UNDERFLOOR HEATING
Could graphene retrofi t solution be the answer for a capital built on Roman roads?
W
ith London still shaped by 2,000-year-old routes and Victorian infrastructure, Save- MoneyCutCarbon says new materials must
be integrated into old buildings rather than relying on demolition-fi rst sustainability. One solution could be a new graphene-enabled electric underfl oor heating system From Roman street patterns still shaping mod-
ern roads to Victorian drainage systems built for a much smaller population, London is a city trying to deliver a 21st-century low-carbon economy through infrastructure inherited from another age. Even West- minster, where national energy policy is shaped, sits within a historic estate that refl ects the scale of the challenge.
With buildings accounting for an estimated 68% of
the capital’s carbon emissions, SaveMoneyCutCarbon, the integrated decarbonisation delivery platform, is warning that the city’s retrofi t challenge has reached breaking point, and that surface-level upgrades will not be enough. The next phase of decarbonisation must focus on integrating new materials into the build- ings London cannot simply demolish and replace.

infrastructure in existing buildings without treating retrofi t as a blunt replacement exercise. The platform brings graphene-enabled electric underfl oor heating into commercial retrofi t, using an ultra-thin, low-voltage system that can sit discreetly beneath fl oor fi nishes, alongside the design, specifi cation, installation support, commissioning and measurement & verifi cation needed to deliver low-carbon upgrades with less disruption. The graphene-enabled electric underfl oor heating is said to deliver even radiant warmth without major mechanical upgrades. For London’s ageing estates, where space constraints, planning sensitivities and legacy infrastructure often limit retrofi t options, outdated heating is becoming both a carbon challenge
and a commercial risk. With SaveMoneyCutCarbon’s Net Zero Reality Index fi nding that 75% of businesses say rising costs are delaying or scaling back energy, water and carbon reduction plans, JustHeat Pro is said to close that gap by giving organisations a practical, low-disruption way to upgrade heating in real buildings while evidencing performance through verifi ed data. Mark Sait, chief executive of SaveMoneyCutCarbon,
said: “The capital has to make old buildings work for a new energy reality, which means retrofi t needs to move beyond surface-level upgrades and start integrating better materials into the fabric of existing estates. Simon Turek, chief executive of Haydale plc, said:
“Graphene gives the built environment a practical way to use advanced material science in real retrofi t conditions. Older buildings need technologies that can be integrated with minimal disruption. JustHeat Pro combines Haydale’s graphene- enabled heating technology with the delivery support needed to specify, install and evidence performance across commercial estates.”
