// For scaffolding contractors

Every scaffold erected, inspected and on record.

A scaffold isn't finished when it's up. It needs a handover, an inspection at least every seven days and a record of every one. DuoApp puts jobs, inspections, handovers and CISRS cards in one app your inspectors and erectors will use - with CIS and invoicing handled properly.

Putting it up is the easy part.

Scaffolding is one of the most inspected trades on site, and most of it still runs on carbon-copy pads. These are the problems scaffolding contractors tell us about most.

Inspections slipping past seven days

With dozens of scaffolds across different sites, one missed inspection is all it takes - and you find out when the main contractor or HSE does.

Inspection records on carbon pads

Paper registers, rained-on and filled in from the cab. When someone asks for the history of a scaffold, it's in a box in the yard.

Handovers without evidence

Handover certificates with no photos, so when something is altered later, nobody can show what was handed over.

Adaptations and hire periods lost

Alterations, extra lifts and extended hire agreed on site are forgotten by the time the invoice goes out.

CISRS cards and tickets

CISRS cards, inspection courses and insurance expire, and nobody notices until a site manager turns someone away.

CIS and retention by hand

Deductions, retention and releases tracked in a spreadsheet, and the yard is always chasing money.

// How DuoApp helps

Built around how scaffolding contractors work.

Everything below is included in the same £10 per user, from the yard to the office.

Every site, scaffold and inspection in one view

Set up each scaffold as part of its job, and add inspections as recurring tasks every seven days or at whatever interval you need. The next one appears as soon as the last is done, and overdue inspections stand out.

  • Recurring inspections at any interval
  • Overdue inspections flagged
  • Erect, adapt and strike as tasks

Inspections and handovers with photos

Turn your inspection and handover checks into checklists on the phone, with pass, fail or N/A for each item, photos and a signature. Every record is timestamped and stored against the scaffold.

  • Pass / fail / N/A checks
  • Photos and signatures on every record
  • Works offline and syncs later

  • Expiry warnings for every card
  • Approval inbox for new documents
  • Ready when a main contractor asks

Adaptations agreed, not forgotten

Raise an alteration or extra lift from site on your phone, send it for sign-off and keep a full audit trail, so extra work turns into extra money.

  • Raised from site on a phone
  • Custom approvers per job
  • Full audit trail

CIS and retention, built in

Deductions, verification status, retention and releases sit on every invoice, so what you're owed and what you owe is always worked out for you.

  • CIS deductions and verification
  • Retention held and released
  • Split payments against real work
More on Retention & Deductions →

Price it the way you're paid

Fixed prices per scaffold or stage, split labour and materials, or your own subcontract gangs with staged claims - all on the same platform.

  • Labour and materials split
  • Subcontract gangs managed properly

  • Required-to-view designs and RAMS
  • Sign-off blocked until read
  • Re-locks on each revision

// Scaffolding FAQs

Questions scaffolding contractors ask us.

Can DuoApp schedule scaffold inspections every seven days?
Yes. Inspections are recurring tasks that can repeat every seven days or at any interval you choose. The next one appears as soon as the last is completed, or a set number of days before it's due, and overdue inspections are highlighted. You can add extra inspections at any time, for example after bad weather or an alteration.
Does DuoApp produce scaffold tags or handover certificates?
DuoApp records the handover and inspection itself - checklist, photos, signature and time - against the scaffold. It doesn't print scafftags, and there's no scaffold handover certificate template out of the box, but admins can build their own in Compliance & Certificates. If you use your own handover certificate or scafftag system, attach it to the job so everything sits together.
Does DuoApp handle CIS for scaffolding subcontractors?
Yes. CIS deductions, verification status, retention and split payments are built into invoicing as standard, not bolted on.
Does it work without signal?
Yes. Inspections and sign-offs work offline and sync when signal returns.
Is it suitable for a small scaffolding firm?
Yes. You pay £10 per user, per month, so a team of five costs £50 a month with every feature included. You can add and remove people as your team changes and you're billed pro-rata.
How much does it cost and is there a free trial?
£10 per user, per month plus VAT, with every feature included. There's a 14-day free trial of the full platform, and you can cancel any time from the billing screen.
