Company affidavit only or Full corporate document set — choosing the right route for energy and infrastructure project document certification
This page compares the two certification routes used for energy and infrastructure project document certification: when each applies, how many layers are involved, which authorities take part, what the translation must look like, and the mistakes that most often send a file back.
| Aspect | Company affidavit only | Full corporate document set |
|---|---|---|
| Scope | A single affidavit | Affidavit, memorandum of association, shareholder list, and board resolution |
| When it applies | The destination only needs proof of corporate existence | Setting up a subsidiary, opening a bank account, or bidding for work |
| Names and titles | Must match the registered filing | Must match across every document in the same set |
| Document age | Usually must be freshly issued within the destination's window | Every document should be issued in the same round |
| Risk | A later document request means a second certification round | Higher cost in one round, but fewer repeat filings |
| Common mistake | Using an English company name that differs from the registered one | A resolution signed by someone without authority under the affidavit |
How to choose
- If the destination is a bank or a registry, prepare the full set in the first round.
- Always verify signing authority in the affidavit before drafting the board resolution.
Documents to prepare
- Freshly issued company affidavit and certificate of registration
- Memorandum and articles of association, or the current shareholder list
- Board resolution or power of attorney signed by the authorised director
- ID or passport copies of the authorised signatories
- Registered English company name and job titles exactly as filed
- Counterparty or destination authority requirements for the certified set
Support continues after delivery
Document work rarely ends with one submission: the receiving authority may request more, or you may need to file again next year. We keep a digital copy set and a record of the certification route used for every job, so the next round starts from the right point, and you can consult us when the destination changes its requirements. Handled by a team with more than 15 years of experience.
- The certification route of each job is recorded for the next round.
- Guidance when the destination requests additional documents later.
- New document sets checked for consistency with what you already filed.
