Sell or buy your home for free. Add a £75 AI co-pilot when you want it.

PropXchain is the online way to sell or buy a home in the UK. Start free on the Starter tier: pick your own providers and see every price before you commit — there is no platform fee. The optional £75 Premium AI co-pilot reads your HM Land Registry title and search results in plain English, flags what matters, and tailors your conveyancer quote to the real complexity of your transaction. Conveyancers on the CLC-verified panel join free and quote each job per transaction from a pre-assembled brief: HMLR title pulled, searches returned, and any enquiries surfaced by AI document review. Every milestone is recorded on the Internet Computer blockchain and visible in real time to seller, buyer, conveyancer and estate agent.

Why UK conveyancing is broken

  • 20–24 weeks to complete on average. Most of it spent waiting for solicitors to chase each other.
  • £1,500–£2,500 average seller cost, most of which is admin work rather than legal work.
  • 30%+ of transactions collapse before completion, largely because buyers and sellers have no visibility.
  • Zero real-time visibility:all information flows through solicitors who chase each other while you wait.

How PropXchain works

  1. Add your property:list the property on-chain in minutes.
  2. Complete your forms:guided TA6 (Property Information) and TA10 (Fixtures and Fittings).
  3. Order your searches yourself (local authority, drainage, environmental): pick your own provider and see the price before you commit.
  4. Everyone sees the same view:seller, buyer, conveyancer, estate agent share one live transaction.
  5. Exchange and complete through your conveyancers. PropXchain records the exchange and never holds your money.

What PropXchain does

  • Immutable audit trail on the Internet Computer.
  • HM Land Registry direct via the Business Gateway; title checks and registration in one place.
  • AML and KYC in one step via a regulated provider.
  • GDPR-compliant documents:only SHA-256 hashes go on-chain, never the documents themselves.
  • Instant milestone alerts by email and in-app.
  • Your money stays with the professionals:PropXchain never holds client money; completion funds move between the conveyancers.
  • Oscar AI assistant guides you through each step and analyses documents.

Frequently asked questions

How much does PropXchain cost?

Starting is free — you run your own transaction and see every provider's price before you commit, with no platform fee. The optional £75 Premium AI co-pilot reads your title and searches in plain English and tailors your conveyancer quote.

Is the blockchain audit trail legally valid in England and Wales?

Key events are recorded on the Internet Computer. Only SHA-256 hashes of documents are written to the blockchain, never the documents themselves. Contracts are signed and exchanged by your conveyancers in the usual way, which is what gives the exchange its legal effect.

Does PropXchain connect to HM Land Registry?

Yes. PropXchain is integrated with HM Land Registry's Business Gateway, so title checks, official copies and registration of dealings happen inside the platform.

What about money laundering (AML) and identity (KYC) checks?

AML and KYC checks are handled in a single step via a regulated provider.

Is there a platform fee?

No. Buyers and sellers both use the Starter tier free, paying their own providers direct. The only optional charge is the £75 Premium AI co-pilot.

Which blockchain does PropXchain use?

The Internet Computer Protocol (ICP). There is no gas fee for users.

Does PropXchain replace my solicitor?

No. PropXchain is the coordination and verification platform. You still instruct a regulated conveyancer or solicitor; PropXchain simply removes the admin overhead so they can focus on legal work.
