Introduction

Most homeowners want to know two things at the beginning of a renovation: how much will it cost, and how long will it take?

The second question can be just as difficult to answer as the first.

A renovation is rarely one continuous period of building work. Time is also needed for design, approvals, technical details, quotations and preparation.

The planning stage often takes longer than expected

A straightforward project may move quickly, while a larger renovation can spend several months in design and preparation.

That time is not wasted. It is when layouts are tested, decisions are made and the information needed for accurate quotations is prepared.

Rushing this stage can simply move the delays into the build itself.

Approvals can affect the programme

If planning permission is required, allow time for the application and any conditions attached to an approval.

Projects involving party wall notices, specialist surveys or listed buildings may need additional time before construction begins.

How long might the building work take?

A focused kitchen or bathroom renovation may take a matter of weeks.

An extension often takes several months, while a whole-house renovation can take six months or longer depending on the scope.

The team, materials, structural complexity and changes during the build can all affect the finish date.

How can you keep things moving?

Make key decisions before they become urgent.

Confirm long-lead items early, respond promptly when information is needed and try to avoid major design changes once work is underway.

Final thoughts

A renovation timeline begins long before the first day on site.

Think in stages: design, approvals, technical preparation, contractor selection and construction.

Taking enough time at the beginning often leads to a smoother build later.
