UK crematoria
Engineering the solution around the crematorium — not a fixed catalogue.
Available space, existing equipment, operating profile, energy supply, environmental requirements and investment strategy all influence the right technical solution. CFI Systems develops the architecture around the actual site and its objectives.
Hybrid cremators
A pragmatic route for sites seeking to reduce fossil-fuel dependence while retaining operational flexibility and the ability to adapt to changing energy strategies.
Electric cremators
Electric architectures can reduce direct fossil-fuel use and support lower-carbon cremation where the electrical infrastructure, operating profile and energy strategy make electrification appropriate.
Complete cremation system
From coffin to urn. From cremator to stack.
Real performance depends on the interfaces between equipment. CFI Systems therefore considers the operational cremation path and the flue-gas and energy path as one integrated process.
Automatic coffin charging
Motorised transfer, controlled insertion, charge-door coordination, position monitoring and safety interlocks adapted to crematorium procedures.
Cremator & control
Thermal cycle, combustion or electric heating, secondary combustion, air, energy, draft and automation coordinated throughout the cremation cycle.
Cremated-remains processing
Recovery, cooling, metal separation, cremulation, dust control and final preparation for placement in the urn.
Abatement & filtration
Cooling, reagent injection, pollutant capture, particulate filtration, extraction, instrumentation and controlled discharge.
UK CREMATORIA • PG5/2(25)
PG5/2(25) — preparing UK crematoria for 2029 compliance.
The current UK Process Guidance Note PG5/2(25) sets out the technical framework for crematoria, including emission limits, monitoring requirements, control measures and Best Available Techniques (BAT).
Under the current guidance, from 4 December 2029 existing cremators must comply with the emission limit values for new cremators. Replacement cremators are expected to meet the standards for new crematoria, while substantial changes — such as replacing the main cremation unit or retrofitting flue-gas treatment — can also trigger application of the current standards to the changed parts of the installation.
CFI Systems can support crematorium operators with the technical assessment and engineering work needed to evaluate upgrade, retrofit, abatement or replacement options. Regulatory interpretation, permit conditions and final compliance remain subject to the relevant UK regulator and the applicable permit.
Emission limits: assess the existing cremator against the values applicable from 4 December 2029.
Flue-gas treatment: evaluate abatement, filtration, reagent handling and mercury-control architecture.
Monitoring & controls: review instrumentation, process control, alarms, data and operating interfaces.
Retrofit: identify what can be retained, upgraded or replaced within the existing installation.
Replacement: define a new cremator and associated systems around current UK requirements.
Project phasing: plan works, temporary operating arrangements and commissioning around site constraints.
Flue-gas treatment & mercury abatement
PG5/2(25) also strengthens the importance of abatement planning.
The guidance applies to existing gas-fired and electric-fired cremators, with or without flue-gas treatment. It states that, unless an exemption applies, all cremators are to be fitted with flue-gas treatment including mercury abatement within four years of publication; unabated operation is otherwise restricted under the guidance.
For an existing crematorium, this makes the decision broader than the cremator alone. Space, ductwork, cooling, reagent injection, filtration, extraction, electrical infrastructure, controls and the interaction with the existing cremation process all need to be considered together.
Retrofit or replace?
Upgrade existing cremation equipment when complete replacement is not necessary.
An assessment of the existing installation can identify which components should be retained, modernised or replaced. The objective is to improve reliability, operability, energy efficiency and flue-gas performance while making the best use of equipment that remains technically relevant.
Automation
PLC, HMI, instrumentation, diagnostics, alarms and process supervision.
Combustion & energy
Burners, electric heating, combustion air, energy input and regulation.
Air & draft
Air circuits, extraction, negative-pressure control and interaction with filtration.
Flue-gas treatment
Cooling, reagent systems, filtration, extraction and associated auxiliaries.
Flue-gas treatment & abatement
The abatement system engineered together with the cremator.
CFI Systems treats the cremator and downstream flue-gas system as one process. Temperatures, pressure losses, extraction and treatment stages must remain coherent to protect overall plant performance and operability.
Cooling
Flue-gas temperature management suited to the downstream abatement equipment.
Abatement
Reagent injection, activated-carbon strategies and pollutant treatment according to the selected architecture.
Filtration
Particulate and treatment-residue removal with monitoring for reliable operation.
Extraction
Draft management, instrumentation and interaction between cremator, filtration and stack.
Heat recovery
Turn part of the available waste heat into useful energy.
Where the operating profile and local demand make recovery practical, thermal energy from cremator flue gases can contribute to building heating, hot water, district or local heat networks and other suitable thermal demands.
Building heating
Use recovered energy for crematorium or adjacent-building heating where the demand profile is suitable.
Hot water
Recover thermal energy for domestic or process hot-water production.
Heat networks
Study connection to district or local heat networks where infrastructure and demand exist.
Integrated design
Consider recovery from the design stage without compromising cremation or flue-gas treatment requirements.
Engineering experience behind a new company
Nearly 20 years of technical experience brought into a new, agile engineering structure.
CFI Systems was established in France in 2026 with a clear objective: to bring extensive industrial experience into a company dedicated to cremation, filtration and thermal-process technologies.
The company builds on nearly two decades of technical experience in cremation equipment, combustion systems, flue-gas treatment and industrial thermal installations. CFI Systems is based in Gien, France, and develops projects in France, the United Kingdom and international markets.
One engineering partner
Cremator → combustion → automation → flue-gas treatment → heat recovery.
A cremation installation combines several technical disciplines. CFI Systems brings them together within a single engineering approach, from an individual upgrade to a complete cremation system.
Frequently asked questions
Cremators and complete cremation systems for the UK.
Final technical characteristics are established project by project according to the site, operating profile, energy strategy and applicable requirements.
What is PG5/2(25)?
PG5/2(25) is the current UK statutory process guidance for crematoria. It covers matters including emission limits, monitoring, control measures and Best Available Techniques. The relevant regulator and permit remain authoritative for each site.
What changes on 4 December 2029?
Under the current guidance, existing cremators must comply from that date with the emission limit values applicable to new cremators. This can drive projects involving optimisation, abatement, retrofit or replacement.
Does CFI Systems design and manufacture cremators?
Yes. CFI Systems designs, develops, manufactures and integrates cremation equipment for new crematoria, replacement projects and modernisation of existing installations.
Can gas, hybrid and electric cremators be considered?
Yes. The energy architecture is selected around the site, electrical infrastructure, operating profile, objectives and long-term energy strategy.
Can CFI Systems upgrade an existing UK crematorium?
Yes. CFI Systems can assess existing cremators and associated equipment and develop retrofit, filtration, automation, energy or replacement scenarios.
Can CFI Systems provide flue-gas filtration and abatement?
Yes. Cooling, treatment, filtration, extraction and instrumentation can be engineered with the cremator as one coherent process.
