Are Heat Pumps Worth It? A Plain Answer for Walsall Homeowners

Q: Are heat pumps worth it for an older house?

Often they can be, but it depends on the home. Older properties may need larger radiators or extra insulation to heat comfortably. We check this at the free survey and put anything extra in the written quote, so you know the full picture before agreeing to anything.

Q: Can I get the grant if I rent my property out?

The scheme requires you to own the property and replace a fossil fuel system (GOV.UK, 2026). Most new builds and social housing are excluded. Check GOV.UK for the official position on your situation, and we’ll refer you to our MCS-certified partner if you qualify.

Q: Will a heat pump make my bills drop?

Not always. A heat pump can cost slightly more to run than a new gas or oil boiler on standard tariffs, but a time-of-use tariff can bring costs below a gas boiler (Energy Saving Trust, 2026). Your tariff and current system both matter.

If you’re wondering whether heat pumps are worth it, you’re not alone, and you deserve a straight answer rather than a sales pitch. Eco Air Source Heat Pump Installer is based in Walsall, WS1, and open 7 days, 9am–7pm. This guide covers what a heat pump costs, what it costs to run, and which homes suit one best. If you’d rather talk it through, call 01922 302461 and we’ll answer plainly. A free home survey is available too.

What does it cost to install one?

Installation prices vary a lot between guides, because every home is different. The Energy Saving Trust puts the typical UK cost at around £12,000 (Energy Saving Trust, 2026). Other sources give wider ranges:

Checkatrade quotes £3,000 to £15,000 on average, not including extras such as upgrading radiators (Checkatrade cost guide, 2026).
Heatable suggests around £7,000 to £13,000, depending on property size, system design and upgrades (Heatable, 2026).
Worcester Bosch gives £5,000 to £15,000 (Worcester Bosch, seen Oct 2026).

The spread is wide, so treat any figure as a starting point. The only number that matters is the one written on a quote for your house. Our free survey ends with a written quote, so you can see exactly what is and isn’t included before you decide.

Will it save you money to run?

This is where honesty matters. Heat pumps are more than three times more efficient than a gas or oil boiler (Energy Saving Trust, 2026). However, on standard tariffs electricity is nearly four times more expensive than gas, so a heat pump can cost slightly more to run than a new gas or oil boiler (Energy Saving Trust, 2026).

That doesn’t make it a bad idea. The same source notes that a heat pump time-of-use tariff can bring running costs below a gas boiler. So your choice of tariff matters, and it’s worth looking at before you commit.

If you’re replacing electric heating or LPG, the comparison often looks different from a modern gas boiler. We’ll talk through your current setup during the survey rather than guess.

Which homes suit a heat pump best?

A heat pump works best in a home that holds heat reasonably well and has space for the equipment. Some practical points:

Hot water cylinder: one can usually fit in any cupboard that measures at least 80cm x 80cm (Energy Saving Trust, 2026).
Outdoor unit: a monobloc keeps all components in one outdoor unit and is cheaper and quicker to install, while split systems can be slightly more efficient (Energy Saving Trust, 2026).
Planning: most installations are permitted development, so no planning permission is needed, but check with your local planning department if you live in a listed building or conservation area (Energy Saving Trust, 2026).
Radiators: some homes need larger ones to heat rooms well at lower water temperatures. We’ll check this at the survey, as it affects the quote.

If you’re moving off mains gas, our Gas Boiler to Heat Pump Replacement page explains how the process works from survey to commissioning.

How does the £7,500 grant change the sums?

Homes in England and Wales can get £7,500 towards an air source heat pump through the Boiler Upgrade Scheme (Energy Saving Trust, 2026). You must own the property and be replacing a fossil fuel heating system such as oil, gas, electric or LPG (GOV.UK, 2026).

We are not MCS certified, so the grant comes through our MCS-certified partner, who quotes, installs and applies for it on your behalf. GOV.UK says the grant value is taken off what you pay for installation and shown on your quotation and invoice (GOV.UK, 2026). If you don’t need the grant, we install the heat pump ourselves.
