Part 03 · The cost

Follow the money when the grass burns

A wildfire’s damage bill is never confined to the burn scar. It spreads — through property losses, insurance, farm incomes, infrastructure and the public budget. The costs land on homeowners, farmers, businesses and the taxpayer, all at once.

Direct losses

What burns first

The first costs are the obvious ones: buildings, stock, equipment and the land itself. During the 2022 heatwave, 41 properties were destroyed in London and at least a dozen more elsewhere [1]. The London Fire Brigade recorded its busiest day since World War Two on 19 July 2022 — 2,670 calls, against a normal ~350[2]. In the first week of August alone, LFB attended 340 grassland and wildland fires, compared with 42 the same week in 2021 — a 700% increase[2].

The direct damage is only the first entry on the bill. In 2022, National Grid peak electricity prices hit £9,724/MWh — 5,000% above the typical level[3] — and the East Coast Main Line was closed. The ripple costs — insurance, markets, infrastructure, relief — often outweigh the direct damage.

What burns next

The less visible damage, and the part that reaches the whole community.

Insurance is the quiet crisis. As fire risk rises, insurers either price it in — pushing rural premiums up — or pull out of the risk entirely, leaving homeowners and farmers underinsured at exactly the moment they need cover most. A region known for fire becomes a region that is harder to insure.

Infrastructure takes a hit too: damaged power lines, railways and roads cut services and complicate the response for the whole region. Businesses that depend on the land — tourism, agriculture, forestry — lose trade while the area recovers, and recovery on moorland and peat can take years.

And water adds a further charge: burn debris pollutes waterways, so the treatment and testing costs fall on the water system that everyone, including fire crews, depends on.

  • 04Public relief & recoveryEmergency housing, food, land repair and peat rewetting are all public costs — paid for from the same budget that funds prevention.
The arithmetic

Why prevention is the cheap option

The numbers always favour getting ahead of a fire. Prevention — fuel management, early detection, and keeping the water system full — costs a fraction of what a single major wildfire costs to fight, rebuild and recover. Australia’s 2019–20 Black Summer fires caused an estimated A$100 billion in damage[4]; the 2019 Flow Country peat fire in Scotland released 700,000 tonnes of CO2e — a carbon debt that will take decades to repay[5].

Where the money goes

Every fire spends public money three times over

First on fighting it — crews, water, equipment. Then on the damage — homes, stock, infrastructure. Then on recovery — land repair, peat rewetting, relief. The only cost that stops all three at once is the one that keeps the fuel wet and the system full: responsible water use.

  • Dry fuel is the cheapest cause and the costliest consequence — and keeping it wet is in our hands.
  • A full water system is cheaper insurance than any premium.
  • Wasted water in a dry summer is a direct cost to the emergency response.
