When Simon Duffy gets another vigor statement, his heart sinks. “It’s madly expensive,” he says.

Mr Duffy lives in a traditional stone-walled detached house in Sheffield. He estimates that he spends £3,100 every year on heating and electricity.

Despite being someone who cares about climate transformation, and keen to retrofit his property to make it more efficient, there’s a issue.

“The whole question of how to better insulate the house is a real mystery to me,” says Mr Duffy, a director of sustainability ponder-tank Citizen Network. “I don’t recognize where the expertise for that is.” He also adds that he’s also not sure whether he could install solar panels, given that he lives in a conservation area.

Millions of homeowners across the country could be facing the same dilemma.

Around 29 million British homes require retrofitting by 2050, according to the UK Green Building Council, an industry body.

Retrofitting might involve measures such as improving your home’s insulation, upgrading the heating structure, or installing vigor-generating devices such as solar panels, or even a private wind turbine.

These adjustments can expense thousands of pounds up front, but, if properly executed, they could enhance comfort and reduce people’s bills in the long-run.

Plus, increased vigor efficiency ought to cut carbon emissions from homes, especially if property owners switch away from gas or oil-fired boilers, for example.

Roughly one fifth of the UK’s total emissions comes from residential buildings.

Amy tranquility and her husband live in the northwest of England, near Warrington. The pair both work in sustainability, advising businesses on their path to net zero.

They were keen to enhance the standard of their home and apply the principles they promote at work to their own lives – but they too faced challenges when deciding on how to leave about it.

“Even though we’ve got this background, and we’re engineers as well, what we weren’t entirely obvious on was where was best to spend the money,” says Mrs tranquility.

The couple spoke to multiple consultants, but Mrs tranquility found the advice they received was often geared towards conference Passivhaus standards – an ultra-vigor efficient type of building.

“There weren’t many in that pragmatic middle space where you are literally saying, ‘We’ve got this much money, where would we be best putting it?’,” Mrs tranquility adds.

Perseverance during the history three years paid off, however, and the couple’s 1930’s detached house now has improved insulation, a heat pump, and an electric car charging point. Solar panels and battery will pursue shortly, if all goes to schedule.

Conscious of the confusion around approaches to retrofit, some organisations are moving to enhance the advice available to homeowners. Among them is Ecofurb.

“We can model all the different options that are available, suitable for your home and your distribution, and identify a package of measures,” says Liz Lainé, of Parity Projects, a housing data analysis corporation, which runs Ecofurb.

The firm offers this initial consultation for free, but packed plans, with personalised input from a retrofit coordinator, commence at £470. Ecofurb can also oversee any works as they are carried out by contractors to avoid “horror stories”, says Ms Lainé.

There are many other organisations that propose to assist homeowners schedule a retrofit.

The work often involves carrying out a heat-deficit survey, to spot cold areas that require insulation, and to better comprehend a property’s heating demand. Experts might also advise on the suitability of solar panels for your home, for example.

There’s the Get a Heat Pump website, launched by the charities Nesta and The MCS Foundation, which explains what heat pumps are and how they might fit into a home renovation schedule.

RICS, the Royal Institution of Chartered Surveyors, has also just launched a recent retrofit standard for its members – essentially, it encourages surveyors with the appropriate training to propose their services to homeowners planning or undergoing a retrofit.

The RICS website will soon include a range of retrofit advice and a tool to assist homeowners discover a suitable surveyor in their local area, says Steve Lees, from the RICS retrofit assignment throng.

Improving the vigor efficiency of homes is “essential” for decarbonisation, says Gerald Charles, head of housing retrofit at the Centre for Sustainable vigor, but he adds that the current lack of excellent advice remains a genuine issue.

“The industry as a whole don’t appreciate the importance of excellent retrofit advice,” he says.

One business owner who has noticed a knowledge gap in the trade is James Major, founder and chief executive of HubbPro, which helps architects schedule vigor efficient buildings. Architects don’t always have the latest information about how to incorporate vigor-saving technologies into their designs, notes Mr Major.

“tidy tech isn’t part of what they do or what they should recognize – that’s an engineering function,” he says. And yet architects’ clients increasingly inquire about such tech when planning a recent home or an extension.

Through an initiative called MyHubb, Mr Major is now offering architects detailed reports that approximate the carbon reduction potential and payback period on retrofitted measures – such as heat pump-based heating systems or solar panels, for instance.

He says these reports expense around £1,000, though he adds that this worth is not yet finalised.

Mr Duffy says he will keep looking for solutions to his own retrofit conundrum. But he makes another point. So much of the currently available technology and advice is tailored to person homeowners.

He suggests that neighbourhood-scale schemes, for example to provide solar power to a whole street, might make more sense and could include more people in one leave.

“That’s what I would ponder is the logical way of thinking about this,” he says.
