Laminate Flooring Installation Guide

A professional installation is about more than just clicking planks together; it ensures the subfloor is perfectly prepared and the necessary expansion gaps are maintained. This guide covers everything you need to know about the process, costs, and timelines for a high-quality finish in your home.

What Does the Work Involve?

• Site Survey: Measuring the room accurately and checking subfloor moisture levels, especially in ground-floor rooms.
• Acclimatisation: Storing the laminate planks in the target room for at least 48 hours to adjust to the local temperature and humidity.
• Subfloor Preparation: Removing old floor coverings and ensuring the surface is clean, dry, and level (within 2-3mm over a 2m span).
• Underlay Installation: Laying the correct underlay for sound reduction, thermal insulation, or moisture protection.
• Plank Fitting: Laying the laminate with staggered joints and maintaining a 10mm expansion gap around the perimeter.
• Finishing Touches: Undercutting door frames for a seamless look and installing scotia beading or skirting boards to cover expansion gaps.

Typical Costs

Prices include VAT and are based on standard 2025 UK market rates. Total costs are heavily influenced by the "wastage" factor; always order 10% more material than the room's square footage to account for cuts.

How Long Does It Take?

• Small Hallway or Cloakroom: 3–5 hours (including prep and trims).
• Standard Living Room (approx. 20m²): 1 full day for a single installer.
• Large Open-Plan Ground Floor: 2–3 days, depending on the number of door thresholds and complex cuts.
• Acclimatisation (Mandatory): 48 hours prior to the start of work.

DIY or Professional?

While laminate is marketed as a DIY-friendly "click" product, the finish is only as good as the subfloor preparation. Professional installers have the specialist tools required to undercut door architraves, ensuring the floor sits under the frame rather than being cut awkwardly around it.

If you are installing over a concrete subfloor or in a flat where sound insulation is a legal requirement, hiring a professional is highly recommended to ensure compliance with UK building standards.

Choosing the Right Tradesperson

• Look for fitters who are members of the National Institute of Carpet and Floorlayers (NICF) or have manufacturer-specific accreditation.
• Check that the quote includes the removal and disposal of your old flooring and any offcuts.
• Red Flag: A fitter who wants to start immediately without allowing the boards to acclimatise in your home first.
• Question to ask: "How do you handle the expansion gaps around radiator pipes and door frames?"
• Question to ask: "Is the subfloor levelling included in the initial quote, or is that an extra cost after inspection?"

UK Regulations

• Building Regulations Part E: Relevant for those living in flats or apartments; you must ensure the underlay meets specific decibel (dB) reduction ratings for impact noise.
• Waste Disposal: Ensure your tradesperson has a valid waste carrier licence if they are taking old carpets or laminate away.
• Product Standards: Ensure the laminate has an AC (Abrasion Class) rating suitable for the room (AC3 for bedrooms, AC4 or AC5 for busy hallways).

Common Problems

• Peaking: When boards push against each other and rise at the joints; usually caused by a lack of expansion gaps at the walls.
• Bouncing/Springiness: Occurs when the subfloor is uneven, leaving voids beneath the planks that cause them to flex when walked on.
• Gapping: Boards separating over time, often because they weren't acclimatised or the room is subject to extreme temperature swings.
• Moisture Damage: Swelling at the edges caused by wet-mopping or spills entering the joints of non-water-resistant laminate.

Frequently Asked Questions

Can laminate be installed in bathrooms or kitchens?

Only if you choose a specific "water-resistant" or "hydro" range. Standard laminate has a wood-fibre core that will swell and blow if exposed to standing water or high humidity.

Do I really need to leave the flooring in the room for 48 hours?

Yes. Laminate expands and contracts with heat and humidity. If you fit it "cold" straight from a warehouse, it may expand once installed, causing the floor to buckle or peak.

Can I lay new laminate over old carpet?

No. Carpet is too soft and will cause the laminate joints to flex and eventually snap. All carpet and underlay must be removed to provide a solid, level base.

Is laminate flooring compatible with underfloor heating?

Most modern laminates are compatible, but you must check the manufacturer's "TOG" rating. You will also need a specific low-tog underlay designed to allow heat transfer.

What is the difference between Scotia and Skirting?

Skirting is the board at the base of the wall. Scotia is a small concave trim used to cover the expansion gap if you don't want to remove your existing skirting boards.
