NTSELAT Material Information Parts A, B, and C: what UK letting agents must disclose in listings

Question

Accepted Answer

NTSELAT Material Information is the UK property-listing disclosure framework operated by the National Trading Standards Estate & Letting Agency Team. It sits inside the Consumer Protection from Unfair Trading Regulations 2008 (CPRs), which require traders to disclose material information that affects a consumer's transactional decision. NTSELAT translated the CPR requirement into a 3-part definition of what counts as material in UK property listings, published in stages: Part A in 2022, Parts B and C in 2023. All three parts now apply to every UK property listing on a property portal or marketing site.

## What 'material information' means under CPR 2008

The CPRs (UK statutory instrument 2008 No. 1277) make it a civil offence for a trader to omit, hide, or provide material information in a misleading way when marketing a product or service to a consumer. Property listings are explicitly in scope. Material information is defined as the information an average consumer needs to make an informed transactional decision (renting or buying). The CPR offence is strict-liability for omissions; intent is not required.

NTSELAT's job is to operationalise the abstract CPR concept of 'material' for the property sector specifically. The 3-part framework lists exactly what counts.

## Part A (in force since 2022)

Part A is the bedrock: identity, tenure type, council tax band, price/rent. The 5 Part A fields:

1. **Asking price or rent**. The headline number, in pounds.
2. **Tenure**. Freehold, leasehold (with years remaining), share of freehold, commonhold, or for lettings: assured shorthold tenancy (pre-RRA-2025) or periodic tenancy (post-RRA-2025).
3. **Council tax band**. Bands A through H (or I in Wales).
4. **Property type**. Detached, semi-detached, terraced, flat, maisonette, bungalow, etc.
5. **Number of bedrooms**.

Missing or wrong Part A fields trigger Trading Standards exposure and portal-listing rejection.

## Part B (in force since 2023)

Part B adds tenure detail and the most-relevant additional disclosure fields. The 8 Part B fields:

1. **Lease length** (for leasehold property: years remaining on the lease).
2. **Annual ground rent + escalation terms** (leasehold).
3. **Annual service charge** (leasehold).
4. **Council tax / business rates band** (already in Part A; Part B fleshes out the detail).
5. **Property construction type** (timber frame, modern methods of construction, non-standard).
6. **Heating type and energy supply**.
7. **Parking arrangements** (allocated, on-street, garage, none).
8. **Restrictions and rights** (restrictive covenants, public rights of way, easements affecting the property).
9. **Building safety** (relevant for leasehold flats post-Grenfell: EWS1 form status, cladding system, building safety risks).
10. **Flooding history** (whether the property has flooded in the last 5 years, irrespective of current Environment Agency band).

Part B is the disclosure layer that most affects buyer / tenant decisions; missing it tends to trigger consumer complaints to local Trading Standards rather than portal rejections.

## Part C (in force since 2023)

Part C covers location-specific risk and accessibility factors that materially affect a transactional decision. The 8 Part C fields:

1. **Flood risk** (Environment Agency flood band: river, sea, surface water). Part B covers historic flooding; Part C covers current risk band.
2. **Coastal erosion risk** (where applicable).
3. **Mining heritage** (coal authority data; non-coal mining heritage where applicable).
4. **Subsidence and ground conditions** (clay shrinkage zones, etc).
5. **Planning permission and proposals** (existing planning approvals; live planning applications in the immediate vicinity).
6. **Listed status and conservation area** (where applicable).
7. **Accessibility features** (step-free access, lift access, internal mobility features).
8. **Property-specific environmental hazards** (radon zone, contaminated-land register hit, landfill proximity, knotweed proxy, etc).

Part C is the layer that letting + estate agents most often miss because it requires data sources outside the firm's standard property-marketing toolkit. The flood + mining + contaminated-land sources are all free and authoritative, but they're scattered across multiple government and local-authority portals.

## How portals police NTSELAT

Rightmove, Zoopla, and OnTheMarket are increasingly policing Part A and B completeness automatically. Listings that don't include the Part A and B fields are rejected at upload or flagged for the agent to complete. Part C is harder for portals to police because the data is per-property and the portal can't always know whether a Part C field applies. The enforcement burden falls on agents to surface Part C correctly; consumers can report omissions to local Trading Standards.

In practice, the Part C enforcement is consumer-driven: a tenant who moves into a property and then discovers undisclosed flood history or a contaminated-land hit can complain to Trading Standards, who then investigates the agent's marketing material. NTSELAT-Part-C failure is a CPR 2008 unfair-trading offence carrying civil penalties.

## How CPR enforcement actually works

CPR 2008 has been the underlying authority since long before NTSELAT existed; enforcement runs through local Trading Standards Service offices (county-level or unitary-authority). Penalties for CPR breaches:

- **Unfair commercial practice (general)**: civil penalty up to £25,000 per infringement, or up to 4% of annual UK turnover for the agency, whichever is higher.
- **Misleading omission specifically**: same penalty scheme.
- **Repeat or persistent breach**: criminal prosecution available; unlimited fine on conviction.
- **Director liability**: individual directors can be personally liable where they consented to or connived in the breach.

In practice, Trading Standards prefers civil resolution: an undertaking from the agent to update the listing and improve disclosure procedures usually closes the file. Repeat or wilful breaches escalate to penalties.

## What letting + estate agents should do at marketing stage

The practical workflow for full NTSELAT-Part-A-B-C compliance:

1. **At instruction**: pull a full property-information form from the landlord or seller. Include Part B detail (lease length, ground rent, building safety, flooding history if known). Reject the instruction if the landlord refuses material disclosure.

2. **Pre-listing data pull**: fetch the EPC, MEES verdict, flood band, contaminated-land flag, coal-mining flag, radon zone, knotweed proxy for the property postcode. These are the Part C fields most often missed.

3. **Listing draft**: include all Part A + Part B fields in the marketing material. Surface relevant Part C flags inline with the listing (don't bury them).

4. **Portal upload**: submit through Rightmove + Zoopla + OnTheMarket with all required fields populated; the portal's automatic completeness check catches Part A and B gaps.

5. **Tenant or buyer enquiry response**: when a prospective tenant or buyer asks about a Part C field (flood, mining, contaminated land), provide the data directly from the pre-listing pack. Don't say 'I don't know' on a CPR-material field.

## How Certaby helps with NTSELAT compliance

The property pack capability (postcode-intelligence + EPC + Companies House) covers all the Part C location-specific risk data in one call. Specifically:

1. **Flood** (EA river + sea + surface water bands): Part C field 1.
2. **Coal mining heritage** (Coal Authority bulk data): Part C field 3.
3. **Contaminated-land register hits** (75+ UK local authority registers): Part C field 8.
4. **Radon zone** (UKHSA): Part C field 8.
5. **Knotweed proxy** (BSBI distribution): Part C field 8.
6. **EPC + MEES** (MHCLG live): tied to Part A property type and Part B heating + energy fields.

Run the full property pack standalone at £9.95 (`/pricing` Property Pack), bundled inside S1 letting-agent suite at £4.95, or in S2 conveyancer pack at £19.95. For multi-property portfolio audits ahead of relisting, the bulk CSV at /bulk runs the pack against every postcode in one batch at £4.50 per row.

What Certaby does NOT cover from NTSELAT: the property-specific data that lives only with the landlord (lease length, ground rent, service charge, building safety EWS1 status, historic-flooding admission). Those need to come from the landlord at instruction; we can't infer them from postcode alone. Pair Certaby's location-side property pack with a thorough at-instruction property-information form to cover Parts A + B + C completely.
