Flooring over underfloor heating (UFH) in Dublin new builds.
Almost every A2/A3-rated new-build home and rear extension in Dublin uses low-temperature air-to-water heat pump underfloor heating .
Here is the engineering and installation guide for glue-down LVT, engineered oak and low-tog laminate over water and electric UFH systems in Dublin.

Comparing floors over heat-pump underfloor heating
Thermal resistance (Tog / m²K/W) determines how fast warmth reaches your room and how hard your heat pump works.
| Service / Flooring Type | Typical 2026 Dublin Price | Specification & What Is Included |
|---|---|---|
| Herringbone floor fitting — labour only (Click, T&G or Glue-Down) | €35 to €65 a m² | Laser centre-line set-out, 45° mitred cuts, door frame undercutting and threshold trims (add €12–€20/m² for perimeter border). |
| Herringbone engineered oak or LVT — full supply & fit | €85 to €145 a m² | Includes trade-grade herringbone blocks (AC5 laminate, LVT or 14mm engineered oak), flexible MS polymer adhesive or underlay, and fitting. |
| Laminate floor fitting — labour only (straight plank) | €18 to €30 a m² | Click-system AC4/AC5/AC6 straight-plank laminate laid over 3mm–5mm acoustic/UFH underlay with staggered joints. |
| Engineered wood floor fitting — floating or secret-nailed | €25 to €38 a m² | 14mm–20mm engineered oak planks floated over acoustic DPM underlay or secret-nailed to timber joists. |
| Engineered or solid oak — full glue-down (UFH compatible) | €35 to €50 a m² | Full-trowel Bona R848 / Wakol MS polymer flexible adhesive bond directly to primed concrete or anhydrite screed. |
| Glue-down LVT (Amtico / Karndean / Moduleo) — labour + smoothing screed | €38 to €62 a m² | Subfloor primer, 3mm fibre-reinforced latex self-levelling compound, feather-finish sanding and high-temperature pressure-sensitive adhesive. |
| Subfloor self-levelling compound (3mm–6mm latex screed) | €18 to €32 a m² | Ardex, F.Ball Stopgap or Mapei fibre-reinforced levelling screed to achieve SR1 flatness (+/- 3mm over 2m). |
| Liquid DPM surface moisture barrier (2-part epoxy) | €16 to €26 a m² | Protects timber and LVT floors against residual construction moisture up to 95%–98% RH in new-build concrete slabs. |
| Skirting board supply & mitred fitting (MDF or solid oak) | €12 to €24 a linear m | Removing old skirtings, scribing internal corners, mitring external corners, pinning, gluing and caulking top edge. |
Technical Breakdown
Four mandatory rules before fitting over a UFH screed
1. Glue-down LVT (0.20–0.30 Tog) — Highest UFH efficiency
2.5mm dryback LVT bonded directly to a latex-screeded UFH slab has almost zero thermal resistance (0.025 m²K/W), letting heat transfer almost as fast as porcelain tile while feeling warm underfoot when the heating is off.
2. Full-trowel bonded 14mm–15mm Engineered Oak (0.90–1.10 Tog)
Gluing 14mm engineered oak directly to the screed with Bona R848 / Wakol MS polymer adhesive eliminates the insulating air gap beneath the boards, keeping total thermal resistance around 0.10–0.11 m²K/W (well inside the 0.15 m²K/W limit).
3. Floating 8mm–12mm Laminate with Low-Tog Underlay (1.0–1.35 Tog)
If floating laminate or click herringbone over UFH, never use standard 3mm foam underlay. We use perforated high-density rubber/mineral UFH underlay (such as Quick-Step Heat / Thermo-Slent at 0.30–0.35 tog) so the combined system stays under 1.35 tog.
4. Mandatory UFH Commissioning & Step-Up/Step-Down Protocol
Before laying any floor over a new sand-and-cement or anhydrite screed, the UFH system must run its full EN 1264 heat-up commissioning cycle, be switched off 48 hours before installation, and then be brought back up gradually by 2°C–3°C per day after fitting.

Your floor area × our 2026 Dublin price guide
€1,400 to €2,600
40 m² at €35–€65/m² for herringbone floor fitting (labour only). Includes door frame undercutting and threshold profiles; subfloor self-levelling or skirting removal is itemised separately if needed.
- Every quote includes moisture testing, door architrave undercutting and threshold trims.
- Subfloor latex self-levelling compound (€18–€32/m²) ensures zero bounce on herringbone and LVT.
How this estimate is worked out
Our calculator multiplies your area by 2026 Dublin floor layer rates: €18–€30/m² for straight-plank laminate labour, €28–€45/m² for engineered wood labour, €35–€65/m² for herringbone labour, €68–€115/m² for LVT supply & fit, and €85–€145/m² for herringbone supply & fit.

Flooring Over Underfloor Heating Dublin questions answered
Can I lay 12mm herringbone laminate over underfloor heating in a new build?
Yes, provided the subfloor is levelled to SR1 (+/- 2mm over 2m) and you pair the 12mm laminate (~0.90 tog) with a dedicated ultra-low-tog UFH underlay (~0.30–0.35 tog), keeping the combined total around 1.25 tog (below the 1.50 tog maximum).
Why is gluing engineered wood better than floating it over underfloor heating?
A floated wood floor traps a microscopic air cushion between the plank and the underlay, adding ~0.35–0.50 tog of insulation. Full-trowel bonding removes that air gap completely, cutting heat-up lag time in half and lowering heat-pump electricity bills.
What is the maximum floor surface temperature allowed for wood and LVT?
Both European wood flooring standards (BS 8201) and LVT manufacturers (Amtico, Karndean, Moduleo) specify a maximum floor surface temperature of 27°C — including beneath rugs, beanbags or low-plinth furniture.
Can you fit flooring in a new-build estate in Swords, Lucan or Sandyford right after snagging?
Yes — new-build handovers are one of our primary specialties. The fitter checks residual screed moisture on snagging day, applies a liquid epoxy DPM if the builder's slab is still above 75% RH, levels any trowel marks, and fits your floor before furniture delivery.
