How You Pay

Projects from £25,000.
No large deposit.

Most kitchen projects fall between £25,000 and £55,000; larger builds range higher.

You never hand over a big sum up front and hope for the best. Instead, payment follows the work, in three clear steps.

01

Itemised proposal

Before anything is ordered, you receive a fully itemised cost proposal so you can see exactly where every pound goes. Every cost is agreed before work begins.

02

Weekly valuations

As the build progresses, we value the completed work each week and walk you through it, so you always know where the project and the budget stand.

03

Pay for signed-off work only

You are only ever billed for work that has been completed, inspected and signed off. No large upfront deposit, and no invoices for work that has not been done.

Grand Innovations Surrey did an outstanding job on our kitchen extension. This was a big project involving structural steelwork and a full redesign of our layout, and the team handled everything with real expertise. The quality of finish is superb, and the builders were friendly, tidy, and very considerate of our family routine. The result is better than we imagined, and we feel like we're living in a new home.
