Who Can Install tado°? Gas Safe, Electrician or DIY

• The regulations exclude work on a control device meant for the consumer, as long as it does not involve breaking into a gasway
• The HSE gives the removal or replacement of electric thermostats and on/off timer switches as examples, and says the people doing it do not need to be Gas Safe registered, though they must be competent
• The same code says gas work also covers anything that could affect the gas safety of an appliance, such as combustion seals and the appliance's own controls
• Gas Safe Register's factsheet says a boiler case held on by several screws is normally a functional part of the appliance, and someone who is not registered should not remove it

• In England, Part P of the Building Regulations makes only three kinds of home electrical work notifiable: a new circuit, the replacement of a consumer unit, and additions or alterations to circuits around a bath or shower, or in a room with a swimming pool or sauna
• Replacing a programmer, timer or room thermostat with a smart one on an existing circuit is not notifiable, and neither is adding a fused spur outside a bathroom
• Non-notifiable work must still be safe under Part P and should follow the wiring regulations (BS 7671): power isolated and proved dead, connections made properly, the system tested
• A new circuit from the fuse board, or electrical work by a bath or shower, needs a registered electrician or a building notice before work starts

• Its marketing says the kits are designed for easy DIY installation, with step-by-step instructions in the app
• Every box contains a manual for professional installers, and tado° says you can have it professionally installed if you prefer
• Its UK terms say tado° recommends professional installation and that self-installation is at your own risk
• For a new system boiler with no controller, or a direct connection to the wiring centre, tado° says to contact a heating engineer
• It warns against installing from YouTube videos, online forums or AI-generated instructions, which it says could damage the heating system
• As checked on 31 October 2026, tado°'s UK shop offers fitting by a third-party installer as an option on its wireless starter kits only, not on its wired or radiator thermostat kits

A vetted pro prices your job from photos of the boiler, your existing controls and the tado° kit, and the JACK app shows you that fixed price before you book.

What is on your wall now decides the job. A wired thermostat swapped for a Smart Thermostat X on the same cable is the simplest. A receiver in place of a heating and hot water programmer, an old wireless thermostat and its receiver to take out of the circuit, or a home split into zones takes longer. A Smart Radiator Thermostat is simple on its own, so a house full of them is priced on the number of radiators and the valves they sit on.

Every device goes on one booking for one price: the thermostat or receiver, a Bridge X if your kit needs one, and radiator thermostats for each room. Other jobs, such as a smart doorbell, can go on the same visit. Where parking has to be paid for, it is added at cost and agreed before you book.

Prefer to pay for the pro's time? Hourly hire works too: as a guide, smart home installation is typically £45–£95 per hour.
