Regulatory Compliance With Commercial Sprinklers in London
We work closely with clients who manage commercial properties to ensure compliance with fire regulations and to protect their properties from fire risks by installing commercial fire sprinkler systems.
New commercial properties in London, and all commercial properties that are generally industrial, storage, and distribution, fall under Category B of the Building Regulations. This requires that fire sprinkler systems be installed in new, converted, and high-risk commercial buildings. High-risk includes structures at least 18m high or having 7+ stories, as well as structures that regularly hold flammable materials and buildings with timber structures.
Sprinklers are often installed in other commercial properties, including hotels, retail stores, office buildings, and other structures, despite not necessarily having a legal obligation to do so.
We’ll design and supply Wet Pipe Systems, Dry Pipe Systems, Pre-action Systems, and Deluge Systems.
We ensure compliance with BS EN 12845, the principal guidance for fire sprinkler installation. BS EN 12845 aims to ensure optimal protection in the event of a fire hazard. We provide thorough risk assessments and work with leading system manufacturers to design and install a system that best suits your needs and provides legal compliance. Even with the most complex projects, our team excels at overcoming challenges, and we always design innovative solutions that suit your building, aiming to minimise disruption when installing your system wherever possible.
Leading Designers & Installers of Domestic Fire Sprinklers in London
Domestic fire sprinkler systems are becoming more common for apartment blocks and flats due to legislation that makes them a legal requirement for buildings over 11m in height. They are also a key system in protecting your property in the event of a fire, and investing in fire sprinkler systems can result in reductions in your home insurance premiums each year. They are a great system to consider if you want to improve the safety of your home.
Whether you’re looking to develop a single domestic dwelling, several houses, or you’re carrying out property renovations, we’ll use VR walkthroughs and AI-driven data to ensure a seamless project. With years of experience working with domestic fire sprinkler systems across London, we’ll provide you with a tailored solution and proven fire safety methods.
Residential Fire Sprinkler Installation in London
We are also experts in residential fire sprinkler systems installation, which are ideally suited for student accommodation, care homes, nursing homes, multi-occupancy properties, and apartment buildings/flats.
Our Design Process
We will assess the building and design a system that is tailored to the property, which meets your specific needs and provides protection for residents and staff. All of our fire sprinkler installations are carried out in strict accordance with all UK legislation. This includes compliance with BS EN 12845 and Category B compliance and design under LPC Hazard Categories.
Our Consultation Process
We provide tailored individual consultation and designs for our clients. Not one project is the same, so we approach each project to assess your requirements and then create a design that suits you and fully protects the building, as well as being legally compliant.
Retrofit & Upgrading Current Systems
We are also able to retrofit and upgrade current systems, should you require this. We have retrofitted many different properties and blocks of buildings to ensure that you can upgrade a system where needed, or if you have been required to upgrade for compliance purposes or after a fire risk assessment.
We understand that challenges can be caused due to disruption when having to upgrade any property, so we aim to minimise these where possible, and we will provide a strict schedule of how long and when the works will be completed. We also appoint a Tenant Liaison Officer for residential building projects, who oversees the project and communicates with tenants and any staff on site throughout the project.
We’ll also be able to work on the following during a retrofitting project:
- Boxing and containment,
- Asbestos surveys and removal,
- Third-party fire stopping,
- Electrical supplies and UPS systems,
- Concrete bases and other building supplies.
If you require an upgrade to your existing fire sprinkler system or want to retrofit additional features or upgrades, get in touch with our team to discuss your project.
The Aftercare of Your System With Professional Servicing and Maintenance

FAQs
Are Fire Sprinklers Required By Law In The UK?
Fire sprinklers are not universally mandatory in all UK buildings. They are, however, legally required for new or converted residential buildings over 11 metres in England, as per BS 9251:2021. Buildings of 20,000 square metres or more are also legally required to have fire sprinklers under UK Building Regulations Part B.
Sprinklers are also recommended in buildings with specific fire hazards, like those storing hazardous materials or that are high-occupancy spaces.
What Is A ‘Policy D12 Fire Statement’ And Do I Need One?
If your project is in London, the London Plan (Policy D12) requires nearly all new developments, from major high-rises to large-scale conversions, to submit a formal Fire Statement at the planning stage. A Fire Statement is a standalone document which defines the fire safety objectives and performance records of a development, and how these objectives will be provided or satisfied. The overall goal of Policy D12 is to establish fire safety requirements to be considered in the early stages of design of all new developments in London, to enhance occupant safety, improve fire resistance and facilitate efficient emergency response. A Fire Safety Statement is required for new developments and major refurbishments. While full Fire Statements are usually required for major developments, simple house extensions and other such works must still demonstrate how they meet Policy D12 fire safety objectives.
Do I Need A Fire Statement For A ‘Permitted Development’ Project?
In London, even if you are completing work under Permitted Development, you must still comply with London Plan Policy D12. This means providing a fire safety statement. We can support you in providing the technical sprinkler data, which shows that your planned works do not compromise the safety of the occupants or neighbours.
Is It Mandatory To Install Sprinklers In All New Build Houses?
Under current Approved Document B guidelines, sprinklers are not yet mandatory for all single-dwelling houses. However, they are mandatory for:
- New residential blocks with a floor over 11 metres,
- New care homes, regardless of their height.
Some London boroughs and councils are pushing for smaller new-build projects to include fire sprinkler systems. For example, the borough of Bromley made calls to mandate sprinklers in all new-build flats, citing fire safety concerns. Following the Grenfell Tower disaster, Wandsworth council also moved to mandate sprinklers in all new council-backed developments, beginning a retrofitting program for existing blocks.
Why Are Fire Sprinklers Important In London’s Tight Streets?
Densely populated areas of the city, such as Soho, Hackney, or Islington, often lack the legally required 45-metre fire brigade vehicular access. Installing a fire sprinkler system is a solution which compensates for poor fire engine access, providing time for people to escape and prevent the fire from spreading to neighbouring properties, which is especially vital where traditional fire engine access is challenging and slow.
How Does The London Fire Brigade View Residential Sprinklers?
The London Fire Brigade strongly advocates for the installation of residential fire sprinkler systems. They view them as highly effective in protecting lives, reducing property damage and ensuring firefighter safety. They actively campaign for greater mandatory requirements of sprinklers in new developments and retrofitting in high-risk, existing residential buildings.
I’m Planning A Loft Conversion. Do I Legally Need Fire Sprinklers?
Under Approved Document B, a loft conversion often turns a two-storey house into a three-storey one. This work will typically require a ‘protected escape route’ which includes fire doors and partitions. However, if you prefer an open-plan layout, installing a residential sprinkler system is the common way to satisfy Building Control while keeping your design open.
I’m Working On A Basement Extension. Are Sprinklers Required?
Basement extensions are a popular solution for expanding living space in prime areas of London; they do present challenges surrounding ventilation and access for the London Fire Brigade. If your basement lacks natural ventilation, Building Control will likely require Fire Sprinklers to control fires and allow for safer evacuation.
What Fire Sprinkler System Is Required For A House of Multiple Occupancy (HMO)?
An HMO is classified as a residential building. Whilst fire sprinkler systems are not always mandatory in Houses of Multiple Occupancy, they are required for higher-risk buildings, conversions of non-residential properties, or large, multi-storey developments, particularly if escape routes are limited.
Some local authorities often use their discretionary powers to make fire sprinkler systems mandatory for HMO licensing for higher-risk, larger properties, even if not explicitly required by national Building Regulations.
We Are Building A High-Rise Residential Block. What Is The Current Fire Sprinkler Guidance?
In 2026, guidance on fire sprinklers in high-rise residential buildings in England was significantly strengthened following the Grenfell Tower tragedy. Amendments were made to Approved Document B (Fire Safety), with mandatory requirements introduced for buildings over 11 metres in height. They must have automatic fire suppression systems, designed and installed in accordance with BS 9251 for residential buildings.
For buildings between 11m and 18m in height, the requirements typically apply to new-build blocks of flats. For existing buildings, retrofitting is generally required under a material alteration.
What Are The New 2026 Evacuation Plan Rules For London High-Rises?
Starting April 2026, new UK regulations (Fire Safety (Residential Evacuation Plans) (England) Regulations 2025) introduce a process called Residential Personal Emergency Evacuation Plans (RPEEPs). These will apply to multi-occupied residential buildings that contain two or more domestic premises and are either 18 metres or seven storeys or higher, or over 11 metres in height, where a simultaneous evacuation strategy is in place. These regulations also place new legal requirements on Responsible Persons, typically building owners, landlords or managers. To better understand the new UK Fire Safety (Residential Evacuation Plans)(England) Regulations 2025, read our guide here.
Does A Fire Sprinkler System Need Maintenance?
To remain compliant and ensure your insurance policy is valid, you should service your sprinkler system annually. This will involve checking water pressure, testing pumps and ensuring that all the heads are unobstructed. Having a qualified specialist check your fire sprinkler system will ensure you comply with safety regulations, insurance requirements, and that the system remains functional.
Who’s Responsible For The Annual Servicing In A Block Of Flats?
In a residential block, the Freeholder or Management Company is usually responsible for the annual maintenance and servicing of a fire sprinkler system. However, individual leaseholders must ensure that the sprinkler heads inside their flats are not painted over or covered.
Will Fire Sprinklers Affect My Insurance?
Installing fire sprinklers can often positively affect your insurance premiums. Many insurers view them as a good way to lower the property’s risk, as they can control or extinguish fires, minimising damage, which leads to lower claims and decreased downtime.
Can A Sprinkler Have A False Alarm?
This is very rare. It’s a common Hollywood myth that a burnt piece of toast, or similar, could set off every sprinkler in the building. Every sprinkler head will be independent and heat-activated. Therefore, only the head directly above the fire will trigger. Often, a fire can be controlled or extinguished by just one or two heads.
Do Sprinklers Create More Water Damage Than The Fire And Rescue Service?
A sprinkler head will discharge between 35 and 100 litres per minute, depending on the system’s design. This water will be discharged around 10 to 30 seconds after the fire produces enough heat to trigger the system. No fire brigade will be able to arrive at the scene and act in less than 5 to 10 minutes, and when the fire crews arrive, they will pump a large amount of water to compensate for the delay. This is usually around 1000 to 3000 litres of water per minute, which will create more water damage.
