5.1 Charging electricity at SimpleSockets, availability, accessability
5.1.1 The customer can charge his/her electric vehicle (EV) at SimpleSockets using an authorised, activated SmartCable. Except when otherwise communicated, the SmartCable will be activated at the time of receipt.
5.1.2 SimpleSockets are operated by public or private charge point providers. The SimpleSockets can only be used with authorization of the charge point provider. If the charge point is installed on the customer’s premises, the customer has to grant access to the charge point provider when necessary. The charge point provider can remove its charge points if this is required. ubitricity does not assume responsibility for the availability, functioning or accessibility of SimpleSockets. Customer shall not have the right to use a specific SimpleSocket. SimpleSockets shall be used for charging EVs only.
5.1.3 When using the SmartCable, the customer shall charge his/her EV at parking spots with sufficient network coverage on a regular basis (and in any case no less than once a month) to ensure a proper data transfer. Customer shall avoid consecutive charging processes without sufficient network coverage. The customer shall not use the mobile radio unit for any other purpose than the transfer of measurement data.
5.1.4 Before the exchange or shut down of the SmartCable, the customer shall carry out a charging process at a charging spot with sufficient network coverage.
5.1.5 The customer shall notify ubitricity immediately by phone (+44 800 024 6279) or via e-mail (firstname.lastname@example.org) in the event of disruptions, damage or loss of the SmartCable. ubitricity shall lock the SmartCable as soon as reasonably practicable after receiving such notification. Customer shall be liable for any charging processes that are conducted before such notification. If the locking of the SmartCable is delayed due to ubitricity’s fault, the customer shall not be liable for charging processes conducted by unauthorized third parties, unless the customer is also at fault. The customer shall also be liable for offline-charging processes after the locking. To mitigate this risk, the customer can elect to notify ubitricity upon signing the contract that no offline-charging shall be possible.
5.2 Supply and billing of the withdrawn electricity
The SimpleSocket is directly connected to the distribution grid, and the customer’s mobile electricity supplier (whether ubitricity or another) provides electricity at the SimpleSocket. ubitricity shall measure the withdrawn electricity and either invoice such amounts to the customer, or forward the usage data to the respective supplier for billing purposes.
5.3.1 ubitricity measures the electricity withdrawn by the customer via the SmartCable, and ubitricity shall determine the way such measurements are calculated (consumption measuring, meter readings etc.).
5.3.2 Customer shall allow ubitricity or a third party access to the SmartCable, insofar as this is necessary for: (i) billing purposes; (ii) the fulfillment of the contract; (iii) compliance with any legal duties; or (iv) the management of energy business processes. Prior notice of such required access shall be given at least one week in advance. If the customer is unable to provide access on the requested date, customer shall offer a prompt alternate date.
5.3.3 The customer must not open the enclosure of the SmartCable. The opening of the enclosure may lead to the loss of the calibration validity. The customer shall notify ubitricity immediately of an suspected opening or severe damage.
5.3.4 Once the calibration validity (usually 8 years) has expired, the SmartCable will be deactivated. ubitricity will inform the customer of the impending expiry in advance. Customer has the right to terminate the mobile electricity contract at the time the calibration validity expires. If customer does not terminate the contract, the contract shall remain in force, including all payment obligations. Customer shall be responsible for restoring the calibration validity of the SmartCable, or to purchase another calibrated SmartCable.
5.4 Online platform
5.4.2 The customer is able to access his personal data via the password-protected ubitricity information portal (available at https://www.ubitricity.co.uk/mobile-electricity-portal.
5.4.2 The customer shall protect his/her access data and ensure that third parties do not obtain such access data. Any actual, pending or suspected loss of the access data shall be reported to ubitricity immediately either by phone (+44 800 024 6279) or via e-mail (email@example.com). The customer must then change his/her password immediately.
5.5 Release from obligation
5.5.1 If a force majeure event occurs, ubitricity shall not be liable for failing to providing any services for the duration of the force majeure event. ubitricity shall also not be obliged to provide, or held liable for failure to provide, the services if prevented by reasons beyond ubitricity’s control.
5.5.2 The indicated charging capacity for each charging point is the maximum charge power. ubitricity is entitled to reduce or interrupt the charge power temporarily to the extent that ubitricity considers it reasonably necessary for reasons of public safety, statutory compliance, safety of network operation (especially at high grid utilisation in the network peripherals of the charging point), or for maintenance of the grid integrity. In these cases, ubitricity is not liable for any damage or financial losses that occur from the lower charging capacity.
5.5.3 ubitricity is released from any liability for failure to provide the services in the event of electricity cuts or blackouts that ubitricity is not responsible for, to the extent that they result from a disturbance of the network operation, network connection or the charge point provider’s customer system. At the customer’s request, ubitricity will immediately provide such information about the cause of damage as it is aware of or which ubitricity can reasonably discover.
5.5.4 If ubitricity is unable to provide the services for reasons described in sections 5.5.1, 5.5.2 or 5.5.3 for more than 4 weeks, the customer is entitled to terminate the contract without prior notice. Any further claims, including for compensation, are excluded, unless otherwise stated in section 9.
5.6 Prices and price changes
5.6.1 The net invoice amount for the supply of mobile electricity (before VAT) consists of (1) the monthly base price, (2) the electricity price per kWh, multiplied by the actual withdrawal and (3) the amount of charging processes, multiplied by the transaction price per charging process.
5.6.2 The price for mobile electricity per kWh includes the purchasing and sales costs, all costs paid to grid operators, costs of billing, concession fee as well as sales and electricity tax.
5.6.3 VAT due and payable on the amounts applicable from time to time will be added to the prices described above.
5.6.4 Other changes in cost may be made unilaterally by ubitricity at its reasonable discretion upon prior notice to customer. The customer can request judicial review of these price changes.
5.6.5 If ubitricity changes costs unilaterally, only the costs described in section 5.6.2 may be taken into account. Price changes will be based on balancing the changes in cost (increases and reductions) of each price component by applying a uniform standard (factual and temporal). ubitricity will examine the costs annually. If ubitricity’s costs of providing the services have increased, ubitricity may adjust the prices payable by customer accordingly. If the costs have decreased, ubitricity will also adjust the prices accordingly. Due to the fact that cost reductions are made in the same way as cost increases (factually and temporarily), cost reductions affect the prices at least as much as increases. Cost reductions will not be passed on later than cost increases.
5.6.6 Sections 5.6.4 and 5.6.5 also apply to future taxes, dues or other state-imposed additional burdens or reliefs concerning procurement, generation, grid usage (transmission and distribution) or consumption of electricity.
5.6.7 Any changes in pricing or charges will be notified to the customer no less than six weeks in advance. The notification will describe the changes, compare the increased or decreased price with the current price, state when the change will start, explain why the change is happening and state what actions the customer can take.
5.6.8 If ubitricity changes the prices to the customer’s disadvantage, ubitricity may ask the customer to explicitly agree to the increase in price. ubitricity will give advance notice as described in section 5.6.7 of the proposed change. Any ordinary termination rights remain unaffected.
6 Use of data, data transfer and data protection.
6.1 At the end of each charging process, the SmartCable will transfer the measurement data via mobile radio technology to ubitricity. If there is no sufficient network coverage, the SmartCable secures the data and transfers it as soon as there is a connection.
6.2 The SmartCable collects the following data with each charging process at a SimpleSocket: starting and ending time, initial, final and in-between readings every 15 minutes as far as they are relevant for the billing regarding the connection user and the grid operator, the ID of the SmartCable and the SimpleSocket used and the electronic signature of the data set. There will be no data collection by ubitricity for charging processes at charging spots other than SimpleSockets.
6.3 The collection, processing and use of measurement data of the mobile electricity customer will be executed by Power Data Associates Ltd, Wrest Park, Silsoe, Bedfordshire, MK45 4HR.
6.4 if the customer has entered his/her email address during the roaming app registration process, that email address will be stored in order to generate an App-EVCO-ID and assign it to the customer for the purpose of contract implementation.
7 Data transfer from charge points in London to the relevant Local Authority, Transport for London (TfL), London Councils and Greater London Authortity
7.1 Regarding charge points in London, ubitricity is entitled to share customer data under terms of confidentiality with the relevant Local Authority regarding the charge points, and other applicable authorities, bodies or public entities (including, but not limited to TfL, London Councils and Greater London Authority) (“Authorised Entities”). If the data is personal data, it will be anonymised before transmission.
7.2 Anonymised data will be used by the Authorised Entities mentioned above under terms of confidentiality for purposes of:
Operating and managing their charging point scheme, research and policy purposes to reduce carbon emissions, improve air quality and reduce congestions such as the impact of EV-charging on the grid, informing the development of the scheme or a new scheme, transfer the service to a different charge point provider, compliance and regulation duties, reporting on the scheme, marketing of other government and mayoral programmes, subject to the requirements of the privacy and Electronic Communications Regulations 2004, as may be amended or replaced, and identifying fraudulent use of their scheme. The Authorised Entities may share such data under terms of confidentiality with third parties acting on their behalf, if they concluded a contract regarding commissioned data processing.
7.3 The relevant Local Authority, Authorised Entities and TfL may share the anonymised data and other data that is not personal data under terms of confidentiality with third parties acting on their behalf for the purposes set out in section 7.2.
7.4 If any customer data is not anonymised, ubitricity shall first obtain the customer’s consent in order to share personal data for the purposes mentioned above. Such declaration of consent has to be given separately by the customer and is not part of this contract. Such consent can also be revoked by customer at any time. Unanonymised data will not be published.
8 Quotation, payment, default in payment
8.1 Invoice amounts and credits regarding the mobile electricity supply are due at the end of each month.
8.2 If the customer is not a consumer and, provided nothing to the contrary has been agreed upon, all prices are net prices.
8.3 Payments will be made at the discretion of the customer either via SEPA direct debit mandate, on account, via credit card or via Paypal.

Invoice amounts due will be collected from the account specified in the mandate. ubitricity shall notify the customer of the mandate reference immediately after conclusion of the contract. ubitricity is entitled to charge the customer for any costs that result from a reversal caused by the customer in breach of the customer’s duties under this agreement. If payment is made on account, payment has to be made by the due date. The date upon which payment is deemed to have been made shall be the date that the payment is actually received into ubitricity’s account, as determined by reference to ubitricity’s relevant bank account statement. ubitricity is entitled to charge an extra fee per month for payments by bank transfer.
8.4 ubitricity is entitled to offset receivables due against amounts owed to the customer.
8.5 Where payment on account has been agreed upon individually, the customer is obliged to pay the invoice on maturity (14 days after receipt of the bill). If the customer does not fulfill this obligation, he/she shall receive a reminder from ubitricity at no charge. In the event of ongoing default, ubitricity is entitled to claim dunning costs in the amount of £2.00 for any further reminder or final reminder. The customer’s right to prove that ubitricity’s actual damage caused by the default is lower than the claimed costs for pursuing the outstanding debt shall be unaffected.
8.6 ubitricity is entitled to claim delay damages in accordance with applicable statutory provisions.
9.3 ubitricity is liable without limitation for: (i) fraud and fraudulent misrepresentation; and (ii) personal injury or death caused by ubitricity’s negligence.
