Popular Services in Kensington
Property renovation is the primary service in Kensington, with full refurbishments of period townhouses and mansion flats that often involve structural alterations, rewiring, replumbing, and high-specification kitchen and bathroom installations. Bathroom fitting projects in Kensington are at the luxury end, with clients specifying natural stone, bespoke vanity units, and underfloor heating throughout. Painting and decorating work tends to involve specialist finishes and heritage colours appropriate to the period of the property.
Planning & Building Control in Kensington
Kensington falls under the Royal Borough of Kensington and Chelsea, which has some of the most stringent planning policies in London. Almost the entire borough is covered by conservation areas, and many properties are Grade I or Grade II listed. Listed Building Consent is required for virtually all internal and external works to listed properties. The council has specific policies on basement development, requiring Basement Impact Assessments and Construction Traffic Management Plans. We work with heritage consultants and structural engineers experienced in RBKC requirements.
Kensington Property Insights
Kensington properties are typically of exceptional build quality, with thick solid brick or stucco walls, high ceilings (3.0-3.5 metres), and ornate original features including plasterwork, ceiling roses, cornicing, fireplaces, and timber panelling. Preserving and restoring these features is essential both for planning compliance and for maintaining property value. The London Clay subsoil requires careful management for any below-ground work, and the concentration of basement conversions in the area means the water table has been affected in some streets.
Common Projects in Kensington
Full property renovation on a stucco-fronted townhouse
The signature Kensington project. Renovation of a Victorian or Georgian townhouse typically involves structural opening-up of the ground floor, rewiring to BS 7671, replumbing, full insulation upgrade where listed status allows, new kitchen and bathrooms throughout, lime-based plaster repairs on original walls, and complete decoration to luxury specification. Cost is £400,000-£1,500,000 depending on size, listed status, and specification. Build time 28-40 weeks with a single project manager and conservation-specialist architect. Listed Building Consent is required for almost all works and runs in parallel with planning at the Royal Borough.
Luxury bathroom renovation
Kensington bathrooms are renovated to luxury specification: bookmatched natural stone (typically Calacatta, Statuario, or Carrara marble), bespoke vanity units with brass or nickel detailing, freestanding cast-iron baths from Drummonds or The Water Monopoly, frameless walk-in showers, premium brassware (Lefroy Brooks, Samuel Heath, Watermark), and underfloor heating throughout. Cost is £25,000-£60,000 for a full master bathroom renovation. Build time 6-10 weeks. For listed properties, Listed Building Consent is required for any change to original features and we apply for it before work starts. Conservation-grade lime plaster is used on heritage walls.
Heritage painting and decorating
Kensington decoration involves heritage colours appropriate to the period of the property, specialist finishes including hand-applied distemper or limewash on original lime plaster, and proper restoration of original timber panelling, sash windows, and ornate plasterwork. We use Farrow & Ball, Little Greene, Edward Bulmer, or specialist heritage paint suppliers depending on the property. Cost for a full luxury townhouse repaint is £25,000-£60,000 depending on size, original feature complexity, and paint specification. Lead paint testing under HSE Control of Lead at Work guidance is essential on pre-1992 layers, particularly common on Kensington period properties.
Basement conversion under RBKC requirements
Kensington basement conversions face the most stringent policy requirements in London. RBKC requires Basement Impact Assessments covering hydrogeology, structural impact on neighbouring properties, and traffic management. Construction Traffic Management Plans are required for all but the smallest projects. Single-storey basements are typically permitted; multi-storey basements are restricted. Cost is £150,000-£500,000 for tanking and conversion to habitable use, depending on size and complexity. Build time 28-44 weeks. We work with specialist basement contractors and structural engineers experienced in RBKC requirements, and conservation consultants for listed buildings.

Frequently Asked Questions
- What's involved in working on a listed Kensington property?
- Substantial planning preparation. Many Kensington properties are Grade I or Grade II listed, requiring Listed Building Consent for virtually any change including internal layout alterations, removal or alteration of original features, replacement of original windows or doors, render colour, roof material, and even paint type changes. Application takes 12-16 weeks at the Royal Borough of Kensington and Chelsea. We work with conservation-specialist architects on listed projects and use heritage materials (lime mortar, slate, timber, conservation-grade glass) matched to the original. Listed Kensington work typically costs 40-70% more than equivalent work on a non-listed property and takes longer.
- Why are Kensington basement conversions so heavily regulated?
- Because of the cumulative impact of basement excavation in concentrated areas. RBKC introduced strict basement policy following neighbour complaints, structural concerns, and water table impacts in streets with multiple basement conversions. Requirements now include a Basement Impact Assessment (covering hydrogeology, structural impact, and ground conditions), a Construction Traffic Management Plan, and a Construction Management Plan covering hours of work, vehicle movements, dust, and noise. Single-storey basements are typically permitted; multi-storey basements are restricted in most streets. Application costs and timelines are significantly higher than for above-ground extensions.
- Why do Kensington renovations cost so much more than other London boroughs?
- Five reasons. First, listed building requirements add 40-70% to the cost of equivalent work. Second, RBKC's planning fees and application requirements are higher than most boroughs. Third, the local market expects luxury specification — natural stone, bespoke joinery, premium fixtures and finishes — which is significantly more expensive than mid-range trade specifications. Fourth, basement projects face strict regulatory requirements adding £20,000-£50,000 in assessment and management costs. Fifth, the trade rates in Kensington are at the top of the London market because of access constraints and high-end client expectations.
- Can I extend a Kensington townhouse?
- Yes, but with significant constraints. Almost the entire Royal Borough is covered by conservation areas, and many properties are listed. Front-facing changes are virtually never approved. Rear extensions on non-listed properties may be possible with appropriate design — typically traditional materials, sympathetic proportions, and limited size. Listed properties need Listed Building Consent for any extension and the application process is longer and more uncertain than for non-listed properties. RBKC's pre-application advice service is essential before committing to designs. We work with heritage consultants for all listed building extension work.
