Older homes are more likely to have solid walls and less original insulation — this shapes your plan.

The recommended depth is 270mm. Thinner insulation is worth topping up — cheap and done in a day.

Most homes built before 1990 with no previous retrofit work have uninsulated walls. If unsure, we will include it in your plan.

Methodology & the fabric-first principle

This quiz applies the fabric-first principle — the cornerstone of PAS 2035, the UK whole-house retrofit standard, and endorsed by the Energy Saving Trust. The principle: reduce the heat your home loses before you invest in a better way to heat it or generate your own energy.

Insulation and draught-proofing come first. A poorly insulated home wastes a heat pump's output just as readily as an old boiler's. Once the fabric is tight, a smaller, cheaper heating system does more work — and any solar panels added later generate surplus rather than merely chasing a leaky building.

How recommendations are ranked:

  • Loft insulation — cheapest, fastest, often grant-funded. Top priority if absent or thin.
  • Draught-proofing — very cheap, high perceived comfort gain. Always recommended.
  • Wall insulation — cavity wall (CWI) for post-1920 homes; solid wall (IWI/EWI) for older properties.
  • Heating system upgrade — heat pump recommended once fabric is well insulated, especially for oil/LPG homes.
  • Solar PV — recommended for detached/semi/bungalow owners targeting bills or carbon.
  • EPC uplift — flagged where the goal is selling or letting.
