Important notice

Switchee has identified a safety concern regarding the Power Supply Units (PSUs) for the MCO A8 air quality sensors in your home. A small number of these PSUs have failed in a way we consider unsafe.

Your safety is our top priority. We are taking immediate action to deactivate all affected PSUs and offer free replacements, despite the low failure rate and relatively low risk.

If you have one of these sensors (pictured) installed, please immediately turn it off and unplug it from the wall. Unplugging the unit completely eliminates the chance of this failure occurring.

We are working closely with your housing provider to mitigate this issue, and mutually agree on the approach for replacing the affected equipment. Please note - this will not have any impact on your heating and hot water, and we would recommend that any issues relating to this are reported to your housing provider.

We understand, and apologise for any concern or inconvenience caused. If you have any questions, please reach out to Switchee Support on 0800 133 7957.
