The cost of hiring building contractors in London can vary significantly based on several factors, including the scope and complexity of your project, the materials used, and the contractor’s level of expertise. For example, residential building projects like home extensions or loft conversions typically start at around £1,200–£2,000 per square meter, depending on the design and finishes. Larger developments, such as new builds or commercial property projects, may cost upwards of £2,500 per square meter.
In addition to labor and material costs, it’s important to budget for additional expenses such as permits, structural repairs, or unforeseen issues that may arise during construction. Reputable contractors will provide a detailed breakdown of costs in their quotes, giving you a clear understanding of where your money is being spent. To get the most accurate estimate, provide contractors with as much detail as possible about your project, and don’t hesitate to ask questions to clarify any uncertainties.
