Nationwide changing T&C

budda79

I have had a mortgage with Nationwide for nearly 4 years and we took the mortgage out due to it offering a 12 month payment break, we went in to see if we could take a payment break as we are struggling with money at the moment and we were told that we could now only take a 12 month payment break if we were on maternity leave, but we could take 3 months at a 25% reduction due to the terms and conditions changing, due to the current climate.

Can the Nationwide do this as I believe that when we took out the mortgage with them it was a bidding contact and we agreed to the terms at the time we took out the mortgage.

Can anyone let me know if this the case and I can get my 12 month payment break without being on Maternity pay or if their new terms apply to us.
