Commercial & Domestic Sprinkler Industry Top 5 Potential Changes

1. Mandatory Sprinklers in New Care Homes (and Certain Residential Buildings)

• As of 2 March 2025, all newly built care homes in England must include a sprinkler system, irrespective of their height or size.
• The updated standard BS 9991:2024 — published November 2024 supports this requirement and sets out guidance for design, management and use of residential buildings including care homes.
• For the sprinkler industry, this creates a surge in demand from care‑home developers/builders, raising opportunities for installers, maintenance firms, and suppliers of sprinkler equipment.

Implication: Many more care‑home builds (and possibly other vulnerable-resident buildings) will require sprinklers — boosting demand and requiring scaling up of compliant design + installation capacity.

2. Transition Away from Old UK Fire‑Testing Standards — Move to European Standards

• From March 2025, the UK is phasing out the older fire‑reaction classifications (previously under BS 476) and aligning with the European classification system BS EN 13501.
• Under this shift, all new fire‑safety materials, building linings, and structural components must meet the more rigorous EN‑13501 criteria — impacting how passive fire protection (walls, doors, ceilings) is specified.
• This affects sprinkler-related systems indirectly: designers, specifiers, and contractors must ensure the whole building meets updated fire performance criteria — not just the sprinkler system. Many fire safety strategies will need overhaul.

Implication: The industry may see increased demand for integrated fire‑safety solutions combining sprinklers + compliant fire-resistant materials. Manufacturers and suppliers will need to ensure their products meet new classification standards.

3. Stricter Installation, Maintenance & Testing Standards — Updated Guidance for Sprinkler Systems

• The recognised guidance for sprinkler maintenance, LPC Technical Bulletin 203 (TB203), was updated in December 2024, changing how older sprinkler heads (over 25 years old) must be tested.
• Under the update: for low/medium risk buildings, fewer heads may be tested; for high‑risk buildings, more heads — and testing per environment/type is more detailed. Also, function-testing percentage and temperature-testing have increased.
• These changes signal tighter scrutiny on older sprinkler systems and a possible uptick in maintenance, retrofits, replacements — particularly in older buildings or those with legacy sprinkler installations.

Implication: Maintenance firms and compliance contractors will likely see increased demand. Building owners may need to budget for more rigorous testing, and possibly full system upgrades — raising demand for new installations or replacement parts.

4. Broadening Regulatory Expectations — Fire Safety Strategies, Documentation & Specialist Installations

• The recent update to Approved Document B (as part of the 2025 changes) includes enhanced requirements not only for sprinklers but for documentation under Regulation 38 and fire‑safety information handovers.
• The effect: builders, developers, and “responsible persons” will need to ensure full documentation and compliance evidence is provided — this increases the administrative burden of fire‑safety compliance.
• Additionally, with higher expectations for passive fire protection (due to EN‑13501 transition) combined with active systems (sprinklers), there’s growing demand for integrated fire‑safety design — bringing together passive and active systems.

Implication: The sprinkler industry may increasingly overlap with passive fire protection providers. Design coordination, documentation services, and compliance consultation may become part of many firms’ offerings, not just simple installation.

5. Market Growth Driven by Rising Regulatory Pressure and Demand for Modern, Integrated Fire‑Safety Solutions

• According to an industry study, the global fire sprinkler systems market — including demand from regulation-driven sectors — is forecast to grow strongly by 2034.
• The push for smarter, more adaptive sprinkler systems — for example integrating sensors, better suppression technologies, and systems suitable for a variety of fire types — is accelerating.
• As regulations tighten and older buildings are retrofitted — especially care homes, vulnerable‑resident housing, student accommodation, and high‑risk properties — we can expect sustained demand for updated, compliant, and possibly “smart” sprinkler systems.

Implication: The UK sprinkler industry is likely to expand significantly. Companies investing in modern sprinkler technologies, compliance services, and integrated fire‑safety design will likely be better positioned to benefit.

What currently governs domestic sprinklers in the UK

• The main standard for domestic and residential sprinkler systems is BS 9251:2021 (formerly BS 9251:2014). It covers houses, flats, maisonettes, HMOs, small hostels/B&Bs, blocks of flats, etc.
• Under BS 9251:2021, residential sprinklers are divided into four categories depending on building type and risk — from single‑family dwellings (Category 1) up to high‑rise flats (Category 4) above 18 m or about six storeys.
• The standard sets technical requirements: water supply (via mains or pump/tank), flow rates, number of heads, spacing, activation duration, maintenance, backflow protection etc.
• Domestic sprinklers are not universally mandatory across the UK — requirements vary by jurisdiction and by building type. For example: in England, new residential buildings over 11 metres tall must have automatic fire sprinkler systems.

So domestic sprinklers are already regulated — but only required in certain higher‑risk or taller residential buildings.

Top 5 Potential / Likely Changes Affecting Domestic Sprinklers

Here are five major trends or developments that could drive changes in how domestic sprinklers are used, regulated, installed, or maintained in future — and implications for homeowners, builders, and the sprinkler industry.

1. Regulatory Pressure to Expand Mandatory Sprinklers — Possibly to More Homes

• The National Fire Chiefs Council (NFCC) has publicly called on the government to strengthen sprinkler requirements, including:
  • mandating sprinklers in all new care homes, schools, and student accommodation regardless of building height.
  • introducing retrofits of sprinklers in existing residential buildings over a certain height (e.g., over 11 metres) based on risk assessments.
• While these calls currently focus on multi‑occupancy or higher‑risk properties, a successful push could influence regulations for domestic dwellings, particularly as part of broader fire‑safety reforms.
• In that scenario, more homeowners (especially those in flats, HMOs, converted homes or loft conversions) might be required — or strongly advised — to install sprinkler systems.

Implication: The domestic sprinkler market could expand significantly — beyond new builds or high-rise flats — to more “ordinary” homes. That could drive demand for retrofits, renovations, and compliance‑driven installations.

2. Upgraded Standards & Technical Requirements — More Robust, More Reliable Systems

• The update to BS 9251 in 2021 introduced a new Category 4 system to cover taller residential buildings (18 m+), with stricter requirements for water supply, backup power, monitored valves, and longer operation duration.
• The standard also expands the coverage to certain non‑residential ancillary areas within residential buildings (e.g., garages, bin stores, utility rooms, car parks ­— where relevant) under certain conditions.
• Enhanced installation and maintenance requirements (e.g. on water supply, backflow protection, monitoring) mean that modern domestic sprinkler systems are more like “life‑safety systems” rather than optional add‑ons.

Implication: As standards tighten, domestic sprinklers will become more elaborate and effective — which could increase installation and maintenance costs but also improve safety and reliability. Installers will need more technical expertise, and homeowners will need to treat sprinklers as a serious, regulated system (not a cosmetic or optional feature).

3. Growing Industry & Market Demand — Driven by Safety, Insurance & New Builds

• Many builders and fire‑safety firms highlight that domestic sprinkler systems are now widely used in new‑build homes and sometimes required during major renovations or conversions.
• Given the proven fire‑suppression performance (sprinklers can dramatically reduce fire damage and risk to life), there may be increasing interest from homeowner associations, landlords, insurers, and property developers to include sprinklers proactively — even where not mandated.
• As awareness of fire risk grows (especially after major fire disasters), demand could shift from “only high‑rise or high‑risk dwellings” to “ordinary homes wanting extra protection.”

Implication: There may be a gradual cultural shift: sprinklers become viewed as a standard home safety feature — akin to smoke alarms — for many UK homes, not just special buildings. This could open up a substantial market for retrofit sprinkler companies.

4. Retrofit & Renovation Trigger Points — More Sprinklers in Conversions & Loft Extensions

• Under regulations (and building‑control scrutiny), major renovations — loft conversions, floor‑plan changes, converting houses into flats/HMOs — may trigger requirements for sprinklers under certain circumstances.
• In homes where fire‑separation, staircases or escape routes are modified (e.g., single‑staircase conversions), sprinklers may be required to satisfy compliance.
• Given rising standards and increasing regulatory pressure (see point 1), more building‑control authorities may insist on sprinkler installation during conversions, not just in new builds.

Implication: Homeowners planning renovations or conversions may increasingly see sprinklers as a near‑inevitable cost. This could further expand domestic sprinkler penetration in older housing stock.

5. Risk-based Retrofitting & Broader Fire‑Safety Integration — Sprinklers + Passive Protection

• As calls grow (e.g., from the NFCC) for retrofitting sprinklers to existing high‑risk buildings (flats, HMOs, older stock), we may see more risk‑based assessments leading to selective retrofit programmes.
• At the same time, fire safety is becoming more holistic: sprinklers will likely be considered as part of a broader fire‑safety strategy integrating detection, suppression, escape routes, passive fire‑resistant materials, compartmentation, documentation, maintenance and regular inspection.
• Domestic sprinkler installation may increasingly be bundled with other fire‑safety upgrades — especially in multi‑occupancy buildings or conversions.

Implication: The domestic sprinkler industry might blur more with general fire‑safety construction/maintenance requiring collaboration with architects, passive‑fire specialists, building‑control bodies. The role of “sprinkler installers” could evolve into “full fire‑safety consultants/contractors.”

Challenges & Barriers for Domestic Sprinkler Expansion

While there is strong momentum toward growth, some obstacles remain and could limit how widely domestic sprinklers spread.

• Cost: Installing a full BS 9251-compliant sprinkler system (especially with pump & tank, monitoring, maintenance) may be seen as expensive particularly in older houses or conversions.
• Water supply / infrastructure constraints: Not all homes will have the water flow or pressure required; retrofitting may require dedicated tanks/pumps.
• Regulation inconsistency across UK regions: Requirements differ between England, Wales, Scotland — and some jurisdictions may not mandate sprinklers in many domestic properties.
• Awareness and perceived necessity: Many homeowners may still consider smoke alarms sufficient or view sprinklers as overkill, especially in low-rise houses.
• Maintenance burden: Sprinkler systems need maintenance, inspection, possible upgrades which can discourage some homeowners.

What This Means for Stakeholders (Homeowners, Builders, Fire‑Safety Firms)

• Homeowners / landlords / property developers: If you plan a conversion, loft extension, HMO, or build a new flat/house — fitting a sprinkler may soon be near‑standard, and often advisable for life safety and insurance purposes.
• Builders & contractors: There may be increased demand for domestic sprinkler installation especially retrofit and conversion work. Builders without sprinkler‑installation skills may partner with or subcontract to specialist firms.
• Fire‑safety firms / sprinkler companies: Opportunity to grow more domestic clients, broader market. But success depends on offering compliant, robust, maintainable systems possibly integrating with passive fire safety.
• Regulators and insurers: Sprinklers may become more strongly recommended (or required) in guidance, not just in high‑risk buildings. Insurance providers might incentivise homes with sprinklers via lower premiums.
• Policy‑makers / advocacy groups (e.g. NFCC): Clean opportunity to push for broader regulation, especially in light of fire risks in older housing stock and multi-occupancy dwellings.

Outlook: What Could Happen in the Next 5–10 Years

Putting together current standards, regulatory pressure, market demand, and fire‑safety priorities — these are plausible trajectories for domestic sprinklers:

• Widening of mandatory sprinkler requirements to more new builds (even low-rise), or stricter enforcement at renovation/conversion time.
• Growth of retrofit programmes especially in older flats, HMOs, large houses often triggered by risk assessments, insurance, or building upgrades.
• Domestic sprinklers increasingly integrated into broader fire‑safety packages for homes: detection, passive fire protections, escape routes, documentation.
• Rise of specialist fire‑safety consultancies / installers focused on domestic and mixed residential buildings, offering full compliance + maintenance services.
• Gradual cultural shift: domestic sprinklers seen as a standard safety feature in UK homes — like smoke alarms, carbon‑monoxide detectors, etc.
