Designed for Insulated Homes

Upgrade your home to low-carbon heating with a professionally designed air source heat pump system, installed as part of a fabric-first approach for maximum efficiency, comfort, and long-term savings.

At MAINCO, we don’t install heat pumps in poorly insulated homes.
We design systems that work properly, starting with heat-loss reduction.

Heat Pump Installation

WHY HEAT PUMPS WORK BEST WITH INSULATION

Heat pumps perform at their best in homes with low heat demand.

That’s why our heat pump installations are ideal for properties that already have — or are upgrading to — external wall insulation (EWI).

  • Lower heat loss = smaller heat pump required

  • Improved efficiency and performance (higher COP)

  • Reduced running costs

  • More even, comfortable heat

  • Strong EPC improvements

  • Future-ready, low-carbon home

Our Approach: Fabric First, Heating Second

We follow a whole-house mindset, not a one-size-fits-all installation.

Every system is designed around your property — not rushed or oversized.

  • Property assessment and heat-loss review

  • Insulation and fabric performance checks

  • Correct heat pump sizing (no oversizing)

  • System design tailored to your home

  • Professional installation and commissioning

  • Clear handover and system guidance

Grants & Energy-Efficient Upgrades

Heat pump installations may be eligible for government support schemes, depending on your property and upgrade pathway.

We can advise on:

  • Heat pump suitability

  • Upgrade sequencing (insulation first)

  • Long-term energy performance improvements

If you’re planning insulation, render, or wider energy upgrades, we’ll help you do it in the right order.
