Digging around on the wayback machine I found this snippet from the webpage about the Price for Life offer:
Lifetime Price Guarantee
We like to go one better than no mid contract price hikes. As long as you stay with Zen, we'll never increase your price - on all our 12, 18 or 24 month packages.
Also found the email they sent back in May with a (slow) link to their website (https://www.zen.co.uk/contract-price-promise)
The email states:
Upcoming changes to Price for Life
Over the last few years, we’ve been proud to provide all our customers with a Price for Life (also known as a Lifetime Price Guarantee) on our broadband packages. This is our pledge that for as long as you stay on the same package the price of your Zen broadband service will never increase.
As an existing customer, our promise remains in place for your current broadband package.
Since we launched Price for Life, the world has changed in ways we couldn't have predicted. Inflation is at its highest in decades and our costs continue to increase. To ensure that we can continue to invest in our people, the planet and to deliver a consistently high level of service to our customers, our Price for Life offer will no longer be available for new contracts.
