Factors That Affect the Price of a Nest Installation

Wiring Needed

It can cost a little more if new wiring is required.

That depends on if you already have a wired thermostat or if you are happy to have your nest on a stand and plugged into a wall socket.

Existing Heating System

The installation can be less or more complicated based on the heating system already installed.

Old heating systems may have unlabelled and undocumented wiring which may be time-consuming for the installer.

Some places have the boiler in very inaccessible areas where working could be tricky.

If you are able to tell your contractor the make or model or send photos, then they can price a more accurate quote.


Prices in the south of the country are more expensive than in the north. In London and surrounding areas, expect to pay extra labour costs.

If the contractor needs to travel further than usual to reach your place then they may also charge extra.

What is a Nest Thermostat?

A Nest Thermostat is an easy to install smart thermostat from Google. Unlike standard home thermostats that require the homeowner to adjust the temperature continually or when the central heating kicks in, the Nest thermostat has an intelligent learning feature that learns the temperature you like and the time you want and even how your home heats and cools itself.

The Nest Thermostat automatically creates a schedule after a week of everyday use for you and heats your home to your optimal temperature without human intervention.

Other features of the Nest Thermostat include a home/away assist feature that automatically controls the temperature after you’ve left the house. If you’re away from home for a period of time, you will turn off your hot water tank until you return.

Safety is a critical component of the Nest Thermostat. Boilers are a common source of dangerous carbon monoxide leaks. When Nest Protect detects CO gas, it will instruct the thermostat to shut the boiler down.

Convenience is also at the very root of the Nest Thermostat. It can be controlled by remote control, smart mobile phone or tablet, laptop, or integrated with Google’s Alexa assistant. In addition, it connects to your boiler via its dedicated radio frequency, meaning that if you suffer a power outage or wi-fi failure, your boiler will continue to give you hot water and heating.

Nest Thermostat Installation Process

While the installation process for Nest Thermostats is quite simple in most cases, it does need to be installed by a certified electrical contractor.

They will make sure it’s set up in the right location, connect it to the power supply of your heating system, and set the system up.

The contractor will switch off the mains power before starting the installation and help you choose where to place the Heat Link, which takes instructions from the thermostat.

It should be located somewhere away from large metal objects that may block the radio signal from the thermostat to the boiler.

They will then connect the neutral and live wires to the heat link and produce a circuit that matches your heating system. Once the other end of the wire is connected to the boiler’s power supply, the heating system can be turned back on.

A blue light at the top of the Heat Link means it is trying to connect to the Nest; a green light indicates that the connection has been achieved.

When installing the thermostat, it’s vital to pick a room where you spend most of your time, such as an office, the living room, or the kitchen.

Plug the Nest in and stand it on a surface if you don’t want it attached to the wall. However, it must be within 2 metres of a power outlet as it must always be plugged in.

The Micro-USB cable will connect to the socket in the rim of the Nest’s base and be plugged into the power supply.

This base can be attached to the wall with screws if you want your thermostat to be wall-based, and the Nest is mounted on the base.

All that’s left to do then is to set up your Nest account online or via the Nest mobile app. Connect the Nest to your wi-fi network, perform any software updates and confirm that the Heat Link is connected to the thermostat, boiler and hot water tank.

You can then use the app to add the thermostat to your Nest account and begin to control the heating on the go.

Nest Thermostats vs Hive Thermostats

Until recently, Nest was the clear leader in the smart thermostat market. British Gas’ smart thermostat, Hive, has provided Nest with stiff competition.

At first glance, there are several similarities between the two systems. They are both controlled via smartphone, tablet or laptop and allow homeowners to control temperature and hot water and have holiday modes for when they’re not home.

Both systems also have a GPS feature that will track your location so that when you leave home, it will shut off the heating and, conversely, turn it back on again when you’re nearby.

Nest thermostats have a clear advantage over Hive, however, with their intelligent learning ability and built-in motion sensors to detect when you’re at home. This saves money by not heating an empty house.

In addition, Nest is compatible with a greater number of boiler types than Hive, and they can control the temperature of hot water with OpenTherm technology. In contrast, Hive can only switch hot water on and off.

Finally, although the two systems are relatively similarly priced, the Nest system comes with a 2-year warranty instead of the 1-year warranty offered by British Gas with Hive.
