Planning Your Spring 2026 Home Project - When to Start

As 2025 draws to a close, homeowners across the South of England are already looking ahead to their next big project. Spring is traditionally the most popular season to start building work, and with the weather improving and daylight hours increasing, it is easy to see why.

If you are planning a home extension, a renovation, or even a complete rebuild in 2026, the key to success is timing. The most common mistake homeowners make is waiting too long to begin preparations. Here is how to stay ahead and make sure your spring project runs smoothly.

Start planning before the end of the year

Autumn and early winter are the perfect months to begin conversations with your architect or builder. Design drawings, initial quotes, and early planning discussions often take six to eight weeks. If your project needs planning permission, allow another two to three months for the local authority to process it.

Starting the design process in October or November 2025 puts you on track to begin building work in March or April 2026. Councils across the South Coast are always busier after Christmas, so the earlier you apply, the better.

Secure your builder in advance

Good builders and tradespeople are already scheduling projects for next spring. Across Dorset, Hampshire, and the wider South of England, lead times of three to six months are common. Booking early helps you secure both the date and a firm price before workloads increase. It also gives you time to finalise finishes and materials at your own pace.

Order materials early

While supply chains have stabilised since 2023, certain products still take time to arrive. Custom windows, doors, and kitchens can have lead times of two to three months, especially if they are bespoke. Ordering early avoids delays once work begins.

Many southern builders are still seeing occasional shortages in insulation, roof tiles, and glazing, so it is worth discussing orders with your contractor in advance.

Prepare your site and paperwork

Before construction begins, make sure planning approval and building regulations are fully cleared. If your project involves shared boundaries, arrange any party wall agreements early.

It is also a good time to check access for skips, scaffolding, and deliveries. Narrow driveways or coastal roads can be tricky, so sorting this now saves time later.

Review your budget carefully

Material prices have settled, but most experts expect them to remain steady through 2026 rather than fall. Allow a ten to fifteen percent contingency in your budget for unexpected issues such as hidden structural repairs or design changes.

Builders across the South of England recommend finalising finance and quotes before Christmas to lock in pricing and avoid spring increases.

The takeaway

If you are hoping to start work next spring, the time to act is now. By planning early, booking your builder, and finalising designs before the festive period, you will be ready to begin as soon as the weather improves.

Early preparation means more choice, better scheduling, and fewer surprises once construction begins. For homeowners across Dorset and the wider South of England, starting the process this autumn is the smartest move for a successful spring project.
