I agree that you need to ask each uni for their preferred route.
If funding is an issue, then you need to be aware of the options and implications around Access, Foundation Years and Foundation Degrees.
For an Access course, you'd be eligible for a 24+ Advanced Learning Loan. If you then went on to complete a degree, that loan would be wiped out and you'd owe nothing for the Access course.
For a Foundation Year or Degree, you'd be funded by Student Finance. This would be the standard package of Tuition Fee Loan, Maintenance Loan and (depending on household income) Maintenance Grant. The loan elements would all be repayable.
A Foundation Degree will take two years and can be topped up to an Honours degree with a further year's study. A Foundation Year is usually attached to a specific degree course or group of courses, and is a preparatory year which readies you for the three year degree course afterwards. For a Foundation Degree+top up year, you'd owe three years's worth of SF. For a Foundation Year+three year degree, you'd owe four years of SF.
To summarise:
Access only route - four years of study, one effectively free if the degree is passed, three with repayable SF funding
Foundation degree - three years of study (four if they want an Access course for entry), with three years of repayable SF funding
Foundation year - four years of study (five if they want an Access course for entry) with four years of repayable SF funding
You probably won't get a choice where a uni expresses a preference, and Foundation years/degrees aren't available for every subject. But it's worth being aware of the pros and cons of each route before you start contacting unis.
