Put yourself back in control!
Retrofitting a wireless thermostat should be an easy DIY task however we always recommend getting professional help to ensure the replacement is compatible with your boiler and available wiring.
Quite simply, they can reduce your energy consumption and save you money.
Having your heating and hot water on only when you need it makes perfect sense, but this isn't always the reality. With a standard thermostat the temperature can be set along with other basic functions but more often than not, the house is being kept lovely and warm when there's no-one at home!
With the advent of Wi-Fi controlled thermostats you not only have the advantage of multiple pre-programmable settings, but also have the ability to change them at any time, any where.

Before starting, turn off the power to the heating and cooling system at the main fuse box and at the boiler isolating switch. Check that the thermostat screen is off - many thermostats have battery back-ups, so ensure these are also removed. Do not turn the power back on until the installation is complete.
Ensuring the power is off, remove the front panel of the old thermostat to reveal the wall plate and wiring. The front will normally just clip off, but some have locating screws, so remove these if necessary.
Before disconnecting any wires, take a note of the terminal letters and the corresponding cable colours / labels. Better still, take a photo of the connectors for future reference. Some new thermostats are supplied with labelling stickers, if so, stick these on to the cables now using the corresponding letters on the terminal block. Remember, wire colour does not necessarily mean wire function.
Remove wires one at a time by loosening the terminal connectors with a screwdriver. Bend the wires carefully to ensure they do not fall back through the wall plate. Avoid the bare wires touching each other.
Once all wires are disconnected, unscrew the wall plate fixings and carefully remove the wall plate. Ensure the cables do not fall through in to the wall cavity – taping them to the wall or wrapping them in a bundle around a pen or pencil is a handy tip. To avoid the new thermostat being affected by drafts from the wall cavity, it's advisable to fill the hole around the cable entry point with a non-combustible insulation.
Check the condition of the bare end wires and, where required, clean off any corrosion and strip the cables to leave a 9-10mm of bare wire ready for re-connection. Lightly twisting the bare wire ends with your fingers will make the cables easier to insert in to the new terminal block.
Feed the cables through the new wall plate and hold it against the wall. Check if the old fixing holes align with the new wall plate, if they do not, mark and re-drill new fixing holes. Fill any old unused holes with the non-combustible insulation. Attach the new wall plate to the wall.
Re-attach the wires to the new thermostat following the manufactures instructions and using the labelled wires and photo as a guide. Ensure all bare wire ends are fully inserted in to the terminal block and are securely located.
Finally, fit the new thermostat front to the wall plate ensuring the newly attached cables are not causing an obstruction. Turn the power back on and follow the manufactures guidelines to set-up your new thermostat.
There are numerous types of thermostats available, such as wireless thermostats that require a sender unit to be wired to your boiler and are controlled by a wireless remote, multi-zone systems, remote radiator controls and new generation 'smart home' learning thermostats that actually automatically adapt to your lifestyle.
