How Much Does a Loft Conversion Cost in Billericay?

If you live in Billericay and are thinking about converting your loft, one of the first questions you’ll have is: how much is this going to cost? While the price can vary depending on the type and complexity of the conversion, we’ve put together a helpful guide based on our experience working on lofts across Essex, including right here in Billericay.

Typical Loft Conversion Costs in Billericay

The average cost for a loft conversion in Billericay is between £35,000 and £60,000, depending on the type of conversion and the finish level you’re after.

Here’s a rough breakdown:

• Velux (Rooflight) Loft Conversion: £35,000–£40,000
• Dormer Loft Conversion: £40,000–£55,000
• L-Shaped Dormer: £50,000–£60,000+
• Hip-to-Gable Conversion: £45,000–£60,000+

Every home is different, so these are just starting points. Things like structural layout, roof shape, and access all affect the final cost.

What Affects the Price?

• Size of the loft: Bigger space = more materials and labour
• Type of conversion: Dormers and hip-to-gable conversions require more structural work
• Staircase design: A straight run is cheaper than a custom-turning stair
• Bathroom or en-suite: Plumbing and tiling add to the cost
• Finishes: Premium finishes or custom joinery will increase your spend

Is a Loft Conversion Worth It in Billericay?

Absolutely. With house prices rising and space at a premium, a well-built loft conversion can add up to 20% to your home’s value in this area. It’s also a great way to stay in the home you love while gaining that extra bedroom, home office, or living space.
