How You Can Lower Your Heating Bill

How You Can Lower Your Heating Bill

The COVID-19 pandemic may have left you wondering how you can save money. We run through how you can effectively reduce your heating bill.

British households typically turn their heating on in October and use it on a daily basis until around March and sometimes even April time, coinciding with the drop in outside temperature, the clocks going back and Winter Fuel Payments. This heating accounts for over 50% of the energy consumed by households.

Broken boiler?

The government’s most recent report shows that 2.4 million households are in fuel poverty. Fuel Poverty essentially means a household cannot afford to keep adequately warm at a reasonable cost, taking their income into account.

How to lower your heating bills

The following points will be covered in this article:

  • Learn how to control your heating and thermostat

  • Insulate your home

  • Stopping draughts

  • Managing radiators

  • Installation of a new boiler

  • Regular boiler servicing

  • Learn to change habits

Although a definitive solution is required to fix this widespread problem, some simple steps can be taken to reduce your energy bills and leave you with more money to spend on fun things for you and your family to go and do!

1. Learn to control your central heating

Control Your Heating

Learning how to control your heating system’s settings to deliver optimum temperature in accordance to your lifestyle can also save you lots of money on your bills. The Centre for Sustainable Energy recommends programming your boiler to turn the heating on 30 minutes before you wake up in the morning but at a lower temperature.

By reducing your room temperature by just 1°C, a change you may not even notice, you could potentially cut your bills by up to £75 a year in an average home. Public Health England suggests 18°C as the minimum temperature of your living room.

2. Insulate your home

Home Insullation

Insulate your home to reduce heat loss through your walls and loft. Almost a third of heat lost in uninsulated homes escapes through the loft/roof. Although loft insulation isn’t cheap, it can save you lots of money in the long run by £160 a year.

3. Stop the draughts

Stop Draughts

Cushion draught excluders are a cheap way to block draughts whilst accessorising your home and can be bought for as little as a pound. Self-adhesive rubber seals for doors and windows are also relatively cheap and easy to install.

Swapping your single glazed windows to double or triple glazed also reduces heat lost through the glass. If this is too costly, even closing your curtains at night can help to create a protective layer of insulation, but make sure to open them during the daytime to make the most of heat from the sun.

4. Stop blocking the radiator

Blocking Radiators

Although having your sofa next to the radiator seems like a great idea, your sofa is in fact absorbing heat that could be warming the rest of the home. Similarly, letting clothes dry and curtains rest on the radiators is preventing the hot air from circulating freely. Reflective radiator panels are also a cheap way to bounce the heat back off the walls into the room.

5. Replace your boiler

Replacing Your Boiler

If your boiler is over 10 years old, it may be time to upgrade to a newer, more efficient model. An A-rated boiler could potentially save you £350 a year. Click here for a fixed quote with 0% finance available for 2 years.

It is difficult to know exactly when you should replace your boiler, and none of us want to spend money if we don't have to, so read our advice on when we feel you should consider replacing your boiler with a newer model.

6. Service your boiler regularly

Service Your Boiler

Although paying for an annual service costs money, having your boiler serviced regularly by a Gas Safe registered engineer such as an iHeat engineer will ensure it is running efficiently and help to prevent it from breaking down, in turn saving you a potential hefty replacement cost. Most boiler warranties also become invalid without a regular service, so take care of your boiler and it will take care of you.

7. Change your habits

Some simple changes to make to reduce your energy bill are:

  • Switch appliances off instead of leaving them on standby as they can still consume 75% of the energy they use when turned on.

  • Switch lights off when you leave the room.

  • Unplug or turn off chargers even if they are not plugged into a device.

  • Only boil as much water as you need.

  • Use extra layers such as clothes or blankets to stay warm.

iHeat New Boiler Costs

Boilers can be a daunting purchase for many people as they’re an appliance with a lot of responsibility, providing heat for you and your family is something you want to get right. Boilers aren’t exactly a quickly disposable item either, potentially lasting you a decade.

Effectively, new boiler cost can be split into two segments: the first is the actual boiler itself (unit price), and the second is the cost of the boiler being installed (set up) in your property by an expert engineer. 

Here at iHeat, we want to remove all of this undue stress and make the decision making process of upgrading to a new central heating system, as easy as possible.

Boiler costs can vary depending on a number of factors including their brand, model, fuel, output, warranty, labour and installation type. Typically a new boiler will cost between £1,845 and £3,500, below is a list of average boiler installations offered by iHeat (guide only).

Frequently Asked Questions

Is it Cheaper to Leave the Heating on All Day?

The consensus among energy experts is that it is not cheaper to leave your heating on all day. It's generally more cost-effective to heat your home only when you need it. Modern thermostats and smart home systems can schedule heating efficiently to ensure your home is warm when required and conserve energy when you're out or asleep.

How Can I Save Heating Costs?

- Insulate your home: Proper insulation in walls, lofts, and around windows and doors keeps heat in, reducing the need for constant heating. - Use a programmable thermostat: Set your heating to turn on only when needed, such as before you wake up or return home. - Service your boiler: Regular maintenance ensures your heating system operates at peak efficiency. - Reduce the thermostat by 1°C: A small reduction can significantly lower your heating bills without affecting comfort. - Draught-proofing: Seal gaps around doors and windows to prevent heat from escaping. - Upgrade your boiler: If your boiler is old and inefficient, consider replacing it with a more energy-efficient model.

How Do I Lower My Central Heating?

Lowering your central heating bill can involve several strategies: - Lower the thermostat setting. - Use TRVs to control the temperature in individual rooms. - Only heat the rooms you use. - Improve home insulation. - Consider investing in a more efficient heating system if yours is outdated.

Does Turning Off Radiators Save Money?

Yes, turning off radiators in rooms you don't use saves money by not heating unnecessary spaces. However, in extremely cold weather, keep all radiators on a low setting to prevent freezing and maintain a consistent temperature throughout the home.

Is it Cheaper to Leave Radiators on Low?

Leaving radiators on a low setting can be more economical than turning them off and on frequently, especially in well-insulated homes where heat retention is high. This method avoids the high energy demand of reheating the whole house from cold.

Is it Cheaper to Keep Radiators on Low All the Time?

Keeping radiators on low all the time can be cheaper in homes with excellent insulation, as it maintains a steady temperature. However, the overall efficiency and cost-effectiveness depend on your home's insulation, the outdoor temperature, and your heating system's efficiency.

How Much Does it Cost to Run Central Heating for 1 Hour?

The cost of running central heating for 1 hour depends on various factors, including the efficiency of your boiler, the cost of your energy (gas or electricity), and the total power output of your heating system. As a rough estimate, for a gas heating system in a medium-sized home, running the central heating could cost between 4 to 6 pence per kWh, depending on your energy tariff and boiler efficiency. For exact costs, you'll need to check your energy prices and consider your boiler's output and efficiency.
