But read the note referenced:

4.2.3 Producers sharing premises and equipment

Regulation 8A of the Biofuels and Other Fuel Substitutes (Payment of Excise Duties etc) (Amendment) Regulations 2007 (SI 1234 of 2007) which came into force on 30 June 2007, has a condition that separate producers at the same premises or sets of premises must register and account for duty if the total of that production is 2,500 litres or more a year. The threshold does not apply separately to each individual producer at the same premises - or sets of premises. The producer(s) must register if total annual production at the same premises or sets of premises is 2,500 litres or more.

Partnerships, collectives and cooperatives (including non-profit making organisations) are liable to register and account for duty if total annual production is 2,500 litres or more.

So the way I read it is that if you are a user ie: buying it, then you and the mrs each have 2500ltr.
If you are producing it ie: making bio, or filtering WVO for you AND the Mrs, then the premises has a 2500ltr limit in total.
