How Long Will My Refurbishment Take? A Realistic Timeline for London Homes

One of the most common questions we hear from clients is how long will my refurbishment take. It is a question that deserves an honest and detailed answer, because unrealistic expectations around timing are one of the biggest sources of frustration in any building project. Here is what you can realistically expect for a refurbishment in prime London.

The Pre Construction Phase

Before any building work begins, there is a significant amount of preparation required. Design development, planning applications, building control submissions, party wall agreements, freeholder licences, and procurement all take time. For a comprehensive refurbishment, this pre construction phase typically takes three to six months. Rushing this stage almost always leads to problems later. At NU Projects, we invest heavily in pre construction planning because it is the single most effective way to keep a project on track once work begins.

Typical Construction Timelines

The duration of the construction phase depends on the size and complexity of the project. As a general guide, a full refurbishment of a two bedroom apartment in prime London typically takes four to six months. A large townhouse refurbishment with structural alterations might take eight to twelve months. A project involving a basement extension can add six to twelve months to the overall programme. These are realistic timescales for high quality work. Any contractor who promises significantly shorter programmes for complex projects should be questioned carefully.

What Can Cause Delays

Delays in construction are common, but most are avoidable with proper planning. The most frequent causes include late design decisions, changes to the scope of work during construction, slow approval processes from freeholders or local authorities, supply chain issues with specialist materials, and unforeseen structural or building fabric problems revealed during demolition. Weather can also affect programmes, particularly for projects involving external works or roof alterations. At NU Projects, we build realistic float into our programmes and communicate proactively when any issue arises that could affect the timeline.

How We Keep Projects on Track

Effective programme management requires discipline, communication, and experience. We produce detailed construction programmes at the start of every project and update them regularly. Our clients receive weekly progress reports with clear commentary on what has been completed, what is coming next, and whether the programme is on track. We hold regular site meetings with the design team to review progress and resolve any issues quickly. This structured approach is how we consistently deliver projects within the agreed timeframe.

The Importance of Choosing the Right Sequence

The order in which work is carried out has a significant impact on the overall programme. Efficient sequencing means that different trades can work in parallel without getting in each other's way. Poor sequencing leads to trades standing idle, waiting for access, and the programme extending unnecessarily. An experienced contractor understands how to sequence a project for maximum efficiency while maintaining the highest standards of quality and safety.
