Question 1

What is the best hearing aid model for me?

Accepted Answer

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.

Audiologist's level of knowledge: The audiologist you have seen will hopefully have a wide knowledge of all available hearing aids; however, some will only be familiar with a small number of brands and, therefore, may not really be in a position to know which model is the best for you. It is OK to challenge their recommendation and ask them to justify why this particular brand is the one for you.
Do research: Read about the hearing aid that was recommended. Does it seem like it will suit your lifestyle? Does it have more or fewer features than you need?
Be aware of sales targets: Many high street retailers have specific tie-ins to a particular manufacturer/brand. The hearing aid they have suggested may still be the correct one for you, but do your research so that you know why they might have recommended it.

Question 2

Do I need one hearing aid or two?

Accepted Answer

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.

Question 3

What are the benefits of rechargeable hearing aids?

Accepted Answer

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.

Question 4

Are Behind-the-Ear hearing aids better than In-the-Ear hearing aids?

Accepted Answer

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.

Question 5

What are channels, and how many do I need?

Accepted Answer

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.

Question 6

What's covered in a manufacturer's warranty?​

Accepted Answer

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

Question 7

How much does the hearing test cost?

Accepted Answer

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.

Question 8

Do you offer home visits, and are they included in the price?

Accepted Answer

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.

Question 9

Why are your hearing aids cheaper than what I'd pay on the high street?

Accepted Answer

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.

Question 10

How long do I have to try the hearing aids before committing to keep them?

Accepted Answer

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.

Question 11

Can I really buy hearing aids online without visiting a clinic first? Why can't I do this with your company?

Accepted Answer

While some companies do sell hearing aids online without professional involvement, we don't offer this service because we genuinely believe it's not in your best interests. Hearing aids aren't like buying glasses online - they require professional assessment, precise programming to your specific hearing loss pattern, and proper fitting to work effectively.

Through our network of over 200 qualified independent audiologists across the UK, we ensure you receive a proper hearing test, expert guidance on the right device for your needs, and professional fitting. This approach means you're far more likely to be satisfied with your hearing aids and actually use them regularly.

Question 12

What's the return policy if the hearing aids don't work for me?

Accepted Answer

Our return policy is straightforward and customer-friendly. You have a full 60 days from receiving your hearing aids to return them if you're not completely satisfied. There are no complicated procedures or attempts to talk you out of returning them - simply contact your local audiologist, and they'll arrange the return and process your full refund.

We believe that if the hearing aids aren't working for you after a proper trial period, you shouldn't be stuck with them. This policy reflects our confidence in both our products and our audiologists' expertise in finding the right solution for you.

Question 13

Are there any hidden costs for follow-up appointments or adjustments?

Accepted Answer

Absolutely not - transparency is fundamental to how we operate. When you see our published prices, everything you need is included: the hearing test, professional fitting, programming, and crucially, all aftercare and fine-tuning for the life of your hearing aids.

Many high street chains charge extra for follow-up appointments, but we believe ongoing support is essential for successful hearing aid use. The only additional cost you might encounter is batteries if you choose a non-rechargeable model, but even this is clearly explained upfront.

Question 14

Do you charge extra for maintenance visits or fine-tuning?

Accepted Answer

No, absolutely not. All maintenance, fine-tuning, adjustments, and ongoing support are included in your initial price and continue for the entire life of your hearing aids. This is quite different from many providers who charge for each visit after an initial period.

We believe that successful hearing aid use requires ongoing professional support, and charging extra for this would be counterproductive. Whether you need adjustments six months or three years after your initial fitting, there's no additional charge.

Question 15

How do I choose between all the different brands and models you offer?

Accepted Answer

This is where the expertise of our independent audiologists becomes invaluable. Unlike high street chains that are often tied to specific manufacturers, we're truly independent and have access to the full range of hearing aids from all major manufacturers. Your audiologist will assess your hearing loss pattern, lifestyle, dexterity, and personal preferences to recommend the most suitable options.

They're not working to sales targets or manufacturer incentives - their goal is finding the hearing aid that will work best for you, whether that's a basic model or the latest premium technology.

Question 16

Will the hearing aids I buy today become outdated quickly?

Accepted Answer

Hearing aid technology evolves gradually rather than dramatically, so a quality hearing aid purchased today should serve you well for many years. Most people keep their hearing aids for 5-7 years, and the technology we offer includes the latest features like artificial intelligence, advanced noise reduction, and smartphone connectivity.

More importantly, the fundamental job of a hearing aid - amplifying sound appropriately for your hearing loss - doesn't change with technology updates. We always recommend devices from current ranges rather than outdated models, ensuring you have access to the latest innovations.

Question 17

How do I know I'm getting the latest technology?

Accepted Answer

As independent audiologists with relationships across all major manufacturers, we have access to the newest hearing aid ranges as soon as they're released. We're not limited to older models or tied to specific manufacturers like some larger chains. When you visit one of our audiologists, they'll discuss the latest technology available and explain which features would benefit your specific situation.

Our website clearly indicates whether models are current, new launches, or superseded ranges, so you'll always know exactly what technology level you're considering.

Question 18

What happens if I need adjustments after I receive my hearing aids?

Accepted Answer

Adjustments are a normal and expected part of the hearing aid journey, which is why all follow-up care is included in our service. Your audiologist will typically schedule follow-up appointments within the first few weeks, but you can contact them anytime if you need adjustments.

Whether it's fine-tuning the sound levels, adjusting for comfort, or helping with new listening situations, your audiologist is there to support you throughout your 60-day trial period and beyond. This ongoing relationship is one of the key advantages of choosing professional care over online purchasing.

Question 19

Do you have audiologists in my area who can help me?

Accepted Answer

With over 200 independent audiologists across our network, we have coverage throughout the entire UK and Ireland. Our audiologists work from various locations - some have dedicated clinics, others work from day centres or shared premises, and all offer home visits when needed.

When you contact us, we'll connect you with your nearest HCPC-registered and qualified audiologist who can provide the same high standard of professional care regardless of location. This nationwide coverage ensures you're never far from expert support.

Question 20

What support do I get if problems arise with my hearing aids?

Accepted Answer

You have comprehensive support throughout the life of your hearing aids. During your 60-day trial period and beyond, you can contact your audiologist directly for any issues - whether technical problems, comfort concerns, or questions about use. All our audiologists are regulated by the Health and Care Professionals Council (HCPC), ensuring you receive professional support.

For warranty issues, we handle everything on your behalf with the manufacturer. This contrasts sharply with online-only providers, where you're often left to deal with problems yourself.

Question 21

How accurate are online hearing tests compared to clinic tests?

Accepted Answer

While online hearing tests can provide a basic indication of hearing issues, they're not a substitute for professional assessment. A qualified audiologist doesn't just test your hearing thresholds - they examine your ears, assess the type and degree of hearing loss, consider your lifestyle and communication needs, and can identify other ear health issues.

Online tests can't account for background noise, earphone quality, or properly controlled testing conditions. That's why we always include a comprehensive hearing assessment with one of our qualified audiologists as part of our service.

Question 22

What happens to my warranty and support if your company goes out of business?

Accepted Answer

Your manufacturer's warranty remains valid regardless of what happens to any retailer, as it's provided directly by the hearing aid manufacturer. However, Hearing Aid UK has been operating successfully with a network of established independent audiologists, many of whom have been in practice for decades.

Our business model is built on connecting you with local, established professionals rather than being a single company that could disappear. Your ongoing relationship is primarily with your local audiologist, who remains available to support you regardless of broader network changes.

Question 23

How do I know you're giving me unbiased advice and not just trying to sell me the most expensive option?

Accepted Answer

Our independence is key here. Unlike large chains that are often owned by or tied to specific manufacturers, we're truly independent with access to all brands and technology levels. Our audiologists aren't working to sales targets or manufacturer incentives - they're local professionals whose reputation depends on satisfied customers.

We publish all our prices transparently on our website, and our recommendations are based solely on your hearing needs, lifestyle, and budget. This independence, combined with our 60-day money-back guarantee, ensures you get honest advice rather than a sales pitch.

Question 24

Who handles repairs and maintenance for my hearing aids?

Accepted Answer

Your local audiologist handles all aspects of hearing aid care, from routine maintenance to coordinating warranty repairs. They can often resolve minor issues immediately during appointments, and for manufacturer repairs, they handle all the paperwork and communication on your behalf. This is much more convenient than dealing directly with manufacturers or online companies.

Our network relationship also means faster turnaround times for repairs, and your audiologist can often provide loan hearing aids while yours are being repaired. All routine maintenance and cleaning is included in our service.

Question 25

​Can I trust an at-home hearing test to be as thorough as one done in a clinic?

Accepted Answer

Our audiologists conduct the same comprehensive hearing assessment in your home as they would in a clinic setting. They bring professional-grade equipment and create a controlled testing environment. The advantage of a home visit is often better - you're more relaxed in familiar surroundings, and your audiologist can assess your specific listening challenges in your actual living environment.

They can also involve family members in discussions about your hearing needs. This is very different from online hearing tests, which lack professional oversight and proper equipment. Our home-based assessments maintain all clinical standards while offering superior convenience.
