Home Insurance Calculator
Our home insurance calculator provides an indicative buildings and contents insurance premium based on your property rebuild value, contents value, property type, and claims history. Choosing adequate cover levels is as important as finding a competitive premium — underinsurance can leave you seriously out of pocket after a major claim.

Buildings vs Contents Insurance
Buildings insurance covers the structure of your home. Contents insurance covers everything you would take if you moved. Mortgage lenders require buildings insurance as a condition of the loan. The rebuild cost (for buildings insurance) is not the same as the market value — underinsuring the rebuild cost leads to claims being paid proportionally less than the actual loss. Use our Buildings and Contents Calculator for a combined estimate, and our Contents Insurance Calculator to check your contents sum insured specifically.
How to Reduce Your Home Insurance Premium
Several practical steps reduce home insurance premiums without compromising cover. Increasing your voluntary excess — the amount you agree to contribute to any claim — lowers the premium in proportion to the risk the insurer retains. Improving security with insurer-approved deadlocks, window locks, and a burglar alarm (ideally Nacoss or SSAIB approved) qualifies for discounts from many insurers. Combining buildings and contents with the same insurer typically saves 5–15% versus separate policies. Comparing the market at each renewal remains the most effective single action — the FCA banned price-walking in 2022 but shopping around still reveals savings of 10–30% regularly. Always declare the rebuild value accurately using the BCIS calculator rather than guessing.
Frequently Asked Questions
Standard policies exclude general wear and tear, gradual deterioration, deliberate damage, and events deemed foreseeable.
Accidental damage covers unintentional one-off events like spilling wine on a carpet or breaking a TV. It is an optional add-on — without it, standard policies only cover named perils.
Standard home insurance typically covers personal equipment at home but may not cover business equipment or liability from home-based work. Inform your insurer if you work from home regularly.
Usually yes — combined policies typically offer a discount of 5–15% versus separate policies.
Making a small claim rarely makes sense — the premium increase in subsequent years typically exceeds the payout. Building a claims-free history over time significantly reduces premiums.
Enter your property type, number of bedrooms, and either rebuild cost or property value. The rebuild cost — the structural replacement cost from scratch — is what matters for buildings insurance, not the market value. Rebuild costs can be lower or higher than market value depending on location and construction type. If you do not know the rebuild cost, find it in your mortgage survey or use the BCIS House Rebuilding Cost Calculator. For contents, estimate replacement values room by room at current prices. Claims history significantly increases premiums at renewal — consider whether small claims are worth making versus self-insuring. Security improvements (alarm, deadbolts, Neighbourhood Watch) attract discounts with most insurers and are worth quantifying before your next renewal.
