Business Protection & Verified Reputation Infrastructure · UK Trades & Construction
Stop losing money on disputed jobs
SigBond gives you a co-signed, verifiable record of what was agreed — confirmed by your client before work begins. If anything goes wrong, export a court-ready PDF in one click. No more word-against-word.
Every handshake agreement is a liability. Every unverified review is noise. The trust infrastructure for real-world transactions does not exist.
£7K+
Average annual cost of disputed jobs
A disputed kitchen refit. A client who vanishes after phase one. Scope creep with no written record. UK trades and construction has the worst payment culture of any industry — yet contractors have no tools to protect themselves.
7.8M
Fake reviews removed
Trustpilot removed 7.8 million fabricated reviews in 2025 alone — a 73% increase year-on-year. AI-generated content is making fabrication cheaper and harder to detect.
Bad-faith clients are invisible
Tradespeople have no way to verify whether a prospective client pays on time, communicates clearly, or has a history of disputes. They take on financial risk blind.
Reputation is platform-locked
Your Google reviews, Trustpilot score, and Checkatrade profile belong to those platforms — not to you. Switch platforms and your reputation starts from zero.
How It Works
Protection first, reputation follows
SigBond uses cryptographic infrastructure — invisible to the user, powerful underneath — to create records that can't be faked, altered, or denied.
01 — Sign Up
Get your verified identity
Sign up with email. Behind the scenes, SigBond generates a cryptographic keypair — your verifiable digital identity. You never see or handle keys. It's invisible infrastructure, like encryption in WhatsApp.
02 — Create a Verified Record
Both parties co-sign at job start
At the point of agreement, both parties co-sign a verified record — job title, scope, price, dates. Your client receives an SMS, views the terms, and taps Confirm — under 15 seconds, no account needed. All detail is stored securely off-chain; only a cryptographic fingerprint publishes to the network. This is your protection — captured when engagement is highest, not after the work is done.
03 — Build Reputation
Both sides review each other
After the work is done, both parties submit reviews held in escrow — neither can see the other's until they commit their own. Every review links to a verified transaction. No transaction, no review.
Two-Sided Value
It works because both sides benefit
SigBond is not "something the contractor uses." Both parties get tangible, immediate value.

Timing
Regulation is creating the demand
UK trades and construction is facing a wave of compliance requirements. Verified records have never been more valuable.
1 May 2026
Renters' Rights Act
The biggest reform to England's private rented sector in decades takes effect on 1 May. Safety compliance is now a prerequisite for landlord possession orders. One expired gas certificate can block a landlord from regaining their property. Verified compliance records have never been more valuable.
Late 2026
PRS Database
Every private landlord in England must register and upload safety certificates to a national database. Penalties up to £40,000 for non-compliance. Creates statutory demand for digitally verifiable compliance records.
Ongoing
Warranty verification gap
Boiler manufacturers require annual servicing to maintain warranties of up to 12 years but have no mechanism to verify services occurred. SigBond attestations provide cryptographic proof for instant warranty claim verification.
