Click LVT flooring, also known as SPC (Stone Polymer Composite) rigid core vinyl, uses a precision click-lock system that allows the floor to float over the subfloor without adhesive. This type of Luxury Vinyl installation combines the durability of rigid core construction with the simplicity of a floating click system.
When installed correctly, SPC click flooring provides a stable, durable surface suitable for modern UK homes. SPC click flooring is dimensionally stable compared to traditional laminate, but correct expansion allowances remain essential to ensure long-term performance.
This guide explains each stage of installation clearly and practically — from preparing the room and planning the layout to engaging the click system and finishing the perimeter. It is suitable for confident DIY installers and professionals alike, with a focus on correct floating installation, accurate joint engagement, and maintaining the movement tolerances required for reliable performance.
By following this guide, you’ll understand how the system works, how to prepare the base properly, and how to install the floor efficiently while allowing the controlled movement that SPC flooring requires.
This guide applies specifically to standard straight plank SPC click flooring installed as a floating floor.

2. Room Conditions & Planning Ahead
Taking a few minutes to prepare the room and plan your layout can save time once you start laying the floor and help everything run smoothly.
Room Conditions
Click LVT (SPC) flooring should be installed in a dry, enclosed space with normal living conditions. Aim to keep the room at a comfortable, consistent temperature, ideally between 18°C and 27°C, both before and during installation. Avoid installing the floor in areas where temperatures may fluctuate significantly or where the room is not yet fully enclosed.
Subfloor Overview
Click LVT (SPC) flooring can be installed over most common subfloors, including concrete and wooden subfloors, provided they are stable and suitable for a floating floor. Any existing floor coverings should be removed before installation, leaving a solid base for the new floor to sit on.
Further guidance on preparing the subfloor is covered later in this guide.
Measuring the Room
Measure the length and width of the room and multiply these figures to calculate the total square metres required. Measure at several points, especially in older or irregularly shaped rooms, and use the largest measurement to ensure accurate coverage.
Ordering the Correct Quantity
When ordering your Click LVT (SPC) flooring, allow an additional 10–15% for cutting, waste, and natural layout variation. This extra allowance helps ensure you can complete the installation without interruption, particularly in rooms with multiple doorways or detailed cuts.
Important: It is the installer’s responsibility to inspect the flooring prior to installation. Installation of the product confirms that the material has been checked and accepted.
3. Acclimatising Click LVT (SPC) Flooring
Before installation, allow your Click LVT (SPC) flooring to acclimatise in the room where it will be fitted for 24–48 hours. This helps the planks adjust to the ambient conditions and supports a smooth installation.
Keep the packs flat, unopened, and stored on a level surface, away from direct heat sources or sunlight. The room should be at normal living conditions, with a stable temperature and no extreme changes during this period.
If the room has underfloor heating, ensure the system is switched off during acclimatisation and installation. Full guidance on underfloor heating use is provided later in this guide.
4. Preparing the Subfloor
Click LVT (SPC) flooring performs best when installed over a clean, dry, flat, and stable base. Taking the time to prepare the subfloor properly will help the click system engage correctly and ensure a consistent finish across the floor.
Clean & Dry
The subfloor should be free from dust, debris, paint, old adhesive residue, or loose material. Sweep and vacuum thoroughly before installation. Any spills or damp patches should be fully dry before the flooring is laid.
Flatness Tolerance
The subfloor should be level to within 3mm over a 2-metre straight edge. Localised high spots or dips beyond this tolerance should be corrected before installation. A flat surface helps prevent joint stress and ensures the planks sit evenly once clicked together.
Moisture Awareness
Concrete subfloors should be dry and suitable for a floating floor installation. Where moisture is present or suspected, a suitable damp-proof membrane should be used in accordance with standard flooring practice. Wooden subfloors should be sound, securely fixed, and free from movement.
Existing Floor Removal
Remove any existing floor coverings, trims, or fixings before installation. Ensure nails or screws are set below the surface so they do not interfere with the underlay or plank connections.
Built-in Underlay
Click LVT (SPC) flooring is supplied with a built-in underlay, designed to provide comfort and acoustic performance. No additional underlay should be installed unless specifically approved for use with the product.
Adding an extra underlay can cause bounce, joint stress, and locking issues, so only use one if your specific product instructions explicitly allow it.
This section covers the key checks, but if you need a clearer step-by-step on levelling, moisture control, and DPM options by subfloor type, refer to our Subfloor Preparation Guide before you start.
5. Planning the Layout
Spending a little time planning the layout before installation begins will make the process easier and help achieve a balanced, professional-looking finish.
Plank Direction
In most rooms, Click LVT (SPC) planks are best laid along the longest wall or in the same direction as the main light source. This helps the floor look more natural and can make the space feel longer and more open. In square rooms, consider the room entrance and how the floor will be viewed as you walk in.
Light Flow & Room Orientation
Natural light can highlight joints and surface detail. Running planks parallel to incoming light often gives the most even appearance, particularly in larger or brighter rooms.
Staggering the Joints
To create a strong and visually balanced floor, stagger the short-end joints between rows. A minimum stagger of 300–400mm is recommended. Avoid lining up joints in adjacent rows, as this can weaken the floor and affect the overall appearance.
The offcut from the end of one row can usually be used to start the next row, provided it meets the minimum stagger length. This helps maintain a consistent pattern and reduces waste.
Final Row Width Planning
Before you start laying, calculate the width of the final row. If the final row would be very narrow, trim the first row slightly so the last row finishes at a practical width, ideally no less than 50–60mm. This small adjustment early on helps maintain a clean, consistent look across the room.
6. Installation Method: Floating Click System
This guide covers Click LVT (SPC) flooring installed using a click-lock floating system.
With this method, the planks lock together to form a single floating floor that sits over the subfloor without adhesive or mechanical fixings. The floor is not fixed to the subfloor, allowing it to move slightly as a complete surface in response to normal temperature changes.
No glue-down or loose-lay installation methods are covered in this guide. All instructions that follow relate specifically to SPC click-lock floating installation.
7. Installing Your Click LVT (SPC) Floor – Step by Step
This section covers the installation of Click LVT (SPC) flooring using a floating click-lock system. Work methodically, row by row, and take time to ensure each connection is fully engaged before moving on.
8. Expansion & Movement Rules
Click LVT (SPC) flooring is installed as a floating floor and must be able to move as a single surface.
The rules below define how expansion gaps and movement control must be managed to ensure long-term performance.
Perimeter Gaps
Leave a consistent 6mm expansion gap around the entire perimeter of the room. This gap should be maintained between the flooring and all walls, skirting boards, and vertical surfaces. Use spacers during installation and remove them once the floor is complete.
Fixed Objects
A 6mm expansion gap should also be left around all fixed objects, including:
- Kitchen units and fitted furniture
- Radiator pipes
- Structural columns
- Door frames and thresholds
The flooring should never be tight against any fixed element.
Kitchen Cabinets & Islands
Click LVT (SPC) flooring should not be installed underneath heavy kitchen cabinets or islands. These items should be fitted first, with the flooring installed around them and the correct expansion gap maintained.
Kitchen units and islands typically use plinths, which can be used to neatly cover the flooring edge while still allowing the floor to move freely.
Installing heavy, fixed furniture on top of a floating floor can restrict movement and may lead to stress or distortion over time.
Doorways
Expansion gaps must be allowed at doorways and openings between rooms. Where the same Click LVT (SPC) flooring is installed continuously between adjoining rooms, the floor can often run through without a transition, provided it is free to move as a single floating surface.
Threshold or transition profiles should be used where required to maintain expansion gaps, accommodate movement, or where different flooring types meet.
Large Rooms
Click LVT (SPC) flooring can usually be installed as one continuous floor across multiple rooms or long runs, provided expansion gaps are maintained and the floor is not restricted by fixed objects.
Where the floor extends beyond approximately 10 metres in one direction, exceeds around 100m², or movement may be restricted, a transition profile can be used to divide the floor into smaller sections, each with its own expansion allowance.
Transitions
Use appropriate transition profiles where the SPC flooring meets:
- Other flooring types
- Separate rooms
- Changes in direction
Transitions help accommodate movement while creating a clean, finished appearance.
9. Underfloor Heating Compatibility
Click LVT (SPC) flooring works very well with water-based underfloor heating systems when installed and operated correctly. These systems provide slow, even heat, which suits floating SPC floors and helps maintain consistent performance across the surface.
Water-Based Underfloor Heating
Water-based (hydronic) underfloor heating systems are the preferred option for Click LVT (SPC) flooring. When installed within the subfloor and controlled accurately, they offer stable heat distribution and reliable day-to-day use.
The maximum finished floor surface temperature should not exceed 27°C. To allow conditions to stabilise, the heating system should be switched off at least 48 hours before installation. After installation, the system can be switched back on gradually, increasing the temperature by no more than 5°C per day until normal operating levels are reached.
Electric Underfloor Heating
Some electric underfloor heating systems may be suitable for use beneath Click LVT (SPC) flooring when they are fully embedded within the subfloor and provide accurate temperature control. Because electric systems can widely vary in design, quality and performance, compatibility should be confirmed with the underfloor heating manufacturer and the flooring supplier before installation.
This approach helps ensure temperatures remain consistent across the floor surface and supports long-term performance.
Why Temperature Control Matters
Maintaining stable temperatures allows the flooring system to expand and contract evenly as a single floating surface. This helps keep joints aligned, prevents localised stress, and ensures the floor continues to look and perform as intended.
For more detailed guidance on system setup, commissioning, and temperature control, see our dedicated guide: LVT Click (SPC) Flooring & Underfloor Heating Guide.
10. Finishing Details
Once the main floor is installed, a few finishing touches will help achieve a clean, professional result and allow the floor to perform as intended.
Fitting Around Pipes
Where pipes pass through the floor, mark their positions carefully on the plank. Drill a hole slightly larger than the pipe to allow for expansion. The plank can then be cut to the hole and fitted into place.
If needed, a small offcut can be glued back in position behind the pipe to create a neat finish. Pipe covers can also be used to conceal the expansion gap.
Door Frames
For a tidy result at doorways, the bottom of the door frame or architrave can be undercut so the flooring slides neatly underneath. This allows the floor to move freely while avoiding visible gaps.
When working around door frames, take your time and test-fit planks before locking them fully into place.
Transitions
Transition profiles are used where the SPC flooring meets other floor types, changes direction, or passes through doorways where an expansion gap needs to be covered. The profile should sit above the floor without restricting movement.
Skirting Boards & Trims
Skirting boards, beading, or edge trims are used to cover the expansion gap around the perimeter of the room. These should be fixed to the wall, not the floor, allowing the SPC flooring to move freely underneath.
Trims should be colour-matched to the skirting or wall finish rather than the flooring itself. These profiles are designed to blend into the skirting line, creating a clean transition without drawing attention to the edge of the floor.
Spare Planks
It’s a good idea to keep a few spare planks (usually a box) once installation is complete. These can be useful for future repairs or replacements and are best stored flat in a dry area.
11. Final Checks & After Installation Care
Once the installation is complete, remove all spacers from around the perimeter of the room and check that the floor surface sits flat and even. A quick visual check along the joints will help confirm everything is properly aligned before fitting skirting boards or trims.
Give the floor a light clean using a soft brush or vacuum to remove any dust from installation. Avoid using excess moisture at this stage.
Furniture can usually be placed back into the room after 24 hours, allowing the floor to settle as a complete floating surface. When positioning heavier items, lift rather than drag them into place to help protect the floor surface.
For ongoing care, regular sweeping or vacuuming will help keep the floor looking its best. Simple steps like using felt pads under furniture and placing mats at entrances can also help reduce everyday wear.
For full cleaning advice and long-term care recommendations, see our dedicated guide: LVT & SPC Flooring Care & Maintenance Guide.
12. Installation FAQs & Common Technical Questions
These FAQs address the most common technical issues that affect Click LVT (SPC) installations, particularly those relating to subfloor preparation, movement allowance, and joint engagement.
Click LVT (SPC) flooring requires a very flat and stable base to protect the locking mechanism. The subfloor must not vary by more than 3mm when measured under a 2-metre straight edge.
High spots can cause the plank edges to flex, placing stress on the joints. Low spots may allow movement beneath the boards, which can lead to noise, joint separation, or premature wear.
Uneven areas should be corrected before installation using a suitable levelling compound (for mineral subfloors) or appropriate overlay or repair methods (for timber bases).
In many cases, yes — particularly on ground floors or where moisture risk exists.
Although SPC itself is water-resistant, moisture from a concrete base can affect the room environment, perimeter trims, and in some cases contribute to odours beneath the floor.
Where moisture is suspected, where the slab is newly laid, or where no reliable moisture history is available, install a suitable DPM/PE membrane in accordance with flooring manufacturer guidance. Always follow specified recommendations for membrane type, thickness, and joint taping.
No. As a floating installation, SPC click flooring must be free to move as a single surface.
Heavy fitted units or fixed furniture can restrict movement, potentially leading to joint stress, gapping, or peaking.
Best practice is to install kitchen units first, then fit the flooring around them while maintaining the required 6mm expansion gap. Plinths or trims may then be used to conceal the perimeter without restricting movement.
In some situations, yes — provided the floor can move freely as one uninterrupted floating surface.
Transitions are generally recommended where:
- The installation passes through doorways or tight thresholds
- The floor exceeds approximately 10 metres in one direction
- The area exceeds roughly 100m²
- Different flooring types meet
Where movement may be restricted, a transition profile helps protect the integrity of the click system.
A consistent 6mm expansion gap must be maintained around:
- All walls and skirting boards
- Door frames and architraves
- Pipes and structural elements
- Kitchen units and other fixed objects
Common issues arise not from the visible perimeter, but from concealed pinch points — such as tightly undercut door frames or trims fixed into the flooring itself. Skirting boards and trims must always be fixed to the wall, never through the floor.
Yes, when temperature control is managed correctly.
The finished floor surface temperature must not exceed 27°C.
Underfloor heating should be switched off at least 48 hours before installation and remain off during fitting. After installation, the system should be reintroduced gradually, increasing temperature by no more than 2–5°C per day, or in accordance with manufacturer guidance.
Controlled temperature adjustment helps prevent sudden movement and reduces stress on the locking mechanism.
Do not force the joint.
Common causes include:
- Debris within the groove
- Incomplete engagement of the long-edge joint
- Subfloor unevenness placing tension on the plank
- Damage to the locking lip
Carefully remove the plank, inspect and clean the joint, and reinstall correctly. If the locking mechanism has been damaged, the plank should be replaced. Compromised joints rarely improve once installed and may reopen over time.

- Resolving short-end locking difficulty on second-row planks (2G click systems)
At approximately 14:52, the video clearly explains how to engage the short-end joint of the second plank in the second row when the long edge is already locked — a common point of confusion during installation. Correct sequencing and controlled angling are essential to prevent damage to the locking lip.
As with all visual references, always prioritise the expansion and movement rules outlined in this guide and follow the specific manufacturer instructions for your click profile.
Final Note
Correct preparation and careful installation are the foundations of a successful Click LVT (SPC) floor. When the subfloor is flat, expansion allowances are respected, and joints are fully engaged, the result is a stable, durable surface designed to perform reliably in everyday living.
Take your time, work methodically, and always prioritise accuracy over speed — particularly during set-out and the first few rows. Most long-term issues with floating floors can be traced back to preparation, restricted movement, or incomplete joint engagement.
If you are ever unsure about suitability, subfloor condition, or compatibility with underfloor heating, seek guidance before proceeding. A well-installed SPC floor should look clean, feel solid underfoot, and remain free to move as a single surface within the correct tolerances.
With the right preparation and attention to detail, Click LVT (SPC) flooring provides a practical, low-maintenance solution suited to modern UK homes.
