Kitchen Renovation Planning Checklist

Decide what stays and what goes before you call contractors

A kitchen renovation quote only becomes meaningful once the scope is specific. Before you start collecting prices, map the existing kitchen and mark every element you plan to keep, replace, or relocate: cabinets, countertops, backsplash, sink, hob, hood, fridge cavity, island, and lighting. Ambiguous scope is one of the biggest reasons two contractors quote very different prices for what sounds like the same job.

Keeping or relocating plumbing and electrical points materially changes cost. List whether any water points, gas points, or electrical sockets need to move, and by how many metres if you can measure it.

Check what needs an HDB permit before you scope

For HDB flats, some works need a renovation permit before they can start, and others must simply follow HDB's guidelines. HDB requires a permit for works that affect structural integrity or public safety, such as demolishing or hacking walls, while works like overlaying floor tiles, electrical wiring, or carpentry generally do not need one. All demolition and hacking of walls needs HDB's prior written approval.

Two rules shape the plan for HDB kitchens. First, you must engage a contractor listed in HDB's Directory of Renovation Contractors, even for works that do not need a permit. Second, renovation is only allowed within set hours: general works between 9am and 6pm on weekdays and Saturdays, and noisy works such as wall hacking and tile cutting between 9am and 5pm on weekdays only, with none on Sundays and public holidays. Build these constraints into your scope and timeline before collecting quotes.

Settle material expectations before the quote

Material choices dominate the final kitchen bill. Quartz, sintered stone, and laminate countertops sit at different price points and have different lead times. Cabinet carcass material (plywood, melamine, HDF) affects longevity and price. Door finishes (laminate, HPL, PET, solid wood) are not interchangeable when you are comparing quotes.

Put your baseline material assumptions in writing before asking for a quote, so every contractor is pricing the same thing. This is also what lets you negotiate confidently: if one contractor is cheaper, you can see exactly which material assumption they swapped.

Lock your appliance sizes first

Appliance cut-outs drive cabinetry. If you are replacing appliances, buy or confirm the exact model numbers before finalising cabinetry. A 60 cm dishwasher and a 45 cm dishwasher are not minor-change items; rework at installation is expensive and delays the whole project.

Plan around two move-in realities

First: kitchens are used daily, and small decisions compound over years. The work triangle (sink, hob, fridge), drawer versus door storage, socket location, and lighting are the things you will feel every day. Second: kitchens often generate variation requests during work, because site conditions such as pipe routing and wall squareness only emerge once demolition happens. A milestone-based payment structure, agreed in writing, gives both sides a fair way to handle those changes.
