Baseline-first retrofit: how to prove outcomes at scale in social housing
Wave 3 delivery has shifted the goalposts. Sustainability teams are now expected to deliver verified decarbonisation, EPC C uplift, fuel poverty impact, and improved indoor environmental quality — while staying inside strict spend profiles and operating under increased scrutiny from the Regulator of Social Housing and the Housing Ombudsman.
That combination creates one unavoidable reality:
Retrofit isn’t “install measures” anymore. It’s “prove outcomes”.
And the organisations that will move fastest (and defend results most confidently) are standardising a baseline-first approach.
The retrofit evidence gap nobody can fix later
Most programmes think about evidence at handover. But the most defensible evidence starts before the first measure is installed.
Wave 3 delivery windows are fixed — and if monitoring begins after the Retrofit Assessment, you’re already behind:
- your Retrofit Assessor has no pre-retrofit baseline to work from
- your funder has no M&V foundation to audit against
The most important line to remember:
Pre-retrofit baseline data cannot be recreated retrospectively.
Every week you delay is baseline data you can’t recover.
What “baseline-first” really means in Wave 3 terms
Baseline-first is a delivery discipline: you establish a pre-measure baseline, then use that baseline to generate a before/after evidence trail that your Retrofit Coordinator can sign off — and your funder can audit.
Vericon describes this as the Wave 3 Compliance Assurance Layer: Monitoring & Verification (M&V) infrastructure that proves “Least Regrets” measures work in the real world.
The approach integrates three proof streams into one evidence trail:
- Heating performance (BCM)
- Environmental quality (MultiDot)
- Electrical consumption (PowerSense)
The simplest way to think about “proof” at scale: 3 baselines
Heating baseline (carbon + EPC uplift proof)
Heating is the largest driver of housing emissions — and it’s also where “deemed savings” regularly fall apart in the real world. BCM provides visibility into heating performance and resident behaviour without needing property visits.
It’s positioned to deliver 10–18% verified reductions in heating-related gas consumption by optimising boiler flow temperatures (load compensation alignment), preventing dry-cycling, and identifying high-usage behaviours.
Just as importantly, it validates whether Wave 3-funded fabric measures are actually reducing demand post-install.
IEQ baseline (damp/mould risk + wellbeing evidence)
Healthy homes outcomes can’t be asserted — they need evidence.
MultiDot continuously monitors conditions that drive comfort, wellbeing, mould risk and fuel poverty indicators.
It’s positioned to provide early detection of damp and mould risk, and to verify ventilation performance following retrofit as part of the PAS 2035:2023 evaluation requirement.
The document also frames MultiDot outputs as ESG-ready and useful for Tenant Satisfaction Measures, Ombudsman defence (timestamped audit trail), retrofit evaluation reporting, and Awaab’s Law readiness.
Electrical baseline (heat pumps, PV, and CoP verification)
Decarbonisation requires proof. PowerSense monitors circuit-level electrical consumption to validate low-carbon heating and renewables performance.
It’s positioned to verify real-world heat pump CoP against MCS design specifications, plus PV/battery utilisation and baseline electricity consumption for planning and funding applications.
“But where does this sit in Wave 3 budgets?”
One of the strongest points in the document is how it reframes monitoring:
Instead of treating it as an operational add-on, Vericon positions POE/M&V as a capitalised project assurance tool that can be eligible within the Wave 3 “Administration & Ancillary” allocation (up to 15% of total project cost, per Scheme Guidance referenced in the doc).
It also provides indicative cost guidance for a “Sustainability pack” (BCM + 2 MultiDots + PowerSense + portal/reporting/data) at an average cost of £523.83 with 3 years’ data.
What to standardise (and what to leave “by exception”)
If you’re trying to prove outcomes across hundreds or thousands of homes, the win is not “collect more data”. The win is standardising the evidence method so it becomes repeatable and auditable:
- baseline starts before measures
- outputs map cleanly to the PAS 2035 delivery chain (RA at assessment/targeting, RC at evaluation/sign-off)
- evidence supports TrustMark / MCS workflows and compliance documentation
- data integrates into your asset/BI stack (data sovereignty, no silos)
The detailed “how” — what to baseline, how to structure evidence packs, and what your RC will actually receive — is exactly what the downloadable document is for.
Download the document: the full baseline-first evidence model (Wave 3)
If you’re mobilising a Wave 3 programme (or preparing a bid), you don’t need another retrofit overview. You need a clear evidence pathway that your funder and Retrofit Coordinator can stand behind.
Inside the PDF you’ll get:
- the Wave 3 Compliance Assurance Layer model (BCM + MultiDot + PowerSense)
- how to position M&V spend inside Admin & Ancillary headroom (15%)
- what outputs your Retrofit Coordinator receives, mapped to POE/Evaluation
- indicative pack contents and cost guidance
Optional next step: the doc also offers a free 30-minute Wave 3 Portfolio Scoping Session to map stock eligibility, model Admin & Ancillary headroom, and walk through live outputs (including joining a call with your Retrofit Coordinator).
MouldSense: The Smart Solution for Damp & Mould Management
Prevention and proof in one connected workflow.
Most organisations still tackle damp and mould with a patchwork of sensors, spreadsheets and site notes. It’s slow, inconsistent, and hard to evidence. MouldSense brings everything together—continuous environmental monitoring to spot risk early, guided actions to resolve issues quickly, and an audit-ready record that shows what happened, when, and why.
Why this matters now
- Risk is dynamic. Temperature and humidity can drift quickly, especially in older stock.
- Teams are stretched. Fragmented tools create duplicated effort and missed signals.
- Evidence is essential. Clear, time-stamped records reduce disputes, rework and repeat visits.
Bottom line: MouldSense turns signals into a repeatable, defensible process that asset, repairs and resident teams can follow together.
What MouldSense is
A connected workflow that unifies:
- Environmental monitoring (temperature, humidity) across homes
- Guided investigations with time-stamped notes and photographic evidence
- Works planning & validation against clear timelines
- Reporting & audit via Vericon Connect/Portal
- Resident communication through HomeHub
Result: earlier intervention, fewer callouts, and confident reporting.
How it works: the five-step loop
- Investigate
Live environmental data highlights properties drifting into risk so teams can prioritise interventions. - Summary
Create a clear case summary with evidence—conditions, likely causes, and recommended next steps. - Repairs
Plan and track works; validate completion with before/after data and photos. - Audit
Automatic timestamps and case histories provide an audit-ready record without extra admin. - Feedback
Close the loop with resident updates via HomeHub; continue monitoring to ensure improvements hold.
Outcome: a single source of truth across departments—no chasing spreadsheets.
What housing providers achieve with MouldSense
- See risk sooner. Trend and threshold alerts pinpoint properties moving into unsafe conditions.
- Act with clarity. Guided checklists, photos and notes keep cases moving.
- Prove improvement. Audit-ready logs show what changed, when—and that it stayed fixed.
- Reduce disruption. Fewer unplanned visits; faster, more targeted resolution for residents.
- Validate retrofit. Benchmark before works; confirm ventilation and heating performance after.
- Scale with confidence. Compatibility-first devices and a unified platform make portfolio roll-out straightforward.
Benefits for residents

The Clock is Ticking: Meeting Awaab’s Law Compliance in Time
In less than a month, Awaab’s Law comes into force. For social housing providers across the UK, this marks the start of a new legal duty to act swiftly on damp and mould, with strict timelines and expectations around evidence. The countdown is real, and the challenge is significant: compliance is no longer about good intentions — it is about demonstrable action.
What Awaab’s Law Demands
Awaab’s Law sets strict expectations for how landlords must deal with damp and mould hazards:
- 24 hours to act on emergency hazards.
- 10 working days to investigate potential significant hazards.
- 3 working days to share written findings with the tenant after an investigation.
- 5 working days to begin repairs if a significant hazard is confirmed.
- Up to 12 weeks to complete more complex works if immediate action isn’t possible.
- Provide alternative accommodation if safety works can’t be finished in time.
- Keep tenants updated throughout, with clear guidance on how to stay safe.
At its core, the law demands speed, accountability, and clear communication. Providers must not only resolve issues quickly but also prove every step — from first report to final repair.
Turning Compliance into Confidence
Vericon Systems exists to help landlords meet these requirements without overwhelming their teams. Our MouldSense package is designed specifically with Awaab’s Law in mind. It combines:
- MultiDOT sensors to measure temperature and humidity, supporting early detection and root-cause analysis.
- HomeHub to automatically log repairs, inspections, and resident communications with date and time stamps.
- Comprehensive data and reporting tools that validate pre- and post-retrofit works, giving providers a defensible evidence trail for regulators.
Together, these tools give housing providers a proactive, scalable way to manage damp and mould risks while building transparency and trust with residents.
Real Results from the Sector
Housing providers are already seeing the impact of this approach.
Chris Roberts, Sustainability Manager at Plus Dane Housing, explains:
“Although the Vericon system has only been live for a matter of months, we are already seeing positive results. With the ability to proactively monitor, manage, and evaluate humidity levels within our properties, we can prevent the build-up of damp and mould and all of the problems they bring. Vericon’s ongoing service and support has been first class.”
At Raven Housing Trust, Vericon’s technology is forming the backbone of a proof of concept designed to scale:
“The integration of the BCM, MultiDot, and Autofill technologies has empowered us to proactively monitor and manage damp and mould risks across our properties… This partnership not only supports the spirit of Awaab’s Law, but it also strengthens our commitment to delivering healthier, safer homes.”
Michael Ryan, Head of Property Services, Raven Housing Trust
And at Clarion Housing Group, proactive monitoring is already changing resident outcomes:
“The MultiDot sensors have been a pivotal tool for root cause analysis… We have been able to identify hotspots and proactively reach out to these residents to improve their quality of life before it can become a bigger problem. The monthly reporting from the Vericon team means we can confidently identify properties of higher risk and effectively manage these cases with more transparency, all the way through to completion.”
Ross Wiles ACMI fCMgr, National Lead LCDM, Clarion Housing Group
These are not isolated examples. They represent a wider shift in the sector — from reactive firefighting to proactive management — enabled by connected technology.
Why Act Now
With less than a month to go, the time for planning is running out. The penalties for non-compliance are serious, but the bigger risk is to residents’ health and wellbeing. Every delay, every missed inspection, and every undocumented repair creates exposure — for providers and for families.
The good news is that solutions exist today. Vericon’s MouldSense package is already in place across the UK, delivering measurable improvements in compliance, transparency, and resident trust. By acting now, housing providers can enter this new regulatory era with confidence rather than concern.
The Clock Is Ticking
Awaab’s Law is more than legislation. It is a call to the sector to ensure that tragedies like Awaab Ishak’s never happen again. Meeting its requirements is a legal duty, but also a moral one.

Awaab’s Law: New Updates Every Social Landlord Needs to Know
Awaab’s Law is moving from headline news to operational reality, with the government releasing updated draft guidance and the 2025 regulations that finally clarify what’s expected of social landlords. If you’re responsible for damp, mould, or hazard management in social housing, these changes are more than just administrative—they represent a fundamental shift in what “best practice” looks like.
Visit our Awaab’s Law Page here.
At Vericon, we know compliance isn’t just about ticking boxes. It’s about protecting residents, reputations, and budgets. Here’s how the latest updates affect you—and how we can help.
How Vericon Supports Landlords at Every Step
Real-Time Damp & Mould Detection:
Our analytics do more than simply flag a problem: they quantify risk and identify causality, ensuring you meet statutory requirements and put an end to recurring cases.
Automated Tracking Deadlines:
From day one, when the clock starts ticking, we create a full date- and time-stamped audit log, along with any photographic evidence captured during surveys. This validates compliance and can be included in your resident correspondence to demonstrate you are actively managing their issues.
Clear Resident Communication:
Simplify and validate your resident communication by including a date- and time-stamped audit log and any photographs captured during the process. Where HomeHub is fitted, this communication and future updates can be accessed via the in-property 7-inch screen.

Our Awaab’s Law landing page and BREATHE EASY guide break down the rules and provide practical, actionable steps for your team.
The 2025 Rule Changes
And How Vericon Keeps You Compliant
Inspections Within 10 Working Days
The Rule:
Inspect any reported or detected hazard within 10 working days.
The Risk:
Tighter timescales increase the risk of missed or late inspections and regulatory breaches.
How Vericon Helps:
Let us take control from day one. Our real-time damp and mould risk management uses causality analytics and photographic evidence to pinpoint the cause of risk—often before a resident needs to complain. Automated workflows schedule and track inspections the moment an alert is raised, ensuring you never miss a regulatory deadline. After your investigation, you’ll have the data and evidence to provide a clear summary of findings to the resident.
**By October 2025, you’ll need systems that can triage risk, schedule and track every inspection, and securely store evidence and notes from every visit.**
Repairs Must Begin Within 5 Working Days
The Rule:
Repairs must start within 5 working days of confirming a health-related hazard.
The Risk:
Shorter timescales make contractor coordination and documentation business-critical.
How Vericon Helps:
Our platform logs all confirmed hazards and instantly notifies your maintenance teams. Progress—including photo evidence and install updates—is tracked on a central dashboard, providing real-time validation of work completed. No more “slipped through the cracks”—your teams have instant access to the data they need to keep repairs on track.
**By October 2025, you’ll need systems that track repairs, store photographic evidence, and maintain a full repair history—ready for audit at any time.**
Written Summary to Resident Within 3 Working Days
The Rule:
After any inspection, you must provide a written summary to the resident within 3 working days.
The Risk:
Communication failures are now compliance failures.
How Vericon Helps:
Vericon captures and organises all inspection findings, next steps, and timescales in clear, exportable formats—so you can create your written summary with ease. All inspection content and findings are shared with the housing provider via a Vericon report and available on your online dashboard. This information can be shared with residents, ensuring they’re kept updated and know how to stay safe.
**By October 2025, you’ll need to generate plain-language resident reports within 48 hours and log all resident communications.**
Emergency Hazards—Action Within 24 Hours
The Rule:
Emergencies require attendance and action within 24 hours.
The Risk:
There is no margin for error—delays create immediate risk for residents and your organisation.
How Vericon Helps:
Our 24/7 monitoring flags emergencies in real time. Escalation protocols alert your response teams instantly, with incident logs, quantified risk ratings, and timestamps ready for audit or legal defence. Crucially, our causality analytics identify the root cause—helping you prevent repeat issues.
Complex Works—Start Within 12 Weeks
The Rule:
Where works can’t begin within 5 days due to structural complexity or access, they must commence within 12 weeks.
The Risk:
Ambiguity around “complex works” puts the onus on robust documentation and transparent processes.
How Vericon Helps:
From the moment complex work is identified, real-time monitoring provides pre- and post-works data—validating progress and completion. Every case is fully logged, with all communications, actions, and scheduled works stored securely in one place. This information can be shared with residents, ensuring they’re kept updated and know how to stay safe.
**By October 2025, you’ll need to store full case records—including evidence, communications, and follow-up—securely for at least six years.**
What the Experts Are Saying
Recent analysis from Clyde & Co highlights the impact: for the first time, the law sets enforceable timeframes for resolving hazards in social housing, with penalties for non-compliance. Residents can now bring claims for breach of these legal duties, and landlords will need to prove not only that hazards were addressed, but that every step—from investigation to communication—was done on time and by the book.
Are You Ready for October 2025?
- The new law is clear: by October, every landlord must have systems that can:
- Triage risk at first contact
- Automatically track inspections
- Store photo evidence, inspection notes, and full repair history
- Generate plain-language resident reports within 48 hours
- Log education and follow-up for unresolved or recurring cases
- Store all records securely, accessible for a minimum of 6 years
Our technology is built for the future—giving you the tools, data, and evidence to not only comply, but to lead on safety and resident engagement.
