Money guidanceThis is general information, not financial or tax advice. Rules change, so check GOV.UK or speak to a qualified adviser.

Official sources currently tell two parts of the story: government has announced Boiler Upgrade Scheme support for qualifying heat batteries, while the live GOV.UK “what you can get” page checked on 10 November 2026 does not list heat batteries among technologies open for application.

Status on 10 November 2026

The planned grant is £2,500, subject to the relevant product, design and installation standards and eligibility rules. Government material says the qualifying system is intended to provide space heating and hot water, not merely replace a domestic hot-water cylinder.

Do not treat an announcement, an installer reservation or “grant ready” marketing as an accepted application.

What we monitor

  • the live GOV.UK application technology list
  • Ofgem scheme guidance and application dates
  • product and installation standards coming into force
  • MCS certification routes
  • official VAT guidance naming eligible energy-saving materials

VAT needs its own check

Heat storage and electrical battery storage are not automatically the same category. Ask the supplier to state the VAT rate and official basis on the written quote.

How this page changes

We update the checked date and source record when an official application page, regulation or standard changes. We do not use installer advertising as proof that a route is open.

What homeowners should do

Check GOV.UK on the day of quotation and before paying a deposit. Ask the installer to identify the exact product certification and rule they intend to use.

Your next step

Save a dated copy of the official eligibility page with the quote. If the heat battery is absent, budget without the grant until the application route is visibly open.
