Cut Your Energy Costs

The following section provides a homeowners guide to energy performance improvements. It is financially beneficial to consider energy performance at the same time as you are carrying out home improvements. It also prevents further disruptions following the refurbishments.

This section focusses on living spaces such as lounge, dining room, bedrooms and bathrooms. You may notice some rooms are colder than others, or susceptible to unwanted draughts. This makes it very difficult to maintain temperatures in the winter. The measures highlighted below will save you money on your bills, help reduce the carbom emissions of your home and improve its quality and comfort. 


 

Add energy efficienct measures as you improve your home

Draught Proofing

This is one of the chepaest and most efficient ways you can save energy. It's important to minimise heat loss from draughts coming in through floors, walls, around service pipes and cables, and around windows and doors.

At the same time, you must maintain the right levels of ventilation in the home, especially if you have rooms with open fires or open flures. 

Floor

Floor insulation is an ideal opportunity to prevent your feet getting cold in winter. About 15% of a home's heat loss is through the floor.

If you have a timer floor, the most efficient option is for your builder to lift floorboards and install insulation between the floor joists. If you have a solid foor, insulated floorboards are laid on top of your existing floor, slightly raising the floor level. If you're having more extensive work carried out, the top layer of the floor can be removed and insulation added to preserve the existing floor level. 

Lighting

Low energy compact flourescent lights (CFLs) save power, whilst performing as well as traditional bulbs. High-powered LEDs are now widely available, have improved dramatically in recent years, and are particularly suited to task lighting and spotlights. If you intend to install new lighting, building regulations require 75% of all bulbs to be low energy. 

Walls

Up to 35% of heat escapes through walls - so adding insulation will be a big factor in making your home much more cosy. 

If your home was built after 1920, the chances are it has cavity walls made of two layers with a small gap between them. They can easily be fitted with insulation. If your cavities have not already been filled, you may be able to treat the whole house for around £250 and save up to £110 per year on heating bills. Homes with solid walls have no gap. So even more heat escapes than through cavity walls. External wall insulation and/or internal wall insulation can be applied to the whole house but the total cost is higher than for a house with cavity walls. 

Windows

Just like appliances and houses, windows are rated on an A to G scale. C-rated windows are now a minimum requirement in building regulations, but windows with a higher rating will perform even better. 

Recommended products

There are many energy efficient products on the market. But the best of the best are those which carry the Energy Saving Trust Recommended logo- your assurance that these meet the strictest criteria and deliver the biggest energy savings. 

Steps to an energy efficient home

By adding measures at the same time work is being doe allows you to future proof your home against energy price increases. Adding energy efficient measures as you renovate each home will increase its overall efficiency making it more comfortable and gradually reducing your energy bills. In addition, you will also improve the overall EPC rating of your home, making it more attractive to a future buyer.
