How to compare gas and air source heat pump quotes in Alresford and Itchen Valley
The fair comparison is the full scope of each option, including upgrade work and the assumptions behind any running-cost estimate.
Gas quote scope
Boiler, flue, controls, labour, warranty and disposal should be clear.
Air source heat pump scope
Outdoor unit, cylinder, radiators, controls, electrics and commissioning should be itemised.
Grant line
Any approved GBP 7,500 grant should be shown separately from the full installed price.
When a gas to air source heat pump switch needs caution
Some gas-heated homes need extra design work before the air source heat pump case is strong.
Low short-term budget
A like-for-like gas boiler may still have the lower initial cost.
High heat loss
Poor insulation can increase system size and radiator upgrades.
Cylinder space
Homes without a suitable hot water cylinder need a practical storage plan.
What to ask before switching from gas to an air source heat pump
Before choosing, ask installers to explain what happens to the existing gas system and controls.
Old boiler and flue
Removal, disposal and any wall repairs should be covered or excluded clearly.
Controls change
Ask how heating schedules and room temperatures will work day to day.
Electrical work
The quote should include isolator, wiring and consumer-unit requirements where needed.

Common questions
Can I get quotes to replace a gas boiler in Alresford and Itchen Valley?
Yes. You can compare MCS installer quotes for replacing a gas boiler in Alresford and Itchen Valley, but the useful price should be based on a home survey rather than a like-for-like appliance estimate.
Will the Boiler Upgrade Scheme apply when replacing a gas boiler?
It may apply if the home, existing heating and air source heat pump installation meet the scheme rules. The installer confirms eligibility and should show any approved GBP 7,500 grant separately.
Is replacing a gas boiler usually cheaper than fitting an air source heat pump?
A simple gas boiler swap is usually cheaper upfront. The air source heat pump quote needs to show grant treatment, radiator changes, cylinder work and running-cost assumptions before the comparison is fair.
Do I need to remove my gas supply?
Usually no. Many homes keep the gas supply for other appliances or future flexibility, but the installer should explain what happens to the old boiler, flue and controls.
What gas bill information helps the quote?
Annual gas kWh, boiler age, hot water setup and rooms that feel cold help installers compare the existing system with the proposed air source heat pump.
