tan. zen. energy.

Tan is Welsh for fire.

Zen means balance. Calm. Stillness.

Fire and balance. Heat and harmony. The name reflects how we think about energy — not as a commodity, but as something your home generates, stores, and uses in balance.

Every technology we choose is tested against that principle. Does it work long-term? Is it genuinely better than the alternative? Will it still be relevant in twenty years? If not, we don't install it.

“I've been thinking about energy independence for fifteen years.”

Not as a business plan — as a genuine obsession. How do you generate your own electricity? How do you store it properly? How do you heat your home efficiently using what you've generated? And how do you do all of it with technology that won't be obsolete in five years?

While I was running Build Wales, this research was always running in the background. Solar, battery chemistry, graphene technology, sodium ion storage — fifteen years of following where the science was going before it became mainstream.

Tanzen Energy is that research, finally built into a business.

The technology we've chosen reflects how I think. Haydale's JustHeat graphene heating is the most advanced heat mat system available — and we're the trusted installer across Carmarthenshire, Ceredigion and Pembrokeshire.

We're not interested in selling you something that will be outdated in five years. We're building the energy stack your home will still be running on in twenty.

That's Tanzen Energy.
