£135m at Risk: Why Category 1 Hazards Should Be on Every Landlord’s Radar

Category 1 hazards in England’s private rented sector could trigger huge fines. New analysis shows why landlords need faster inspections, stronger records and clear evidence of action.

£135m at Risk: Why Category 1 Hazards Should Be on Every Landlord’s Radar
Share 6 min read

A serious property hazard is not just a maintenance problem. It can put tenants at risk, create a compliance headache and, under the latest rules, leave landlords facing a significant financial penalty.

New analysis from Property Inspect shows just how quickly that exposure could add up.

Based on the latest available inspection data, potential fines relating to Category 1 hazards across England's private rented sector could reach almost £135 million if the maximum £7,000 penalty were applied to one Category 1 hazard in every affected dwelling.

For landlords and property managers, the takeaway is simple: identifying serious hazards early, recording them properly and showing what has been done about them is becoming increasingly important.


What is a Category 1 hazard?

Category 1 hazards are the most serious hazards identified under the Housing Health and Safety Rating System (HHSRS).

They are issues considered to pose a significant risk to the health or safety of occupants. For property professionals, finding one is therefore more than another maintenance job to add to the list. It is something that requires clear action and a reliable record of what happens next.

Since June 2026, the maximum financial penalty applicable to each relevant hazard has been £7,000.

When you look at that figure across England's private rented sector, the potential scale becomes much clearer.

Almost 20,000 homes recorded with serious hazards

Property Inspect analysed the latest available government data, covering the year up to March 2025, on privately rented homes found to have at least one Category 1 hazard following an inspection.

Across England, 19,274 privately rented dwellings were recorded as having one or more Category 1 hazards.

If a maximum £7,000 penalty were applied to one Category 1 hazard in each of those properties, the potential total would be approximately £134.9 million.

This is an illustrative calculation rather than a forecast of fines that will actually be issued. But it demonstrates the level of financial exposure serious hazards can create when problems are allowed to go unidentified or unresolved.

Where is the potential exposure highest?

The figures vary significantly across England.

The North West recorded the largest number of affected properties, with 6,111 privately rented dwellings found to have one or more Category 1 hazards. At £7,000 per affected dwelling, that represents potential fines of approximately £42.8 million.

London follows with 3,863 affected dwellings, representing approximately £27 million, while Yorkshire and the Humber recorded 2,999 affected dwellings, equivalent to almost £21 million.

Elsewhere, the potential totals are:

  • South East: more than £10 million
  • South West: £8.1 million
  • East Midlands: £7.5 million
  • West Midlands: £7.3 million
  • East of England: £6.9 million
  • North East: £4.2 million

At local authority level, Blackpool stands out, with 3,768 privately rented dwellings recorded as having one or more Category 1 hazards. Based on the same calculation, that represents potential penalties of approximately £26.4 million.

Newham follows at £7.1 million, Leeds at £5.6 million, Brent at £4.2 million and Kingston upon Hull at £3.3 million.

The bigger issue is knowing what condition your properties are in

The headline figure is eye-catching, but there is a more practical lesson behind it. You cannot fix a serious hazard you do not know about.

For landlords, agents and property managers responsible for multiple properties, the challenge is not simply carrying out inspections. It is making sure there is a consistent process for recording what was found, deciding what needs attention, assigning the appropriate action and keeping evidence that the issue has been dealt with.

That becomes harder as portfolios grow.

Photos can end up in one place, inspection reports in another and maintenance updates somewhere else entirely. When someone needs to establish what happened at a particular property six months ago, piecing together that history can become unnecessarily difficult.

A stronger inspection process creates a clear journey from identification to action to evidence.

Good records matter just as much as good inspections

Spotting a problem is only the beginning. If a hazard is identified, property professionals need to be able to answer some straightforward questions:

What was found? When was it identified? How serious was it? Who was responsible for acting on it? What action was taken? And can you prove it?

This is where consistent digital inspection and reporting processes can make a real difference.

Instead of treating inspections as isolated reports, landlords and property managers can create an ongoing record of property condition, actions and outcomes.

As Sián Hemming-Metcalfe, Operations Director at Property Inspect, explains:

"Category 1 hazards represent serious risks within the private rented sector, and the financial consequences of failing to address them can now be significant.

For landlords and property managers, having a clear record of inspections, identifying issues early and being able to demonstrate that appropriate action has been taken are all important parts of effective property management."

From inspection to action

At Property Inspect, we believe inspections work best when they form part of a wider property management process. That means making it easier for teams to capture inspection information consistently, document property condition, keep photographic evidence and maintain a clear record of the actions required afterwards.

The goal is not simply to produce another report.

It is to give property professionals a clearer picture of what is happening across their portfolio, so issues can be identified earlier and the right action can be taken before a problem becomes more serious.

For teams managing hundreds or thousands of properties, that visibility can be particularly valuable. A consistent process can help reduce uncertainty, improve accountability and make it easier to demonstrate what has been done when questions arise later.

Prevention is easier than catching up

The potential £135 million figure demonstrates the scale of the issue across England's private rented sector, but the lesson for individual landlords and property managers is much simpler.

Know the condition of your properties. Record what you find. Prioritise serious issues. Keep track of the action taken.

A Category 1 hazard is serious enough on its own. Finding out too late that the evidence surrounding it is incomplete only makes the situation harder.

If improving your inspection and reporting process is not a priority today, it is worth remembering this when it is. Having the right systems in place before an issue arises is considerably easier than trying to reconstruct the evidence afterwards.

If you would like to see how Property Inspect can help you create clearer, more consistent inspection and reporting processes across your portfolio, we'd be happy to show you how it works.
