As I write this in the middle of July, a large part of Britain is hot, tired and thoroughly fed up.

And the less said about England’s exit from the World Cup the better! ;-(

People are trying to sleep in bedrooms that still feel like ovens at midnight.

They’re moving fans from one room to another… opening windows… closing curtains… opening the windows again… and wondering whether they should finally invest in portable air conditioning.

Outside, it is much the same story…

Flowerbeds are wilting.

Hanging baskets need watering constantly.

Once-green lawns have turned brown and brittle.

People who previously regarded prolonged extreme heat as something that happened in Spain, southern France or Greece are starting to accept an uncomfortable truth:

What If This Is Something We Need To Prepare For Every Year?

Now, before I go any further, I should stress that what follows is really a collection of my initial notes.

This is a mini Mega Trend Alert rather than one of my full reports.

The changing climate is going to create opportunities across almost every conceivable market: food production, farming, construction, insurance, energy, clothing, travel, health, workplace design, transport, water management and many others.

The UK Government has just published research estimating that climate adaptation could represent a £154 billion to £355 billion market opportunity for UK businesses over the ten years from 2026 to 2035.

Globally, it estimates that around £3.5 trillion could be spent adapting to physical climate risks over the same period.

That is a vast subject.

I will be digging much more deeply into it and developing these early ideas into a larger report.

For today, however, I want to concentrate on one relatively accessible corner of the trend:

Information and products that help ordinary householders adapt their homes and gardens to hotter, drier and more unpredictable weather.

These are opportunities that someone could potentially pursue from home through:

• An email newsletter or Substack publication
• Digital information products
• Affiliate marketing
• An Amazon business
• A Shopify store
• Carefully chosen white-label products
• Sponsorship and advertising
• Or some combination of the above

And while the current heat may already have created a stampede for fans and air conditioners, I believe the larger and more sustainable opportunity is only just starting to emerge.

Why The Summer Of 2026 Feels Different

Britain has had memorable hot summers before.

Those of a certain age still talk about 1976.

We had the record-breaking 40°C heat of 2022.

The summer of 2025 was exceptionally warm.

But there is something about 2026 that feels different.

The heat began remarkably early.

Western Europe experienced an intense heatwave during the second half of May, with parts of England, Wales and western France recording daily average temperatures more than 10°C above the seasonal norm.

June then became the warmest June on record for western Europe. England recorded its warmest June since records began, with exceptionally high overnight temperatures as well as high daytime temperatures.

By July, many areas of Britain were experiencing their third heatwave of the year.

For the first time in the UK’s weather record, temperatures of 35°C or higher had been recorded during May, June and July of the same year.

Britain is far from alone…

Much of western and central Europe has experienced the same pattern, while the United States has also seen exceptional heat during 2026. March was the warmest March recorded across the contiguous US in a temperature record going back to 1895.

No single hot day or isolated heatwave proves anything by itself.

But when record temperatures keep arriving earlier… lasting longer… and affecting large parts of Europe and North America at the same time…

People begin to recognise that something fundamental may be changing.

More importantly from a business perspective: people begin changing their behaviour.

A Problem Becomes Real When You Feel It

Most people don’t change how they live because they have studied a climate graph.

They change when a problem arrives in their bedroom, sitting room or back garden.

Climate change can feel abstract when it is presented as a forecast of what may happen by 2050.

It becomes painfully real when

• You cannot sleep because your bedroom is still unbearably hot at one o’clock in the morning.
• An elderly parent cannot get comfortable.
• Your dog spends the day panting on the kitchen floor.
• The loft conversion you spent thousands of pounds creating becomes unusable for weeks at a time.
• Plants you have spent years nurturing begin to wilt.
• You have to water your pots and hanging baskets twice a day merely to keep them alive.
• You decide you finally need a decent fan, only to discover that everyone else has had exactly the same idea.

That deep psychological and societal shift matters.

Once people have experienced a painful problem, they start looking for ways to prevent it happening again.

We Can Already See A Change In Buying Decisions

During one of the recent hot weekends, Currys reported that sales of fans increased by nearly 3,000% compared with the previous weekend.

Sales of air-conditioning units rose by approximately 330%.

Supplies became tight because demand rose so rapidly.

UK shoppers also moved more of their spending online during June. Online non-food sales increased while physical store sales declined, with heat-related purchases including fans and paddling pools helping to drive demand.

This is what a new market often looks like in its early stages.

It doesn’t necessarily begin with people calmly deciding to embrace a new lifestyle.

It begins with discomfort.

They can’t sleep.

Their home is too hot.

Their children are complaining.

Their garden is suffering.

The product they suddenly want is out of stock.

Pain turns a vague concern into an urgent buying decision.

But I don’t think the real opportunity is simply to sell more fans.

Fans are merely the most obvious and immediate expression of a much wider change.

The larger opportunity lies in helping people prepare their homes and gardens for a type of weather they increasingly expect to experience again.

The Problem With Chasing A Heatwave

There is one rather large catch.

By the time everyone feels the pain, it may already be too late to build an income around it.

Here we are in the middle of July 2026.

You could certainly create a quick article comparing fans or portable air conditioners and earn some affiliate commission.

You could publish advice on cooling a bedroom or saving a wilting garden.

You might even find a simple cooling product they could sell through Shopify.

But realistically, it is now too late to:

• Research and develop a strong white-label product range
• Find and thoroughly check reliable suppliers
• Import stock
• Build convincing Amazon listings
• Accumulate customer reviews
• Develop substantial search visibility
• Build a trusted audience
• Create genuinely authoritative information products
• Establish relationships with sponsors and advertisers

There is also a considerable danger in ordering large quantities of seasonal products while temperatures are at their highest.

As we all know, the British weather can change remarkably quickly.

A run of cooler, wetter weeks could leave a would-be entrepreneur with a garage full of cooling towels, sunshades and plant-watering devices until next year.

So I am not suggesting that you rush out and attempt to cash in on the current heat.

That would be chasing the market after it has already taken off.

The smarter play is to study what has happened… identify the questions people are asking… understand what they are buying… and prepare for the next stage of the trend.

Remember How This Summer Felt

The real commercial value of summer 2026 may emerge after the temperature begins to fall.

People will remember:

• The nights they could not sleep
• The rooms that became unusable
• The constant noise of fans
• The elderly relatives they worried about
• The plants they lost
• The brown lawn
• The daily watering
• The hosepipe restrictions
• The cooling products that sold out
• The feeling that their home and garden were completely unprepared

That experience will not simply disappear when autumn arrives.

In fact it opens up new opportunities you can start developing right now.

Opportunity #1:
Keeping British Homes Cool

A great many British homes are extremely good at retaining warmth.

That has traditionally been considered a benefit.

For much of the year, it still is.

But it becomes a serious problem when several days of high temperatures cause heat to build up inside the property.

Bedrooms, loft conversions, conservatories, flats and south-facing rooms can become especially uncomfortable.

In London alone, recent analysis suggests that around one million homes may be at high risk of overheating.

This creates a huge demand for practical, trustworthy information.

People will increasingly seek answers to questions such as:

• How can I keep my bedroom cool at night?
• Should I keep the windows open or closed during the day?
• Where should I position a fan?
• Are expensive tower fans really better?
• Does reflective window film work?
• Which blinds block the most heat?
• How can I cool a loft conversion?
• How can I stop my conservatory overheating?
• Is a portable air conditioner worth buying?
• What does air conditioning cost to run?
• How can I cool a rented flat without making permanent changes?
• Which products are safe for an elderly person’s bedroom?
• How can I keep my pets comfortable?

These questions could support an entire specialist newsletter or information website.

Possible publication ideas might include:

The Climate-Ready Home

The Cool Home Report

Heatproof Your Home

The Cool Bedroom Guide

You could create product comparisons, downloadable guides, heatwave checklists and room-by-room cooling plans.

And you could earn affiliate commissions by recommending:

• Fans
• Air circulators
• Portable air conditioners
• Cooling bedding
• Mattress toppers
• Blackout and thermal blinds
• Window films
• Shade sails
• Awnings
• Indoor thermometers
• Smart plugs
• Pet cooling mats

You could also develop simple non-electrical white-label products.

I would avoid beginning with electrical equipment. Certification, warranties, safety problems and returns make that a much more demanding business.

Simpler opportunities might include:

• Cooling towels
• Reflective window coverings
• Thermal curtain liners
• Cooling pillowcases
• Reusable cooling packs
• Personal heatwave kits
• Bedroom temperature monitors
• Pet cooling accessories

The real value would come from combining products with excellent information.

Instead of placing a logo on another generic cooling towel, you might create a Cool Bedroom Kit supported by a detailed digital guide explaining how to prevent the room heating up in the first place.

That turns a commodity into a specific solution.

Opportunity #2:
The Climate-Ready British Garden

The garden market may ultimately prove even more attractive.

Cooling products tend to generate intense bursts of demand when the temperature rises.

Gardening is seasonal too, of course, but the problems created by a changing climate extend throughout the year.

Gardeners may face prolonged dry spells and intense heat during summer…

Followed by heavy rain, waterlogging and drainage problems during winter.

The RHS predicted before the start of 2026 that climate would become the main driver of activity in British gardens, with increased emphasis on planting diversity, water management and coping with changing weather.

That prediction now looks remarkably well timed.

There is also a powerful emotional element to this market.

A garden is rarely just a collection of plants.

It can represent years of time, effort and affection.

When someone sees a mature shrub wilting or a carefully planted border beginning to fail, they do not merely see damaged leaves.

They see something they have nurtured and invested in slipping away.

That creates an urgent demand for help.

During periods of intense heat, people will search for information such as:

• How can I save a badly wilted plant?
• Which plants should I water first?
• Is my brown lawn dead?
• How often should I water my garden?
• Is it better to water in the morning or evening?
• How can I protect hanging baskets?
• Can I safely use bathwater on plants?
• How do I stop vegetables from bolting?
• How can I shade vulnerable plants?
• How do I keep everything alive while I am away?
• What can I do during a hosepipe ban?

The RHS is already advising gardeners to water deeply rather than constantly, use mulch, collect rainwater and consider carefully managed greywater when stored rainwater runs out.

But the larger opportunity goes well beyond emergency advice.

After this summer, more gardeners will start asking:

• Which plants are best suited to hotter British summers?
• Should I replace some of my lawn?
• How can I store more rainwater?
• Can I create a garden that requires less watering?
• Which plants can cope with both summer drought and wet winters?
• How should I improve my soil?
• How can I create more shade?
• Are self-watering containers worthwhile?
• Which traditional British garden plants may struggle?
• What should I plant instead?

Those questions can generate content and product demand throughout the year.

Several Possible Garden Niches

The broad positioning could be:

The Climate-Ready British Garden

The promise would be to help people create an attractive garden capable of coping with heat, drought, heavy rain and unpredictable conditions.

That could lead to information products such as:

• The Climate-Ready Garden Handbook
• 100 Plants for Hotter British Summers
• The Month-by-Month Resilient Garden Planner
• How to Create a Drought-Tolerant Border
• The Brown Lawn Recovery Plan
• How to Save Your Garden During a Hosepipe Ban

Affiliate products could include water butts, irrigation systems, timers, soaker hoses, soil-moisture meters, mulch, shade cloth, raised beds, self-watering containers and drought-resistant seeds.

Another strong angle would be:

The Water-Wise Garden

This is commercially attractive because the appeal is not limited to people who are especially concerned about climate change.

It offers practical everyday benefits:

Less watering.

Lower water use.

Fewer lost plants.

Less work.

A garden that can survive while its owner is away.

Potential white-label products could include:

• Container watering kits
• Holiday watering systems
• Drip-irrigation starter kits
• Tree-watering bags
• Moisture-meter bundles
• Watering spikes
• Reusable mulch mats
• Rain gauges
• Garden planning journals

A particularly interesting sub-niche could be:

Climate-Ready Container Gardening

This would appeal to people with patios, balconies, courtyards and smaller gardens.

Containers dry out quickly in hot weather, so the problem is obvious and immediate.

A specialist publisher could cover self-watering pots, balcony irrigation, heat-tolerant plants, holiday watering and low-maintenance container displays.

One simple physical product might be a Seven-Day Holiday Watering Kit for Pots and Baskets.

That solves a problem that exists every summer, even when there is no official heatwave.

What About The Brown Lawn?

One of the most visible effects of the current weather is the transformation of green lawns into something resembling straw.

This will lead to a great many searches for lawn treatments, drought-resistant seed and recovery products.

But there is also an opportunity to help people understand what is actually happening.

Established lawns often turn brown and dormant during drought before recovering when rainfall returns. The RHS generally advises against attempting to keep an established lawn permanently green through heavy watering and points towards longer-term maintenance and alternatives such as clover, thyme and wildflowers.

That creates content around:

• Whether a brown lawn is dead or dormant
• How to restore a lawn in autumn
• When to reseed
• Drought-resistant grass varieties
• Reducing the size of a lawn
• Clover lawns
• Thyme lawns
• Gravel gardens
• Wildflower areas
• Lower-maintenance alternatives

Once again, the opportunity is not simply selling a bag of grass seed.

It is helping people make sense of a problem and choose the right response.

A Business That Follows The Seasons

The most promising model would not rely entirely on the few weeks when Britain is experiencing extreme heat.

It would follow the problems people encounter across the year.

During late summer and autumn, content could focus on garden recovery, lawn repair, soil improvement and drought-resistant autumn planting.

During autumn and winter, attention could shift towards rainwater collection, drainage, waterlogging and preparing the garden for more extreme conditions.

From February onwards, the business could begin promoting water butts, irrigation systems, shade products, climate-ready planting and home-cooling preparation.

During the first genuinely hot spell, it could switch into rapid-response mode with:

• Heatwave advice
• Emergency garden guidance
• Updated product comparisons
• Affiliate promotions
• Stock availability
• Cooling checklists
• Watering schedules

This gives the business an evergreen foundation while retaining the ability to capitalise on sudden weather-driven demand.

The Best Home-Based Business Model

Personally, I’d always begin with information.

That could mean a Substack publication, email newsletter or specialist content website.

Building an audience first would provide an opportunity to discover what people actually want before investing heavily in stock.

You could ask readers:

What was your biggest problem during the heatwave?

Which rooms became unbearable?

Which plants suffered most?

What did you try?

Which products worked?

Which products disappointed you?

What do you wish you had bought earlier?

Those answers could then guide the creation of:

• Digital guides
• Product comparisons
• Affiliate recommendations
• Sponsored content
• Own-brand kits
• Amazon products
• A specialist Shopify store

This is a much safer approach than guessing which products will be popular and ordering a container full of them.

It also creates a valuable competitive advantage.

Most Amazon sellers begin with a product and then try to find customers.

An information publisher can begin with the customers… understand their problems… and then create or source the products they are already asking for.

These are only my first notes

As I said at the beginning, this is more of a mini Mega Trend Alert.

I have concentrated mainly on homes and gardens because they provide some of the most accessible opportunities for a small, home-based operator.

But they represent only a fraction of what is likely to emerge.

Changing temperatures and weather patterns will affect what we eat, where food is produced, which crops can be grown, how buildings are designed, where people travel, what they wear, how they work, how they exercise and how they care for older relatives.

There will be new problems to solve, new subjects to publish about and entirely new categories of products.

Some ideas will prove too capital-intensive or technically demanding for the individual entrepreneur.

Others will be highly accessible through information publishing, affiliate marketing and relatively simple

physical products.

My aim in the larger report will be to separate the plausible home-based opportunities from the ideas that sound exciting but would be extremely difficult to execute.

For now, however, the central point is this:

The summer of 2026 has transformed extreme heat from an abstract forecast into an uncomfortable personal experience.

People have felt it inside their homes.

They have felt it in their bedrooms.

They have seen it in their gardens.

They have watched products disappear from the shelves.

And once people become painfully aware of a problem, they begin searching for ways to prevent it happening again.

It may be too late to build a serious business in time to benefit from the current heat.

But for someone prepared to start researching the market now, start publishing, build an audience and test the right products… it could pay off in a big way in 2027.
