How to Find a Trustworthy Tiler in the UK

Look for membership of The Tile Association (TTA), the main UK trade body for tiling. Membership is not a legal requirement, but it signals training.

Ask to see previous work in a similar setting, such as a wet room or shower. This is more demanding than tiling a dry wall.

In a bathroom or wet room, a waterproofing layer, often called tanking, must go on before the tiles. Grout and tiles are not waterproof on their own.

Poor waterproofing can cause leaks hidden behind the tiles until real damage is done. Agree in writing whether tanking is included and which system will be used.

Large tiles need a very flat surface, and heavy tiles need a wall that can carry them. Ask whether the walls or floor need levelling or boarding first.

Tiling over underfloor heating needs flexible adhesive and sometimes a special membrane. Tell the tiler if you have it, or plan to install it.

• Tiles that sound hollow when tapped.
• Grout cracking within the first few months.
• Uneven edges between neighbouring tiles.
• Damp patches or staining on the other side of a shower wall.

If you notice any of these, contact the tiler early. Problems are easier to fix before water damage spreads.

Tiling faults can take months to appear, so a history of finished jobs is particularly useful. On Propvio, a review only appears once a homeowner has logged the job and the tiler has confirmed it.

Look for confirmed jobs in wet areas, not only kitchen splashbacks.

Ask for a written quote listing the tiles, adhesive, grout, any levelling, and whether waterproofing is included.
