Heat Pump Replacement in Walsall with a free home survey, plain-English written quotes and lower running costs on a time-of-use tariff. Call for a quote.
Eco Air Source Heat Pump Installer is based in Walsall (WS1), and we are open 7 days, 9am to 7pm. If you are replacing an old gas, oil, LPG or electric system, or an air source unit that has stopped doing its job, call 01922 302461 and we will talk it through with no pressure. Every job starts with a free home survey, followed by a written quote you can read in your own time. You are also welcome to visit our Walsall premises and speak to us in person. This page explains what heat pump replacement involves, what it costs, and where the grant fits in.
Understanding the Work
A heat pump takes warmth from the outside air and uses it to heat your radiators, underfloor heating and hot water. The Energy Saving Trust says heat pumps are more than three times more efficient than a gas or oil boiler (Energy Saving Trust, 2026). That is why they can be worth the upfront outlay.
Replacement work usually falls into one of two situations:
- Swapping a fossil fuel system for a heat pump. The old boiler is disconnected and removed. An outdoor unit is fitted, along with a hot water cylinder and new controls, and the existing pipework is reconnected where it is suitable.
- Replacing an existing air source heat pump. This might be because the unit is failing, was poorly sized, or is too costly to keep repairing. We assess what can be kept, such as pipework and radiators, and what needs renewing.
There are two main system types. Monobloc units keep all components in one outdoor unit and are cheaper and quicker to install, while split systems can be slightly more efficient (Energy Saving Trust, 2026). We will tell you which suits your home, and why.
Who Usually Needs This
- Homeowners in Walsall, Bloxwich, Aldridge, Brownhills, Willenhall, Darlaston, Wednesbury and Great Barr with an ageing oil, LPG or electric heating system.
- Households with a gas boiler nearing the end of its life who want to plan the switch rather than wait for a breakdown.
- Landlords who want a heating system that is simpler to manage across tenancies.
- Owners of an older heat pump that keeps developing faults or no longer heats the house properly.
Step by Step
- Phone call. You tell us about your home and current heating. We answer honestly, including when a heat pump may not be the right fit.
- Free home survey. We look at your insulation, radiators, pipework, cylinder space and where an outdoor unit could sit.
- Written quote. You receive itemised costs on paper. If you want the grant, we refer you to our MCS-certified partner (see below).
- Installation. The old system is drained and removed, and the new unit, cylinder and controls are fitted. Hot water work follows Building Regulations Part G, which covers hot water safety, including unvented cylinders.
- Commissioning and handover. We test the system, set it up and show you how to use the controls.
- Aftercare. If anything seems off in the first few weeks, call us and we will come back.
What You Gain
Lower running costs, if you choose the right tariff. 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. A heat pump time-of-use tariff can bring running costs below a gas boiler (Energy Saving Trust, 2026). We will explain this in plain terms before you commit.
Steady comfort. Heat pumps run at a lower temperature for longer, which suits a well-insulated home. Rooms stay evenly warm rather than swinging between hot and cold.
A simpler setup for the future. You are no longer tied to oil deliveries, gas supply or ageing electric storage heaters.
Peace of mind. Work is documented, and you will know exactly what was fitted and why.
What Affects the Price
Published figures vary, so here are several sources side by side:
- Around £12,000 is the typical cost of installing an air source heat pump in the UK (Energy Saving Trust, 2026).
- £3,000 to £15,000 on average, not including extras such as upgrading radiators (Checkatrade cost guide, 2026).
- £5,000 to £15,000 to install (Worcester Bosch, seen Oct 2026).
The spread is wide because every house differs. The main factors are:
- Property size and how well it holds heat
- Whether your radiators and pipework are suitable or need upgrading
- Where the cylinder will go (a cylinder can usually fit in any cupboard measuring at least 80cm x 80cm, according to the Energy Saving Trust, 2026)
- Unit type and capacity
- Any electrical work
We cannot give a fixed price without seeing the property. The free survey takes in these points, and the written quote that follows sets out each cost. We give you a timeline with the quote because it depends on the home and the system chosen.
How the grant works
Homes in England and Wales can get £7,500 towards an air source heat pump through the Boiler Upgrade Scheme (Energy Saving Trust, 2026). To qualify, you must own the property and be replacing a fossil fuel system such as oil, gas, electric or LPG (GOV.UK, 2026). Most new builds, social housing and properties already given government funding for a heat pump cannot claim (GOV.UK, 2026).
We are not MCS certified ourselves. If you want the grant, it comes through our MCS-certified partner, who quotes, installs and applies for it on your behalf. The grant is taken off what you pay, and it appears on your quotation and invoice (GOV.UK, 2026). If you do not need the grant, we install the heat pump ourselves.
Talk to Us Before You Decide

Commissioning and handover
We test the system, set the controls and show you how to run it.
Frequently Asked Questions
Typical figures run from £3,000 to £15,000 depending on the source (Checkatrade, 2026), with the Energy Saving Trust giving around £12,000 as typical (2026). Radiator upgrades are usually extra. Your own price depends on the home, which is why we survey for free and put the figure in writing.
Possibly. You must own the property and be replacing a fossil fuel system such as oil, gas, electric or LPG (GOV.UK, 2026). The grant comes through our MCS-certified partner, who quotes, installs and applies for you. Replacing an existing heat pump generally will not qualify, as properties already given government funding for a heat pump are excluded (GOV.UK, 2026).
Usually not. Most heat pump installations are permitted development, so no planning permission is needed, but you should check with your local planning department if you live in a listed building or conservation area (Energy Saving Trust, 2026). We will flag anything that looks unusual at the survey.
Yes, in most cases. A heat pump heats water to store it, so a cylinder is normally part of the job. It can usually fit in any cupboard measuring at least 80cm x 80cm (Energy Saving Trust, 2026). Unvented cylinders must comply with Building Regulations Part G, and we check space and layout at the survey.
Not always. Heat pumps run at lower water temperatures, so some rooms may need larger radiators to stay warm, while others work as they are. We check each room during the survey and list any radiator changes separately in your written quote, so there are no surprises.
