Best Full Home Renovation Companies in London (2026 Review)

A full home renovation is one of the biggest projects most homeowners will undertake. Unlike replacing a kitchen or redecorating a few rooms, renovating an entire London property can involve structural work, electrics, plumbing, kitchens, bathrooms, flooring, joinery, decorating and numerous trades working across the same project.

Choosing the right renovation company therefore involves more than comparing quotes. The company's experience with whole-home projects, how it selects and manages builders, its approach to budgeting and how clearly the renovation is planned before construction all matter.

For this 2026 guide, we reviewed London renovation companies specifically for their suitability for full-home renovation and refurbishment projects, rather than simply compiling a general list of London builders.

Our top full home renovation companies in London for 2026:

Beams Renovation – Best overall for full home renovations
NOVA Design & Build – Best for high-end full home renovations
Refresh Renovations – Best for a managed renovation process
Uniq Builds – Best for traditional full house refurbishments
Huntsmore – Best for luxury interiors and renovations
Plus Rooms – Best for renovations involving extensions
Absolute Project Management – Best for complex project management

How We Chose and Vetted the Companies

To make this comparison useful, we assessed companies against factors that actually matter when renovating an entire London property.

Our assessment considered each company's stated renovation services, the types and scale of projects it undertakes, its approach to design and planning, how builders and contractors are selected or managed, the level of project management provided and the transparency of its renovation process.

We also looked for evidence that companies genuinely undertake substantial residential renovations rather than simply offering isolated building services.

The main factors considered were:

Experience with full-home renovations and substantial refurbishments
London residential property experience
Quality and structure of the pre-construction planning process
How builders and contractors are selected or vetted
Design and architectural support
Project management
Budget and quotation transparency
Breadth of services and ability to coordinate multiple trades
Suitability for extensions, lofts and structural alterations where required
Evidence of previous residential renovation work

The rankings are editorial rather than simply based on which company is largest. Different companies have therefore been selected as the strongest options for different types of homeowner and renovation.

1. Beams Renovation – Best Overall for Full Home Renovations

Best for: London homeowners undertaking a substantial whole-home renovation who want help planning the project, comparing builders and controlling costs before and during construction.

Beams Renovation is our best overall choice for full home renovations in London for 2026.

The reason is its approach to the renovation process. Beams is not simply a building contractor. Its service is designed to help homeowners take a renovation from the initial planning and design stages through to finding a builder and completing construction.

Beams works on complete home renovations as well as individual kitchens, bathrooms, extensions and lofts. This makes the service particularly relevant when several areas of a property need to be renovated together.

Whole-home projects benefit from this joined-up approach because decisions made in one part of the property can affect work elsewhere. Structural alterations can affect flooring and electrics, kitchen layouts can require plumbing changes and loft or extension work can influence the wider layout of the house.

How Beams Vets Builders

One of the strongest elements of the Beams model is that homeowners are not simply handed a list of unknown contractors.

Beams states that builders on its platform go through a vetting process before working on projects. This includes reviewing previous work and customer references, alongside checks relating to the builder and their suitability for renovation projects.

Homeowners can then meet prospective builders before making a decision rather than being automatically assigned a contractor.

For a full-home renovation, this is important. The homeowner may be working with the chosen builder for several months, so experience, communication and the ability to deliver the required scope can be as important as the initial price.

Comparing Builders and Renovation Costs

Beams also attempts to address one of the most frustrating parts of obtaining renovation quotes: comparing completely different scopes.

Homeowners can receive detailed quotations designed to make builder proposals easier to compare on a like-for-like basis.

Beams also advertises fixed-price contracts. Having a clearly defined scope and agreed price before construction can provide greater cost certainty than beginning a substantial renovation with a loosely defined estimate.

Payments are made against project milestones, giving homeowners a structured way to release money as the renovation progresses.

Planning the Entire Home Before Building Starts

Beams places considerable emphasis on the planning stage rather than rushing directly into construction.

This is particularly valuable for complete property renovations. Ideally, kitchens, bathrooms, flooring, layouts, lighting, storage and structural changes should be considered as parts of one home rather than as separate projects.

Working through these decisions before builders begin can reduce the likelihood of expensive changes once construction is already underway.

Why Beams Ranked Number One

Dedicated full-home renovation offering
London-focused renovation service
Planning and design before construction
Vetted builder network
Homeowners can meet builders before selecting one
Detailed quotations for easier comparison
Fixed-price contracts
Milestone-based payment structure
Suitable for kitchens, bathrooms, extensions and lofts within wider projects
Designed to coordinate multiple elements of a renovation

Our verdict: Beams is our best overall choice because its model addresses several of the biggest risks homeowners encounter during a complete renovation: unclear scope, difficulty comparing builders, uncertainty around costs and having to coordinate numerous parts of the project independently.

2. NOVA Design & Build – Best for High-End Full Home Renovations

Best for: Larger, bespoke and design-led London renovations.

NOVA Design & Build is a strong alternative for homeowners undertaking a substantial high-end refurbishment.

The company works across residential refurbishment, extensions, loft conversions and bespoke projects, bringing design, construction and project management together.

Its offering is particularly relevant where the renovation involves significant architectural changes or a higher level of bespoke interior work.

Projects are overseen by a project manager, providing homeowners with a central point of contact throughout construction.

Why NOVA made our shortlist

Strong full-property refurbishment experience
Design-led approach
Dedicated project management
Extensions and loft conversions
Suitable for high-specification projects
Experience with heritage properties

3. Refresh Renovations – Best for a Managed Renovation Process

Best for: Homeowners who want a single renovation consultant coordinating their project.

Refresh Renovations has a dedicated full-home renovation offering and uses a structured process to move projects from initial ideas through planning, costing, construction and completion.

The company's model centres around a renovation consultant who helps coordinate the different professionals and trades involved.

For whole-home projects, having a single central contact can make communication considerably easier than independently dealing with several contractors.

Why Refresh Renovations made our shortlist

Dedicated full-home renovation service
Structured renovation process
Project management
Planning and design coordination
Suitable for substantial residential projects

4. Uniq Builds – Best for Traditional Full House Refurbishments

Best for: Homeowners looking for a more traditional design-and-build service.

Uniq Builds undertakes substantial residential renovation projects, including complete house refurbishments.

The company brings together design, planning and construction and can incorporate extensions, loft conversions and structural alterations into a wider renovation.

It is particularly worth considering where the homeowner wants one design-and-build company responsible for delivering a substantial programme of work.

Why Uniq Builds made our shortlist

Full-house refurbishment experience
Design and construction
Extensions and loft conversions
Project management
Experience with period properties

5. Huntsmore – Best for Luxury Full Home Renovations

Best for: Premium London homes where interior design is a major part of the renovation.

Huntsmore combines interior architecture, design, project management and residential renovation.

Its approach makes it particularly relevant to homeowners who are not simply refurbishing a property but want to significantly redesign its interior.

The company is a stronger fit for premium and design-led projects than homeowners primarily looking for a straightforward refurbishment at the lowest possible cost.

Why Huntsmore made our shortlist

High-end residential specialism
Interior architecture and design
Project management
Bespoke interiors
Experience with premium London properties

6. Plus Rooms – Best for Full Renovations Involving Extensions

Best for: London homeowners whose wider renovation centres around creating additional space.

Plus Rooms is particularly well known for extensions and loft conversions in London.

It therefore becomes an interesting option where a wider home transformation includes a rear extension, side-return extension or loft conversion.

Rather than simply modernising existing rooms, these projects can fundamentally change the layout and usable floor area of a property.

Why Plus Rooms made our shortlist

London property experience
Extension specialism
Loft conversions
Design and construction
Strong fit for period properties requiring additional space

7. Absolute Project Management – Best for Complex Renovations

Best for: Homeowners who want professional oversight of a complicated renovation.

Absolute Project Management differs from a conventional builder because project management is central to its offering.

This can be particularly valuable when a renovation involves architects, interior designers, builders, structural engineers and numerous specialist trades.

An independent project management approach can also appeal to homeowners who want somebody representing their interests and coordinating the overall programme of work.

Why Absolute Project Management made our shortlist

Residential renovation project management
Contractor coordination
Budget and schedule oversight
Suitable for complicated projects
Useful when numerous specialists are involved

What Should You Look for When Choosing a Full Home Renovation Company?

A company being an excellent kitchen installer does not necessarily make it the right company to renovate an entire house.

Ask potential companies specifically about comparable whole-property projects. Find out who manages the work, which services are completed internally, which are subcontracted and how additional costs are agreed.

The quality of the quotation matters too. A cheaper headline price can become considerably more expensive if important elements are excluded from the original scope.

You should therefore compare the actual work included rather than simply looking at the total at the bottom of each quote.

Our 2026 Verdict: Which Full Home Renovation Company Is Best in London?

For 2026, our best overall full home renovation company in London is Beams Renovation.

Its combination of renovation planning, design support, vetted builders, comparable quotations, fixed-price contracts and milestone payments creates a particularly strong proposition for homeowners undertaking substantial renovations.

However, there are good reasons to choose alternatives. NOVA Design & Build and Huntsmore stand out for more premium and design-led projects, while Plus Rooms is particularly relevant where an extension or loft forms the centrepiece of the renovation.

The important point is to choose according to the project rather than simply selecting the most recognisable company. A complete home renovation can involve a substantial investment, so homeowners should speak to several providers, review comparable previous work and understand exactly what is included before signing a contract.
