Citizens Advice has said an extra room "can be a lifeline" for a disabled person, calling it "as vital as a guide dog or a wheelchair".
Chief executive Gillian Guy said for many people a spare room "is essential to their wellbeing" as it is needed for dialysis equipment or room for a carer.
Ms Guy said: "Many sick and disabled people have bedrooms which have been adapted to help them to cope with their condition.
"Moving disabled people out of their houses is not only a potential risk to their health, but can cost the individuals affected and councils significant amounts of money if they need to start from scratch in a new home."
Citizens Advice has welcomed the Chancellor's proposals on pensions in his Budget speech.
Citizens Advice chief executive Gillian Guy said after the announcement: “The proposals to free up pensions are welcome, particularly the new ‘right to advice’, which recognises the significant value of impartial, trusted advice.
“People who are able to put money aside into savings will find an increase in how much they can save tax free helpful.
"But the Chancellor does need to remember that for many people, saving money is a pipe dream as they are struggling to make ends meet."
The Citizens Advice Bureau has warned that the UK is "on the edge of a serious housing crisis" after releasing data on the increase in cases it has dealt with relating to rent arrears and threatened homelessness.
Social housing tenants are facing an increased threat of homelessness, the Citizen's Advice Bureau has warned, after cases of rent arrears cases reported to the charity rose 13 per cent from July to September this year.
Citizens Advice warned that despite growing confidence in the UK's economic recovery, households are not yet feeling the benefit of the improved economic outlook.
It suggested that the impact of the Under-Occupancy Penalty, combined with changes to Council Tax support, has contributed heavily to rent arrears problems
Instances of Citizens Advice Bureaux advising clients about Discretionary Housing Payments, to help people pay their rent, have more than doubled in the six months since April this year when the charge for under-occupancy was introduced.
Citizens Advice chief executive Gillian Guy has welcomed the proposed cap on payday loans but said that it was important to address the causes of the increase in their use:
The Government's plan to cap the cost of loans only goes to show how out of control the industry is ...
Government must also tackle the underlying need for payday loans and ask what is driving people to short-term credit in the first place.
– Gillian Guy, chief executive, citizens advice
New figures released by Citizens Advice found that three out of four borrowers find it difficult to repay payday loans, while 62 percent of loans still come without proper checks to assess whether borrowers can afford to repay.
EDF Energy's price increase has put the spotlight on the other big energy firms who have introduced much larger price hikes, according to the Citizens Advice Bureau.
The French-owned company are the latest member of the "big six" to raise their prices, however their increase of 3.9 per cent is significantly less than its rivals including British Gas and SSE.
“The price increase announcement from EDF today puts the spotlight on the other big energy firms who are introducing much larger price hikes. Many consumers will believe suppliers are putting profits before customers’ need to stay warm this winter," Chief Executive Gillian Guy said.
“People do not have the money to keep absorbing price rises. For many households the pot is quite literally empty. Families are facing tough choices, like cutting back on food in order to put the heating on for just a short while."
Figures released by the Citizens Advice Bureau last month showed that one quarter of parents are forced to borrow money to cover the cost of a new school uniform, as the Government urges schools to avoid branded uniforms in a bid to ease financial strain.
The charity's study also found:
72 percent of parents will be forced to buy uniforms from a specific shop;
Nine in 10 parents will buy a new uniform this year;
Nearly two-thirds of parents will pay more than £70 for a new uniform per child this term;
23 percent of parents don’t know how they will be able to pay for uniforms.
