Last Hearing Aid UK Update: 30
LE Audio, part of the new Bluetooth 5.2 and 5.3 standards, is a low-power version of Bluetooth specifically designed for streaming audio.
This technology is particularly relevant in the UK, where the Equality Act 2010 requires public venues to make reasonable adjustments for people with disabilities. For venues, that is good news. Auracast does not require a costly overhaul of existing infrastructure — it can be added relatively simply, making it a genuinely practical route to better accessibility for a wide range of spaces.
Built into Bluetooth LE Audio is Auracast — a feature that lets a single audio source broadcast to an unlimited number of receivers at once, whether that's Bluetooth earbuds, hearing aids, or other compatible devices.
It's also designed with efficiency in mind, using low energy consumption to help extend battery life. And when it comes to connecting and customising your devices, the whole process is noticeably more straightforward — making it easier to personalise how you hear.
Bluetooth, introduced in 1999, was created for high-bandwidth wireless data transfer, including audio streaming, though that wasn’t its main purpose.
In contrast, when looking deeper into the technology, LE Audio uses the LC3 (Low Complexity Communication Codec). This means there's a wider range of bit rates and unlimited channels.
From a hearing health perspective, the improvements are meaningful. Built-in hearing aid support and a more seamless, flexible experience make Bluetooth LE Audio genuinely more accessible than classic Bluetooth — and that's a big deal for the millions of people who depend on their devices to hear clearly every day.
Put simply, bit rate determines how much audio information travels per second — more of it means better sound. But Auracast and LE Audio don't just improve on classic Bluetooth in that one area; they also reduce latency and use power more efficiently.
Classic Bluetooth holds up fine, but LE Audio is a genuine step up. A lot of that comes down to the LC3 codec we touched on earlier, which handles audio in a smarter, more efficient way.
With Auracast, you can connect to the TV's audio and stream it directly to your headphones or hearing aids, so there's no struggling to hear over the background noise.
LE Audio allows hearing aid wearers, within range of a compatible transmitter, to connect to Auracast broadcasts with the press of a button or via an app. This technology not only improves audio quality but also reduces power consumption, enabling developers to add more features without affecting battery life.
In the UK market, Auracast-enabled hearing aids are now available from most major manufacturers. Audiologists are also now beginning to recommend Auracast-enabled devices for patients who regularly attend theatres, concerts, or places of worship, as early adopter venues start to install this technology.
The good news for anyone considering new hearing aids is that Auracast is already here. It is built into the latest devices from most major manufacturers, and the expectation is that it will become standard across the board within the next few years.
For people with hearing loss, that means clearer sound, less background noise, and a genuinely more connected experience — in everyday life and in the public spaces that have historically been the hardest to navigate.
As with any technology, Auracast isn't without its limitations. The most immediate is compatibility — older devices simply won't support it, which means some users will need to upgrade to take advantage of it.
For those on NHS hearing aids, the wait is likely to be longer. NHS devices tend to run a generation or two behind the latest commercial models, so widespread Auracast access through that route is still some way off. Private hearing aid users, on the other hand, are already beginning to see Auracast-enabled options becoming available.
Industry bodies and accessibility organisations have emphasised the importance of maintaining traditional induction loop systems alongside Auracast during the transition period.
With around 18 million people in the UK living with hearing loss — according to RNID's 2024 figures — the potential impact of Auracast is enormous. But it is worth being realistic.
Not everyone will have access to compatible devices straight away, and for many, particularly those on NHS hearing aids, it may be some years before Auracast becomes part of their everyday experience.
Private hearing aid users will have earlier access to Auracast-enabled devices, though many UK private providers offer flexible upgrade programmes and trial periods to help patients access the latest technology.
While Auracast is designed for low power consumption, some devices might still experience higher battery drain during extensive use.
Security could also be a problem, as the ability to broadcast to multiple devices might raise privacy issues if not properly managed. For more detailed information on Auracast, visit here
UK theatres appear to be among the early adopters of Auracast, with a number of venues already running trials or having made confirmed installations.
Among the confirmed UK venues are Manchester's Contact Theatre and Cheltenham's Everyman Theatre, which were among the first to install the technology, followed by the National Theatre's Dorfman — where a trial ran during Man and Boy in early 2026 — and the Bridge Theatre in London, which has also completed a trial.
Beyond theatres, Bristol Temple Meads became the first UK railway station to switch on Auracast in July 2025, with Ampetronic's Auri system installed across platforms, the ticket hall and the pedestrian subway. The Hippodrome in Birmingham is also confirmed as an early UK adopter.
In December 2025, a significant moment for the UK rollout came when major venues — including Shakespeare's Globe, the National Theatre, and the Southbank Centre — joined hearing care professionals and technology companies in publicly committing to working towards an Auracast-enabled future by 2030.
The statement called on arts venues, transport hubs, hospitals and supermarkets to get ahead of the curve and make equal participation the standard in every space.
Wider rollout across public spaces is still developing, but the momentum is real and building quickly. Globally, industry forecasts point to around 1.5 million public venues offering Auracast by 2029 — though no specific targets for the UK have been made public yet.
For UK hearing aid users considering an upgrade, Auracast compatibility is worth including in your requirements if you regularly attend theatres, concerts, or places of worship. Whilst the infrastructure is still developing, venues are beginning to install transmitters, and early adopters will benefit as more locations come online.

How long do hearing aids last?
Parts of a hearing aid
What hearing aid features do I actually need? Do not spend hundreds of pounds without getting a second opinion from us.
Not only are the prices great, but the service is fantastic! Many thanks to your team.In general, any audiologist will always recommend to you the hearing aid model that best suits your needs. Here is a useful checklist to make sure that is the case.
If you have significant hearing loss in both ears, you should be wearing two hearing aids. Here are the audiological reasons why:
Localisation: The brain decodes information from both ears and compares and contrasts them. By analysing the minuscule time delays as well as the difference in the loudness of each sound reaching the ears, the person is able to accurately locate a sound source.
Simply put, if you have better hearing on one side than the other, you can't accurately tell what direction sounds are coming from.
Less amplification is required: A phenomenon known as “binaural summation” means that the hearing aids can be set at a lower and more natural volume setting than if you wore only one hearing aid.
Head shadow effect: High frequencies, the part of your hearing that gives clarity and meaning to speech sounds, cannot bend around your head. Only low frequencies can. Therefore, if someone is talking on your unaided side, you are likely to hear that they are speaking, but be unable to tell what they have said.
Noise reduction: The brain has its own built-in noise reduction, which is only really effective when it is receiving information from both ears. If only one ear is aided, even with the best hearing aid in the world, it will be difficult for you to hear in background noise as your brain is trying to retain all of the sounds (including background noise) rather than filtering them out.
Sound quality: We are designed to hear in stereo. Only hearing from one side sounds a lot less natural to us.

For most people, the main benefit of a rechargeable hearing aid is simple convenience. We are used to plugging in our phones and other devices overnight for them to charge up. Here are some other pros and cons:
For anybody with poor dexterity or issues with their fingers, having a rechargeable aid makes a huge difference, as normal hearing aid batteries are quite small and some people find them fiddly to change.
One downside is that if you forget to charge your hearing aid, then it is a problem that can't be instantly fixed. For most, a 30-minute charge will get you at least two or three hours of hearing, but if you are the type of person who is likely to forget to plug them in regularly, then you're probably better off with standard batteries.
Rechargeable aids are also a little bit bigger and are only available in Behind-the-Ear models.
Finally, just like with a mobile phone, the amount of charge you get on day one is not going to be the same as you get a few years down the line. Be sure to ask what the policy is with the manufacturer's warranty when it comes to replacing the battery.
For most people, the answer is yes. But it's never that simple.
The majority of hearing problems affect the high frequencies a lot more than the low ones. Therefore, open fitting hearing aids sound a lot more natural and ones that block your ears up can make your own voice sound like you are talking with your head in a bucket. Therefore, in-ear aids tend to be less natural.
However, the true answer is we can't tell until we have had a look in your ears to assess the size of your ear canal, and until we have tested your hearing to see which frequencies are being affected.
People with wider ear canals tend to have more flexibility, also there are open fitting modular CIC hearing aids now that do not block your ears.
There is also the age-old rule to consider, that a hearing aid will not help you if it's sat in the drawer gathering dust. If the only hearing aid you would be happy wearing is one that people can't see, then that's what you should get.
Most people can adapt to any type of hearing aid, as long as they know what to expect. Have an honest conversation with your audiologist as to what your needs are.
Generally speaking, six or more. Unless it's none at all. The number of channels a hearing aid has is often a simplistic way an audiologist will use to explain why one hearing aid is better than another, but channels are complex, and it is really not that straightforward. Here are some reasons why:
Hearing aids amplify sounds of different frequencies by different amounts. Most people have lost more high frequencies than low, and therefore need more amplification in the high frequencies. The range of sounds you hear is split into frequency bands or channels, and the hearing aids are set to provide the right amount of hearing at each frequency level.
Less than six channels, and this cannot be done with much accuracy, so six is the magic number. However, a six-channel aid is typically very basic with few other features and is suitable only for hearing a single speaker in a quiet room. The number of channels is not what you should be looking at; it's more the rest of the technology that comes with them.
As a final note, different manufacturers have different approaches. One method is not necessarily better than any other. For example, some manufacturers have as many as 64 channels in their top aids. Most tend to have between 17 and 20. One manufacturer has no channels at all.
Manufacturer's warranties typically last between 2-5 years, depending on the brand and model, and cover defects in materials and workmanship. This includes repairs for component failures, electronic malfunctions, and manufacturing defects, but excludes damage from misuse, accidents, or normal wear. Most manufacturers also include loss and damage insurance for the first year.
We handle all warranty claims on your behalf, liaising with manufacturers and ensuring you get replacement devices quickly when needed. This comprehensive warranty coverage, combined with our lifetime aftercare, gives you complete peace of mind. Find out more about our warranty cover here
Our hearing tests are completely free, whether at our clinics or in your home. Unlike other providers who charge £30-£100 for home visits, we believe hearing healthcare should be accessible without financial barriers. Our comprehensive assessments include examination by an HCPC-registered audiologist, audiogram results, and personalised recommendations.
All testing, future adjustments, and ongoing support are included at no extra cost. While NHS tests are also free, typical 6-week waiting periods often lead people to seek immediate private testing. We provide prompt, professional assessments that fit your schedule and budget.
Yes, we offer completely free home visits throughout the UK, and this service is included in our prices with no additional charges. Home visits are particularly valuable for people with mobility issues, busy schedules, or those who simply prefer the comfort and convenience of their own environment.
Our audiologists can conduct full hearing tests, fit hearing aids, and provide ongoing support in your home. This service sets us apart from many providers who either don't offer home visits or charge extra for them.
We can offer prices up to 40% lower than high street retailers because of our business model. As a network of 200+ independent audiologists, we don't have the massive overheads of large retail chains - no expensive high street premises, no sales targets pushing audiologists to sell the most expensive options, and no costly marketing campaigns.
However, we maintain the same buying power as the big chains because we purchase on behalf of our entire nationwide network. This means you get access to the same premium hearing aids with professional service, but at genuinely competitive prices.
We offer a comprehensive 60-day money-back guarantee, which gives you twice the industry standard time to properly assess whether your hearing aids are right for you. This extended period recognises that adjusting to hearing aids takes time, and your brain needs several weeks to adapt to the amplified sounds.
Unlike many providers who offer just 30 days, we believe 60 days gives you the confidence to test your hearing aids in all the situations that matter to you - from quiet conversations at home to busy restaurants and outdoor activities.
