I want to prevent a future flood.

How the Grant Process Actually Works

The City of London covers up to 90% of eligible costs to protect your home, but the approval process is strict. You cannot simply hire a contractor and send the City the bill.

To successfully receive funding, you must follow a specific sequence of estimates, approvals, and inspections. Breaking ground before you have written City approval will instantly void your eligibility. Here is a high-level snapshot of the official path:

Frequently Asked Questions

Can I start the work now and get reimbursed later? ▼
No. The program is not retroactive, meaning any work started before you receive written approval from the City is ineligible for funding. You must wait for the City to review your quotes and send an official approval letter before your contractor begins any construction. Download our free guide to see the exact step-by-step timeline you need to follow.
Does the grant cover 90% of my entire contractor's bill? ▼
While the grant covers 90% of eligible construction costs, there are strict "caps" on how much you can receive for each item. For example, the maximum for a backwater valve is $1,800, and a sump pit and pump is capped at $4,000. You are responsible for any costs exceeding these limits, though the City offers a 10-year loan for the remaining balance if your property taxes are up to date.
Will this grant pay to fix my finished basement or foundation cracks? ▼
No, the funding is strictly for mechanical flood prevention devices like pumps and valves. It specifically excludes any cosmetic restoration, such as replacing drywall and flooring, and does not cover foundation wall or floor crack repairs. Download our free guide to make sure your contractor’s quote is formatted to focus only on eligible work.
Do I need a permit and an inspection to get paid? ▼
Yes. You or your contractor must obtain the required plumbing or building permits before any work begins, or your grant will be cancelled. Once finished, a City inspector must sign off on the installation while it is still visible; if you bury the work before it is inspected, you will be ineligible for the grant.
My current sump pump is old—can I use the grant to replace it? ▼
No. The grant program does not cover the maintenance, repair, or replacement of existing sump pumps or pits. Funding is only available for brand-new installations designed to disconnect your foundation drains from the City sewer system.
