Common pitfalls
- A deposit above 30% before work starts.
- Lump sums without quantities or unit prices.
- No brand or model for equipment.
- No mention of VAT, validity or timeline.
- Disposal, scaffolding or connections missing.
- A price far below other quotes, unexplained.
Questions to ask the contractor
- Is “Scaffolding (erection, hire, removal)” included in the price?
- Is “Removal of existing work” included in the price?
- Is “Insulation (thickness, material)” included in the price?
- Could you break down the lump sums (quantities, unit prices, materials)?
- Which warranty applies (SIA 118, duration)?
