“They have great reviews.”
Do the reviews form a consistent picture across different sources?
BUILDER DUE DILIGENCE, MADE CLEAR
Before you hand over a substantial deposit or sign a contract, find out more about the business behind your builder's quotation.
RESEARCH-LED. EVIDENCE-FOCUSED.
DESIGNED FOR HOMEOWNERS.

THE DECISION BEFORE THE BUILD
Recommendations, photographs and five-star ratings can help you find a builder. But they may not tell you who operates the business, how long it has traded, or whether claims being made can be checked.
Builder Background brings relevant information together in a clear written report so you can make a more informed decision before committing to major work.
What can be checked? ↗LOOK BEYOND FIRST IMPRESSIONS

ABOUT THE FOUNDER
Builder Background was founded by Chris, a former Metropolitan Police officer with 15 years' service, including specialist operational roles.
His experience includes evidence gathering and assessment, preparing case papers and giving evidence in court. That methodical approach informs how we organise research and distinguish facts from assumptions.
Builder Background is an independent private service, not affiliated with the police. We do not offer legal representation, building inspections or guarantees about contractors.
