A Heating Upgrade Roadmap for Derby Homes with High Energy Bills

Understand Why Your Derby Home Is Using So Much Energy

Before making substantial changes, begin with the evidence. Look at recent gas and electricity bills and compare consumption across different periods rather than looking only at the amount paid.

Energy prices can change, so a higher bill does not automatically mean the property is consuming more energy.

What should you check?

• Annual energy consumption in kWh
• Current Energy Performance Certificate
• Heating schedules and thermostat settings
• Rooms that cool faster than others
• Existing roof, wall and floor insulation
• Noticeable draughts or cold surfaces

Address Simple Heat Loss Before Increasing Heating Output

One practical way to improve comfort is to prevent unnecessary heat from escaping.

This is particularly important where the heating system runs for long periods but rooms cool quickly after it switches off.

• Gaps around external doors
• Poorly sealed windows
• Unused chimneys
• Loft hatches
• Gaps around pipework
• Suspended timber floors

Appropriate draught proofing can help reduce unnecessary heat loss without preventing the controlled ventilation a property needs.

Review Loft and Roof Insulation

The roof area is an important part of a home’s thermal envelope. Where loft insulation is absent, damaged or compressed, improving it may help the property retain heat for longer.

A review should consider more than simply adding insulation.

• Existing insulation condition
• Loft ventilation
• Pipe and water-tank protection
• Loft hatch insulation
• Electrical cables and recessed lighting
• Signs of moisture or condensation

Investigate Wall Insulation Suitability

Walls can represent another important area of heat loss, but the correct solution depends on how the property was constructed.

Some homes have cavity walls that may be suitable for cavity insulation. Older buildings may have solid walls requiring a different approach.

• Wall construction
• Exposure to wind-driven rain
• Existing damp or defects
• Ventilation
• Thermal bridging
• Moisture movement
• Property appearance
• Planning considerations

Consider Floor Heat Loss

Ground-floor comfort can influence how warm occupants perceive the entire property to be.

Some Derby properties with suspended timber floors may experience cold air movement or heat loss through the floor.

Suspended timber, solid concrete and other floor constructions require different approaches. Ventilation beneath suspended floors should also be considered.

Improve Heating Controls

Once avoidable heat loss has been considered, review how the existing heating system is controlled.

A system can waste energy even where the main heating equipment remains serviceable.

• Heating schedules
• Thermostat settings
• Thermostatic radiator valves
• Heating zones
• Hot-water schedules
• Smart heating controls

Review Radiator and Heat Distribution Performance

A heating system may generate enough heat while distributing it poorly around the property.

• Some rooms warm while others remain cold
• Radiators take a long time to warm
• Cold areas within radiators
• Noise within the system
• Rooms regularly overheating
• Heating running for extended periods

Heat emitters should be considered as part of the overall heating design rather than as an afterthought.

Establish What the Property Actually Needs

Before making a major change to heating technology, it is important to understand how much heat the property actually requires.

This is one reason insulation improvements are often considered before final heating-system design.

• Property dimensions
• Building construction
• Existing insulation
• Windows and doors
• Air leakage
• Room-by-room requirements

Decide Whether the Existing Heating System Still Fits the Plan

Only after understanding the building and its heat demand should homeowners consider whether the main heating system remains appropriate.

• Current system age
• Reliability
• Energy source
• Property heat demand
• Radiator suitability
• Available space
• Electrical capacity
• Long-term renovation plans

Consider Low-Carbon Heating Where Appropriate

For suitable properties, a heat pump may form part of the longer-term home energy plan.

Heat pumps operate differently from conventional fossil-fuel heating systems and should be designed around the property’s heat requirement and suitable heat emitters.

Reducing excessive heat loss and understanding radiator requirements can help create better conditions for efficient lower-temperature heating.

Consider Solar PV as Part of the Wider Energy Plan

Heating improvements and solar electricity are different parts of a home’s energy system, but they can increasingly interact as homes become more electrified.

Solar PV can generate electricity for household use during daylight hours.

• Available roof area
• Roof orientation
• Shading
• Electricity consumption
• Potential system size
• Household occupancy patterns

Future electric heating, EV charging or battery storage should also be considered when planning longer-term electricity demand.

Check Whether Your Derby Home May Qualify for Energy Support

Before paying for major improvements, Derby households should check whether any current energy-efficiency support schemes apply to their property and circumstances.

Derby City Council provides home-energy guidance and information relating to available support routes.
