  1. 1

    Enter Your Home's Floor Area

    Measure the total heated floor area in square metres. Include all rooms that require heating. For multi-storey homes, add all floor levels together. Typical UK home: 75-150 m² (terraced/semi-detached), 150-250 m² (detached).

  2. 2

    Select Your Heating Type

    Choose your current heating system: Gas boiler (most common in UK), oil boiler, electric heating, heat pump, or solid fuel. Each has different efficiency and fuel costs. Gas combination boilers are most prevalent in British homes.

  3. 3

    Choose Insulation Level

    Rate your home's insulation: Poor (pre-1950s solid wall, single glazing), average (cavity walls, double glazing), good (modern insulation, A/B-rated windows). Check loft insulation depth - should be at least 270mm for good rating.

  4. 4

    Set Desired Indoor Temperature

    Enter target temperature: 18-21°C recommended for living areas, 16-18°C for bedrooms. Each degree higher increases heating costs by approximately 10%. Most UK households maintain 19-20°C in winter.

  5. 5

    Input Local Climate Data

    Enter your region's average winter temperature and heating degree days. UK averages: South 4-6°C, Midlands 3-5°C, North/Scotland 2-4°C. Colder climates require more heating energy and have longer heating seasons.

  6. 6

    Review Results and Savings Options

    Calculator shows annual heating cost in pounds, energy consumption in kWh, and CO2 emissions. Compare different scenarios: improving insulation, upgrading boiler efficiency, or switching to heat pump. Identify highest-impact improvements for your situation.
