Top tips
Hiring a flooring, without the regret.
Four moves that separate a smooth job from a nightmare.
Cracked tiles on flexing subfloor
Without proper backer board on timber subfloors, tiles crack within months. Always fit 6mm backer or NoMorePly.
Lippage
Large-format tiles show edge mismatches. Lippage levelling system (clips and wedges) brings tiles flat during set.
Grout cracking
Cement-based grout cracks at flexing joints. Use silicone at floor-to-wall junctions.
UFH cracking
Non-flexible adhesive cracks under thermal expansion. Use a flexible (S1 or S2) adhesive for UFH.

Flooring explained
Tile flooring is the most durable hard finish for UK kitchens, bathrooms and hallways. Porcelain has overtaken ceramic for floors thanks to better wear resistance. Expect to pay £40–£140 per m² fitted including tiles, adhesive, grout and labour.
What Does the Work Involve?
The fitter checks the subfloor for level (max 3mm in 2m for tiles up to 30 × 30; tighter for larger). On timber floors, fits 6mm tile-backer board or NoMorePly with screws every 200mm. Sets out the room from the centre, snaps chalk lines, mixes adhesive, combs it onto the subfloor with a notched trowel, lays tiles with tile spacers, allows 24 hours cure, then grouts.
Typical Costs
| Item | Low (£) | High (£) | Notes |
|---|---|---|---|
| Budget ceramic tiles per m² | 15 | 30 | Stock sizes, plain colours |
| Mid-range porcelain per m² | 25 | 55 | Anti-slip rated |
| Large-format porcelain per m² | 40 | 90 | 600 × 1200mm+ |
| Premium designer porcelain | 60 | 140 | Stone-effect, marble-look |
| Tile backer board per m² | 8 | 20 | If timber subfloor |
| Adhesive and grout per m² | 5 | 15 | Flexible adhesive for UFH |
| Install labour per m² | 20 | 50 | Higher for large-format |
How Long Does It Take?
Kitchen 15 m²: 1–2 days laying, 1 day grouting. Hallway and bathroom: 1 day. Large-format tiles add complexity — 600 × 1200mm formats require 2 fitters and slow setting time.
DIY or Professional?
Professional. Subfloor prep, mixing adhesive to the right consistency, and grouting cleanly are all learned skills. Cracked tiles within 6 months are usually the result of poor subfloor prep.
Choosing the Right Tradesperson
A tiler. Ask about subfloor — on timber floors they should fit backer board, not lay direct. Confirm anti-slip rating for wet areas (R10 minimum bathroom, R11+ wet rooms). Get the grout colour confirmed before fitting.
UK Regulations
No specific Building Regs for tiles. Slip-resistance ratings R10–R13 apply in commercial; recommended in domestic wet areas. Tile backer board fire rating is A1.
Common Problems
- Cracked tiles on flexing subfloor: Without proper backer board on timber subfloors, tiles crack within months. Always fit 6mm backer or NoMorePly.
- Lippage: Large-format tiles show edge mismatches. Lippage levelling system (clips and wedges) brings tiles flat during set.
- Grout cracking: Cement-based grout cracks at flexing joints. Use silicone at floor-to-wall junctions.
- UFH cracking: Non-flexible adhesive cracks under thermal expansion. Use a flexible (S1 or S2) adhesive for UFH.
Frequently Asked Questions
Porcelain or ceramic?
Porcelain — denser, more durable, lower water absorption. Use for floors. Ceramic is fine for walls but wears faster on heavy floors.
Large-format tiles — worth the premium?
Yes for modern aesthetic — fewer grout lines, more contemporary. Need flatter subfloor and skilled fitter. 600 × 1200mm is the current sweet spot.
Can I tile over timber floor?
Yes — but always fit 6mm tile-backer board (HardieBacker, NoMorePly, MarmoxBoard) first. Direct tiling on timber cracks within months.
Tiles over UFH?
Yes — tiles are the best floor for UFH. Use flexible adhesive (S1 minimum). Heat-up over 3 weeks gradually after laying.
How long do tile floors last?
Quality porcelain tiles: 50+ years. Grout may need refreshing every 10–15 years.
Best grout for floors?
Cement-based grout for general floors. Epoxy grout (more expensive) for kitchens, wet rooms, and stain-prone areas — fully waterproof and stain-resistant.
