Using modern tankers and specialist equipment, we ensure all waste is removed efficiently and disposed of in full compliance with environmental regulations. Whether you require planned maintenance or a rapid emergency response, Shanahan Contracting Ltd delivers a reliable and professional service that keeps your kitchen operating smoothly.

Why regular grease trap maintenance matters

Routine emptying and maintenance are essential to keep commercial kitchen drainage systems operating effectively and hygienically. Over time, FOG accumulates within the trap, reducing capacity and significantly increasing the risk of:

• Blocked drains and pipework
• Slow drainage and system back-ups
• Unpleasant odours
• Overflows and contamination risks
• Non-compliance with environmental and trade waste regulations

Without regular servicing, grease traps can quickly become a point of failure within a busy kitchen. This can lead to disruption of service, reputational damage, and costly reactive repairs.

A structured maintenance programme ensures your system continues to operate as intended, reduces the likelihood of emergency call-outs, and helps extend the lifespan of your drainage infrastructure.

Our grease trap cleaning process

When Shanahan Contracting Ltd carries out grease trap emptying, every stage is completed safely, cleanly, and with minimal disruption to your operations.

Our process typically includes:

• Accessing the grease trap and assessing its condition
• Full removal of FOG, wastewater, and solid waste using modern vacuum tankers
• Thorough internal cleaning of the trap, including walls, baffles, and components
• Checking inlet and outlet flows to ensure the system is functioning correctly
• Safe transport and licensed disposal of all waste in accordance with regulations

Before leaving site, our team ensures the grease trap is fully operational and highlights any defects, maintenance requirements, or early signs of failure.

• Today believe it or not I had the privilege of having my sceptic tank emptied by a Clive from Shanahan’s Strange as it may sound as it’s not a procedure I warm to but in this case it was a necessity! Firstly initial contact with the company who immediately recognised my dilemma and gave me the next available appointment at 7.30am the next day Then on time came CLIVE huge tanker and all, down our narrow drive. Twice he had to reverse some 60 yard to let neighbours get to work and an to an emergency dental appointment Once set up he emptied the tank only to find the soil pipe was blocked, to cut a long story short he sucked, blew, sucked again and eventually power jetted the blockage away (mechanically) that is staying nearly an hour in the process In this day and age people are quick to moan and complain and seldom, give praise but rest assured in Clive you have a real gem. Nothing is too much trouble. Amazon always ask How was your delivery? How many stars, was it on time, respect of property etc etc, but NEVER have I ticked the above and beyond but with Clive that box if there was such a box I would tick it. Well done and a big thank you to Clive
