Household bills and expenses are continuing to rise, as this month's MSE Bills Tracker shows an overall increase in costs for the average home of 2.4%.

Our tracker, which launched in August, uses data supplied by the Office for National Statistics (ONS) to create a picture of the average price changes for household bills across the UK.

Inflation is usually measured by looking at the prices of hundreds of different items, but crucially our tracker cuts most of these out and focuses only on core expenses such as housing costs, energy and insurance – expenses which most households have and which typically make up the lion's share of your outgoings.

Petrol and diesel costs have risen by 6.3% and 6% respectively in the 12 months to September 2017, while insurance costs have jumped 7.4% year-on-year, with car insurance rising a whopping 12.9%. Here are some of the key figures – you can see a more detailed breakdown below:

How does MSE's Bills Tracker work?

Inflation is the rate at which the cost of goods and services bought by households rises or falls. The ONS publishes different measures of inflation, and we've requested specific data to come up with a realistic figure for the average change in a typical household's core outgoings.

Our figure uses elements of CPIH (which stands for – deep breath – the Consumer Prices Index including owner occupiers' Housing costs) – the most comprehensive measure of inflation. CPIH looks at the prices of a 'basket' of 700 goods and services listed in the Consumer Prices Index (CPI), such as clothes, food and furniture – and then adds costs associated with owning or renting a home.

Crucially, MSE's Bills Tracker cuts down the CPIH basket of goods and services to about 40 costs which many typical households are likely to face every month (see the list below).

We've focused on bills rather than expenses such as food, and stripped out items included in the CPIH that you're unlikely to buy often, if at all, such as rugs, door handles, a ten-pin bowling session and knitting wool. In other words, this is designed to be a real bills index reflecting typical household costs.

What does September's MSE Bills Tracker show?

The MSE Bills Tracker shows that overall household bills and expenses were up 2.4% year-on-year, the same rise we saw in August.

This is despite an increase in the value of CPIH from August to September – though that doesn't mean that bills aren't still rising, so you should always check you're getting the best deals you can.

The graph below shows how the Bills Tracker has compared with CPIH over the last 18 months:

How the cost of different bills changed in September

Here's a list of what's included in MSE's Bills Tracker, and how these costs have changed according to the most recent set of figures:

  • Rent and 'owner occupier housing costs'. These are measures of rental costs and the costs associated with owning a home such as a mortgage, maintenance and buildings insurance. The ONS measures these using something called 'rental equivalence', which estimates the amount homeowners would pay to rent their own home. For the 12 months to September 2017, these increased by 0.8% and 1.9%.
  • Water costs. These include water supply and sewerage collection charges. For the 12 months to September 2017, these increased by 1.8%.
  • Energy costs. These include electricity and gas, and other fuels such as natural gas, kerosene and coal. For the 12 months to September 2017, these increased by 5.2%.
  • Council tax. This is the average council tax bill in Great Britain and the average rates bill in Northern Ireland. For the 12 months to September 2017, this increased by 3.8%.
  • Fuel. Including diesel and petrol. For the 12 months to September 2017, diesel increased by 6% and petrol by 6.3%.
  • Phone and internet costs. These include landline, mobile phone (handset and charges) and internet. For the 12 months to September 2017, these increased by 2%.
  • TV licence and subscriptions. These include TV licence costs and digital TV subscriptions. For the 12 months to September 2017, these increased by 1%.
  • Insurance. Including contents, health, travel and car insurance. For the 12 months to September 2017, contents insurance increased by 2.4%, car insurance by 12.9%, travel insurance by 10.1% and other insurance, eg, health insurance, by 4.5%. The overall increase for insurance was 7.4%.
  • Other financial services costs. These include costs such as mortgage arrangement fees, bank charges such as overdraft fees, credit card fees and stockbrokers' fees. For the 12 months to September 2017, these decreased by 0.7%.
