“Further to our letter sent out on17th October 2012 to all MCS registered Solar Thermal Installers, MCS has now completed an initial review of the thermodynamic product type (including solar thermodynamic panels), and as a result, MCS has now taken the decision to temporarily suspend the registration of solar thermodynamic products within the MCS installation database until requirements for the installation of this product type can be developed by the Scheme. To be completely clear, this decision does not mean that the products cannot be installed in the UK, simply that they cannot be registered within the MCS installation database. This is not a decision that has been taken lightly and the reasons for temporarily suspending the use of these products are: 1. The performance of the products being installed in the UK cannot be fully determined; this is mainly due to the fact that these systems are being installed using refrigerant but the 12975 testing and certification through Solar Keymark did not use refrigerant as the heat transfer medium. 2. Systems with a compression heat exchange unit are unable to meet the requirements for completing the SAP and performance estimation calculations required under MCS, i.e. hybrid type systems are not covered fully within the SAP methodology which is required to be completed under MCS. 3. It is not clear how compliance with Part G of the building regulations is fully met, due to the system’s packaged control strategy. Installers are required to meet all parts of the building regulations under MCS, and it is uncertain if installers are able to do this within the system’s packaged control strategy. 4. It needs to be determined if the classification of these systems within MCS are actually Solar Thermal systems or if they should be classified as Heat Pump systems. Installation companies with contracts with customers in place prior to the date of this letter (5th November 2012 ) for the installation of such systems will have until18th November 2012 to register completed installations within the MCS installation database. From19th November 2012 , no further installations will be allowed to be registered within the MCS Installation database, and the product will be unavailable for selection. MCS is already working with a number of manufacturers to develop the requirements either by extension to the existing MIS 3001 or MIS 3005 or a brand new Scheme document if appropriate.”
“… if a decision-making body is to exercise powers such as those of serving an intervention notice without giving anybody the opportunity to make representations beforehand, its procedures should provide that those who might otherwise expect to have been allowed to make representations should at least be allowed to make immediate application to set the decision aside and to appeal against it. In this respect the situation is very similar to that which obtains when the court grants an ex parte injunction”
