Technology planning, not a fixed-price offer

Planning a Whole-Home Energy Upgrade

A phased plan can coordinate solar, storage, charging and heating without assuming that every technology is appropriate for every home. Ben Hayden is the primary adviser for independent assessment and oversight; delivery remains with the relevant specialist.

What to specify

Electrical and solar

Assess supply and distribution-board capacity
Plan solar, batteries and EV charging with LIT
Compare demand reduction before extra equipment

Heating and cooling

Assess heat loss and seasonal occupancy
Plan heat pumps, air conditioning and controls with Agua-Therm
Check hot water and pool loads separately

Project coordination

Set the budget and order of works
Record responsibility for each interface
Agree commissioning and handover documents

Build the plan before comparing prices

Start with bills, comfort problems, occupancy and a property assessment.
Compare staged upgrades with an all-at-once programme, including disruption and financing costs.
Assign each scope to its responsible specialist and agree who coordinates decisions and aftercare.

This is a planning guide, not a documented customer installation. No customer quotes, measured savings, fixed package prices or verified returns are claimed.
