Picture this: you’re planning a dream wedding, a corporate gala, or a milestone birthday bash, and you’ve shortlisted a few mobile bar companies to bring the drinks and dazzle your guests. But with so many options, how do you choose the right one? A professional mobile bar hire checklist is your key to separating the amateurs from the experts. Asking the right questions to ask mobile bar suppliers ensures your event runs smoothly, your guests are impressed, and you avoid costly mistakes. This insider’s guide provides 10 essential questions to empower you to hire a reliable, high-quality event bar supplier. At Cosmo Events Ltd, we’ve seen it all, and we’re here to help you make an informed decision with confidence.
Whether you’re hosting an intimate gathering or a large-scale festival, the bar is often the heart of the event. A well-run mobile bar can elevate the atmosphere, while a poorly managed one can lead to long lines, subpar drinks, or even legal issues. Our event bar supplier checklist is designed to help you vet suppliers thoroughly, ensuring you partner with a team that aligns with your vision and delivers exceptional service. Let’s dive into the 10 questions that will guide you to the perfect mobile bar hire.
The 10 Essential Questions for Your Potential Bar Supplier
1. Are you fully insured?
Insurance is the foundation of any professional mobile bar service. Public Liability Insurance protects you, your guests, and the venue from accidents or damages, such as a spilled drink causing a slip or equipment damaging property. Without it, you could be held liable for costly mishaps. Ask the supplier to provide proof of their insurance policy and verify its validity. A reputable company will have coverage of at least £1 million and will share documentation without hesitation.
For example, imagine a guest trips over a poorly secured bar cable, resulting in an injury. A supplier with proper insurance ensures you’re not left footing the bill. Additionally, check if they have additional coverage like Employers’ Liability Insurance if they employ staff. This question demonstrates your due diligence and signals to the supplier that you expect professionalism.
2. What is included in your standard quote?
A transparent quote is a hallmark of a trustworthy supplier. When reviewing a quote, clarify exactly what’s included: glassware, ice, garnishes, mixers, bar equipment, staff, and even travel fees. Some companies may offer a low base price but tack on extras, inflating costs later. Ask for a detailed breakdown to compare suppliers accurately and avoid budget surprises.
For instance, a supplier might quote £5,000 for a bar package for weddings but exclude ice or glassware, which could add £500 or more. Ask if they provide premium garnishes like fresh herbs or citrus, and whether bar staff are included or charged hourly. A professional supplier will outline all inclusions upfront, helping you plan your budget with confidence. This question is critical for how to hire a mobile bar without hidden costs.

3. Can we create a custom cocktail menu?
A bespoke cocktail menu adds a personal touch that can make your event unforgettable. Whether it’s a signature drink inspired by your wedding theme or a corporate-branded cocktail, customization showcases a supplier’s creativity and expertise. Ask if they can craft unique drinks and whether they have experienced mixologists to execute them. Inquire about the process: Do they source special ingredients? Can they accommodate dietary preferences, like non-alcoholic or vegan options?
For example, at a recent outdoor festival, Cosmo Events created a “Summer Spritz” tailored to the client’s coastal theme, complete with edible flowers and locally sourced spirits. A supplier who can’t offer customization may lack the flexibility or skill to elevate your event. This question ensures your bar aligns with your vision and impresses your guests.
4. What experience do you have with our type of event or venue?
Every event is unique, and so are its challenges. A supplier experienced in corporate events may struggle with a rustic outdoor wedding, and vice versa. Ask for examples of similar events they’ve serviced, including the size, type, and venue specifics. Have they worked in marquees, historic venues, or outdoor fields? Do they understand the logistics of your event, like limited access or strict venue rules?
For instance, a supplier who’s only worked small private parties may not be equipped to handle a 500-guest festival with multiple bar stations. Ask how they’ve overcome venue-specific challenges, like setting up a bar on uneven ground or managing high guest volumes. Their answers will reveal their expertise and suitability for your event.
5. Who are the actual staff that will be at my event?
The staff behind the bar can make or break the guest experience. Professional mixologists bring flair, expertise, and efficiency, while untrained staff may struggle under pressure. Ask about the training and qualifications of the team who will work your event. Are they certified mixologists? Do they have experience with high-volume events? Will the supplier use subcontractors or their own trained team?
For example, a skilled mixologist can craft cocktails quickly while engaging guests, creating a lively atmosphere. In contrast, an inexperienced bartender might cause delays or serve inconsistent drinks. Ask if you can meet the team beforehand or see their credentials. This question ensures your guests receive top-tier service.
6. What are your setup and breakdown requirements?
Logistics are critical for a seamless event. Ask the supplier about their setup and breakdown needs: How much space do they require for the bar? Do they need power sources, like generators for outdoor events? How long will setup and breakdown take? These details help you coordinate with your venue and other vendors, like caterers or decorators.
For instance, a mobile bar might need a 3×3-meter space and access to a power outlet, which could affect your floor plan. If your event is outdoors, ask if they provide weatherproof equipment. A supplier who communicates clear requirements demonstrates professionalism and helps you avoid last-minute hiccups.
7. Can you provide testimonials or references?
Testimonials and references are powerful trust signals. A reputable supplier will have a portfolio of happy clients willing to vouch for their service. Ask for recent testimonials or contact details of past clients, ideally from events similar to yours. Check online reviews on platforms like Google or Trustpilot for additional insights.
For example, a glowing review from a corporate client who praised the supplier’s punctuality and drink quality can reassure you of their reliability. If a supplier hesitates to provide references, it’s a red flag. This step in your event bar supplier checklist ensures you’re partnering with a proven professional.
8. What is your policy for leftover alcohol?
If you’re supplying some or all of the alcohol, clarify how the supplier handles leftovers. Will they return unopened bottles? How do they manage opened bottles or excess stock? A clear policy prevents disputes and ensures you’re not left with wasted resources. For example, at a wedding, you might provide premium champagne but want unopened bottles returned for future use.
Ask if they charge a corkage fee for client-supplied alcohol and how they track inventory. A transparent supplier will have a straightforward policy, giving you confidence in their integrity. This question is especially important for cost-conscious clients.
9. What is your backup plan for unforeseen issues?
Even the best-planned events can face challenges, like running out of a key ingredient or equipment failure. Ask how the supplier prepares for these scenarios. Do they carry extra stock of popular items like ice or mixers? Do they have backup equipment, like a spare cocktail shaker or generator? A robust contingency plan shows foresight and reliability.
For example, during a recent Cosmo Events wedding, a sudden power outage was resolved with a backup generator, ensuring the bar ran smoothly. Ask for specific examples of how they’ve handled issues in the past. This question ensures your supplier can adapt under pressure.
10. What are the payment terms and cancellation policy?
Clear contract terms protect both you and the supplier. Ask about the deposit amount, payment schedule, and any additional fees, like overtime charges. What’s their cancellation or rescheduling policy? For instance, if bad weather forces you to postpone an outdoor event, will you lose your deposit? A fair, transparent policy prevents costly misunderstandings.
Request a sample contract to review terms in advance. A professional supplier will provide clear documentation and answer your questions confidently. This final question in your mobile bar hire checklist ensures you’re financially protected.
