First Fix to Final Cert — Built into Your Programme.
First fix runs to your stud-up schedule, not the other way around. We coordinate cable routing with plumbing and HVAC at design stage so trades don't trip over each other on site. Second fix lands the week before snagging. Test, certify, and hand over the RECI compliance pack on the day before completion.
