1. Do They Actually Listen to You?
This is the one thing that separates a great wedding DJ from an average one. Before you even think about price or equipment, ask yourself — when you spoke to them, did they ask about you and your guests? Did they want to know what music you love, what you definitely don't want played, whether there are different age groups to consider?
A DJ who talks more than they listen will play the set they want to play, not the one your guests need. Look for someone who asks questions first.
2. Can They Read a Room?
No playlist survives contact with a real crowd intact. What works on paper at 7pm might not work at 10pm when three generations of family are on the floor together. Your DJ needs the experience and confidence to adapt on the fly — to read the energy in the room and respond to it.
Ask them directly: "What do you do if the dance floor empties?" A good DJ will have a clear answer. An inexperienced one will give you a vague non-answer.
3. Check Their Reviews — Specifically
Don't just count stars. Read what people actually said. The reviews that matter for weddings are the ones that mention:
- Communication before the event — did they stay in touch and make the couple feel looked after?
- Reading the crowd — did the dance floor stay full, even with a mixed age group?
- Flexibility on the night — did they take requests and handle last-minute changes smoothly?
- Professionalism — did they arrive early, set up without fuss, and present themselves well?
4. Are They Properly Insured?
This one surprises a lot of couples. Most wedding venues in London now require any supplier — including DJs — to carry Public Liability Insurance, usually a minimum of £5 million. Some require £10 million. Ask to see proof before you book.
Also ask whether their equipment is PAT tested (Portable Appliance Tested). This is a legal safety requirement and any professional DJ should have certificates to show.
5. Do They Offer a Pre-Event Planning Call?
The best wedding DJs don't just turn up and play. They'll want to speak with you in the weeks before your wedding to go through the running order, confirm timings, talk through any special moments (first dance, father of the bride song, last song of the night) and make sure nothing is left to chance.
If a DJ says they just need a playlist and a time to arrive, that's a red flag. Your wedding deserves more planning than that.
6. Can They Bring Equipment or Work With the Venue's Setup?
Some venues — particularly licensed clubs or hotels — have their own sound systems. Others are completely blank spaces where the DJ needs to bring everything. Make sure your DJ is clear on which situation applies to your venue and is comfortable in either scenario.
If they're bringing their own equipment, ask about their setup — speakers, lighting, DJ booth. A well-presented booth with good quality lighting makes a real difference to how the room feels during the evening reception.
The Bottom Line
When it comes to your wedding DJ, experience matters — but attitude matters more. What you want is someone who cares as much about your night as you do, who's done the prep work, who adapts to what your guests need and who makes the whole thing feel effortless.
Price should be the last thing you look at, not the first. The cheapest DJ at your wedding is rarely the best value.
