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

One approval carries the work all the way through — hours on site flow straight into an approved timesheet, and out the other end as a paid invoice.

  1. 1
    Step 1

    Clock in on site

    Workers clock in from their phone — GPS-stamped, in their own language, with voice notes on clock-out.

  2. 2
    Step 2

    Approve once

    Managers approve timesheets; payroll, HAVS, valuations and site records all update from that single approval.

  3. 3
    Step 3

    Get paid

    Valuations, applications and invoices generate from approved hours — CIS, retention and reverse-charge VAT applied per HMRC rules.
