Where to Splurge vs Save

Some parts of your wedding deserve a big chunk of the budget. Others? Not so much.

💸 Spend More On:

• Venue & food – It's the backdrop and the bit people remember

• Entertainment – A great DJ = packed dancefloor = iconic night

• Photography/Videography – You only get one shot

• Lighting & Production – Transforms the vibe, especially in blank canvas venues

🧠 Save On:

• Favours – Most are left behind

• Paper invites – Digital or minimalist looks smart and saves cash

• Decor – Choose a beautiful venue and you won’t need much

• Flowers – Seasonal and local = cheaper and often better

Wedding Budget FAQs

What’s the average cost of a London wedding in 2025?

Expect to spend between £30,000 and £60,000 for a full-scale London wedding. Iconic venues, premium suppliers, and higher guest expectations all push prices well above national averages. It’s not unusual for central London weddings to hit £70k+ depending on style and size.

How much should go to the venue?

In London, venue and catering combined can easily eat up 65–75% of your entire budget. Typically, that breaks down as:

• Venue hire: 35–40%

• Food & drink: 30–35%

That means £24,000–£30,000 of a £40k–£50k budget may be gone before you’ve even thought about outfits or flowers.

How much does a wedding DJ cost in London?

For a proper setup – professional-grade sound, intelligent lighting, planning support, and a DJ who actually reads the room – you’re looking at £1,200–£2,500. Budget 8–10% of your total spend for evening entertainment if you want the dancefloor full all night.

Can you plan a wedding on £10,000 in London?

Realistically? Only if you go ultra-low guest count, off-peak weekday, and strip things right back. Even registry office weddings in London can cost £5k+ once you factor in outfits, meals, and the bare essentials.

Should I include a contingency fund?

Yes – and don’t skimp on it. 5–10% set aside for last-minute supplier changes, dodgy weather workarounds, or "didn't-think-of-that" moments will save your sanity later.
