Britain's energy price cap rise is a bull market for heat equity

As Great Britain's energy bills head toward £2,000 a year, a fintech app lets households tokenise their heated lounge and sell it to the neighbours.

With Great Britain's energy price cap set to push typical bills toward £2,000 a year, a startup has a fix. It lets households sell shares in their one heated room to neighbours. A jumper is now a premium feature.

A London startup has responded to the rising energy price cap by letting households sell fractional shares in the one room they can afford to heat. The app, WarmCap, launched on Saturday. It calls the product "heat equity."

The timing is pure alpha. Typical bills in Great Britain are forecast to jump by £276 a year from January, to the equivalent of nearly £2,000. Experts suggest switching deals and insulating the loft. WarmCap suggests something bolder: tokenising the lounge.

The model is beautifully lean. You heat one room. Three neighbours each buy a third of it, which lets them sit in it on a rota. You get liquidity, they get ambient warmth, and nobody touches the thermostat, which the terms of service describe as "a legacy interface." Any shareholder who misses their shift forfeits it to a waiting list. The company calls this "churn." The neighbours call it standing in the hallway in a coat.

"Being cold isn't a cost. It's an underleveraged asset," said WarmCap's founder. "We're not making homes warmer. We're making warmth scarcer, which is basically the same thing but with a valuation."

The company has already pivoted once, after early users asked whether they could just buy a jumper. That feature is now in beta as a premium subscription tier.
