In St Helens, a loft conversion typically ranges from £20,000 to £45,000 depending on the complexity and size of the project. Factors such as whether you need a dormer or Velux windows, as well as any necessary structural alterations, will influence the total cost. For example, a simple Velux conversion may cost around £20,000, while a more extensive dormer conversion can reach up to £45,000.

It’s essential to ensure that your builder has the relevant NICEIC certification, which indicates they are qualified for electrical work, especially if your loft conversion requires new wiring or lighting. Additionally, check that your builder is registered with FMB (Federation of Master Builders) for peace of mind regarding quality and adherence to building regulations.

If you're considering a loft conversion, it’s a worthwhile investment, as it can significantly increase your home's value and living space. Be sure to gather multiple quotes from local builders to find the best options suited to your needs.
