A whole-house renovation is one of the biggest investments most homeowners will make, and it’s also one of the least predictable — timelines shift, trades overlap, and the process can feel opaque if you don’t know what’s coming next. At Alborz Groups, we believe clarity is the first thing a good renovation partner should offer. Here’s a realistic, month-by-month look at how a full home renovation typically unfolds in the UK, from first conversation to final handover.
Month 1: Consultation, Design and Planning
Every renovation starts before a single wall comes down. The first month is about establishing the brief: how you use your home, what isn’t working, and what success looks like once the project is finished. This is where an architect or designer will survey the property, discuss structural possibilities, and begin developing concept designs.
For most whole-house projects, this stage also includes early conversations about planning permission and Building Regulations. Not every renovation needs planning consent — many internal works and even some extensions fall under Permitted Development — but it’s essential to establish this early, since it directly affects your timeline. By the end of month one, you should have a clear design direction and a realistic sense of what regulatory approvals, if any, are required.
Month 2: Detailed Design and Approvals
With the concept agreed, month two is about turning ideas into buildable drawings. This includes detailed architectural plans, structural engineering input where load-bearing walls or extensions are involved, and specifications for materials and finishes.
If planning permission is needed, this is typically when the application is submitted — and it’s worth knowing that standard planning decisions in England can take around eight weeks, sometimes longer if the local authority requests amendments. Building Regulations approval runs in parallel and covers technical compliance: insulation, fire safety, ventilation, and structural integrity. A good contractor will use this waiting period productively — finalising material orders, confirming trade availability, and preparing a detailed programme of works so there’s no dead time once approvals land.
Month 3: Tendering, Contracts and Pre-Start
Once designs and approvals are in place, month three is typically spent finalising the build team. This means tendering the project to contractors (or confirming scope with your chosen one), agreeing a fixed price or schedule of works, and signing contracts that clearly define scope, payment stages, and timelines.
This is also when practical groundwork happens: skip permits, scaffolding licences, party wall agreements with neighbours if relevant, and utility disconnections are arranged. Homeowners often underestimate this administrative stage, but skipping it causes far more delay later than doing it properly now. By the end of month three, you should have a signed contract, a confirmed start date, and a site ready for work to begin.
Month 4: Strip-Out and Structural Work
This is where the renovation becomes visible. Month four typically begins with a full strip-out — removing old kitchens, bathrooms, flooring, and any fixtures being replaced — followed by structural work. This can include removing internal walls, installing steel beams, forming new openings, or beginning any extension groundworks.
It’s the loudest, dustiest, and most disruptive phase of the project, and it’s also when hidden issues are most likely to surface: damp, outdated wiring, or structural quirks that weren’t visible until the walls came down. A well-managed project builds in contingency time and budget for exactly this reason.
Month 5: First Fix
With the structural shell established, month five moves into “first fix” — the unseen infrastructure that everything else depends on. This includes new electrical wiring, plumbing pipework, heating systems, and any structural carpentry like stud walls or floor joists. Insulation is also typically installed at this stage.
First fix is unglamorous but critical. Mistakes here are expensive to correct later, so this is the point where a detailed specification and clear communication between architect, contractor, and trades really pays off.
Month 6: Plastering and Internal Finishes Begin
Once first fix is signed off, plastering transforms bare stud walls and exposed brick into finished rooms. This is often the month homeowners feel real progress for the first time — the shape of the house becomes tangible again. Flooring substrates are prepared, and depending on the project, joinery such as staircases or built-in storage may begin.
Month 7: Second Fix
Second fix is where the house starts to function again. Kitchens and bathrooms are fitted, electrical sockets and switches installed, radiators connected, doors hung, and skirting boards fixed. This month tends to involve the highest number of trades on site simultaneously — electricians, plumbers, joiners, and tilers often overlapping — so good site management is essential to avoid one trade holding up another.
Month 8: Decoration and Snagging
With all major systems in place, month eight moves into decoration: painting, final flooring, and finishing details. Toward the end of this month, a snagging process should begin — a systematic walkthrough to identify anything that needs adjustment, from a sticking door to a paint touch-up. A thorough snagging list, addressed before handover, prevents small issues from becoming ongoing frustrations.
Month 9: Final Handover
The final month is about completion and certification. This includes Building Regulations sign-off, electrical and gas safety certificates, a deep clean, and a final walkthrough with the client. Any remaining snagging items are resolved, and you receive your completed home along with warranties and certification documents for future reference.
A Note on Timelines
Nine months is a realistic range for a substantial whole-house renovation, but every project is different. Smaller renovations may complete in four to six months, while projects involving significant extensions, listed building consent, or complex planning negotiations can run longer. The single biggest factor in staying on schedule isn’t the build itself — it’s the quality of planning and design work done before anyone picks up a tool.
If you’re considering a whole-house renovation and want a clear, realistic timeline for your specific project, Alborz Groups would be glad to talk through your plans and what’s involved from day one.
