Questions
What factors affect rear extension costs in the UK?
Construction method, extension size, materials, site access, and location-specific factors like soil type and planning fees all influence costs.
Do I need planning permission for a rear extension?
Most single-storey extensions fall under permitted development, but two-storey extensions typically require formal planning approval.
How long does a rear extension take to build?
Single-storey extensions usually take 10-14 weeks, while two-storey projects typically require 16-20 weeks, depending on complexity.
What guarantees should I expect?
Reputable builders provide insurance-backed warranties, typically 10 years for structural work, and separate guarantees for components like windows.
Can I live at home during construction?
Most homeowners remain during single-storey builds but may consider temporary relocation for two-storey projects affecting essential rooms.
How do I choose a reliable contractor?
Check credentials with FMB or TrustMark, review past projects, verify insurance, and obtain multiple detailed quotes before deciding.
