Commenting on the price rises, Hannah Maundrell, Editor in Chief of money.co.uk, said:

"I'm not joking, it really is National Price Hike Day as the cost of everyday activities is going up left right and centre. From postage to prescription and dental costs, your wallet is going to be hit left, right and centre. These hikes may appear to be small and 'nothing to worry about', but add them all together and it could cost you around £90 extra over the next year.

"While you can't avoid some of the increases, you can certainly take control when it comes to managing the cost of your energy, phone and broadband. We've got the bumpy Brexit ride ahead of us, with no idea what the future holds. The more money you can keep in your pocket and not pass on to suppliers the better. Why should you pay more for something you can get far cheaper elsewhere?"

Notes: 1. £88.00 (rounded up to £90) per year is calculated by taking a snapshot of key household outgoings, calculating the sum of price rises. £1,663,200,000 was derived by multiplying £88.00 by 18.9m. In 2016 there were 18.9 families in the UK (ONS) 2. Each band of dental treatment includes the following; * Band 1 is check-ups, scale and polish, diagnosis and treatment planning, marginal corrections of fillings, braces etc. * Band 2 is additional treatment, such as fillings, root canal treatment and removing teeth. * Band 3 is more complex procedures, such as crowns, dentures and bridges. 3. The cost of stamps increased on the 27th March 2017. 4. The date at which these price hikes take effect depends on the billing date for each individual customer but most will land between March and April.
