Kitchen Renovation FAQs
How long does a kitchen renovation take?
A standard kitchen renovation takes 2–4 weeks. Open-plan kitchen extensions take 6–14 weeks depending on structural work.
Do kitchen renovations need Building Regulations approval?
Replacing a kitchen like-for-like doesn't require approval. However, if you're moving gas or electrical services, or knocking through walls, Building Regulations apply.
What's the ROI on a kitchen renovation?
A well-specified kitchen renovation typically adds 5–10% to property value and significantly improves saleability. Open-plan kitchen-diners are consistently cited by estate agents as the single biggest value driver.
Should appliances be included in my budget?
Our estimate covers installation and fitting, not the appliances themselves. Budget an additional £2,000–£15,000+ for appliances depending on brand preferences.
