Kitchen Renovation Cost Guide for Hampstead & NW London

The kitchen is typically the most expensive room in a house to renovate, and in Hampstead, where homeowner expectations and property values are both high, kitchen costs can be substantial. Whether you are refreshing an existing layout or creating an entirely new open-plan kitchen-diner as part of an extension, this guide will help you understand the indicative costs involved.

All cost figures are indicative estimates. We are an information and matching service and do not carry out building work. Actual costs will depend on your specific requirements, specification, and choice of materials. Always obtain detailed quotations.

Indicative Kitchen Costs

These figures cover the kitchen itself — units, worktops, appliances, and installation. If your kitchen renovation involves structural work such as removing walls, building an extension, or lowering a floor, those costs are additional. See our extension cost guide for structural work estimates.

What Drives Kitchen Costs

Cabinetry

Cabinetry is the single largest cost in most kitchen projects. Off-the-shelf flat-pack kitchens from major retailers can be installed from around £5,000–£10,000. Semi-custom ranges from mid-market suppliers sit in the £10,000–£25,000 range. Bespoke, handmade kitchen furniture — popular in Hampstead's period properties — typically starts at £25,000 and can exceed £60,000 for a large kitchen.

Worktops

• Laminate: £500–£1,500
• Solid wood: £1,000–£3,000
• Quartz composite: £2,000–£5,000
• Natural stone (granite, marble): £3,000–£8,000+

Appliances

A full suite of appliances (oven, hob, extractor, fridge-freezer, dishwasher) ranges from £2,000 for standard brands to £15,000+ for premium manufacturers like Gaggenau, Miele, or Sub-Zero.

Plumbing and Electrics

Reconfiguring plumbing and electrics to suit a new kitchen layout typically costs £2,000–£5,000. If you are moving the kitchen to a new location within the property, expect higher costs for drainage runs and electrical circuits.

Kitchen Extensions

Many Hampstead homeowners combine a kitchen renovation with a rear extension or side return to create a larger, open-plan kitchen-living space. This is often the most transformative and valuable improvement you can make to a period terrace. The combined cost of an extension plus kitchen fit-out typically ranges from £70,000 to £150,000+ depending on size and specification.

Period Kitchen Considerations

Hampstead's period properties present specific considerations for kitchen design:

• Uneven floors and walls — period properties rarely have level surfaces, which complicates installation and can increase costs by 10–15%.
• Heritage features — cornicing, skirting, and original flooring may need to be preserved or replicated.
• Ventilation — older properties may require additional ventilation solutions to meet building regulations.

Our period property renovation costs guide explains these factors in more detail.

Professional Support

An experienced kitchen designer or architect can help you maximise your layout, select appropriate materials, and manage the installation. For projects that involve structural work or planning considerations, an architect is particularly valuable. Architect Hampstead connects homeowners with local architects experienced in kitchen and extension projects.

If your kitchen project forms part of a larger renovation that requires planning permission, Planning Hampstead can provide guidance on Camden Council requirements and conservation area constraints.

Tips for Managing Kitchen Costs

1. Set a clear budget early — decide your maximum spend before visiting showrooms.
2. Prioritise what matters — invest in the elements you will use and see most (worktops, cabinet fronts, primary appliances) and save on less visible elements.
3. Consider value engineering — our value engineering guide explains how to reduce costs without compromising quality.
4. Get multiple quotes — for both supply and installation, compare at least three options.
