It would only be considered a
building service if the Internet
connection is considered
critical to the energy
performance of the building,
(e.g. via Google Nest).
No, it cannot. This may result
in withdrawal of funding (e.g.
from ECO), under which non compliance is not negotiable.
It is the Retrofit Coordinator’s responsibility to ensure the design is compliant. Retrofit Coordinators are responsible for managing risks as effectively as they can be managed. They should use their judgment to evaluate whether proceeding with a design will achieve the intended outcomes or leave an unacceptable level of risk. Should that risk outweigh the benefits of proceeding, the Retrofit Coordinator should advise the client that the project should not proceed. It is not possible to completely eliminate risks. They should be mitigated as far as possible, then managed
Yes, several designers may
work together; however, one
must be the Lead Designer
who is able to sign off the
whole design solution.
PAS 2035 states the role of the Retrofit Coordinator shall be to protect both the
client’s and the public’s interest. Therefore, a Retrofit Coordinator may be employed
directly by the Client, or by an organisation commissioned to undertake assessment,
design, installation, commissioning or monitoring. Where a conflict of interest
arises between the Coordinator’s duty to protect the client’s interest, the public’s
interest and his/her employer’s interests, it shall be declared to the Client so that
arrangements can be made to resolve it.
In order to be PAS2035
compliant for monitoring and
evaluation, all projects must
have a Retrofit Evaluator
appointed. This includes both
the pre-assessment and post airtightness test.
PAS 2035 requires the delivery of engagement advice and improvement option
advice to be delivered by the Retrofit Assessor, with handover advice delivered by
the Installer (all under the oversight of the Retrofit Coordinator). The advice should
be provided to the dwelling occupants, regardless of tenure (i.e. the homeowner, the
resident or a landlord). Where the property is rented, it’s considered good practice
to ensure information is also provided to the tenant, especially in a social housing
setting; however, this is not covered in PAS 2035.
The full details of handover requirements are covered in section 12 of the standard (page 25).
The documentation required for the Client is the Assessment Report. This is what’s uploaded to
TrustMark as evidence of compliance, so it should also be offered to the Client by copy.
The Retrofit Assessor is
responsible for lodging
the Assessment Report.
The Retrofit Coordinator is
responsible for ensuring this
If an EPC is required for a property (e.g. as
requested by the client), then yes, one needs
to be lodged. However, an EPC is not a
requirement of the PAS unless sprecifically
requested by the client
As an example of an incomplete system, this could be where a home has extract
fans, but no trickle ventilators; or if there is only a fan in the kitchen OR the bathroom,
but not in both.
‘Not Functional’ would be where there are fans AND trickle vents present, but that
one or more element isn’t working. So, it might be that the fan has shorted out or
the trickle ventilators have been somehow disabled or blocked up. That would mean
there is a complete system in the home (with an intake and extract), but they’re not
working properly and may require like-for-like replacement or refurbishment.
The quality of your assessment
will be reflected in the quality of
your retrofit, so it is important
to make every effort to collect
the necessary information.
Where that is not possible,
make reasonable assumptions but include
a big contingency (e.g. of time and money)
for dealing with things that don’t turn out as
The appointment and payment for a Retrofit Assessor is not applicable to PAS
2035, and it will presumably vary project to project.
Yes, many Assessors work directly for the Installer. However, as they don’t
have the power to specify solutions, there should be no conflict of interest. The
Coordinator has to be the conscience of the project.
Covid restrictions are not
related to PAS 2035. It would
be down to the funding scheme
or client to determine what
A Retrofit Coordinator has
to register with one of the
Coordinator schemes. These
are currently Elmhurst, Stroma
CIGA (also known as IAA) and Retrofit Works
are also setting up schemes.
PAS 2035 states “The Retrofit Coordinator shall ensure that every dwelling that is
to be subjected to energy retrofit work is first assessed by a Retrofit Assessor, to
provide information about the dwelling for use by a Retrofit Designer (see Clause
However, one assessment report may be used to cover a group of similar properties,
provided that all dwelling-specific characteristics are identified
