Fitting Costs by Flooring Type

Professional flooring fitting is charged per square metre. Here are the typical UK rates in 2026:

DIY vs Professional: Decision Guide

Choose DIY If:

• You are fitting click-lock laminate, click LVT, or click SPC vinyl
• The room is a simple rectangle with few obstacles
• The subfloor is level and in good condition
• You have basic DIY skills and own (or can borrow) the necessary tools
• You have a full day available for a standard room
• You are comfortable using a saw (hand saw, jigsaw, or mitre saw)

Choose Professional If:

• You are fitting carpet, sheet vinyl, solid hardwood, or tiles
• The room has complex shapes, many doorways, or obstacles
• The subfloor needs significant preparation (levelling, DPM, plywood overlay)
• You want a guaranteed professional finish
• The flooring is expensive and you cannot afford mistakes
• You are fitting stairs, hallways, or multiple connected rooms

Subfloor Preparation

Proper subfloor preparation is the single most important factor in a successful flooring installation. Poor prep leads to creaking, gaps, uneven surfaces, and premature wear. Here is what you need to check and do before laying any flooring:

1. Check for Level

Use a long spirit level (1 metre or longer) or a straight edge to check the subfloor for high and low spots. The tolerance depends on the flooring type:

• Laminate and click vinyl: Within 3mm over 1 metre
• Glue-down vinyl and LVT: Within 2mm over 1 metre
• Tiles: Within 2mm over 2 metres
• Carpet: More forgiving, but significant dips will be visible

If the subfloor is out of tolerance, use self-levelling compound (SLC) to create a flat surface. SLC costs £5–10/m² including material and labour, and typically takes 24–48 hours to dry before flooring can be laid.

2. Check for Moisture

Concrete subfloors can contain significant moisture, especially in ground-floor rooms. Use a moisture meter or the “plastic sheet test” (tape a 1m² piece of polythene to the floor for 48 hours and check for condensation underneath). If moisture is present, you need a DPM (damp-proof membrane) under the underlay. Most laminate underlay with a built-in DPM costs only £0.50–1.00/m² more than standard underlay.

3. Clean and Clear

Remove all old flooring, adhesive residues, carpet tack strips, protruding nails, and debris. The subfloor must be clean and dry. Vacuum thoroughly — even small debris under underlay can create uncomfortable bumps and telegraph through thin vinyl.

4. Fix Squeaky Floorboards

For timber subfloors, screw down any loose or squeaky boards before laying new flooring. Use 40mm chipboard screws driven into the joists. A new floor will not fix an existing squeak — it will amplify it.

5. Acclimatise the Flooring

Laminate and engineered wood must be stored in the room where they will be fitted for at least 48 hours before installation. This allows the material to adjust to the room’s temperature and humidity, reducing the risk of expansion or contraction after fitting. Leave the packs sealed but laid flat in the room.

How to Lay Laminate Flooring (Step by Step)

Laminate is the most popular DIY flooring project. Here is the process:

Tools Required

• Tape measure and pencil
• 10mm spacers (included in most laminate installation kits)
• Pull bar and tapping block
• Hand saw, jigsaw, or mitre saw
• Stanley knife (for cutting underlay)
• Spirit level
• Knee pads
• Multi-tool (optional, for cutting door frames)

A basic laminate installation kit costs £10–20 from B&Q, Wickes, or Screwfix and includes spacers, pull bar, and tapping block.

Step 1: Prepare the Subfloor

Clean, level, and dry. Fix any squeaky boards. Remove old flooring and debris.

Step 2: Lay the Underlay

Roll out the underlay across the room, silver (DPM) side down on concrete subfloors. Butt-join the edges (do not overlap) and tape the joins with the tape provided. Trim to fit around the walls.

Step 3: Plan the Layout

Measure the room width and divide by the plank width. If the last row would be less than 5cm wide, trim the first row narrower to balance both sides. Decide which direction to lay the planks (usually parallel to the longest wall or towards the main light source).

Step 4: Lay the First Row

Start in the far-left corner of the room. Place 10mm spacers against the wall. Lay the first plank with the tongue facing the wall. Click the next plank into the end of the first and continue along the wall. Cut the last plank to fit, leaving a 10mm gap at the end wall. Use the offcut to start the next row (if it is at least 30cm long).

Step 5: Continue Laying Rows

Angle each plank into the long edge of the previous row at approximately 20 degrees and press down to click into place. Use the tapping block (never hit the plank directly) to close any gaps along the short edges. Stagger end joints by at least 30cm between rows for stability and visual appeal.

Step 6: Fit Around Obstacles

For radiator pipes, drill a hole slightly larger than the pipe diameter, make a straight cut to the hole, slot the plank around the pipe, and glue the cut piece back in place. For door frames, use a multi-tool to cut the bottom of the frame flush with the top of the laminate, then slide the plank underneath.

Step 7: Fit the Last Row

Measure the width needed (room width minus spacer minus current floor edge) and cut planks lengthways. Use the pull bar to click the last row into place, as the wall prevents using the tapping block.

Step 8: Finish

Remove all spacers. Fit scotia beading or re-attach skirting boards to cover the expansion gaps. Fit threshold strips at doorways. Trim doors if needed.

Installation Tips by Flooring Type

Click LVT / SPC Vinyl

Very similar to laminate installation. Click-lock mechanism, floating floor, spacers around the perimeter. The main difference is that vinyl is softer and easier to cut (often just score and snap). No saw needed for most cuts.

Carpet

Professional fitting is recommended. The process involves: nailing gripper rods around the perimeter (10mm from the wall), laying underlay inside the gripper rods, rolling out the carpet and rough-cutting with 10cm overlap on all walls, using a knee kicker to stretch the carpet onto the gripper rods, trimming the excess with a carpet knife, and tucking the edges into the gap between the gripper rods and wall.

Tiles

Start by finding the centre of the room and snapping chalk lines. Dry-lay tiles from the centre to check the layout and ensure cut tiles at the edges are not too narrow. Mix and apply adhesive with a notched trowel, lay tiles working from the centre outwards, use spacers for consistent grout lines, wait 24 hours for adhesive to set, then grout.

Engineered Wood

Click-lock engineered wood installs like laminate. Glue-down and nail-down methods require more experience. Allow the boards to acclimatise for 72 hours (longer than laminate due to the real wood content). Use the manufacturer’s recommended adhesive or fixing method.

Additional Installation Costs

Beyond the fitting cost per m², budget for these common extras:

Finding a Professional Fitter

If you decide to hire a professional, here is how to find a reliable fitter:

Where to Find Fitters

• Flooring retailers: Carpetright, Tapi, and Flooring Superstore have their own fitting teams or approved contractors. Often included free with purchase.
• Checkatrade: Verified tradespeople with reviews and qualifications. Filter by “flooring fitter” and your postcode.
• MyBuilder: Post your job and receive quotes from local fitters.
• Local recommendations: Ask neighbours, friends, or local Facebook groups. Word-of-mouth recommendations are often the most reliable.

What to Ask

• Is the quote fixed or per-m²? Does it include subfloor prep, door trimming, and threshold strips?
• What insurance do you carry? (Public liability of at least £1 million is standard.)
• Can you provide references or photos of recent work?
• How long will the job take?
• Who supplies the underlay and accessories — you or the fitter?
• What guarantee do you offer on fitting? (12 months minimum is reasonable.)

Common Installation Mistakes to Avoid

1. Skipping subfloor preparation: The number one cause of flooring failure. A bumpy, damp, or dirty subfloor will ruin any flooring, no matter how good the product.
2. Not acclimatising laminate/wood: Leads to expansion, buckling, or gaps after fitting.
3. Forgetting expansion gaps: Laminate and click vinyl must have 10mm gaps around the perimeter. Without gaps, the floor will peak (buckle upward) when it expands.
4. Cutting door frames too high: The flooring should slide under door frames, not up to them. Cut frames flush with the flooring surface for a clean finish.
5. Not staggering joints: End joints should be staggered by at least 30cm between rows. Non-staggered joints look poor and create structural weak points.
6. Forcing boards: If a board will not click easily, do not force it. Check for debris in the click channel, check the board is the right way round, and check the angles are correct.
7. Laying over uneven subfloor: Even 2–3mm deviations create hollow spots that creak underfoot. Use SLC or sand high spots before laying.
8. Not buying from the same batch: Different production batches can have slightly different shades. Buy all your flooring at once from the same batch number.
