What flooring really costs per square metre, once waste and underlay are included

10 July 2026

The price on the shelf is per square metre of board. The price you pay is per square metre of floor, and the difference is waste, underlay, trims and delivery. For a typical room those extras add 30% to 60% to the shelf price, which is why flooring budgets run over more often than almost any other DIY job.

Here is the real cost stack, and where you can actually save.

The real cost stack

LineTypical costNotes
Boards (shelf price)€10 to €80/m²laminate at the bottom, engineered oak at the top
Waste allowance+5% to 20% of board costdepends on pattern and room shape
Underlay€3 to €6/m²more for acoustic or underfloor-heating grades
Trims, thresholds, scotia€2 to €4/m² equivalentper doorway and exposed edge
Delivery€30 to €60 flatboards are heavy; few cars take 15 packs
Fitting (if hired)€10 to €25/m²herringbone and chevron at the top end

The shelf price is the only line people compare, but the waste line is the one that varies most, and the only one you control without changing the floor.

Waste multiplies the board price

Waste is not a fixed fee; it scales with what the boards cost. At 8% waste, a €15/m² laminate loses you €1.20/m². The same 8% on €60/m² engineered oak is €4.80/m², and if you lay that oak in herringbone at 18% waste, you are spending €10.80 per square metre on offcuts.

Two consequences:

  • The more expensive the board, the more planning pays. Cutting waste from 18% to 12% on a 20 m² herringbone floor in €60 boards saves €72, for an hour of layout planning.
  • A "cheaper" pattern can beat a cheaper board. The same €60 oak in a running bond at 7% waste costs less per finished square metre than a €55 board in herringbone.

The waste ranges by pattern are covered in detail in the flooring waste percentage guide; the short version: straight lays 5% to 8%, complicated rooms 8% to 12%, diagonal 10% to 15%, herringbone and chevron 15% to 20%.

A worked example

An 18 m² living room in €25/m² laminate, straight lay, one alcove:

  • Boards: 18 m² × 1.10 (10% waste) = 19.8 m² → at pack coverage 2.22 m², 9 packs = €499 (round pack prices)
  • Underlay: 18 m² × €4 = €72
  • Scotia + one threshold: €55
  • Delivery: €40

Total: about €666, or €37/m², not €25/m². The €12 gap is invisible on the shelf and entirely predictable at the planning stage. Run your own numbers in the flooring calculator, or measure your room properly first.

Where not to save

  • Underlay. The €1/m² saving on thin underlay costs you acoustics, moisture protection and warranty cover.
  • The waste allowance itself. Buying exactly the room area and hoping is how floors end up one pack short with a discontinued batch. Reduce waste by planning the layout, not by under-buying.
  • Returns as a strategy. Most retailers take back unopened packs, but restocking fees and the second delivery eat the margin.

The one line you can actually shrink

Underlay, trims and delivery are what they are. The waste line is the only place a better plan turns directly into money: a layout that reuses offcuts as row starters, avoids sliver rows and matches the stagger to your board length routinely lands at the bottom of the waste range for the pattern.

That is a counting problem, not a judgement call, which is why doing it with software beats doing it with a percentage. Work out how much flooring you need, then let the layout tell you the exact pack count.

Frequently asked questions

How much does laminate flooring cost per square metre fitted?
Budget the board price plus 10% to 20% waste, €3 to €6/m² for underlay, €2 to €4/m² for trims and thresholds spread across the room, and fitting if you are not laying it yourself. A €20/m² board typically lands at €28 to €35/m² supplied, before labour.
Is it cheaper to buy more expensive flooring with less waste?
Often, yes. Waste multiplies the board price, so a €40/m² herringbone floor at 20% waste costs €8/m² in offcuts alone. Planning the layout to cut waste from 20% to 12% saves more than switching to a €35 board.
What is the cheapest way to reduce flooring cost?
Reduce the waste, not the board quality. The waste percentage is the only line in the budget you can change without changing what ends up on your floor, so plan the layout before buying instead of adding a flat safety margin.
