Hello,
I have found a reproducible defect in the September 2026 Basic Company Data Product.
Affected archive
BasicCompanyDataAsOneFile-2026-09-01.zip
Affected CSV
BasicCompanyDataAsOneFile-2026-09-01.csv
The CSV header contains the expected 55 fields, but one non-blank data record parses to 56 fields.
Affected company
- Company name:
SENTINALL LIMITED - Company number:
08652773 - Data row: approximately
4,502,219
The problem appears around the SIC fields. The row contains:
SICCode.SicText_1 = 56290 - Other food services
SICCode.SicText_2 = 62012 - Business and domestic software development
SICCode.SicText_3 = 62020 - Information technology consultancy activities
SICCode.SicText_4 = 62090 - Other information technology service activities
It then contains an additional value:
63110 - Data processing, hosting and related activities
where LimitedPartnerships.NumGenPartners should begin.
This shifts every subsequent value one field to the right, and the record has a 56th value beyond the 55-column schema.
Could Companies House please confirm whether the September Basic Company Data Product can be corrected/reissued?
Thanks.
