Energy providers are struggling to keep up with the demand from Scots eager to log meter readings ahead of a 54% rise in the energy price cap.
The websites of firms including E.ON Next, SSE, Octopus Energy, British Gas, EDF Energy and Scottish Power have gone down as millions try to send meter readings covering their energy usage up to the end of March.
Consumer journalist Martin Lewis has urged customers to send meter readings to their energy company to avoid being overcharged for any gas and electricity used before regulator Ofgem increases the maximum price-cap.
