Think it through

Questions to ask before you borrow, with links to MoneyHelper.

A clear picture of the cost.
Give yourself space to compare the full installation cost and how you would pay for it.

If you consider borrowing, compare the APR, repayment term, fees and total amount repayable. A smaller monthly payment can spread the cost over a longer period.
Check grant eligibility separately and make sure your installation quote clearly sets out what is included.
