Halloween can be an expensive time of year, with new spooky costumes, sweets, party decorations, make-up, accessories, experiences and much more.

And as the cost-of-living crisis continues to be a big concern for families, many are cutting back on how much they spend due to the rise in energy bills and interest rates.

But there is still a way to have the best and most terrifying Halloween without breaking the bank.

From getting creative and doing some Halloween crafts over the half term, swapping the Halloween party to trick or treating and maybe even trying your hand at baking, there are plenty of budget-friendly themed activities to do over Halloween.
