Our Promise

Built for families,
not advertisers.

01
Free, forever
Every tool on CostWatch is free to use and will remain free. We don't charge, we don't have a premium tier, and we never will. The people who need these tools most shouldn't have to pay for them.
02
Zero advertising
No banner ads, no sponsored results, no affiliate links dressed up as recommendations. If a dealer appears in our comparison, it's because they're good value — not because they paid us.
03
No tracking, no accounts
We don't know who you are. We don't want to. No cookies, no analytics, no data sold to third parties. Your postcode is sent to the price API and nowhere else. That's the whole story.

"The cost of living crisis has hit ordinary families hardest. Information is power — and price information should be free to everyone, not locked behind paywalls or buried under advertisements."
