Free decision tools for UK construction operators. CADSnap + TradeSnap. Retention release, payment notices, adjudication maths, bond logistics, CIS deductions — calculated against current UK construction law.
Built around the construction operator's actual day. No subscription, no paywall, no funnel theatre. Free is the funnel; the tools themselves are real. Operator-list only for the deeper sector intel digest.
Each one scoped to one operating question. Free to run. Open to anyone in the UK construction sector.
CADSnap is for the QS / main-contractor side of the payment chain — retention release, payment notices, adjudication maths, bond logistics, CAD conversion. TradeSnap is for the trade-operator side — job costing, invoicing rhythm, CIS deduction maths, retention chase. Both run free in the browser. No login. No paywall.
Every snap inside CADSnap and TradeSnap maps to one of six recurring operating questions. The maths is hard-coded against current UK statute and standard contract forms.
Half-retention on practical completion. Full retention on end-of-defects-liability. Retention reform watch. JCT vs NEC vs subcontract forms. Insolvent main-contractor routes (employer, bond, parent guarantee).
Pay-less notice generator. Payment notice (under Construction Act s.110A). Final payment notice. Default payment notice. LDEDC Act 2009 amendment compliance. Timing windows and trigger events.
Sum-in-dispute calculations. Interest under the Late Payment Act + JCT/NEC clauses. Adjudicator fee splits. Costs-recovery routes. Statutory adjudication vs contractual. Smith v Mills doctrine summary.
On-demand vs conditional. Performance vs payment. Parent-company guarantee vs surety. ABI standard vs ICC standard. Trigger events, claim-by date, expiry handling, replacement bond logistics.
20% / 30% / gross-payment status calculation. Subcontractor verification flows. Monthly return prep (CIS300). Penalty maths. Gross-payment-status thresholds. New CIS reform tracking.
DWG / DXF / PDF utility set. Layer / hatch handling. Bills-of-quantity extraction. Scale verification. Drawing-register tracking. Plus working-out for as-built drawings vs construction issue.
Builders Trust is the calculator drawer for the operator chasing the money down the chain. Free tools for the questions the construction sector knows the answer to but never quite has time to do the maths on.
The brand is owned by Craig Attoh's best friend — a UK industrial / construction-services operator who built the calculator set in the first place because the consultancy version cost six months of fees for what was, in the end, a working spreadsheet. The deal: keep the tools free, route the deeper builds through the wider ATTOH Digital agency tier inside AMAYA Holdings.
The construction sector has been undersold by SaaS and oversold by consultancies for twenty years. The deals get signed against PDFs and the disputes get settled in adjudication. The maths is the maths — JCT, NEC, the Construction Act 1996, the LDEDC Act 2009, the Late Payment Act, CIS regulations, retention reform watch — and most operators do not have time to keep all of it in their head.
Builders Trust does the maths. The tools are even-handed: CADSnap surfaces what the operator on either side of the payment chain needs to know. JCT and NEC cut both ways. We just give the maths.
The brand is UK-only, construction-only, and R&D-eligible — the engineering work that builds the calculator set feeds into the wider AMAYA Holdings R&D claim. There's a Chinese contact and a UK council link inside the partnership network for operators working off-site or modular. The infrastructure underneath is the ATTOH.tech engineering stack — same plumbing that runs the rest of the group's tooling.
If you are looking for the maths on a retention chase, an adjudication, or a payment notice — this is the right drawer.
The snap drawer stays free. The sector intelligence digest is email-gated. The deeper custom build is the paid route — and that runs through ATTOH Digital inside AMAYA Holdings.

— Builders Trust
Builders Trust is owned by Craig Attoh's best friend — a UK industrial / construction-services operator who built the calculator set in the first place because the day-to-day questions kept costing six months of consultancy fees to settle. The deal: keep the tools free, route the deeper builds through ATTOH Digital inside AMAYA Holdings.
UK-only. R&D-eligible. There is a UK council link and a Chinese contact inside the partnership network for operators working off-site, modular, or import-heavy supply chains.
Builders Trust does not publish customer names. Below are anonymised reflections from operators who have run the snaps. Names available on request, post-mandate.
Ran CADSnap on a retention chase that had been open fourteen months. Came out with the exact statutory route and the maths to back it. Money landed three weeks later. The QS owed me a pint.
The adjudication-maths snap saved us about £40k in retainer fees. We didn't need the QS firm for the first pass — we needed the maths to know whether to instruct them at all. Builders Trust gave us that for free.
We use TradeSnap for the CIS deduction maths every month. The verification flow is exactly what HMRC wants. Saved us moving to a paid sub-contractor management tool for an extra £180 a month.
The bond-logistics snap on a parent-company guarantee question would have cost us two weeks with the solicitor. Builders Trust gave the framework in five minutes. We instructed the solicitor on the right question.
Came in through CADSnap, ended up on the operator-list, then engaged ATTOH Digital for the custom site build. The handoff between the free side and the paid agency tier is invisible — same standard, same care.
Used the payment-notice generator on a pay-less notice that was on the line between Construction Act compliant and not. The snap surfaced the timing window and the wording. We won the dispute without going to adjudication.

Every snap is calibrated against current UK construction statute, standard contract forms, and recent case law. Updated quarterly. Last calibration window: MMXXVI Q2.
