Nest vs Hive: Which is the best smart thermostat?

Hive Active Heating 2

Nest vs Hive – What's the difference?

Nest and Hive are two of the most high-profile options for anyone thinking of making their home’s heating smarter.

While we've reviewed the the first generation Hive and 2nd-generation Nest, both companies have recently released new versions that add new features.

They still both cost a few hundred pounds to install and aim to make your home heating smarter and cheaper in the long run.

But which is the best for you? Here’s a closer look at the differences.

Who makes these systems?

Nest is owned by Google, while Hive is from UK energy provider British Gas. Hive is only available in the UK, so we’re mainly going to focus on how the two compare from a UK perspective.

The Nest system is growing its own ecosystem of first-party and third-party accessories – any device marketed as "Works with Nest" can hook into its connected home system. Philips Hue lights work with Nest, and Nest itself has a range of other connected devices, including Nest Protect – a smoke alarm – and a new security camera called Nest Cam.

Hive, meanwhile, has recently launched a range of devices and a new app to take advantage. Motion sensors, door and window sensors, smart plugs and smart lights are part of the first wave of Hive accessories, with more first- and (potentially) third-party ones coming soon.

What's new in the 3rd-generation Nest Learning Thermostat?

Nest recently started selling the 3rd generation Nest, which is pictured above. Its screen is 40% larger than the previous version, which Nest says lets you see what's on the screen from right across the room. The screen's also sharper than before.

Of greater import is the addition of hot water tank support in the UK and Europe, a feature lacking in previous versions.

What's new in Hive Active Heating 2?

The most recent Hive has received a significant facelift. It has a glossy, mirror-like finish and supports a variety of different style shells to fit your home's decor.

The core features remain the same, but the interface both on the thermostat and in the app are completely new. Compared to the old model, which was very basic compared to other modern smart thermostats, it's a huge leap forward.

Which is the most expensive?

Nest Learning Thermostat – £249 with installation (£199 without)

Hive Active Heating 2 – £249 with installation

Hive used to be cheaper, but Hive Active Heating 2 actually costs the same amount to buy and install now. Current Hive owners can get the 2nd-gen version for £99 for a limited period, though.

Nest is also available without installation for £199, though we’d caution against this unless you’re totally confident in what you’re doing. It pays to do a little research first, as there’s a lot of "this wire connects to that wire" to deal with.

Which is harder to install?

Both systems come with similar parts, including a network hub, the thermostat itself and a regulator that connects directly to the boiler. The complexity of the setup will really depend on your home and whether you choose a professional installer or not.

The one key difference is that the Nest thermostat requires mains power, whereas the Hive Active Heating 2 thermostat can be powered by four AA batteries.

This is a nice option that gives you a little more flexibility over where you place your thermostat.

Nest wins points here too, though, as you have the option to place it on a stand rather than on a wall, which might be more convenient. It also means you don’t have to run wires through walls unless you really want to – a regular mains plug will do the job.

How do you control these systems?

The new Hive system is a lot more attractive and modern looking than the old one, so Nest have as much of an advantage anymore.

Fundamentally, both offer similar options, as you can either control them using the thermostat or rely entirely on the apps.

Both let you set your own schedules, too, but Nest goes one step further in its focus on learning your patterns and adapting accordingly.

It does this using its presence sensor, something Hive doesn’t have, though Hive 2 will notify you if it thinks you’ve left the heating on when you’ve left the home.

Which boilers work with these systems?

Hive and Nest cannot really be 100% specific about every boiler they support – there are a whole lot of boilers out there – but there are decent guidelines to follow.

Hive says any working gas or LPG heating system is supported, as well as some electric boilers. It suggests calling them if you have an oil boiler to find out if your system is suitable. It can work with some underfloor systems, but not ones that rely on electricity.

Nest says its system works with the following:

  • Combi and condensing boilers
  • System and heat-only boilers
  • Hydronic underfloor systems
  • Air-source and ground-source heat pumps
  • Switched live systems
  • Low-voltage dry-contact systems

Generally, though, compatibility should be very similar between the two systems, as it all hinges on the one component that "talks to" the boiler. Hive calls it a Receiver, while Nest refers to it as a Heat Link. This is the one part that really needs a qualified engineer to install.

Hive Active Heating 2 15Hive's app will let you control the heating and its range of accessories

What can they do?

Nest’s biggest trick is the learning ability and sheer simplicity of its system and thermostat. Sensors in the thermostat detect when you’re home, and Nest turns the heating down when you’re out even if it’s during a scheduled "on" time. That’s why it’s called the Nest Learning Thermostat, as opposed to the Nest Does What It’s Told Thermostat.

Of course, this is somewhat reliant on where you place your thermostat and its sensor, but you can add more thermostats to your system. Multiple thermostats will combine their data to work out better when you’re really at home, and they can even create separate smart schedules if your heating is already organised in zones – it can’t create zones in homes that don’t have them, though.

Hive can’t match this learning element, as it lacks the sensor of Nest to detect when you’re home. But you can use geolocation in the app to achieve a similar effect, and Hive is expanding its ecosystem to include presence sensors that could do this job in future.

The recent updated Nest also removes one advantage Hive previously enjoyed – hot water support. Previous Nest systems couldn't control a separate hot water tank, but the 3rd generation Nest Learning Thermostat can. We won't know how well this works until we test the new version, but it's an important addition for many UK homes.

Both systems have a holiday mode as well, and Hive 2 now supports multi-zone homes in a similar way to Nest – the first version didn’t.

Do they work with other smart home tech?

Nest has its Works With Nest program that allows products to hook into the Nest system. Many of the supported products are US-only, so the appeal is limited right now, but there are a few notable ones, such as Philips Hue lights, Jawbone and Google Now, and the list is growing all the time.

Of course, Nest being part of Google means this ecosystem is bound to grow quite quickly, and there’s a range of other Nest products such as Nest Protect and Nest Cam to consider. If you're a keen Android user then Nest would seem like the way to go, particularly given its ecosystem is already well-supported.

Hive Active Heating 2 47The Hive Active Motion Sensor

Nest isn’t alone in creating its own ecosystem of products, though. Hive has recently launched smart plugs, window and door sensors, and motion sensors. It also plans to launch its own smart lights and cameras in future, and has hinted at plans to work with third parties.

Neither system is Apple HomeKit compliant yet, though Hive says it’s considering it. Unlike Hive, Nest works with popular "recipe" service IFTTT, though Hive plans to support similar functionality among its own Hive accessories.

Which is best?

We're still testing the two new versions of these products, so we're not in a position to make a definitive verdict just yet. But the 3rd-generation Nest does remove some of the reasons to consider the Hive ahead of it.

Hot water tank support is the biggest of these. If you'd previously ruled out Nest because it lacked this feature then it's time to reconsider it. The learning element of Nest is another major attraction, though Hive's approach has merits too.

The wider Works With Nest ecosystem probably swings things in Nest's favour at the moment, but that assumes they both do the core job as well as each other.

We'll soon see whether that's the case.

Issue is not if all these refinements will effectively be left on the "cutting room floor' so to speak because they will, nor is it that you should have a system that allows activation of the spare bedroom heating because you've an unexpected guest arriving at 3am (Honeywell control at over£1300?), or even that you want to check the partner is actually at home in bed alone while you're away on business.

The real goal is that of energy efficiency, something which not even the Hive will achieve while it fails to be referenced to outside air temperature. Most of us would be better served with a basic three/four zone programmer a couple of additional zone valves and crucially ensuring these much vaunted 90% capable boilers actually operated in a condensing mode for more then the first half an hour of operation.....

And that final point alone is crucial because while these condensing boilers we're all forced to currently specify can be very efficient, we fail to exploit their potential. They could be operated at a optimum setting that would ensure they modulate the heating flow temperature automatically as a function of the outdoor temperature.
For some of the boilers currently available this function is already built-in and simply requires a outside sensor at £15 to be installed and selection in the menu. For others that haven't this facility the manual selection of a flow temperature around 60C rather then the obligatory 80C will also ensure greater levels of efficiency indeed for the majority of the 'heating season this will be fine. ....So why is this function only rarely activated and not only better control but significantly better economy achieved..... ignorance I'm afraid....

In essence, we need to address the fundamentals before we waste our hard earned cash on trivia like the Hive...

This article is called 'Nest vs Hive: Which is the best smart thermostat?'. So I read it to find out, only to discover that "we haven’t reviewed the updated Hive system yet, so it would be premature to declare a winner".
Clickbait junk.

There is an error in your article, you state that Hive does not support geolocation, I have found that Hive does indeed supports geolocation at least on iPhone and iPad Hive app, I'm not sure about android, you can turn it on under the settings tab within the Hive app

The Hive 2 thermostat is only battery powered and cannot be "wired in" as your article suggests.


October 16, 2015, 11:40 pm

For me the decider was Nest supports Celsius and Fahrenheit whereas Hive does not. Shame new version 3 is not available in UK for forseeable future.

"This box plugs into your router – Nest comes with a similar wireless hub"

No another error, Nest is self contained, it signs into your home WiFi there is no external HUB.

Thanks – we've corrected this in the most recent update.

Really? So nest gives you freedom to choose F (or C) and hive does not? That's one 'up-vote' to nest

Hello all,

I recently sent the following to Nest for there advice. Can anyone indicate if they have had similar issues?


I am considering purchasing your nest 3rd gen system to control heating and hot water but I have heard something about your system which is currently preventing me from purchase.

I know someone who already has a nest thermostat (1st or 2nd gen, im not sure which) but they have reported that a firmware update to the device has increased the pre-heat (time to heat up the place from x to desired temperature) up time to an unreasonable level. it changed from somewhere from 1hr to 3hrs. Meaning that if the desired temperature was 20degC at 6am then the heating would come on at 3am not 5am. This means that the noise of the heating system woke them up.

Can you advise is this has been reverted and/or is configurable? If configurable. How?"

I have installed both Nest and Hive in several rental properties.
I have had trouble getting signals between the thermostat on the ground floor and the controller in the airing cupboard at the top of a 4 storey terrace house with concrete floors and brick walls. Hive has a repeater that solves the problem. HIVE wins, unless you can get cabling from the boiler (heat link) to the kitchen/lounge/hall where the thermostat lives. Not a problem in most average houses with timber frames.
The Hive thermostat only runs on batteries - a big negative in rental properties. Nest can be plugged in to a USB supply and sat on a shelf, or wired into the old thermostat position - except that the old thermostat is probably not in the right place. NEST wins.
If the Nest Protect detects smoke it tells the Nest Thermostat to shut down the heating system - in case that is the cause of the fire. And if you go away on holiday Nest notices that there is no movement in the house, and automatically switches to Away mode, because the thermostat and smoke detectors have movement sensors. Very sensible. Nest wins.
Nest is organised much better for the owner to share access with guests (tenants) to use the app and remote control features. Once an account has been setup by the landlord with multiple Nests, a tenant can be invited to setup their own account with access to one of the Nests. BG has just informed me that they have changed their policy to require every new Hive account holder to pay £80 for a new hub - what a brain dead idea! They say that the Hive hub has no ability to be reset to wipe its stored confidential data, so BG's solution is that the outgoing tenant should take the Hive hub with them and the incoming tenant should spend £80 to buy their own Hive hub. That has to take the prize for bureaucratic stupidity. Nest wins again!

On balance, I am avoiding Hive in future and just going with Nest.

Article on nest vs hive ends in we don't know which is best. Awesome.

Let's face it, the idea these things will save you money is only if you are an idiot who keeps the central heating/hot water on all day every day and you can't remember or are too lazy to turn it off. If you are a "normal" person and you have your heating on timers or you turn it on and off as you need to then neither of these things will save you a penny. And even if they did, it would be a long time until they paid for themselves.

I had Hive, and it was crap. Frequent service problems, app not working, website not working. Although from what I read there were significant issues with Nest as well.. software updates that drained the batteries and stopped it from working etc.

I think if you want to have a device that works with a lot of other devices, get nest. If you want something shiny and nice to look at get nest. Otherwise get Hive. They both do pretty much the same job.. Hive is slightly easier to fit if you have the standard UK programmer you can just yank it off the bracket and stick the new one on top, whereas nest requires much more complicated install faffing about with wires.

I have a few questions. I am renting a flat at the moment and the gas & electric is with British Gas. I do like the idea of the nest system more as I am more Android orientated and this has apps which function with my smartwatch etc

First question would be, during installation what type of work needs carried out, is this something I would need permission from a landlord first and if I moved out how easy is it to uninstall back to the old system.

Second question being with British Gas would the nest system still be compatible?
