Saving while the market swings
Glass toughening means a furnace running at 620–680°C. Without stopping. That's a lot of energy usage. So when the price of energy shifts in volatile markets, that exposure can be make or break for any indipendant business. Because RED's tarriffs aren't tied to the wholesale market, it meant Ashton avoided the hits that every other supplier was passing on early in 2026.
A bill that shows what you're actually paying for.
Non-commodity costs typically make up 60% of a business energy bill. They're set by government and network bodies, not by suppliers. But, what a supplier controls is whether they show them, explain what they fund, and tell you when they're likely to change. On RED™, passthrough costs are billed at cost with no margin added, not bundled into an inflated unit rate.
Extra savings. Unlocked for all.
Ashton's deal doesn't just save them transaction costs.
Most businesses like Ashton are paying non-commodity charges they could have reduced. P442 connects a business to eligible renewable generation - and when that link is made, some of those charges come down. The saving appears as a RED Plus Benefit on the invoice every month. For Ashton Glass, that's around £6,000 a year back.
