What Causes Church Fires in the UK and How We Can Prevent Them

By Fletcher Risk | Chester · Liverpool · Manchester · Warrington · North Wales | 2 March 2026

Churches are among the United Kingdom’s most treasured architectural and cultural landmarks. From the soaring Gothic arches of medieval cathedrals to humble parish churches that have served their communities for centuries, these buildings hold layers of history, craftsmanship, and meaning. In our home city of Chester—with gems like Chester Cathedral, St John the Baptist in Chester, St Mary’s Church in Handbridge and Holy Trinity Hoole—such heritage is part of everyday life. Yet, despite their sturdy stone walls and historic significance, church buildings are not immune to fire. When fire does strike a historic church, the loss is deeply felt by the surrounding communities.

Recent Church Fires in the UK

St Mark’s Church, London

Here’s a recent example from north-west London, where a heritage-listed church building was heavily damaged by fire.

Another View of the Same Event

This incident reflects how quickly historic buildings can be compromised when a fire takes hold, and shows how destructive an uncontrolled fire can be—even with modern fire services responding.

Harleston Town Church Fire, Norfolk & Suffolk

Often these fires happen without injury, but the damage to timber structures and roofs in heritage churches can be profound.

What Causes Church Fires?

According to historic buildings specialists and insurers, the causes of fires in churches tend to fall into a few broad categories:

Electrical and Heating Faults

Older buildings often have complex electrical systems that have been updated piecemeal over time. Faulty wiring, overloaded circuits, or poorly installed modern equipment (such as lighting, heating or solar PV systems) are among the leading causes of accidental fires in churches.

Negligence and Accidental Ignition Sources

During events or maintenance work, heat sources such as candles, temporary heaters, or kitchen equipment can pose risks if not carefully managed. In ecclesiastical spaces, where wooden pews and fabrics abound, a small spark can escalate quickly.

Vandalism (Including Arson)

While most fires are accidental, arson and malicious damage do occur. Data from insurers and safety organisations shows over 150 UK churches have suffered arson attacks in recent years, costing millions of pounds in damage. This doesn’t make arson common relative to the total number of churches—but it does underscore the importance of security measures.

Environmental and Structural Factors

Older roofs, loft spaces, hidden cavities and lightning strikes can all increase fire risk. Many historic churches were built long before modern fire-safety standards existed, and the materials (timber roofs, lead flashings, intricate timbers) are often combustible by nature.

Fire Doors and Compartmentation

In many historic churches, fire doors and compartmentation were added long after the original building was constructed, often as part of later refurbishments or compliance upgrades. When fire doors are poorly specified, incorrectly installed or not routinely inspected and maintained, they may fail to perform their basic function of slowing the spread of smoke and fire.

Practical Ways to Prevent Church Fires

Here are well-established approaches that help protect these heritage sites:

1. Robust Fire Risk Assessments

Under the Regulatory Reform (Fire Safety) Order 2005, churches used as places of assembly or for community activities are required to have a suitable and sufficient fire risk assessment. The assessment should be conducted by a competent person. While you or a volunteer may be very familiar with your building, it is unlikely that you will be seen as competent in the eyes of UK fire safety legislation.

2. Professional Electrical Inspections

Electrical faults remain one of the most common causes of fires in non-domestic buildings, including churches. Electrical installations should be designed, installed and maintained in accordance with BS 7671 (IET Wiring Regulations). Periodic inspection and testing intervals are typically recommended every 5 years for fixed wiring in non-domestic premises, or sooner if the installation is heavily used or altered. Churches often accumulate additional systems over time, such as audio-visual equipment, lighting rigs and temporary power supplies, which should also be assessed. In heritage buildings, engineers with experience of historic fabric are particularly important to ensure safety improvements do not introduce new risks.

3. Early Detection and Response Systems

Fire detection and alarm systems should be designed and installed in accordance with BS 5839-1, which sets out categories of protection ranging from life safety systems to property protection systems. Many churches benefit from a Category L system to protect occupants during services and events, while some larger or particularly vulnerable buildings may also consider Category P systems aimed at early detection to limit fire damage. In heritage settings, careful detector selection and discreet cable routing can provide effective coverage without detracting from architectural features. Where systems are installed, regular testing, maintenance and user familiarisation are essential to ensure reliability.

4. Controlled Use of Heat Sources

The use of ignition sources such as candles, portable heaters, catering equipment and temporary installations should be carefully managed. BS 9999 highlights the importance of controlling ignition sources in places of assembly and ensuring separation from combustible materials. Churches should adopt clear written procedures covering candle use, heater placement, supervision during events and safe shutdown at the end of services. Particular care is needed during seasonal activities, concerts and community events, when temporary layouts or decorations may introduce additional risks.

5. Security Measures

Deliberate fires remain a recognised, though relatively infrequent, cause of church fires. BS 8220 (security of buildings) and guidance from insurers and fire authorities emphasise the value of layered security measures, including external lighting, secure doors and controlled access to vulnerable areas. CCTV can act as both a deterrent and an investigative aid. Many churches also find that regular opening and community presence reduces vandalism, as buildings that are visibly cared for and actively used tend to attract fewer malicious incidents.

6. Training and Preparedness

Fire safety arrangements are only effective if the people responsible understand them. BS 9999 and general fire safety guidance stress the importance of staff and volunteer training appropriate to the building and its use. This may include recognising fire risks, operating fire alarm systems, assisting evacuation, and using fire extinguishers where appropriate. For churches, training should reflect real usage patterns, including services, concerts, weddings and community events, ensuring that those present know how to respond calmly and effectively in the event of a fire.

7. Routine Fire Door Inspections

BS 8214 recommends that fire doors in non-domestic buildings are inspected at least every six months, with more frequent checks (quarterly) for doors that are heavily used or exposed to wear. Regular inspections help identify common issues such as damaged door leaves, excessive gaps, missing or degraded seals, faulty self-closing devices and unauthorised alterations. In historic church buildings, where fire doors are often retrofitted into older fabric, routine inspection is especially important to ensure doors continue to provide effective compartmentation without compromising the character of the building.
