Home Renovations and Refurbishments: How to Avoid Accidentally Compromising Your Fire Sprinkler System

Renovating a property is an exciting process. You may be refurbishing your own home, adding value to a real estate investment or upgrading a buy-to-let flat, but whatever the reasons, there are a wealth of benefits in terms of aesthetics, comfort, and resale potential. 

But it’s important to note that there are risks inherent in home renovations. As well as the financial outlay and time involved, you could also face the possibility of causing unplanned damage to the property, thus resulting in further costs and repairs. One particular risk that homeowners are often unaware of is related to fire sprinkler systems. 

Fire sprinkler systems in homes are generally installed and serviced in accordance with various fire safety standards and regulations. They are designed to sit there unobtrusively, springing into action with a torrent of water in the event of a fire breakout.

They will suppress or extinguish the flames, thereby saving the property and its inhabitants. But it is possible for building work to compromise these systems, either damaging them, reducing their efficacy, or suddenly rendering them non-compliant.

The following guide explains why you should pay careful attention to your fire sprinkler system during a home renovation, and the ways in which building work can interfere with it.

It also outlines how you can avoid these risks as well as highlighting the need for professional fire sprinkler servicing both before and after any project.

The Importance of a Home Fire Sprinkler System

A home fire sprinkler system is an incredibly useful life-saving technology. It is designed to activate via a smoke detector in the event of a fire, triggering a flow of water throughout the property that will suppress and reduce the spread of flame, thereby protecting the property and its occupants.

A fire sprinkler system is not always mandatory in residential buildings. In fact, in most homes it is not required as the risk and consequence of a fire is much lower than you’d find in a house of multiple occupation (HMO) or flat.

Whether or not a system is required depends on a range of factors such as the size, location, age, or occupancy of a particular property.

When in use, these systems are designed in accordance with nationally-recognised UK fire sprinkler standards. These include:

• BS 9251:2021 for domestic and residential systems

• BS EN 12845 for commercial or industrial buildings

These standards cover everything from installation through to inspection, maintenance and record keeping. I

t is essential for any property owner with a fire sprinkler system in place to ensure they remain compliant at all times. Not only for their own legal protection and peace of mind, but for the safety of everyone residing within the property.

It is an essential part of your responsibility, whether you are a homeowner or a landlord.

Any damage or obstruction to the workings can lead to performance issues, which may not be immediately obvious until a professional inspection is carried out.

In the meantime, the building may be left vulnerable. A home renovation or refurbishment can have this effect.

The Hidden Risks of Home Renovations

House renovations introduce several risks that can directly affect the effectiveness and compliance of fire sprinkler systems. These may include:

• Accidental Damage: Sprinkler pipes are often concealed within ceilings, floors and walls. When structural changes take place within a home, it’s very easy for pipework to be inadvertently damaged due to impact. This can lead to weakened connections or corrosion that can worsen over time.

• Obstructions: Major renovation work can interfere with the intended spray trajectory of sprinkler heads. Projects such as adjusting ceilings or installing lighting can get in the way of water flow, meaning the system will be less effective at suppressing flames. Care must be taken to ensure sprinkler coverage areas remain unobstructed.

• Alarm Isolation: During the building work, it may be necessary to turn off the system for a short while in order to complete adjacent construction. But if this is not done according to proper procedure, it can leave the building unprotected. Any alarm isolation must be performed in a controlled manner, with call centres and/or the fire brigade being notified of the works carried out.

• Changes to Layout: A fire sprinkler system can be rendered non-compliant even if no changes have been made to it. Simply altering the size of a room or converting a space can completely change the fire risk profile of a property, making a previously compliant system suddenly non-compliant.

How to Avoid These Risks: A Step-by-Step Approach

Fortunately, renovation work does not have to compromise your sprinkler system. With the right forward planning and awareness, the risks can be managed effectively. Here is a step-by-step approach to avoid the risks posed by home refurbishment.

Step 1: Review Your System

Before the work starts, have a specialist review your system comprehensively. This can help you map the layout of your pipes and identify any vulnerable areas. It will also give you an indication of your last fire sprinkler servicing date and ensure you are up to date and compliant with fire sprinkler standards.

Step 2: Share System Details with Contractors

If using contractors for renovation work, make sure they know where all sprinkler pipes and heads are located to prevent accidental damage.

Step 3: Physically Protect System

To minimise damage, apply temporary protection such as boarding or head covers if construction work is taking place nearby.

Step 4: Follow Correct Alarm Isolation Procedures

If alarm isolation is necessary, make sure to notify the fire brigade and call centres well in advance. Ensure the system is tested immediately after reinstatement.

Step 5: Inspect Post-Renovation

If you have made any structural changes to ceilings or room layouts, this may affect sprinkler coverage. Check to ensure heads remain unobstructed and positioned in line with fire sprinkler standards.

Step 6: Arrange a Fire Sprinkler Servicing

Once work is complete, book a professional fire sprinkler servicing to carry out necessary inspections and tests to confirm everything remains fully operational.

Step 7: Maintain Clear Records

It’s important to be able to show that the work has been completed in line with fire safety standards. Keep a full record of all inspection reports, isolation logs and compliance certificates to demonstrate due diligence.

Summary

In summary, home renovations and refurbishments can compromise sprinkler systems if carried out incorrectly. With careful planning and professional fire sprinkler servicing, you can ensure compliance and maintain reliable fire protection within your property.
