Engineered wood flooring gives London homeowners the look of solid timber with better resistance to moisture and temperature changes. It works well in period properties, new-build flats, and homes with underfloor heating. This guide covers what engineered wood flooring is, how to choose the right thickness and finish, pricing, and what to check before buying for a London home.
What Is Engineered Wood Flooring?
Engineered wood flooring is a multi-layer floor with a solid timber top layer bonded to plywood or high-density fibreboard underneath. The top layer, known as the wear layer, is usually between 2mm and 6mm of real hardwood such as oak, walnut, or ash.
The layered structure makes engineered flooring more stable than solid wood. Solid wood expands and contracts with humidity changes, which can cause gaps or warping in older London properties with less consistent heating. Engineered boards resist this movement because the cross-layered core balances the wood’s natural expansion.
Most engineered floors sold in the UK follow the EN 13489 standard for construction and dimensional stability. This standard sets requirements for the number of layers, core material, and wear layer thickness. Reputable UK flooring suppliers, including members of the Wood Flooring Association, manufacture products that meet this specification.
Engineered wood flooring suits:
- Victorian and Edwardian conversions common across London
- New-build apartments with concrete subfloors
- Homes with underfloor heating systems
- Ground-floor rooms prone to slight moisture
The multi-layer design also means engineered boards can be sanded and refinished, though fewer times than solid wood, depending on wear layer thickness.
How Thick Should Engineered Wood Flooring Be?
Engineered wood flooring is available in a range of thicknesses, commonly between 10mm and 20mm or more. The right specification depends on the subfloor, installation method, room use, and the manufacturer’s requirements.
Wear layer thickness is one of the main factors that affects refinishing life. A thicker wear layer generally allows more sanding cycles over the lifetime of the floor, though this depends on the product and how it’s fitted.
Indicative Refinishing Potential by Wear Layer Thickness
Wear Layer Thickness | Indicative Refinishing Potential |
2mm | 0–1 times |
3mm | 1–2 times |
4mm | 2–3 times |
6mm | 3–4 times |
Actual refinishing potential varies by product, sanding equipment, and technique, so these figures should be treated as a guide rather than a guarantee. Products at the thicker end of the range, around 18mm to 20mm, are commonly chosen for higher-traffic rooms or where a longer refinishing life is a priority.
Board thickness does not compensate for an uneven subfloor. The subfloor should be assessed and prepared to the manufacturer’s tolerances before installation, regardless of the board thickness chosen.
Many engineered wood flooring products are suitable for underfloor heating, with manufacturers commonly specifying a maximum floor-surface temperature. Always check the specific product’s technical instructions before installation.
How Much Does Engineered Wood Flooring Cost in London?
Engineered wood flooring in London typically costs between £35 and £90 per square metre for the material alone. Premium wide-plank or brushed and oiled finishes can exceed £120 per square metre.
Installation adds a separate cost, usually between £20 and £40 per square metre depending on subfloor preparation and fitting method. A typical London living room of around 20 square metres costs between £1,100 and £2,600 in total, including materials and fitting.
Price is affected by:
- Wood species, with oak generally cheaper than walnut
- Wear layer thickness
- Board width and finish type
- Subfloor condition and levelling work required
- Whether underfloor heating compatibility is needed
Getting a written quote broken down by material cost and labour cost makes it easier to compare suppliers accurately before booking installation.
What Finish Options Are Available for Engineered Wood Flooring?
Engineered wood flooring comes in three main finish types: lacquered, oiled, and brushed and oiled. Each finish affects durability, maintenance, and appearance differently.
- Lacquered finish: A protective sealed surface that resists spills and is easier to clean. Best for busy households and rental properties.
- Oiled finish: Penetrates the wood for a more natural matt look. Requires periodic re-oiling, roughly every 12 to 18 months in high-traffic areas.
- Brushed and oiled finish: Combines a textured surface with an oiled coating, showing the wood grain more clearly.
Lacquered floors generally need less maintenance over the first few years. Oiled floors are easier to spot-repair since individual boards can be re-oiled without refinishing the whole floor. London homeowners choosing a finish for hallways or kitchens often prioritise the lacquered option for its wipe-clean surface.
Is Engineered Wood Flooring Suitable for London’s Climate?
Engineered wood flooring performs well in London’s climate because its layered core resists the moisture and temperature shifts common in the city’s housing stock. London’s humidity varies considerably throughout the year and across the day, and these changes can affect timber flooring, which is why indoor environmental conditions and moisture levels should be considered before installation.
Solid wood floors are more prone to gapping and cupping when indoor conditions fluctuate, particularly in period properties with suspended timber floors and less consistent insulation. Engineered flooring’s cross-layered structure limits this movement, making it a more predictable choice for London’s older housing.
Ground-floor rooms and basement conversions, common in London terraced housing, also benefit from engineered flooring’s better resistance to minor moisture compared with solid timber. Concrete subfloors should be moisture-tested before installation. Where required by the subfloor condition and flooring system, an appropriate damp-proof membrane or moisture barrier may be necessary.
How Do You Install Engineered Wood Flooring?
Engineered wood flooring can be installed using three main methods: floating, glue-down, or secret nailing. The right method depends on the subfloor type and whether underfloor heating is present.
- Assess the subfloor for moisture and levelness
- Moisture-test concrete subfloors and fit a damp-proof membrane where the subfloor condition or flooring system requires it
- Choose floating, glue-down, or nailed installation
- Allow the flooring to acclimatise according to the manufacturer’s installation instructions and the conditions of the property
- Lay an underlay if using the floating method
- Fit the boards following the manufacturer’s expansion gap guidance
- Finish with skirting or scotia trim
Glue-down installation is generally recommended for rooms with underfloor heating, since it improves heat transfer compared with a floating floor. Floating installation is faster and works well over most flat subfloors without underfloor heating.
Choosing the right engineered wood flooring depends on your subfloor, heating system, and how the room gets used day to day. Speak to the Trade Flooring team for advice on the best engineered wood flooring for your London home and a free quote.
Frequently Asked Questions
Yes, engineered wood flooring can be installed over concrete subfloors, provided the subfloor is moisture-tested and, where required, fitted with an appropriate damp-proof membrane.
A well-maintained engineered wood floor with a 4mm wear layer can last 25 to 30 years, including one or two refinishing cycles.
Many engineered wood flooring products are compatible with underfloor heating, though the manufacturer’s maximum floor-surface temperature rating should always be checked before installation.
Engineered flooring has a layered core with a real wood top layer, while solid wood flooring is made from a single piece of timber throughout.
