Somewhere between the offer and the exchange, a buyer's solicitor will ask what has been done to the house. When was the boiler last serviced. Who rewired the kitchen. Was the roof work signed off by anyone.
Most sellers answer from memory, then spend an evening looking for a receipt.
Why the answer matters more than the work
A seller who says "yes, annually" and produces nothing is asking to be trusted. A seller who produces a dated record is answering a question. The second one costs the buyer nothing to check, which is exactly why it moves faster.
That difference shows up in the parts of a sale nobody budgets for: the week waiting on an enquiry, the survey that flags something you already fixed, the renegotiation that starts because a question went unanswered rather than because anything was wrong.
Not all evidence is equal, and the record should say so
A photo of a boiler is not the same as a service record from a Gas Safe engineer. Something the owner typed in is not the same as a job completed through a vetted trader.
Every entry on a HomeLynx Passport carries an evidence grade for exactly this reason. Verified, recorded, unconfirmed. The grades are explained on a public page, so a buyer can see what each one means without taking our word for it, and entries are tamper-evident and timestamped, so an entry cannot be quietly rewritten later to look better than it was.
An honest record beats a flattering one, because a flattering one falls apart at the first question.
Where to start
You do not need a complete history to start having one. Add what you know, attach what you can find, and let the work you have done from now on record itself.
Property-history reports are free for signed-in users, and what a report shows is governed by your sharing consents. You decide who sees it and when.
If you would rather look before you commit to anything, there is a sample passport at tradelynx.co.uk/demo/homelynx-passport. It is the real interface running on sample data, and it says so.
