be carried out by a qualified fitter. Errors in adhesive application, insufficient subfloor preparation, or failure to follow the product's acclimation requirements can cause lifting, bubbling, or gapping that may not be covered under warranty if installation was not carried out correctly.

If your subfloor has active damp, significant unevenness of more than 5 mm, or signs of structural movement, address those problems before committing to any premium floor finish. Look for fitters with demonstrable LVT experience or accreditation through Karndean's trade programme.

Frequently asked questions

How much does it cost to fit Karndean in an average kitchen?

For a typical kitchen of around 15 m², combined material and labour costs commonly fall in the range of £750–£1,500, depending on the range chosen, subfloor preparation required, and location. Subfloor issues — particularly on older properties with suspended timber floors or damp concrete slabs — can push costs higher. Always obtain at least three itemised quotes and check whether subfloor preparation is included.

Can Karndean be fitted over underfloor heating?

Most Karndean ranges are compatible with both wet (pipe) and electric (mat) underfloor heating systems. However, maximum surface temperature limits apply — generally 27°C for most glue-down ranges. Always check the specific product technical data sheet before installation, and ensure your UFH installer and flooring fitter communicate clearly on heat-up and cool-down schedules.

How long does Karndean installation take?

A standard room of 15–25 m² typically takes one to two days including subfloor preparation. Larger open-plan areas or complex layouts with multiple tile orientations may take two to three days. Materials should be left to acclimatise in the installation room for 24–48 hours before fitting begins.

Do I need to remove existing floor coverings before Karndean installation?

Existing coverings must generally be fully removed before glue-down Karndean installation — the subfloor must be sound, clean, and flat. Some Korlok click-lock products can be installed over certain existing hard floors if they are flat and stable, but this should be confirmed with your fitter and checked against Karndean's current installation guidelines.

Is Karndean suitable for bathrooms and wet rooms?

Yes. Most Karndean products are 100% waterproof. However, the subfloor must be dry, and appropriate silicone sealing around baths, shower trays, and cisterns is still required to prevent water ingress beneath the floor. The Da Vinci range is a popular choice for stone-effect bathroom floors in UK homes.
