One of the most common questions we're asked is simple: will a heat pump actually cut my bills? The honest answer is that it depends — but for many homes the savings are real and lasting.
Why heat pumps are efficient
A gas boiler turns one unit of energy into a little less than one unit of heat. A heat pump does something cleverer: it moves heat rather than burning fuel, delivering up to three units of heat for every unit of electricity it uses. That efficiency is where the savings come from.
What affects your savings
Your savings depend on several factors, which is why we design each system carefully rather than making blanket promises.
- The system you're replacing (older oil and LPG systems usually show the biggest savings)
- How well insulated your home is
- Your electricity tariff — including heat-pump-friendly tariffs
- How the system is sized and set up to run efficiently
Running the system well
Heat pumps work best running steadily at lower flow temperatures, keeping your home at a consistent, comfortable warmth rather than blasting heat in short bursts. We'll show you how to run yours efficiently at handover.
A realistic expectation
If you're moving from an older oil or LPG system, you may see a meaningful reduction in running costs. If you're on mains gas, savings can be more modest but you gain lower carbon emissions and a future-proof system. We'll always give you an honest picture for your home.
