Top 5 Climate Risk Software for Multi-Site UK Businesses in 2026

Climate risk software models how flooding, heat and wind will affect specific buildings and what that damage is likely to cost. For a single site, the main question is whether the tool covers the right hazards.

Across an estate of 100 or 1,000 UK properties, three further things decide whether it is any use:

1. site-level resolution rather than a regional average,

2. alerts that reach the manager who can act on them, and

3. pricing that holds as the estate grows.

This guide reviews five platforms against those criteria.

What should you look for across a large UK estate?

If you're responsible for climate risk across a portfolio of UK properties - not just one building - the tools that work for a single site often fall apart at scale. A single-site tool only has to answer one question: does it cover the right hazards? Managing 100 or 1,000 sites raises five more:

• Site-level resolution, not postcode averaging. A postcode-level score rarely tells you whether a specific warehouse or store sits in a flood plain, because two sites on the same street can sit a metre apart in elevation.

• Alerts that reach a named person, not an inbox. Site teams rarely act on a warning that lands in a shared distribution list, because nobody owns it.

• Evidence an insurer can use. Underwriters give more weight to site-level exposure data and a documented monitoring history than to a generic risk narrative.

• Screening that works before a site joins the estate. Multi-site operators grow through acquisition as often as new build, and a platform that only assesses sites already owned leaves that moment uncovered.

• Pricing that behaves predictably at scale. A quote built around a small pilot can shift once it covers a much larger estate, so it is worth understanding the model before signing anything.

The insurance criterion is not theoretical. UK insurers paid out £6.1bn in property claims in 2025, the highest annual total on record according to the Association of British Insurers (ABI), with £1.2bn of that weather-related, up 14% year on year. That figure spans domestic, commercial and business interruption policies, so it reflects the same property risk a multi-site commercial operator is priced against, not a home-insurance statistic that happens to mention weather.

The government's own flood warning service, run through the Environment Agency, illustrates the first two points well. It issues alerts for flooding from rivers, the sea or groundwater using a three-tier system, but it states plainly that it does not cover surface water flooding, also known as flash flooding, which is exactly the hazard that catches many commercial sites without warning. A platform built for estate-scale operators needs to close that gap, not repeat it.

What are the best climate risk software platforms for multi-site UK operators?

The best climate risk software platforms for multi-site UK operators are SmartResilience, XDI, S&P Global Climanomics, Risilience and Groundsure ClimateIndex, each strongest on a different one of the five criteria above.

1. SmartResilience

Best for: multi-site retail, hospitality, logistics and property portfolios in the UK.

SmartResilience combines real-time, site-specific monitoring with insurance-ready reporting, so an estate's risk picture updates as conditions change and as the estate itself grows or shrinks through acquisition and disposal. Portfolio-wide visibility sits in one view rather than a spreadsheet updated site by site.

Key capabilities:

• Continuous monitoring: The platform monitors every site in the estate continuously rather than at a single point in time.

• Automated, site-specific alerts: Site managers, risk teams and leadership receive warnings before a weather event escalates.

• Insurance-ready reporting: A broker receives auditable, site-level evidence to bring into a renewal conversation.

Limitations: SmartResilience quotes per engagement rather than publishing rates, so a first conversation is needed to understand cost for a specific estate size.

Pricing: SmartResilience quotes per engagement and does not publish a rate card.

2. XDI (XDI Climate Risk Hub)

Best for: engineering-grade, asset-level hazard modelling across large portfolios.

The XDI Climate Risk Hub models nine climate hazards across four scenarios in five-year time steps out to 2100, at a spatial resolution as fine as five metres by five metres, with results traceable to the point of failure within an asset. It is built to screen anything from a single site to portfolios of tens of thousands of assets, and is used by financial institutions, governments and corporates for stress testing and due diligence.

Key capabilities:

• Granular, sub-asset level hazard modelling: The platform models nine hazard types down to the point of failure within an individual asset.

• Scenario analysis to 2100: Planners can test long-horizon adaptation and capital decisions across four scenarios.

• On-demand screening: The platform screens anything from a single asset to a very large portfolio.

Limitations: XDI describes no insurance-specific use case and no continuous, real-time alerting on its own site, so a team that needs day-to-day operational monitoring would pair this with something else.

Pricing: XDI does not publish rates and mentions off-the-shelf reports, application programming interface (API) access and bespoke engagements.

3. S&P Global Climanomics

Best for: Climanomics suits enterprises already working in S&P's disclosure and reporting ecosystem.

Climanomics models the financial impact of physical and transition risk across eight decades and four Intergovernmental Panel on Climate Change (IPCC) scenarios, using a library of more than 300 asset types and over 1,200 impact functions, with outputs aligned to major sustainability disclosure frameworks. Analysis runs at asset level and aggregates up to portfolio level.

Key capabilities:

• Financial impact modelling: The platform models financial impact across a very long time horizon and multiple emissions scenarios.

• Disclosure-ready outputs: Reporting teams can produce outputs aligned to major disclosure frameworks.

• Asset-to-portfolio aggregation: Analysts can aggregate site-level results upward, with API access for custom reporting.

Limitations: Climanomics is built around portfolio-level financial modelling and disclosure rather than day-to-day, site-level alerting, so a facilities team needing an operational dashboard would find it a weaker fit than a reporting or investor-relations team would.

Pricing: S&P Global lists Climanomics at £16,200 a licence with a free trial covering up to three assets, according to the UK Government Digital Marketplace G-Cloud framework.

4. Risilience

Best for: Risilience suits organisations that need physical, transition and nature risk assessed together.

Risilience's Riise platform models physical, transition and nature risk through a single digital twin, aimed at identifying decarbonisation opportunities alongside physical exposure. Named clients on its own site include Tesco, Lidl, Coca-Cola, Reckitt, Burberry, Barclays and Nestlé.

Key capabilities:

• Combined risk view: The platform assesses physical, transition and nature risk in one place.

• Financial quantification and business-unit analysis: Strategy teams can quantify exposure by business unit for board-level decisions.

• Board-level engagement model: The client base skews toward large organisations in food, retail and financial services.

Limitations: Risilience describes no site-level monitoring, real-time alerting, insurance-specific use case or property-management-system integration anywhere on its own site.

Pricing: Risilience does not publish rates.

5. Groundsure ClimateIndex

Best for: ClimateIndex suits screening an individual UK property before you acquire it.

ClimateIndex is a property-specific report covering flooding, subsidence and coastal erosion, modelled against the UK Climate Projections 2018 (UKCP18) dataset over 5 and 30-year horizons. Commercial reports add energy performance and Minimum Energy Efficiency Standards detail relevant to a property transaction.

Key capabilities:

• Transaction-level due diligence: The report covers a single property at the point of purchase rather than a portfolio over time.

• UKCP18-modelled projections: The report projects flooding, subsidence and coastal erosion over 5 and 30-year horizons.

• Established transaction volume: Groundsure states that its reports have been used in over 1.3 million property transactions.

Limitations: ClimateIndex is generated once at the point of a transaction rather than run as an ongoing monitoring platform, so it pairs with an estate-wide tool for what happens after a site joins the portfolio.

Pricing: Groundsure prices residential reports from £87.35 to £131.05 plus value added tax (VAT) and commercial reports from £310 to £425.60 plus VAT, bundled within environmental due-diligence packages.

How do you decide between them?

Choosing a climate risk platform for a large estate comes down to which of five questions matters most to your business. No single platform above is strongest on all five. Ask directly:

• Does it resolve risk to an individual site, not a postcode or portfolio average?

• Do alerts reach a named person who can act, not a shared inbox?

• Does it produce evidence an insurer will actually use in a renewal conversation?

• Can it screen a prospective site before acquisition, not just monitor sites already owned?

• How does pricing behave as sites are added or removed and is that behaviour confirmed in writing before signing?

Practical tip: Ask each vendor to confirm pricing behaviour in writing for your full estate size rather than the pilot, before the first demo. Only two of the five platforms here publish a price at all, so most conversations will start from a private quote rather than a public rate card.

How SmartResilience helps you manage climate risk across a multi-site UK estate

Most teams reach the same point after a first assessment: they hold a hazard rating for every site and nothing a broker or a finance director will act on. Closing that gap is what SmartResilience does alongside your team:

• A financial figure for every site: The platform quantifies expected loss at site level using one methodology across the whole estate, so your team can put a number in front of finance rather than a description.

• Alerts routed to the people who can act: The platform issues site-specific early warnings to named site managers and risk leads before a weather event reaches the asset.

• Evidence built for a renewal conversation: Your broker receives site-level exposure data and a documented monitoring history, both traceable to the methodology that produced them.

• Adaptation measures ranked by return: The platform ranks measures by payback period, so your team can defend an adaptation budget on the terms finance already uses for capital decisions.

Sainsbury's partners with SmartResilience on early warning across 1,000+ sites and avoided a £3m flood damage event.

An estate that keeps growing and changing shape needs a risk picture built to keep up with it, not a report that describes it as it stood at the last annual review.

FAQs

What should multi-site UK operators look for in climate risk software?

Look for site-level resolution rather than a regional average, alerts that reach a named person, evidence an insurer can use, screening that works at acquisition and pricing that behaves predictably as the estate grows or shrinks.

Can climate risk software screen a site before you acquire it?

Some platforms do, including transaction-specific reports such as Groundsure ClimateIndex. Building this into the acquisition process itself, rather than after completion, closes a gap most buyers have not yet addressed.

Does SECR reporting change what I need from a climate risk platform?

Not directly. Streamlined Energy and Carbon Reporting (SECR) requires roughly 11,900 UK quoted and large unquoted companies to report their energy use and carbon emissions. It is an energy and carbon reporting framework, separate from the physical climate risk this guide covers.

Do smaller multi-site operators need the same software as a 1,000-site estate?

The underlying criteria are the same: site-level data, alerts that reach the right person and pricing that scales predictably. A smaller estate can usually start with a narrower rollout and expand as sites are added.

How much does climate risk software cost for a UK estate?

Pricing is rarely public. Of the platforms in this guide, only S&P Global Climanomics at £16,200 a licence and Groundsure ClimateIndex from £310 per commercial report publish a figure. The rest quote per engagement.
