Household bills and expenses continue to surge, despite a fall in overall inflation, the latest MSE Bills Tracker shows.

Average overall costs are up 1.7% over the 12 months to April 2018 - a 0.3% percentage point rise compared to March's 12-month figure.

This compares to a 0.1 percentage point drop in the headline CPIH inflation figure – more on which is below – from 2.3% to 2.2% between March and April, showing that inflation is slowing as bills and expenses growth continues to rise.

Travel insurance showed the sharpest price rise with an increase of 13.2% over the 12 months to April, compared to 6.2% in March. However, despite a general increase in insurance prices, car insurance dropped by 1.3% following a 1.7% increase in March. Regardless of price changes, many will still be paying over the odds - see our Travel Insurance and Car Insurance guides for information on how to cut costs.

Other rises shown by our Bills Tracker include a 4.9% increase in council tax in the 12 months to April, compared to 3.8% in March. Water bills are also up by 2.7% over the last 12 months, compared to 1.8% in March.

Our tracker, which launched in August 2017, 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 outgoings.

Here are some of the main 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 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 inflation measure, 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 April's MSE Bills Tracker show?

The MSE Bills Tracker shows that overall household bills and expenses were up 1.7% over the 12 months to April, up from 1.4% in the same period to March.

The graph below shows how the Bills Tracker has compared with CPIH since November 2016:

How the cost of different bills changed in April

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 April 2018, these increased by 0.4% and 1.2%.
  • Water costs. These include water supply and sewerage collection charges. For the 12 months to April 2018, these increased by 2.7%.
  • Energy costs. These include electricity and gas, and other fuels such as natural gas, kerosene and coal. For the 12 months to April 2018, these increased by 5.8%.
  • 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 April 2018, this increased by 4.9%.
  • Fuel. Including diesel and petrol. For the 12 months to April 2018, diesel increased by 3.5% and petrol increased by 2.8%.
  • Phone and internet costs. These include landline, mobile phone (handset and charges) and internet. For the 12 months to April 2018, these increased by 0.9%.
  • TV licence and subscriptions. These include TV licence costs and digital TV subscriptions. For the 12 months to April 2018, these increased by 2.9%.
  • Insurance. Including contents, health, travel and car insurance. For the 12 months to April 2018, car insurance decreased by 1.3%, while contents insurance increased by 8.7%, travel insurance by 13.2%, and other insurance, eg, health insurance, by 4.7%. The overall increase for insurance was 3.6%.
  • 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 April 2018, these decreased by 2.8%.

How can I use this info to save money?
