The HRB Gateway 2 compliance bundle that gets accepted by your principal contractor first time.

SubBundle takes your job inputs and produces a single PDF mapped to CAS V5 Building Safety, CDM 2015 RAMS to HSE L153 standard, and the BSR's Application Information Schedule — built for UK construction subcontractors (5–50 employees) on Higher-Risk Building projects under the Building Safety Act 2022. Director-reviewed by Cai Morgan before delivery while we're at Stage 1.

Tier-1 contractors are tightening documentation. Most subs are bodging it.

The Building Safety Act 2022 turned subcontractor evidence into a stop/go gating point at BSR Gateway 2. Three patterns trade press has been documenting through 2025–2026:

RAMS that get rejected

Risk assessments listing hazards without specific control measures. Method statements too vague to function as working documents. Tier-1s reject; payments slow.

→ HSE L153 standard

Duplicate evidence packs

The same evidence reformatted four times for four different tier-1 portals. CAS V5 was meant to fix this — only works if your evidence is CAS-aligned to start with.

→ Build UK · 9 named tier-1s

No fit-for-purpose tool

Enterprise platforms (Zutec, Procore) cost £500+/month, target tier-1s. Sole-trader RAMS tools at £30/month don't map to HRB Golden Thread requirements. The 5–50 employee subcontractor sits in the unserved middle.

Send your job inputs. Receive a principal-contractor-acceptable bundle.

At Stage 1 — where we are now — every bundle is produced and then reviewed by Cai Morgan, Director, before it's sent back to you. The first generation of bundles need a human eye on every output to make sure the standard is right before any of it scales to self-serve.

1

Tell us about the job

One short intake form covers project details, your trade scope, what your principal contractor is asking for, and which scheme they assess against — CAS, CHAS, SafeContractor, SMAS, or Constructionline.

2

Drop your inputs into a shared folder

Drawings, photos, certificates, training records, supplier paperwork. Whatever you have. We work with what's there and flag what's missing before drafting starts.

3

Receive a CAS V5 / CDM 2015-aligned bundle

One PDF: project particulars, CAS V5 Building Safety answers, task-specific RAMS to HSE L153 standard, AIS-mapped fields, evidence index, customer sign-off page. Reviewed by Cai Morgan before it reaches you.

4

You review, sign off, submit

You're the last set of eyes. SubBundle drafts and structures — you're responsible for accuracy and final approval. That's the legal posture and we're explicit about it on every output.

£149 per bundle. No subscription.

One price for one bundle, paid after you've reviewed it. Stage 1 is deliberately small — five paid pilots before anything resembling a subscription product exists.

Once Stage 1 validates, the product moves to a subscription model with self-serve generation. Provisional tiers around £79 / £149 / £299 per month per firm — but that's a Stage 3 conversation, not a Stage 1 commitment.

Pre-product. Pre-scale. Deliberately small.

SubBundle is a Stage 1 concierge product from Morgan and Co. Enterprise Limited, a UK Limited company directed by Cai Morgan. How bundles are produced, plainly: SubBundle uses AI tooling to draft and structure your documentation from your inputs. Cai then reviews each draft before it's delivered to you. The drafting is automated; the human sign-off is the gate. There are no automated submissions, no scaled team, no enterprise SLA — by design.

What that means for you: the first five pilots get a level of human-review attention that won't be sustainable later when this scales to self-serve. If you take a pilot now, you're getting AI-drafted compliance documentation with a human reviewer in the loop, at the price point a future self-serve tool will eventually sit at — and you're informing what the automated version becomes.

SubBundle is a non-regulated software vendor under the Building Safety Act 2022. It does not make anyone "competent" under Section 156. It drafts and structures documentation; you, the customer, are the last set of eyes — responsible for reviewing, verifying, and approving the final content before submitting to your Principal Contractor or any regulator.

Everything we usually get asked.

What size of UK construction subcontractor is SubBundle for?

5–50 employees, working on or aiming for Higher-Risk Building (HRB) projects. If you are a sole trader doing domestic work, the documentation overhead probably isn't worth it for you yet — there are good £30/month RAMS tools that fit your scale better.

Which trades does the SubBundle Stage 1 pilot cover?

Fire-stopping (passive fire protection) is the strongest fit and the trade we have the most evidence library for. Façade and cladding remediation, M&E specialist installation, drylining, and structural waterproofing are also in scope. Other trades on request — we'll tell you up front if the evidence library is thin.

How do I produce CAS V5 Building Safety section answers?

CAS V5 Building Safety is the section of the Common Assessment Standard introduced 1 October 2025 that covers Higher-Risk Building competence. Producing the answers requires task-specific evidence (RAMS to HSE L153 standard, training records, supplier certificates, method statements) mapped to specific CAS V5 question codes (BS-1.1, BS-2.3, BS-3.1, etc.). SubBundle drafts the answers from your inputs and structures them into the CAS-aligned format your principal contractor's scheme will accept.

What is the AIS (Application Information Schedule) for HRB projects?

The Application Information Schedule (AIS) is the structured-data format the Building Safety Regulator (BSR) uses to receive Gateway 2 applications for Higher-Risk Buildings under the Building Safety Act 2022. AIS-mapped evidence means your subcontractor documentation is structured to feed cleanly into the principal contractor's AIS submission — fields aligned, references consistent, evidence index matched to AIS schema. SubBundle produces AIS-mapped evidence as standard.

How does a UK subcontractor pass BSR Gateway 2 on a HRB project?

Subcontractors don't submit to BSR directly — the principal contractor submits the Gateway 2 application. The subcontractor provides evidence the principal contractor incorporates into that submission. To pass, your evidence must be: CAS V5-aligned (or CHAS / SMAS / SafeContractor / Constructionline equivalent depending on the scheme); RAMS to HSE L153 standard with specific control measures (not generic templates); structured to map into AIS fields. The 67% Q1 2026 Gateway 2 approval rate reflects that getting subcontractor evidence right is the hard part.

What if my Principal Contractor uses Procore, Zutec or Asite?

SubBundle's bundle is designed to feed into those platforms, not replace them. The principal contractor receives evidence from you that fits the format their tool expects. We don't replace tier-1 systems — we make sure your end of the chain holds up.

What happens if a SubBundle compliance bundle gets rejected?

We rework it once at no extra charge. If it gets rejected again for a reason within our scope, we refund the full £149 and issue a written record of what was missing. Either way, we want to know — every rejection is the strongest signal we get about what to improve.

How does SubBundle handle UK GDPR and customer data?

Customer-supplied inputs are processed under a written Data Processing Agreement (Article 28) drafted alongside the customer T&Cs at Stage 2. Data residency is UK. Personnel data uploaded into RAMS templates is processed only for the bundle output and retained for 12 months after delivery unless you ask us to delete sooner. Nothing is shared with third parties without your explicit written consent.

Why is SubBundle £149 per bundle?

It's the Stage 1 concierge pilot price — anchored at what a future automated tier will eventually sit at. The cost reflects the human-review layer in the loop right now: Cai Morgan reviews every bundle before delivery. Once Stage 3 self-serve is live, the price will likely be a monthly subscription with multiple bundles included; £149-per-bundle is a Stage 1 number specifically.
