Getting started on a renovation or extension

Home Renovation & Extension Checklist

The early months of the new year are a great time to start thinking about your renovation or extension plans. It's a complicated process, you can easily get decision-making overload, and the process can get a bit muddy. So, here's a step-by-step checklist to guide you through the process:


1. Define Your Vision

✅ Decide what you want to achieve (e.g., more space, better layout, modern updates).

✅ Create a wish list of must-haves and nice-to-haves.

✅ Research inspiration (Pinterest, Instagram, magazines) to gather ideas.

✅ Consider how the renovation will complement your home’s existing character and period features.


2. Set Your Budget

✅ Determine your budget, including a contingency fund (10-20% extra for unexpected costs).

✅ Research average costs for similar projects in your area.

✅ Get quotes from contractors or professionals for early estimates.


3. Check Planning Requirements

✅ Research whether your project requires planning permission (use the council's planning portal).

✅ Consider permitted development rights for smaller projects.

✅ Check for restrictions if your property is listed or in a conservation area.


4. Assemble Your Team

✅ Hire an architect or designer to create detailed plans (especially for extensions).

✅ Consult with a structural engineer if needed.

✅ Find reputable builders and tradespeople (ask for references and see their work).

✅ Consider hiring an interior designer to refine your plans, ensure the interiors work with how your want to live and add finishing touches.


5. Research and Prepare

✅ Investigate any party wall agreements or neighbour considerations.

✅ Check for building regulations and ensure compliance.

✅ Arrange for a surveyor if your home is older or requires structural assessments.

✅ Think about sustainability – can you incorporate energy-efficient solutions or reclaimed materials?


6. Finalise Plans

✅ Work with your architect/designer to finalise layouts and designs.

✅ Decide on materials, fixtures and finishes (from flooring to light fittings).

✅ Obtain multiple quotes to compare prices and timelines.


7. Plan for the Disruption

✅ Decide whether you’ll live on-site or move out during the work.

✅ Inform neighbours of the project and anticipated timelines.

✅ Organise storage for furniture or belongings that may need to be moved.


8. Permissions and Insurance

✅ Apply for planning permission (if needed) and wait for approval.

✅ Notify your insurer about the project and update your home insurance policy.

✅ Arrange for a building control officer to inspect and sign off on key stages.


9. Start the Project

✅ Confirm timelines and schedules with your builder.

✅ Regularly communicate with your team to stay on top of progress.

✅ Keep detailed records of costs, receipts and contracts.


10. Post-Completion Tasks

✅ Obtain completion certificates for building regulations compliance.

✅ Update your insurance to reflect the changes.

✅ Add the finishing touches – think about decorating, furnishing and styling your new space.



Tip: For period properties, consult specialists to preserve original features and maintain historical integrity. You may need Listed Building Consent as well as planning permission. Even if your property isn't listed, it's best to talk to the experts first, before work clears away important historical details.
