It’s that time of year again. The temperature has dropped, the heating is cranking up, and you just know that next energy bill is going to be painful.
If you’re sitting in a draughty room right now wondering why you can’t get warm, the answer is usually simple: heat escapes fast. In fact, a poorly insulated home loses up to 25% of its heat through the roof and another 35% through the walls.
That means for every hour your heating is on, you are effectively paying to heat the air outside your house.
The good news? You don't need a massive renovation to fix it. There are high-impact jobs you can tackle this very weekend to immediately trap heat and lower bills.
Better yet, because we are Next Day Insulations, you don't have to wait weeks for materials. Order today, and you could be starting the job tomorrow morning.
Here are three ways to stop the heat loss fast.
1. The "Weekend Warrior" Win: Topping Up Loft Roll
If your loft floor looks like bare wooden joists with just a thin layer of old, dusty fluff between them, you are losing hundreds of pounds a year.
Current regulations recommend a total depth of 270mm of mineral wool insulation. Most older homes have less than half of that.
The Fix: This is the easiest DIY win. Simply buy new rolls of mineral wool (like Knauf Earthwool or Isover Spacesaver) and roll it out right over the top of the existing insulation, running crossways over the joists. It’s like putting a thick woolly hat on your house.

2. The Cold Wall Cure: PIR Insulated Plasterboard
Do you have external walls that feel freezing to the touch? Solid brick walls (common in pre-1930s houses) are notorious for sucking heat straight out of a room.
The Fix: Instead of messy, expensive external cladding, use Insulated Plasterboard. This is a clever 2-in-1 product: a high-performance PIR insulation board (like Celotex or Kingspan) bonded directly to a plasterboard front.
You fix these sheets to the inside of your cold wall using drywall adhesive (dot and dab) or mechanical fixings. You lose a tiny bit of room space, but the difference in warmth is instantly noticeable.

3. The Hidden Heat Thief: Gaps and Drafts
Sometimes it's not the big surfaces, but the small gaps causing the chill. Gaps around pipework, loft hatches, and behind skirting boards create a "chimney effect," pulling cold air in and sucking warm air out.
The Fix: Don't ignore the accessories. Grab some Expanding Foam to seal larger gaps around pipes entering walls, and use quality Foil Tape to seal joins between existing insulation boards to ensure an airtight barrier.
