Are you aware of the Latest U-value Regulations?

This blog will investigate the new changes to building regulations, therefore ensuring you are aware of the Latest U-value Regulations!

Why have these regulations changed?

Building regulations have changed as currently, heating and powering buildings in the UK account for 40% of our total energy usage. So making buildings more efficient will reduce demand for energy, as well as save homeowners money on energy bills.

Therefore increasing the level of insulation in roofs, walls and floors will further help to achieve the U-values. This means with lower U-values in place, there will be a reduction in the requirement for as much heat and power in homes.

As part of the Department Business, Energy & Industrial Strategy, they are aiming to half all energy usage by 2030. Their mission for this can be found at the following link – Click Here!

When did these changes come into place?

The Amendment Regulations and accompanying Approved Documents L: Volumes 1 and 2 come into force on 15 June 2022.

However, these changes will not apply to plans deposited to a local authority before this date, and started prior to 15 June 2023.
