Home energy performance
There are 30,900 homes with an EPC rating lower than C, which therefore need improvement to meet the Government's home energy efficiency target for 2035 – which the EEIG recommends bringing forward to 2030.
Carshalton and Wallington ranks 469/573 England and Wales Constituencies for the share of homes (9,400) rated C. This is better than the UK average.
It ranks 126/573 for the share of homes (2,900) rated F or G (lower ranking is better). This is better than the UK average:
Home energy investment
30,900 homes below an EPC C rating means 3,100 need to be improved each year to meet the EPC C target for all homes by 2030.
1,281 households have received assistance with energy efficiency measures over the seven years of the Energy Company Obligation (ECO) to the end of 2019. That's 3.3% of households in Carshalton and Wallington, lower than the Great Britain average of 8.0%.
In 2019, 22 households were supported by ECO with a total investment of £70,000.
Number of households supported with ECO
Getting all homes up to EPC C requires investment of £139.1 million by 2030 – £13.9 million per year.
Alongside regulation of minimum energy efficiency standards for the rented sectors, Government should contribute around £45.5 million of this total (£4.5 million per year to 2030). Some of this will continue to come from the Energy Company Obligation. More may come from the Social Housing Decarbonisation Fund and Home Upgrade Grants promised in the 2019 manifesto, to address social housing and some of the 2,900 homes in Carshalton and Wallington rated EPC F or G (i.e. for households on low incomes).
The remainder needs to come from able-to-pay homeowners incentivised by a step-change in government support for energy efficiency investment. Critically, this support is currently missing from existing policy and manifesto commitments.
For example, varying the rate of Stamp Duty to take account of the EPC rating alongside the sale price could incentivise investment by homeowners and help to embed good energy performance in property values.
In Carshalton and Wallington over the last five years, the average number of residential property transactions subject to Stamp Duty was 1,700.
If the properties transacted reflect the Constituency-wide composition of EPC ratings, then 1,300 properties rated D or worse change hands each year and homeowners could – with a Stamp Duty incentive in place – be motivated to improve them.
This could therefore make a significant contribution to the 3,100 properties that need to be improved in Carshalton and Wallington each year to meet the EPC C target by 2030 – alongside rented sector regulation, a properly funded and locally led scheme (potentially Home Upgrade Grants), the ECO, and other incentives.
Getting all homes up to a good level of efficiency would save each household on average £270 per year on their energy bills at current energy prices. This would amount to £8.3 million per year across Carshalton and Wallington once all homes are improved.
The number of economically active people in Carshalton and Wallington is 50,100, of whom 3,000 work in construction. 1,895 economically active people aren't employed. Energy efficiency investment could support employment of 237 people to 2030.
The annual net gross value added from an energy efficiency infrastructure investment programme in Carshalton and Wallington would be £5.6 million. The present value of GVA over the duration of a programme to 2030 would be £46.6 million.
Other benefits not quantified here include increased tax revenues, the avoided (including hidden) costs of unemployment, more spending power, and the latter's impact on the Carshalton and Wallington's economy.
Fuel poverty and excess winter mortality
3,500 households are in fuel poverty: 8.8%, lower than England's average level of 11.1%. This ranks it 150 out of 533 English Constituencies (higher rank is better).
There were 40 excess winter deaths in 2016/17, of which:
12 can be attributed to cold housing conditions
8 can be linked to the coldest 25% of homes in Carshalton and Wallington
4 can be directly attributed to fuel poverty
In 2016/17, there were 21.6% more deaths in winter compared to the non-winter period.
The vulnerability of Carshalton and Wallington to excess winter mortality ranked 241 out of 561 (lower is worse) Constituencies for which data are available.
