Building quotes often differ because of assumptions: preparation, structural work, waste, access, materials, subcontractors and finishing. The right comparison is line-for-line, not simply cheapest versus most expensive.
A fair building quote should define what is included, what is excluded, the materials or specification being priced and how variations will be agreed. If two quotes are based on different scopes, their totals are not directly comparable.
We do not yet have enough genuine accepted comparisons in this trade to publish a meaningful FairerQuote average. This panel will switch on automatically once the minimum sample is reached.
