Understanding The Basics Of Loft Conversion Costs

Before diving into numbers, it helps to understand what makes up the cost. The cost to convert loft in Sussex depends on the type of conversion you choose and the level of work required.

  • Velux Conversions: Usually the most affordable option since they require minimal structural work.

  • Dormer Conversions: Add more space with a box-shaped extension but increase costs due to construction complexity.

  • Hip-To-Gable Conversions: Suitable for semi-detached homes with hipped roofs, but costs rise with roof alterations.

  • Mansard Conversions: The most extensive option, often requiring planning permission, resulting in higher overall costs.

Each type has its own price range for loft conversion in Sussex, and the finish you select, from basic to luxury, will also impact the total.

What Is The Average Loft Conversion Cost In Sussex?

On average, the loft conversion cost in Sussex ranges between £40,000 and £70,000, depending on the type of conversion and property size. However, costs can go higher for bespoke projects.

1. Price Per Square Metre In Sussex

Many homeowners ask about the price per m² in Sussex. Generally, you can expect to pay around £1,500–£2,500 per m². The variation depends on the complexity of the build, roofing changes, plumbing, electrics, and finishing details.

2. Average Build Cost

The average build cost for a standard dormer loft conversion in Sussex is approximately £45,000–£55,000, while more advanced designs such as mansard conversions can reach upwards of £70,000–£90,000.

Factors That Influence Loft Conversion Costs

Several elements affect the estimate price in Sussex for a loft conversion.

1. Size And Layout

The larger the space, the more materials and labour are required, leading to a higher total cost.

2. Type Of Conversion

A Velux conversion is significantly cheaper than a mansard or hip-to-gable, making type selection a crucial factor.

3. Structural Alterations

Reinforcing floors, adjusting roofing, or relocating water tanks can increase the cost considerably.

4. Planning And Permissions

If planning approval is necessary, costs rise due to additional design, application, and potential construction adjustments.

5. Internal Finishes

From flooring and lighting to en-suites, the level of finish directly influences the price range for loft conversion in Sussex.

6. Specialist Requirements

Features such as Juliet balconies, skylights, or integrated storage raise costs but add long-term value.

Budgeting requires more than knowing the average build cost. You should factor in:

  • Professional Design Fees: Some companies charge for design, but at Touchstone Lofts, design appointments worth £600 are free.

  • Contingency Funds: Always allow an extra 10–15% for unexpected costs.
