Summer in London: making the most of this key business season

Summer can change the rhythm of a London business very quickly.

A stretch of warm weather, a run of big events and more people moving around the city can lift sales in a matter of days.

It can also expose weak spots just as fast – patchy rotas, slow suppliers, tired staff, unclear pricing or a shopfront that looks as though no-one's thought about it since February.

For London SMEs, the season matters because the city gets busier in different ways, all at once.

Tourists arrive, Londoners spend more time outside and major events pull crowds into particular neighbourhoods.

The businesses that do well in summer aren't always the ones with the best idea. Quite often, they're the ones that got organised early.

The businesses that nearly always benefit from summer

Some sectors get a seasonal lift almost by default.

Think food trucks in parks and at events, beer gardens, ice-cream vans, florists near outdoor venues, beachwear and sunglasses shops, juice bars, bike hire businesses, market traders and cafés with a strong takeaway offer.

If that sounds like your business, you won't see a lack of demand. But success might actually catch you out.

Stock and suppliers

Look hard at stock, prep time and how reliable your suppliers are.

If you sell products with obvious warm-weather spikes, build a short list of your summer bestsellers now and ask yourself three simple questions:

1. What runs out first?

2. What takes longest to replace?

3. What frustrates customers most when it's missing?

For an ice-cream van, that may be cones, napkins and chargers for a card machine. For a beer garden, it may be glassware, fridge space and weekend staff cover.

For a sunglasses shop, it may be the lower-priced styles that sell fastest when the weather suddenly turns.

Staffing

This needs similar attention. For many customer-facing businesses, holiday season lands right on top of busy trading.

Get annual leave requests in early, firm up rotas before the rush and make sure more than one person knows how to open, close, handle refunds and solve common problems.

If you need extra hands, don't wait until the first hot weekend to sort payroll and onboarding.

Good summer shifts disappear quickly in London. If you're bringing in temporary staff, make sure your pay processes are clear and keeping to the law from day one.

The physical set-up

If customers are likely to queue, where will they stand? If people are eating or drinking outside, is the space tidy, safe and easy to manage?

Rushing your outdoor set-up can create hassle for staff and give customers a poor impression. If you run a café, bar or restaurant, you may need a pavement licence if you want to put tables and chairs outside.

Government guidance says licences can cover removable furniture on the highway for food and drink businesses, with local authorities able to charge up to £500 for first applications and £350 for renewals.

Some boroughs also set their own local conditions, so it's worth checking early rather than assuming you can put seating out when the sun appears.

Some real-life examples

• A gelato shop could create a "fast queue" menu for its top six items, cutting decision time at the till.

• A popup drinks business trading at markets could pack a heatwave kit with extra ice storage, sunscreen for staff and back-up payment devices.

• A neighbourhood café with outdoor space could train one team member each shift to manage outside tables properly, so service doesn't become muddled between indoor and outdoor customers.

The businesses that could benefit from summer, with a bit more effort

Then there's the middle group. These are businesses that aren't obvious summer winners, but could still use the season well if they give people a reason to notice them.

This might be:

• A bakery.

• A bookshop.

• A salon.

• A florist.

• An independent retailer.

• A service business on a local high street.

Summer may not automatically bring customers through the door, but it does create openings.

Your offer

Ask yourself what changes in your customers' lives during summer.

They may be walking more, hosting more, going away, entertaining children, attending weddings, working different hours or spending more time locally at weekends.

Your product or service doesn't need to become something completely new – it may just need a seasonal angle.

For hospitality and retail, presentation matters more in summer because people are more likely to be passing, browsing and deciding on impulse.

Refresh your windows, your signage and your social media graphics. A business that still looks winter-grey in July is making life harder for itself.

Capitalising on other activity

It's also worth tying activity to what's happening nearby.

London's summer calendar is packed, and customers often plan loosely around events, travel and good weather.

You don't need to force yourself into every big city moment, but you should know what's going on in your patch.

• A restaurant near Hyde Park should be thinking about concert nights.

• A café near a station should think about takeaway breakfast and cold drinks for people heading to events.

• A gift shop near a museum or visitor area should look at products travellers can carry home easily.

Local digital marketing

Don't ignore it! Update your Google Business Profile, make sure opening hours are right and post timely photos.

If you use LinkedIn or other social channels, keep it simple and real. Grow London Local's LinkedIn guide explains how consistency matters more than posting every day, and content works best when it feels rooted in the real business and local context.

If your customers are more likely to find you through short-form content, it's worth exploring Grow London Local's guides to TikTok and Instagram too.

Both are full of practical ideas for showing what your business is like day to day, sharing products or services in a natural way and staying visible without making social media a full-time job.

Some real-life examples

• A bookshop could build "holiday read" bundles, host an evening event with an author or put together children's activity packs for school holidays.

• A florist could sell small table arrangements for garden parties, weddings and summer dinners rather than focusing only on large bouquets.

• A salon could promote practical summer services such as holiday-ready appointments, quick treatments for people heading away or weekday packages aimed at quieter daytime slots.

• A bakery or deli could add picnic boxes, office lunch bundles for nearby parks or pre-order platters for sports screenings and local events.

The businesses likely to have a slower summer

Some businesses slow down in summer almost every year.

That can happen because clients are away, projects pause, decision-makers disappear or customer habits shift until September.

For some B2B firms, consultants, education-linked businesses and office-based services, that quieter spell can feel frustrating. But it can also be useful, if you treat it properly.

Honest analysis

The first job is honesty. If you know August is usually soft, don't spend June pretending it'll somehow be different.

Plan cash flow early, trim unnecessary costs and decide what a good "quiet season" would actually look like for you.

This is often the best window for work that gets neglected when business is busy. That might include:

• Reviewing pricing and margins.

• Fixing operational problems that waste time.

• Refreshing your website copy.

• Batch-creating social posts for autumn.

• Producing stock ahead of busier periods.

• Taking proper leave before the next push begins.

Staff training and wellbeing

And there's a people side to this as well. If your team has been running hard for months, summer can be the right moment to reset.

That doesn't mean drifting through a quiet patch and calling it strategy. It means using the space well. Upskilling, improving processes and taking proper rest all have a place here.

Some real-life examples

• A product business might use slower weeks to build inventory for Christmas or autumn launches.

• A small agency might document internal processes so work is easier to delegate later.

• A founder-led service business could spend time on business development that they never manage to do during peak months.

  That could mean following up old leads, improving LinkedIn profiles, asking for testimonials or setting meetings for September while diaries are still light.

A sensible summer plan for any London SME

Whatever kind of business you run, a summer plan just needs to cover the basics.

• Look at your likely trading pattern.

• Check staffing and holiday cover.

• Review stock, suppliers and lead times.

• Refresh the customer-facing bits of the business.

• Make sure your online information is current.

Think about local events, local footfall and whether your offer needs a seasonal tweak. If you expect summer to be slower, decide now how you'll use that time on purpose.

Then, when autumn comes, review what actually happened. Which weeks were busiest? Which products moved? Which campaigns worked? Which staffing headaches kept coming back?

A short debrief in September will make the following summer much easier.
