Ventilation Commissioning Certificate (Building Regs Part F)

A ventilation commissioning certificate records that a mechanical ventilation system has been installed and commissioned so that its measured airflow rates meet the requirements of Building Regulations Part F. It applies to systems such as intermittent extract fans, mechanical extract ventilation (MEV) and mechanical ventilation with heat recovery (MVHR).

Part F sets minimum ventilation performance, and commissioning is where measured airflow rates are checked against those requirements. The commissioning work is notifiable, so producing a clear record is an important part of demonstrating compliance.

TradePlanr lets you record the system details and measured airflow rates on site, compare them against the Part F requirements and produce a PDF commissioning certificate for the customer and building control.

What it covers

  • The property address and client or responsible person details
  • The installer and commissioning engineer details
  • The ventilation system type, for example intermittent extract, MEV or MVHR
  • Measured airflow rates at each terminal or point
  • Comparison of measured rates against the Part F requirements
  • Confirmation the system has been commissioned correctly and any notes
  • Commissioning date and signature

When it's required

A ventilation commissioning certificate is completed when a new mechanical ventilation system is installed and commissioned. Commissioning is where the measured airflow rates are checked against the Part F requirements to confirm the system performs as intended.

Because the commissioning of mechanical ventilation is notifiable under the Building Regulations, a completed record supports demonstrating compliance to building control, whether through a competent person scheme or a building control application.

Keeping the certificate on file gives the customer evidence the system was set up to meet Part F, and provides a baseline of airflow readings that is useful for any future service or fault-finding.

How to issue it in TradePlanr

  1. 1

    Enter property and system details

    Record the property address, installer details and the ventilation system type, such as intermittent extract, MEV or MVHR.

  2. 2

    Record measured airflow rates

    Capture the measured airflow rates at each terminal or point so you have the readings needed to assess performance.

  3. 3

    Check against Part F requirements

    Compare the measured rates against the Part F requirements and confirm the system meets the required performance.

  4. 4

    Sign and store the PDF

    Add the commissioning date and your signature, then generate a PDF certificate for the customer and building control.

Frequently asked questions

What is a ventilation commissioning certificate?

It records that a mechanical ventilation system has been commissioned and that its measured airflow rates meet Building Regulations Part F. It covers systems such as intermittent extract, MEV and MVHR.

Is ventilation commissioning notifiable?

Yes. Commissioning of mechanical ventilation is notifiable under the Building Regulations, so a completed commissioning record supports demonstrating compliance to building control.

Which systems need Part F commissioning?

Mechanical ventilation systems including intermittent extract fans, mechanical extract ventilation (MEV) and mechanical ventilation with heat recovery (MVHR) are commissioned against Part F airflow requirements.

Can I record airflow readings on site?

Yes. TradePlanr lets you record measured airflow rates, compare them against the Part F requirements and generate a PDF certificate on your phone or tablet.
