tem looks after what arrives at your meter: The price of the power and the levies on it.
RenewaBlox looks after everything that happens after it: Eliminate unnecessary costs, optimise how your site is structured
and potentially get double the value out of the power you use through Heat-as-a-Service.

The foundation · in every tier
RED and RED Plus, from tem.
Whichever tier you choose, your supply comes from tem: power priced against UK renewable
generators, with the RED Plus benefit on top. It’s the first saving on the bill, before RenewaBlox changes anything on site.
RED
Power priced against UK renewablestem’s intelligent Rosso platform
Most suppliers buy your energy on the wholesale market and pass on its costs and markups. tem
don’t. Instead they build a bespoke price for your business, balanced against their own portfolio of UK
renewable generators — so you pay closer to the true cost of energy.
Your unit rate is fixed for the length of your contract
Industry non-power costs pass through at cost, with nothing added

RED+
A renewable generator linked to your usageP442 · exempt supply
Under P442, eligible UK renewable generation — such as solar or wind — is linked to
your business’s usage. On the share it covers, certain non-commodity costs, the government scheme levies,
aren’t charged. That saving is your RED Plus benefit, on top of tem’s price.

Three tiers
Start with structure. Then add heat.
Every tier includes RED and RED Plus from tem, and each builds on the one before: get the structure
of your site right first, then put its power to work as heat when your site can use it. Open any tier to see it working.
RED Plus (P442) depends on eligibility, and on
how much of your usage a linked generator covers. Example-quote figures, customer numbers and quotes are tem’s.
The tier pages are illustrative, not quotes or forecasts.
