How much does commercial planned maintenance cost?

Costs depend on your property size, drainage complexity, and how often maintenance is needed. A small retail unit might need quarterly jetting at a few hundred pounds per year. A large restaurant or food production site might need monthly visits. We'll survey your site and give you a fixed annual quote.

What does planned maintenance include?

A typical maintenance visit includes high-pressure jetting to clear buildup before it becomes a blockage, CCTV inspection to check for developing problems, clearing of gullies and interceptors, and a written report on drainage condition. We'll tailor the schedule to what your property actually needs.

How often should commercial drains be maintained?

It depends on your business. Restaurants and food businesses typically need monthly maintenance due to grease buildup. Offices and retail might only need quarterly visits. High-use facilities like schools or care homes usually benefit from bi-monthly schedules. We'll recommend a frequency based on your site survey.

Can you maintain drains across multiple sites?

Yes. We work with landlords, property managers, and businesses with multiple locations across Southern England. One contract, one point of contact, consistent service across all your sites. We can also provide consolidated reporting and invoicing.

What happens if there's a problem between maintenance visits?

Planned maintenance clients get priority emergency response. If something goes wrong, you go to the front of the queue. Emergency callouts are charged at our standard rates - no premium because it's outside your scheduled visits.

Do you maintain grease traps?

Yes. For restaurants, takeaways, and food production facilities, grease trap maintenance is often the most important part of a drainage schedule. We'll empty, clean, and inspect grease traps as part of your maintenance plan - or as a standalone service if you prefer.

Can I see a sample maintenance report?

Yes. We're happy to show you examples of our maintenance reports before you commit. You'll see the level of detail we provide and how we document findings, recommendations, and work completed.

How do I get started with planned maintenance?

Call us or request a callback. We'll arrange a site survey to understand your drainage layout, usage patterns, and any existing issues. Then we'll recommend a maintenance schedule and give you a fixed annual quote. No obligation until you're happy to proceed.

Can planned maintenance help with insurance or compliance?

Yes. Regular documented maintenance demonstrates you're taking reasonable steps to prevent drainage failures. Our reports provide evidence for insurance purposes, health and safety compliance, and due diligence requirements. Some insurers offer better terms for properties with documented maintenance schedules.
