The cost for a house extension in Hackney can vary significantly based on size and complexity. On average, you can expect to pay around £1,500–£2,200 per square meter for a high-quality extension. For a typical 20 square meter extension, this could amount to approximately £30,000–£44,000. Factors such as planning permissions, design costs, and materials can also influence the total price.

It's important to engage professionals who are NICEIC or FMB certified to ensure that the work complies with local building regulations and standards. Additionally, if your extension involves plumbing or gas installation, make sure to hire contractors who are Gas Safe registered.
