Your Company at Its Most Relaxed

The best corporate summer parties feel effortless. They’re anything but. Behind every relaxed afternoon is a plan for the weather, the food, the guest experience and the hundreds of small decisions that make people feel looked after. The feedback we hear most often isn’t about the headline entertainment. It’s about the details nobody had to think about. From garden parties and rooftop gatherings to large-scale outdoor celebrations, we work as an extension of your HR, internal communications and events teams. One team. One point of contact.

Recent summer parties. Trainline: 900 staff at York Lawns in Regent’s Park, with 93% satisfaction. SilverDoor’s 25th: 400 guests at Amber Lakes. One festival in four cities, with 500+ in London. A summer away day for 500 at Hawker House. 600 employees and their families at Tulley’s Farm.

The Real Measure of a Summer Party

The Morning After Test

The best summer parties aren’t remembered because they looked impressive. They’re remembered because they felt effortless to be part of. The ones that land usually get three things right:

  1. A smooth arrival
    The first few minutes set the tone for everything that follows.
  2. Space to opt in
    Great events make room for every personality, not just the loudest voices.
  3. A memorable finish
    The final moments are often the ones people talk about most afterwards.

Our approach

Nothing Left to Chance

Great summer parties feel spontaneous. The planning behind them isn’t. From the first venue visit to the final guest departure, every detail is considered around your audience, your brand and your site. Weather contingency, guest communications, budget, entertainment, catering, production and logistics all work together as one joined-up plan.

The rain plan. Every outdoor party we run gets a written wet-weather plan before anything is booked. It names who makes the call and by when, what moves where, and how long the switch takes. At SilverDoor’s 25th at Amber Lakes, we watched the wind all day and adjusted the stage anchoring as it changed. Ask to see a sample plan.

Planning next summer’s party? We can help a year ahead or at the last minute. Trainline’s festival for 900 took seven months from first idea to the day; we’ve also delivered summer parties in under six weeks. The best July dates at outdoor venues go early, so if you want a marquee or 500+ guests, talk to us this autumn.

Looking for corporate summer party venues in London? We’ve taken over York Lawns in Regent’s Park twice, run a party for 400 at Pergola Paddington, and further out, built a festival at Tulley’s Farm and a Greek-themed party for 200 at Pangdean Old Barn.

FAQs

Explore our Summer Party FAQs

When should we start planning our corporate summer party?

For most corporate summer parties, we recommend starting planning three to six months in advance. This gives you the best choice of venues, entertainment, suppliers and dates, particularly for garden parties, rooftop events and larger company celebrations.

Popular London rooftops, private gardens, country estates and marquee venues can book up quickly during the summer season. Planning earlier also allows more time for site visits, production design and weather contingency planning.

We have delivered successful summer parties on much shorter timelines, including events planned in under six weeks. However, shorter lead times usually require greater flexibility around venue choice, location and event date.

If you’re at the early planning stage, our corporate summer party planning guide for 200 guests covers timelines, venues, budgets and practical considerations in more detail.

What types of corporate summer parties do you deliver?

We deliver a wide range of corporate summer parties, including garden parties, marquee events, rooftop celebrations, family fun days, themed summer events, barbecue parties and large-scale employee celebrations.

The format always follows your audience, objectives and venue. Some clients want a relaxed afternoon in the sunshine, while others prefer a more structured programme with entertainment, activities, great food and opportunities for people to connect.

Whether you’re bringing together 100 guests or 900, every summer party is designed around the experience you want your people to have.

How much does a corporate summer party cost in the UK?

Corporate summer party budgets typically range from £100 to £500+ per guest, depending on venue, catering, entertainment, production and format. At MGN Events, most summer parties start from around £200 a head, and most budgets start at around £50,000. Audience size changes the per-head cost more than anything else: 600 guests share the venue, production and staffing costs across far more people than a group of 50, so the price per person comes down as numbers go up. We scope every project to your brief and break the charges down clearly, so you can see exactly where the budget goes. Our summer party cost guide has a realistic per-head breakdown.

How do you handle bad weather for outdoor summer parties?

Every outdoor summer party we deliver includes a site-specific wet-weather plan. Depending on the venue, this may include covered structures, sheltered walkways, flooring, heating, alternative layouts and a clear decision-making process for changing conditions.

British summers are unpredictable, so weather planning is built into the event from the start rather than treated as a last-minute contingency. The goal is simple: your guests should enjoy the event regardless of the forecast.

Our own production team has been delivering outdoor corporate events since 2008. Your audience shouldn’t notice the weather plan. They should simply notice that the event ran smoothly.

Can you help us find a corporate summer party venue in London?

Yes. Venue finding is part of how we plan, and it is free of charge. For a summer party in London the options usually fall into five types: rooftops and terraces, gardens and parkland, riverside venues, a marquee on your own grounds, or a transformed office or car park.

We shortlist venues against your guest numbers, budget and wet-weather plan, visit them with you, then handle the contract and the logistics. Our guide to summer party venues explains how to choose, and our venue finding service page explains how it works.

Can you run a summer party at our office, car park or company grounds?

Yes. We regularly transform offices, car parks, courtyards, rooftops, warehouses and company grounds into fully functioning summer party venues across London and the UK.

Our production team manages everything needed to make the space event-ready, including temporary structures, flooring, power, lighting, sound, catering infrastructure and licensing requirements.

Hosting your summer party on site can reduce travel costs, minimise disruption and make attendance easier for your guests. We’ll carry out a full site visit and design the event around access, logistics, neighbours, noise management and operational requirements.

What makes a corporate summer party memorable, rather than forgettable?

The most memorable corporate summer parties usually get three things right:

A strong arrival
The first few minutes set expectations for everything that follows.

Space for everyone to enjoy the day their way
Not every guest wants to be at the centre of the action. Great summer parties create room for different personalities, energy levels and ways of engaging.

A memorable finish
The final moments often become the story people take home and talk about afterwards.

Creative concepts, entertainment, production and catering all matter. But they’re most effective when they’re built on an event experience that works from beginning to end.

How do you know a corporate summer party is worth the investment?

A successful corporate summer party should leave people feeling appreciated, connected and positive about the organisation they work for. While every business measures success differently, many clients look at attendance rates, employee feedback, engagement scores and post-event sentiment to understand the impact.

The strongest summer parties create shared experiences that people continue talking about long after the event itself. They give teams a chance to celebrate achievements, spend time together outside their usual working environment and strengthen relationships across the business.

We can build feedback and measurement into the event process, helping you understand what resonated with your audience and where the greatest value was created.

Can we include families and children in a corporate summer party?

Yes. Many organisations choose to include partners, children and wider family members as part of their corporate summer celebration, particularly when they want to create a more inclusive event experience.

Family-inclusive summer parties require additional planning around children’s activities, safeguarding, first aid, catering and guest welfare. We design age-appropriate experiences alongside the main event so that both adults and children can enjoy the day.

We’ve delivered family-inclusive summer celebrations for audiences of more than 600 guests, including employees, partners, children and even dogs. If a dedicated family event is your primary objective, we can also advise on the differences between a corporate summer party and a family fun day.

If the event is primarily focused on employees and their families, a dedicated family fun day may be a better fit than a traditional corporate summer party.

How do we avoid the "forced fun" trap at summer company parties?

The simplest answer is to give people choices.

The summer parties people enjoy most are the ones where participation feels optional rather than expected. Not everyone wants to be at the centre of the action, so we design events with a mix of experiences, from high-energy entertainment and activities to quieter spaces for conversation, food and relaxation.

We also brief hosts, performers and entertainers to read the room rather than put guests on the spot. A great summer party invites people to take part in their own way. It never makes them feel they have to.

Can you plan a corporate summer party across multiple UK offices?

Yes. We regularly deliver corporate summer parties across multiple locations, including simultaneous events in different UK offices, hub-and-spoke celebrations and coordinated summer events for organisations with teams spread across the UK and Europe.

The key is creating a consistent experience while allowing each location to work around its own audience, venue and logistics. We manage the planning centrally, coordinating suppliers, timings, communications and event delivery across every site.

Our experience includes delivering coordinated summer celebrations across multiple locations, ensuring every team felt part of the same event while allowing each site to reflect its own audience and environment.

What's the difference between a corporate summer party and a company summer festival?

A corporate summer party is usually centred around a single guest experience, such as a garden party, barbecue, rooftop event, drinks reception or summer celebration designed to bring people together and make the most of the season.

A company summer festival is typically larger and more immersive, combining multiple entertainment zones, food experiences, activities and branded elements across a full day or evening. Festivals often work particularly well for audiences of 300+ guests, milestone celebrations and major company-wide events.

If you’re considering a festival-style format with staging, entertainment zones and large-scale production, explore our dedicated Corporate Festivals service. If your focus is a seasonal employee celebration, team event or summer social, a corporate summer party is often the better fit.

Are MGN Events the right events agency for our corporate summer party?

We’re usually the right fit for organisations planning a corporate summer party for 200 to 1,000+ guests, with budgets starting from around £50,000 and a desire to create something more distinctive than a standard venue-and-catering package.

Our clients typically come to us when they want a summer party that feels creative, well considered and professionally delivered, whether that’s a rooftop celebration, family-inclusive event or large-scale employee gathering.

We’re probably not the right fit if you’re looking for venue finding alone or working with very lean per-head budgets. But if you’re looking for a creative partner to design and deliver a summer party people will genuinely remember, we’d love to talk.
