Climate Resilience – How can commercial landlords prepare?

The impact of climate change on the world is ever more visible for us all to see - from the UK’s Storm Éowyn and the devastating wildfires in the US, to the latest floods in Gran Canaria.

The impact of climate change on the world is ever more visible for us all to see – from the UK’s Storm Éowyn and the devastating wildfires in the US, to the latest floods in Gran Canaria.

Global temperatures continue to rise, the number of extreme weather events are going up, and so too is the expected number of extreme rainfall days.  The latest prediction is that London could end up colder and wetter because of climate change, and changes to the Jetstream.

According to the Environment Agency, 2.4 million properties are at risk from rivers and the sea in England, 200,000 of which are in the South East alone.

High impact weather events like extreme temperatures or rainfall cause significant disruption and can affect everything from health, transport, agriculture and energy to commercial property.

In 2014 and 2023 Staines and Hastings were badly affected by severe flooding when several offices and the Priory Meadow Shopping Centre flooded in the towns, causing costly damage for the occupiers and landlords alike.

Faced with ever more extreme weather events such as flooding and heatwaves, what should landlords and investors of commercial property do to manage climate risk as best they can?

David Thomas, Head of Energy & Sustainability at Vail Williams, explores a range of practical steps and advice to build climate resilience and risk management into your commercial property management.

Pre-acquisition due diligence – Risk Assessment

Consider pulling together a climate change risk register allowing you to assess the legal, financial and commercial impacts of climate change on your business, providing for your commercial premises or property assets.

As part of this, and before investing in commercial premises, it is important to do your homework and make sure that the asset you are buying does not bring with it too much risk – be it from flooding, fire or otherwise.

Make sure that you get the usual risk assessments done to explore and map potential flood and / or fire risk areas through the necessary organisations such as the Environment Agency.

Remember, the risk from wildfires isn’t limited to rural areas. In 2011, the Transport Research Laboratory and Broadmoor High Security Hospital were both at risk from a wildfire which spread through seven hectares of land near Bracknell.

Practical resilience planning

If you already own a property asset that lies within an existing flood risk area, think about what you can do to mitigate potential damage within your building.

Flood risk mitigation

This can be about simple measures such as ensure that drains and gutters are maintained and kept unblocked to protecting the building from backflow of water.

In addition to surface water flooding and ensuring that heavy rainfall can escape away from the building, consider installing check valves to prevent floodwater backing up into your premises.

You can also benefit from use of parametric insurance, which uses a data-led approach to help protect organisations from catastrophic flooding.

For additional advice and support regarding flood risk mitigation strategies, this helpful blog from Macbeth Insurers Brokers provides important insights.

Snow / Ice

Make sure that there is a gritting policy in place for your premises, working with your local authority if required, to ensure that areas around your building are maintained with regular gritting.

Fire / Wildfire Risk

Ensure that your Fire Risk Assessment takes account of surrounding areas and not just your own premises.

Increasingly, insurers are asking that EV charging facilities, for example, are not located within seven metres of a building, or else the insurance will be invalid. With more and more EV charging facilities being installed close to commercial premises, it is important to consider the potential fire risk and how it could impact your property.

What if my asset is affected by an extreme weather event?

In the first instance, it is important to check that your tenant(s) and their employees are safe. Once you’ve established this, contact your insurance company.

In order to receive the necessary payout, you may need to demonstrate how you have lessened the potential impact of climate risk on the asset in question.

Stuart Adamson, Claims Manager at Macbeth Insurance Brokers based in the Thames Valley, advises:

“During severe weather events, insurers typically expect policyholders to take reasonable steps to prevent further property damage, known as mitigation. It’s important to maintain your property well, such as inspecting flat roofs for any issues and ensuring roof tiles are intact and undamaged.

“As a general rule, property owners are responsible for building insurance. However, rental agreements may assign repair responsibilities to tenants, so it’s advisable to review rental and lease agreements to confirm obligations.”

You should also think about contacting a business rates expert because if commercial premises are flooded causing damage, you may also be entitled to relief from business rates as a result of a material change in circumstances.

Who pays for the damage?

Most business leases include an obligation on the landlord to insure the property and most landlord insurance policies will cover storm damage.

However, if the property has not been well maintained, you could find that your insurer refuses to pay because you have not met with the obligations of the insurance policy.

“If an insurer’s inspection confirms that the property is well-maintained and a severe weather event has been acknowledged, the likelihood of a claim being accepted increases. A piece of advice I was once given, which holds true, is: Take care of your property, and your insurer will take care of you – provided policy conditions are met.”

Stuart Adamson, Claims Manager at Macbeth Insurance Brokers.
Putting in place a planned preventative maintenance (PPM) programme can help you to ensure this, whilst also providing documented proof for your insurance company, that you have proactively maintained your asset.

Who is responsible for repairs following a storm or other extreme weather event?

Commercial leases and repairing obligations can be a complex area of the law and are often the source of many a legal dispute.

The best thing that you can do as a landlord of commercial premises, is ensure that you have sought the input of a lease advisory expert and / or property lawyer.

They will ensure that the right lease terms are built into your contract with your tenant, so that should the need arise, there is clarity around repairing obligations.

It would not surprise us if there were additional ‘green lease’ clauses introduced by landlords for tenants to be alive to the potential issues caused by climate risk, to ensure they know how they need to protect the premises.

Building more climate resilience into the management of commercial property is a must – not just as we watch for the arrival of the next major weather event, but as look towards a turbulent future as global warming takes hold.
