Solid Wall Insulation Costs & Potential Savings
Did you know that solid walls let through twice as much heat as cavity walls? This means that if your home features solid walls, you could be wasting a considerable amount of energy, which isn’t good news for your pocket or the planet. Fortunately, it’s easy to improve the energy efficiency of solid walls by adding insulation to them, and this can be done both externally and internally. Although this costs more than insulating a standard cavity wall, it can result in greater energy savings.
The insulation comprises a system of specialised panels that are fitted to your walls. In the case of external solid wall insulation, these panels are then covered in special render or cladding. As well as boosting the energy efficiency of your home, this added insulation can make your rooms warmer.
How much does solid wall insulation cost?
Internal and external wall insulation cost can vary considerably depending on the size of the wall you want to cover and the finish you want to have, with prices ranging from £5,500 to £7,500 (excluding VAT)*, this is based on a typical standard 3 bed semi without extensions, standard colour and finish.
When you’re considering solid wall insulation cost, bear in mind that these property improvements will help you to save money over a long time. The average energy bill savings for a semi-detached property are £260** per year, with a life expectancy of over 25 years. In addition, as well as helping to lower your bills, you’ll reduce your household’s carbon footprint. Typical annual carbon dioxide savings for this style of property are 1,100kg.
Meanwhile, because we’re committed to making energy efficiency solutions affordable, we can find out if you are eligible to fund these improvements through the Green Deal scheme or the Energy Company Obligation (ECO) programme, which could help to bring down your external and internal wall insulation cost or upfront costs.
