Companies House sincerely regrets the delay of announcing a test platform for the schemas due to come in effect on 18th November. I can confirm the testing service is now available.

The platform only currently offers XML schema validation.

**Testing details**

You can use your live presenter credentials - but show Package Reference as 0012 and Test Flag as 1.

Endpoint: [https://xmlgw-sandpit-staging.companieshouse.gov.uk/v1-0/xmlgw/Gateway](https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fxmlgw-sandpit-staging.companieshouse.gov.uk%2Fv1-0%2Fxmlgw%2FGateway&data=05%7C01%7C%7Cc3eaeac1f0f849b3350108dbecbe3e25%7Ce6acfe5e7f2a455a9d85ecf93371f601%7C0%7C0%7C638364074069408765%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=WxvsfX5YkgupcKBhNyi1sbKxgoazb1LSBZ57E8HYps0%3D&reserved=0)

If you receive an XML schema validation error, then the schema is failing due to a syntax error or incorrect basetype compatibility - and should be considered a failed test.

If you receive any other error response, such as an authorisation failure, then that means the schema has passed the schema validation stage, and should be considered a successful test.

For reference, the following is a link to the test service schema page.
