Heating & cooling profile
HotAndCold's model combines the recorded floor area, property type and EPC data, so this 130m² 1990s flat has a current EPC rating of C72 and mains-gas heating. HotAndCold estimates a space-heating requirement of approximately 5.5–7.5kW. Its current EPC performance is relatively strong for an existing home. Its modelled space-heating intensity per square metre is relatively low.

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 3A, GRANGE MANOR, GRANGE ROAD, BROMLEY CROSS, BOLTON, BL7 9AX.
- 1Low energy lighting for all fixed outletsIndicative cost: £115
Replacement of traditional light bulbs with energy saving recommended ones will reduce lighting costs over the lifetime of the bulb, and they last up to 12 times longer than ordinary light bulbs. Also consider selecting low energy light fittings when redecorating; contact the Lighting Association for your nearest stockist of Domestic Energy Efficient Lighting Scheme fittings.
- 2Replace boiler with new condensing boilerIndicative cost: £2,200 - £3,000
A condensing boiler is capable of much higher efficiencies than other types of boiler, meaning it will burn less fuel to heat this property. This improvement is most appropriate when the existing central heating boiler needs repair or replacement, but there may be exceptional circumstances making this impractical. Condensing boilers need a drain for the condensate which limits their location; remember this when considering remodelling the room containing the existing boiler even if the latter is to be retained for the time being (for example a kitchen makeover). It is best to obtain advice from a qualified heating engineer. Ask the engineer to explain the options.

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 5.5–7.5 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?+
