Greener Homes

Plaid believe that all homes, offices and public buildings should have the highest level of energy efficiency.

New Builds

We would plan houses in a way which will accommodate seamless transfer to new technologies. We would pursue the roll-out of energy positive houses which are capable of exporting surplus energy to the electricity grid.

In planning new homes, we would ban the use of fossil fuel energy and require all to be highly energy efficient.


We would create a long term energy efficiency infrastructure plan to retrofit the entire Welsh housing stock to higher environmental standards over the next 30 years. This would contribute to ending fuel poverty and the associated ‘excess deaths’ in winter.

Plaid have a target of retrofitting every home by 2050, this programme will deliver 20 per cent efficiency savings across the Welsh domestic stock.

Heating by electricity and heat pumps would be our priority and we would therefore develop a major programme of installing heat pumps, prioritising off-grid homes.  We would offer every home a free energy audit and recommendations on a conversion plan.
