How to Get Accurate Quotes for Home Improvement Work

Understanding how to request and compare quotes properly can save significant money and prevent disputes later.

Home improvement projects regularly run over budget. The most common cause isn't unforeseen complications — it's quotes that were never genuinely like-for-like. Understanding how to request and compare quotes properly can save significant money and prevent disputes later.

Start With a Clear Brief

Before contacting any tradespeople, write down exactly what you want done. Be specific rather than general. "Bathroom renovation" is not a useful brief. Specifying the suite to be replaced, the tile area, appliances, and what structural work is needed gives tradespeople something to quote against accurately — and gives you a way to compare them fairly.

Get at Least Three Quotes

For any job over £500, get a minimum of three quotes. This establishes a market rate and highlights any quote that is very cheap (usually a warning sign) or very expensive.

Make Sure Quotes Are Like-for-Like

Ask each tradesperson to confirm what is and isn't included, particularly:

• Materials (brand, grade, specification)
• Waste disposal
• Surface preparation and making good
• Required certificates (Gas Safe, Part P, FENSA)
• Clearing up on completion

Fixed Price vs Day Rate

For most domestic work, request a fixed price. If a tradesperson will only quote day rate, ask for a written estimate of the number of days and a cap above which they'll notify you before continuing.

Variations and Change Orders

Agree upfront how changes to the scope will be handled. If you decide you want an extra socket or the tiler discovers the substrate needs replacing, you need a process for agreeing additional costs before they're incurred. A simple written message thread records any changes and the agreed additional cost, protecting both parties.
