What Questions Should I Ask Before Booking a Mobile DJ?

Hiring a mobile DJ is more than just finding someone with a playlist and a

speaker. Whether you're planning a wedding, corporate event, or private party, asking the right questions up front can save you from technical hiccups, last-minute cancellations, or awkward silences on the dancefloor.

Here are the essential questions to ask before booking a mobile DJ—straight from industry best practices and expert checklists.

1. Are You Fully Insured?

Any professional DJ should carry Public Liability Insurance (PLI). Many venues in the UK—especially licensed premises—require this before allowing performers to set up. Ask for proof of insurance and ensure it’s current and valid.

2. Do You Have a Written Contract?

A clear, written contract protects both parties. It should outline:

• Event date, time, and location

• Payment terms

• Cancellation policy

• Equipment provided

• Set-up and breakdown details

Avoid DJs who operate without a contract—verbal agreements can lead to misunderstandings or worse.

3. Is Your Equipment PAT Tested?

All electrical equipment used in public or commercial venues should be PAT (Portable Appliance Testing) certified. This ensures the gear is safe and meets legal standards. Venues often request to see up-to-date PAT certificates before allowing setup. It's worth noting that PAT testing is similar to an MOT test and only confirms the equipment is safe at the time of testing and is valid for 1 year. New equipment doesn't usually have to be PAT tested as the 1 year electrical guaruntee is sufficient. Futhermore, other equipment test may be valid providing the equipment is fit for use and the person completing the tests is competent.

4. Do You Have Backup Equipment?

Technical issues can happen. A professional DJ should always have backup gear—spare speakers, cables, laptops, and even lighting—ready to go in case of failure. Ask specifically about what backup systems they carry and how quickly they can respond to an equipment fault.

5. What Happens If You're Ill or Can't Make It?

Even the most reliable DJs can face emergencies. Make sure your DJ has a plan B—whether that means a network of trusted colleagues who can step in or a refund policy in the case of cancellation. You want assurance that your event won’t be left without music.

6. Can You Provide References or Reviews?

Reputable DJs should be able to supply testimonials or contactable references from past clients. You can also check independent review sites or social media for unfiltered feedback.

7. Do You Take Music Requests?

Some DJs offer set playlists; others welcome guest input or even take requests live on the night. Clarify whether they’ll tailor the music to your preferences and if they allow requests from guests.

8. What Time Will You Arrive for Setup?

Setup and sound checks are crucial. Ask how early they’ll arrive, how long setup takes, and whether they require access to certain power outlets or loading zones. Clear communication with your venue and other vendors is key.

9. Do You Offer Any Additional Services?

Some mobile DJs offer extras such as lighting effects, uplighting, photo booths, karaoke, or MC services. Ask about package options and pricing to see what best fits your event.

10. Have You Worked at This Venue Before?

While not essential, prior experience at your venue can be a bonus. It means the DJ may already be familiar with the layout, acoustics, and setup logistics, which can streamline the entire process.

Final Thoughts

The right questions will help you separate hobbyists from true professionals.

Don’t be afraid to get detailed—any seasoned mobile DJ will welcome your thoroughness and be happy to provide the reassurance you need to make your event a success.

Taking the time to ask upfront can make the difference between a night to remember and a night you’d rather forget.
