How to Compare Builders’ Quotes Fairly
The cheapest quote is not always the cheapest job. Make sure you are comparing like with like.

Three quotes for the same job can vary wildly in price — and in what they actually include.
A clear brief and a structured comparison help you avoid surprise extras later.
Give everyone the same brief
Write down what you want done, materials or finishes you have chosen, and any drawings. Ask each builder to price against the same information. Vague briefs produce quotes that cannot be compared.
What a good quote shows
- Itemised costs for labour and materials
- What is excluded (e.g. skips, making good, decorating)
- Provisional sums for unknowns, clearly labelled
- Start date and expected duration
- Payment schedule tied to stages of work
- How long the price is valid
Estimates vs quotes
An estimate is a rough guide that can change; a quote is usually a fixed price for the defined work. Ask which you are getting. Large provisional sums can make a low quote look cheaper than it really is.
Beyond price
Consider availability, communication, insurance, references, and whether they belong to a trade association. A builder who asks lots of questions at the quoting stage is often thorough on site. See our contractor hiring checklist.
