One of the regulars at the hub is 64-year-old Les Mifflin, a former kitchen porter who ended up homeless after the breakdown of a relationship.
Due to ill health he currently gets a PIP payment but if the changes come into force, he said he would face a significant cut.
"I will be impacted by what they are looking to do, that's my understanding of it," he said.
"That will make life a lot harder for me – the cost of everything is going up so I can't afford them to cut it.
"I can't work due to my health, I'm a diabetic too.
"I've been coming here for around seven months; I feel safe here but I don't feel safe by what the government wants to do."
The hub has had 5,000 visits since they opened with the list of regulars rising from 220 people in the winter to about 280 now.
The centre exists largely on donations and is currently fundraising to try and expand its offer.
Zena, 35, is a single mum who described the hub as a "lifeline" for people who are struggling.
"It's a real relief, actually, to have somewhere like this in the community where you get welcomed in," she said.
"I'm not a very sociable person but when I come here I know there is help available if I need it."
Ministers want to save £4.8bn by reducing the benefits bill with a consultation set to run into June.
Overall the government estimates 3.2 million families will be worse off as a result of the reforms by 2030 while 3.8 million families will be better off.
The DWP spokesperson said: "We have been clear that protecting people in need is a principle we will never compromise on.
"The social security system will always be there for those with severe health conditions, and we will introduce a new premium for those who will never be able to work."
