Sustainability, Carbon Reduction & Insurance in Brick Production

Introduction

Brickmaking is one of the most established parts of UK construction supply, but it sits under growing pressure to cut emissions, prove responsible sourcing, and keep production resilient. For brick manufacturers, sustainability is no longer just a marketing line. It affects planning permissions, customer tenders, financing, energy costs, and—often overlooked—insurance.

Carbon reduction programmes can change your risk profile. New fuels, new plant, new suppliers, and new processes can introduce unfamiliar hazards, contractual obligations, and business interruption exposures. The goal is to reduce emissions without creating uninsured gaps.

This guide explains where carbon is generated in brick production, common reduction strategies, and how to align your insurance programme with operational change.

Where carbon comes from in brick production

Brick production emissions typically fall into three buckets:

• Process emissions and heat demand: Firing bricks requires sustained high temperatures. The kiln fuel source (gas, electricity, biomass, hydrogen blends) is often the biggest driver.
• Electricity use: Fans, conveyors, grinding, extrusion, drying, and handling equipment can be electricity-intensive.
• Upstream and downstream impacts: Clay extraction, transport, packaging, and distribution contribute to the product’s overall footprint.

In practice, carbon reduction plans usually focus on kiln and dryer efficiency, fuel switching, and reducing waste and rejects.

Carbon reduction strategies (and what they change operationally)

No two sites are identical, but most programmes include a mix of the following.

1) Energy efficiency and process optimisation

Common measures include kiln insulation upgrades, heat recovery, better controls, and optimised firing curves.

Insurance angle: Efficiency upgrades can be positive, but they often involve hot works, shutdowns, commissioning periods, and changes to critical machinery. If you’re installing new burners, controls, or heat exchangers, you may need to review:

• Engineering inspection requirements
• Machinery breakdown cover limits
• Business interruption indemnity period (can you recover if commissioning overruns?)

2) Fuel switching and alternative fuels

Moving from natural gas to electricity, biomass, biogas, or hydrogen blends can reduce emissions, but it can also change fire, explosion, and supply chain risks.

Insurance angle: Fuel switching should trigger a structured review with your broker and insurers. Key questions include:

• Is the new fuel stored on site? If yes, what are the quantities and controls?
• Are there new ignition sources, dust risks, or explosion zones?
• Does your policy have exclusions or conditions relating to combustible dust, flammables, or process changes?

3) Electrification and renewable power

Electrifying parts of the process and purchasing renewable electricity (or installing on-site solar) can reduce Scope 2 emissions.

Insurance angle: On-site renewables introduce new property exposures (storm, theft, fire) and new liability considerations (maintenance contractors, roof loading, electrical safety). If you export power, contractual and grid-connection obligations may also matter.

4) Raw material and product innovation

Manufacturers may explore lower-carbon clay blends, additives, recycled content, or new product lines designed for improved thermal performance.

Insurance angle: Product changes can affect:

• Product liability exposures (performance claims, fitness for purpose)
• Recall costs (if defects are discovered after distribution)
• Professional indemnity exposures (if you provide design/specification advice)

5) Waste reduction and circularity

Reducing rejects, reusing offcuts, and improving packaging can cut both cost and carbon.

Insurance angle: Waste handling changes can alter fire load and storage risks. Stockpiles of combustible packaging or alternative fuels can increase fire severity.

Regulation, standards and customer expectations (UK context)

Brick producers are increasingly asked to demonstrate carbon performance and responsible operations. Depending on your site and customers, you may encounter:

• Environmental permits and local authority requirements
• Customer tender requirements around Environmental Product Declarations (EPDs), carbon reporting, and supply chain due diligence
• Construction product and building standards expectations (including performance and traceability)

Even when a requirement is contractual rather than statutory, failing to meet it can create financial loss, reputational damage, and disputes.

How sustainability initiatives affect your risk profile

Carbon reduction is a change programme. Change creates risk, especially when it involves plant, people, and process.

Construction and installation risk

Upgrades often require contractors, shutdowns, and temporary works.

• Hot works and ignition sources
• Lifting operations and machinery moves
• Testing and commissioning failures
• Delays that extend downtime

Supply chain and dependency risk

Alternative fuels and specialist parts may have fewer suppliers.

• Single-source dependency
• Longer lead times
• Price volatility
• Contractual penalties for late delivery

Operational and safety risk

New processes can introduce unfamiliar hazards.

• Hydrogen and gas safety management
• Combustible dust and explosion controls
• Electrical hazards from higher loads
• Training gaps during transition

Reputational and “green claims” risk

Sustainability statements can create exposure if they are challenged.

• Allegations of misleading environmental claims
• Customer disputes over stated carbon data
• Increased scrutiny after incidents

The insurance covers brick manufacturers should review

A carbon reduction plan is a good time to review the full programme, not just property.

Property damage and business interruption

Your property policy should reflect the true replacement cost of buildings, plant, and stock. Business interruption should reflect the time it would realistically take to rebuild or replace critical equipment.

Consider:

• Declared values for kilns, dryers, and controls
• Increased cost of working (temporary plant, outsourcing, expedited shipping)
• Indemnity period (many manufacturers need 18–24 months, sometimes longer)
• Utility interruption and denial of access extensions

Machinery breakdown / engineering insurance

Modernisation often increases reliance on control systems and specialist components.

Consider:

• Breakdown cover for critical plant
• Inspection regimes and compliance with policy conditions
• Cover for consequential loss (loss of profit following breakdown)

Contractors’ works / project insurance

If you are installing major upgrades, you may need project-specific cover.

Consider:

• Contract works / erection all risks
• Delay in start-up (DSU) cover for major projects
• Clear allocation of responsibilities between principal and contractors

Employers’ liability and public liability

Sustainability upgrades can change site activities and contractor management.

Consider:

• Contractor control and permit-to-work systems
• Traffic management and visitor safety
• Pollution liability exposures (see below)

Environmental impairment / pollution liability

Even with best practice, manufacturing sites can face pollution incidents.

Consider:

• Sudden and accidental pollution cover
• Gradual pollution extensions (where available)
• Clean-up costs, third-party claims, and regulatory investigation costs

Product liability and recall

If you introduce new blends or product lines, ensure your liability cover matches your output.

Consider:

• Fitness for purpose and performance allegations
• Contractual liability assumptions
• Recall costs and crisis management

Cyber insurance

Efficiency and carbon reduction often rely on automation, sensors, and connected systems.

Consider:

• Ransomware and operational disruption
• Business interruption from cyber events
• Supplier and IT service provider dependency

Directors’ and officers’ (D&O) liability

Where sustainability reporting and governance are in scope, D&O can be relevant.

Consider:

• Claims relating to disclosures, governance, and stakeholder actions
• Investigation costs and legal defence

Common insurance pitfalls during decarbonisation projects

A few issues regularly create gaps:

• Not telling insurers about material changes to process, fuels, storage, or production volumes
• Underinsuring upgraded plant (values not updated after capital spend)
• Inadequate business interruption indemnity period for specialist kiln components
• Relying on contractor insurance without checking limits, scope, and principal’s interest
• Assuming “green tech” is automatically covered under existing wordings

Practical steps: aligning carbon reduction with insurance

A simple approach that works well for many manufacturers:

1. Map the change: list each upgrade, what it replaces, and what new hazards it introduces.
2. Update valuations: rebuild costs, plant replacement, and stock values.
3. Review critical dependencies: utilities, single suppliers, and specialist contractors.
4. Check contract terms: warranties, performance guarantees, liquidated damages, and liability caps.
5. Engage early: involve your broker and insurers before installation and commissioning.
6. Document controls: risk assessments, training, maintenance plans, and emergency response.

Conclusion

Sustainability and carbon reduction in brick production is both a commercial opportunity and a risk management project. The manufacturers who win tenders and keep margins are often the ones who can prove performance, resilience, and governance.

Insurance should support that transition—protecting upgraded plant, covering downtime realistically, and responding to new exposures created by alternative fuels, automation, and product innovation.

Call to action

If you’re planning kiln upgrades, fuel switching, or new low‑carbon product lines, it’s worth reviewing your insurance before you commit. A broker who understands manufacturing risk can help you avoid uninsured gaps, update sums insured, and build a programme that matches your decarbonisation roadmap.
