Warm, quiet and one of the few genuinely renewable floors you can buy, cork is having a real moment. Here’s an honest look at what it costs, where it works, where it doesn’t, and how to get it fitted so it lasts.

What is cork flooring?

Cork comes from the bark of the cork oak tree. The bark is harvested by hand every nine years or so without felling the tree, which keeps growing and re-grows its bark — which is why cork is considered one of the most sustainable flooring materials available. That bark is ground, compressed and baked into tiles or planks. The same air-filled cell structure that makes a wine cork springy is what makes a cork floor warm, quiet and soft underfoot.

The two types of cork floor

Glue-down cork tiles

Thin tiles bonded directly to a prepared subfloor with adhesive. This is the more hard-wearing, water-resistant option and the better choice for kitchens and busy areas. It needs a flat, sound subfloor and is usually sealed after fitting, so it’s the more skilled installation of the two.

Floating click cork

Planks with a cork core and a click-locking edge that float over a thin underlay — nothing is glued down. They often have a printed wood or stone-effect top layer with a factory finish. Quicker to fit, easy to lift later, and forgiving of minor subfloor imperfections.

The pros of cork

• Warm underfoot. Cork is a natural insulator, so it never feels cold the way tile or vinyl can.
• Quiet and soft. Millions of air cells absorb sound and give underfoot — great for bedrooms, offices and flats.
• Comfortable to stand on. That cushioning reduces foot and joint fatigue, which is why cork is popular in kitchens.
• Naturally hypoallergenic. Cork contains suberin, a waxy substance that resists mould, mildew and pests.
• Genuinely sustainable. Harvested without harming the tree, and biodegradable at the end of its life.

The cons (the honest bit)

• It’s soft. Heavy furniture, sharp pet claws or trapped grit can dent or scratch it. Felt pads and doormats go a long way.
• It can fade in strong sun. Direct sunlight will gradually lighten cork, so south-facing rooms with big windows need a UV-resistant finish or some shading.
• It needs sealing for damp areas. Cork can handle kitchens and even bathrooms, but only when properly sealed — and it should be re-sealed every 2–4 years in those rooms.

How much does cork flooring cost in the UK?

As a rough 2026 guide:

Thicker tiles and unsealed cork (which then needs sealing) shift the price, as does the state of your subfloor. The only way to know your real number is a measured quote.

Cork and underfloor heating

Good news: most cork is compatible with underfloor heating. The catch is that cork insulates, so there’s a maximum thickness (and a maximum tog when you add underlay) beyond which the heat struggles to come through efficiently. Stick to the manufacturer’s stated limits and keep the floor temperature within their range, and cork over UFH is warm and comfortable.

Which rooms suit cork?

• Living rooms, bedrooms, offices, hallways: ideal — cork is at its best here.
• Kitchens: a great fit, especially sealed glue-down cork.
• Bathrooms and utility: possible with properly sealed cork and regular re-sealing — get advice first.
• Conservatories / very bright south-facing rooms: watch for fading; choose a UV-resistant finish.

Looking after a cork floor

Sweep or vacuum regularly to keep grit off the surface, and clean with a slightly damp (never soaking) mop. Use felt pads under furniture legs, lift rather than drag heavy items, and put mats at exterior doors. In kitchens, bathrooms and other damp rooms, re-seal every couple of years. Treated this way, a cork floor will easily last decades.
