UK construction.
UK builders.
UK software.
Unibuild Software is a UK-based company building one platform for UK construction SMEs. We started because the tools UK firms were using either came from the United States and ignored the regulatory backbone, or charged per helmet and punished firms for putting workers on the system. We think you can do better than that.
The story.
UK construction SMEs run on a stack of fifteen-odd applications glued together with WhatsApp, Excel, Sage, paper RAMS folders, and the goodwill of an office manager who stays late on Fridays. The cost of that mess — in admin chase, payroll leak, missed CIS deductions, and compliance evidence that does not survive an audit — is somewhere between £20k and £150k a year for a thirty- person firm. Most directors know it. None of them have the time to switch tools every Tuesday.
The tools that exist were not designed for this. The American giants — Procore, PlanGrid, Buildertrend — are expensive, priced per seat, and built for a market that has neither CIS nor CDM 2015 nor MTD reverse charge as first-class concepts. Per-seat SaaS punishes you for putting more workers on the system you bought to put workers on. Spreadsheets and paper do not survive an HSE letter.
Unibuild was started to do the unfashionable thing — write one platform that covers workforce, safety, sites, money, plant and comms, with UK regulation as the baseline rather than a localisation pass, priced as a flat quote rather than a headcount tax, and tested for adoption on a wet Tuesday on a real site rather than in a demo room. The site adoption test matters: if the labour gang will not pull the app out of their pocket, none of the rest matters.
Six principles that
shape everything we ship.
These are not posters in a meeting room. They are the filters that decide what we build, what we charge, and what we refuse to do. Every decision below has a one-line answer.
UK regulation is the baseline
CDM 2015, CIS, MTD with reverse charge, RIDDOR, LOLER, PUWER, COSHH, Working Time Regulations. Not bolt-ons. Not localisations. Built into the data model from day one.
FilterReg firstAdoption is the product
If the lads on site will not use it, the office cannot rely on it. Three taps for any flow. Glove-friendly, offline-tolerant, no app store, no password reset on a foreman's phone.
TestWet TuesdayUnlimited users, every plan
The whole point of consolidating onto one platform is that everyone is actually on it. We don't charge per helmet. The bill does not move when you add the labour gang.
PricingFlat quoteThe quote is the bill
Bespoke pricing based on what you use. Written quote in one working day. No setup fee, no migration fee, no premium tier. The figure on the quote is the figure on the invoice.
TrustNo fogUK-hosted, UK-supported
AWS eu-west-2 (London). Data does not leave the UK. Phone answered by someone in our UK office who has been on a site. No tier-1 ticketing in another timezone.
StackUK end-to-endBoring releases, on schedule
Tuesday and Thursday before 10am. Never Fridays. Every customer on the same build at the same time. No "enterprise edition" with the good bits behind a paywall.
CadenceTue / ThuSix lines we have
drawn and will not cross.
Every founder has a list of things they would do if someone offered them enough money. Here is ours, in public, so you can hold us to it.
Per-seat pricing
The whole platform falls apart the moment people are scared to give the foreman a login. The bill follows the firm, not the headcount.
StatusPermanentTiered features
No "Pro" plan that locks the audit trail behind a paywall. Same release for everyone, every Tuesday.
StatusPermanentManufactured testimonials
Named customer stories ship only with written consent. Anything illustrative is flagged "Illustrative". We will not pass an invented customer off as a real one.
StatusPermanentSelling your data
You own your data. We do not sell it, anonymise it for resale, or train models on it. UK GDPR, ICO registered, DPA on the standard contract.
StatusPermanentFriday releases
If it breaks on a Friday, the office is already in the pub. We ship Tuesdays and Thursdays before 10am, never on a Friday afternoon.
StatusOperationalOffshoring support
Calls answered in our UK office by a person who knows what a CIS deduction certificate is. No tier-1 ticketing queue, no chatbot pretending to help.
StatusPermanentA small team,
building this.
Unibuild is small on purpose. The founders write code, take support calls, and visit sites. The full leadership page is at /team/ — short biographies and how to get in touch directly.
