Thinking about buying a home?
It’s worth looking beyond the purchase price.
Many energy-efficient features that come as standard in a new home can cost thousands to add to an older property later on:
🏡 Low carbon heating (such as an air source heat pump): £3,000–£10,000*
🚗 EV charger: £1,000–£2,000
☀️ Solar panels: £5,000–£10,000
💨 Draught-proofing & improved ventilation: £100–£7,000
Retrofitting can also mean disruption, from upgrading pipework and radiators to installing new cabling or even strengthening your roof.
At Collaton Park, many of these energy-efficient features are already built in, helping you enjoy lower running costs and greater comfort from day one.
