Commercial Drain Installations

Installing a new drain in the UK is subject to strict building regulations to ensure the health and safety of property occupants and the public, as well as to protect the environment. These rules are designed to ensure the drainage system is properly constructed and fit for purpose for the type of building, and to ensure the system doesn't contaminate water supplies, and efficiently removes waste water. At Plumbers 365, our qualified team of commercial drainage experts are fully compliant with all commercial building regulations and can manage the approval process for you such as:

• Compliance with Building Regulations: Part H of Building Regulations covers drainage and waste disposal, including the need for adequate drainage of foul and surface water.
• Building Control Approval: Approval from the Local Authority is required before work begins, unless carried out by a Building Regulations-approved contractor 
• Standards for materials and pipe gradients: Pipes must be correctly sized for commercial use and sloped to ensure proper flow and prevent blockages.
• Inspection requirements: The local council may inspect the installation at several stages.
• Connections to public sewer: Additional permissions are required from the local water authority if connecting to a public sewer.

Responsibility for drain connection depends on the point of connection and ownership of the drain or sewer. Our team of professionals drainage experts at Plumbers 365 can assess the situation and advise on:

• Property owner responsibility: You are responsible for all private drainage within your property boundary.
• Water authority responsibility: Once the drain crosses the boundary and becomes a public sewer, your local water company takes over responsibility.

• Plumbers  handle all required permissions and liaise with authorities.

Drainage experts at Plumbers 365 can assess your building and advise on fully compliant drainage requirements for your commercial property type. An office building may need many types of drainage, including:

• Foul water drainage: Removes waste from bathrooms, kitchens, and appliances.
• Surface water drainage: Channels rainwater away from roofs and hard surfaces, including gutters and downspouts.
• Combined drainage systems: Used in older properties, carrying both foul and surface water.
• Soakaway systems: Used where connection to a sewer isn’t possible; disperses water safely into the ground.
• Sustainable Drainage Systems (SuDS): Includes permeable paving and rain gardens to control runoff.

A restaurant or cafe building will require some additional drainage considerations to accommodate busy kitchens and adhere to hygiene regulations. Plumbers 365's drainage experts advise that the following should be considered:

• Grease traps: Intercepting fats, oils and grease and preventing them from entering the main drainage system prevents FOG related blockages and ensures proper wastewater management.
• Trench or slot drains: Different types of floor drains are available to dispose of excess water in busy areas, such as commercial kitchen sink areas where splashing water is common.
• Proper floor slope drainage: In areas where floor spills can be expected and cleanliness is a priority, such as a busy prep kitchen, proper floor sloping draining enables more efficient floor cleaning.

In addition to these types of drains, other considerations should be factored in when installing drainage in commercial restaurants and cafes, such as:

• Stainless steel components: Stainless steel is used often in commercial kitchens for it's hygienic properties, resistance to corrosion and durability.
• Regular maintenance: A restaurant or cafe should have regular drain inspections and maintenance to ensure blockages don't build up over time.
