Whole-house retrofit
A one-off product rarely fixes a cold, expensive home. We assess the whole house, plan the upgrades in the order that actually works, and manage the installs from start to finish.
One accountable team from the first visit to the final sign-off.
A whole-house assessment: fabric, heating, ventilation, moisture risk and occupancy. We measure rather than guess, and we are independent of any one product.
A prioritised, costed plan in the correct fabric-first order, phased to your budget, with the grants you qualify for and the savings you can expect at each step.
We coordinate accredited, insured installers, oversee the work against the plan and sign it off, so the measures perform as designed and any funding stays valid.
These are the upgrades a survey draws from. Which ones suit your home, and in what order, is exactly what the assessment tells you.
Top up to 270mm of mineral wool at ceiling level, or insulate at the rafters for a warm loft or room-in-roof. Warm air rises, so an uninsulated roof is where you lose it fastest.
Cavity walls are filled with mineral-wool or bonded bead. Solid walls are insulated internally (IWI) or externally (EWI) with a new render finish. The survey confirms which wall type you have.
ECO4 / GBIS grants may apply
Insulation is fitted beneath suspended timber floors, or laid over a solid floor during renovation. Often combined with sealing the perimeter gap where floor meets skirting.
A-rated double or triple glazing and insulated doors, plus draught-proofing to gaps, letterboxes and floorboards. Secondary glazing is used where windows are protected or listed.
Replace a gas or oil boiler with an air-source heat pump — sized to the improved fabric, with correctly-sized radiators and smart controls. Most efficient once insulation is in place.

Seal uncontrolled draughts, then add controlled ventilation — trickle vents, humidity-sensing extract fans, or whole-house MVHR. Essential whenever a home is made more airtight (PAS 2035).
Roof-mounted solar panels with an optional battery to generate and store low-carbon electricity — a natural pairing with a heat pump to cut running costs further.

Indicative figures for a typical older home, confirmed by your survey.
Insulate and seal the building fabric before you size the heating. Do it the other way round and you pay for a bigger heat pump than you need, and it never runs at its best.
Loft, walls and floor: cut the heat loss first.
Controlled fresh air so a tighter home stays healthy.
Size a heat pump to the improved, lower demand.
Solar and battery to cut running costs further.
One survey gives you the whole picture: the measures, the order, the grants and the savings. Then we manage the installs.
