How to Plan a Flat Refurbishment in London

How to Plan a Flat Refurbishment in London

Introduction

Flat refurbishments in London are a distinct category of project. Unlike a house renovation, a flat refurbishment involves shared building elements, lease obligations, management company involvement, and planning rules that specifically affect flats differently from houses.

Getting the approach right from the beginning makes the difference between a smooth project and one that stalls over permissions, neighbour complaints, or lease complications. This guide sets out the key steps involved in planning a flat refurbishment in London.

Step 1: Review Your Lease

Your lease is the starting point for any significant works to a leasehold flat. Most residential flat leases in London require you to obtain the freeholder's or managing agent's consent before carrying out alterations — which typically covers anything beyond simple redecoration.

Common lease restrictions include: - No removal of internal walls without consent - No changes to the electrical or plumbing systems without consent - No changes to flooring from carpet to hard floor (particularly in upper-floor flats, due to noise impact below) - No alterations to the external fabric of the building

Carrying out works without the required consent can result in breach of lease proceedings, which may need to be resolved before you can sell the property.

Before you instruct an architect or contractor, read your lease and identify whether consent is required. Your solicitor can help if the lease is complex.

Step 2: Notify the Managing Agent

Even where the lease doesn't require a formal licence to alter, the managing agent or management company should be informed of any works affecting the building's common areas, structural elements, or M&E systems. This includes works to:

  • Party walls (shared with neighbouring flats)
  • The building's drainage system
  • Electrical supplies shared with the building
  • Communal areas that may be affected by the works

In practice, this means notifying the managing agent before works begin and confirming in writing when the project is complete.

Step 3: Understand Planning Restrictions for Flats

Flats do not have the same permitted development rights as houses. Almost all external alterations to a flat require a planning application. This includes:

  • Adding roof lights or Velux windows
  • Changing windows or doors on the front elevation
  • Any external extension or addition

For internal works only — a kitchen refurbishment, bathroom replacement, or replastering — planning permission is not required.

Step 4: Building Regulations

Building Regulations apply to certain types of works inside a flat, including:

  • Electrical installation work (new circuits, consumer unit replacements)
  • Plumbing work involving new appliances
  • Wall removal (if the wall is load-bearing or a compartment wall between flats)
  • New boiler installation

For electrical work in domestic settings, the contractor must be registered with a competent person scheme (such as NICEIC or NAPIT) and self-certify the work, or a Building Notice must be submitted to the local authority.

For structural alterations in a flat — even internal ones — a structural engineer may be needed to assess the wall before any removal proceeds.

Step 5: Consider the Neighbours

A flat refurbishment almost inevitably creates noise, vibration, dust, and access issues that affect neighbours above, below, and beside you. Professional management of this includes:

  • Communicating with neighbours before work begins — a courtesy letter explaining the scope and anticipated duration
  • Restricting noisy work to permitted hours (typically 8am–6pm Monday–Friday, 8am–1pm Saturdays, not at all on Sundays)
  • Managing dust carefully in shared entrance halls and stairwells
  • Ensuring delivery of materials doesn't block access

Neighbours who are kept informed and treated respectfully are far less likely to cause delays through complaints or building management involvement.

Step 6: Sequence the Works Properly

A flat refurbishment should follow a logical sequence. Typically:

  1. Strip out and demolition (if applicable)
  2. Structural works (if required)
  3. First-fix electrical and plumbing
  4. Plastering
  5. Second-fix electrical and plumbing
  6. Tiling (kitchens and bathrooms)
  7. Joinery (skirting, architraves, fitted furniture)
  8. Decoration
  9. Flooring
  10. Fitting kitchen and bathroom units and appliances

Attempting to skip stages or run incompatible works simultaneously creates problems that are more expensive to fix than they would have been to avoid.
