A full house refurbishment is one of the most complex residential projects a homeowner can undertake. It's not just a big decorating job. Done properly, it touches structure, services, fabric, and finishes — and the order in which you do things determines whether the project runs cleanly or becomes an expensive series of do-overs. This guide covers how to scope a refurbishment, why sequencing matters, and what to look for in a contractor.
What "Full Refurbishment" Actually Means
The term gets used loosely. For this guide, a full house refurbishment means a project that involves most or all of the following:
- Structural alterations (removing walls, modifying openings, inserting steels)
- Full re-wire of electrical installation
- Full replumbing or significant plumbing alterations
- New central heating system or heat pump installation
- Kitchen and bathroom strip-out and refit
- Internal wall reconfiguration
- New flooring throughout
- Full decoration
Partial refurbishments — where you're doing a kitchen and two bathrooms but leaving the electrics — are simpler to manage. A true full refurbishment in London typically runs £60,000–£200,000+ depending on property size and specification.
How to Scope It Properly
The single biggest mistake homeowners make at this stage is starting with mood boards before understanding the building. Before you decide on kitchen layouts or tile specifications, you need to know:
1. What the building contains. An older London terraced house often has original wiring (rubber-insulated cables), lead water pipes, solid masonry party walls with no insulation, and suspended timber floors with minimal under-floor depth. These aren't cosmetic issues — they affect cost and programme significantly.
2. Which walls are structural. You cannot assume any wall is non-structural without a proper assessment. In Victorian and Edwardian terraces, internal walls are frequently load-bearing. You need a structural engineer to confirm this before you design around open-plan layouts.
3. What planning restrictions apply. Full internal refurbishments rarely need planning permission. But if you're altering the exterior (new windows, doors, rooflights) or if the property is listed or in a conservation area, permitted development rights may be restricted.
Once you understand the building, you can scope the work — and only then does it make sense to get into design and specification.
Why Sequencing Is the Most Underrated Part of a Refurbishment
The order in which trades work through a property is not optional. Get it wrong and you'll be chasing your tail — replastering walls you've already tiled, rerouting pipes under floors you've already laid, rewiring through ceilings you've already plastered.
The correct sequence for a full house refurbishment is broadly:
- Strip-out — remove all fixtures, fittings, floor coverings, and any partitions to be demolished
- Structural work — install steels, modify openings, build new partitions
- First fix M&E — mechanical and electrical first fix: cable runs, pipework, ductwork, underfloor heating loops. This happens before plastering, because it all goes in the walls and floors
- Insulation — floor, wall, and ceiling insulation as required
- Plasterwork — walls and ceilings
- Second fix M&E — sockets, switches, sanitaryware, radiators, boiler commissioning
- Joinery — doors, skirtings, architraves, staircases
- Kitchen and bathroom fit-out
- Flooring
- Decoration
This is the order for a reason. Mechanical and electrical (M&E) first fix must happen before plaster. Flooring goes in after the bathroom fit-out because tilers will damage a finished floor. Decoration is last, full stop.
A contractor who doesn't sequence the work this way — or who lets trades overlap without proper coordination — will cost you time and money putting things right.
The Most Common Mistakes in Full House Refurbishments
Starting without a full scope. Deciding to "see what we find" and add work as you go sounds flexible. In practice, it means no fixed price, no programme, and a project that runs on indefinitely.
Appointing separate trades without a coordinator. Some homeowners appoint an electrician, a plumber, a plasterer, and a carpenter separately. The problem is coordination: when the electrician finishes first fix on Thursday, who tells the plumber the floor is ready? Who manages the overlap? Who is responsible when the plumber's pipe run conflicts with the electrician's cable route? Without a single point of coordination, this becomes your problem.
Underestimating the M&E budget. A full rewire of a 3-bedroom London terraced house runs £6,000–£12,000. Full replumbing runs £8,000–£15,000. A new boiler and heating system adds £3,000–£8,000. These are not optional — they're the foundation of a safe, functional home.
Ignoring Building Control. Electrical work, structural alterations, plumbing changes, and energy efficiency upgrades all have Building Regulations implications. A reputable contractor will handle Building Control notifications and inspections as part of the project. If a contractor tells you it's not needed, that's a red flag.
Why a Principal Contractor Approach Works Better
A principal contractor takes legal and practical responsibility for the entire project. They manage all subcontractors, hold the site, handle Health & Safety compliance, and provide a single contract and single point of accountability. You don't manage trades — they do.
The alternative — acting as your own project manager across multiple separate contracts — is theoretically cheaper but practically much higher risk. Most homeowners who've tried it and regret it say the same thing: the time, stress, and rework cost more than the contractor margin they saved.
