WooCommerce is proposing to raise its minimum PHP requirement to version 8.1 from WooCommerce 11.5, currently targeted for January 2027.
The change is not final. WooCommerce is asking store owners, agencies, hosting providers and extension developers for feedback before confirming the release target and minimum version. If adopted, future WooCommerce releases would stop supporting PHP 7.4 and PHP 8.0.
WooCommerce says around 7% of tracked stores are still running PHP 7.4 and a further 2% use PHP 8.0. Its usage data is opt-in, so the figures are a representative sample rather than a complete count of every WooCommerce store.
For businesses still on those older versions, the important point is that WooCommerce would not automatically change the server’s PHP version. WordPress would normally prevent WooCommerce 11.5 from being offered until the hosting environment met the new requirement. The existing store would remain on the latest compatible WooCommerce branch instead.
UK small businesses should not treat that as a reason to wait until January. A PHP upgrade can expose compatibility problems in older themes, payment gateways, shipping tools, custom code and other extensions. WooCommerce itself says testing on a staging site remains important.
There is also an important distinction between the proposed minimum and the version businesses should ideally be running. PHP 8.1 has already reached end of life according to the PHP project’s supported-version schedule. WooCommerce’s current server recommendations call for PHP 8.3 or greater.
That means a shop moving away from PHP 7.4 or 8.0 should not automatically aim only for 8.1. The safer approach is to check what the host supports, confirm compatibility across the store’s extensions and theme, take a full backup and test a currently supported PHP branch before changing the live site.
Businesses without an established update process can use a structured website maintenance and support routine to test server changes alongside WordPress, WooCommerce and plugin updates. Where a change causes checkout failures or a critical error, Core Web UK’s emergency website fixes guide explains the types of failures that can follow incompatible updates.
WooCommerce published the proposal on 8 September 2026 and says it will review feedback and usage data before confirming the final requirement. For store owners, the useful action now is to find out which PHP version their site is actually running and whether any critical extensions still depend on an older branch.
