R0021 & R0101 were implemented in Code on 30 June 2023, as part
of the June 2023 Retail Energy Code (REC) Release, to support the
introduction of Safe Isolation Providers (SIPs). Additional
information was needed from Distribution Network Operators (DNOs),
Suppliers & Metering Equipment Managers (MEMs) to support the
interim solution between 30 June 2023 and 03 November 2023.
SIPs have the ability to carry out de-energisations and
re-energisations to support the installation of Isolators or Low and
Zero Carbon Technology (L&ZCT) equipment, including Electric
Vehicle Charging (EVC) Points. Property owners are able to contract
directly with SIPs to carry out this work, without needing to identify
and make arrangements directly with all the individual Suppliers who
have meter points at the property. All SIPs must be accredited MEMs,
which means that they already have the technical skills, audit
framework and industry systems necessary to carry out this role.
When SIPs attend a property to carry out work on other Suppliers'
meters, they may come across a number of scenarios that they will need
to notify to other parties, through changes to (and the introduction
of one new) Market Messages:
- Notification to DNOs (as defined in the Guidance for Service Termination Issue
- Immediate Danger relating to
DNO equipment (e.g. cut-out)
- Damage to DNO equipment
- Notification to Suppliers
- Immediate Danger relating to Supplier equipment (e.g.
- Damage to Supplier equipment (e.g. meter)
- Suspected Interference / Tampering
- Site left
de-energised (or later re-energised)
- Smart comms
cannot be re-initiated
The solution was developed in collaboration with the Distribution
Connection and Use of System Agreement (DCUSA) Working Group for DCUSA
Change Proposal 394 (DCP394) and includes the changes required to the
REC to cover all of these scenarios, as well as the introduction of
the SIP role itself.

de-energise and re-energise supply points independent of the Supplier"
Raised in December 2021, this Change
Proposal recognised that there was no ability for premise owners
to request that a single MEM completes work on multiple properties
that may have different Electricity Suppliers. This created barriers
to developing solutions for local authorities, private and social
housing landlords who are refurbishing premises or to help any premise
owner (whether domestic or non-domestic) install new equipment to
facilitate L&ZCT such as the retro-fit of EVC Points to homes and
This Change Proposal was raised to create a new role - a Safe
Isolation Provider (SIP) - that will enable MEMs to accept
instructions to undertake a limited set of activities at the
request of the premise owners without the need to use the Registered
Suppliers’ MEMs. A consultation was circulated on 12 July 2022 to
obtain views on the Preliminary Change Report and R0021 was
subsequently approved by Ofgem
on 08 December 2022 for implementation on 30 June 2023.

and approved solution for R0021"
Raised in March 2023, this Change Proposal was required to clarify
the intent and mechanisms required to support R0021, following a webinar
Parties on 02 March 2023 in which a number of questions were
raised about the solution. A further webinar
was hosted on 09 May 2023, during the Consultation period for
R0101, to ensure that Parties had the opportunity to clarify any final
questions, to enable them to respond to the Consultation. R0101 was
subsequently approved on 26 May 2023 for implementation on 30 June 2023.
Manager recognised that the approval of R0101 on 26 May 2023 and
publication of the Pre-Release on 30 May 2023 gave limited opportunity
for Parties to prepare for the implementation of these changes. As a
result, R0101 introduced an interim solution option for DNOs and
Suppliers who may not have been able to deliver the required changes
to Market Messages in full by 30 June 2023. It enabled a manual,
interim solution to be adopted for the relatively low volume of
notifications to DNOs and Suppliers (of danger, damage and
interference) that was expected between 30 June 2023 and 03 November 2023.
MEMs who intended to carry out any work as a SIP must have
implemented the solution in full, at the time that they want to start
carrying out approved activities as a SIP.
All Parties needed to have implemented the full, automated
solution, by 03 November 2023.
For any SIP activity carried out between 30 June 2023 and 03
November 2023, the interim solution required SIPs to determine whether
or not any affected DNOs or Suppliers were able to receive relevant
updates via Market Messages or whether they needed to contact them
with updates by telephone instead.
Since the interim solution required Parties to communicate by
telephone, the Code Manager agreed to host the relevant information
within the Metering Hub on the REC
Portal. SIPs could refer to the information hosted there to enable
them to determine which DNOs and Suppliers needed communications by
telephone (rather than Market Messages) and when each DNO and Supplier
planned to be in a position to receive Market Messages. It also
provided SIP contact details to enable DNOs & Suppliers to contact
them with any necessary updates in response to the notifications that
they received from the SIP.
