Flood Risk Assessments for Homeowners
Extending, converting or building your own home in a flood zone? We'll tell you honestly what you need, give you a fixed price, and deliver a report the council accepts — without the jargon.
A Straight Answer, a Fixed Price, and a Report That Passes
If you've been told you need a Flood Risk Assessment for your extension, loft or garden room, your first question is usually "do I really?" — and the second is "how much?". We answer both honestly. Send us your address and we'll check the flood zone for free and tell you whether you need an FRA at all. If you do, you'll get a fixed price with no VAT to add, and a report written in plain English that satisfies the council first time.
Most householder FRAs are straightforward: we obtain the Environment Agency's flood data, work out what it means for your property, set the floor level and any simple resilience measures (usually just a flood-resistant door and sensible construction), and write it up in a form the planning officer can approve. Typical householder reports are delivered in 3–5 working days.
You'll deal directly with the consultant doing the work — not a call centre — and you'll get a clear explanation of what the report says and what it means for your project.

Common Homeowner Projects We Help With
If it's on this list, we've done it many times before.
House extensions
Rear, side and wraparound extensions in Flood Zones 2 and 3 — the most common householder FRA, and usually the simplest. From £649.
Garden rooms & outbuildings
Garden offices, annexes and outbuildings that need an FRA because of where they sit, or a drainage statement for their roof.
Conversions & new homes
Barn conversions, garage conversions, annexe-to-dwelling changes and self-build plots — FRAs proportionate to the project.
Buying a house at flood risk
Independent pre-purchase flood risk reviews so you know what you're buying — and what it might cost to protect it.
Which Works Need a Permit — and Which Don't
The permitting system is tiered. Getting your activity into the right tier first is what saves the time and cost.
Not every activity near water needs a full permit. Under the Environmental Permitting Regulations, a flood risk activity is either excluded (no permission needed), exempt (allowed, but must be registered with the Environment Agency), or requires a full Flood Risk Activity Permit. We work out exactly where your proposal sits before any application is made — so you don't pay for a permit you don't need, or get caught out by one you do.
When a permit is needed
Broadly, for works in, over, under or within 8 metres of a main river (16 m for a tidal main river), within 8 metres of a flood defence, or within the floodplain of a main river — including bridges, culverts, outfalls, walls, buildings, bank and bed works, and temporary works.
Main river vs ordinary watercourse
A permit only applies to a designated main river. Works to an ordinary watercourse are consented by the Lead Local Flood Authority instead, through Ordinary Watercourse Consent — so the first step is always confirming which one you're dealing with on the EA's main river map.
What we prepare
Where a permit is required we prepare and submit the application — location and works plans, a method statement, and any hydraulic modelling or flood risk information the EA asks for — and manage the EA liaison through to determination.
