CostWatch was built for ordinary UK families. No ads. No tracking. No accounts. Just clean, fast tools that show real prices — fuel, precious metals, energy, and soon groceries. The average household overspends £3,800 a year simply by not comparing. Petrol alone can vary 20p per litre between stations on the same road. Gold & silver premiums vary 3–8% dealer to dealer. Nisab thresholds change daily. Information is power — and price information should be free to everyone, not buried under ads or paywalls. CostWatch is our attempt to fix that. https://www.costwatch.co.uk
