Bathroom renovation in NW3
What the project covers
Properties in the NW3 postcode — Prestigious North West London postcode. Large Victorian and Edwardian detached houses. High-end maintenance and compliance market. Our team has worked across this postcode and understands the typical drainage configurations, joist layouts and building management requirements.
A full renovation covers the complete sequence: strip out of the existing suite and tiles, first fix replumbing of supply and waste connections, tiling with proper waterproofing in all wet zones, suite installation and final second fix plumbing, electrical works within bathroom zones, and finishing with silicone seals and accessories.
All electrical works within bathroom zones — including extractor fans, heated towel rails, shaver sockets and heated mirrors — are carried out by our Part P registered electricians. Every installation is certificated and notified to the local authority. You receive the electrical installation certificate as part of the project handover pack.
Wet rooms in upper-floor flats require particular care. Full waterproof tanking of all walls and the floor must be completed and allowed to cure before tiling begins. Drain position relative to the floor joists is determined at the design stage, not after the floor has been opened. We carry out this survey as part of the pre-works consultation to avoid programme delays during the project.
For leasehold properties in NW3, notification to the building management company is required before any works that affect shared drainage stacks or building structure. We provide guidance on this as part of the pre-works process and can supply the required method statements for managing agents if needed.

Common questions
Bathroom renovation NW3: frequently asked
How long does a bathroom renovation take in London?
A standard bathroom renovation in London typically takes 1 to 2 weeks from strip out to final finish. Wet rooms may take slightly longer due to the required drying time for the waterproof membrane before tiling can begin. For tenanted properties, factor in that the property will be without a bathroom during this period — we recommend coordinating the work between tenancies where possible.
How much does a bathroom renovation cost in London?
Bathroom renovation costs in London vary by scope and finish. A basic refresh with a new suite and tiling typically costs between 3,000 and 5,000 pounds. A mid-range full renovation including replumbing, tiling and electrical works runs from 5,000 to 8,000 pounds. A premium wet room or luxury finish with underfloor heating and high-end materials can reach 8,000 to 15,000 pounds or more. We provide a fixed quote after a site visit.
Do I need planning permission to renovate my bathroom in London?
Planning permission is generally not required for an internal bathroom renovation. However, listed buildings and properties in conservation areas — both common across London — may require consent for any new external vent openings. If your property is a leasehold flat, you should notify your building management company before works begin. Our team can advise on any consents relevant to your specific property.
Can you renovate a bathroom in a tenanted property?
Yes. We regularly carry out bathroom renovations in tenanted London properties. Coordination with tenants is essential — the property will be without a working bathroom during the works. We provide clear daily progress updates and aim to minimise disruption. For landlords, we can also issue all relevant certificates including Part P notification on completion.
