What Affects the Cost?

Extension costs in Caldicot depend on project size, materials chosen (brick, render, timber cladding), foundation complexity, and site access. Building Regulation approval and structural engineer reports are essential and add £750–£1,400 upfront. Labour rates in Wales are typically lower than in South East England but competitive with major UK cities. Soil conditions, proximity to existing structures, and whether utilities need relocating all impact groundworks costs. Seasonal weather and supply chain delays can affect timescales and material pricing.

Money-Saving Tips

Get three detailed quotes from local Caldicot builders before committing. Plan extensions during winter months when builders have more availability and may negotiate. Use locally sourced materials where possible to reduce transport costs. Bundle other work (garage conversion, landscaping) with your extension for potential discounts.
