My understanding is (admittedly 2 or 3 years old):
- You have to be on some kind of enhanced mat pay to sign up and get vouchers
- once you're getting them then you're entitled to keep getting them
- your salary sacrifice is legally not related to your receipt of the vouchers
- You're legally entitled to keep receiving the vouchers as they're a benefit which all employees (with children?) are entitled to
- if you have a salary your employer will take the value of the vouchers out of your salary, with your consent
- If you only have SMP then your employer can't take any deductions out, but they have to keep giving you the vouchers
So basically if you want the vouchers for free you need to sign up while you're salaried (assuming you get enhance maternity pay, not just SMP)
I am not legal. This is what I gathered from googling though. I gather it's a loophole.
Unlike tax evasion / tax haven etc type loopholes which cost the gov billions per year this seems to be a fairly small one which not many people know about and lots of companies refuse to honour (even though legally they have to - but who is going to take them to court?!)

This link to the government's website clearly states:
Non-cash payments and contractual benefits
You may normally pay some of your employee’s earnings as a non-cash payment, for example, providing board and lodging or giving them goods or services. However, you must pay any SMP in full. SMP cannot be sacrificed or offset against other benefits, it must be paid in cash.
All non-pay contractual benefits must continue during statutory maternity leave. These may include any childcare vouchers, company car or mobile phone provided to the employee as part of their contract of employment.
