Changes to MCS installation standards for heat pumps
Effective from 31 July 2017, the Department for Business, Energy & Industrial Strategy (BEIS) introduced a change to the Domestic RHI Regulations to reflect the latest version of the Microgeneration Certification Scheme (MCS) installation standard for heat pumps.
Version 5.0 of MIS 3005 of the MCS standards was introduced by MCS on 28 April 2017; taking effect from 17 May 2017. From 30 October 2017 onwards, heat pumps must be installed in accordance with this version of the MCS standards.
Please see our changes to the scheme webpage for more information.
Please ensure you are up to date on the latest standards.
Installer eligibility criteria in the Domestic RHI
Your installation company must be a Microgeneration Certification Scheme (MCS)open key term pop-up member. When dealing with domestic customers, you must comply with the Renewable Energy Consumer Code (RECC)open key term pop-up or the Home Insulation and Energy Systems Scheme (HIES) code of practice.
It's acceptable for the heating system installed for your customer to be a first installation for which you're accredited under MCS, as long as you can issue an MCS certificate for it.
Getting to grips with the scheme
You can find everything you need to know in the Essential Guide for Installers but it’s also worth you reading the Essential Guide for Applicants too. If you’ve read these and you’re still a little unsure about something, do get in touch.
You may want to help your customers through the process, providing them with the relevant information and evidence. Unlike the Non-domestic RHI, we ask that the customer submits the application, not the installer.
They’ll need to give personal information, including the bank account into which we make payments and also an email address through which we can contact them directly. It’s important that we get this email address correct as we use it to send out reminders for customers to sign their annual declarations and to get in touch if there’s any issue with their account.
Your customers will need the following documentation. The more information you can give them upfront, the smoother the application process will be.
- an MCS certificate (within 10 working days of the commissioning date)
- an MCS compliance certificate (and where the MCS installation number is on it)
- an EPC that is less than 24 months’ old
- an itemised invoice showing parts and labour
- the completed Installer Metering Questions document for biomass or for heat pumps (only if the heating system need to be metered). There's also an Alternative Metering Arrangements document for biomass or for heat pumps, if required.
- advice on the heating system’s maintenance, servicing and efficient use. This is because your customer must keep the heating system in good working order throughout their seven years on the scheme. You should also explain what actions might invalidate the warranty
- Advice on how to use and read meters (if they need them).
Some applicants need to provide additional evidence:
Registered social landlords making their first application need to provide:
- their organisation’s registration number
- the registered name and address
- a letter of authorisation for their authorised representative.
Where the property has to be metered, your customer will need to provide additional information about their metering arrangements which they get in documents from you. See Installers and metering.
There are some cases where your customers will come into review with us and will have to provide additional evidence. For an example of why this might happen, and what evidence we’ll require, have a look at our ‘I’m in review’ Helpsheet.
In some cases your customer’s application is with our compliance team, who are asking for additional evidence of compliance with the scheme rules. As part of these checks we may review a large number of applications from a single source. For example immediately before a biomass degression we may review all applications by the customers of a number of biomass installers.
