Free, no obligation. We match you with vetted MCS-certified local installers.
Installs typically run £8,000–£14,000. With the £7,500 Boiler Upgrade Scheme grant (England & Wales), many homeowners pay roughly £5,000–£6,500 — and Scotland and Wales have their own schemes. Always get at least two MCS-certified quotes.
The Boiler Upgrade Scheme has no income limit in England & Wales — you mainly need a valid EPC with no outstanding insulation recommendations, and an MCS installer. Scotland (Home Energy Scotland) and Wales (Nest) have their own, partly income-based routes. Check the guide for your nation.
They work best in reasonably insulated homes. A good installer assesses your property first. Insulation grants can help you prepare — see the insulation page.
