The Benefits of Home Insulation

Ensuring your home is properly insulated could make a big difference when it comes to energy efficiency and lowering your energy bills. Whether you live in a new build house or an older home, adding insulation to the existing structure is a move that pays for itself by helping you save energy at home. 

It can be difficult to know where to start when it comes to insulation, and it’s perfectly normal to wonder ‘how much energy does insulation save?’. Having an energy assessment carried out on your house will help to identify any areas where you’re losing heat, meaning you can choose the ideal home insulation solution for you.

Once installed, you should find that your house feels warmer and more comfortable. Not only that, but you’ll immediately notice your smart meter needs topping up less often. Come the end of the month, you’ll feel a lot more positive about your energy bill.

 

 

Types of Home Insulation

Heat escaping from your home means you’re paying a high price for wasted energy. There are numerous areas where this heat can escape from, and you should consider them all when looking at home insulation solutions. The four main areas where energy can escape from are your roof, walls, floor, and windows and doors.

How Does Loft Insulation Work?

Even though heat can escape in all manner of directions, the general rule is that it travels upwards. This makes roof insulation vitally important when it comes to energy saving. Loft insulation can often be installed by the homeowner, provided the roof joists are accessible and there are no pre-existing issues with damp.

Loft insulation works by inserting mineral wool between the joists, this acts to fill the gaps where heat energy will usually escape and keep it within the home. Whilst it is possible to fit this yourself, it may be worth speaking to a professional installer as, if done incorrectly, it can lead to problems with damp.

How Does Cavity Wall Insulation Work?

Most houses built in the last 100 years will have cavity walls – meaning that the outer walls are made up of two walls with a gap in the middle. Cavity wall insulation aims to fill this gap, avoiding the escape of heat energy which helps keep your house warm as efficiently as possible.

Cavity wall insulation is not a job you can do yourself; it will require a professional to install it. When installing, the cavity walls will be injected with the best type of insulation for your home, this could include polystyrene beads or polyurethane foam amongst others.

How Does Floor Insulation Work?

Stopping heat from escaping through the roof or walls is important, however, to leave the floors without insulation could prove to be a mistake. Note that floor insulation should only need to be carried out on your ground floor.

Floor insulation works by inserting insulation underneath the floorboards, meaning there is nowhere for heat to escape by moving downwards. The type of insulation used will depend on the floor that you have in your home, with new homes often having solid concrete floors and older houses likely to have suspended timber floors.

 

Finding an Insulation Installer

If you do choose to have insulation installed into your home, it’s important that you find the right installer to help guide you on the right choices for you and carry out the work. Any insulation work should come with a guarantee and be carried out by an installer registered with either the National Insulation Association (NIA), the Cavity Insulation Guarantee Agency (CIGA), or the British Board of Agrément (BBA).

 

How Much Energy Does Insulation Save?

Having home insulation fitted comes with many benefits, your house should remain warmer and you’ll rely less on having to turn on the central heating every time you feel a slight chill. All of this means that your smart meter should be giving you lower readings and you’ll be spending less money on your energy bills.

The Energy Saving Trust put together guidance on the average cost of insulation and the money you can expect to save through your investment.

  • Loft Insulation – Owners of a semi-detached house can expect to pay £300 on average for roof and loft insulation. Over the course of a year, you can expect to save £135.
  • Cavity Wall Insulation – The typical installation cost for cavity wall insulation in a semi-detached house is £475. This is based on a gas-heated home and could expect to yield energy savings of £150 a year.
  • Once installed, you should find that your house feels warmer and more comfortable. Not only that, but you’ll immediately notice your smart meter needs topping up less often. Come the end of the month, you’ll feel a lot more positive about your energy bill. 
  • Floor Insulation – The typical installation cost of floor insulation can vary, and it could cost somewhere between £520 and £1,300 depending on the circumstances and work required. In a year, a typical semi-detached house can expect to save £50 from this insulation.

 

Obviously, the amount that you save depends on many different variables, such as the size of your home, type of heating and personal preferences when it comes to temperature. However, what is clear is that insulation presents a lot of opportunities to save on energy and keep your house warm and cosy.

Having insulation fitted in your home is just one way of saving money on your energy bills. Having a smart meter installed by Boost is another option, providing you with a simple way to take control of your energy consumption, alongside simple and easy online payment.

 

Getting help when insulating your home

Investing in home insulation often requires significant upfront cost, and the years it could be until you see a return puts many off making improvements. Still, there are options if you find that the initial cost is just too much.

The Energy Company Obligation (or ECO) is a scheme that supports low income households who are looking to make their home more energy efficient. There are a number of improvements you can get financial help with, one of which is cavity wall and loft insulation.

Head to the government’s energy advice website to find out if you’re eligible for the scheme.  

Alternatively, look to take advantage of the Green Deal. This government-created initiative allows you to install energy efficiencies in your home (including insulation in your walls and loft), paid for with a government-approved loan. This loan is then paid back in pre-agreed installments. You can also combine this scheme with others, such as the Affordable Warmth Obligation, to reduce the overall cost of installation
