Yes. Generally all shops that charge will have a blanket policy regardless of the type of card. Some stores (e.g. Aldi and Lidl) previously only accepted debit cards, although they now take credit cards too.
Things are different on the internet or paying government departments (e.g. DVLA for paying vehicle excise duty) where there tend to be no surcharge for debit cards but 2% usually on credit cards.
