How Much Does a Garage Conversion Cost in the UK?
Providing an exact figure is impossible without assessing the specific project, but we can give you a realistic and helpful guide to budgeting. Costs are influenced by the size of your garage, your location in the UK, and the specification of the finish you desire. Remember, the cheapest quote is rarely the best. A professional job that complies with all regulations is an investment that will pay dividends for years to come.
Average Cost for a Single Garage Conversion
For a standard single garage (approximately 15m²), you can expect the cost to be in the range of £10,000 to £20,000. This typical budget would cover the full conversion process: structural work, new insulated floor, full insulation of walls and ceiling, basic electrics, a new window, plastering, and new skirting boards, leaving you with a finished "shell" ready for decorating and flooring.
Average Cost for a Double Garage Conversion
Converting a larger double garage (approximately 30m²) naturally involves more materials and labour. A typical budget for a double garage conversion would fall between £20,000 and £35,000. This could create a substantial new living space, potentially large enough for a living room and kitchen, or multiple rooms like a bedroom and an office.
Factors That Influence the Final Cost
Your final quotation will depend on several key variables. It's important to discuss these with your specialist to understand where your money is going.
- Location: Labour and material costs are typically higher in London and the South East compared to other parts of the UK.
- Structural Condition: If the existing foundations need reinforcing or the roof structure requires significant repair, this will add to the overall cost.
- Intended Use: A simple home office will be at the lower end of the cost scale. Converting the space into a kitchen or a bathroom with extensive plumbing, waste connections, and higher-spec electrics will significantly increase the budget.
- Quality of Materials and Finishes: The choices you make have a big impact. High-end aluminium bifold doors will cost more than a standard uPVC window. Likewise, underfloor heating, bespoke joinery, and premium flooring will all affect the final price.
- The Professional Team: The quote should cover all labour, including specialist tradespeople like certified electricians and Gas Safe registered engineers where required.
