From timesheet to payment — construction management built for UK subcontractors
Valegrid Flow is all-in-one construction management software for UK contractors: CIS-native payroll, auto-generated RAMS, HAVS tracking, site diaries with timestamped photos, valuations & invoicing generated from timesheets, and AI drawing takeoff — from £19 per active worker per month.
The app runs at flow.valegrid.co.uk — your data stays in the UK product you sign up to.
Everything a UK site business runs on, in one place
One approval on a timesheet drives payroll, HAVS, valuations and the site record. No spreadsheets, no re-keying, no US software pretending it knows what CIS is.
CIS-native payroll
Verification-aware 20%/30%/gross deductions calculated straight from approved timesheets, with HMRC-ready CIS statements and exports. No re-keying into a second payroll tool.
Auto-generated RAMS
Risk assessments and method statements generated from reusable templates in minutes, tied to the project and ready to send before you're on site.
HAVS tracking
Hand-arm vibration exposure calculated automatically from timesheets and tool usage — HSE exposure points and A(8) without a single spreadsheet.
Site diaries that stand up
Daily diaries with timestamped photos, weather captured automatically, sign-offs, and PDF exports you can put in front of a main contractor or adjudicator.
Valuations & invoicing from timesheets
Weekly valuations and invoices built from the hours your team actually worked — retention, CIS deductions and the VAT domestic reverse charge handled correctly.
AI drawing takeoff & project assistant
Upload drawings and let AI extract areas and dimensions; ask the project assistant questions grounded in your own site records.
Fleet & compliance
Vehicles, mileage, plant and people compliance (CSCS, insurances, HAVS assessments) tracked in the same place as the work.
Built for UK subcontractors
Project Sync connects main contractors and subcontractors so timesheets, sites and areas flow between companies without double entry.
How Valegrid Flow works
- Step 1
Clock in on site
Workers clock in from their phone — GPS-stamped, in their own language, with voice notes on clock-out.
- Step 2
Approve once
Managers approve timesheets; payroll, HAVS, valuations and site records all update from that single approval.
- Step 3
Get paid
Valuations, applications and invoices generate from approved hours — CIS, retention and reverse-charge VAT applied per HMRC rules.
