Autumn often brings a gradual rise in household spending. Energy use increases, insurance renewals approach and end-of-year expenses begin to appear.

A short financial review in August can help identify unnecessary costs before they become harder to manage.

1. Review Your Energy Tariff

For households on default tariffs paying by Direct Debit, the UK energy price cap rose by 13% from 1 July to 30 September 2026. Ofgem stresses that this is not a cap on the total bill: what you pay still depends on your actual energy use.

The typical annual cap level for this period is about €2,178 after conversion.

Check whether you are on a standard variable or fixed tariff, submit an up-to-date meter reading and compare available deals before heating use rises.

If paying bills is becoming difficult, contact the supplier early rather than waiting for arrears to build. Ofgem says suppliers must provide support when customers ask for help.

A summer boiler service can also prevent expensive surprises later in the year.

2. Make Your Savings Work Harder

Money sitting in an old savings account may be earning considerably less than newer products.

Compare easy-access accounts if you need the money for upcoming bills or seasonal spending. If you can leave savings untouched for a fixed period, a fixed-rate account may offer a better return.

Also check whether a tax-efficient savings account makes sense for you.

The important point is not to chase every short-lived rate change, but to make sure your cash is not sitting for months in an account that has quietly become uncompetitive.

3. Check Broadband and Mobile Costs

Telecom contracts are particularly easy to forget once the introductory period ends.

Ofcom says standalone broadband can typically cost around €8 less per month than broadband bundled with an unused landline. Switching has also become simpler through the One Touch Switch system.

For mobile plans, compare how much data you actually use with what you currently pay for.

Before switching, check:

broadband speed;

mobile coverage;

remaining contract length;

exit charges;

whether you still use every service included.

If you prefer your current provider, ask whether it can offer a cheaper tariff before leaving.

4. Check When Your Mortgage Deal Ends

If a fixed or discounted mortgage deal ends later this year or in early 2027, start reviewing your options now.

Without a new arrangement, borrowers usually move automatically to the lender’s Standard Variable Rate, which may be more expensive. MoneyHelper says you can begin talking to your lender around six months before your existing deal ends.

MoneyHelper’s mortgage specialists advise comparing the full cost of a new deal rather than focusing only on the advertised interest rate, including arrangement fees and any early repayment charges. They also recommend speaking to the lender early if future payments look difficult to manage.

This gives you more time to compare offers rather than accepting whatever is available at the last minute.

5. Prepare Home Insurance for Winter

The average combined UK home insurance premium reached roughly €448 between April and June 2026, rising from about €439 in the previous quarter.

Do not wait until storm season to discover gaps in your cover.

Check:

storm and flood protection;

the policy excess;

alternative accommodation cover;

emergency assistance;

whether recent renovations have changed the rebuilding cost.

Chris Bose, Director of General Insurance Policy at the Association of British Insurers, has emphasised that maintaining properties and dealing with issues such as leaking pipes, drains and nearby trees can help reduce the risk of costly weather-related damage.

Remember that insurers generally expect homes to be properly maintained.

6. Do Not Ignore Car Insurance Renewal

Auto-renewal is convenient, but it does not guarantee a competitive price.

If your policy expires within the next couple of months, start comparing offers around three to four weeks before renewal.

Make sure quotations use accurate information about your annual mileage, occupation, parking arrangements and additional drivers.

Check optional extras too. Breakdown assistance, legal expenses, replacement vehicle cover and windscreen protection can all increase the premium, so keep only what is genuinely useful.

Price matters, but the cheapest policy is poor value if the cover does not meet your needs.

7. Review Long-Term Family Planning

Autumn is also a good moment to deal with financial paperwork that is easy to postpone.

Review your will, life insurance and beneficiaries, especially after major life changes such as having children, buying a home, marriage or separation.

For UK residents aged 55 and over, Free Wills Month usually takes place in October and allows participating solicitors to prepare or update a simple will without the normal fee.

Life insurance should also reflect your current circumstances. The amount originally chosen years ago may no longer be appropriate if your mortgage, income or family responsibilities have changed.

Keep the Review Practical

You do not need to overhaul every part of your finances in one weekend.

Start with the bills that can change most quickly: energy, telecoms, mortgage and insurance. Then review savings and longer-term planning.
