What Order to Renovate a House in the UK: The Complete Sequence

The Correct Order of Works for a UK House Renovation

Embarking on a home renovation is an exciting venture, but without a clear roadmap, it can quickly become a logistical headache. So, what order to renovate a house in the UK? The standard sequence follows a logical progression:

Preparation & Demolition
Structural Work
First Fix (Electrical & Plumbing)
Plastering
Second Fix (Fittings)
Decoration & Flooring

Adhering to this order of work for home renovation prevents expensive rework. For instance, you wouldn't want to decorate before your professional plasterer in London has finished the walls, nor would you want to install electrical sockets before the plastering is complete.

This sequence is not arbitrary — it has been refined over decades of construction practice in the UK. Each stage creates the necessary conditions for the next. Structural work must be completed before services are run, because you cannot safely route electrical cables or plumbing pipes through walls that may still shift or be altered. First fix must be completed before plastering, because the plaster encases and protects those services. And plastering must be finished and fully dried before decoration, because any moisture left in the plaster will cause paint to bubble, flake, and fail within months.

In London specifically, where Victorian and Edwardian properties dominate large swathes of areas like Hackney, Islington, Lewisham, and Wandsworth, the complexity of renovation projects is often heightened. Older buildings may have lath and plaster walls, unexpected structural quirks, lead pipework, and outdated electrical wiring — all of which must be assessed and addressed in the correct sequence to avoid costly complications.

Stage 1: Preparation and Structural Work

The first phase of remodeling a house involves 'dirty' work: stripping out old carpets, removing unwanted walls, and tackling any structural modifications. If you are moving a chimney breast or installing steel beams, this must happen before any internal services are touched.

This stage can be broken down into several distinct steps:

1. Initial Survey and Planning Before a single item is removed, a thorough survey of the property should be carried out. This includes checking for asbestos (common in properties built before 2000, particularly in textured coatings, floor tiles, and pipe lagging), identifying load-bearing walls, and assessing the condition of the existing plaster and structure. In London, many properties fall under the jurisdiction of conservation areas or are listed buildings, which may restrict what structural changes you can make. Always check with your local council before beginning.

2. Obtaining Permissions For major structural work — removing chimney breasts, creating open-plan living spaces, or building extensions — you will likely need Building Regulations approval and possibly planning permission. This process can take anywhere from 4 to 8 weeks, so it should be initiated early in your project timeline.

3. Demolition and Strip-Out Once permissions are in place, strip-out begins. This includes removing old carpets and flooring, ripping out outdated kitchens and bathrooms, taking down partition walls, and stripping back damaged plaster from walls and ceilings. In older London properties, this stage frequently reveals surprises: original fireplaces hidden behind plasterboard, damp patches masked by thick paint, or ceiling timbers that need reinforcing.

4. Structural Modifications If you are knocking through walls to create open-plan spaces, installing RSJ steel beams to support upper floors, or underpinning foundations, this work must happen now. A structural engineer should be consulted and will issue calculations that your builder and Building Control officer will use. Steel beam installation typically costs between £1,500 and £4,000 depending on the span and complexity, and must be signed off before any walls are plastered over.

Practical Example: A homeowner in Clapham South, SW4, wanted to open up their Victorian ground floor by removing the wall between the front reception and rear dining room. Before any other work could proceed, a structural engineer was engaged (cost: approximately £600 for calculations), an RSJ beam was specified, temporary acrow props were installed, the wall was removed, and the beam was fitted and signed off by Building Control. Only then could the project move to the next stage. Attempting to run electrical cables or plaster walls before this structural work would have meant significant rework and potential safety issues.

Stage 2: First Fix (Electrical and Plumbing)

Once the structure is sound, your tradespeople will complete the 'first fix.' This includes running new electrical cables, installing plumbing pipework for radiators and bathrooms, and fitting back-boxes for sockets. This stage is essentially about putting the skeleton of your systems in place before they are hidden behind a fresh coat of plaster.

First fix is a critical stage that demands careful coordination between your electrician and plumber, as their work will often cross paths within walls, floors, and ceiling voids.

Electrical First Fix Your electrician will run new cable from the consumer unit (fuse board) to every socket, light fitting, and appliance position in the property. They will install metal or plastic back-boxes into the walls (chased into the masonry or clipped to studwork), which will be the housing for your sockets and switches once plastering is complete. In a typical three-bedroom London terraced house, a full rewire at first fix stage might take 3 to 5 days and cost between £2,000 and £4,500 for the first fix labour alone, with second fix and certification on top.

Plumbing First Fix Your plumber will install new pipework for central heating, bathrooms, and the kitchen. This includes running copper or plastic pipework through floors and walls, installing radiator valves, and fitting waste pipes for bathrooms and kitchens. Any underfloor heating systems — increasingly popular in London bathroom renovations — are also installed at this stage, before screed or tiles are laid.

Why First Fix Must Happen Before Plastering All of these cables, pipes, and back-boxes need to be concealed behind the finished plaster surface. If you plaster first, your tradespeople will have to chase out channels in your newly plastered walls to install their services — creating significant mess, additional cost, and an inferior finish. First fix typically takes 1 to 2 weeks for a full house, depending on the scope of the works.

Practical Example: A client in Finchley, N3, attempted to save money by having their plasterer start work before the electrician had finished first fix. The electrician then needed to chase five additional cable runs through freshly plastered walls, which cost an extra £400 in making-good work and resulted in visible patching on two walls that required re-skimming.

Stage 3: Plastering (The Critical Stage)

Plastering is the pivotal moment that transforms a construction site into a room. At London Plastering Service, we often see homeowners rush this stage, but it is the foundation of a high-quality finish.

Why Plastering Is the Most Important Stage

Plastering is the stage that defines the final appearance of every surface in your home. A poor plaster finish will show through even the most expensive paint, wallpaper, or decorative treatment. Conversely, a perfectly flat, seamless plaster finish makes every subsequent stage easier, quicker, and more professional in appearance.

There are several different types of plastering work that may be required during a renovation:

Re-skimming: Applying a thin finish coat of plaster (typically 2–3mm) over existing sound plasterwork. This is the most common requirement in London renovations, where walls may be damaged, marked, or textured from old wallpaper or Artex coatings. A standard bedroom re-skim costs approximately £200–£350 in London.

Dry Lining (Dot and Dab): Plasterboard is fixed directly to masonry walls using adhesive dabs, creating a flat, insulated surface that is then skimmed. This is particularly useful for dry lining and dot and dab new extensions or rooms with uneven brick walls.

Studwork and Boarding: New partition walls are built from metal or timber stud frames, covered in plasterboard, and then skimmed. This is how new rooms are created within a larger space.

Scratch Coat and Float: In properties being stripped back to brick, a two-coat system is applied — a scratch coat of sand and cement or bonding plaster, followed by a finish skim coat. This process takes longer but creates a durable, long-lasting surface.

Drying Time: The Critical Factor New plaster must be allowed to dry fully before any second-fix work, decoration, or flooring is undertaken. In normal UK conditions, a standard skim coat will take approximately 3 to 5 days to dry to a pale, uniform colour. However, in a fully replastered property or during winter months, full drying can take up to 4 to 6 weeks before the surface is stable enough for painting. Attempting to paint onto plaster that is not fully dry is one of the most common — and most costly — mistakes made during renovation projects.

During the drying period, adequate ventilation is essential. Open windows where possible, and avoid using portable gas heaters, which introduce moisture into the air and significantly slow the drying process. Electric fan heaters or dehumidifiers are the preferred method of accelerating drying in London properties, particularly during autumn and winter renovations.

Real-World Evidence: The Barnet Project

We recently completed a full house re-skim in Barnet, EN5. The client, David K., had stripped his bedroom ceilings back to the original battens. Our team spent three days re-skimming the entire property to create a perfectly flat, seamless finish.

"The finish on the ceiling is perfectly flat — you can't see a single join." — David K.

The Barnet project is a strong illustration of the sequence in practice. David had completed all structural work and first fix before we arrived. Our team boarded the ceilings where the old lath had been removed, applied bonding plaster to uneven areas, and then finish-skimmed every surface in the property over three days. The property was then left to dry for two weeks before David's decorator arrived to apply a mist coat followed by two coats of emulsion.

Whether you need dry lining and dot and dab for new partitions or a traditional re-skim, the plastering must be fully dry before moving to second-fix works. Check our skimming costs to budget effectively.

How to Prepare for the Plasterer's Arrival

To ensure the plastering stage goes smoothly and without delay, homeowners should ensure the following are in place before the plasterer arrives:

All first fix electrical and plumbing work is signed off and complete
All structural work is finished and approved by Building Control where required
The property is watertight — a roof that leaks during plastering can ruin an entire job
Access for materials is clear — plasterers work with heavy bags of plaster and large sheets of plasterboard (typically 2.4m x 1.2m), so clear access through doorways and stairwells is essential
Floors are protected with dust sheets, as plastering is a messy process
Water and electricity are available on site

Stage 4: Second Fix (Sockets, Switches, Fittings)

Once the plaster is dry, the electrician can fit the socket faces and light switches. Plumbers will connect radiators, taps, and sanitaryware. Because the walls are smooth and flat, these fittings will sit flush and professional.

Second fix is where the property starts to look and feel like a finished home. Your electrician will return to fit all of the socket face plates, switch plates, consumer unit covers, and light fittings. Your plumber will connect radiators, install bathroom suites, fit kitchen taps, and commission the boiler.

Why Second Fix Must Follow Plastering If fittings are installed before plastering, the plasterer must work around them — an almost impossible task that inevitably results in messy edges, gaps around socket plates, and an unprofessional finish. Worse, plaster splashed onto chrome taps, sanitaryware, or electrical components can cause permanent damage and void warranties.

In London projects, second fix typically takes 2 to 5 days for a full house, depending on the complexity of the electrical and plumbing installations. It is also the stage at which kitchen units are fitted — after plastering and before tiling, so that the tile line can be finished precisely to the top of the wall units.

Stage 5: Decoration and Finishing

Finally, with the heavy work done, you can paint, lay flooring, and install skirting boards. Painting onto a perfectly prepared, plastered surface is where the true aesthetic value of your renovation shows.

Decoration follows a specific internal sequence of its own:

Mist coat — new plaster is porous and must first receive a diluted mist coat (typically 3 parts emulsion to 1 part water) to seal the surface before full coats of paint are applied. Skipping the mist coat causes paint to be absorbed unevenly and peel.
Ceilings painted first — always paint ceilings before walls to avoid drips on freshly painted wall surfaces.
Walls painted — two full coats of emulsion are standard on new plaster.
Skirting boards and architraves fitted and painted — fitting skirting after plastering means a clean, flush junction between board and wall.
Flooring laid — hard flooring and carpets are always the last items to be installed, protecting them from all preceding works.
Final snagging — a walk-through to identify and rectify any minor imperfections before the property is occupied.

Practical Example: A homeowner in Tooting, SW17, who laid engineered oak flooring before plastering was complete found that plaster splashes had permanently stained the boards in three rooms, requiring partial replacement at a cost of approximately £900. Had the correct sequence been followed, this cost would have been entirely avoided.

How Long Does a Full House Renovation Take?

Depending on the scope, a full renovation can take anywhere from 3 to 9 months. Plastering, specifically, is a short-duration but high-impact task; our team can often complete a full house re-skim in 3–5 days, depending on the property size.

Here is a more detailed breakdown of realistic timeframes for a typical three-bedroom Victorian terraced house in London:

The drying time for plaster is often the most frustrating period for homeowners, as the property can appear ready but is not yet safe to proceed with decoration. During this period, use the time productively by ordering materials, confirming contractor schedules, and procuring fixtures and fittings.

Frequently Asked Questions

Q: Should I paint before or after plastering? A: Always after. Plaster must be fully dry and primed before painting to ensure the paint adheres correctly. New plaster that has not been allowed to dry fully and sealed with a mist coat will absorb paint unevenly, resulting in a patchy, dull finish that will require additional coats to correct.

Q: Does plastering mess up the floor? A: We use protective sheets, but it is best to have plastering done before installing expensive new flooring. Plaster splashes, while manageable on concrete subfloors, can permanently stain and damage timber, engineered wood, or luxury vinyl tile (LVT) flooring.

Q: How much should I budget for plastering? A: Prices vary by square meter. You can review our plastering prices in London for a transparent guide. As a rough benchmark, a full room re-skim (walls and ceiling) in a standard double bedroom in London typically costs between £350 and £600 depending on the condition of the existing surfaces and ease of access.

Q: Why is the 'order of work' so important? A: Skipping steps — like installing sockets before plastering — leads to ugly damage and costly repairs later. In our experience working across London, the cost of rework caused by incorrect sequencing is frequently higher than the original cost of doing the work correctly in the first place.

Q: What is the most common mistake? A: Rushing the drying time of new plaster, which can lead to cracking or damp issues when paint is applied too early. The second most common mistake is booking tradespeople in the wrong order, which leads to delays, abortive trips, and unnecessary costs.

Q: Can I live in my house during a full renovation? A: It is possible but can be extremely disruptive, particularly during plastering and first fix stages. Many homeowners choose to remain in the property during the decoration phase, which is considerably less intrusive. During the plastering stage specifically, dust and damp conditions make habitation uncomfortable and can interfere with the drying process.

Q: Do I need to inform my neighbours before starting a major renovation in London? A: For most internal renovations, you are not legally required to notify neighbours, though it is courteous to do so and give them advance warning of likely noisy periods. If your project involves work on a shared (party) wall — which is extremely common in London terraced and semi-detached properties — you will be legally required to serve a Party Wall Notice under the Party Wall etc. Act 1996, typically at least two months before work begins.

Q: What type of plaster is best for London's older properties? A: Many Victorian and Edwardian properties in London have walls that flex and move slightly with seasonal changes in temperature and humidity. For these properties, a finish coat of Thistle Multi-Finish or Thistle Hardwall bonding followed by a finish skim is typically recommended. Lime plaster is also increasingly popular for period properties as it is more breathable and flexible than modern gypsum plasters, making it particularly well-suited to solid brick walls that need to manage moisture vapour.

Q: How do I find a reliable plasterer in London? A: Look for a plasterer who can provide references from recent similar projects, photographs of completed work, and clear written quotes that detail exactly what is included. At London Plastering Service, we provide transparent, itemised quotes with no hidden costs and are happy to share our portfolio of completed projects across London.
