Raising from US VCs as a UK company — what changes in the documents?
By SuLe · Updated 11 July 2026
Raising from US VCs as a UK company usually means NVCA-influenced documents (or BVCA docs with US riders), Delaware-style protective provisions and possibly a US-law side letter — and sometimes, though less often than before, a Delaware flip. The commercial deal looks familiar; the drafting conventions and some protections follow US norms. The key warning: SEIS/EIS and EMI do not travel into a US topco.
Key facts
- US rounds often run on NVCA-influenced documents, or UK BVCA documents with US riders bolted on.
- Expect Delaware-style protective provisions and sometimes a separate US-law side letter.
- Some US funds require a Delaware topco (the "flip") — but many now invest directly into UK companies.
- SEIS/EIS relief and EMI options do not carry into a US topco.
- US investors commonly ask for QSBS/PFIC tax analysis and US-style representations — route these to their advisers.
Which documents change when the lead is American?
The template, mostly. A US-led round may run on documents influenced by the NVCA (the US National Venture Capital Association) model forms, or on familiar UK BVCA-style documents with US riders added on top. [More: What are the BVCA model documents?]
The commercial substance — investment amount, valuation, board rights, the money into the company — mirrors a UK round. What shifts is drafting style: different definitions, longer representations, and protections framed the US way.
Do not assume a US paper set is heavier just because it is unfamiliar. Read it against what a UK round would give the investor, and negotiate on substance rather than being spooked by format.
What US-style terms should I expect to negotiate?
Three recurring features: Delaware-style protective provisions, a possible US-law side letter, and expanded US-style representations and information rights.
Protective provisions are investor consent rights over defined actions — issuing shares, taking on debt, changing the business. UK rounds have their equivalent in reserved matters, so the concept is not new, but the US drafting can be broader; check the list carefully.

A side letter may grant one fund extra rights outside the main agreement. And US investors frequently want QSBS or PFIC tax analysis and detailed reps — US tax concepts that depend on their position, not yours, so pass them to their advisers rather than reshaping your company.
Will a US VC force a Delaware flip?
Sometimes, but far less automatically than founders fear. A number of US funds now invest directly into a UK company; only some still require a Delaware parent as a condition of investing.
If a flip is required, treat it as a serious structural decision, not a formality. A Delaware flip is a share-for-share exchange that puts a US company on top of yours — and it can withdraw SEIS/EIS relief if it happens within three years of a relief-bearing issue.

Ask for the requirement in writing, check whether direct UK investment would satisfy the fund, and map your existing investors' relief windows before you agree to anything.
What happens to my SEIS/EIS and EMI in a US round?
If you stay a UK company, taking US money changes nothing about SEIS/EIS or EMI — those reliefs run on the UK company as before. The risk appears only if you restructure above it.
SEIS/EIS relief and EMI options do not travel into a US topco. Flip to Delaware and you can withdraw SEIS/EIS relief within the three-year window, and your EMI options need careful rollover analysis because the scheme is UK-specific. [More: Can non-UK investors claim SEIS or EIS relief?]
So the cleanest way to protect your early investors and your option holders is to resist an unnecessary flip. Keep the UK company at the top unless a concrete requirement genuinely forces the change.
| Feature | UK-led round | US-led round (UK company) |
|---|---|---|
| Base documents | BVCA-style | NVCA-influenced, or BVCA + US riders |
| Consent rights | Reserved matters | Delaware-style protective provisions |
| Side letters | Sometimes | Common for the lead fund |
| Structure change | None | Delaware flip required by some funds only |
| SEIS/EIS & EMI | Preserved | Preserved unless you flip to a US topco |
Worked example
Marcus and Yara run a UK AI-infrastructure startup and take a $3m round led by a US fund, keeping the UK company at the top. The fund uses NVCA-influenced documents with US-style protective provisions and asks for a side letter granting it enhanced information rights.
Their lawyers map the protective provisions onto the reserved matters the founders already understand and trim two that overreach. Because the company builds AI, they also confirm whether the National Security and Investment Act 2021 applies to the deal. The fund does not require a Delaware flip, so the founders' SEIS and EIS investors keep their relief and the EMI pool stays intact — the outcome they were most determined to protect.
Where founders go wrong
Agreeing to a Delaware flip too readily
— many US funds invest directly into UK companies; get the requirement in writing and test whether it is really needed.Signing broad protective provisions unread
— US drafting can be wider than UK reserved matters; negotiate the list, not just the headline.Forgetting SEIS/EIS and EMI don't travel
— a flip within the three-year window can withdraw relief and forces EMI rollover analysis.Trying to answer QSBS/PFIC yourself
— these are the investor's US tax questions; route them to their advisers.
Related questions
Do US VCs use different investment documents?
Usually. Expect NVCA-influenced US documents, or BVCA-style UK docs with US riders, plus Delaware-style protective provisions and sometimes a US-law side letter. The commercial substance is similar to a UK round, but the drafting style, definitions and some protections follow US market practice.
Will a US VC make me flip to Delaware?
Some do, many no longer do. A number of US funds now invest directly into UK companies. If a fund requires a Delaware topco, get the requirement in writing and check your existing investors' SEIS/EIS three-year windows first, because a flip can withdraw their relief. [More: What is a Delaware flip and does my UK startup need one?]
What happens to SEIS/EIS and EMI when I raise from a US fund?
If you stay a UK company, SEIS/EIS and EMI are unaffected by taking US money. But they do not travel into a US topco, so a Delaware flip can withdraw SEIS/EIS relief within the three-year window and forces careful rollover analysis for EMI options.
What extra tax questions will US investors raise?
US investors commonly ask for QSBS or PFIC analysis and US-style representations and information rights. These turn on the investor's US tax position, not your company's, so route them to the investor's own advisers rather than restructuring reflexively.
