💡Myth vs Reality
Common Myth
"A fixed quote means no extra costs"
The Reality
Fixed quotes still exclude unforeseen works like rot, asbestos, or structural issues that can't be predicted until work begins.
Common Myth
"Skipping the skip saves money"
The Reality
Proper waste disposal is a legal requirement. Cheap disposal methods often cause problems or fines later.
What to look for
- •Skip hire and waste removal — rarely included in basic quotes
- •Plastering — old tiles often damage walls when removed
- •Electrical work — new zones may need consumer unit upgrades
- •Tanking — essential for wet rooms and showers on timber floors
- •Subfloor repairs — hidden rot or damage only visible once work starts
Common mistakes
- •Assuming the quoted price is the final price
- •Not budgeting for remedial work discovered during strip-out
- •Forgetting about plumbing upgrades for modern systems
- •Ignoring the cost of temporary facilities during renovation
Quality considerations
- •Honest installers mention potential extras upfront
- •A 10-20% contingency is standard for bathroom renovations
- •Older properties typically have more hidden surprises
- •Good preparation work prevents bigger problems later
