UK Electric Heating Industry Update: September 2026

If you’re tracking where the market is heading, this UK electric heating industry update for September 2026 covers the most important shifts across regulation, low-carbon heating deployment, renewables in new builds, and energy-bill policy.

From smart appliance rules being delayed to changes in VAT on electricity, September offered several signals about how the UK’s heating landscape is evolving — and what manufacturers, installers, and homeowners may need to prepare for next.

Key takeaways from this UK electric heating industry update: 

• Smart electric heating appliance requirements are now expected in late 2028

• Retrofit heat pump installations fell 22% in H1 2026

• New-build standards continue to push renewable electricity expectations

• The Boiler Upgrade Scheme evaluation highlights consumer experience and barriers

• Heat networks received £90m in new funding

• VAT removal from electricity bills could materially affect electric-only households

1) Smart electric heating regulations pushed back to 2028

The Government updated its Smart Secure Electricity Systems (SSES) programme in September, confirming a later implementation date for future requirements affecting electrical heating appliances.

The implementation date is now expected to be 31 October 2028, or two years after the regulations are made (whichever is later).

These regulations aim to ensure smart electrical appliances can support a more flexible electricity system, including expectations around:

Metering

Cybersecurity

Interoperability and smarter demand-side response (where applicable)

For the sector, this part of the UK electric heating industry update matters because it gives manufacturers and suppliers more time to prepare for a market where connected controls and smart heating management will likely become standard.

2) UK heat pump installations fall 22%

Government statistics published on 10 September reported that 20,895 retrofit heat pumps were installed in the first half of 2026 — a 22% decrease versus the same period in 2025.

Air-to-water heat pumps accounted for 99% of installations.

This is notable given the Government’s ambition to reach 450,000 heat pump installations per year by 2030. The figures reinforce that low-carbon heating adoption is still facing practical barriers — including cost, installer capacity, and suitability across the existing housing stock.

3) New-build rules increase the focus on renewable electricity

New Government guidance published on 8 September provided clarification on the 2026 edition of Approved Document L.

For new homes, the renewable electricity requirement uses an output equivalent to solar PV panels covering 40% of the dwelling’s ground-floor area under the specified calculation (subject to rules and site constraints).

This is another clear signal in this UK electric heating industry update: housing policy continues to move towards:

Greater electrification

Higher energy efficiency

More on-site renewable generation

As solar PV becomes more common, the relationship between renewable generation, smart controls, and electric heating will become increasingly important — especially for reducing running costs and improving grid flexibility.

4) Government publishes final Boiler Upgrade Scheme evaluation

On 24 September, the Department for Energy Security and Net Zero published its final 2026 evaluation of the Boiler Upgrade Scheme.

The evaluation explores homeowner experiences after installing low-carbon heating, including:

Energy bills and tariffs

Installer participation

Employment impacts

Value for money

Consumer support needs during the transition

This is useful context for anyone involved in low-carbon heating, because real-world consumer outcomes (not just targets) will influence future policy, funding, and public confidence.

5) £90 million announced for cleaner heat networks

The Government also announced £90 million of investment in new and upgraded heat networks during September, with more than 750,000 homes expected to benefit.

Projects include a major London heat network and an extension to a scheme in Bradford serving homes, schools, colleges and a hospital.

The key point here is diversity: the UK is exploring multiple routes to decarbonise heating — rather than relying on one solution for every property type.

Extra worth knowing: VAT is being removed from electricity bills

Although announced at the end of August, this is particularly relevant heading into winter.

From 1 October 2026 to 31 March 2027, VAT will be removed from domestic electricity bills, while gas will remain subject to 5% VAT.

Ofgem has said households that use proportionally more electricity could see a greater benefit — making this especially relevant for electric-only households and anyone assessing electric heating running costs.

This policy change is a meaningful addition to the September UK electric heating industry update, because it may influence consumer decision-making during the colder months.

What does September 2026 tell us about the direction of travel?

September’s developments show the UK’s transition to lower-carbon heating is progressing on several fronts — but not always at the pace policymakers want.

Smart appliance regulation is moving (just later), new-build standards are reinforcing renewables, and investment continues across heat pumps and heat networks. Meanwhile, energy-bill policy changes could shift the economics for electric-only homes in the near term.

We’ll be back next month with another UK electric heating industry update covering the biggest developments across electric heating, energy, and sustainability.
