Finding a residential refurbishment contractor with transparent pricing and direct project oversight is difficult for London homeowners. Most contractors hide pricing, lack clear single points of contact, or do not publish independent reviews for budget planning. You can compare quality, pricing approach, and project management across six alternative providers and match one to your home improvement goals without guesswork.
Table of Contents
Tenen LTD
At a Glance
The company director personally oversees every project from the initial survey to final handover. Tenenltd was established in 2006 and operates across central and west London neighbourhoods such as Chelsea, Kensington, Fulham, Hammersmith, Chiswick, Notting Hill, Hampstead, and Westminster. Projects cover full refurbishments, loft conversions, extensions, and commercial refurbishment.
Core Features
Tenenltd combines design, planning, and construction so a single contractor carries projects through every stage. The firm issues transparent, itemised quotes with no hidden costs and keeps project management and construction teams internal to maintain consistency. Director involvement on each job aims to keep communication direct and reduce approval delays.
Key Differentiator
The standout trait is personal oversight by the director on every project, which gives clients one named decision maker and a single point of contact. That structure reduces the number of intermediate managers and keeps quality checks close to the job. For London homeowners who value direct communication, this model changes how choices and defects are resolved on site.
Pros
Tenenltd advertises transparent pricing and detailed quotes, which helps homeowners compare scope and costs before committing. According to the company, many projects finish ahead of schedule, and that claim underpins their promise of reliable timelines. The director�s personal involvement supports direct reporting and faster decisions on changes. Their experience across full refurbishments, loft conversions, extensions, and commercial work means the team can handle complex planning and construction phases without bringing in multiple contractors.
Cons
Limited online information about specific service packages or pricing. You will usually need a site survey for a bespoke quote.
Who It’s For
Homeowners in London seeking high-quality refurbishment or an extension who prefer a single point of contact will find Tenenltd a close match. Property investors wanting a reliable contractor to add value through renovations will also benefit. Commercial landlords with smaller fit-out or refurbishment needs can use the same construction and planning expertise.
Unique Value Proposition
Director-led oversight gives you a named decision maker who signs off on workmanship and client updates. That model can cut down on miscommunication between design, site teams, and subcontractors and keeps responsibility clearly assigned. For projects in tight London terraces, this clarity helps maintain timelines and quality.
Real World Use Case
A couple in Chelsea commissioned Tenenltd to refurbish a Victorian mid-terrace property. The director managed the initial survey, arranged planning inputs, and supervised day-to-day works until handover. The single point of contact simplified decisions on finishes and saved time when design changes were needed.
Pricing
Pricing is not publicly listed and appears to be bespoke, with quotes tailored to project scope and site conditions. Tenenltd advertises transparent, itemised quotes with no hidden costs, so you can expect a detailed estimate after a site visit. For accurate budgeting, request a fixed-fee quotation following a survey.

NU Projects
At a Glance
NU Projects uses in-house quantity surveyors and a build cost calculator validated by RICS/BCIS to support estimates. The company combines design, project management, and construction under one contract for high-end homes. Its marketing highlights a proprietary AI powered management tool called “Mission Control” to track costs and timelines.
Core Features
An in house team handles architecture, interior design, and project management while an elite construction network delivers build work. The offering includes cost estimation and control supported by the build cost calculator, and quantity surveyors who refine budgets and change control. The vendor also advertises Mission Control, an AI powered management system that aims to centralise reporting and site oversight.
Key Differentiator
NU Projects brings design and build together under one contract so you deal with a single team from concept to handover. That integrated model sits alongside an in house quantity surveying function to manage cost risk at every stage. The partnership between the in house team and the Mission Control software creates a stronger link between design decisions and their budgetary impact.
Pros
You get a single point of contact for design, procurement, and construction which simplifies communication on complex refurbishments. The presence of in house quantity surveyors supports clearer cost control and change management during works. Dedicated project managers for each scheme mean staff continuity on site, and the vendor claims the AI powered tool improves oversight and reporting.
Cons
Public information is thin. The website lacks detailed service breakdowns and day to day process descriptions.
There are no third party reviews or independent testimonials readily available to verify performance.
Pricing and standard package details are not published, so you must request a bespoke proposal to see costs.
When It May Not Fit
If you want transparent, published pricing or readily available independent reviews, this provider is not the best match. If your scheme is modest in scale or budget you may prefer a contractor with clear small project packages. Also, clients who prioritise exhaustive online documentation will find the website content limited.
Who It’s For
You are a homeowner in Prime London who needs a high end renovation and prefers a single team to manage design and build. You value in house cost control and direct access to surveyors and project managers. You expect tailored proposals rather than off the shelf packages.
Real World Use Case
A homeowner in Chelsea commissions a full flat refurbishment. NU Projects supplies architects and interior designers, prepares a RICS aligned budget, and manages contractors on site. The team uses Mission Control to report progress and cost changes back to the client at agreed intervals.
Pricing
Pricing is not published and the vendor lists pricing as not applicable for public display. Projects are quoted on a bespoke basis after initial brief and survey. Expect to contact the team for a tailored estimate and schedule.

Red Box London
At a Glance
Established in 2005, Red Box London reports steady client referrals in Fulham and neighbouring boroughs. The company focuses on loft conversions, kitchen and bathroom refits, house extensions, painting, decorating, and ongoing maintenance for domestic properties. Memberships with trade associations appear frequently in its marketing and are central to how it positions quality.
Core Features
Red Box London offers property renovation and refurbishment, loft and house extensions, and kitchen and bathroom fitting, together with painting, decorating, and general home maintenance. Projects range from small repairs to full refurbishments and the company assigns carpenters, joiners, fitters, decorators, and project managers as required. The team handles on site coordination of trades people for staged renovations.
Key Differentiator
The most distinctive feature is a long standing local reputation built since 2005, supported by client referrals and trade association membership. That reputation makes the firm a clearer match for homeowners who prefer contractors with an established West London portfolio and visible credentials.
Pros
The firm benefits from a referral driven pipeline that keeps lead quality local and repeatable. That pipeline pairs with experienced trades people including carpenters, joiners, fitters, decorators, and project managers who work on site. Trade association membership such as Federation of Master Builders and Painting and Decorating Association gives a public signal of standards and professional accountability.
Cons
No specific cons reported in third party reviews or publicly available feedback.
Limited information on pricing or detailed project timelines in company content.
No mention of online project management or digital collaboration tools for client access.
When It May Not Fit
If you require a published price list or online quoting portal, Red Box London may not match your needs. The firm does not promote a client facing project portal or real time task tracking. Clients who prioritise remote collaboration and live status updates should look for a contractor with stronger digital tools.
Who It’s For
Homeowners in Fulham and surrounding West London boroughs who value an experienced local team will find this firm suitable. Property investors seeking small to medium refurbishments and extensions will also find the local portfolio relevant. It appeals to people who prefer referral driven contractors and visible trade association membership.
Real World Use Case
A Fulham homeowner plans a kitchen extension and loft renovation and wants a single contractor to manage trades on site. Red Box London would provide initial site visits, a scoped proposal, and coordination of carpentry, plastering, and decoration through a named project manager. That approach keeps on site contacts consolidated for the duration of the build.
Pricing
Pricing is listed as not applicable and the entry is informational only. Red Box London does not publish standard rates online. You must request a bespoke quote to receive cost estimates and project timelines for your specific works.

House Renovation
At a Glance
Listed building restoration sits alongside international luxury villa projects in the company portfolio. The practice keeps full aesthetic and technical control over each project from initial sketches through to handover. That approach makes them a clear choice for owners who need heritage sensitivity and high-end finishes.
Core Features
The studio combines architecture, interior design, and construction under one team to manage every stage of a renovation. Project leads take responsibility for planning approvals, heritage consents, and contractor coordination while designers develop bespoke interiors. Specialist work covers basement conversions, listed property refurbishment, and bespoke villas overseas.
Key Differentiator
Integrated project delivery from concept to completion with an in-house team distinguishes the practice. That model reduces handoffs between consultants and contractors and keeps decision making centralised. The focus on heritage and bespoke high-end work gives them a narrow but deep expertise.
Pros
The firm offers true full service, running design, approvals, procurement, and site delivery under one contract. Their experience with listed and period buildings means they understand conservation requirements and traditional materials. International villa projects in the portfolio show an ability to adapt quality standards to different regulatory environments while maintaining client communication and clear project management processes.
Cons
No independent third party reviews are publicly available, which limits outside validation.
Price is not listed and the luxury positioning suggests a premium cost profile for most projects.
Public information on typical project durations and milestone timings is limited, making early programme planning harder.
When It May Not Fit
Clients on a modest budget will find this practice unsuitable because the emphasis is on bespoke finishes and specialist crafts. Those needing standard refurbishment work or simple cosmetic updates will likely pay more than needed. Developers seeking transparent, published package pricing may prefer firms with clearer public rates.
Who It’s For
Privately wealthy homeowners and developers who own period or listed properties in London and internationally. Clients who want a single team to manage architectural design, interior fit out, and construction will benefit most. People who accept premium fees in exchange for specialist craft and heritage experience will find a good match.
Real World Use Case
A London owner of a listed mansion commissions the studio to restore original joinery, replace services sympathetically, and insert contemporary luxury finishes. The team handles heritage consent, sources reclaimed materials, and oversees interior design to maintain period character. The result is a preserved exterior with modern, bespoke interiors delivered by one delivery team.
Pricing
Pricing is not publicly specified. Fees are likely premium because work is bespoke, specialist, and aimed at high net worth clients. Prospective clients should request a detailed estimate and a sample programme early in the enquiry process.

Mayer Construction
At a Glance
Work includes Grade II listed buildings and mansions across prime London addresses. Mayer Construction covers design coordination through to post construction aftercare and handles complex engineering requirements. The firm trades on a reputation for meticulous craftsmanship and attention to conservation detail.
Core Features
Mayer Construction offers full project management from initial design through to post construction aftercare, working closely with architects and interior designers. The company handles heritage and conservation requirements alongside modern engineering upgrades, and assembles specialist subcontractors for bespoke scopes. Sustainability and attention to finish form part of routine quality control on its London projects.
Key Differentiator
Mayer Construction specialises in heritage sensitive, high end residential schemes where conservation rules and bespoke engineering collide. That focus on meticulous craft and conservation-aware problem solving sets it apart from general contractors working on standard refurbishments.
Pros
Deep experience with high end residential and heritage projects gives Mayer Construction the knowledge to navigate listed building consents and specialist structural challenges. The team’s collaborative approach with leading architects and designers keeps design intent intact while solving on site problems. Comprehensive aftercare reduces snagging headaches and helps preserve finishes after handover.
Cons
Limited publicly available pricing or cost transparency makes early budget planning difficult for homeowners.
No third party reviews are readily visible to validate client experience or delivery history.
Focus on bespoke, luxury work implies project costs that are likely above mid market budgets.
When It May Not Fit
Mayer Construction is not the right match for budget conscious homeowners or straightforward, small scale works. Clients seeking quick, low cost refurbishments will find the procurement and team assembly here more complex than needed. The limited public reviews also make independent reference checking harder for risk averse buyers.
Who It’s For
This firm suits affluent homeowners, architects, and interior designers commissioning complex restorations or full rebuilds in London. It fits owners of period properties who require sensitive restoration and bespoke finishes. Developers with prime central London plots that demand conservation expertise will also find the offering relevant.
Real World Use Case
A Kensington owner commissions Mayer Construction to rebuild a Grade II listed townhouse with modern services and bespoke joinery. The team coordinates structural engineers, conservation officers, and specialist joiners to preserve historic fabric while adding modern amenities. Post construction aftercare addresses settling and finish maintenance for the new works.
Pricing
Pricing is not published and the listing notes “Not applicable — informational only”. Mayer Construction operates on bespoke quotes tailored to scope and heritage requirements. Contacting the company for a site visit and a formal estimate is the only way to get realistic budget figures.

Corinth Contractors
At a Glance
Corinth Contractors reports over 150 successful projects in London and surrounding areas. The company pairs design and build capabilities with end-to-end project management and offers structural warranties for completed works. That combination targets homeowners who want a single point of contact from concept to handover.
Core Features
Their core offering combines design and build with architectural collaboration, covering planning, cost estimation, procurement, and construction. The team delivers extensions, loft conversions, new build work, and full refurbishments while coordinating with award-winning architects and interior designers. Post-project support and structural warranties feature alongside traditional site supervision and qualified tradesmen.
Key Differentiator
Corinth Contractors positions itself on a complete client-focused approach that links experienced project managers with architects and skilled tradesmen. That project count supports their claim of practical experience on London projects. The firm emphasises hands-on coordination so clients deal with one team rather than multiple disconnected contractors.
Pros
Their portfolio gives visible practical experience working on London homes, and that portfolio underpins confidence when planning complex extensions or conversions. Collaboration with award-winning architects and interior designers helps deliver considered layouts and finish choices that match high-end expectations. The company supplies structural warranties and post-project support, and a dedicated team of qualified tradesmen and project managers keeps schedules and quality under direct control.
Cons
No third-party reviews or ratings are publicly listed, so independent customer feedback is not available.
Pricing and specific project costs are not published, making early budget comparisons difficult.
The company does not advertise an online client portal or digital project-tracking tools for remote updates.
When It May Not Fit
If you want an online dashboard for daily progress updates, Corinth Contractors may not match that digital expectation. Clients who need transparent, published price lists for quick comparison will find information limited. Homeowners who rely on publicly visible third-party ratings for shortlist decisions will have less evidence to review.
Who It’s For
This firm suits London homeowners who want a single supplier for design, build, and project management and value workmanship and architectural collaboration. It fits owners planning extensions, loft conversions, new builds, or full refurbishments who prefer direct oversight by project managers. If you prioritise warranties and a hands-on trades team, this is a practical match.
Real World Use Case
A London family commissions Corinth Contractors to design and build a rear extension and convert the loft into two bedrooms. Corinth manages the planning application, hires structural engineers, coordinates the architect, and runs the site works through to completion. The family receives a structural warranty and post-project support once the handover is complete.
Pricing
Pricing is not published on the website. The company lists services and project types but asks clients to request bespoke estimates. Contacting Corinth Contractors is the only way to obtain a detailed cost breakdown for your project.

Comparison of alternatives
For homeowners valuing direct communication and centralised responsibility, tenenltd.co.uk provides a superior service model. Below, we examine key differences across alternative contractors to support informed decisions.
Communication and Project Responsibility
Red Box London distinguishes itself through a long-standing local presence and direct trades’ coordination. Its client referral network suggests reliability for homeowners within West London. In contrast, NU Projects benefits from integrated quantity surveying tools for superior cost control and risk management during design changes. These capabilities surpass tenenltd.co.uk in managing complex budgets but lack the singular oversight appeal of its director-led approach.
Expertise in Heritage Buildings and Specialised Craftsmanship
House Renovation is in handling listed properties and heritage-sensitive refurbishments. Its thorough understanding of traditional conservation requirements provides a clear advantage for owners of period homes. Similarly, Mayer Construction focuses on bespoke artisanal features and engineering precision, lending it suitability to technically demanding restorations where structural challenges are significant.
Best fit
