Heating & cooling profile
From the available property and energy data, this 45m² pre-1900 flat has a current EPC rating of D64 and mains-gas heating. HotAndCold estimates a space-heating requirement of approximately 4.5–5.5kW. This property has moderate recorded energy efficiency — neither especially poor nor especially high. Its modelled space-heating intensity per square metre is relatively high.

Energy improvement potential
Recommended improvements for this property
Measures from this home’s official Energy Performance Certificate assessment that could raise its rating and cut running costs, specific to FLAT 2, 26 FROGHALL LANE, BEWSEY AND WHITECROSS, WARRINGTON, WA2 7JR.
- 1Increase loft insulation to 270 mmIndicative cost: £100 - £350
Loft insulation laid in the loft space or between roof rafters to a depth of at least 270 mm will significantly reduce heat loss through the roof; this will improve levels of comfort, reduce energy use and lower fuel bills. Insulation should not be placed below any cold water storage tank; any such tank should also be insulated on its sides and top, and there should be boarding on battens over the insulation to provide safe access between the loft hatch and the cold water tank. The insulation can be installed by professional contractors but also by a capable DIY enthusiast. Loose granules may be used instead of insulation quilt; this form of loft insulation can be blown into place and can be useful where access is difficult. The loft space must have adequate ventilation to prevent dampness; seek advice about this if unsure (particularly if installing insulation between rafters because a vapour control layer and ventilation above the insulation are required). Further information about loft insulation and details of local contractors can be obtained from the National Insulation Association (www.nationalinsulationassociation.org.uk).
- 250 mm internal or external wall insulationIndicative cost: £4,000 - £14,000
Solid wall insulation involves adding a layer of insulation to either the inside or the outside surface of the external walls, which reduces heat loss and lowers fuel bills. As it is more expensive than cavity wall insulation it is only recommended for walls without a cavity, or where for technical reasons a cavity cannot be filled. Internal insulation, known as dry-lining, is where a layer of insulation is fixed to the inside surface of external walls; this type of insulation is best applied when rooms require redecorating and can be installed by a competent DIY enthusiast. External solid wall insulation is the application of an insulant and a weather-protective finish to the outside of the wall. This may improve the look of the home, particularly where existing brickwork or rendering is poor, and will provide long-lasting weather protection. Further information can be obtained from the National Insulation Association (www.nationalinsulationassociation.org.uk).
- 3Flat roof or sloping ceiling insulationIndicative cost: £850 - £1,500
Insulation of a flat roof or sloping ceiling will significantly reduce heat loss through the roof; this will improve levels of comfort, reduce energy use and lower fuel bills. Where the weatherproof membrane is sound and the roof construction is appropriate, suitable insulation can be placed on top of the roof membrane (inverted roof). Alternatively, where the weatherproof membrane needs to be replaced insulation can be provided under the weatherproof membrane (warm roof). Further information about roof insulation and details of local contractors can be obtained from the National Insulation Association (www.nationalinsulationassociation.org.uk).
- 4Upgrade heating controlsIndicative cost: £350 - £450
A room thermostat will increase the efficiency of the heating system by enabling the boiler to switch off when no heat is required; this will reduce the amount of energy used and lower fuel bills. Thermostatic radiator valves should also be installed, to allow the temperature of each room to be controlled to suit individual needs, adding to comfort and reducing heating bills provided internal doors are kept closed. For example, they can be set to be warmer in the living room and bathroom than in the bedrooms. Ask a competent heating engineer to install thermostatic radiator valves and a fully pumped system with the pump and the boiler turned off by the room thermostat. Thermostatic radiator valves should be fitted to every radiator except for the radiator in the same room as the room thermostat. Remember the room thermostat is needed as well as the thermostatic radiator valves, to enable the boiler to switch off when no heat is required. It is best to obtain advice from a qualified heating engineer.

Common questions
How much does a replacement boiler cost for a property like this?+
For this property we estimate an installed cost of £1,900–£3,200. This is indicative and based on the property's size, type and energy characteristics — your final price depends on equipment choice and an installer survey.
What size boiler might this property need?+
Our preliminary model estimates a heat requirement of around 4.5–5.5 kW. An installer confirms exact sizing on a heat-loss assessment.
How much would air conditioning cost here?+
A multi-split installation is estimated at £3,800–£5,700, depending on how many rooms you want to cool (around 3 indoor units in a typical layout).
Are these guaranteed prices?+
No — they are indicative estimates to help you understand likely costs before speaking to an installer. Your final price depends on equipment choice, installation complexity and a survey.
