About MCS

MCS is a mark of quality and demonstrates
compliance to industry standards that companies
strive to meet. It highlights to consumers that
companies are able to consistently install or
manufacture to the highest quality every time.

MCS has become aware of a failure with regards to the Evoco Energy 10kW wind turbine. Evoco Energy have issued a press release which is detailed below. MCS is liaising with relevant parties to co-ordinate the response to the situation and further updates will be posted here. Further details may also appear on Evoco Energy’s website

If you are a customer who has had one of these wind turbines installed, Evoco Energy issued out a request to apply the brakes to all turbines whilst they implemented measures to address the problem. Although the brake request had been issued, three incidents occurred and modifications are currently being deployed to all turbines to increase the safety margins in the Evoco design.

If you have any questions please see the FAQs below or alternatively speak to your installation company. Installation companies are then in turn advised to contact Evoco Energy or their certification body for further guidance.


Q) Will consumers receive compensation if the Evoco turbines are withdrawn from the MCS?

A) Evoco 10kW turbines are currently advised to be put on brake and it is not currently clear whether it will be withdrawn from the MCS scheme but should that be the case, consumers will be given information on the courses of action open to them in seeking redress.

Q) How will the failure of the Evoco turbine affect the wider MCS scheme?

A) The failure of Evoco turbine does not affect the MCS scheme. MCS covers the full range of microgeneration technologies and will continue to provide a certification service for microgeneration technologies and consumers. 

Q) Why did MCS certify a small wind turbine which has subsequently failed?

A) The MCS tests and certification of wind turbines are robust and follow international and European standards. Certification cannot guarantee that products will not fail but it does give greater assurance. At this stage it is unclear why the products failed and we therefore await further information about the situation, however, an initial report suggests that the site could have experienced exceptionally high wind speeds in excess of 120mph which significantly exceeds normal wind speeds.

Q) Does this wind turbine failure affect those consumers who have installed the Evoco 10kW turbine and are receiving feed-In Tariffs?

A) Until further investigations are completed into the technical problem facing the Evoco 10kW turbine, it is unclear what the affect will be on Evoco customers currently receiving Feed-In Tariffs. However, as we are advising users of the Evoco turbine to put them on brake, they will be unable to generate electricity which consequently will have an impact on the Feed-In Tariffs as the tariff is based on electrical generation. Evoco has stated that they will pay their customers compensation whilst the turbines are on break.

Q) What should I do if I have purchased an Evoco turbine but not yet had it commissioned?

A) You should contact your MCS certified installation company for further information and not turn it on until the installation company have been informed that it is safe to do so.
