RENOVATION COSTS

Understand renovation costs before you start speaking to builders.

These figures are intended as an early planning guide. Every renovation is different, but understanding typical costs now can help you make better decisions later.

Typical project costs

Indicative planning figures for Ilkley and surrounding areas. Make the price range your starting point, then adjust for specification, access and complexity.

Single-storey extension

£2,200–£3,300

per m²

A broad construction allowance before VAT. Kitchens, large glazing and complex structural work can increase the total.

Whole-house renovation

£1,200–£2,000+

per m²

A useful starting range for substantial work to existing space, including VAT. Older or more complex homes may cost more.

Dormer loft conversion

£55,000–£80,000

A typical broad range, depending on roof structure, access, layout and the level of finish.

Kitchen renovation

£15,000–£40,000+

A practical range for many fitted kitchens. Bespoke cabinetry, premium appliances and structural changes can take the cost much higher.

Bathroom renovation

£5,000–£10,000+

A typical installed bathroom often begins around this level. Layout changes, tiling and premium fittings can add considerably.

Double-storey exstension

£2,500–£3,800

per m²

Provides extra living space across two floors. The final cost depends on the size, structural complexity and quality of the finished specification.

Remember the costs around the build

The construction price is not always the full project budget. Depending on the work, you may also need to allow for design and technical fees, statutory approvals, VAT and a contingency.

Professional fees

Often around 5–15%

The percentage depends on the service and level of involvement.

Contingency

Allow around 10–15%

Keep this separate for genuinely unexpected work.

VAT

Usually 20%

Most ordinary repair and improvement work is standard-rated.

A note for Ilkley and Wharfedale

These are broad UK planning figures rather than fixed local prices. Older stone properties, restricted access, conservation considerations and a higher specification can place an Ilkley project toward the upper end of a range.
