Renovating in 2026? Why a heat pump should be on your checklist

If you’re renovating in 2026, it’s worth thinking about your heating earlier than you might expect. A heat pump, planned alongside insulation and layout changes, can be far easier to install during a renovation than adding one later as a standalone upgrade, especially when planned in with an energy provider like E.ON Next who offer an end-to-end service that simplifies the whole heat pump installation process.

Why should heating be part of your renovation planning?

Renovating is when you have the best chance to improve efficiency with the least disruption. If you’re already lifting floors, opening walls or improving insulation, it makes sense to look beyond a straight boiler replacement.

Heat pumps work best in well‑insulated homes, and renovation is the ideal time to upgrade. According to the Energy Saving Trust, heat pumps perform most efficiently when paired with good insulation and modern heating controls, which is why planning them as part of a wider renovation almost always delivers better results than fitting them in later.

For example, a homeowner extending their home can upgrade insulation levels, replace radiators where needed and size a heat pump correctly in one go - rather than trying to adapt an older system after the work is finished.

When is the best time of year to install a heat pump?

It is best to install a heat pump during a renovation in the warmer months because this allows time for all the paperwork and surveys to take place so the heat pump is in place for when you needthe grant and handle the paperwork on your behalf.

While the physical installation of an air source heat pump usually takes just a few days, the overall process starts much earlier. Home surveys, heat‑loss calculations, system design and Boiler Upgrade Scheme paperwork are all completed before installation day.

For example, E.ON Next’s end-to-end heat pump installation process can take around 6 weeks. Starting in spring or summer helps ensure everything is in place well ahead of colder weather, rather than rushing decisions when heating becomes urgent. Homeowners who leave heating upgrades until autumn often face delays and may end up relying on ageing boilers for another winter.

What financial support is available in 2026?

Many homeowners in England and Wales can still access significant upfront support from government grants.

The Boiler Upgrade Scheme offers grants of up to £7,500 towards the cost of installing an air source heat pump, helping to offset the higher upfront price compared to a boiler. The scheme runs until at least the end of 2027, and the installer, such as E.ON Next will apply for

This support is one reason renovation is such a good time to act. You’re already investing in the property, so it makes sense to use an available grant to upgrade your heating system, and in doing so significantly improve the long‑term value and running costs of your home.

Homeowners in Scotland can access alternative funding through the Home Energy Scotland Grant and Loan, which offers up to £15,000 (£7,500 grant + £7,500 loan) for heat pumps and energy efficiency.

How do smart tariffs make heat pumps more cost‑effective?

One of the advantages of a heat pump is how well it works with smart electricity tariffs. Because new systems are sold “smart‑ready”, they can be set to run at times when electricity is cheaper, rather than drawing power during peak hours.

The government backed this up in a 2025 statement which highlighted the fact that smart appliances, including heat pumps, could reduce running costs by shifting energy use away from peak periods.

For anyone planning a renovation with the future in mind, this adds up. A heat pump isn’t just about heating your home today - it’s designed to work as part of a smarter energy setup that can evolve as tariffs, technology and household habits change.

Why does end‑to‑end project coordination matter during renovation?

Because a heat pump isn’t a like‑for‑like swap - it’s a designed system, installing a heat pump involves assessment, design, paperwork and commissioning, not just fitting a unit. When this is coordinated as part of a renovation, everything works better: insulation levels are considered, radiators are sized correctly, and controls are set up to maximise efficiency.

Providers such as E.ON Next position heat pumps as a planned renovation upgrade rather than a bolt‑on, offering tailored home assessments and managing the process end‑to‑end so efficiency is built in from day one.

Will a heat pump make my home more appealing in future?

The government does not say that installing a heat pump will increase a property’s sale price. However, it is actively supporting a move towards low‑carbon heating through schemes such as the Boiler Upgrade Scheme, which offers grants to help households replace gas boilers with heat pumps.

This signals a long‑term shift in how homes in the UK are expected to be heated. As a result, homes that already use low‑carbon heating may feel better aligned with future government policy and heating standards, even if this does not directly translate into a higher resale value.

Will installing an air source heat pump improve my EPC rating?

Energy Performance Certificate (EPC) scores depend on insulation, system design and how the assessment is calculated. This is where confusion often creeps in. Heat pumps are highly efficient and low‑carbon, but EPCs are based on a modelled assessment of energy costs rather than real‑world performance. In some cases (particularly in poorly insulated homes or where older EPC methodologies are used) a heat pump on its own may not dramatically improve the score.

The Energy Saving Trust explains that EPC outcomes are at their strongest when a heat pump is installed alongside fabric improvements such as loft or wall insulation, and when the system is properly specified for the home.

It’s also worth knowing that EPC reform is underway. A report published in January 2026 by the Department of Energy Security & Net Zero, announced that the government is consulting on new metrics designed to better reflect heating systems, fabric performance and smart technology - making well‑planned heat pump installations more accurately recognised in future certificates .

What this means is that a heat pump planned as part of a renovation, with insulation and controls considered together, is far more likely to deliver both genuine efficiency gains and a stronger EPC outcome in the future.

The bottom line

If you’re renovating in 2026, a heat pump is worth considering earlier - now, not later.Planned alongside insulation improvements and installed ahead of winter, it can improve comfort, support better energy performance and help future‑proof your home. Renovation is your best opportunity to do it properly, with minimal disruption and maximum long‑term benefit.
