Of all the services offering to take control of your heating, Hive is probably the system that has the highest profile. That's in no small part due to plenty of marketing and a brand name that's instantly recognisable: British Gas.

Hive Active Heating promises to cut your energy usage by dragging your heating system into the twenty-first century. It will give you controls that aren't lurking in a musty cupboard, instead making your smartphone a device that controls all.

We had Hive Active Heating installed in November 2013 and have been living with the new smart heating and hot water system since. Two years later, there's a updated Hive 2.0 thermostat, updated apps, and the start of the next chapter in Hive's smarthome conquest.

What is Hive Active Heating?

Hive is a system that's made up of several components, all interconnected, which is where we imagine British Gas found inspiration for the name. British Gas originally had a product called Active Heating, it then launched Hive by British Gas, and it is now known as Hive Active Heating.

There's a controller that replaces your existing central heating and hot water controls, most likely next to your boiler or hot water tank, there's a wall controller and thermostat, and finally the hub to attach it to the internet via your router.

That last part of the puzzle is needed because to fully control Hive you'll need to use either the website dashboard or the app on your smartphone. It's available on iOS and Android, although the web front-end means you can access it anywhere you have a browser.

The idea is to move away from manual switches and sliders, or controls that aren't intuitive because they're governed by a small display with a couple of buttons. In its place, comes control at any time, from any place, in a form that's simple and easy to use.

The actual functionality of your heating and hot water system will remain the same - more or less - but the control and programming of it will now be smart.

Hive Active Heating review: Installation

One of the important considerations of Hive is the "by British Gas" part. It makes Hive approachable, because the installation is carried out by British Gas, so you're not faced with buying components and then wondering who you'll get to install it.

The Hive Active Heating Kit will cost you £249, including the cost of installation, and it has stepped up slightly from the £199 price when we first looked at Hive in 2013. You can have it installed by other installers if you choose, and the kit will cost £179, with a choice of heating and hot water, or heating only if you have a combi boiler.

It doesn't mean your gas supply needs to come from British Gas, however, as you're paying the company for the components and the install, although there may be other special offers for British Gas customers that are worth keeping an eye on.

Installation is swift, but will ultimately depend on your system. As we installed it on a fairly new central heating system - previously installed by British Gas coincidentally - the actual process took less than an hour. It really was as simple as swapping one box for the other, hooking up to the router and getting all the parts talking to each other. An older system won't necessarily provide that ease but British Gas can advise on a case-by-case basis and this is part of what you're paying for.

When it comes to updated components, it's easy to switch these around yourself. We've updated the hub and added the Hive 2.0 thermostat and it's a very easy process to do yourself.

Hive Active Heating review: The new Hive 2.0 thermostat

There have been two different thermostats for the Hive. The latest takes a leap forward, replacing the rather pedestrian launch thermostat with a totally revised design by Yves Béhar, designed to compliment the rest of your smarthome. You can also be accessory frames, incase you want to change the colour for something more interesting than white.

With the likes of Nest offering a sophisticated thermostat, it's great that Hive has updated. The new design sees a return to a square format with a central dial. We love that retro styling and the feel of the dial reminds us of thermostats and dimmer switches of the past, with a tactile analogue feeling. It really does feel like you're cranking the heat up. 

That dial sits in a reflective faceplate that lies over a display. Much of the time it's blank, sitting innocuously in your house minding its own business. As soon as you interact with it, however, the details shine out from the depths. It's so much more sophisticated than the previous model and if you've got the option to upgrade, we'd recommend it, especially if you're house proud.

There are two buttons on the top and these will give you instant access to boost for hot water or heating. That will mean you can trigger either of these functions, setting the time you want that boost to last for.

On the face itself there are three buttons: back, menu and ok. The menu structure is simple, so you can easily put the heating on schedule or manual, you can turn the dial to increase or decrease the temperature, or you can engage holiday mode.

If we've one criticism, it's that the display behind the surface could have been a higher resolution. We're getting increasingly used to high-resolution smartphones and we instantly felt that things were a little blocky. Increasing the resolution would give smoother fonts to be more pleasing to the eye.

Hive Active Heating review: Heating and hot water control 

Hive does away with fiddly programmers. You can open up the Hive website and login and you'll be able to set the heating and hot water programme you want using easy sliders. Although the app offers the same controls, you get a lot more space on the website, so is probably the best for first setup.

It's easy to set the programme you want for each day, so you can select when you want heating or hot water on, for how long, decide what you want the house temperature to be for different periods and so on. You can have different heating periods across different days, with up to six slots a day. That gives real flexibility, if you need it, especially as you can make it different for different days of the week.

The same applies to hot water. If you know you need it on Sunday for a shower after coming home from football at 3pm, you can set it specifically for that. You can have the hot water coming on later on Saturday morning and if you're regularly away from home, turn it off completely for those days.

What Hive doesn't offer is individual room controls, this is a universal system that covers your whole house, although it now supports multiple zones, if you have the plumbing for it.

Hive Active Heating review: App control

The app has been through several revisions, adding new features since launch. The app is the main point of interaction with Hive. Although the new thermostat is easy to use, we've found it's often the case that you change it when you're sitting on the sofa, or when walking down the road using the app.

The advantage of having app control is that you can leave the house and still have control. If you are away and forget to turn the heating off, you can go in and change the programme to frost protection, for example.

You can put the hot water on boost if you're on your way home and suspect that you won't have the hot water and you want for a bath. You can be lying in bed on a lazy Sunday morning, well after the heating schedule has stopped, and opt to warm the house up again.

The app includes a geolocation feature that aims to offer the same sort of controls as Tado, where it will detect if you've left home and offer to turn the heating off. This feature is governed by the location of your phone, however, so we'd recommend that if you want to use the feature you increase the leaving trigger area from the default 700ft. If your device isn't certain of its location, we've sometimes found it suggesting that the heating is changed when we're still sitting at home.

Hive Active Heating review: Holiday Mode

A recent addition to Hive's skills is Holiday Mode. This can be accessed through the new thermostat, app and website.

In Holiday Mode you get to set the dates that you're going to be away, setting your departure and return times through a calendar view. You can then set the temperature you want the house to remain at while your away. That might be to protect pipes against freezing, or just to keep your cat warm.

It's a nice addition and might be useful for those who tend to forget, but the big advantage of having a smart heating system is that you can control it from anywhere. More than once we've changed it on from a campsite in France, or the departure lounge of an airport.

Hive Active Heating review: Performance

We've been living with Hive for the last 2 years and we've enjoyed the control that it offers through smartphones. While many will see the advantages of being able to control the heating when you're away from home, in reality, it's in the home that we've used it the most - the heating boost on a cold winters evening.

Hive's pitch at launch was to reduce bills by making your heating more efficient. So the question is, have we seen savings over that 2-year period? In reality, it's difficult to judge, because it all depends on how efficiently you were using your heating system before. As we considered ourselves diligent thermostat watchers, we can't see much of a difference, but it's now a lot easier to control and we've spent less time scrabbling around in the airing cupboard.

With all wireless system you have to deal with connectivity. Anyone who uses lots of Wi-Fi devices will know this and Hive Active Heating is the same. There have been occasions where the system has stopped communicating, leaving us to pull the plug and reboot it all.

Hive works on the ZigBee wireless protocol (common for connected home devices), and if you're having connectivity problems then a ZigBee booster plug could solve these problems. We found that was the case with the first generation hardware. But having updated to the newer more powerful hub, incidences of inoperability have decreased.

Over the timeframe we've been using Hive we've seen the stability of the apps improve and with the latest thermostat, Hive feels like a more sophisticated system than it was at launch.


Hive Active Heating remains one of the more accessible smart heating systems. There are a growing number of rivals, but with British Gas pushing Hive, it's an easy option to select. The Hive universe is also set to expand, with support for zoned heating (which we haven't been able to test), and sensors and other smarthome devices in the future.

The latest iteration of Hive Active Heating is the most compelling so far. The refreshed thermostat gives a visual lift with a smarter retro design and offers much better functionality than the previous version.

The new features give you more flexibility for greater control, but the competition from the likes of Honeywell and Nest remains strong. There has been no word on Homekit compatibility, something you might want to clarify before you invest if you're an Apple user.

Overall, Hive Active Heating is great, offers a new thermostat that looks fantastic in this latest version and continues to strengthen its offering.
