From first drawing to final profit — construction management built for UK contractors and subcontractors
Hours of admin, gone
One timesheet approval runs payroll, HAVS, valuations and the site record — no re-keying.
Get paid faster
Valuations, applications and invoices generate straight from the hours your team worked.
No CIS or VAT headaches
CIS deductions and the VAT domestic reverse charge applied automatically, to HMRC rules.
VALEGRID FLOW is all-in-one construction management software for UK contractors, built on zero double-entry: your crew's hours are typed once, at the gate, and everything the week owes comes out of that one approval — CIS-native payroll, HAVS tracking, site diaries, valuations and invoices. Add auto-generated RAMS and AI drawing takeoff, from £29 per month. It runs the whole job end to end: price it from the drawing, win it, and watch the same budgets you priced burn in real time as your crew books hours.
The app runs at flow.valegrid.co.uk — your data stays in the UK product you sign up to.

Price it. Work it. Bill it. Nothing typed twice.
Flow runs the job end to end. Upload the drawing and AI splits it into areas. Price each area and the tender builds itself. Win the job and that estimate becomes the live budget — then every hour your crew clocks on site burns the same areas you priced. You see the profit from day one, not at the final account, and Flow warns you the moment a job starts to drift.

Everything a UK site business runs on, in one place
Zero double-entry, right across the job: 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.
QR sign-in at the gate
One poster on the site cabin: workers scan to clock in with GPS, price-work gangs sign in by name with no app, and visitors complete the legal register — with a live 'on site now' board and automatic sign-out for anyone who forgets.
Estimating & tenders
A tender pipeline with rate libraries, assemblies and cost memory from your own past jobs — AI flags missing items and rates that look off, and a won tender becomes a live project in one step.
AI drawing takeoff & project assistant
Upload drawings and let AI extract areas and dimensions — and compare revisions to tell you what changed; 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.
Contractors & subcontractors, connected
Project Sync connects main contractors and subcontractors so timesheets, sites and areas flow between companies without double entry.
Labour agencies & workforce
Supply gangs to main contractors and both sides see the same truth: workers clock in by QR with GPS in 16 languages, approved hours and reports mirror to the contractor through Project Sync, and the live on-site board shows who's on which site right now — with CIS payroll handled on your side.

How VALEGRID FLOW works
It isn't a chain of steps — it's one approval. Hours land by themselves as your crew clocks in at the gate. The supervisor approves the timesheet once. And payroll with CIS, the HAVS record, the valuation, the invoice, the site diary and the area budgets are all built from that same approved week — nobody types it twice.
Frequently asked questions
- What is Valegrid Flow?
- Valegrid Flow is UK construction management software with CIS-native payroll (and full PAYE for employed staff), auto-generated RAMS and HAVS tracking, QR sign-in at the gate for workers, price-work crews and visitors, site diaries, estimating & tenders, valuations & invoicing from timesheets, fleet & compliance tracking, an AI project assistant, and AI drawing takeoff. It runs the job end to end: AI reads your drawings into areas, you price each area to build the tender, and once won the estimate becomes the live budget your crew's hours burn down in real time — with warnings when a project drifts. Built by a subcontractor, with straightforward flat pricing.
- How much does Valegrid Flow cost?
- Four flat plans: £29/month sole trader, £149 small crew (up to 10 workers), £499 contractor (up to 50), enterprise agreed above that. Fleet and Project Sync are on every plan; Small crew adds payroll with CIS. Every account starts with a 14-day free trial.
- Does Valegrid Flow handle CIS deductions and the VAT reverse charge?
- Yes. CIS deductions (20%, 30% or gross status) are calculated on the labour element per HMRC rules, and invoices apply the VAT domestic reverse charge with the correct wording, including the amount the customer must account for to HMRC.
- Who is Valegrid Flow for?
- UK subcontractors and small-to-mid contractors who run labour on site: groundworks, brickwork, carpentry, M&E and general builders — and labour agencies supplying workforce to main contractors, who use Project Sync to share hours and reports and watch the same live on-site board. It was built in the UK by a working subcontractor who needed it himself.
