LVT flooring is one of the easiest types to install — but even a small mistake can ruin the final look. Here’s how to get it right the first time.
"We didn’t check the subfloor level properly and ended up with a click vinyl floor that creaked and lifted at the edges. Had to rip it all up after a month."— Dave H., Leeds homeowner
Introduction
Luxury Vinyl Tile (LVT) flooring has exploded in popularity across the UK. It’s stylish, durable, waterproof, and great for DIYers thanks to its easy click-and-lock system. But as with any home project, a few common mistakes can turn a dream floor into a disaster.
In this guide, we’ll walk you through the top 10 mistakes people make when installing LVT flooring—and how to avoid them. Whether you're a first-time installer or just need a refresher, these tips can save you time, money, and frustration.
Mistake 1: Skipping Subfloor Preparation
Why it’s a problem: Uneven or damp subfloors are the #1 cause of flooring failure. Click systems won’t lock properly, and gaps or bumps will appear.
How to avoid it:
Use a spirit level to check for dips and high spots
Apply a self-levelling compound if needed
Ensure the floor is completely dry
Use a moisture meter, especially on concrete
External Tip: Karndean recommends a maximum moisture level of 75% RH for subfloors
Mistake 2: Not Acclimating the Flooring
Why it matters: LVT expands and contracts with temperature. Skipping this step can lead to warping or lifting.
How to avoid it:
Leave the unopened boxes in the room for at least 48 hours
Keep the room at normal living temperature (18–21°C)
Mistake 3: Using the Wrong Underlay (or None at All)
Why it matters: Underlay provides support, reduces noise, and adds insulation. The wrong one can cause instability or void your warranty.
How to avoid it:
Use an LVT-compatible underlay (not carpet underlay)
Some click systems have built-in underlay—check your product specs
Use moisture barriers if installing over concrete

Mistake 4: Not Leaving Expansion Gaps
Why it’s important: LVT needs room to expand with temperature changes. Without a gap, it can buckle.
How to avoid it:
Leave a 5–10 mm expansion gap around the edges
Use spacers during installation
Cover gaps later with skirting boards or scotia trim
Mistake 5: Poor Layout Planning
Why it’s a big issue: If you don’t plan the plank layout, you might end up with tiny slivers at the edges or awkward transitions at doorways.
How to avoid it:
Dry lay the first few rows to see how they line up
Measure the room width and divide by plank width to avoid small cuts
Stagger planks for a natural look and stronger joints
Mistake 6: Cutting Without Proper Tools
Why it matters: Bad cuts create gaps and chipped edges that weaken the locking system.
How to avoid it:
Use a vinyl tile cutter, sharp utility knife, or fine-tooth saw
Always cut on a flat surface
Score and snap for straight lines; saw for curves or notches
Mistake 7: Forgetting to Check Every Click
Why it happens: In a hurry, you may miss clicks that haven’t locked. Over time, this can cause boards to separate.
How to avoid it:
Run your hand along each seam as you go
Gently tap planks into place with a rubber mallet if needed
Mistake 8: Installing in the Wrong Order
Why this matters: Planks should be installed left to right and top to bottom of the room, with light direction in mind.
How to avoid it:
Start in the corner of the longest wall
Lay planks parallel to the main light source for the best appearance
Mistake 9: Not Reading the Manufacturer’s Instructions
Why it’s risky: Every product has unique installation rules. Ignoring them could void your warranty.
How to avoid it:
Always download and review the official installation guide
Check for specific underlay, expansion, or cleaning requirements
Mistake 10: Rushing the Job
Why it’s tempting: Click vinyl seems quick and easy, but rushing leads to errors.
How to avoid it:
Give yourself time
Work in small sections
Double-check alignment and joins
Take breaks to maintain focus
FAQ: Common LVT Installation Questions
Q: Can I install LVT in the bathroom?A: Yes—just ensure the subfloor is dry and sealed. Use silicone sealant at edges.
Q: Do I need to glue down click LVT?A: No. Click LVT is designed to float. Glue-down vinyl is a different product.
Q: How long after installation can I walk on LVT?A: Immediately if it's click flooring. For glue-down, wait at least 24 hours.
Q: Will furniture damage LVT?A: It can if you don’t use felt pads. Avoid dragging heavy items.
Q: What temperature should the room be during installation?A: Keep it between 18–21°C. Avoid cold or humid environments.
Conclusion
Installing LVT flooring is absolutely doable—but like any project, the success is in the details. From subfloor prep to planning your layout and taking your time, every step matters.
By avoiding these 10 common mistakes, you can enjoy a stunning, long-lasting floor that looks professional and feels great underfoot.
