The record-breaking heatwave, with 40C peaks, came during a prolonged spell of dry weather - and that dried out gardens, verges and green spaces.
That helped to spark the kind of blazes more commonly seen in the countryside.
More than 40 houses and shops were destroyed after a number of grass fires spread to nearby buildings.
The Met Office estimates that climate change makes the extreme heat seen last week in the UK 10 times more likely. Extreme heat and dry conditions are major factors contributing to wildfires.
According to the National Fire Chiefs Council (NFCC) there have been almost 500 wildfires so far this year alone in England and Wales, compared with 237 last year.
NFCC lead wildfire tactical advisor David Swallow, who is also group commander for Hereford and Worcester Fire Service, said: "Everything is bone-dry and services need to recognise the risk they've now got. If they don't, then they're naïve.
"There are very urban services that think that wildfires are low down on the risk list. I understand the need to prioritise resources, but there needs to be a review."
The wildfire group that Mr Swallow leads draws its members - and expertise - from firefighters in predominantly rural areas more susceptible to such blazes, like Northumberland, South Wales, the Peak District, and Wiltshire.
Mr Swallow believes that every fire service in the UK should have wildfire training. That way, forces could learn valuable tactics from firefighters more familiar with tackling blazes on grasslands, on moors and in woods.
He said that his wildfire group had for some time been preparing for the increased risk of wildfires from climate change but that the risk was now "immediate".
London Fire Brigade assistant commissioner Jonathan Smith said that, following last week's blazes, the service was setting out plans for how it might deal with any increase in such fires.
"This is something the brigade and other emergency services need to be very well prepared and plan for, as we know sadly it's going to happen again," he said.
South Wales Fire Service is seen as leading the way in its approach to wildfires.
Its station manager, Craig Hope, is another of the UK's wildfire tactical advisers. His force keeps specialised lightweight kit, off-road vehicles, a controlled burns team and a helicopter on standby.
However, 5,500 hectares of the Brecon Beacons National Park have already burned in wildfires this year.
"It's horrific, but we have predicted it," he said. "I just don't think anyone would have predicted that it would happen so soon."
He added that years have been spent "making little steps" and that now is the time for "big strides, because the climate is not on our side".
"The fires we are seeing now are what they were getting in Spain in the 80s and 90s."
He urges authorities to invest more in developing a UK-wide "national plan for wildfire".
One solution Mr Hope proposes is that, rather than each force individually spending money on improving its response, there should be funding for a deployable central specialised unit.
Mr Hope added: "The solutions are there. They are complex, but we all need to work together.
"By doing nothing, we risk losing everything."
The BBC went to the Malvern Hills to see the kind of expertise being developed by rural fire crews working alongside landowners.
Duncan Bridges, chief executive for the Malvern Hills Trust, works with the Hereford and Worcester Fire Service to map where the local access points are, and to understand how wind and fire are likely to travel through a landscape.

As part of the trust's wildlife management, the keepers also help to reduce the amount of combustible vegetation, by rolling back bracken and allowing livestock to graze the grass.
Mr Bridges says climate change means the prevention of wildfires is going to become "increasingly more critical".
"There doesn't seem to be any systematic approach across the whole country when it comes to dealing with landowners and land managers," he says. "When dealing with fire prevention and fire safety, it's more a case of each one doing it their own way."
Defra has included wildfire in its national climate adaptation plan, and the Home Office pointed out a plan for England it had published last December outlined plans for "close co-ordination... to provide an effective response to wildfire incidents."
It added: "The government is committed to ensuring fire services have the resources they need to keep us safe, including from wildfires, and, overall, fire and rescue authorities will receive £2.5bn in 2022/23.
