How much do Heat Recovery Systems Cost in the UK?

There are a number of site specific issues that need to be considered when trying to fix a price for any heat recovery installation. This can include the age of the property, the existing system and how difficult it is to access pipework, as well as level of insulation and the extent of building/installation work required.

The price of heat recovery also varies from domestic to business installations, as you would expect. In general terms, a domestic heat recovery and ventilation system could cost between £3,000 and £10,000 depending on the amount of work needed – the fixing of pipework, for example – and the size of the premises.

In commercial or industrial contexts, costs tend to be higher due to the complexity of systems and larger scale. Depending on the specific needs of the facility, costs for heat recovery systems in such settings could range from tens of thousands to several hundred thousand pounds.

A major hotel chain spent nearly £500,000 on a retro-fit of one of their large buildings, but for an average sized business you are looking at an investment of around £10,000 to £20,000. 

For business premises, the price of heat recovery is more difficult to assess, particularly because of the differing sizes and ages of the buildings. The cost of the ventilation unit is one aspect but the installation process is generally complex and often more invasive than other renewable technologies, with pipe work extending to all offices in the building.

A small office environment may well have comparable costs to domestic properties but larger concerns are certainly going to be pricier (and possibly offer a greater return on investment). 

It's worth noting that while the initial investment might seem significant, heat recovery systems can lead to substantial long-term savings on energy bills. Additionally, while there are currently no direct UK-wide grants specifically for MVHR systems, heat recovery may be installed as part of broader energy efficiency upgrades that qualify for schemes such as ECO4 or local authority funding, which can help offset installation costs.

There is also a number of site-specific factors that will impact upon the cost of installing a heat recovery system. These include:

• the complexities of the existing ventilation system
• boiler type
• access to pipework and duct routes
• the extent of building or renovation work required

Despite the variables involved, it is possible to give a rough idea of how much you can expect to pay. For a domestic MVHR system you can expect to pay around £2,000–£4,000 for simpler new build installations (retrofit projects often cost more), though this figure may well be higher for retrofit projects given potential installation difficulties. This price will usually include all parts (the heat exchanger, ducting, control panel, etc), installation, as well as the designing of the system to fit your property (though some companies may charge extra for this).

It is possible to install a heat recovery system yourself if you are competent at DIY, but achieving optimum efficiency, correct airflow balancing and compliance with Building Regulations generally requires a specialist installer. It is more difficult to calculate the cost of installing a heat recovery and ventilation system in commercial or office buildings as these can vary greatly in scale. Nonetheless, a system fitted in an average-sized office building may cost between £7,000 and £12,000.

The more efficient rotary heat exchanger variety of system will cost slightly more than this. Once again, individual factors will impact upon the installation cost, and retrofitting will almost always be more expensive. A boiler flue economiser for larger heating systems may cost between £6,000 and £8,000.

Savings when using Heat Recovery and Ventilation Systems

Heat recovery systems can help reduce your carbon footprint whether in a domestic situation or for business premises. We have already mentioned that any efficiencies stated by manufacturers or installers should necessarily be treated with caution because of the variables involved, particularly in older buildings where there will be issues such as the quality of insulation. Having said that, you can get a general idea of how a particular system is going to break even on the initial investment.

It is necessary to be cautious towards manufacturers’ claims about the energy saving potential of their products. That said, the break-even periods offered by heat recovery systems are often more predictable than those associated with other renewable heat technologies, such as heat pumps and solar thermal, particularly in commercial settings where heat demand is consistent.

According to more recent Carbon Trust guidance on heating, ventilation and air conditioning (HVAC), well-designed heat recovery systems can significantly reduce space-heating demand and overall energy consumption when integrated into efficient building services.

The Carbon Trust estimate that a commercial/office heat exchanger system with an efficiency of around 70% could save up to 30–40% from a company’s or organisation’s gas bill, depending on usage patterns and system design. High-efficiency rotary heat exchangers can deliver faster payback in suitable large-scale applications, though a complete return on investment within two years will depend on operating hours, fuel costs, and integration with existing systems. In the case of boiler flue economisers, the energy bill savings mean that you could break even after around four or five years. One should also recall the potential for improving the lifespan of the boiler due to reduced thermal shock.

Those who install a MVHR system in a domestic property may save around 15–30% on energy bills due to the reduced heating demand, and these savings could pay back the initial investment within 6 to 10 years, depending on individual factors such as the general energy efficiency of the house (insulation, air tightness, etc.), as well as the installation quality and quality of components used.

One should also note that heat recovery and ventilation systems are powered by electricity, so they will cost a small amount to run (the running costs per year including maintenance is approx. £130–£250 per year for typical domestic MVHR systems, depending on filter replacement frequency and electricity tariffs). Given the fact that energy prices have risen significantly in recent years and remain volatile, the savings offered by heat recovery systems can improve over time, particularly where systems are well designed and properly maintained.

For domestic properties, the price of heat recovery could produce that return in around 6 to 10 years (assuming a reduction in energy bills of 15 to 30%).

The Rising Cost of Energy and Heat Recovery

The benefits of installing a heat recovery system stems from the fact that energy prices have risen significantly in recent years and remain volatile, and we all need to make the best of the power that we use. In many cases, the price of heat recovery will be off-set by savings in efficiency and, if the price of gas and electricity continues to increase over the long term, this should improve dramatically over the next few years.

Case Study – Cascades Leisure Centre

The Cascades Leisure Centre in Portadown was built in the 1960s and was retrofitted with a heat recovery system at an overall cost of around £200,000, including installation. The savings on energy bills for the first year were estimated to be £40,000 which would see a return on investment in a little over five years. Find out more about the installation here.

Boiler Flue Economisers

Fitting a flue economiser on your boiler can reduce wastage by 5 and 15% in some cases. A system can cost between £6-8,000 for an industrial level boiler but can produce a return on investment within 5 to 6 years.

Heat Pumps

The costs of heat pumps vary between £7,000 and £25,000 depending on the type and installation requirements and can reduce heating-related energy consumption by up to 50% or more in well-insulated properties. Heat pumps are also eligible for the Boiler Upgrade Scheme (BUS).

The Future of Heat Recovery

There’s no doubt that with the renewables revolution we have come to understand that countering the ways we waste energy is almost as important as developing renewable technologies. The price of heat recovery is largely off-set by the long term savings on energy bills for many of our buildings, from our homes and offices, through to large industrial complexes that produce, and lose, tremendous amounts of heat.

Find the Heat Recovery Installer

As you will now be aware, the price of heat recovery can vary depending on a wide range of factors, including the age of your property, what you use it for, and the level of installation required.
