Help - landlord demanding back payment of rent, but I am paid in full

You paid 180 per month rather than 180 every 4 weeks so it looks to me as if you haven't paid in full and the landlord is within her rights to ask for the outstanding balance.

I'd say it's highly likely she was well aware of the fact that you were paying a bit less than she had stated but she was happy enough to have the place rented for the time being so she just left it at that and said nothing, fully intending to eventually use that as an excuse to keep all the deposit money.
If she was collecting the rent monthly, the rent amount should have been stated as x per month whereas if she stated it as x per week she should have collected weekly. And she should have said something much earlier if you were not paying enough rent, but I suppose technically if you were meant to paying more per week you do owe the money, but it's a bit ridiculous to expect you to pay all that in arrears at this point.
Instead of just avoiding her completely, apologize for the confusion and say if it had been brought up earlier you would have paid the full amount each month but that you've used up all your available money on the deposit and rent for your new place and don't have any money to give her and say you're going to be actually even more broke than you thought you were because you were counting on getting that 180 back. If she's too lazy or stupid to collect the full amount of rent for nine months she's hardly going to come after you in any legal way for the other 75 quid which is all you would owe anyway (765/3 = 255 - 180 =75). 180 quid is a good bit of money but it's not a huge amount, anyway it's gone now and you can't really try and get it back because you weren't paying full rent (even if you didn't mean to underpay).
Be sure and ask her why she didn't collect the rent weekly if she wanted x amount per week and why she didn't say anything for nine months, be interesting to see what she says. If she says 'Oh, I didn't notice'. just say 'Well neither did I. Very sorry." Don't give her a penny more even if she threatens some kind of action, she'll never follow through on it based on how she's been operating for the nine months.

Ok so originally the house was up for 135 weekly. 3 of us took the house but began nine months ago paying 180 each per month and there has never been a problem until yesterday I asked for my 180 deposit back. at first this was fine then i get a text and the landlord said that the other tenants had not paid there last months rent. She then said she had looked back and seen that she is owed 765 rent due to her calculating weekly and us monthly. I realise that the original price was 135 weekly but surely she cannot now ask for back payment of the difference as she has not brought it up all year. I don't know what to do here and wonder if she can do this having accepted the rent monthly from each of us all year. Please help as soon as possible as have to meet her in the morning thanks

When a number of people sign a single lease agreement for a property, as a single unit, they all become "jointly and severally" liable for the rent. This means that each tenant is collectively or individually liable for the rent. Thus the landlord may seek the rent from all the tenants, or in case of default of rent (i.e. rent arrears) from any one individual tenant.
