You don’t renovate a home like this to spend money You do it to protect it
In London, renovating isn’t just about comfort or keeping up with trends. It’s about protecting your home — and your investment.
Whether it’s a Georgian townhouse in Chelsea, a Victorian terrace in Hampstead, or a sleek apartment in Marylebone, every decision you make affects both how you live and how much your property is worth in the long run.
So, what does a full renovation actually cost in 2025 — and where should you focus your budget to make it count?
Average Renovation Costs in London (2025)
The cost of a full-house renovation in London usually falls between £250,000 and £700,000+, depending on the size, condition, and level of finish.
Type of Renovation | Typical Range | What’s Included |
|---|---|---|
Light renovation | £150K – £250K | Cosmetic updates like new flooring, lighting, and a simple kitchen or bathroom refresh |
Full renovation | £250K – £500K | Structural changes, new plumbing and electrics, bespoke joinery, kitchen, bathrooms, and lighting |
Luxury or listed renovation | £500K – £1M+ | Heritage restoration, bespoke materials, design-led lighting, home automation, and premium finishes |
What Can Affect the Cost
Location & Access – Central London projects can be tricky with parking restrictions, limited access, and listed-building rules.
Structural Work – Moving walls or adding steel supports can increase your budget by 20-30%.
Finishes & Materials – Natural stone, solid wood, and custom joinery cost more, but they elevate the entire home.
Project Management – A professional design-build team keeps things organised and helps avoid delays (which often cost more in the end).
Planning & Permissions – Listed or conservation-area homes can take longer to approve, adding extra consultant fees.
Why Design-Build Can Save You Money (Even If It Costs More Up Front)
Traditional projects often involve separate architects, designers, and builders which can lead to miscommunication and expensive rework.
A design-build setup, like Accanto Interiors, brings everything under one roof: design, planning, and construction all handled by one team.
That means:
- Fewer mistakes and delays
- One point of contact throughout
- A smoother process overall
In most cases, clients actually save 10-20% compared to managing separate teams and get a better-quality result.
Where to Spend and Where to Save
Example: West London Townhouse
One of our clients in Chiswick spent £420,000 renovating a four-storey townhouse.
By reworking the layout, adding bespoke storage, and updating the lighting design, the property’s value rose by £750,000 within two years.
The difference wasn’t about spending more – it was about making smarter design decisions.
The Takeaway
Renovating isn’t just about creating a showpiece home – it’s about designing something that adds real, lasting value.
In London, a well-planned renovation protects your wealth as much as it improves your lifestyle.
So plan carefully, and work with a team who will treat your home and your investment like their own.
