best to call them and explain the circumstances you are in. They may not offer a holiday as such (especially if you havnt paid over) but with many people struggling at this time they may offer an interest only payment instead
call them asap before you get into further difficulties
Definitely call them. I am with the YBS but due to hubby being unemployed we have been allowed to take a payment holiday for 6 months even though we have never paid over. I am sure it states on their website you have to pay over as well. You won't know unless you ask!
