Insulation Upgrades

Insulation: The Foundation Of Energy Savings

Better insulation = heat pump works smarter, your bills drop lower. Government grants available.

Without proper insulation, even the best heat pump has to work harder. Insulation is the foundation that makes everything else perform better.

Flowing Energy into the Future

Home Insulation

The Problem

A highly efficient heat pump is wasted in a poorly insulated home. It works harder and longer to maintain temperature.

Result: Lower savings, slower ROI, higher running costs.

The Solution

Proper insulation (internal walls, loft, pipes) lets your heat pump do its job efficiently.

Internal Wall Insulation (IWI)
Loft Insulation
Pipe Lagging
Government grants available

The Result

Savings: £200-600/year on heating

Efficiency: Heat pump works smarter

Cost: Often zero with grants

Internal Wall Insulation

Solid-wall properties lose up to 35% of their heat through uninsulated walls. Internal Wall Insulation (IWI) is the most effective upgrade for these homes — insulated boards fitted to the inside of external walls dramatically reduce heat loss, lower energy bills, and make your heat pump work smarter, not harder.

Insulation In Action

Internal Wall Insulation (IWI)

Insulated boards fitted to the inside of solid external walls. Our specialist service for solid-wall properties. Reduces heat loss by up to 35%.

Loft Insulation

Rolls of mineral wool laid across your loft floor. Quick to install with immediate impact on heat retention.

Pipe Lagging

Foam insulation wrapped around hot water pipes to prevent heat loss. Keeps water hotter and reduces heat pump workload.

Insulation Types & Grants

Internal Wall Insulation (IWI)

Our specialist insulation service for solid-wall properties

What It Is:

Insulated boards or panels fitted to the inside of solid external walls. Adds a thermal barrier without altering the exterior of your property.

Where It Works:
  • ✓ Solid-wall properties (pre-1920s, Victorian, Edwardian)
  • ✓ Homes without cavity walls
  • ✓ Properties built before cavity construction
  • ✓ Can be retrofitted room by room
Installation:
  • ✓ Fix insulated boards to internal wall surface
  • ✓ Plaster finish for a seamless look
  • ✓ Typically 1-2 weeks per room
  • ✓ Minimal external disruption
  • ✓ Professional installation by our team
Savings:
  • ✓ Annual energy saving: £200-400
  • ✓ Reduced heat loss by up to 35%
  • ✓ Improved comfort (warmer walls, fewer draughts)
Grant Coverage:
  • Boiler Upgrade Scheme: Can include
  • ECO4 Scheme: Full cost coverage

Loft Insulation

Why It Matters: Heat rises. A poorly insulated loft loses 25% of your home's heat.
What We Install:
  • ✓ Mineral wool rolls (most common)
  • ✓ Blown-in insulation (for difficult spaces)
  • ✓ Rigid boards (for additional performance)
  • ✓ Typical depth: 200-300mm
Installation:
  • ✓ Access via loft hatch
  • ✓ Lay insulation between joists
  • ✓ Seal gaps around pipes/wires
  • ✓ Takes 1 day
  • ✓ Clean process
Savings:
  • ✓ Annual energy saving: £400-600
  • ✓ 25% heat loss reduction
  • ✓ Improved summer comfort (keeps cool air in)
Grant Coverage:
  • Boiler Upgrade Scheme: Can include
  • ECO4 Scheme: Full cost coverage

Pipe Lagging

What It Is:

Foam insulation wrapped around hot water pipes to prevent heat loss.

Why It Matters:

Hot water loses heat as it travels through pipes. Lagging keeps water hotter, reduces heat pump workload, saves energy.

Installation:
  • ✓ Simple wrap-around application
  • ✓ Takes few hours
  • ✓ Can DIY but we offer professional fitting
Savings:
  • ✓ Annual energy saving: £100-200
  • ✓ Improves system efficiency by 5-10%
  • ✓ Often included free with heat pump installs
Bonus:

Often included FREE with heat pump installations

Heat Pump + Internal Wall Insulation (IWI)
  • Estimated savings: £500-700/year
  • ROI: 8-10 years
  • Payback improved by 20%
Heat Pump + IWI + Loft Insulation
  • Estimated savings: £700-1,000/year
  • ROI: 6-8 years
  • Heat pump working at peak efficiency
Heat Pump + All Insulation + Solar
  • Estimated savings: £1,200-1,800/year
  • Complete energy independence
  • Multiple grants leverage
