All 21 hazard profiles
The consolidated 2026 hazard set — damp & mould, excess cold, fire, falls and the rest of the four groups.
HHSRS Scoring
Put a statutory score behind the damp you found.
Damp and mould growth is an HHSRS hazard. DampApp Pro computes HHSRS scores from the likelihood and harm-outcome judgements entered by the surveyor, for all 21 hazard profiles of the 2026-amended system, tied to room-level evidence and rendered straight into the report. The score supports the assessment; it does not decide legal duties or replace professional judgement.
From observation to Category determination
Pick the hazard profile, enter your likelihood on the statutory 16-point scale and the spread of harm across the Extreme, Severe, Serious and Moderate outcome classes, and the app applies the published class weightings to produce the hazard score, the Low/Medium/High band and the Category 1/2 determination — the same arithmetic in the Operating Guidance, as amended in 2026. Link the rooms where the hazard presents so the score sits beside the moisture readings and photographs that support it. Apply Awaab’s Law and other legal duties using the current official guidance, not the score alone. Your judgements stay yours: the app never suggests a likelihood or a spread.
Statutory scoring
The 16-point likelihood scale, Extreme/Severe/Serious/Moderate spreads and the published formula — Category 1 at a score of 1,000.
Built for damp casework
Quick-add damp & mould, link the affected rooms, and keep the evidence beside the report. Use the current official guidance to decide any Awaab’s Law response.
Score only what matters
Add the hazards you judge worse than average — typically a handful per dwelling, not all 21.
Colour-coded reporting
Score, band and Category 1/2 pills in the report preview and PDF, with a statutory method note.
Region-aware
On by default for UK profiles; hidden elsewhere with a Settings toggle for anyone using the methodology as a reference.
Frequently asked questions
Which damp survey app calculates HHSRS hazard scores?
DampApp Pro. Enter your likelihood judgement on the statutory 16-point "1 in N" scale and the spread of harm across the four outcome classes, and the app computes the hazard score with the published HHSRS formula, assigns the Low/Medium/High band and determines Category 1 or Category 2.
Is it up to date with the 2026 HHSRS changes?
Yes. The module implements the framework as amended by the HHSRS (England) (Amendment) Regulations 2026, in force from 23 June 2026: the consolidated 21 hazard profiles, the Extreme/Severe/Serious/Moderate classes of harm and the simplified Low/Medium/High bands, with the Category 1 threshold unchanged at a score of 1,000.
How does this connect to Awaab’s Law?
Damp and mould growth is an HHSRS hazard profile, but Awaab’s Law Phase 1 uses its own “significant risk of harm” test and fixed timeframes for the social rented sector in England. An HHSRS score can inform a surveyor’s evidence; it does not by itself determine whether the Awaab’s Law duties apply. Record the affected rooms and use the current official guidance for triage and response.
Does it replace the assessor’s judgement?
No. The likelihood and harm-outcome judgements are yours, made for the occupier most vulnerable to each hazard per the Operating Guidance; the app computes the published arithmetic, presents the result and records the evidence. Enforcement decisions remain with the local authority under the Housing Act 2004.
Do I have to score every hazard?
No — as in practice, you add and score only the hazards you judge to be present and significantly worse than average, typically a handful per dwelling. Quick-add buttons cover damp and mould, excess cold, fire and falls.
Can it be used outside the UK?
HHSRS is England & Wales statutory methodology, so the section is on by default for UK profiles and hidden elsewhere — any region can enable it in Settings to use the methodology as a reference.
