How Do Labour Costs for Extensions Vary and What Do I Need to Know? It’s a burning question for anyone looking to add that extra room or spacious open-plan living area. If you’ve glanced at quotes from builders, you know the numbers can bounce around like a rubber ball. For instance, a simple single-story extension could cost you anywhere from £1,200 to £2,500 per square meter, while a two-story project might push that to between £1,500 and £3,000. Why the difference? Factors like location, materials, and even the complexity of your design come into play, drastically shifting those labour costs.
Let’s put this into perspective. Imagine you’re in London, where everything seems more expensive. You might find builders charging as much as £250 a day for skilled tradespeople, while in a quieter part of the UK, rates could dip to around £150. And don’t forget about the trades involved—carpenters, electricians, and plasterers all come with their own rates that add up fast. If you opt for higher-end finishes, that can also hike up your labour costs significantly. It’s crucial to understand these variations before jumping into your renovation dreams.
