How Much Does a Smart Home Cost in the UK in 2026?

How long is a piece of string?

That's normally my slightly unhelpful first answer when somebody asks me how much a smart home costs.

The reason is simple. No two smart homes are really the same.

One client might absolutely love music and want great audio throughout the house. Another might care far more about incredible lighting. Someone else wants everything brought together: lighting, heating, blinds, TVs, music, security, gates and cameras, all working as one home.

So rather than giving you a fairly meaningless figure of £30,000, £50,000 or £150,000, we've approached this differently.

We've built a Smart Home Cost Calculator that lets you work through the property and build an indicative technology budget based on what you actually want.

If you have architectural or electrical drawings, get them out before you start.

When the calculator asks how many rooms you'd like music in, work through the plans and count them. Do the same with TVs, motorised blinds, cameras and the other systems you're considering.

You don't need to know exactly what equipment you want.

That's our job.

You just need to think about how you'd actually like to live in the house.

The calculator gives you an estimated low-to-high budget rather than pretending it can produce an exact quotation online.

That's deliberate.

A smart home is bespoke, and the final price will always depend on the property, specification, finishes and equipment selected.

But it should give you something incredibly useful at the early design stage:

an idea of where your technology budget actually needs to go.

First things first: you can't build a smart home without the infrastructure

This is probably one of the least exciting things we'll ever sell you.

Cable.

Miles of the stuff.

CAT6, speaker cable, control cable, fibre and all the infrastructure that eventually disappears behind plasterboard, ceilings and joinery.

You don't see it.

You don't particularly appreciate it.

But it's absolutely fundamental.

Think of it like the wiring loom in a supercar.

Nobody walks into a showroom, opens the bonnet and gets excited about the wiring loom. But remove it and that very expensive car isn't going anywhere.

A properly pre-wired smart home can now run into tens of thousands of pounds at first fix, particularly as the cost of copper, fibre and labour has increased.

And this leads to something we've said for years:

The most expensive cable is the one you don't install.

Running a cable while a property is at first fix is relatively straightforward.

Deciding two years later that you'd like an outdoor television, a cinema in the attic, speakers in the garden or better connectivity at the gatehouse is another matter entirely.

Now we're potentially opening finished ceilings, disturbing decoration, working around bespoke joinery or digging up a beautifully landscaped driveway.

That £100 cable suddenly becomes a much more expensive exercise.

We can't anticipate every mad-cap idea somebody might have five years into owning a house.

Nobody can.

What good design can do is make sure we've got enough infrastructure in enough sensible places that, most of the time, we can find a way of doing it without ripping the house apart.

Long driveways, gates and detached gatehouses are a classic example.

Getting infrastructure out there during construction can look like an easy place to save money.

Until you need it later.

Then it has a habit of biting you in the bum.

Next comes the network

If somebody tells us they have a £100,000 technology budget but want to save money on the network, we're going to have a conversation.

Modern homes depend on connectivity.

Streaming TV.

Music.

Phones.

Tablets.

Working from home.

Security cameras.

Door entry.

Lighting systems.

Heating controls.

Smart appliances.

And probably three times as many connected devices once your kids get involved.

A good wired backbone and properly designed Wi-Fi network isn't really the glamorous part of a smart home.

But your family and your working life will thank you for getting it right.

A smart home is only as reliable as the network it runs on.

---

Is smart home technology a luxury?

Yes.

I don't think there's anything wrong with saying that.

It is a luxury.

But what has changed massively over the last 20 years is accessibility.

When I started in this industry, some of the things we're talking about genuinely were reserved for an incredibly small group of people.

That's no longer the case.

Take lighting as a simple example.

We're not an installer of Philips Hue systems, but Hue can achieve some of the basic things that a far more sophisticated lighting-control system does.

Lights can dim.

Scenes can change.

You can control them from an app.

The difference as you move further up the market is in the experience.

The reliability.

The integration.

The tactile quality of the keypads.

How the lighting has been designed.

How naturally the house responds.

And ultimately how little you have to think about the technology.

That's where professional smart-home design starts becoming something very different from simply owning lots of smart products.

How much should I spend on smart-home wiring?

There is no perfect price-per-square-foot figure, but it is a very useful way of establishing an early budget.

For example, our budgeting tool uses different allowances depending on whether you're looking for fairly basic infrastructure, a properly automated home or a much more comprehensive future-ready technology package.

It's not supposed to replace a detailed design.

It's supposed to condition the budget.

Because discovering during first fix that the technology package is going to cost substantially more than you expected isn't particularly useful to anybody.

Architects, interior designers, contractors and homeowners all need a sensible number to work with early enough in the process.

Once the drawings are developed, we can then move away from square-foot allowances and start designing the house properly, room by room and system by system.

---

What should I spend money on first?

If your budget is limited, my answer is pretty simple.

Cable it properly.

Then build a great network and Wi-Fi backbone.

After that, ask yourself a much more interesting question:

What actually brings you joy?

It's your house, not mine.

If sitting down on a Friday night with Netflix on a huge television and a great surround-sound system is your thing, spend money there.

If you have music playing from the second you walk through the door until you go to bed, invest in multi-room audio.

If architecture, interiors and lighting are what make you happy, put more of the budget into lighting design and control.

There isn't a correct answer.

A good technology designer shouldn't be trying to sell you every feature available.

They should be working out which parts will genuinely make the house better for you.

At the same time, there are some fantastic tricks that integrated homes can offer that clients simply don't know are possible.

That's where working with an experienced company matters.

Part of our job is listening.

The other part is saying:

"Have you thought about doing this?"

---

When should a smart-home company get involved?

Ideally?

At design stage.

When the architectural plans exist and there is still time to influence electrical layouts, lighting, joinery, plant rooms, blinds, networking and cable routes.

Unfortunately, that's not always what happens.

Quite often somebody suddenly says:

"Shit. What about the TVs and the lighting?"

And everyone starts running around trying to get a technology design turned around before the electrician closes the walls.

We can do it.

We've done it plenty of times.

But earlier is better.

Smart-home design should be part of the building design, not something bolted onto it at the end.

How can a smart home cost £100,000?

This is probably where people get hung up on the equipment.

But equipment doesn't make a good smart home.

A good designer attached to a great business does.

We've seen technology budgets well beyond £1 million where the client simply wanted the very best throughout the property.

At that level the numbers can become extraordinary.

But exactly the same principle applies whether you're spending £30,000 or £1 million.

The goal isn't to fill the house with equipment.

It's to design the right experience.

We work with a lot of different manufacturers precisely because we don't believe one brand is the correct answer for every property.

The product shouldn't be chosen because it's the easiest thing for the installer to sell or because it provides the best margin.

It should be chosen because it gives the client the right result.

That's also why our calculator isn't branded around one particular smart-home manufacturer.

At the budgeting stage, we're trying to establish what the house needs to do, not decide which logo needs to be on the box.

Smart lighting, audio, TVs, blinds and cinema all change the budget

This is where smart-home pricing quickly becomes impossible to summarise with one number.

A homeowner who wants conventional lighting, three televisions and music in the kitchen has a very different brief from somebody wanting:

• whole-home lighting control

• architectural keypads

• 15 zones of audio

• motorised curtains throughout

• a dedicated cinema

• CCTV

• gates and intercom

• heating and air-conditioning integration

• high-performance Wi-Fi

• centralised equipment

• whole-home control

The houses could even be exactly the same size.

The technology budgets wouldn't be remotely similar.

That's why the calculator asks about the individual systems rather than simply asking for the value or size of your home.

---

Can I install some of the smart home later?

Absolutely.

In fact, this is one of the most important parts of planning a technology budget.

You might not want twelve zones of audio today.

You might not build the cinema for another three years.

Maybe the garden landscaping isn't happening until phase two.

That's fine.

Just design for it now.

Put the infrastructure in.

Allow rack space.

Provide network capacity.

Run the cable.

Think about blind power.

Think about the garden.

Think about the attic.

Think about the gate.

Then spend the rest of the money when it makes sense.

Televisions get better.

Audio equipment changes.

Technology evolves.

The cable buried behind your finished walls is considerably harder to change.

---

So, how much does a smart home actually cost?

There genuinely isn't one answer.

And I'd be suspicious of anybody trying to give you one without understanding the property.

What we can do is help you establish a sensible budget.

That's what our calculator is designed to do.

Sit down with your plans.

Work through the rooms.

Think about the systems you'd actually use.

Try the options.

You might discover the budget is less than you expected.

It might be considerably more.

Neither result is necessarily bad.

The useful outcome is:

"Now I understand where I need to allocate my budget."

That's the point of the exercise.

And if the number doesn't work, change the specification.

Protect the infrastructure.

Prioritise what matters.

Phase what can wait.

A smart home should be designed around the people living in it, not around a shopping list of technology.
