Storage heaters and the first-time central heating grant: what counts

By Maya Ellis 5 min read

Bottom line

Storage heaters don't automatically disqualify you from a first-time central heating measure. If your home has no wet pipework, shared boiler or other central system, it may fit ECO4 rules. Your energy supplier, scheme administrator or council must confirm eligibility before work starts.

Quick recap

  • Storage heaters may count as room heating rather than central heating when no shared system or wet pipework exists
  • ECO4 Flex lets participating councils assess households under their published local criteria
  • Benefit-holder and Flex routes need different evidence
  • A council referral should come before an installer survey where ECO4 Flex applies
  • A partial wet system or communal heating can change the result
  • Check the official ECO4 guidance, your council's statement of intent and the government EPC register

Check whether your heating counts as central heating

Storage heaters don't always mean you qualify. They may count as room heating if each unit heats its own room and no wet system serves the home.

Check for radiators, underfloor pipework, a shared boiler or communal heat network. A boiler serving one radiator, a partial wet system or a communal system can change the assessment.

Replacing storage heaters never guarantees first-time central heating status. The energy supplier or scheme administrator applies the current ECO4 rules to your property and evidence.

Check the ECO4 route before choosing a system

ECO4 can fund heating measures in homes with electric room heating where the property and proposed work meet the scheme rules. Storage heaters alone don't prove eligibility. Before you commit to anything, it is worth looking at heat pump for central heating.

A home with partial radiators may need a different measure or fail the first-time route. Flats with communal heating need separate checks because the flat may already have central heating.

Your EPC and the technical survey support the decision. The survey checks pipe routes, insulation, electrical capacity, outdoor space and the proposed heating design.

ECO4 Flex applies only through participating local authorities. Each council publishes a statement of intent, setting out its own routes and evidence requirements. We cover preparing for eco4 application in its own article.

Councils may assess low income, health effects from a cold home or qualifying in-fill areas. The exact tests vary, so ask for the current referral checklist before collecting documents.

Use this order: find the council statement, request its referral form, submit evidence, wait for the council's declaration, then arrange the technical survey. A council normally issues a decision within several weeks, but it sets its own service time.

Ask how long the declaration remains valid. Councils set the validity period and may require a fresh declaration if the installer misses it. Get the expiry date in writing. The other half of this decision is sizing issues for heat pump with mvhr.

Prepare acceptable evidence before applying

Ask the council for its written checklist before sending documents. Councils can set different formats, date limits and signing rules under their statement of intent.

Benefit-holder evidence can include an official benefit award letter, entitlement notice or online benefit statement showing your name, address, award and assessment period. Send the full document, not a cropped screenshot.

For Flex income checks, councils may accept payslips, pension statements, bank statements, tax documents, benefit notices or an official income assessment. The council decides which items count and how recent they must be. There is more on replacement for renewable heat incentive in a separate guide.

For health-related Flex routes, ask whether it accepts a letter from a GP, hospital clinician, occupational therapist or another registered professional. A medical letter should explain how cold affects the condition. The council decides who may sign it.

In-fill applications need the council's own declaration or referral evidence. Don't substitute a neighbour's installer email unless the council accepts it.

Use clear PDFs or readable scans. Some councils accept photographs of complete pages, while others require certified copies or secure uploads. Ask before sending sensitive information. People in this spot often ask about smart thermostat compatible with heat pump and immersion as well.

Many councils require recent evidence, often from the current assessment period or a stated number of months. There is no single national age limit for every Flex document. Get the limit and accepted file formats in writing.

Check what the scheme covers and who does the work

ECO4 funding depends on the approved measure, property assessment and supplier decision. It may cover eligible equipment, installation and required associated work. It won't automatically cover every improvement or any amount above the approved scope.

Ask for a written breakdown before signing. It should show the measure, work included, any customer contribution, warranty terms and payment schedule.

Work under ECO4 is typically carried out by installers registered under the scheme frameworks, such as TrustMark or PAS schemes. Confirm the registrations required with the supplier or scheme administrator. Don't rely on a cold caller's badge or claim.

A supplier or scheme administrator decides whether a contractor can work on the measure. Ask who funds the job and who handles complaints. Report pressure for unexplained upfront payments to Citizens Advice and the scheme administrator.

Choose the system after the technical survey

A wet system needs space for pipework, radiators, controls and the heat source. Gas, LPG or electricity supply conditions also affect the design.

If a wet system won't suit the property, ask about high heat retention storage heaters or an air source heat pump. The survey must confirm the design, insulation needs and electrical capacity.

A heat pump funded separately may qualify for a Boiler Upgrade Scheme grant. Check the current amount and eligibility conditions on the government page, “Apply for the Boiler Upgrade Scheme”. ECO4 and the Boiler Upgrade Scheme are separate routes.

Modern storage heaters need less pipework but still depend on electricity prices and tariff settings. Ask for running-cost assumptions rather than relying on sales claims.

What works
  • Storage heaters: little or no wet pipework needed
  • Heat pump: may qualify for the separate Boiler Upgrade Scheme
  • Both: more controllable than older storage heaters
What to watch
  • Storage heaters: running costs depend on electricity tariffs
  • Heat pump: needs suitable insulation, design and outdoor space
  • Wet system: may fail where pipe routes or heat-source requirements cannot be met

Submit the right documents in the right order

Pull up your EPC on the government register before contacting an installer. Use the official service, “Find an energy certificate”, on GOV.UK. Keep the report PDF or a clear printout.

Prepare your address, tenancy or ownership evidence, heating photographs, meter details and the council's evidence checklist. Send the requested files in the format the council accepts.

For a benefit-holder route, submit the award evidence to the supplier or scheme administrator. For Flex, submit the evidence to the council first. Don't book work on a verbal promise.

Wait for the council's declaration where Flex applies. Check its issue date, expiry date, property address and approved route. Then book the technical survey with the contractor named or accepted by the scheme.

Ask for the proposed system, customer contribution and EPC improvement plan in writing. The survey decides final suitability.

  1. Find your EPC through GOV.UK's “Find an energy certificate” service and save the report
  2. Photograph storage heaters, radiators, meters, consumer unit and any boiler or heat-network equipment
  3. Ask the supplier or scheme administrator for its current benefit-holder evidence list
  4. If using Flex, find the council's ECO4 statement of intent and request its checklist
  5. Submit complete PDFs or accepted scans, photos or originals as the council requires
  6. Wait for the council declaration and record its validity period before booking the survey
  7. Book the technical survey with the approved contractor
  8. Get the proposed system, funding scope and any contribution in writing before work starts
The verdict

Storage heaters don't automatically block a first-time central heating assessment. Eligibility depends on the existing system, property survey, ECO4 rules and the evidence route.

Quick questions

Will my storage heaters be removed when the new system goes in?

The approved design decides. A full replacement may remove them, while another design may retain some units. Ask the installer to list removal, disposal and electrical work in writing.

Does ECO4 Flex cost me anything to apply for through the council?

The council referral itself is normally free. Ask who pays for any survey, certificates or extra work before agreeing. Report unexplained upfront demands to Citizens Advice and the scheme administrator.

I'm a renter with storage heaters. Can I apply?

You can ask about eligibility, but written landlord consent is normally needed before survey or installation. Check the council and supplier requirements.

Can I choose an air source heat pump instead of a gas boiler under ECO4?

The approved measure depends on the property, ECO4 rules and supplier decision. Ask whether ECO4 or the separate Boiler Upgrade Scheme is the correct route. Check “Apply for the Boiler Upgrade Scheme” on GOV.UK for current conditions.

What if my council has no ECO4 statement of intent?

Ask the energy supplier or scheme administrator which local authorities accept Flex referrals for your address. Don't assume another council will accept your application.

The council statement of intent often controls the Flex route. Read it and get the evidence checklist before arranging an installer visit.
