WR1.HK / PRACTICAL GUIDE
Hong Kong WR1 for property owners in Mainland China
This guide concerns Hong Kong properties. Prepare the relevant information first; suitable registered electrical teams must handle the site work, inspection and testing.
Sources checked: 25 October 2026Provide the Hong Kong project details
Enter the district, full project address, contact person, +86 or +852 phone and requirements. Record owner and contact separately. Unknown technical values can be checked later.
Gather existing records
Prepare any previous WR1, scope, drawings or electricity bill for assessment. Do not submit identity-document copies, passwords or unrelated personal information through the initial enquiry form.
Arrange local access
Agree who can provide access and coordinate with building management. Check any authority or evidence required for utility applications separately. A website enquiry does not itself grant that authority.
Complete the Hong Kong site checks
Photos and an online form help preparation; they do not replace necessary on-site work. The responsible team checks the scope, test results and any remedial work before processing WR1.
Check the handover
Verify owner, address, scope and responsible-party details. The appropriate parties sign and endorse the certificate. Keep the WR1 and provide a copy for a utility application when required.
