Specification and comparisons

Comparing decorating tenders on a fair basis

Several tender documents spread on a table for side-by-side comparison.

Comparing tenders by total figure alone assumes every contractor priced against the same scope, which is rarely true unless the tender documents were tight enough to prevent it. A fair comparison means checking what sits behind each number before ranking them, not after the contract is already signed.

Check that every tender priced the same scope

Before comparing figures, confirm each tenderer worked from the identical specification and site information. A lower price built on a smaller assumed scope, fewer coats or a lighter preparation standard is not actually a lower price for the same job.

Query gaps and assumptions before ranking

Where a tender document leaves room for interpretation, ask each tenderer to confirm their assumptions in writing before final comparison, rather than assuming silence means they read the specification the same way as everyone else.

  • Confirmed coat counts against the specified system
  • Confirmed preparation standard for the surfaces described
  • Confirmed inclusion or exclusion of access equipment

Weigh more than the bottom line

Proposed programme, sequencing around any occupied areas, and how clearly a tenderer has responded to the specification all give a useful sense of how the job will actually run, separate from the number at the bottom of the page.

  • Clarity and detail of the written response itself
  • Proposed sequencing around any occupied areas
  • How specific queries were answered during the tender period

Document the comparison for accountability

A short written comparison table, even for a modest job, protects the decision if it is ever questioned later, and it forces genuine comparison rather than an instinctive choice based on the headline figure alone.

Questions we are asked about this

Should the lowest tender always be queried?

It is worth checking that a notably lower figure has priced the identical scope before assuming it represents better value, rather than a narrower interpretation of the work.

Can I ask tenderers questions during the process?

Yes, and it is good practice — questions and answers should ideally be shared with all tenderers so everyone is pricing with the same information.

How many tenders should I compare?

Enough to give a genuine comparison, but tendering too widely on a specification that is not tight can waste everyone's time interpreting an ambiguous scope differently.
