How to organise an office summer party in London

February 12, 2026

Summer parties are a great way to kick back, relax and enjoy the sunny weather in the company of good friends, family or colleagues. While the summer never sticks around for long in the UK, we want to help you make the best of it by giving you some tips for creating and hosting the perfect summer party in the heart of London. You don’t need to get out of the city to escape the city this summer!

Read on to find out the best organisation and planning tips to help you create a truly special summer party that you’ll be proud to host.

Summer party planning checklist

Parties are a lot easier to plan when you’ve got a theme to stick to – think of national holidays like Christmas, Halloween or even Valentine’s Day – but a summer party can often get stuck without direction. To counteract this, and to help you create a more specific plan, choose a nice summery theme for your party.

You could decide on a beach or pool party and fill your chosen venue with palm trees and fairy lights. Get inspired by summer events like Wimbledon or festivals to get people involved with either sports or music. You could even do a fiesta theme and get the pinata and sombreros involved!

Once you’ve picked your theme it then makes it easier to decide on décor, food and drinks…

Choose a venue

Easily the most important element of party planning is to find the right venue. You need somewhere that is big enough to cater for everyone at your company; somewhere central enough that people have easy access to transport home; somewhere impressive enough that it really feels special. At The Brewery, between May and August, two deck structures take centre stage in the courtyard. This seasonal space, called The Retreat, is the ideal setting for an office summer party.

Being comfortable is everything - especially when the weather is hot. You'll need shaded areas, sunny areas, comfortable seating, and shelter (should rain decide to show up).  The Retreat is fully furnished with comfy chairs and high tables surrounded by picturesque seasonal plants. Then there's the clear, raised roof that allows guests to remain outside, even if the heavens have opened.

Summer office party themes

Picking a theme can often 'make' the party. Whether it's a beach theme, all whit theme or an American-style BBQ theme, it gives your guests some guidance in terms of what they should wear and what they can expect. It will also make decorating the party venue a lot easier, not to mention the food and drink you'll be serving - although if you've found a quality venue, all of this should be taken care of. It will also impact the type of entertainment you get for the party.

Decide on your drinks

The best part of a summer party is that cocktails can be top of the menu! They’re not only easily customisable but also fun and refreshing for all your guests on a hot day. You can have a lot of fun with your theme when it comes to cocktails because there are so many different ones available.

For example, if you’re following a fiesta party theme, as we mentioned before, tequila sunrises could be a real hit. Additionally, how about Pimms for your guests at a Wimbledon themed party?

Whatever you choose as your cocktails, make sure you pay attention to what they’re served in too – fun and creative glassware can often be just as eye-catching as the drinks themselves. Don't forget to all add non-alcoholic cocktails and drinks to your list!

Create some tasty treats

Your guests won’t survive on cocktails and drinks alone, so it’s up to you to come up with a menu that will epitomise the summer party you’re hosting. Once again, your theme will be very handy for this, but you’ll first need to decide what kind of food you’re planning on offering.

Will you be providing a sit-down meal or is a buffet more your style? You probably won’t need to provide much in the way of hot food, since it’ll hopefully be warm, but maybe you’d like to have a BBQ?

Once you’ve made these decisions, you can then choose what you’d like to include. Maybe buffet items would work best for a fiesta-style party, such as spicy street food, or maybe a BBQ would fit the theme of a summer festival party.

If this sounds like too much work, why not call on the help of The Brewery’s fantastic team of chefs and hold your party at our venue? You’ll be able to take advantage of the summer menu we’ve created for our own summer parties if you book a party with us.

Indoor after party

A crucial feature of a great summer party is that the festivities don't have to end when the sun goes down. If it gets too chilly for your colleagues to remain outside, your venue should also provide indoor space that you can relocate to. At The Brewery, there is always an indoor space included in your summer party package.
