Loxone vs Crestron: Which Is Right for a UK Home?

Crestron has been the reference name in high-end control since long before “smart home” was a phrase. If you’ve been in a boardroom where one button dimmed the lights, dropped a screen and dialled a video call, that was probably Crestron.

The question isn’t whether it’s good. It’s whether what makes it good is what your house needs.

Different origins, different strengths

Crestron came from professional AV and commercial control. Its heritage is video distribution, matrix switching, conference rooms and bespoke touch-panel interfaces. That lineage shows in the quality of the hardware and in the price.

Loxone came from building automation. Its heritage is lighting, heating, shading and energy — the systems that run continuously in the background rather than the ones you sit down in front of.

Both have since expanded into the other’s territory. Neither has fully caught up.

Head to head

Where Crestron is worth the money

Serious AV. Multi-source video distributed to many rooms, a dedicated cinema with complex signal chains, integration with professional audio. Nothing in the automation-led world matches it.

Bespoke interfaces. If you want a touch panel designed precisely to your specification, with your own graphics and layouts, Crestron does that properly. Loxone gives you a good, consistent app — but it’s their app.

Very large properties. At estate scale, with dozens of zones and multiple buildings, Crestron’s commercial heritage tells.

Where budget genuinely isn’t the constraint. If the difference between £45,000 and £120,000 doesn’t change the decision, Crestron gives you more headroom.

Where Loxone is the better buy

Cost, by a wide margin. For lighting, heating, blinds, audio and energy in a normal large house, Loxone does it for a fraction of the price. Not a slightly lower price — often a third.

Automation as standard. Presence-based lighting, weather-compensated heating, sun-tracking blinds: enabled rather than programmed. In Crestron, much of this is bespoke code, and bespoke code is billed by the hour, now and every time you change it.

Energy management. Solar diversion, EV scheduling and circuit monitoring are core features. This is genuinely where the gap is widest.

Changes later. Adjusting a Loxone system is quick. Changing bespoke Crestron programming means the dealer, a scope and an invoice — which is why plenty of Crestron systems sit frozen in their original configuration for years.

The lock-in question

Worth understanding clearly, because it’s the most common complaint we hear from people who’ve inherited a Crestron system.

Crestron programming is bespoke to your project. Whoever wrote it holds the source files. If you don’t get those files at handover, moving to another dealer can mean substantial reprogramming rather than a simple transfer — and some owners find themselves effectively unable to change anything.

If you go Crestron, put the source programme files in the contract. It’s a reasonable request and a serious problem to discover you don’t have them.

Loxone is more portable — any Loxone partner can open the configuration — but the same principle applies. Get the project file and administrative access in writing, whatever you choose.

Our recommendation

Crestron if the project is AV-led, the property is very large, you want fully bespoke interfaces, and budget isn’t the deciding factor.

Loxone if the project is automation-led, you care about energy, and you’d rather spend £45,000 well than £120,000 on capability you won’t use.

For most large UK homes — even substantial ones — the honest answer is that Crestron is more system than the brief requires, and the difference buys a lot of other things. But if you’re building something where the AV genuinely is the point, we’d tell you to talk to a good Crestron dealer rather than pretend otherwise.
