Certify It

Protect Your Home, Finalise with Confidence

Get the knowledge and structure to close out your project properly, safeguard your investment, and create a complete home manual.

"The final stage of any project is often the most overlooked, but getting it right is essential. Certify It helps you protect your investment, tie up loose ends, and set your home up for long-term success."


— Oliver Steele-Perkins

Certify it is for self builders and homeowners who:

  • are nearing the end of their project and want to close it out properly

  • unsure what’s required for certification, warranties, and handover

  • looking to understand the final steps and sequencing before completion

  • to avoid loose ends that could cause issues later

  • wanting a complete Homeowner Manual with all documentation in one place

If you're nearing completion and want to complete the project cleanly and professionally Certify It is designed for you.

Why Certify It?

Many homeowners reach the end of their build without a clear process for sign-off, final accounts, or organising documentation, leaving loose ends that can cause future problems.

Certify It ensures you finish strong, with everything wrapped up professionally and nothing overlooked. It gives you the structure and support to:

✔ Protect your investment: Ensure warranties, certificates, and approvals are in place


✔ Avoid future headaches: Get your documents, manuals, and paperwork fully organised


✔ Close the books: Manage financial retentions, settle the final account, and manage defects properly


✔ Move forward with confidence: Know that your home is compliant, covered, and ready to live in

What Certify It helps you do

Final sign-off isn’t just a formality, it’s what protects your home, your investment, and your peace of mind. This phase brings everything together, ensuring the paperwork is complete, accounts are settled, and you’re ready to move in and enjoy your home knowing that all the paperwork is up together.

Certify It is supported by the Essentials Workspace, where you can track sign-offs, gather your documents, and manage the final account with ease.

Step 1

Final Sign-Off & Certification

Everything you need in place to legally and formally complete your project and secure final approval.

  • Completion Certificates and testing. Organising electrical, plumbing, ventilation, commissioning and compliance documentation.

  • Building Control sign off: Managing final inspections, declarations, and the sequence required for completion certification.

  • Structural Warranty close out: Coordinating final inspections and warranty sign-off alongside Building Control approval.

Step 2

Financial Close-Out

Closing out the final account and protecting your financial position after construction.

  • Final accounts: Reviewing completed works against payments made and agreed scope.

  • Retentions: Understanding when funds should be released and what should remain outstanding.

  • Practical Completion: Managing completion, reducing disputes, and closing out remaining snagging items properly.

Step 3

Home Operation and Maintenance Manual

Keeping your project information organised so your home remains protected long after completion.

  • What your O&M manual should include: Certificates, warranties, maintenance information, finishes schedules, and key handover documents.

  • Live project records: Using structured templates to organise and store important project documentation within the Essentials Workspace.

  • Protecting your home: Why accurate records matter for maintenance, future works, insurance, and resale.

Step 4

Defects Period & 12-Month Review

Managing post-completion issues professionally and protecting your position after handover.

  • Understanding the defects period: What remains the contractor’s responsibility after Practical Completion.

  • Managing outstanding items: Tracking unresolved defects and ensuring issues are formally addressed.

  • 12-month review and retention release: Preparing for final inspections, sign-off, and release of retained funds.
