WattBox Power Ltd (“we”, “our”, “us”) provides commercial solar and battery energy storage systems designed to help businesses reduce their energy costs and increase energy independence.
By using this website, you confirm that:
We reserve the right to suspend or terminate access if we suspect misuse or unauthorised activity.
WattBox Power Ltd designs, supplies, and supports energy storage and solar systems. Product details, technical specifications, and pricing displayed on the website are for informational purposes only and do not constitute a binding offer.

We reserve the right to modify product specifications, availability, or prices at any time.
Orders are confirmed only upon receipt of a signed agreement or purchase order and cleared payment of any required deposit or full amount.
Invoices must be paid by the due date stated on the invoice.
Title to goods remains with WattBox Power Ltd until full payment has been received.
Estimated delivery and installation timelines are provided in good faith but are not guaranteed.
We are not liable for delays due to events beyond our control (e.g., supplier shortages, transport issues, or adverse weather).
Risk in the goods passes to the customer upon delivery or installation, whichever occurs first.
All performance estimates (including energy generation, payback, and savings) are illustrative only and based on typical assumptions such as solar irradiance, load profiles, and tariff rates.
Actual performance may vary due to site-specific conditions, usage behaviour, and weather patterns.
Product warranties are provided by the respective manufacturers (e.g., Victron, Pylontech, etc.). WattBox Power Ltd may assist with warranty claims but is not responsible for manufacturer warranty decisions.
WattBox Power Ltd will not be liable for:
Nothing in these Terms excludes or limits liability for death or personal injury caused by negligence, fraud, or any liability that cannot be limited under UK law.
All content on this website, including text, images, logos, diagrams, and software, is the property of WattBox Power Ltd or its licensors and is protected by copyright and trademark laws.
You may view or print materials for personal or business reference only but may not copy, reproduce, or redistribute content without written permission.
Where you submit a request for an energy storage feasibility study, WattBox Power Ltd may, with your explicit consent, retrieve historical meter consumption data for your property. The following terms apply to this process:
We retrieve historical half-hourly electricity and/or gas consumption data from your meter for the purpose of producing a one-off energy storage feasibility study. No other use is made of this data.
There are two routes, and which one applies depends on your meter. Where your meter is on the national smart metering network, we use the n3rgy data service. Where it is not — which is common for larger commercial and agricultural supplies with half-hourly settled or advanced meters — we request the data directly from your electricity supplier, or from the Data Collector or Data Service it has appointed, using the signed Letter of Authority you provide. Both routes are covered by the same consent, and you sign for both at the same time. At the same time you also sign a separate Letter of Authority allowing us to deal with your electricity Distribution Network Operator about a grid connection for your site — see clause 9.7.
n3rgy data service (https://n3rgy.com) is used by WattBox Power Ltd to interface with the national smart meter systems in order to collect, store, manage and share with WattBox Power Ltd your smart meter data. This service uses the Smart Energy Code (https://smartenergycodecompany.co.uk) Party credentials and Party ID of N3RGY DATA LIMITED, incorporated and registered in England and Wales with the company number 11712674 whose registered office is at Prennau House Copse Walk, Pontprennau, Cardiff, Wales, CF23 8XH.
Where we request data directly from your supplier or its appointed data agent, we act as your nominated agent under the authority you have signed. That 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.
Your explicit consent is required before any smart meter data is accessed. Consent is obtained via a signed Letter of Authority or digital consent form prior to any data retrieval taking place. By providing consent you confirm that you are the legal owner or authorised occupier of the property and that you have been in occupation for a minimum of 12 months.
Consent is granted for a single, one-off data retrieval only. No ongoing or recurring data access will take place.
Consent is valid only for the duration of the single data retrieval event. Where your data is accessed through the national smart metering network, WattBox Power Ltd will proactively withdraw consent via the n3rgy API within 5 working days of completing your data retrieval. Where data is requested directly from your supplier or its appointed data agent, the Letter of Authority is valid for 12 months from the date you sign it unless you withdraw it sooner.
You may withdraw your consent at any time before this by:
Following receipt of a withdrawal request, access to your smart meter data will be removed via the n3rgy API within 5 working days. Where a Letter of Authority has been sent to your supplier or its appointed data agent, we will confirm to them that the authority has been withdrawn.
Meter consumption data is deleted within 30 days of your feasibility study being delivered to you, however it was obtained. 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.
You have the right to access, correct, or request deletion of your personal data at any time. To make a request, contact us at hello@wattbox.co.uk. You also have the right to lodge a complaint with the Information Commissioner's Office (ICO) at ico.org.uk.
The consent form also includes a Letter of Authority appointing WattBox Power Ltd as your commercial contact with the electricity Distribution Network Operator (DNO) for your site. It authorises us to prepare and submit grid connection applications for a proposed solar and/or battery energy storage installation (including G98 and G99 and budget or formal connection applications), to correspond with the DNO about them and about the site's existing connection, and to request and receive network data, technical information and connection offers on your behalf.
This authority does not permit us to accept any connection offer, or to enter into, amend or terminate any contract or agreement, on your behalf; any offer requiring acceptance will be referred to you, and any application or connection charges remain your responsibility. It is valid for 12 months from the date of signature unless withdrawn sooner, and you may withdraw it at any time using the contact routes in clause 9.4 — where an application is in progress we will tell the DNO about the withdrawal.
