• Website: https://www.wattbox.co.uk
• Company number: SC866786
• Registered address: 28 Ardmore Gardens, Drymen, Glasgow, G63 0BD
• Registered: United Kingdom

We may collect and process the following information:

a. Information you provide directly:

• Name, business name, email address, and phone number (e.g., when completing a form or requesting a quote)
• Details about your business energy usage, property type, and other project-related data
• Any correspondence you send to us

b. Meter data:

Where you provide explicit consent, we may collect historical meter consumption data (electricity and/or gas) for properties you own or occupy. This is retrieved either via n3rgy data Ltd using the national smart meter infrastructure, or — where your meter is not on that network — directly from your energy supplier or the Data Collector or Data Service it has appointed, using the Letter of Authority you have signed. See Section 4 and Section 5 for further details.

c. Information collected automatically:

• Device type, browser, IP address, and pages visited
• Cookies and similar technologies for analytics and advertising purposes

d. Third-party data:

We may receive information from trusted partners (e.g., marketing platforms, analytics providers, or payment processors) to improve our services and communications.

We use your data to:

• Respond to your enquiries and provide quotations or product information
• Process your order and manage your account
• Retrieve and analyse your smart meter consumption data to produce an energy storage feasibility study (where consent has been given)
• Improve our website, tools, and customer experience
• Send marketing communications (only where you've opted in)
• Analyse traffic and campaign performance using tools like Google Analytics, Meta Ads, and similar

We never sell your data to third parties.

We process your data under one or more of the following lawful bases:

• Consent — for marketing or optional communications, and for the retrieval and processing of your meter consumption data. Where we access your meter data, by either route described in Section 5, we will always obtain your explicit consent beforehand via a Letter of Authority or digital consent form. You may withdraw this consent at any time (see Section 7).
• Contractual necessity — to provide requested products or services
• Legitimate interests — to improve our services and website performance
• Legal obligation — to comply with tax or regulatory requirements

Where you provide consent for us to access your meter data, the following applies:

• Purpose: Meter consumption data is retrieved solely to produce a one-off energy storage feasibility study for your property. It is not used for any other purpose.
• How it is obtained: Where your meter is on the national smart metering network, data is retrieved via n3rgy data Ltd (company number 11712674, registered at Prennau House Copse Walk, Pontprennau, Cardiff, CF23 8XH), which operates under the Smart Energy Code (SEC) using its SEC Party credentials and acts as our data processor. Where your meter is not on that network, we request the data directly from your energy supplier or the Data Collector or Data Service it has appointed, acting as your nominated agent under the Letter of Authority you have signed.
• Data retrieved: Historical half-hourly electricity and/or gas consumption data for your property, together with the meter and supply details needed to identify the supply and interpret the readings.
• Scope of the authority: The Letter of Authority is limited to obtaining data. It does not permit us to enter into, amend, terminate or renew any contract, to change supplier, or to make any change to your account or metering equipment. We receive no commission or other payment from any energy supplier.
• Grid connection authority: Where you sign the DNO Letter of Authority, we share your name, site address and meter point details with the electricity Distribution Network Operator (DNO) for your area in order to prepare and submit grid connection applications for your site (e.g. G98/G99), correspond with the DNO about them, and receive connection offers on your behalf. That authority names us as your commercial contact only — it does not permit us to accept any offer, enter into any contract, or incur any charge on your behalf, and it is valid for 12 months unless withdrawn sooner.
• Retention: Consumption data is deleted within 30 days of your feasibility study being delivered to you. Where data was accessed through the national smart metering network, consent evidence records are retained for a minimum of 4 years as required under the Smart Energy Code.
• Withdrawal: You may withdraw your consent for meter data access at any time by emailing hello@wattbox.co.uk. Following receipt of a withdrawal request, smart meter access will be removed via the n3rgy API within 5 working days, and where a Letter of Authority has been sent to your supplier or its appointed data agent we will confirm to them that it has been withdrawn. WattBox Power Ltd will also proactively withdraw consent within 5 working days of completing your data retrieval.

We may share your data with:

• Service providers who help us operate our website, CRM, or analytics (e.g., Webflow, Xano, WeWeb, Stripe, Google Analytics)
• n3rgy data Ltd — for the purpose of retrieving smart meter consumption data where you have provided consent
• Your energy supplier and its appointed Data Collector or Data Service — where your meter is not on the national smart metering network, we present your signed Letter of Authority to them in order to obtain your consumption data, and they return that data to us
• Your electricity Distribution Network Operator (DNO) — where you have signed the DNO Letter of Authority, to prepare and submit grid connection applications for your site and receive connection offers and related correspondence on your behalf
• Delivery or logistics partners to fulfil orders
• Legal or regulatory authorities when required by law

All partners are required to comply with UK GDPR data protection standards.

We retain your data only as long as necessary for the purposes set out in this policy. Smart meter consumption data is deleted within 30 days of your feasibility study being delivered. You can request deletion of other personal data at any time.

Under the UK GDPR, you have the right to:

• Access the personal data we hold about you
• Request correction or deletion of your data
• Withdraw consent at any time — this applies both to marketing communications and to meter data access. Withdrawal of consent for smart meter data will result in access being removed within 5 working days; where a Letter of Authority has been sent to your supplier, its appointed data agent, or your Distribution Network Operator, we will confirm to them that it has been withdrawn.
• Object to processing based on legitimate interests
• Lodge a complaint with the Information Commissioner's Office (ICO) at ico.org.uk
