How much would it cost to make your home greener?

Two thirds of homeowners would like to make energy efficient improvements to their properties, a study from Butterfield Mortgages has found.

Environmental concerns are the greatest driver of change with over half (54 per cent) of respondents saying their worries have led them to consider increasing the energy efficiency of their homes.

But the cost of carrying out improvements such as insulation, heat pumps and double glazing can be high. 

Almost a fifth (17 per cent) of homeowners surveyed said they had considered remortgaging to fund energy-efficient upgrades – in the hope that it would then bring their energy bills down. 

Motivation: Some 46% of homeowners have been driven to make efficiency changes in their homes as a result of spiralling energy costs

Since coming out of the pandemic demand for gas has gone through the roof, but supply has struggled to catch up. It has sent prices soaring and pushed up the cost of gas and electricity for both households and businesses.

This has been compounded by Russia’s invasion of Ukraine which has led to a squeeze on gas supplies across Europe.

However, despite the wholesale price of gas and electricity falling since December household bills are still high.

In the survey, 46 per cent said that the energy crisis and spiralling costs had led them to accelerate their home renovation plans. The figure rises to 65 per cent among people aged between 18 and 34 years old. 

Other are motivated to improve the efficiency of their home in order to increase its future sale value, with 36 per cent saying they are making the changes in order to improve their home’s energy performance certificate rating.

Alpa Bhakta, chief executive of Butterfield Mortgages, said: ‘Homeowners are increasingly looking for ways to improve the energy efficiency of their properties, whether to reduce costs, improve future sale values, or contribute to a greener future. 

‘We can expect millions of owners to invest in home improvements in the months and years to come – and some may be looking to re-finance their property in order to do so.

‘Our research also uncovered a significant knowledge gap among homeowners that needs addressing. Less than half are aware of what the EPC rating of their property is.

‘As sustainability considerations rise, homeowners and buyers alike will be turning to their brokers and lenders for guidance on EPC-related issues, particularly if legislation around residential properties is introduced in the future. 

‘Those who are aware of this growing trend now have an opportunity to become well-versed in the issues ahead of time and can help advise clients appropriately.’

EPC is a rating scheme which bands properties between A and G, with an A rating being the most efficient and G the least efficient. The most common EPC rating for homes in the UK is a D. 

Butterfield’s survey showed that just 40 per cent of homeowners know their property’s current EPC rating.

When asked what they had already done to make their homes greener, the most common improvements were installing LED light bulbs (66 per cent), investing in double or triple glazing (57 per cent), adding loft or wall insulation (55 per cent), and using a smart meter (46 per cent). 

How much do energy efficient home improvements cost?   

For those looking at adding efficiency improvements to your home, it is worth knowing the cost so you can decide what is best for your property.

Double glazing can save you up to £235 a year in energy bills, according to the Energy Saving Trust, keeping heat in and noise and drafts out. However, it comes with an big upfront cost. Fitting A-rated double glazing to the average semi-detached house costs around £7,500.

Keeping more heat in your home through wall or loft insulation is also a popular choice. Around 35 per cent of heat leaves buildings through the walls, according to insulation experts LoftZone.

There are two types of insulation, external and internal. External insulation involves fitting insulating material and then rendering or cladding over it. Internal insulation is mostly a form of thermal sheeting that is fitted to the inside walls. This will reduce room size when installed.

The cost of insulating the outside of a three-bedroom semi-detached home with solid wall insulation is around £12,000, or £8,500 if done inside, according to the Energy Saving Trust.

However, that then leads to a big drop in energy bills – £240 a year for a mid-floor flat all the way up to £930 a year for a detached house.

Cavity wall insulation can save up to £1,800 a year but there can be serious issues if it is not properly installed.

Heat pumps are another way to improve your home’s green credentials. The work by gathering heat from either the air or ground and can replace traditional gas boilers and experts say they can cut up to 25 per cent off your energy bills as the devices require less power to run.

Air source heat pumps can cost between £8,000 and £14,000 to install, according to data from Uswitch.

Meanwhile, ground source heat pumps are generally pricier, with a system costing from £15,000 to £30,000.

What to do if you need a mortgage 

Borrowers who need to find a mortgage because their current fixed rate deal is coming to an end, or because they have agreed a house purchase, should explore their options as soon as possible.

This is Money’s best mortgage rates calculator powered by L&C can show you deals that match your mortgage and property value

What if I need to remortgage? 

Borrowers should compare rates and speak to a mortgage broker and be prepared to act to secure a rate. 

Anyone with a fixed rate deal ending within the next six to nine months, should look into how much it would cost them to remortgage now – and consider locking into a new deal. 

Most mortgage deals allow fees to be added the loan and they are then only charged when it is taken out. By doing this, borrowers can secure a rate without paying expensive arrangement fees.

What if I am buying a home? 

Those with home purchases agreed should also aim to secure rates as soon as possible, so they know exactly what their monthly payments will be. 

Home buyers should beware overstretching themselves and be prepared for the possibility that house prices may fall from their current high levels, due to  higher mortgage rates limiting people’s borrowing ability.

How to compare mortgage costs 

The best way to compare mortgage costs and find the right deal for you is to speak to a good broker.

You can use our best mortgage rates calculator to show deals matching your home value, mortgage size, term and fixed rate needs.

Be aware that rates can change quickly, however, and so the advice is that if you need a mortgage to compare rates and then speak to a broker as soon as possible, so they can help you find the right mortgage for you.

Daisy Lowe’s designer mother Pearl is putting her beachside bolthole up for sale for £1.8million after she transformed it during lockdown

  • Pearl Lowe is selling 1940s Shell House in order to relocate to London

Daisy Lowe‘s mother Pearl has put her beachside home on sale for £1.8million. 

Former singer Pearl Lowe, 53, purchased the Shell House on the East Sussex coast during lockdown but have now decided to sell it up in order to move to London.

The 1940s ‘beach shack’ was built by a soldier who was married to shell artist Theresa Arnott, who crafted the home with seaside-themed installations using shells from nearby Winchelsea beach.

Mrs Lowe and her husband Supergrass’s Danny Goffey, 49 transformed the property, which sleeps 12, after they purchased it in February 2021.

Prior to moving to East Sussex, the couple had lived for seven years in a Georgian manor in Frome, Somerset, the Times reported.

The Shell House has been the setting for many parties, which Mrs Lowe has furnished with luxury fittings including a deVOL Shaker-style kitchen for a ‘vintage’ look, Bert & May-patterned tiles and Burlington bathrooms.

She also added a wildflower path leading up to the cosy self-contained two-bedroom cabin, which comes iwith a log-burner and roll top bath.

But the decor contrasts with her signature pattern clashes and ‘maximalist’ tones, with the designer admitting that a beach house needed to be more ‘basic’.

In March 2022, a pool was installed on the site of a pond along with a steam room and wood-fired tub.

Pearl was visited at the pad by her large family at Christmas – when 18 snuggled into the property.

She has three children with Mr Goffey, Alfie, 27, Frankie, 24 and Betty, 18, as well as her eldest daughter Daisy, with singer Gavin Rossdale.

But the couple are now looking to move to the capital, possibly Hackney, to be closer to their growing family, after Daisy and her partner Jordan Saul had their first child, Ivy, in April.

Mrs Lowe also also rents out the property from £6.650 a week on Unique Homestays, where the home has proved divisive with guests, with some moaning about the rugs with rips in them.

Mrs Lowe described the property as a ‘most enchanting place’ and close to many ‘amazing’ vintage shops including Hawk and Dove, Merchant 57, Xanadu and AG Hendy.

She added that several ‘a-listers’ had visited the pad.

Chemistry Problems & Quantum Computing

The researchers compared the results of a conventional and quantum computer to minimise error calculations, which could eventually be scaled up to solve more complicated problems.

Scientists in Sweden have successfully managed to use a quantum computer to solve simple chemistry problems, as a proof-of-concept for more advanced calculations.

Currently, conventional supercomputers are used in quantum chemistry to help scientists learn more about chemical reactions, which materials can be developed and the characteristics they have.

But these conventional computers have a limit to the calculations they can handle. It is believed quantum computers will eventually be able to handle extremely complicated simulations, which could lead to new pharmaceutical discoveries or the creation of new materials.

However, these quantum machines are so sensitive that their calculations suffer from errors. Imperfect control signals, interference from the environment and unwanted interactions between quantum bits – qubits – can lead to “noise” that disrupts calculations.

The risk of errors grows as more qubits are added to a quantum computer, which complicates attempts to create more powerful machines or solve more complicated problems.

Comparing conventional and quantum results

In the new study by Chalmers University, scientists aimed to resolve this noise issue through a method called reference-state error mitigation.

This method involves finding a “reference state” by describing and solving the same problem on both a conventional and a quantum computer.

The reference state is a simpler description of a molecule that can be solved by a normal computer. By comparing the results from both computers, the scientists were able to estimate the scale of error the quantum computer had in its calculation.

The difference between the two computers’ results for the simpler reference problem was then applied to correct the quantum computer’s solution for the original, more complex problem.

This method allowed the scientists to calculate the intrinsic energy of small example molecules such as hydrogen on the university’s quantum computer.

Associate professor Martin Rahm – who led the study – believes the result is an important step forward that can be used to improve future quantum-chemical calculations.

“We see good possibilities for further development of the method to allow calculations of larger and more complex molecules, when the next generation of quantum computers are ready,” Rahm said.

Research is happening around the world to fix the problems limiting the development of more advanced quantum computers.

Earlier this month, Tyndall’s Prof Peter O’Brien told about his group’s work in addressing a key challenge in quantum technology and how quantum communications will make eavesdropping ‘impossible’.
