Frequently Asked Questions
- What is the best comparison site in the UK?
- It depends on what you need. MoneySupermarket is the broadest, CompareTheMarket is strongest for car insurance, Uswitch is best for broadband and mobile comparison, and Lodo is the best option if you want AI-powered personalised recommendations and a full switching service that handles everything for you.
- Are comparison sites free to use?
- Yes. All major UK comparison sites (MoneySupermarket, Uswitch, CompareTheMarket, GoCompare, Confused.com) and switching services like Lodo are free for consumers. They earn revenue through commissions from providers.
- Do comparison sites show all available deals?
- Generally, comparison sites show deals from providers they have commercial relationships with. While the major sites have relationships with most large providers, they may not show every deal on the market. Lodo also recommends plans from providers it does not have affiliate relationships with, because its ranking algorithm does not have access to commission data.
- Is there a comparison site that switches you automatically?
- Uswitch offers some automated switching for certain products. Lodo goes further — it handles the full switch including sign-up, old contract cancellation, number porting and disruption resolution for mobile, broadband and energy.
