Frequently asked questions

• What is the Energy Smart Collection at Twickenham Square?

  The Energy Smart Collection at Twickenham Square is a limited release of energy efficient 3 bedroom homes designed to use significantly less energy, produce fewer carbon emissions, and cost less to run than traditional second-hand homes.

  These homes are net zero in operation, meaning their everyday energy use results in a negative carbon impact, while delivering higher comfort and lower monthly bills.

• How are Energy Smart homes different from second-hand homes?

  Most second-hand homes were not built for modern energy prices, carbon targets, or comfort expectations.

  Energy Smart homes at Twickenham Square are designed with:

  • Advanced insulation and airtight construction
  • High-performance glazing
  • Significantly lower heat loss
  • Modern energy-efficient systems

  This results in lower energy bills, warmer interiors, and reduced environmental impact, compared to older homes.

• How much are energy bills in an Energy Smart home?

  A typical second-hand home costs around £111 per month in electricity.

  An Energy Smart 3 bedroom home at Twickenham Square is estimated to cost around £27 per month.

• Are these homes net zero in operation?

  Yes. The Energy Smart homes are net zero in operation, with a carbon impact of –0.41 tonnes per year.

  This means the home offsets more carbon than it produces during everyday living, unlike most second-hand homes which have a positive carbon footprint.

• What EPC rating do the Energy Smart homes have?

  The Energy Smart homes achieve:

  • EPC rating: B
  • Environmental Impact rating: A

  They are built well beyond current building regulations, with energy performance levels that align closely with Passivhaus principles, without being formally Passivhaus certified.

  In practical terms, this means:

  • Significantly lower energy demand
  • Excellent thermal performance
  • Reduced heat loss
  • Lower running costs compared to standard new builds and second-hand homes

  The focus is on real-world performance and everyday savings, rather than certification alone.
