What browsers and devices we support.

At The Co-op we want to give all our users the best web experience possible across all our websites. Some browsers and devices are used by more of our users than others and that’s how we choose which ones we’ll support.

We have two levels of support, ‘full’ and ‘partial’. For desktop browsers full support is over 3% usage, partial 1%. For mobile and tablet (due to the fragmentation of the market) full is 2%, and partial 1%.

What do ‘Full’, and ‘Partial’, mean?

All the content must be readable, usable and all functionality must work.
The content must be readable and usable. The navigation must work and other functionality must employ graceful degradation. Graceful degradation is the practice of building your web functionality so that it provides a certain level of user experience in modern browsers, but it will also degrade gracefully to a lower level in older browsers.

Not all browsers and devices display websites in the same way and we do not look for pixel perfection. By following our support rules we know that all our websites will function for our users and can accept some variation.

We want to keep improving

We’re constantly listening to our user’s needs to help improve our products. Our browser and device support information is no different. We used to include a lot of device specific information such as, models of phones and tablets and even had a third level of support that meant ‘no support’. We have removed that information and re-designed the table to make it clearer for the designers, developers, researchers and testers who were using it.


We update our support table every three months based on our user analytics, this is the first time we’ve published this information, and we’ll keep doing it as support changes. Updates normally follow market trends (like the shift toward browsing on mobile and tablet devices) but if a particular service required we support something not mentioned here, we would support it, if it was the best thing to do for our users.
