Book assessmentBoiler replacement, lower bills, landlord planning, or a solar-first route.
Heat loss, roof potential, current setup, and likely grant fit are handled together.
The discount lands on the invoice instead of becoming another admin task for you.
Heat pump, solar, battery, or the combined route, with a clear finish to the job.
Who we work with
Make the switch before the old system forces your hand.
Use property-by-property planning, practical sequencing, and a clearer view of how the grant can support the route.
Off-gas properties are often where the heat-pump case becomes easier to justify both practically and financially.
Particularly relevant for EV owners, work-from-home households, and homes preparing for all-electric heating.
Live running cost comparison
Every heating system delivers heat at a different cost per kWh. This table shows the effective cost of heat — accounting for system efficiency and seasonal performance — so you can compare like for like.

Fuel prices are updated automatically. Performance figures are based on typical system assumptions. Actual running costs depend on property insulation, system design, tariff and usage. Gas and electricity prices reflect the Ofgem price cap for England and Wales (Direct Debit customers — prepayment rates are slightly higher). LPG shown is Calor 5kg propane refill price — bulk tank rates are typically lower.
Solar panels and battery storage
Turn more of your own generation into usable power instead of exporting it cheaply and buying it back later.
Solar alone for a typical home with steady daytime usage.
Solar plus battery where more of that generation is used at home.
Estimates are illustrative. Actual outcomes vary based on property size, insulation, usage, system design, and energy tariffs.
Every year you delay, you stay more exposed to grid electricity costs and miss the chance to use more of your own generation on site.
Boiler Upgrade Scheme
The Boiler Upgrade Scheme is property-based, not means-tested, and available to eligible homeowners and landlords in England and Wales replacing fossil-fuel heating with a heat pump.
Estimates are illustrative. Actual outcomes vary based on property size, insulation, usage, system design, and energy tariffs.
Waiting could mean paying full price later. The scheme is open until 31 December 2027, but delay still carries a practical cost when boilers fail or install schedules tighten.
We design and manage the Boiler Upgrade Scheme route as part of your system.
