As a deaf person you can apply for Personal Independence Payment (PIP). It is not automatically given as you have to give good reasons as to why you should be entitled to it.
if wanting to find out more, then I would suggest looking on Deaf PIP groups online that can advise how to apply and what things to put down.
if you are working you can apply for Access to Work to do an assessment of your needs to consider what support can be put into place at work to best support you in your job. For example this may provide you with a loop to use at work.
You can apply for NOW bus pass to use on buses.
You can apply for concessions rates to places such as cinemas/tourist attractions. For example if you are a National Trust member you can apply for a carer’s card which enables you to take someone in for free with you to provide support.
A lot of deaf people tend to downplay their disability as so used to being told to just get on with it.
Deaf people often suffer from concentration fatigue which leaves them very tired at end of day from all the listening/lipreading. This can also impacts on their mental and physical health.
What kind of things can you say impact you as a deaf person? Here are a few…
Not being able to follow conversation clearly. Often having to guess what is said or getting others to repeat. Usually they miss bits out or tell you “oh it doesn’t matter, wasn’t that important.”
Not being able to hear announcements in public places. Good example is a tannoy announcing train is now departing from a different platform. Most deaf people aren’t going to hear that and end up having to ask others what has just been said.
Difficulties with using telephone especially if lots of background noises or a difficult accent.
Difficulties with following conversation in noisy situations or struggling to lipread/understand difficult accent/beards/facial/tongue piercings/masks obstructing the face. Makes situations like hospital appointments more stressful.
Not being able to hear danger sounds such as car approaching fast/alarms going off. This increases more when tired/not able to wear hearing aid/implant.
At home risk of danger such as fire increases if cannot hear alarm at night or if in shower. Did you know specialist equipments for the deaf is way more expensive than your bog standard smoke alarm, and not all councils provide it for free either?
In response to the OP yes being deaf is a disability even though often people play down the impacts of it.
