Which Business Insurance Types Are Commonly Relevant?

Answer a few questions about your business to see general information about cover types commonly considered by similar businesses.

About Your Business
Important: These calculators and checklists provide educational estimates and general information only, based on the figures you enter and simplified, commonly used calculation methods. They do not constitute financial advice, a quote, a recommendation, or a guarantee of any insurer's terms, underwriting decision, settlement methodology, or tax treatment. Actual available cover, premiums, discounts, policy limits and Insurance Premium Tax rates are set by individual insurers and the Government respectively, vary between providers, and may differ from these illustrations. The business insurance checklist identifies cover types commonly considered by businesses with similar characteristics; it does not assess your specific circumstances or recommend any insurer or policy. Always check individual policy documents and current published rates, and consider speaking with a regulated financial adviser or insurance broker for personal recommendations.

Frequently Asked Questions

Are these insurance calculators free to use?

Yes, all calculators on this page are free to use and do not require any personal details, an account, or a quote request.

Do these calculators provide an actual insurance quote?

No, these are educational estimating tools only. They provide a starting point for your own planning and research, not a binding quote or financial advice from an insurer or adviser.

How accurate is the life insurance cover calculator?

The calculator applies two commonly used estimation methods, the income multiplier and needs-based approaches, based on the figures you enter. Accuracy depends entirely on the accuracy of your own inputs and individual circumstances not captured by a simplified calculation.

Should I use the buildings rebuild cost or market value for home insurance?

Buildings insurance should be based on rebuild cost, which reflects the cost of rebuilding your home from scratch, not its market sale value. These two figures are often very different.

How is the income protection benefit calculator worked out?

It applies a replacement percentage, typically 50 to 65 percent, to your gross annual income to estimate a monthly benefit, then optionally offsets any existing sick pay or benefits you enter. Actual available cover depends on insurer underwriting, occupation and health, not just income.

How does the IPT calculator work out the tax included in my premium?

It treats your quoted premium as already including Insurance Premium Tax, then works backwards using the standard 12% or higher 20% rate to show the underlying premium and the tax amount separately, based on the current rates verified in our Insurance Premium Tax guide.

How does the GAP insurance calculator work out the shortfall?

It subtracts an estimated market value from the amount you'd want covered if your car were written off, such as the purchase price or outstanding finance settlement, to show an illustrative shortfall. It is not a valuation or a quote, and actual insurer settlement methodology varies by provider.

Does the no claims bonus calculator use a specific insurer's discount scale?

No. It uses only the premium and discount percentage you enter, which you can find on your renewal documents, because no claims bonus scales vary significantly between insurers and ShopTera does not assume any particular provider's scale.

How is the annual vs single-trip travel insurance comparison calculated?

It multiplies the number of trips you enter by your typical single-trip policy cost, then compares that total against an annual multi-trip premium you enter, showing which option works out cheaper based on your own figures.

What figure does the valuables limit checker use if I don't know my policy's limit?

If no limit is entered, it uses £1,500 as a reference point, the single article limit used in the worked case study in our Jewellery and Valuables Insurance guide. This is an illustrative example only, not a typical or universal limit, and actual limits vary by insurer and policy.

Does the business insurance checklist recommend specific insurance products?

No. It provides general information about insurance types commonly considered by businesses with similar characteristics to those you select, and clearly distinguishes any legal requirement from commonly considered options. It does not name or recommend any specific insurer or policy, and is not a substitute for professional advice.
