Why Manchester pricing is stable
Greater Manchester's mix of 3-bed semis and modern-insulation new-builds is well-matched to the Cosy 9kW. Where costs rise it's typically for older solid-wall terraces needing a larger unit and cylinder upgrade — flagged clearly at survey stage, not after the deposit.

Frequently Asked Questions
How much does an Octopus Cosy heat pump cost in Manchester?
A typical fully-installed Cosy heat pump in Greater Manchester costs £10,500–£14,500 before the Boiler Upgrade Scheme grant. After the £7,500 BUS grant (or £9,000 for oil/LPG replacement), most Manchester homeowners pay £3,000–£7,000 net.
What's included in the Cosy install price?
MCS heat loss survey, Cosy unit (6, 9 or 15.5kW), outdoor mounting, hot water cylinder if required, pipework and cabling, controls and Cosy Pod set-up, MCS commissioning, BUS grant paperwork, and Cosy Octopus tariff hand-off.
Does the Boiler Upgrade Scheme reduce the price at invoice?
Yes. As your MCS installer, Greentech deducts the £7,500 (or £9,000) grant directly from your invoice — you never pay the full amount upfront and reclaim.
Is Manchester more expensive than the UK average for Cosy installs?
No. Manchester is broadly in line with the national average. Older solid-wall terraces can push toward the top of the range because they need larger units and sometimes a hot water cylinder upgrade.
Can I finance the net cost after the BUS grant?
Yes — most Manchester customers use our 0% finance option or a lender-backed renewables finance plan. See our /finance page for current rates.
How long is the Cosy heat pump warranty?
The Cosy range carries a 5-year manufacturer warranty as standard, with an extended warranty option available. Greentech provides its own 2-year workmanship warranty on all installation work.
