In this guide, we break down the most common heat pump myths and explain the truth behind them – so you can make an informed decision with confidence.
Do heat pumps stop working when it’s cold outside?

Is installing a heat pump complicated and disruptive?
Heat pumps are quickly becoming one of the most popular heating solutions in the UK – and for good reason. They’re efficient, environmentally friendly, and suitable for a wide range of homes.
As we’ve covered, many of the concerns people have come down to outdated information or common misconceptions. When properly installed and set up, a heat pump can provide reliable, comfortable heating while helping to reduce both energy bills and carbon emissions.
If you’re considering making the switch, it’s worth exploring what options are available to you – including government-backed schemes that could significantly reduce the upfront cost or cover the cost completely.
