Tadoº Smart Thermostat Offer

Last updated 31st March 2021

1. About These Terms and Who We Are

1.1 These terms and conditions (the “Terms”) form the agreement between you and us:

(a) you are the person who has purchased a Tado Smart Thermostat from us; 

(b) we, us or our is OVO Energy Limited. Our address is 1 Rivergate, Temple Quay, Bristol, United Kingdom, BS1 6ED.

1.2 Capitalised terms used in this agreement are defined in section 14.

1.3 These Terms only relate to your purchase of a Tado Smart Thermostat (“Smart Thermostat”) and are separate to the OVO Core Terms and Conditions governing the supply of electricity to you by OVO Electricity and your use of that electricity.

Accepting your order

1.4 These Terms (and the agreement between us) will come into effect when we accept your order. We will accept your order by sending you an email confirming your order after you have completed your purchase of the Smart Thermostat via our website. If, for any reason, we are unable to accept your order, we will contact you to let you know why. One of the reasons that we may not be able to accept your order could include where you do not meet our Eligibility Criteria (see sections 2 and below).


1.5 You have the right to change your mind and cancel these Terms and return your Tado to us from the date we accept your order until 14 days after the date that your Smart Thermostat is received (“Cooling Off Period”). Please see section 8 for more information on what happens if you want to cancel.

2. Eligibility

2.1 You can take advantage of this Offer if you meet the following criteria (the “Eligibility Criteria”): 

(a) You are currently an OVO Energy member and take your gas and electricity supply from us 

(b) You have a My OVO account set up 

(c) You have a standard gas combination boiler or conventional system boiler (with a separate hot water tank). Your boiler will also need to be compatible with the Smart Thermostat.  The Smart Thermostat is compatible with most boilers but there are some exceptions. See here for a list of compatible boilers. Your heating system must be in good working order at the time of Installation.

(d) You have the landlord’s permission to have a Smart Thermostat installed if you are not the homeowner.

2.2 In order to be able to benefit from the Connected Proposition (see section 3.3 below) you will need to have a communicating Gas Smart Meter or be willing to have one installed. Please note that not all OVO members will be able to have smart meters. Sometimes we can’t install smart meters in homes for practical or technical reasons. For instance, we might not be currently installing smart meters in your area or your property might not be suitable (for example, smart meters won’t be installed if there’s anything blocking access to your current meter(s)). Sometimes we won’t know this until an engineer’s been to your home. If we can’t install a smart meter in your home, we’ll let you know.

2.3 You will need an Android or iOS device with an up to date operating system, with Internet access. To fully benefit from this Offer you will need to have a smart phone to be able download the Tado app.  

2.4 You will need to register for a Tado account before your Smart Thermostat is installed so that you (or the engineer if you have opted for installation) can link your Smart Thermostat to Your Tado account. If you don’t register for a Tado account or agree to link your Tado account to your My OVO account, you won’t be able to receive any of the energy efficiency recommendations which form part of the Offer.

3. The Offer

3.1 If you meet the Eligibility Criteria, you can purchase a Tado from us for the exclusive price of £120. This price includes VAT. See “Paying for your Tado” below for details on the different ways you can choose to pay for your Tado.

3.2 Installation is not included in the price of your Tado. You can either choose to install the Tado yourself (please see the Tado website for a step by step guide) or you can choose to add installation at the checkout for an additional charge of £60 (including VAT) and we will arrange for our Installation Partner to install it for you (provided you live in an area we install in, please see our FAQs for details). Please note that we will only be able to install your Tado for you if you have an existing wireless thermostat to control your boiler.

3.3 Once your Tado is installed you can connect it to your My OVO account and receive energy saving recommendations and change the temperature of your Tado via your My OVO account (“Connected Proposition”). You can also use your Tado app to control the heating in your home (you won’t need a Gas Smart Meter installed in order to use the Tado app). 

3.4 Any recommendations we may make about your energy usage and/or potential bill savings are estimates only and any actual savings or benefits you may receive will depend on the type of heating system in your home, how your home is insulated and your energy usage patterns.

3.5 Please note that our Connected Proposition is currently in BETA testing, as such, you accept that that your Tado may not operate properly or be fully functional when controlled by My OVO, for which neither we, nor Tado will be liable. (But if this happens, we'll try to minimise any impact on you). We also reserve the right to make changes to or withdraw this offer and our Connected Proposition at any time.

3.6 An independent study has shown that installing and correctly using a Tado smart thermostat can reduce your energy use from heating by up to 31%. The study found that the Tado device can reduce heating energy requirements by 14-26% through intelligent control of the heat source (e.g. boiler or heat pump). A potential further saving of up to 7% could be achieved by turning down the heating based on the weather forecast, depending on the window sizes. If the window surfaces are relatively large, the energy saving will increase accordingly. The study can be found here

4. Paying for your Tado

Paying upfront

4.1 The total cost of the Tado if you choose to install it yourself will be £120. If you want us to arrange installation for you this will cost an extra £60. You can pay for both upfront via credit or debit card when you purchase your Tado.

Paying by installments

4.2 You also have the option to split the cost of your Tado across 12 interest free payments of £10. If you choose to ask us to install it for you the total cost will be £180, split across 12 interest free payments of £15. 

No additional payments or upfront payments of the full amount can be made if you choose to pay by installments.

4.3 In order to be eligible to purchase the Smart Thermostat via monthly installments:

(a) you must pay your bill by Direct Debit;

(b) you must have 3 months or more left on your contract; 

(c) your account must not be in arrears; and

(d) your predicted end of contract balance must be £50 or more 

We also reserve the right to undertake a credit check (see https://www.ovoenergy.com/help/credit-checks for more information), which may affect your credit rating, before accepting your order and allowing you to pay monthly.

4.3 By purchasing a Smart Thermostat from us you agree that an additional £10 a month (£15 a month if you have opted to include installation) can be added to your energy account each month and billed monthly via the Direct Debit for your energy bill.

4.4 The first payment will be added to your next bill following the purchase of your Smart Thermostat (which may be before your Smart Thermostat is installed). Your monthly direct debit may need to be increased by £10 per month (£15 if you have opted to include installation) to ensure this cost is covered. The  payment will appear on your energy bill as “Smart Thermostat”.

4.5 If you want to switch to a different supplier or switch to a different OVO Energy plan before your plan ends, then your plan will be terminated and termination fees may apply (see OVO Core T&Cs here: https://www.ovoenergy.com/terms). We will need to collect the remaining balance due for your Smart Thermostat before you leave OVO. This outstanding amount will be added to your final bill.

4.6 We also reserve the right to request payment of the remaining balance due for the Smart Thermostat if your account goes into debt or if you are otherwise in breach of these terms, see section 9.

4.7 You can opt out of OVO Smart Heating Control at any time by emailing [email protected] or calling 0330 102 7423. If you decide to opt out of OVO Smart Heating Control or we withdraw OVO Smart Heating Control in accordance with section 3.5 above, you will still be able to keep paying your monthly installments until your balance is cleared and you keep the hardware installed although you will no longer receive energy saving tips.

5. Installation

5.1 If you have bought your Tado without Installation included, you are responsible for installing the Tado yourself. We won’t be responsible and no refund will be given for any damage to the Tado or your property or any other costs, loss or damage you suffer which is caused by the incorrect installation of your Tado.      

5.2 If you have chosen to include Installation, we (or our Installation Partners) will attempt to contact you to arrange the Installation within 2 working days of you purchasing your Tado.

5.3 The Installation will also include removal and disposal of existing thermostats from your Property.

5.4 You agree to provide our Engineer with access to your Property to carry out the Installation.

5.5 You agree that you or a person authorised by you (who is 18 or over) will be at the Property during the Installation and can provide us with information about where to install your Smart Thermostat .

5.6 You will let us know if there are any issues with your Property or local restrictions which may affect the Installation, for example: local parking restrictions, steep stair climbs or long carrying distances.

5.7 Your heating system must be in good working order at the time of Installation. We will not be liable to fix any underlying problems with your heating system during the Installation.

Making good any damage

5.7 The Installation will involve drilling into the wall so by accepting these terms you are agreeing for us to carry out this work. 

5.8 Our Engineers will take reasonable care to carry out the Installation without causing unnecessary damage. We’ll fix any unnecessary damage to your Property that is directly caused by our negligence. If we remove your existing thermostat and don’t install your Smart Thermostat in the same place, you are responsible for making good any holes in the wall or cosmetic damage caused by such removal.

5.9 You also acknowledge that sometimes we have to do extra work if we cannot use existing wiring to install the Tado, and this can cause damage to things like inside and outside finishings (for example, wallcoverings and paint). You may need to redecorate, repair or restore certain areas once the Installation is completed. You will be responsible for the cost of this.

Delays and cancelled appointments

5.10 We'll try to carry out the Installation on your Installation date, but we may change this date. If we do, we'll try to notify you of any changes as soon as possible. We won’t be liable to you for any losses due to changing your Installation date, for any reason. Installations are also subject to the Government’s Coronavirus regulations and guidance in place from time to time.

5.11 We aren’t responsible for any delays or failures to carry out an Installation caused by circumstances beyond our control or which were unforeseeable, including, without limitation, where you have given us incorrect information.

5.12 We aren’t responsible for any losses you incur due to delays to your Installation, however caused. We won’t pay any compensation if we can’t complete an Installation during a scheduled appointment. 

5.13 If we aren’t able to complete any Installation in a single appointment, we’ll make an additional appointment to complete the work. Unless there are additional fees payable under these terms or which we’ve otherwise told you about, you won’t be charged additional fees for this additional appointment.

5.14 We will only carry out the work if someone over 18 is present at the Property at all times and we won’t start or continue the Installation if we believe there is a health and safety risk to our Engineers or any other person, and we won’t return to complete the Installation until that risk is resolved.

5.15 In the unlikely event that we are unable to install at your Property we will put your system back to how it was and take the Smart Thermostat back with us. We will then contact you to arrange a refund

5.16 If you cancel your Installation within 24 hours or if you are not available when we arrive at your Property, you may be charged £30 for a failed appointment. If you fail to keep an appointment on more than two occasions, we may charge an additional fee.
