Among the range are some stand-out features. For example, the Compress 5800i AW is known for its ultra-quiet operation and suitability for smaller homes, while the Compress 3400i AWS provides flexibility with both outdoor and wall-hung indoor units.

The range also features the Compress 7001i AW, ideal for new-builds and well-insulated homes. All Worcester Bosch heat pumps boast high-efficiency ratings of ‘A+++’ and utilise environmentally friendly R290 refrigerant.

Worcester Bosch heat pump prices

The cost of an air source heat pump from Worcester Bosch is between £6,505 and £10,200, including installation. These price estimates vary so widely because many factors can determine how much a heat pump will cost for your home's needs. 

For example, the heat pump's output size can increase its cost (the higher the output, the higher the cost). This is measured in kilowatts (kW), and in the Worcester Bosch range, 4kW models are suitable for smaller properties, while the larger 17kW models are designed for bigger homes or those with higher heating demands. 

In addition, you will need to consider the heat pump installation costs. These prices vary greatly depending on your property size, complexity of the installation, and individual installer rates. To give you a brief overview, we’ve listed some current market prices for Worcester Bosch heat pumps below.

Worcester Bosch heat pump installation costs
ModelPrice rangeInstallation costsTotal cost
Compress 5800i AW£3,720 - £4,670£2,785 - £4,540£6,505 - £9,210

Compress 7001i AW£1,720 - £5,660£2,785 - £4,540£4,505 - £10,200
Prices are estimates only.

In addition to the upfront installation costs, you should also account for annual maintenance, which can cost between £180- £300. This is an essential part of keeping your heat pump system running at optimum levels throughout the year. It may also be necessary to keep a warranty valid. 

Worcester Bosch offers a basic warranty cover of 2 years for their heat pumps, with options for extended cover in some circumstances. Additional cover can add to the overall costs, which is something to keep in mind.

Heat pump grants

It's worth noting that there are air source heat pump grants in the UK and schemes available to reduce the costs of installing a heat pump. These include:

Boiler Upgrade Scheme Icon
  • Boiler Upgrade Scheme (BUS)
    Under this government scheme, homeowners can receive £7,500 towards the costs of installing a heat pump. This can significantly reduce upfront costs and make heat pumps more accessible. You must meet certain criteria to be accepted for the grant, but more information can be found at the GOV.UK site.
  • 0% VAT
    Since 2022 the VAT rate for heat pumps has been reduced to zero. This means that households can benefit from lower upfront costs to install a heat pump. It’s estimated that you could save up to £2,450.
ECO4 Icon
  • Energy Company Obligation Scheme (ECO4)
    This scheme gives households living in fuel poverty or with low incomes access to free energy efficiency measures to improve their home heating. These measures can include installing low-carbon heating solutions, like a heat pump. Measures are provided directly by large energy suppliers or through local authorities. You find out more about applicant criteria at Ofgem.

Region-specific opportunities also exist with similar offers, such as the Home Energy Scotland Grant and Loan and Warmer Homes Scheme. Both can offer funding or loans to support home upgrades to reduce heating costs. 

To get a great deal on a Worcester Bosch heat pump for your home, it's recommended that you get quotes from multiple installers to compare offers. Qualified heat pump installers can assist you with grant applications and will recommend some of the best air source heat pumps in the UK to suit your needs.

Is a Worcester Bosch heat pump the right choice for my home?

Determining whether a Worcester Bosch heat pump is the right choice for your home depends on several factors. Firstly, you should assess the size of your home and your heating needs. Among its range, however, Worcester Bosch offers heat pumps suitable for various property sizes, from small apartments to large houses.

You should also consider if you want an air to water heat pump, or would like to install an air to air, or even a ground source heat pump. Unfortunately, Worcester Bosch only offers air to water models, but these can offer both heating and hot water (and are often more easily installed with existing central heating fixtures). 

The Worcester Bosch range is highly efficient and comes in just below other leading brands on cost. This means you can save on upfront costs and longer-term energy bills. With added benefits like Quite Mark accreditation for low noise levels and excellent brand reputation, this range could be ideal for your needs. 

To decide if a Worcester Bosch heat pump is right for your home, it's best to get a professional assessment. A qualified installer can evaluate your property's needs and provide a tailored quote. 

Finding a trusted, reliable installer can be a challenge. It can take hours of online searches and require filling in many forms. In some cases you’ll wait weeks for a response, leaving you frustrated and no further along in your heat pump journey.
