MCS 007: product certification for renewable equipment

MCS 007 is the Microgeneration Certification Scheme (MCS) standard that sets the product certification requirements for heat pumps, covering the testing and performance criteria a heat pump must meet before it can carry MCS certification. It is a product standard, not an installer standard. When most people say "MCS certified" they mean the installer, who is assessed by a certification body against rules such as MCS 001 and the technology installation standards. Product certification is a separate scheme that certifies the equipment itself, and an installation only counts as MCS-compliant when both are in place.

Product certification versus installer certification

MCS runs two parallel certification routes. The installer scheme assesses the company and the competence of the people doing design, installation and commissioning. The Product Certification Scheme assesses the physical products: the model of heat pump, solar panel, inverter or battery that goes on the roof or against the wall.

MCS describes its installation standards as defining how technologies should be designed and installed using MCS certified products. That wording matters. A fully certified installer who specifies equipment without valid product certification has not delivered an MCS-compliant installation, and the certificate and any scheme that depends on it can be at risk.

What MCS 007 covers

MCS 007 is titled Product Certification Scheme Requirements for heat pumps. It outlines the testing and performance criteria for heat pump products, and recent issues reference performance data such as seasonal efficiency (SCOP) values calculated under MCS 026. The standard has been revised several times, and newer issues carry future implementation dates, so check the current issue on the MCS Standards and Tools Library rather than relying on an old copy.

Other technologies, including solar panels and inverters, are certified under their own product standards within the same Product Certification Scheme. The principle is identical: the manufacturer proves the product meets the standard, and the product is then listed.

How installers check a product

MCS publishes a Product Directory that can be searched by technology type, certification status and certification period. Each listing shows a model number, a certification number and the dates the certification runs. Some entries are marked as being in a grace period, which means the certification period is ending and a transition applies.

Checking the directory is a quoting-stage task, not a handover-stage one. Product certification is time-limited, so a model that was listed when you priced the job may have lapsed by the time you install it.

> Tip: Record the certification number and certification end date against each product when you quote, then re-check the directory before ordering and again before commissioning.

Why it matters for quoting and stock

Product choices flow straight into the paperwork. Specifying a panel, inverter or heat pump that is not currently certified can mean the installation cannot be registered as MCS-compliant, which in turn can affect customer grants and finance. The cost of correcting it is usually a swap of equipment after the fact.

Installers who offer several certified options for the same system find this easier to manage. Building each system as a bundle of known, certified components keeps the specification consistent across quotes, which is what kits and variants do for a product catalog, and a quote that lists the exact model numbers gives the customer and the office a single record to check.
