Energy-efficient home improvements can significantly boost property value - Global Banking & Finance Review — Image illustrating energy-efficient home upgrades that can increase property value by nearly £25,000, as discussed in the article about the impact of energy ratings on UK homes.

MoneySuperMarket reveals the effect of energy ratings on property prices around the UK
While some locations see little benefit, others can see increases of up to £24,766 on the average local property prices
Increasing your energy rating can be as easy as replacing traditional light bulbs with energy efficient ones

When attempting to sell your property, you want to do everything you can to make it an attractive purchase.

A new coat of paint, making repairs and tidying up are all usually on the list, but have you considered improving your energy rating? MoneySuperMarket has found that upgrading your Energy Performance Certificate (EPC) – the government’s rating of a property’s energy efficiency – from an average D to a high end A can have massive financial benefits.

The research explores different locations in the UK and how changes to your EPC affect the price of local properties. An EPC incorporates the type and layout of the building, any heating, cooling, ventilation and hot water systems used, and the lighting. The startling results show that an increase from the lowest rating, G, to as little as F can have a six per cent price increase on average – while raising it to an A or B can give a 14 per cent boost to your potential sale price[i].

Regional Improvements

The differences in price vary across the UK, meaning that although properties in the North East could see benefits of up to 38 per cent by increasing their EPC from a G rating to an A or B, those in the South East will see none at all[ii]. Cities that could benefit the most include:

Lichfield – Houses in Lichfield sell for an average of £265,000, but given that the average UK EPC rating is only a D, those looking to increase the price of their properties could see an increase of £24,766 by raising that rating to an A or B
York – With an average sale price of £269,997, sellers can benefit from an increase of £23,684 on average by increasing their rating to an A or B
Bristol – Bristol properties sell for £285,000 on average but could reach £306,923 with an increased rating
Worcester – Simple improvements on energy resources around a Worcester house can result in a £21,028 increase
Exeter – Exeter sellers could add £20,769 to their average house price of £270,000 by increasing their energy ratings[iii]

Improve your EPC Rating

In order to access these increases to your property value – and even save money on a property you’re holding onto – you need to know how to improve your EPC rating. Here are some suggestions on where to start looking to make the most of your energy:

Install insulation – cavity wall insulation not only offers a chance to improve your energy efficiency, but can also save you £160 a year while you live in the property, which can quickly offset initial costs[iv].
Lagging jackets – these are insulation for your water pipes. They can greatly improve the efficiency of your hot water tank.
Light-bulb replacement – something as simple as using energy saving bulbs instead of traditional ones can improve home energy efficiency with minimal effort.
Upgrade your boiler – particularly in cases where your property features an older boiler, a newer one can have a significant effect on the efficiency of your property.
Review your EPC – if you have an existing EPC, this offers specific ways that the energy efficiency of a property can be improved.

Stephen Murray, energy expert at MoneySuperMarket, said: “Improving your energy rating can significantly increase your sale price for a relatively low cost. But it’s also valuable for other homeowners who aren’t planning to sell their properties, as a higher energy rating means greater home efficiency and reduced energy bills.

“With relatively simple changes such as insulation, lagging pipes and 6energy efficient light bulbs, you can not only increase your property price for sale, but also reduce your energy bills while you live in it. Those looking to stay for a longer time will see greater benefits from investing in insulation, or in renewable energy sources such as solar panels and biomass boilers. We fully recommend looking into all the ways to increase your EPC and then getting an updated certificate to reflect the improvements.”
