  1. Inspect loft insulation depth — Measure depth in several places and note the average depth.
  2. Top up loft insulation to recommended depth — Aim for the manufacturer or local recommended depth (example: ~270mm in many regions).
  3. Check loft ventilation and signs of damp — Ensure vents are clear and look for mould or condensation before adding insulation.
  4. Assess cavity walls for insulation suitability — Check for clues the cavity is already filled or consult building records.
  5. Arrange cavity wall filling if cavities are empty — Hire a qualified installer to inject insulation into empty cavities.
  6. Research external wall insulation options and costs — Compare materials, U-values, installation disruption, and payback periods.
  7. Draught-proof doors and windows — Seal gaps with brushes, weatherstrips, or rebates to reduce cold air infiltration.
  8. Install letterbox and keyhole draught excluders
  9. Insulate floors or add underfloor insulation — Target suspended timber floors or accessible ground-floor voids to cut cold floors.
  10. Lag exposed hot water and heating pipes — Fit foam sleeves on exposed pipes to reduce heat loss and prevent freezing.
  11. Insulate hot water cylinder and tank — Fit a cylinder jacket or top up existing lagging for immediate savings.
  12. Seal gaps and service penetrations — Use sealant or expanding foam around pipe and cable entries and skirting gaps.
  13. Document current energy use and take photos — Record recent bills, thermostat settings, and photos of work areas before upgrades.
  14. Check eligibility for government grants or rebates — Search local schemes or contact your energy advisor for available funding.
  15. Arrange a professional energy efficiency survey — Book an accredited assessor for a whole-house plan and priority fixes.
  16. Compare before-and-after energy bills after 6 months — Track savings, adjust habits, and calculate simple payback for upgrades.
  17. Take safety precautions and stop if asbestos suspected — If your home or insulation is pre-1980, get a professional asbestos check before work.
