Why Maintenance Matters

What Happens When Drainage Maintenance Is Neglected

For facilities managers and building owners, drainage is invisible — until it fails. Neglected drainage systems in commercial properties lead to problems that go far beyond a blocked pipe:

  • Emergency call-outs at unsociable hours costing double or triple standard rates
  • Tenant complaints, reputational damage and lease disputes
  • Health code violations in restaurants, hotels and commercial kitchens
  • Revenue loss from forced closures — a blocked kitchen drain can shut a restaurant mid-service
  • Insurance complications from damage that was preventable with routine maintenance

Scheduled drainage maintenance should be treated with the same priority as fire alarm testing or legionella checks. It is not optional — it is a core part of building compliance and operational resilience.

Case Study

Major Central London Co-Working Provider
Major Central London Co-Working Provider
The Problem

A leading co-working operator managing over 70 buildings across central London had no centralised drainage maintenance programme. Individual buildings were calling out emergency contractors reactively, resulting in inconsistent service, high costs, and repeated failures in the same locations.

What We Did

LDS conducted free site surveys across the portfolio and designed a bespoke PPM programme covering all 70+ sites. Each building received a tailored maintenance schedule based on its size, usage, and drainage infrastructure. Our dedicated PPM team now attends each site at agreed intervals to carry out CCTV inspections, high-pressure jetting, gully cleaning, and full condition reporting.

The Outcome

Emergency call-outs across the portfolio dropped significantly within the first 12 months. The client now receives consistent condition reports for every building, giving their facilities team full visibility of drainage health across the estate. Maintenance costs became predictable and budgetable rather than reactive and variable.

Drainage Maintenance Contracts

Why Choose a Maintenance Contract

A planned approach to drainage maintenance protects your property, your tenants, and your bottom line.

Reduce Emergency Call-Out Costs

PPM clients experience significantly fewer emergency drainage incidents. Scheduled maintenance catches problems before they become 3am emergencies.

Protect Revenue

A blocked kitchen drain can force a restaurant to close. A flooded office floor displaces an entire team. Scheduled maintenance prevents this.

Compliance & Duty of Care

Meet your obligations under building regulations and health and safety requirements. Documented maintenance records for audits and insurance.

One Contractor, Complete Coverage

CCTV surveys, jetting, cleaning, and repairs from one team. No need to coordinate multiple suppliers.

Drainage Maintenance Contracts

Frequently Asked Questions

What does a drainage maintenance contract include?
Every contract includes three core elements: scheduled CCTV drain surveys and inspections, high-pressure drain cleaning and jetting, and detailed post-visit reporting with photos, video, and prioritised recommendations. The exact scope is tailored to your property after a free site survey.
How much does a PPM contract cost?
Contracts vary depending on property size, number of sites, and scope of work. We provide a free site survey and detailed quote with no obligation so you can see exactly what is included before committing.
How often should commercial drains be maintained?
It depends on property type. Restaurants and commercial kitchens typically need monthly maintenance. Hotels benefit from quarterly visits. Offices and residential blocks usually require servicing every 6 to 12 months. We recommend specific frequencies after surveying your property.
Can you work outside business hours?
Yes. Our PPM team regularly works nights, weekends, and around operational hours. Hotels, restaurants, and co-working spaces often require overnight access, and we schedule accordingly.
Do you provide reports after each visit?
Yes. After every visit you receive a detailed condition report including CCTV footage, photographs, a defect log with priority ratings, and recommendations for any further work.
What areas of London do you cover?
We cover all London boroughs plus the Home Counties. We currently maintain over 70 buildings across central London for a single client, so multi-site coverage is a core strength.
Can you maintain multiple sites under one contract?
Yes. We currently manage multi-site portfolios across London for co-working operators and property managers. A single contract with one point of contact simplifies your facilities management.
What accreditations do you hold?
We are accredited by the National Association of Drainage Contractors (NADC) and hold CHAS certification. Our engineers are fully qualified professionals.
What happens if you find a problem during a PPM visit?
Any issues found are flagged in the post-visit report with a priority rating. We provide a separate quote for any repairs needed. If the issue is urgent, we can often action it on the same day.
How do I get started?
Request a free site survey. We visit your property, assess the drainage system, and provide a detailed proposal within a few working days.
