Whether you’re looking to make improvements before you have your EPC done, or are following the recommendations after getting it done, these improvements always seem to be a little expensive. At EPC Bromley we feel that this needn’t be the case.
The improvements that are going to have to greatest effect on your energy efficiency rating are things such as a new boiler (up to and sometimes over £1,000); solid wall insulation (£4,000-£10,000, depending on the size of your property); and Solar PV (around £6,000 – £9,000).
These aren’t exactly cheap but each one will give you a significant improvement on your energy efficiency. You might even be considering the dreaded but often weirdly recommended solid floor insulation. A massive expense, a huge upheaval but for very little reward, why it’s constantly recommended is anyone’s guess? The recommendation from EPC Bromley is not to bother with this.
The cheapest and one of the most effective ways to make your home more energy efficient is draught proofing. Remember, there are two considerations when you are trying to make your house warmer. Firstly, what it says on paper, secondly, what makes it feel warmer. Draught proofing definitely fits into the second category, especially on houses built in 1939 or before.
Where do you need to draught proof?
- Doors and Windows – The edges are the most obvious places but don’t forget about letterboxes and keyholes. If you aren’t able to install double glazing or can’t afford to, then remember that secondary glazing can be just as effective.
- Suspended floorboards – Most houses pre 1930s will be built on suspended floorboards. Make sure the gaps are sealed in between the floorboards, check whether there are any gaps between skirting and floor.
- Chimneys – If you have a chimney that is not in use then ensure that it is sealed up properly. Ensure there are no gaps.
- Pipework and electrics – Sometimes holes have been drilled through walls to allow pipes or cables through. Ensure that all of these holes are filled in and that no warm air can escape.
- Loft hatch – An often forgotten part to insulate when loft insulation is done as a DIY project. Don’t only insulate the loft hatch, but ensure that the edges are also protected.
What does EPC Bromley recommend when it comes to draught proofing?
Although draught proofing can be done relatively cheaply, it is still important to make sure you use an effective product in every area.
Remember that window frames and floor boards made of wood will expand and contract as they heat and cool every day, so a material that can tolerate this movement is important. Wooden frames can sometimes warp too, leaving irregular gaps to fill, a product that can fill these gaps is important to consider as well.
Why is draught proofing important?
Warm air is attracted to cold air, if there is a gap to the outside then warm air will be sucked out of it, meaning your heating will have to work even harder to warm your home to the temperature you desire. Not only is this energy consumption bad for the environment, it’s also costing you money.
EPC Bromley recommends popping down your local DIY shop and investing small for a potentially larger gain.
