The heatwave has triggered a surge in prices for seasonal items, with the cost of one inflatable hot tub nearly doubling in a week, while an industry expert said air conditioning units had risen by about 17% since April.
The Guardian looked at popular items across a range of websites and examined their prices on PriceRunner, an independent price comparison service. One of the biggest price increases was for the Bestway inflatable hot tub Lay-Z-Spa Cancún AirJet, which was available for £160 on 21 May but now retails for a minimum of £299.
