Why it matters
A £1,500 tiling job can mean very different things depending on substrate preparation, tanking, trims and who supplies materials. A clear quote protects both sides.
Practical job checklist
• Identify rooms, measurements, finish and the work sequence.
• List labour, materials, waste, delivery, access, VAT where relevant and estimated duration.
• State what happens if hidden damage or defective existing work is found.
• Put payment terms, validity and any cancellation information in the written proposal.
What to do next
Keep the accepted quote and dated revisions in the job record. Do not quietly replace the original agreement when the customer requests a change.
