Bespoke Planned Preventative Maintenance (PPM)
Move your business from a position of risk to a position of control. We design tailored maintenance schedules that ensure compliance, reduce downtime, and drastically cut your commercial energy costs.



Stop Gambling with Your Facility's Infrastructure
The reactive “fix it when it breaks” approach is a dangerous gamble. Waiting for a critical failure – often during the coldest months when your system is under the most stress – leads to higher emergency call-out fees, inflated parts costs, and extended periods of business downtime.
The PPM Solution
Commercial planned preventive maintenance is a proactive strategic investment. We implement a systematic schedule of checks, servicing, and minor repairs designed to identify and address issues long before they escalate. This proactive mindset protects your business, your people, and your bottom line.












Why Facilities Managers Trust SEM with Their Assets
We deliver comprehensive commercial gas and heating solutions for facilities across the South East. Whether you manage a single luxury residential block or a multi-site corporate portfolio, our Gas Safe engineers are equipped to maintain, repair, and upgrade your critical plant room infrastructure.
Significant Cost Savings
Emergency repairs are almost always more expensive than scheduled maintenance. A study by the U.S. Department of Energy found that a well-maintained commercial heating system can save up to 30% on energy costs by running efficiently.
Total Legal Compliance
The Gas Safety (Installation and Use) Regulations 1998 mandate that all commercial gas systems are maintained safely. We ensure total compliance to protect your staff from risks like carbon monoxide leaks.
Improved Energy Efficiency
Over time, dust, dirt, and corrosion build up, forcing your system to work harder. According to the Carbon Trust, maintaining heating and hot water systems reduces energy use by up to 10-15%.
Better Asset Management
Your heating system is a massive capital investment. A detailed PPM schedule provides a clear performance history, allowing you to accurately predict component replacements and budget for future upgrades without sudden financial shocks.
A Unified Approach to Building Maintenance
We do not offer generic, off-the-shelf packages. We conduct a full site audit to design a PPM schedule tailored strictly to the demands of your facility, combining all of our core services into one seamless contract:

Preventative Maintenance FAQs
Will a PPM contract actually save us money?
Yes. Emergency repairs are incredibly costly due to emergency call-out fees, expedited parts shipping, and business interruption. By servicing equipment regularly, you dramatically extend its lifespan, reduce your monthly utility bills through better efficiency, and avert sudden capital expenses.
How often will engineers need to visit our site?
This is entirely bespoke to your facility. Following a comprehensive site audit, we design a schedule that meets your legal obligations (such as annual CP12s and Legionella risk assessments) while integrating seamlessly with your operational hours to ensure zero disruption to your business.
Does PPM improve our building's air quality?
Absolutely. A well-maintained heating and ventilation system contributes directly to a healthier indoor environment. By keeping filters clean and ensuring proper ventilation, a PPM plan reduces allergens and provides a consistent, comfortable temperature for your staff and customers.
