In the UK's damp climate, choosing the right material and ensuring proper moisture protection is essential to prevent warping or mould. This guide outlines the professional process, realistic costs for 2025/26, and the regulatory standards you need to know before hiring a contractor.
What Does the Work Involve?
- Site Survey: Measuring the area and testing subfloor moisture levels (essential for concrete floors).
- Uplift and Disposal: Removing old carpets, laminate, or tiles and disposing of them via skip or waste carrier.
- Subfloor Preparation: Levelling uneven concrete with a self-levelling compound or overboarding timber floors with 6mm–9mm plywood.
- Moisture Protection: Laying a Damp Proof Membrane (DPM) if moisture readings are high.
- Installation: Laying the chosen material (Carpet, LVT, Laminate, or Wood) with the appropriate underlay.
- Finishing Touches: Fitting door thresholds, trimming doors to clear the new floor height, and installing skirting boards or scotia beading.
Typical Costs
| Item / Service | Low £ | High £ | Notes |
|---|---|---|---|
| Labour (Day Rate) | £150 | £300 | Higher in London and SE. |
| Carpet (Inc. Underlay) | £25 | £65 | Per m²; wool blends cost more. |
| Laminate Flooring | £30 | £70 | Per m²; price includes mid-range boards. |
| LVT (Click or Glue-down) | £45 | £95 | Per m²; includes intensive floor prep. |
| Engineered Wood | £80 | £160 | Per m²; depends on oak thickness/grade. |
| Subfloor Prep (Screeding) | £15 | £25 | Per m² for materials and labour. |
Total costs are heavily influenced by the condition of the subfloor and the complexity of the room's layout. Expect to pay a premium for "herringbone" or "parquet" patterns, which can increase labour time by 50% or more compared to standard straight planks.
How Long Does It Take?
- Single Bedroom (Carpet/Laminate): 3–5 hours. Usually completed within half a day if the room is clear.
- Average Lounge (LVT/Engineered Wood): 1–2 days. This includes time for subfloor prep and intricate cutting around radiators.
- Full Ground Floor (Open Plan): 3–5 days. Requires more time for levelling compounds to cure before the flooring can be laid.
- Acclimatisation: Remember that wood and laminate often need 48–72 hours sitting in the room before installation to adjust to the temperature.
DIY or Professional?
While "click-lock" laminate is a popular DIY project, professional installation is highly recommended for LVT, carpet, and solid wood. Professionals possess the specialist tools—such as power stretchers for carpets or moisture meters for concrete—that ensure a long-lasting finish.
If you are installing flooring in a bathroom or kitchen, professional fitting is vital to ensure water-tight seals that prevent subfloor rot.
Choosing the Right Tradesperson
- Check Qualifications: Look for fitters who are members of the National Institute of Carpet and Floorlayers (NICF) or the Contract Flooring Association (CFA).
- Verify Insurance: Ensure they have Public Liability insurance (minimum £1 million) to cover any accidental damage to your property.
- Ask for References: Request photos of their recent "finishing" work, specifically around door frames and hearths.
- Questions to Ask:
- Do you include the cost of waste disposal in your quote?
- Will you test the subfloor for moisture before starting?
- Do you provide a guarantee on the labour as well as the manufacturer's warranty?
- Will you shave the bottoms of the doors if the new floor is higher?
UK Regulations
- Building Regulations Part E: If you live in a flat or apartment, you must comply with sound insulation standards. You may be required to use specific high-decibel acoustic underlays.
- Building Regulations Part L: Relevant if you are installing underfloor heating (UFH) alongside your new floor to ensure thermal efficiency.
- Asbestos Awareness: In homes built before 2000, old vinyl tiles or "bitumen" adhesive may contain asbestos. Professionals should flag this and may require a specialist test before removal.
Common Problems
- Poor Expansion Gaps: If a gap isn't left around the perimeter, laminate and wood floors will buckle and "peak" when the weather changes.
- Subfloor Telegraphing: If the subfloor isn't perfectly smooth, imperfections will show through thin LVT or vinyl over time.
- Moisture Damage: Laying wood or LVT over a "green" (damp) concrete screed will lead to adhesive failure or warped boards.
- Bouncing Floors: Occurs when flooring is laid over an uneven subfloor without proper levelling, leading to joint failure.
Frequently Asked Questions
Can I lay new flooring over my old tiles or laminate?
It is generally discouraged. Laying over old flooring can cause height issues with doors and appliances, and if the old floor moves or fails, your new floor will too. It is always best to strip back to the original subfloor.
Do I need to remove my skirting boards?
For the cleanest finish, yes. Removing skirtings allows the floor to be laid underneath them. If you leave them on, the fitter will use "scotia" or "beading" to cover the expansion gap, which some homeowners find less attractive.
Is LVT better than laminate for a kitchen?
Yes. LVT (Luxury Vinyl Tile) is waterproof and much more durable in high-moisture areas. Laminate, even "water-resistant" types, can swell if water seeps into the joints for prolonged periods.
How long should I leave a new concrete screed to dry?
The general rule is one day of drying time for every millimetre of thickness for the first 40mm. A professional will use a hygrometer to confirm the floor is below 75% Relative Humidity (RH) before fitting.
Will the fitter move my furniture?
Some fitters include furniture moving in their service, but many expect rooms to be completely clear. Always clarify this beforehand, as it may incur an extra "handling fee" or require a second person on-site.
