Comparing contractors on a like-for-like basis

Lowest price is not lowest cost

A tender that looks cheaper often has exclusions, provisional sums or a programme that costs you later. The point of a tender is a consistent comparison, not a single number.

How to compare fairly

• Issue the same scope to every contractor
• Use a priced bill of quantities so each line is comparable
• Check inclusions and exclusions line by line
• Question provisional sums — they're a guess, not a price
• Weigh programme and references alongside price

The clarifications matter

Before you sign, issue clarifications and get written answers. A contractor that won't clarify before contract will be harder to manage during it.

Recommend, then appoint

A tender review gives you a recommendation with reasoning. You appoint. The right contractor is the one suited to the work and the relationship, not just the cheapest line.
