About Add2Rad
Add2Rad solves the biggest barrier to heat pump adoption in the UK — radiators that aren’t fit for low-temperature systems. Discover how we’re changing heating retrofits for good, without ripping homes apart.
We Fix the Radiator Problem.
The UK is ready for heat pumps.
But millions of homes aren't.
Old radiators, small rooms, and disruption-phobia are stopping homeowners, landlords, and installers from upgrading to low-carbon heating.
That’s the problem Add2Rad exists to solve.
❌ The Retrofit Bottleneck
“The biggest barrier to heat pump rollout isn’t the heat pump — it’s the radiators.”
— Energy Systems Catapult, 2023
25 million UK homes have legacy radiator systems
That means:
- Radiators too small for low-flow heat pumps
- Heating systems running inefficiently at higher temperatures
- Installations that demand messy upgrades and weeks of disruption
- Projects stalling. Quotes cancelled. Targets missed. Comfort compromised.
✅ The Add2Rad Solution
Add2Rad is a simple, smart, add-on heating system that gives your existing radiator circuit the boost it needs — with no need to rip out walls, swap every radiator, or trash the décor.
It works by adding high-efficiency skirting-level emitters alongside your current radiators, delivering up to +90W per metre of heat at low flow temperatures.
In plain English:
You keep your radiators. You avoid disruption. You make heat pumps work — as they should.

Why It Matters
Britain’s heat pump targets can’t be met by ripping out radiators in millions of homes.
Add2Rad unlocks the transition to low-carbon heating with less labour, less cost, and less disruption — while keeping rooms warm, energy bills down, and homes intact.
We're building a retrofit future that works as fast as it needs to.
