Method & assumptionsAuthoritative sources

This home insurance calculator estimates annual premium costs for buildings cover, contents cover, or a combined policy based on the property and household details you provide. Key inputs include your property's rebuild value (for buildings cover), the estimated replacement cost of your contents, your postcode risk profile, and any previous claims history. Premiums are illustrative rather than guaranteed quotes — actual prices are set by individual insurers and depend on detailed underwriting criteria not captured in a simple calculator. Following financial regulator pricing reforms introduced in 2022, insurers are prohibited from offering new customers a lower price than they would offer an equivalent renewing customer, which has made the market more transparent. The calculator excludes specialist covers such as flood reinsurance under Flood Re, accidental damage extensions, and high-value item endorsements.

Common mistakes

  • !Using optimistic assumptions without testing a more cautious scenario.
  • !Comparing outputs from different tools without checking that the inputs match.
  • !Treating the result as a final quote instead of a planning estimate.
  • !Rounding inputs too aggressively.

What to do next

  • Try at least one more scenario so you can compare a realistic range.
  • Use the related calculators below to cross-check the decision from another angle.
  • Write down the key outputs from your best scenarios before you decide.
  • If the result surprises you, change one input at a time to isolate the driver.
