Electric Heating UK: The Key Questions Homeowners Are Asking (And the Fast Answers You Actually Need)

If you are researching Electric Heating UK, Best Electric Heating Systems for UK Homes, or trying to compare modern electric heating with your existing gas system, you have probably already discovered that the information online is either outdated, over-simplified or based on legacy technology that no longer reflects what is possible. Below are the core questions people are searching today — and the short, factual answers that matter before you consider any upgrade.

For the full deep-dive, you can read the complete article here:

1. Is Electric Heating in the UK Still Expensive Compared to Gas?

Electricity costs more per unit than gas, but modern systems no longer rely on old-style direct electric radiators. Air-to-air heat pumps can deliver three to four units of heat for every unit of electricity consumed, which changes the economics entirely when designed properly. The full breakdown is in our main article.

2. What Is the Best Electric Heating System for UK Homes?

For most properties, especially older homes and mixed insulation, air-to-air heat pumps currently offer the best balance of efficiency, comfort and running cost. They heat quickly, work in real British weather and require far less disruption than water-based heat pump systems. You can read why Caldo designed Optima around UK homes in the full article.

3. What Should I Consider Before an Electric Heating Upgrade?

The biggest mistake homeowners make is replacing old radiators with slightly newer ones. True upgrades involve moving to systems that optimise around tariff windows, occupancy, insulation levels and daily usage patterns. Modern systems do this automatically. We explain the difference in detail in the main guide.

4. How Do Electric Radiators Compare to Gas Heating in Efficiency?

Traditional electric radiators convert electricity to heat with no intelligence, no strategic energy use and no thermal adaptation. Gas boilers are limited by their fuel efficiency, usually topping out around 90 percent. Modern air-to-air systems can deliver several times that efficiency because they move heat rather than generate it. The real-world comparison is covered fully in our main post.

5. Can Electric Heating Work in Older, Poorly Insulated UK Homes?

Yes — but only if the system is designed for real British housing, not idealised laboratory conditions. Many heat pumps underperform because they were installed without considering insulation variance or thermal behaviour. Caldo engineered Optima specifically for the types of homes where most traditional heat pumps struggle. More on that in the full article.
