Key Takeaway

October is the busiest month for UK home insurance renewals. You can reduce your premium by increasing your voluntary excess, installing approved security devices, bundling buildings and contents cover, paying annually rather than monthly, and ensuring your cover details accurately reflect your current circumstances. Small changes can save you £50 to £200 or more each year.

Why October Matters for Home Insurance

October sees the highest concentration of home insurance renewals across the UK. Many homeowners took out policies in autumn when moving house or remortgaging, creating a seasonal spike. Insurers know this and often raise renewal premiums, counting on customer inertia. According to the Association of British Insurers, comparing quotes and actively managing your policy can deliver significant savings (ABI, 2026).

The principle of careful household management, as explored in foundational texts such as Thrift, remains relevant today: small, deliberate choices around financial commitments compound into meaningful savings over time.

Below are five practical ways to cut your premium without leaving yourself underinsured.

1. Increase Your Voluntary Excess

Your excess is the amount you pay towards any claim before your insurer covers the rest. Policies carry a compulsory excess set by the insurer, plus an optional voluntary excess you can add.

Raising your voluntary excess from £0 to £250 or £500 signals to the insurer that you are less likely to claim for minor incidents. This reduces their expected payout and can lower your premium by 10% to 20%, depending on the insurer and your circumstances.

Important: only choose an excess you can afford to pay in full if you need to claim. Setting it too high to save on the premium leaves you financially exposed after an incident such as a burst pipe or a break-in.

2. Install Approved Home Security

Insurers reward properties with effective security. Fitting a burglar alarm, secure locks, or a monitoring system approved by recognised standards (such as those certified to British Standards or by the National Security Inspectorate) demonstrates lower theft risk.

MoneyHelper notes that home security improvements can reduce premiums, particularly for contents insurance (MoneyHelper, 2026). Before investing, ask your insurer which specific devices they recognise and how much you might save. Installation and monitoring costs should be weighed against the annual premium reduction.

Window locks, a five-lever mortice deadlock on external doors, and visible alarm boxes are among the most cost-effective measures. Some insurers also offer discounts for belonging to a Neighbourhood Watch scheme.

3. Bundle Buildings and Contents Cover

Taking out buildings insurance and contents insurance as a combined policy with the same provider is almost always cheaper than buying them separately. Insurers apply a discount because bundling reduces their administration and increases customer retention.

Which? research confirms that combined policies typically cost less than two standalone products, and they simplify renewals and claims (Which?, 2026). You deal with one renewal date, one set of paperwork, and one insurer if you need to claim.

If you currently hold separate policies with different providers, compare combined quotes at renewal. Even if your existing buildings insurer offers good value, a competitor’s combined deal may beat your total cost across both policies.

4. Pay Annually Instead of Monthly

Spreading your premium over 12 monthly instalments is convenient but expensive. Insurers treat monthly payments as a form of credit and charge interest, typically adding 10% to 20% to the total annual cost.

Paying the full premium upfront eliminates this interest charge. For a £400 annual premium, paying monthly at 15% APR would cost around £460 over the year. Paying the lump sum in October saves you £60.

If cash flow is tight, consider setting aside a small amount each month into a separate savings account so the annual payment is manageable when October arrives. The interest you earn, even at modest savings rates, works in your favour rather than the insurer’s.

5. Review and Update Your Cover Details

Premiums are calculated using the information you provide about your property and circumstances. Outdated or inaccurate details can inflate your cost or, worse, invalidate your cover when you claim.

Check the following at renewal and update any changes:

  • Rebuild cost: buildings insurance should cover the full cost of rebuilding your home (not its market value). Use the Association of British Insurers’ rebuild cost calculator to get an accurate figure. Overestimating wastes money on unnecessary cover; underestimating leaves you short if the property is destroyed.
  • Contents value: list your possessions and tot up their new-for-old replacement cost. Remove items you no longer own and add new purchases. Over-insuring increases your premium for no benefit.
  • Security and occupancy: tell your insurer if you have installed new locks, an alarm, or if the property is now occupied differently (such as becoming your main residence rather than a second home).
  • No claims: confirm your insurer has recorded any no-claims period correctly. Some providers apply a discount after one or more claim-free years.

Providing accurate, current information ensures you pay for the cover you actually need and protects your right to claim.

Frequently Asked Questions

Will comparing quotes damage my credit score?
No. Insurance comparison sites perform soft searches that do not appear on your credit file or affect your score. Only applying for credit-based products (such as monthly payment plans) triggers a hard search.

Can I switch mid-year if I find a cheaper quote now?
Yes, but your current insurer may charge a cancellation fee and recalculate your refund, sometimes leaving you out of pocket. Switching is usually most cost-effective at renewal, though if the saving is large enough it may justify the fee.

Do I need buildings insurance if I own a flat?
Buildings insurance is typically arranged by the freeholder or management company and charged through your service charge. Check your lease and service charge breakdown. You are responsible for contents insurance.

What if I cannot afford the excess I set last year?
Contact your insurer before renewal and lower your voluntary excess. Your premium will increase, but you avoid being unable to claim because you cannot pay the excess.

Conclusion

October renewal season is the ideal moment to review your home insurance and make changes that reduce your premium. Increasing your excess, improving security, bundling cover, paying annually, and updating your policy details are all proven strategies that can cut costs without compromising protection.
