Not sure about the different types of ventilation systems? Find out how they work and the minimum required ventilation requirements here, or ask us!

Selecting the correct ventilation rate is only part of complying with Part F of the Building Regulations. In some cases trickle vents, under-cutting of doors, fan placement and other requirements are necessary to comply. You can familiarise yourself with Part F here to ensure you comply. The Elta Trade Ventilation Rate Caluculator was correct at the time of publication and we try our best to keep it up to date, however, requirements can change, so we recommend always confirming the ventilation rates in Part F yourself. As we cannot see the place of installation and are not system designers, the rates we recommend are only recommendations and not substitutes for a correctly designed system. No two installations will be the same. With this in mind, we cannot be held responsible for incorrect selections and installations.
