Every upgrade
Which upgrade makes sense for your home?
Most homes we survey use three or four of these. Filter by what you're considering, or browse the lot. Each card tells you what it costs, what it saves, and who it's for.
Everything we install, in one place
- Most popular
Insulation
Mineral wool. Cavity beads. Multifoil. We fit every type — but we recommend multifoil on most homes we survey. The 20th-century materials leak heat, compact over time, and use formaldehyde binders. Multifoil doesn't.

See insulation Multifoil
More than 20 layers of reflective foil and foam, 40mm or 80mm thick depending on where it's going. It outperforms 200mm of mineral wool because it reflects radiant heat back into the room rather than just slowing it down. In the right wall it transforms the home. In the wrong wall it traps moisture. The U-value calculation comes before the install, every time.

For solid-walled homes that have no cavity to fill. Our EWI wraps the whole house in 80mm of multifoil — more than 20 layers of reflective foil and foam — and then a waterproof cladding panel on top. The cladding itself is 100% watertight and adds another layer of insulation; you pick the look from a range of finishes — render, timber, stone. Cuts heat loss by 60–80% in most homes.

Solar PV
Most installers spec the system to fill the available roof. We spec it to match what you actually use at home during daylight, and the export tariff you switch to on commissioning day matters more than the brand of panel. Survey first, panels second.

See solar pv Battery storage
A 5kWh to 15kWh lithium-iron-phosphate battery, fitted wherever it suits the house — most often in the garage, sometimes in a utility room or a loft. It charges from your solar during the day and runs the house in the evening, instead of you buying that same electricity back from the grid at peak prices. A six-thousand-cycle warranty, twelve to fifteen years of useful life.

Heat pumps
Every heat pump quote starts with a room-by-room heat-loss calculation — not a postcode lookup, not an EPC guess. We turn down about one job in three because the maths doesn't add up. The survey tells you which one you are.

Waterproof. Breathable. Twenty-five years of written cover. Painted onto your walls or your roof — or applied invisibly over original brickwork in our transparent finish — ProPERLA is the only single-coat upgrade we know of that drops your U-value, refreshes your kerb appeal, and stops driving rain saturating the fabric at the same time.
