Which Is Right for Your Home in 2026?
The most fundamental decision in any wood flooring installation project, before you even think about colour, species, or plank width, is whether to specify engineered or solid wood. Both are genuinely beautiful. Both are made from real wood. But they behave very differently in service, they are installed differently, and the cost difference between comparable specifications is more significant than many people realise.
This is not a question of which is better in absolute terms. It is a question of which is right for your specific property, room, subfloor, and circumstances. A solid oak floor in the first-floor bedroom of a traditional London Victorian terrace, with its suspended timber subfloor and relatively stable temperature conditions, could last 100 years and be sanded and refinished multiple times. The same solid oak floor installed in a ground floor open-plan kitchen-diner over a concrete subfloor with underfloor heating could develop gapping and movement within a year, requiring lifting and replacement. The wood is not at fault - the installation decision was wrong.
This guide helps you make an informed choice. To discuss your specific project with our team, visit our wood flooring installation page or arrange a free survey.
The Structural Difference Between Engineered and Solid Wood Flooring
Understanding the construction of each product is the foundation for understanding how they behave differently in use.
Solid wood flooring is machined from a single piece of timber, typically between 18mm and 22mm thick. Because each plank is one solid piece of wood throughout its depth, the material is subject to the natural expansion and contraction of wood in response to changes in temperature and humidity. In a centrally heated London home that fluctuates between winter dryness (low humidity, boards contract) and summer humidity (boards expand), solid wood can move measurably with the seasons. This movement is entirely normal and manageable with correct installation, appropriate expansion gaps, and stable indoor conditions.
Engineered wood flooring is manufactured from multiple layers of wood bonded together under high pressure, with the grain directions of adjacent layers running at 90 degrees to each other. This cross-laminated structure fundamentally counteracts the natural tendency of wood to expand and contract in one direction. The result is a product that is significantly more dimensionally stable than solid wood under varying temperature and humidity conditions. On top of this stable plywood or HDF core sits a real hardwood veneer - typically between 2mm and 6mm thick - which provides the aesthetic surface of the floor. Thicker veneers allow more refinishing cycles and generally indicate a more premium product.
Which Type of Wood Flooring Installation Is Right for Each Room?
The room-by-room suitability of solid versus engineered wood flooring is determined primarily by moisture exposure, temperature stability, and the subfloor type.
Solid wood flooring performs best in rooms with stable temperature and humidity conditions, away from direct moisture exposure. Upper-floor bedrooms and living rooms without underfloor heating, where conditions are relatively stable year-round, are the ideal application for solid wood. Victorian-era timber subfloors, which breathe and have natural flexibility, are compatible with secret-nailed solid wood installation.
Solid wood is not suitable for installation over underfloor heating systems of any type. The heat cycles cause the wood to expand and contract repeatedly in ways that solid wood cannot accommodate without gapping, cupping, or surface cracking. It is also not recommended for ground floor rooms over concrete slabs without exceptional moisture management, as rising ground moisture over time will cause even well-protected solid wood to fail.
Engineered wood flooring is the more versatile of the two products. It is suitable for installation over underfloor heating (at maximum surface temperatures of 27 degrees Celsius or as specified by the manufacturer), over ground floor concrete subfloors with appropriate moisture protection, and for open-plan spaces that encompass both a kitchen and a living area. In London properties, where ground floor open-plan living has become the dominant design format, engineered wood is almost always the correct wood flooring specification.

Cost Comparison: Engineered vs Solid Wood Flooring Installation in London 2026
Material costs in 2026 (London market prices):
Engineered wood (budget, 2 to 3mm veneer, standard format): £20 to £35 per square metre
Engineered wood (mid-range, 3 to 4mm veneer, quality oak): £35 to £60 per square metre
Engineered wood (premium, 5 to 6mm veneer, wide plank, specialist finish): £60 to £100 per square metre
Solid oak (standard format, 18mm): £30 to £50 per square metre
Solid oak (wider boards, better grade, brushed or oiled finish): £50 to £80 per square metre
Solid wood (premium species, wide plank, reclaimed or heritage): £80 to £160 per square metre
Installation costs in London are broadly similar for both types at the standard level - typically £15 to £25 per square metre for straight plank laying. Parquet or herringbone patterns add £15 to £25 per square metre to the labour cost due to the additional complexity.
One important cost consideration is the long-term maintenance picture. Solid wood's ability to be sanded and refinished multiple times - potentially every 10 to 15 years for a heavily trafficked floor - means that the floor may be maintained in excellent condition indefinitely.
Engineered wood with a thicker veneer can be refinished two to three times; after that, the floor must be replaced. The long-term cost of ownership therefore often favours solid wood for homeowners with a multi-decade view.
Key Differences: A Direct Comparison for London Homeowners
Moisture tolerance - engineered wood is significantly more tolerant of moisture than solid wood. Ground floor rooms and kitchens (where solid wood is not suitable) can use engineered wood with appropriate subfloor preparation
Underfloor heating compatibility - engineered wood is compatible with underfloor heating; solid wood is not recommended
Refinishing - solid wood can be sanded and refinished many times; engineered wood can be refinished two to three times depending on veneer thickness
Dimensional stability - engineered wood moves less with seasonal humidity and temperature changes than solid wood
Authentic character - solid wood develops a unique patina and character over decades that engineered wood veneers cannot fully replicate
Cost - at comparable quality levels, engineered and solid wood are often similarly priced in materials; installation costs are broadly equivalent

Frequently Asked Questions: Engineered vs Solid Wood Flooring
Q: Which lasts longer, engineered or solid wood flooring?
A: Solid wood can be sanded and refinished many more times than engineered wood, giving it a longer theoretical lifespan. However, engineered wood with a thick 4mm or 6mm veneer can last 20 to 30 years or more with proper maintenance and can be refinished two to three times.
Q: Can engineered wood flooring be used with underfloor heating?
A: Yes. Engineered wood is the recommended specification for rooms with underfloor heating because its cross-laminated core is more dimensionally stable than solid wood under heat cycles. Always confirm the specific product is rated for your heating system.
Q: Is solid wood flooring worth the extra cost?
A: For long-term homeowners who want a floor they can refinish repeatedly over many decades, solid wood is a sound investment. For properties with underfloor heating, concrete subfloors, or where the budget is a constraint, engineered wood typically offers better practical value.
Q: Can I mix engineered and solid wood in different rooms?
A: Yes, provided you select products from the same wood species and with a closely matched finish. Many manufacturers produce both solid and engineered versions of the same product to allow mixed use across a property.
Q: Does wood flooring installation add value to a London property?
A: Yes. Quality wood flooring is consistently cited by estate agents and property developers as one of the flooring types most likely to add demonstrable value to a London property, particularly in period homes where wood floors are historically appropriate.
