Heating costs continue to rise across the UK, and one of the cheapest ways to save money is by improving your home’s insulation. A well-insulated house loses less heat, keeps rooms warmer in winter, cooler in summer, and lowers energy bills.

The good news? You don’t need a huge budget to start making improvements. Here are the best DIY insulation tips UK homeowners can try on a budget — plus how Sort a Home can connect you with trusted professionals if you need extra help.

Why Insulation Matters in UK Homes

• Up to 35% of heat loss comes through walls and roofs.

• Poor insulation leads to higher bills and uncomfortable draughts.

• Even cheap DIY insulation can save £100s a year on heating.

1. Loft Insulation on a Budget

• Heat rises, so insulating your loft is one of the most cost-effective upgrades.

• DIY loft rolls start from around £20 per pack and are simple to lay between joists.

• Focus on insulating to at least 270mm thickness, which is the UK standard.

2. Draught-Proofing Doors and Windows

• Cold air sneaks in through gaps in doors and windows.

• Cheap fixes include:

  • Self-adhesive foam strips.

  • Draught excluders at the base of doors.

  • Silicone sealant for window frames.

• Many solutions cost less than £10–£15.

3. DIY Pipe and Tank Insulation

• Wrap exposed pipes with foam lagging to stop heat escaping.

• Insulate water tanks in lofts with a jacket (around £20–£30).

• Prevents frozen pipes and improves heating efficiency.

4. Secondary Glazing Film

• Full double glazing can be expensive, but plastic glazing film is an affordable alternative.

• Stick-on film creates a barrier against draughts and heat loss.

• Ideal for rented homes or temporary fixes.

5. Radiator Reflector Panels

• Place reflective foil panels behind radiators on external walls.

• This bounces heat back into the room instead of losing it through walls.

• Cheap packs start from £5–£10 and are easy to fit.

6. Insulate Floors with Rugs and Mats

• Wooden or laminate floors let heat escape.

• Thick rugs or budget underlay reduce draughts and keep rooms warmer.

7. Use Curtains and Blinds Wisely

• Thick thermal curtains help trap heat.

• Close them at night and open them in the day to use natural sunlight.

8. DIY Wall Hangings

• Hanging large tapestries, blankets, or fabric wall panels adds a layer of insulation.

• A cheap, creative way to keep draughty walls warmer.

Extra Budget Tips

• Close unused rooms to save heat.

• Move furniture away from radiators for better airflow.

• Use draft stoppers and door snakes.
