Air flow rates of ALL mechanical ventilation fans should be tested.
Including:
All extraction readings MUST be submitted to building control
A certificate stating the recorded rates MUST be left with the property owner
All ventilation rates should be tested using the correct UCAS accredited flow test instrument in accordance with Building Regs Part F

An unbalanced system can substantially reduce the heat recovery rate in a mechanical ventilation with heat recovery system (MVHR).
When commissioned the overall ventilation level of the MVHR unit is set to reflect the designed values for the nominal ventilation level. Also, when the system is balanced, the extract flow rate is adjusted to be the same as the supply flow rate. Balancing the system is important to ensure that there is no overall positive or negative pressure in in the dwelling. Each room inlet and outlet valve(s)also needs adjusting to the required levels of airflow, so that the rooms have enough fresh air being supplied or stale air extracted. The commissioning requires specialist equipment, such as a vane anemometer.
We use UCAS accredited flow test instruments for accurate measurements.
This is now a Building Control requirement under Approved Document F 2010 (2021 edition) of the Building Regulations.Which came into effect on 15 June 2022 for use in England.
Please contact us if you need a MVHR system commissioned.
To commission an MVHR system it is required to measure and record the air flow rates in each room using an anemometer. Minimum ventilation rates as set out in the Part F Document of Building Regulations are required to be met. When we commission MVHR systems we ensure that these flow rates are met and that the whole system is balanced and working efficiently. We also check other items such as the condensing pipe, filters, the external vents and the pipework and installation in general. Once we have balanced, commissioned and recorded the flow rates of the MVHR system we will then provide a Part F Document which can be issued to Building Control.
Please contact us if you need a MVHR system commissioned.
It is essential to ensure mechanical extract ventilation (MEV) systems are adequately removing the stale air only and are set at the correct extract rates to achieve this. This will maintain a good level of indoor air quality and ensure condensation and mould issues do not present themselves in your property.

These are mechanical extract ventilation that doesn't run continuously and are common in wet rooms such as bathrooms, toilets, utility rooms and kitchens.
These need to be used in conjunction with background ventilators

A PIV unit will provide a constant supply of fresh filtered air creating a positive pressure in the home.
Positive input ventilation units need setting up according to the manufacturers requirements and recommendations. This will ensure these units put the dwelling under the right amount of positive pressure to enable the removal of the stale and humid air.
This will maintain a good level of indoor air quality and ensure condensation and mould issues do not present themselves in your property.
Please contact us if you need a PIV system installed or set up correctly.
