Local authorities were forced to deal with 1.13 million cases of rubbish dumped on highways and in beauty spots in 2020/2021, up from 980,000 the previous year.
Household waste accounted for 65% of the incidents – around the same proportion as 2020/2021.
Debris was most commonly dumped on pavements and roads, making up 485 of every 1,000 cases, followed by footpaths and bridleways at 198 in every 1,000, the Government said.
The South West was the cleanest, with 10 cases per 1,000 people.
The most common quantity of rubbish to be dumped was equivalent to a small van load, accounting for 34% of total cases, followed by a load of a car boot size or less at 26%.
Around 39,000 cases of dumped waste were classed as enough to fill a tipper lorry, making up 4% of the total and up from 16% in 2019/2020 when this figure was 33,000.
Clearing up all the large fly-tipping incidents cost local authorities in England £11.6 million, up from £10.9 million the previous year.
Despite the rise in cases, the number of enforcement actions carried out by councils fell by 4% to 456,000, compared to 474,000 in 2019/2020.
The number of fixed penalty notices dropped by 24% to 57,600 in 2020/2021 from 75,400 the year before.
Meanwhile the number of court fines issues dropped by 51% to just 1,313 from 2,672 in 2019/2020 – with the total value of the fines decreasing by 62% to £440,000 from £1.2 million last year.
Explaining the data, the Government noted that last year’s figures covered the first national coronavirus lockdown imposed in March 2020, which impacted many local authorities’ recycling programmes.
Some suspended collection of dry recycling, and others also pausing garden and bulky waste collection.
There were also widespread closures of household waste recycling centres, although many later reopened following updates to social distancing guidance.
Changes to household purchasing during lockdown, as well as changes to travel and leisure may also have driven the increase in fly-tipping, the Government said.
Staff shortages within local authorities, staff being furloughed or redeployed may also have reduced the number of investigations that were conducted.
Many local authorities reported that closures to courts at a certain point over the last year’s lockdowns impacted the number of prosecution actions undertaken.
The Country Land and Business Association (CLA), which represents rural businesses in England and Wales remarked that the figures probably only tell half the story, as they only cover fly-tipping on public land.
It said the “vast majority” of fly-tipping occurs on private land, with one of its members facing a £100,000 bill to clear up just one incident.
Mark Tufnell, president of the CLA, said: “These figures do not tell the full story of this disgraceful behaviour which blights our beautiful countryside.
“Local authorities tend not to get involved with clearing incidences of fly-tipped waste from private land, leaving the landowner to clean up and foot what is often an extortionate bill.”
He continued: “Fly-tipping continues to wreck the lives of many of us living and working in the countryside – and significant progress needs to be made to stop it.
“It’s not just the odd bin bag but large household items, from unwanted sofas to broken washing machines, building materials and even asbestos being dumped across our countryside.”
