Prices start at £30 for a two-day service, though a faster turnaround may be possible, depending on demand.
A spokesperson said: ‘If you’ve cleaned your lenses, but you’re still seeing dark spots and marks on your images, it’s time to get your sensor cleaned.
‘Jessops’ service will help to keep your camera in top condition by cleaning the dirt and dust from the sensor…’
A full camera clean – which includes the LCD, viewfinder and lens – costs an additional £10.
