RETROFIT ASSESSMENT / COORDINATION / EPC / AIR TESTING / NON-DOMESTIC
PAS 2035:2023 - CARRIED END TO END
Retrofit fails in the gaps between suppliers. We close them.
One accountable partner across the whole PAS 2035 journey - assessment, coordination and design, EPCs, air permeability testing and lodgement, carried by one team from first survey to final evaluation.
Programmes do not fail inside a trade.
They fail at the joins.
We close them.
"Unclear and fragmented roles, responsibilities and accountabilities." NATIONAL AUDIT OFFICE - ON WHY RETROFIT PROGRAMMES FAIL
The assessor who never speaks to the designer. The coordinator brought in after the handoffs have already happened. Evidence that lives in five inboxes and no audit trail. Vystra exists to be the one party that answers for the whole journey - so the gaps where funding, evidence and residents fall through simply are not there.
Compliance you can evidence
PAS 2035:2023 carried end to end. Every project lodged to the TrustMark Data Warehouse, with documentation built for the auditor from day one - the anti-clawback pillar.
One team, every stage
Assessment, coordination and design, EPCs, air testing and non-domestic assessment under one firm. No handoffs, one accountable contact, defined reporting to funders.
Programmes that keep moving
Realistic sequencing against the 31 March 2028 spend wall, dependable site coordination, and defects rectified fast when they surface.
Six stations. One bird.
One evidence trail.
Assess the whole house
Site survey, condition report and occupancy assessment by an accredited Retrofit Assessor - the evidence base everything else is built on.
EVIDENCE → SITE SURVEY / CONDITION REPORT / OCCUPANCY ASSESSMENTDesign against the assessment
Medium-term improvement plan, intended outcomes and ventilation strategy - specified for the property in front of us, reviewed at every later stage.
EVIDENCE → MTIP / IOEs / VENTILATION DESIGNOne name holds the thread
A TrustMark-registered Retrofit Coordinator owns the risk register, the sequencing and the reporting - the role the NAO says is missing when programmes fail.
EVIDENCE → RISK REGISTER / SEQUENCE PLAN / FUNDER REPORTINGWorks checked while they are live
Site visits and photo evidence captured against the design as installation happens - deviations surface while they can still be fixed cheaply.
EVIDENCE → SITE VISITS / PHOTO RECORD / DEFECT LOGVerify the fabric
Air permeability testing and post-works EPCs that prove the designed performance was delivered - not assumed.
EVIDENCE → AIR PERMEABILITY CERTIFICATE / POST-WORKS EPCClose the record
First-time lodgement to the TrustMark Data Warehouse and post-occupancy evaluation - the certificate your funding is drawn against, filed correctly.
EVIDENCE → TRUSTMARK CERTIFICATE OF LODGEMENT / POST-OCCUPANCY EVALUATIONWave 3 delivery, without the clawback letter
Warm Homes: Social Housing Fund Wave 3 is £1.29bn with every grant pound spent by 31 March 2028. We sequence realistically, lodge first time, and keep your evidence audit-ready - because clawback is a paperwork failure before it is a works failure.
Book a scoping call for your Wave 3 programmeYou hold the works contract. We make it fundable.
Coordination, assessment, testing and lodgement bought in as one accountable package beside your site teams - so compliance never sits between five subcontracts.

EPCs, MEES exposure and air testing handled properly - for lettings, sales and funded works alike.
Ask about your propertiesEverything a tender needs to find - written where a person can read it.
Vystra delivers whole-house retrofit under PAS 2035:2023, with installation interfaces managed against PAS 2030. Our TrustMark-registered Retrofit Coordinators and accredited Retrofit Assessors are named people on your programme, not logos in a footer.
First-time lodgement to the TrustMark Data Warehouse is our working standard - the Certificate of Lodgement your funding is drawn against, produced by the same team that created the evidence behind it.
Every programme hands over an audit-ready pack: survey and condition records, MTIP and intended outcomes, coordination risk register, in-works photo evidence, air permeability certificates, pre- and post-works EPCs and lodgement records - assembled as the work happens, not reconstructed after.
We carry professional indemnity insurance, work fluently across ECO4, GBIS, Warm Homes: Social Housing Fund, HUG2 and LA Flex, and design our reporting for the audits those schemes attract. We track the regulatory ground your board answers to - Awaab's Law, MEES - and write it into the plan.
