    Following the latest Government advice, we’ve had to make some changes to our services.

    We can still collect your old appliance and take it away for recycling. You’ll just need to make sure it’s by the entrance to your property ready for us to collect, as we won’t be able to remove it from any other room in your home.

    We’ll happily take away your old TV for you and recycle it. All we ask is that it’s unplugged and ready to go. The fee for this service relates to the cost of taking your old TV away on our van rather than the recycling service.

A more cinematic experience

Experience cinema-quality viewing thanks to the advanced HCX processor. This clever bit of tech continuously adjusts the contrast and balance on-screen to enhance your favourite blockbuster titles. The result is a picture and colour quality much closer to that which the director intended.

Spectacular colour and contrast brings content to life

HDR technology adds amazingly lifelike colour and depth to your favourite shows and movies for a truly spectacular cinematic experience. But it’s easy to feel overwhelmed by all the different kinds out there, especially since broadcasters and streaming platforms don’t always use the same one. Luckily, this model supports a huge range of HDR formats, including HDR10+ and Dolby Vision, letting you enjoy an enormous amount of content in the best possible quality.

Panasonic 58gx800b

Received this TV last week and overall up till now I'm extremely impressed with it. It has replaced an LG (47la660v) which has been a great servant but so far everything has been good. Unpacking is OK but should be done with two people and you will need two to fit it to the stand. It looks terrific when assembled, very sleek and stylish. On switching on setup is very easy, it finds the network and freeview channels very quickly and you are up and running after a few minutes. Picture quality out of the box is a bit dull but after adjusting a few settings I've got it the way I want and it is excellent. Freeview quality is top notch, blu rays look stunning also. The only 4k footage I've had through it was streamed from You Tube but it looks amazing. I've got it rigged up to a home theatre system for sound but even without that the sound from the TV itself is better than I thought it would be and easily fills a living room space and is good quality. Moving through Apps is extremely quick and easy, some people have said it looks a bit dated compared to LG and Samsung interfaces but it is functional and easy to understand and I'm happy with it and it does the job very well. I'm really happy with this TV so far. For the price I think you are getting some great features and unless you have a large budget for Oled then thisshould tick just about all the boxes for a mid range TV. It's won a few awards for its performance and I can see why. Just be prepared to spend some time with picture settings to get the most out of it as lighting etc in every lounge may be slightly different. There have been some reviews mentioning restrictions on viewing angles. I have one sofa at an angle and I haven't noticed any issue with it to date. I'd thoroughly recommend this product and added to that the service from AO was excellent.

Panasonic 58" TV

Great service. TV looks great, easy to set up and use.

christmas present success

So me and my siblings got this tv for my dad he has always had Panasonic tv’s and this one didn’t disappoint. Sound quality is excellent, picture is amazing and connecting it to all his other devices was a dream. Good quality good price and vivid colours makes one happy dad.

Couldn't have been better.

Brilliant clarity and great sound quality, much better than we had before. Easy to put together and works well with our decor.

Love it!

Perfect size tv for my living room. Got all my apps as nextflix youtube and amazon prime with just a push of a button. Picture quality is amazing Only negative is the placement of the power button but will eventually get use to :) Amazing product worth the money

Very good TV

I bought this TV based on the reviews on this site. I’m not dissatisfy at all. The picture and sound is very good for a TV of this price. Very happy with the purchase.
