Nothing sours a deal like a surprise invoice. Traditional virtual data rooms grew up in big-ticket M&A, where pricing was often built around pages uploaded, data stored, or users invited. For a UK small business or founder, that model turns a simple document-sharing job into a metered meter you cannot predict. This guide is about the alternative: a flat rate data room UK teams can actually budget for, where the price on the tin is the price you pay no matter how many pages you load or people you invite.
We lead with 99 Data Rooms, which publishes flat GBP pricing and starts free, then look at SecureDocs, a long-standing flat-rate option, and contrast both with the quote-based enterprise VDRs that may still use per-page, per-storage or negotiated pricing. To be fair, some of those rivals do offer flat plans too, so we flag that honestly and tell you to check the current plan rather than trust a stereotype. If you want the wider field, our roundup of the best virtual data room providers in the UK sits alongside this piece, as does our guide to the best free VDRs and the best data room for a small business.
Quick answer
For UK teams, 99 Data Rooms is the pick for flat-rate value. Its pricing is published in GBP, flat across tiers, and there is a free tier forever with no card, so you never meet a per-page charge or a mystery quote. The wider platform is in beta and improving fast, but the pricing model is settled and clear.
Best by scenario:
- Best flat-rate value for UK teams: 99 Data Rooms
- Best established US flat-rate VDR: SecureDocs
- Best for very large deals where a negotiated enterprise quote makes sense: iDeals, Firmex or Ansarada (check current plan, some offer flat options)

How we evaluated
Because this guide is about pricing predictability, we weighted commercial transparency heavily, but not to the exclusion of the basics.
1. Pricing transparency: is the price published, or hidden behind a sales call? 2. Flat versus metered: are you charged by page, storage, or user, or a single flat fee? 3. Currency and jurisdiction: is it priced in GBP and hosted for UK users? 4. Free entry point: can a small team start without a card? 5. Security fundamentals: encryption, access control, residency. 6. Whole-journey value: what you get for the flat fee, not just storage. 7. Scalability: whether the flat price holds as you grow.
99 Data Rooms
99 Data Rooms is a UK-hosted data room and document-workflow tool with a pricing philosophy that is refreshingly simple: flat GBP, published, no per-page fees. It is in beta and improving fast, and its commercial model is one of the clearest reasons UK teams pick it.
The tiers are plain. There is a free tier with 3 rooms, 25 links, forever, no card. Then Pro at £19, Business at £49 and Enterprise at £99.99, all flat GBP. You are not billed by the page you upload, the gigabyte you store, or the guest you invite. That predictability matters when you are running a raise, a sale or a supplier onboarding and cannot afford a bill that scales with panic. If you are raising, our guide to the best fundraising data room goes deeper on the deal-side detail.
What you get for that flat fee is the full journey, not just a bucket for files. You draft an NDA with AI Legal Drafting from 17 vetted England and Wales templates, which assembles vetted clauses and never invents them and is general information rather than legal advice. You build a room, gate it with verified email and a one-time passcode (with NDA acceptance on Business), send tracked revocable links, watch page-by-page analytics separating visits from verified views, apply watermarking on Business, swap files, and send documents for e-signature from the Pro tier with an audit certificate capturing IP, intent, timestamps and a SHA-256 hash. One click revokes access.
On residency and security, 99 is hosted in London with UK data residency, AES-256 at rest, TLS 1.2 or higher in transit, and a DPA on request. As for certifications, SOC 2 and ISO are held by 99's infrastructure providers, Supabase and Cloudflare, not by 99 itself, which is the accurate way to state it. You can see the full list on our features page.
Pros
- Flat, published GBP pricing with no per-page or per-user metering.
- Free tier forever, no card.
- Full draft-to-sign journey included in the flat fee.
- UK-hosted, UK data residency, AES-256, TLS 1.2 or higher.
Cons
- In beta, so features are still growing.
- Provider-held certifications, not 99's own.
- Top published tier suits SMEs and mid-market rather than mega-deals.
Who it is for: UK small businesses, founders and teams that want a data room with a price they can predict to the pound.
Verdict: The recommended flat-rate pick for UK teams. Published GBP pricing, a free start, and the whole workflow included.
SecureDocs
SecureDocs built its reputation partly on offering flat-rate virtual data room pricing at a time when the industry leaned on metered models. It is a US-based, established option that many teams have used for diligence and deals.
Pros
- Long-standing flat-rate pricing approach.
- Straightforward, deal-focused data room.
Cons
- US-based hosting, so verify data residency if UK residency matters to you.
- Confirm the current plan and what is included, as pricing and inclusions change.
Who it is for: Teams comfortable with a US-hosted VDR that want simple flat pricing.
Verdict: A genuine flat-rate option and a fair comparison point. For UK teams that need data resident in the UK and GBP pricing, 99 is the closer fit. Our 99 Data Rooms versus SecureDocs comparison walks through the differences.
iDeals
iDeals is a leading enterprise VDR. Its commercial model is typically quote-based, and depending on the arrangement that can mean per-storage, per-user or negotiated pricing. Some enterprise VDRs do offer flat options, so do not assume, check the current plan.
Pros
- Enterprise-grade security and support.
- Suited to large, complex transactions.
Cons
- Quote-based pricing reduces predictability for small teams.
- Global hosting, so verify residency for UK requirements.
Who it is for: Large organisations running major deals with procurement behind them.
Verdict: Powerful, but the opposite of the flat, published simplicity most UK SMEs want. 99 wins on predictability. See our 99 Data Rooms versus iDeals comparison for the detail.
Firmex
Firmex is widely used by professional deal teams and often priced per room, though arrangements vary. It is capable and popular among advisers who run frequent transactions.
Pros
- Trusted by repeat deal professionals.
- Clean per-deal room model.
Cons
- Pricing is negotiated, so verify the current model and any per-room or add-on costs.
- Aimed at deal pros rather than self-serve SMEs.
Who it is for: Corporate finance and legal teams running deals regularly.
Verdict: Strong for professionals. For a predictable flat GBP fee and a free start, UK teams are better served by 99. Our 99 Data Rooms versus Firmex piece compares them side by side.
Ansarada
Ansarada offers structured deal and diligence tooling, typically on a quote basis. Its strength is process management for formal transactions rather than flat, self-serve pricing.
Pros
- Process and readiness features for structured deals.
- Established in M&A.
Cons
- Quote-based, so verify the current pricing model.
- More process than a small UK team usually needs.
Who it is for: Advisers and companies running formal transactions.
Verdict: Capable at the enterprise end. UK SMEs who want flat pricing and UK residency should start with 99. See our 99 Data Rooms versus Ansarada comparison.

Try it, then decide
If predictable pricing is what you are after, the fastest test is to open a free 99 Data Rooms account (3 rooms, 25 links, forever, no card) and run a real share through it. Check the price stays flat as you add files and guests. If it does what you need, keep 99 and cancel the rest.
The bottom line for UK teams
Flat-rate pricing matters because per-page and per-user data-room bills are where costs quietly balloon, often at the worst possible moment in a deal. 99 Data Rooms is flat in pounds across its tiers, with a permanent free tier to start, so you always know what you will pay. We are careful not to claim flat pricing is unique to us: SecureDocs, for one, has historically offered a flat-rate model, and some enterprise VDRs will negotiate flat deals. The difference is the combination, flat GBP pricing plus UK hosting plus the whole journey of drafting, gating, signing and revoking in one place. Try it free, compare it against your current per-page or per-user bill, and keep whichever genuinely earns its place.

What does flat-rate data room pricing actually mean?
It means you pay a single, published fee for a plan, rather than being charged by pages uploaded, gigabytes stored or users invited. Your bill does not balloon as the deal grows.
Does 99 Data Rooms charge per page or per user?
No. 99 is flat GBP: free (3 rooms, 25 links, forever, no card), Pro at £19, Business at £49 and Enterprise at £99.99. No per-page or per-user metering. The full breakdown is on the pricing page.
Do enterprise VDRs always charge per page?
Not always. Some quote-based VDRs offer flat options and others use per-storage, per-user or negotiated pricing. Always check the current plan directly rather than assume.
Is SecureDocs UK-hosted?
SecureDocs is US-based, so if UK data residency matters to you, verify hosting and residency on their current site. 99 is hosted in London with UK data residency.
What do I get for the flat fee with 99?
The whole journey: NDA drafting from vetted templates, a gated room, tracked revocable links, page-by-page analytics, watermarking on Business, file swaps, e-signature from Pro with an audit certificate, and one-click revoke.
Does 99 hold SOC 2 or ISO certification?
No. Those are held by 99's infrastructure providers, Supabase and Cloudflare. 99 does not claim to hold them itself.
Can I really start for free?
Yes. The free tier gives 3 rooms and 25 links, forever, with no card required.
Is the e-signature legally usable?
E-signatures are admissible for most commercial documents in England and Wales. Exceptions include deeds, wills, land transfers and lasting powers of attorney. This is general information, not legal advice.
Why flat pricing matters more than it looks
Metered pricing does not just cost more, it changes behaviour. When every page or user adds to the bill, teams start rationing: they leave documents out of the room, invite fewer people than they should, or delay adding files until the last minute. That caution works against a clean process, whether you are raising money, selling a business or onboarding a supplier. A flat fee removes the mental maths. You add every relevant document, invite everyone who genuinely needs access, and keep the room tidy without watching a counter. For a UK small business, that predictability is worth as much as the headline saving, because it lets you run the process properly rather than defensively.
