1) Why Low Bids Attract and Risk
Restoration price depends on materials, craft labour, trial panels, and conservation approvals. If these are omitted, the difference returns as variations. Very low bids often mean narrow scope, lower quality, or a plan to recover through extras. Choose the most explainable, comparable bid.
2) One Common Scope
Issue one specification, summary bill, and quantity schedule, and ask all bidders to price the same items. Bids that deviate from the approved project documents should be corrected or excluded. See our historic building restoration cost guide.
3) Spotting Missing Items
Typical gaps are scaffolding, protection, waste and transport, trial areas, material analysis, board documentation, site safety, and handover costs. Undefined lump sums are the riskiest lines; ask for an exclusions list and confirm tax and overhead.
4) Contractor Qualifications
Check experience on similar work, the technical team, authorisation documents, references, workload, and the subcontracting structure. Visit reference projects where possible.
5) Contract and Variations
Include scope, duration, guarantees, escalation, a written variation procedure, and a unit-rate list for unforeseen work found in historic fabric.
6) Progress Payments and Escrow
Avoid large advances; pay against measured, approved quantities with photographic reports. Retention and guarantees add protection, and in some projects an escrow-style release per stage may be considered with legal advice. Independent checks matter for hidden layers.
7) Scoring Bids
Weight price, scope clarity, team, references, programme, financial strength, and contract compliance. Ask for explanations of unusually low bids. Our construction and restoration teams can review your file independently.
