LVT in London Renovations: When It Is the Right Choice and How to Specify It

Luxury vinyl tile — LVT — occupies an interesting position in the specification hierarchy. A decade ago it was viewed as an inferior substitute for natural stone or timber, used where budget did not allow the real thing. That perception has shifted. In certain applications, LVT is genuinely the correct specification — not a compromise, but the right answer for the conditions. Understanding when that is, and what distinguishes a well-specified LVT from a poor one, is the difference between a floor that performs for 20 years and one that looks tired in three.

What LVT is

Luxury vinyl tile is a multi-layer synthetic flooring product. From bottom to top, a typical LVT construction consists of a backing layer, a core (rigid or flexible), a printed design layer, and a transparent wear layer. The design layer is a high-resolution photograph of timber, stone, or other natural materials. The wear layer sits above it and determines durability.

Rigid core LVT (sometimes called SPC — stone plastic composite, or WPC — wood plastic composite) has become the dominant category in the premium end of the market. The core layer is dimensionally stable — it does not expand and contract significantly with temperature — which makes it appropriate over underfloor heating and in rooms with significant temperature variation.

Flexible LVT (the original form) requires a perfectly flat, smooth subfloor; any imperfection telegraphs through to the surface over time. It is less forgiving of subfloor movement and is now less commonly specified in high-quality residential work.

Where LVT is the right specification

Kitchens and utility rooms with underfloor heating: LVT has very low thermal resistance (typically 0.05–0.075 m²K/W), making it one of the most efficient floor coverings over underfloor heating systems. Natural stone is comparable; timber engineered boards are slightly higher; solid timber, carpet, and cork are not recommended over UFH. In a kitchen where the client wants a warm floor surface that heats quickly, LVT over hydronic UFH is a strong specification.

Secondary bathrooms and cloakrooms: LVT is fully waterproof (unlike timber and most natural stone, which require sealing and can be damaged by standing water). In an en suite or cloakroom where ease of maintenance is valued over high-end aesthetics, LVT is a practical and durable choice.

Rental and investment properties: LVT is highly resistant to scratching, scuffing, and moisture damage. In a rental property where the floor will be subject to heavy use and cannot be refinished between tenancies (unlike timber), LVT's durability is a genuine advantage.

Basement conversions: basements are often subject to residual moisture in the slab, even after tanking. Natural timber can be compromised by this. Rigid core LVT with its fully waterproof construction performs reliably in basement conditions.

Where LVT is not the right specification

Primary reception rooms and entrance halls in high-end properties: LVT reads and sounds different underfoot from natural stone or solid timber. In rooms where tactile quality matters to the client and where guests form their first impressions of the property, LVT is identifiable as a substitute. In a Belgravia townhouse or Kensington apartment, the principal floor surfaces should be natural stone or engineered timber.

Heritage properties with original floors: if original timber boards, encaustic tiles, or stone flags are present, they should be retained and restored wherever possible. Overlaying LVT over original flooring destroys value that cannot be replaced.

Outdoors: LVT is an interior product. It is not UV stable and is not appropriate for terraces, balconies, or external thresholds.

Specification: the wear layer

The single most important technical specification in LVT is the wear layer thickness. The wear layer is the transparent coating that protects the design layer from abrasion. Wear layer thickness is measured in millimetres (0.2mm to 0.7mm in residential products; up to 1.5mm in commercial).

For residential use in a main living area, specify a minimum 0.5mm wear layer. For secondary rooms (utility room, cloakroom), 0.3mm is sufficient. Products with 0.2mm wear layers are entry-level and will show wear in high-traffic areas within a few years.

Premium LVT manufacturers (Amtico, Karndean, Polyflor) publish wear layer specifications clearly. Be wary of products from less established brands where the wear layer specification is absent or cannot be confirmed.

Specification: installation method

LVT can be installed as:

Glue-down: each tile or plank is bonded to the subfloor with a pressure-sensitive adhesive. This is the most stable installation method and is required where the floor will be subject to significant heat variation (e.g. over high-output UFH). The subfloor must be flat to 3mm over a 2m straight edge — any high spots or hollows must be levelled with a latex compound first.

Click/floating: rigid core LVT with click profiles is installed as a floating floor, with an expansion gap around the perimeter. This is faster to install and easier to replace in sections. It is not appropriate over UFH where temperatures may exceed 27°C at the floor surface, as expansion can cause joint failures.

For quality residential work over underfloor heating, glue-down is the correct method.

Key brands

• —Amtico — the UK's premium LVT brand. Made in Coventry, extensive design range, available with bespoke cutting and pattern-laying services. Widely used in high-specification London residential work.
• —Karndean — strong competitor to Amtico, similar quality tier. Good design range, trade-focused distribution.
• —Polyflor — more commercially oriented but has residential ranges worth considering.
• —Moduleo — Belgian brand, good quality in the upper-mid tier.
• —Earthwerks — US-origin brand with strong commercial heritage, growing residential presence.

For a primary kitchen/utility floor in a quality London renovation, expect to pay £45–£85/m² for material (Amtico/Karndean specification) plus £25–£45/m² for installation and subfloor preparation. Total installed cost: approximately £70–£130/m².
