Recording past work: setting up a Passport retrospectively

31 August 2026 · 5 min read

How to build a property record for work completed years ago, including where to find missing certificates and approvals.

Most homes already have a history: an extension in 2016, a new boiler in 2021, rewiring somewhere in between. You do not need a live project to start recording, and reconstructing the history is usually easier than people expect.

Where records tend to be found

  • Your local authority's online planning register, which often holds decision notices and drawings
  • Building Control records held by the council or the approved inspector used at the time
  • Competent person scheme registers for electrical, gas and window installations
  • The conveyancing pack from when you bought the property
  • Old email accounts, invoices and bank statements that identify the contractor

Record what you know, flag what you do not

A record marked as incomplete is far more useful than no record. Note the work, the approximate date, the contractor if known, and which documents are missing, then fill the gaps over time.

In Project Passport you can create a project retrospectively, so completed past work is recorded as history rather than as a live build, and the checklist shows what is still outstanding.

Project Passport keeps these records together in one permanent digital record of your property, so the drawings, approvals, certificates, warranties and photographs of every project stay findable years after the work finishes. It is an independent record-keeping platform: it complements, and does not replace, Building Control, HM Land Registry, conveyancers or professional advice.

Keep the record

Every project. One passport.

Keep drawings, approvals, certificates, warranties and photographs together in one permanent digital record of your property.
