Energy Efficiency in Older Homes: Smart Savings Tips

Why Is Energy Efficiency Important in Older Homes?

Improving energy efficiency in older homes isn’t just about saving pennies – it’s about pounds! Here’s why it matters:

1. Lower bills: The average UK household spends £1200 to £1500 a year on energy. In older homes, this can be much higher.
2. Cosier living: Say goodbye to drafts and cold spots.
3. Reduced carbon footprint: The UK’s homes account for about 15% of the country’s carbon emissions.

What Are the Common Energy Efficiency Challenges in Older Homes?

Older homes often face a few hurdles when it comes to energy efficiency:

Insulation Issues

Many older homes have little to no insulation. In fact, about 35% of heat in an uninsulated home is lost through the walls.

Drafty Windows and Doors

Single-glazed windows can lose twice as much heat as double glazing. Gaps around doors can make your heating work overtime.

Inefficient Heating Systems

An old boiler could be operating at just 60% efficiency, compared to 92% for a new A-rated boiler.

Air Leaks

Small gaps and cracks can add up. They could be letting out as much warm air as an open window!

How to Improve Insulation in Older Homes

Proper insulation is like a warm jumper for your house. Here’s how to wrap up:

Types of Insulation

1. Loft insulation: You could save up to £315 a year by topping up your loft insulation to 270mm.
2. Wall insulation: Cavity wall insulation can save you around £180 a year.
3. Floor insulation: This can save you about £75 a year on your energy bills.

DIY vs. Professional Installation

While some insulation jobs are DIY-friendly, others need a pro. For example, cavity wall insulation should always be done by a certified installer.

Tip: Always check for damp issues before adding insulation. Trapping moisture can lead to bigger problems down the line.

How to Upgrade Windows and Doors for Better Efficiency

Upgrading your windows and doors can make a big difference:

Double Glazing

Double glazing can cut heat loss through windows by half. It could save you around £110 a year on your energy bills.

Sealing and Draft Proofing

Simple draft-proofing measures around windows and doors could save you £45 a year. That’s not to be sniffed at!

How to Improve Heating Systems in Older Homes

An efficient heating system is crucial for keeping those bills down:

Upgrading Boilers

Replacing an old G-rated boiler with an A-rated one could save you up to £300 a year.

Radiator Maintenance and Upgrades

1. Bleed your radiators regularly to keep them working efficiently.
2. Install thermostatic radiator valves (TRVs) to control the temperature in each room. This could save you £75 a year.

Tip: Consider a power flush for your heating system every 5-6 years to keep it running efficiently.

What Are the Financial Incentives for Improving Energy Efficiency?

Don’t let the cost put you off – there’s help available:

Government Grants and Subsidies

The Green Homes Grant scheme might be closed, but other options are available:

1. Energy Company Obligation (ECO) scheme: Free insulation and boiler upgrades for eligible households.
2. Renewable Heat Incentive (RHI): Payments for installing renewable heating systems.

Energy Company Schemes

Many energy suppliers offer free or discounted insulation. It’s worth checking with your provider.

How to Monitor and Maintain Energy Efficiency Improvements

Once you’ve made improvements, keep them working well:

Regular Maintenance Tips

1. Service your boiler annually.
2. Check your insulation for any signs of damage or settling.
3. Clean your windows and check seals regularly.

Using Smart Technology

Smart thermostats can save you up to £75 a year on your energy bills. They learn your routine and adjust heating accordingly.

What About Listed Buildings and Conservation Areas?

Improving energy efficiency in listed buildings or conservation areas can be tricky, but not impossible:

1. Secondary glazing: A good alternative to double glazing for listed buildings.
2. Breathable insulation: Materials like sheep’s wool work well with older buildings.
3. Draught-proofing: Often allowed even in listed buildings.

Always check with your local conservation officer before making changes.

How Can Renewable Energy Fit into Older Homes?

Renewable energy isn’t just for new builds:

1. Solar panels: Can be installed on many older roofs, saving around £270 a year on electricity bills.
2. Heat pumps: Air source heat pumps can work well in older homes with good insulation.
3. Biomass boilers: A good option for homes off the gas grid.

How to Reduce Your Gas and Electricity Bills in Older Homes

Cutting your energy bills in an older property can seem daunting, but there are plenty of ways to save. Here’s how you can reduce your gas and electricity usage without compromising on comfort:

Tackle Your Home’s Weak Points

1. Insulate your hot water cylinder: A well-insulated cylinder jacket can save you £35 a year on bills.
2. Address solid walls: External or internal wall insulation can save up to £350 annually on heating costs.
3. Don’t forget the attic: Proper loft insulation can prevent up to 25% of your home’s heat from escaping through the roof.

Smart Usage of Appliances

1. Washing machine wisdom: Washing at 30°C instead of higher temperatures can save you £25 a year.
2. Kettle know-how: Only boil the amount of water you need to save £8 a year on your electricity bill.
3. Plug out: Appliances left on standby can cost up to £35 a year in wasted electricity.

Regional Support and Advice

Different parts of the UK offer varied support:

• In Scotland, Home Energy Scotland provides free, impartial advice on energy saving.
• For Northern Ireland, the Warm Home Discount scheme offers £150 off electricity bills for eligible households.
• In England and Wales, the Energy Company Obligation (ECO) scheme provides support for energy efficiency measures.

Dealing with Damp and Ventilation

Damp walls can increase heating costs by up to 50%. Proper ventilation is crucial:

1. Use extractor fans in bathrooms and kitchens.
2. Consider a positive input ventilation system for whole-house benefits.
3. Address any underlying damp issues to prevent mould and rot.

The Importance of EPCs

An Energy Performance Certificate (EPC) can provide valuable insights:

• It rates your home’s energy efficiency from A (most efficient) to G (least efficient).
• It offers recommended improvements to boost your home’s rating.
• As of October 2023, all rented properties in England and Wales must have an EPC rating of at least E.

Tackling Older Features

1. Chimneys: A chimney balloon can prevent heat loss when the fireplace isn’t in use, saving up to £75 a year.
2. Solid floors: Insulating a solid floor can save around £40-£90 annually on heating bills.
3. Window frames: Draught-proofing window frames can save £45 a year on energy bills.

Compare Gas and Electricity Prices Regularly

One of the simplest ways to cut your gas and electricity bills is to ensure you’re on the best tariff:

1. Shop around: Use comparison websites to check if you could save by switching suppliers.
2. Fixed vs. variable rates: Fixed-rate tariffs can protect you from price hikes, while variable rates might offer savings if energy prices fall.
3. Dual fuel discounts: Some suppliers offer discounts if you get both gas and electricity from them.
4. Green tariffs: These support renewable energy and can sometimes be cheaper than standard tariffs.
5. Check for exit fees: Be aware of any charges for leaving your current contract early.

How can I improve ventilation in my older home without losing heat?

Proper ventilation is crucial for older homes, but it shouldn’t come at the cost of warmth. Consider installing trickle vents in windows or a positive input ventilation system. These allow fresh air in while minimising heat loss. In bathrooms and kitchens, use humidity-controlled extractor fans to remove moisture without over-ventilating.
