Voltview is a UK-based energy technology startup, helping businesses reduce costs while accelerating their journey to net zero. The company tackles this challenge by combining smart data, tariff comparison, and retrofit recommendations into a single streamlined platform.
We spoke with Pierre Tabet, Founder and CEO of Voltview, about how the company began, the growing role of smart data schemes like Perseus, and Voltview’s contribution as part of the Perseus technical advisory group. We also explored how banks, eager for more accurate data to strengthen their ESG reporting, are likely to see Perseus as a critical enabler.

Ross: How did Voltview begin?
Pierre: So, I started Voltview just over two years ago. I’d always been interested in the energy sector, having previously worked as a back-end engineer for an energy management company. When I moved back to the UK, I knew I wanted to stay in that field.
At the time, I began speaking to business owners who were unknowingly in the middle of the energy crisis. Many were still on fixed contracts, but when their renewals came up, their bills more than doubled. Hospitality businesses were hit especially hard because of their high energy consumption. For example, one fish and chip shop I spoke with saw annual bills jump from around £10,000 to £35,000. That kind of increase can threaten the viability of a business.
We saw huge pressure on SMEs, and I realised that’s where Voltview should focus. Early on, I had conversations with Smart DCC, who pointed me towards a government grant for smart tariff comparison in the non-domestic sector. Now, we just missed out on getting that grant, but we were still interested in the space. And from there we pivoted slightly.
Rather than just offering comparisons, we wanted to combine switching with retrofits, so businesses could save on tariffs and reduce consumption. Think of it like Booking.com: when you book a flight, they also suggest hotels, car hire, or insurance. But in energy switching, businesses never get offered solutions like heat pumps, EVs, or electrification measures, even though the data used for switching could easily support those recommendations. With reforms like market-wide half-hourly settlement, that data is more valuable than ever. It felt wasteful for switching to end with just a new tariff, when it could instead trigger bigger energy and cost-saving changes.
Ross: This makes a lot of sense to me. Especially now, what with rising energy costs. It reminds me of Open banking and how it opened up consumer choice. How do you ensure the data accuracy and transparency when you’ve got these tariff comparisons?
Pierre: Open banking is a great comparison as it allows you to share financial data with authorised third parties, who then provide tailored services. As I’m sure you know, the government now wants to replicate that model in energy, having passed the Data Use and Access Act.
This is especially relevant in the commercial sector- currently about 80% of UK commercial buildings aren’t compliant with the EPC B rating required by 2030. Non-compliance could mean fines. To address this, businesses need access not just to energy data but also building data, credit scores, financial history, everything required to prioritise and fund retrofits.
What’s really cool now is, a lot of the administrative work which took up a lot of energy consultants’ time, can now be done with AI, so that they’re only working on sort of the high value work.
Ross: That’s really interesting. How exactly can EPC data be linked to financial impact? Is there a link to green mortgages here, in a similar vein to SME emissions data being linked to green finance with Perseus?
Pierre: Absolutely. Perseus is a great example and we’ve been lucky to contribute on the technical side. It provides a trusted way to share Scope 2 emissions data with banks, who in turn reward businesses with lower interest rates.
The bigger picture here is increasing electrification. In the UK, only about a quarter of energy use is electricity, compared to roughly half in Norway. To close that gap, we need incentives like cheaper capital for retrofits, particularly for SMEs. Many owners are busy running their businesses, so making retrofits easy is critical to driving uptake.
Ross: And so you’ve got EPC data, half-hourly meter data, and financial data – how hard is it to bring all that together on one platform?
Pierre: It is challenging. Only about 60% of UK business meters are smart compared with roughly 95%+ in some European countries, so many firms are effectively flying blind. The first hurdle is getting half-hourly data; the second is aligning it with building and financial data. We start with specific use cases and design the simplest possible customer journey around them.
Ross: Very cool. And as you mentioned, the Data Use and Access Act should hopefully accelerate this work and smart data schemes like Perseus. I also saw on your website that your clients save 17% on energy bills. Can you share an example of this?
Pierre: Sure. Savings usually come from two areas: matching clients with tariffs that suit their load profiles, and cutting waste. One example was a restaurant kitchen where the ventilation system was switching on at night. The owners had no idea until we flagged it with half-hourly data alerts. Fixing that single issue accounted for about a third of their total savings. So really the savings are already in the data- you just need the right tools to uncover them.
Ross: Let’s dig into Perseus a bit more. How have you found being involved in its development?
Pierre: It’s been a great experience. We’re part of the technical advisory group, which has focused on making Perseus trustworthy, scalable, and incredibly easy for users. Ultimately, it’ll be as simple as ticking one box. In December, when Perseus trialled the process manually, it gave us confidence in how it can work at scale. We’re now about six months away from real-world rollout, and we’re excited to integrate it into our ecosystem.
Ross: And what would that integration look like for Voltview?
Pierre: It might not sit directly on our platform. We may simply guide clients to enable it through their accounting software. The point is that all our customers gain access to cheaper capital for retrofits, regardless of where they switch it on.
Ross: Do you think financial institutions are ready to adopt Perseus and scale up green finance for SMEs?
Pierre: Increasingly yes, the real bottleneck is data quality not intent. Almost half of FTSE 100 companies have had to restate climate metrics every year, mostly due to emissions in their suppliers. Banks and lenders want more reliable data to strengthen their own ESG reporting and sustainability-linked products. Perseus helps by providing verifiable upstream data so there is less estimation, fewer restatements and more confidence to deploy capital.
Ross: Great. To wrap up, what’s next for Voltview?
Pierre: We are nearing the end of the Smart Data Challenge funded by the Department for Business and Trade. The challenge has been to incorporate more cross-sector data into our platform. Our next step is to launch use cases that almost any SME can tap into by sharing their energy, building and financial data. We will announce these later this October as we complete the Smart Data Challenge.
