Renovation order matters because the wrong sequence creates rework, delays, and budget creep. In West London, this is amplified by period properties, shared walls, restricted access, and planning or conservation constraints. A controlled renovation sequence helps you protect building fabric, avoid finishing a room twice, and keep trades moving logically from structural work through to final detailing. This guide sets out a step-by-step renovation order that works for most homes, with specific notes for Chelsea, Fulham, Kensington and Notting Hill.

Quick Answer

Start with surveys, investigation and a clear scope
Secure planning, party wall matters and a building control approach early
Strip out and complete structural and damp remediation first
Make the building watertight before internal finishes
First fix services next, then plastering and second fix
Fit kitchens and bathrooms after second fix, then decorate and lay final flooring
Finish with snagging, commissioning and handover

Why Renovation Order Matters (And What Goes Wrong When You Get It Backwards)

The cost of rework in London projects

The biggest cost of poor sequencing is duplicated labour. If you decorate before addressing damp, you pay twice. If you fit joinery before first fix electrics, trades damage finished work and you end up patching and repainting. If you install flooring before heavy work is complete, it gets scratched, stained, or lifted to run services. In London, where labour and logistics are expensive, these mistakes quickly consume contingency.

Common triggers for delay

Renovations usually slow down for predictable reasons: long lead times for kitchens and bathrooms, access constraints for deliveries and waste removal, permissions and party wall processes, and late design decisions. The more you can lock down scope and sequencing early, the less your programme is exposed to avoidable delays.

Step 1: Pre-Works Planning and Investigation

Survey, measured drawings and condition checks

Start with the facts. Commission a building survey if you have not already, and obtain measured drawings if layouts are changing. If you plan structural alterations, involve a structural engineer early so steels and load paths are designed before demolition. If drainage condition is unknown, a drainage survey can prevent unpleasant surprises once floors and gardens are opened.

Scope, budget and specification level

Define what is included and excluded. Agree your scope, your target finish level, and any allowances for kitchens, bathrooms, ironmongery, lighting and joinery. Set a contingency that reflects risk, especially in period homes where opening up often reveals hidden work. A clear scope is the foundation of a reliable quote and a controlled programme.

Permissions and notices

Confirm whether you need planning approval, listed building consent, or conservation area considerations. If the property is attached, start the party wall process early to avoid programme delays. Decide how building control will be handled and what inspections are required. In West London, the administrative side can be as time-critical as the build itself.

Step 2: Strip Out and Enabling Works

Strip out safely and systematically

Isolate services, protect any elements being retained, and plan waste removal and logistics. A controlled strip out sets the site up properly for the trades that follow. In tight West London streets, think about skip permits, parking suspensions and how materials will be brought in and out without disrupting neighbours.

Expose unknowns early

Opening up early reduces risk later. Lift selected floors, open service routes, and inspect areas where damp or movement is suspected. This is when you find tired joists, bridged damp proof courses, hidden leaks, or unsafe wiring. It is far better to discover and price these issues now than after finishes are installed.

Step 3: Building Health First (Damp, Timber, Structural Corrections)

Damp diagnosis and remediation

Before you close up walls or apply new finishes, resolve moisture sources. Distinguish rising damp from condensation and penetrating damp, and specify the right remedy. In solid wall properties, material compatibility matters, including plaster build-ups and breathability. If you need damp investigation or remedial work, see our Damp Proofing page.

Timber and subfloor repairs

Address joists, floor strengthening, subfloor ventilation and timber decay before first fix. Period properties often have areas of localised rot or inadequate airflow. Fixing this now prevents future movement, squeaks, and ongoing moisture problems that can undermine finishes.

Structural works and layout changes

Complete structural alterations before services and finishes. This includes removing or altering load-bearing walls, inserting steels, chimney breast work, and floor strengthening. Structural work affects everything that follows, so it needs to be correct and signed off.

Step 4: Make the Building Watertight (External Envelope)

Roofing, gutters, drainage and external repairs

Stop water ingress before internal finishes. Roofing defects, failed gutters, poor drainage falls and external cracks can introduce moisture that ruins plaster and decoration. External repairs are often less visible than interiors, but they protect the entire investment.

Windows and doors where relevant

If windows and doors are being replaced, schedule them to align with security and weather performance. In many projects, it is best to have the building secure and weather-tight before the most sensitive internal trades begin. Confirm lead times early because joinery and glazing can be programme-critical.

Step 5: First Fix Services

Electrical, plumbing and heating

First fix is where the hidden infrastructure goes in. Route electrics, plumbing and heating pipework to the correct locations before walls are closed and floors are finished. Confirm zoning, consumer unit requirements, hot water capacity and whether you are retaining a boiler, moving to a heat pump, or adding underfloor heating. Changes later are expensive, so get the layout and specification right now.

Ventilation strategy

Ventilation is a performance issue, not an afterthought. Bathrooms and kitchens need correct extraction, and lower ground spaces often need an explicit strategy to manage humidity. In period homes, good ventilation helps protect timber and plaster. Poor ventilation leads to condensation, mould risk, and premature failure of finishes.

Smart wiring and future-proofing

If you want data points, speaker cabling, security wiring, or network infrastructure, run it now while walls are open. Even if you are not installing the full system immediately, future-proofing at first fix is far cheaper than retrofitting later.

Step 6: Plastering, Insulation and Internal Preparation

Plastering and wall build-ups

Once first fix is complete, close up walls and proceed with plastering. In solid wall properties, specify build-ups that avoid trapping moisture and remain compatible with the building fabric. Rushing plastering or using incorrect materials can cause cracking, debonding and long-term moisture problems.

Floors and screeds

Prepare floors for final finishes. This may include levelling, screeds, substrate repairs and underfloor heating build-up where applicable. Floor preparation impacts the quality of the final result more than many people expect. A perfect floor finish is only possible on a properly prepared substrate.

Step 7: Second Fix Services and Joinery

Second fix electrics and plumbing

Second fix includes sockets, switches, lighting plates, radiators, sanitary connections and final plumbing hook-ups. At this stage, accuracy and care matter because the visible details define the finished look.

Joinery and carpentry

Fit doors, skirting, architraves, built-in storage and carpentry details after plastering is complete and the building is stable. Joinery should be protected during remaining works, but installed early enough that decoration can properly finish it.

Step 8: Kitchen, Bathrooms and Final Finishes

Kitchen installation sequencing

Install cabinetry, then template and fit worktops, then integrate appliances and complete final connections. Kitchen lead times can drive the entire programme, so order early and confirm dimensions after structural and plastering work is complete.

Bathrooms and waterproofing

Bathrooms require careful sequencing. Waterproofing, correct tanking where required, tiling, ventilation and final snagging all need time and precision. Waterproofing and detailing should never be rushed to meet a deadline.

Decoration and final flooring

Decorate before final flooring where possible, then lay final floor finishes to reduce damage. If carpets are being installed, keep them until the very end. The goal is to protect finished work and reduce snagging caused by later trades.

Step 9: Snagging, Commissioning and Handover

Testing and certification

Commission systems and obtain certification. This typically includes electrical certification, gas safety where relevant, and verification of ventilation performance. If you have underfloor heating, smart controls or mechanical ventilation, make sure everything is tested and explained.

Final snag list and care guidance

Complete a structured snag list and resolve issues before sign-off. A good handover includes maintenance guidance, care instructions for finishes, and a clear understanding of what to monitor over the first few months as the building settles.

Access and logistics planning

Plan deliveries, waste removal, working hours and parking suspensions early. Narrow streets, restricted access and neighbour proximity can add time and cost. A well-run logistics plan reduces friction, keeps the programme moving and protects relationships with neighbours.

Party walls and shared structures

In terraced and semi-detached properties, party wall matters can drive timing. Build buffers into the programme, and avoid starting structural work before notices and agreements are in place. Shared structures also influence sequencing because noise, vibration and access need careful management.

Period property risks

Period homes often bring damp risk, timber issues, uneven floors and heritage detailing that must be reinstated properly. Breathability and material compatibility are essential, especially when upgrading insulation or plaster systems. If your project is a period home, see more information on the Period Property Renovation page.

FAQs

In what order do you renovate a house?

A typical renovation order is planning and investigation, permissions, strip out, building health and structural works, external weatherproofing, first fix services, plastering and preparation, second fix services and joinery, kitchens and bathrooms, decoration and final flooring, then snagging and handover. This sequence reduces rework and protects finished surfaces.

In what order should a house be remodelled?

Remodelling follows the same principles as renovation, but structural changes and services routing are usually more significant. Define the layout and engineering first, complete demolition and structural works early, then run services, close up and plaster, and only then move into kitchens, bathrooms and finishes. The main rule is to complete disruptive work before sensitive finishes begin.

What comes first in a house renovation?

Investigation and scope come first. Confirm the condition of the building, agree the scope and specification level, then address permissions and party wall matters. If you skip this stage, the project often becomes reactive, which leads to budget drift and delays.

What are the most common renovation mistakes?

Common mistakes include decorating before resolving damp, ordering kitchens before dimensions are final, moving services without a plan, underestimating lead times, and failing to allow contingency in period properties. Another frequent error is poor sequencing, which causes trades to redo work and damages completed finishes.

When should you fit the kitchen in a renovation order?

Fit the kitchen after plastering and second fix infrastructure is ready, but before final decoration is fully completed, so finishing and detailing can be completed cleanly. Cabinetry typically goes in before worktops and appliances, with final connections completed at the end of installation.

How do you sequence renovations in a Victorian or Edwardian home?

Start with building health. Investigate damp, timber condition and structure early, then complete remedial works before closing up walls or applying new finishes. Use compatible materials for solid walls and ensure ventilation is planned. Heritage details should be protected during strip out and reinstated after structural and plastering work is complete.
