 Trustindex verifies that the original source of the review is Google. Cannot praise these guys enough. Hugely helpful during a recent amplifier repair for my C-Class. Explained the options, gave excellent advice and facilitated successful resolution. I would not hesitate to go there again, even though it is a 120 round trip for me. This really was good old-fashioned service and you are treated like a customer, not a punter.

 Trustindex verifies that the original source of the review is Google. I recently enquired with B & B Audio Concepts about upgrading the media unit in my BMW, and I couldn’t be happier with the service.

The parts were ordered and fitted within just a few days. My BMW is a 2009 model and, believe me, it was definitely in need of an update! The new unit has brought the car right into 2026. It’s touchscreen, compatible with Apple CarPlay and Android Auto, and is an absolute joy to use.

I was listening to my Spotify tunes on the drive home! 🎶

The fitting itself was quick and professionally done. Fantastic service from start to finish.

5-star service from me! 👍⭐⭐⭐⭐⭐

 Trustindex verifies that the original source of the review is Google. Absolutely Outstanding Service & Results!

I honestly can’t recommend Waz and his team highly enough. The service has been nothing short of exceptional, and the results have genuinely exceeded my expectations.

From the very first consultation right through to the finished installation, the professionalism, knowledge, attention to detail and workmanship have been second to none. What really stood out was the honest advice from the very beginning — no pushy sales, just genuine expertise and recommendations based on exactly what I needed.

The end result is even better than I could have imagined. Waz and his team clearly take huge pride in what they do, and that shows in every aspect of the work.

If you’re looking for a team you can trust completely with your audio and security needs, look no further. Waz and his team are the people to speak to.

A genuine 5-star experience from start to finish. I’m absolutely delighted with the results and wouldn’t hesitate for a second to recommend them to anyone. Outstanding work! 👏🔥

 Trustindex verifies that the original source of the review is Google. Can’t thank Was & the team enough for an amazing job.

I had an idea of what I wanted for my classic Mercedes SL and spent some time with Was discussing my options and listening to his advice and recommendations.

I’m so glad I took his advice, his no pressure approach and honesty is great, the end result was me wanting to spend more time in my car yesterday when I collected it listening to my music, driving with a big smile on my face.

I would highly recommend you spend time with Was, go with his advice and recommendations and end up with something better than you expected.

Thanks guys 10/10

Visited Waz and the guys to discuss getting an alpine head unit fitted to my Transporter.
From the moment i started asking questions I knew I had come to the right place!
Very knowledgeable guys. Talked me through all options with no sales pressure whatsoever.
Even when I mixed up fitting date they were super helpful and fitted me in.
Over the moon with both the product fitted and customer service.
Any audio requirements....go see B&B.
Thanks again guys.

 Trustindex verifies that the original source of the review is Google. I had a problem with my a45s ( No Bass ) WAZ found the problem within minutes and advised me to look for the part myself as he would be a lot more money for a simple fix . What an amazing and honest guy.   Highly recommend👍🏻 THANKS WAZ

 Trustindex verifies that the original source of the review is Google. Couldn't be happier with the work B&B Audio Concepts did on my Ferrari 360 Spider. Waz fitted a retro-style Pioneer head unit, DAB aerial, and a new amp/subwoofer setup — genuinely magnificent result. I went in expecting to replace the speakers too, but Waz took one look and told me my Diamond speakers were too good to swap out — honest advice that saved me money I was fully prepared to spend, and the sound is fantastic as a result.
The quote was stuck to exactly, no surprises. What really stood out was the care taken with the car itself — everything installed to a standard that means it could be returned to factory spec if I ever needed to, which says a lot about the attention to detail and respect for the car. No wonder B&B's reputation is what it is. Totally justified, and highly recommended for anyone wanting audio work done properly on a car that matters to them. Thank you Waz 👌👍

 Trustindex verifies that the original source of the review is Google. I came to Waz at B&B for an audio system upgrade. Initially, I was just looking for a Harman Kardon-style upgrade to replace my stock system, but Waz assured me that what he offered would be even better, and he was absolutely right.

The difference is incredible. Bass, mids, and highs all sound amazing, especially compared to the standard setup. The OEM style fitment is flawless, and the customer service was outstanding throughout. I couldn't be happier and would highly recommend B&B to anyone looking to upgrade their audio system.
