Renovating a house in North London can vary significantly depending on the size of the property, the level of finish and the scope of works involved.

As a general guide, most full house renovations in North London fall between £1,200 to £2,500 per square metre. High-end refurbishments in areas such as Hampstead or Highgate can exceed this depending on specification.

What affects the cost of a renovation?

Several key factors influence the overall cost:

Property size and layout
Structural alterations
Extensions or loft conversions
Quality of materials and finishes

Older properties often require more work, particularly when upgrading electrics, insulation and structural elements.
