TL;DR. Seven virtual data rooms UK fundraising teams actually evaluate in 2026: Beamprobe, iDeals, Datasite, Firmex, Onehub, Papermark, and ShareVault. They split into three tiers by deal size and pricing. This is the honest comparison — what each is built for, what it costs, and where each cuts corners.
The seven
| Tool | Tier | Starting price | UK residency | Time to first room |
|---|---|---|---|---|
| Beamprobe | Modern | £29/mo | UK only | 90s |
| Papermark | Modern | £19/mo | EU | 5min |
| Onehub | Mid | £25/user/mo | US default | 15min |
| ShareVault | Mid | £40/mo | EU optional | 1 day |
| iDeals | Enterprise | £460/mo | EU optional | 1-3 weeks |
| Datasite | Enterprise | £750/mo | Multi-region | 1-3 weeks |
| Firmex | Enterprise | £899/mo | Multi-region | 1-3 weeks |
How to read this comparison
Three things determine which VDR fits a given UK transaction:
- Deal size — £1m vs £100m changes which features actually matter
- Buyer profile — strategic acquirer vs Tier 1 bank PE arm
- Residency requirements — UK only, EU acceptable, US permitted
If your deal is under £50m and your buyer is a UK strategic or SME-friendly PE, the modern tier is almost always the right answer. If your deal is over £100m and your buyer’s counsel insists on SOC 2 Type 2, you’re in enterprise territory.

Pricing: £29/month (Pro), £79/month (Business, up to 15 staff), £249+/month (Enterprise).

Pricing reality
8-week UK fundraise cost:
| Tool | Total |
|---|---|
| Beamprobe Pro | £58 |
| Papermark Pro | £38 |
| Onehub (3 users) | £75-120 |
| ShareVault | £80+ |
| iDeals | £920+ |
| Datasite | £1,500+ |
| Firmex | £1,798+ |
For a typical 12-week M&A:
| Tool | Total |
|---|---|
| Beamprobe Pro | £87 |
| Papermark Pro | £57 |
| Onehub (3 users) | £113-180 |
| ShareVault | £120+ |
| iDeals | £1,380+ |
| Datasite | £2,250+ |
| Firmex | £2,700+ |
The modern tier saves £1,000-£2,500 per typical UK deal. The enterprise tier saves nothing because there is no equivalent option below their tier — they exist for transactions where the data room cost is rounding error.
How to choose in 5 minutes
Three questions:
1. Is your deal under £50m? Yes → modern tier. No → mid or enterprise.
2. Do you need SOC 2 Type 2 audited evidence? Yes → enterprise (iDeals, Datasite). No → modern fine.
3. Do you need UK data residency? Yes → Beamprobe. EU acceptable → Papermark/ShareVault. US acceptable → any.
Most UK SMB deals answer: under £50m, no SOC 2 hard requirement, UK residency preferred. The answer is Beamprobe.
