I'm going to see what they offer and if needs be we will take a voucher and go to local indie providers.
After your extremely helpful advice previously I've already visited them. Ds has tried out models he'd like. They informed me I'd need to ask about voucher. I sold my car recently when ds got his motability vehicle and I've saved the funds with the leftover car payment to fund it privately if needs be.
We also have the option of paying a deposit and paying monthly if needed.
And I've just had my payrise confirmed and will be backdated to April in December pay so I'm set up to go whatever way is best for him.
