Laminate Floor Installation Guide

A professional installation is about more than just clicking planks together; it ensures the longevity of the product through meticulous subfloor preparation and correct expansion allowances. This guide outlines what to expect during the process, the current market rates in the UK, and how to ensure a high-quality finish that lasts for decades.

What Does the Work Involve?

• Site Survey and Acclimation: The fitter inspects the subfloor for moisture and levelness. Laminate planks must be stored in the room for 48 hours prior to fitting to acclimate to the local temperature and humidity.
• Subfloor Preparation: This includes removing old floor coverings, sanding down high spots, or applying a self-levelling compound to uneven concrete. The floor must be clean, dry, and flat within a 3mm tolerance.
• Underlay Installation: Laying the correct underlay is vital for sound insulation, thermal properties, and moisture protection. Fitters will tape seams to create a continuous vapour barrier.
• Precision Cutting and Laying: Planks are laid with a staggered joint pattern for structural integrity. Fitters use specialist saws to undercut door architraves, allowing the flooring to slide underneath for a professional look.
• Expansion Gaps: A 10mm to 12mm gap is left around the entire perimeter to allow the floor to "float" as it expands and contracts with the seasons.
• Finishing Touches: Installation of "Scotia" beading or new skirting boards to cover expansion gaps, along with door thresholds (T-bars) to transition between rooms.

Typical Costs

The cost of laminate installation varies based on the quality of the material and the complexity of the room shape. Prices below include VAT and represent 2025/26 UK averages.

Price Factors: Total costs are influenced by the "wastage" factor (usually 10%), the need for furniture removal, and whether you choose to replace skirting boards entirely rather than using beading.

Professional fitters often have a minimum day rate of £200–£300, even for very small rooms, to cover their travel and setup time.

How Long Does It Take?

• Standard Bedroom (12m²): 3–5 hours including underlay and beading.
• Open Plan Living/Dining Area (30m²): 1 full day.
• Hallway with multiple doorways: 4–6 hours (slower due to intricate cutting around frames).
• Whole House (3-bed semi): 3–4 days depending on subfloor condition and furniture.

DIY or Professional?

While laminate is marketed as a DIY-friendly "click" product, the difference between a DIY job and a professional finish is usually found at the edges. Amateurs often struggle with undercutting door frames and maintaining consistent expansion gaps, which can lead to the floor "peaking" or buckling within six months.

If you are laying floor in a flat or apartment, professional installation is highly recommended to ensure compliance with acoustic regulations. A pro will also have the heavy-duty cutters required for thicker 12mm boards, which can quickly blunt standard DIY tools.

Choosing the Right Tradesperson

• Check Specialisms: Look for a floor layer or a carpenter. General handymen may be cheaper but may lack the specialist tools for clean architrave cuts.
• Insurance: Ensure they have Public Liability insurance to cover any accidental damage to your property or subfloor.
• Portfolio: Ask to see photos of finished "perimeters"—the quality of the beading and door transitions is the true mark of a skilled fitter.

Questions to ask your fitter:

• Do you include the disposal of old flooring and offcuts in your quote?
• Will you check the moisture levels of the subfloor before starting?
• Do you offer a guarantee on the installation (separate from the product warranty)?
• Will you need to trim the bottom of the doors, and is this included in the price?

UK Regulations

• Building Regulations Part E (Resistance to Sound): If you live in a flat, you are legally required to ensure the flooring does not significantly increase noise transfer to the neighbours below. You may need high-decibel (dB) rated underlay.
• Building Regulations Part C (Moisture): New build concrete floors must be fully cured and tested for moisture. An integrated damp-proof membrane (DPM) in the underlay is standard practice.
• Product Standards: Ensure your laminate is CE or UKCA marked and carries an AC (Abrasion Class) rating of at least AC3 for domestic use.

Common Problems

• Floor Bouncing: Usually caused by an uneven subfloor. If the "humps and hollows" aren't fixed first, the click-joints will eventually snap under foot traffic.
• Buckling/Peaking: This happens when no expansion gap was left. As the boards naturally expand, they hit the wall and have nowhere to go but up.
• Gapping: If the boards weren't acclimated to the room's temperature, they may shrink after installation, leaving unsightly gaps between planks.
• Soft Spots: Using an underlay that is too thick or "spongy" can cause the floor to feel unstable and put stress on the locking mechanism.

Frequently Asked Questions

Can I lay laminate over existing carpet?

No. Carpet is too soft and will cause the laminate joints to flex and eventually break. Carpet must be removed, and the subfloor cleaned before installation.

Is laminate flooring waterproof?

Most standard laminate is water-resistant but not waterproof. However, many modern ranges (often labelled "Aqua") are designed for bathrooms and kitchens with sealed joints that can withstand standing water for 24–72 hours.

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

Yes. Laminate is made of wood fibres which expand and contract. Skipping acclimation is the leading cause of floor failure and will usually void your manufacturer's warranty.

What is the difference between Scotia and Skirting?

Scotia is a small decorative trim used to cover the expansion gap against existing skirting boards. If you want a cleaner look, you can remove the skirting boards, fit the floor, and then install new skirting on top.

Can laminate be used with underfloor heating?

Yes, but you must check the manufacturer's specifications. You will also need a specific low-tog underlay that allows heat to pass through efficiently without damaging the boards.

How do I clean my new laminate floor?

Use a microfiber mop and a specialist laminate cleaner. Never use a steam mop or soaking wet mop, as excessive moisture can seep into the joints and cause the core to swell.
