Not sure how it would work in the UK, but you can do it in a country like Denmark, but you'd need to split the time in two. You're legally required to provide 25 days, and for that to make sense financially, the company needs to keep track of the first 25 days as these are "earned" at a rate of 2,3 per month (something like that). Beyond the 25 days, you can grants as many "ferie-fri" (vacation/time-off)-days as you like. Technically the company can tell you when to use those, normally between Christmas and New Years, but they can waive that right and let employees decide for themselves. If you don't use your time, you can lose it, after a 1.5 years for the first 25 and a year for the rest. So I don't think it would be an issue in the UK either, but the company needs to do the accounting right.
