Will I have to make a new boiler finance deposit?

It’s all up to you. You can choose to pay nothing or pay 50% of the loan amount. It must be stated that a minimum loan of £1,000 is needed.

A large deposit of 50% can reduce your monthly repayments, cutting the cost down to a trivial £10 a month.

With that in mind, choosing a monthly payment plan probably means that you don’t have a large sum of money on hand. And that’s the whole point for the paying monthly scheme.
