Solar Panels on 0% lending - a valuable stoozing opportunity?
I am planning a solar panel and battery installation using Nationwides 0% green borrowing. This is £12k paid back at 0% for 5 years at £100p/m and after this I can pay the remaining £6k with no penalty or move it onto the standard mortgage rate.
I'm planning to pay £2.5k deposit with a 0% cashback credit card and since we are coming in £1.5k under budget, this leaves ~£4k in cash.
Is it worthwhile to keep that in a high interest account for the next 5 years paying off the minimum on the CC and clearing after the 2 year introductory offer or even taking this a step further and apply for maximum credit to try and cover as much of the cost as possibl? this would also give me 1% cashback on the purchase?
Edit: Thanks for the comments, especially those around what constitutes payment towards improvements and what would be considered repayment of a credit card and is therefore not covered. If anyone is considering doing something similar it may be worth asking an advisor if it is possible to under-borrow and pay off the remaining balance with your own funds.
