Top tips
Hiring a renewable energy, without the regret.
Four moves that separate a smooth job from a nightmare.
Use MCS-certified installers only.
BUS, ECO4, SEG payments all require MCS-certified installation. Any installer without MCS means no grants and no SEG export tariff.
Get a heat-loss survey for heat pumps.
Heat pumps must be properly sized to your house heat loss. Insist on a Heat Loss Calculation (MCS-recognised) — never a 'kW per m²' shortcut.
Check radiator compatibility.
Heat pumps run at lower flow temps (35–55°C vs 70°C for gas). Most existing rads are undersized. Cost: £200–£500 per upgraded rad — get this on the quote.
Don't oversize solar PV.
Generation beyond what you export earns 5–15p/kWh (SEG). Generation you use saves 30p+. Right-sized to consumption beats massive arrays for ROI.
