The Priority Services Register and ECO4 work: a UK household checklist (2026)

Guide by ApplyFreeBoiler.uk (Reliant Energy Solutions Ltd), a heating and insulation installer in Bury, Greater Manchester. We are not the government, Ofgem or an energy supplier.

The Priority Services Register is a free support service run by energy suppliers and network operators for households who may need extra help, for example during a power cut or planned supply interruption. If you or someone you live with is waiting for ECO4 heating or insulation work, it is worth checking you are on it. This checklist is general information from ApplyFreeBoiler.uk, a heating and insulation installer in Bury. It is not advice from your supplier, and it does not guarantee funding.

1. What the register is

Energy suppliers and the companies that run the local electricity and gas networks keep a Priority Services Register of customers who may need extra support. Joining is free, and the support offered can include advance notice of planned interruptions and help during power cuts.

2. Who it can help

It is aimed at households in vulnerable situations, which can include people of pensionable age, people with a disability or long-term health condition, households with young children, people who rely on medical equipment that needs power, and people who have difficulty communicating in English. Check with your supplier what applies to you.

3. How to join

Contact your energy supplier and ask to be added. You can also contact your local electricity network operator; the national power cut number 105 can help you find out who that is. You may need to sign up separately for gas and electricity if you have different suppliers.

4. Medical equipment and install day

If anyone at home relies on equipment that needs electricity, tell your installer before install day. Heating or electrical work can mean short interruptions, and the installer can plan around them.

5. Passwords and identity checks

Some suppliers can set up a password scheme so you can check that someone calling at your home is genuine. This can be useful when several visits are booked for a survey and installation.

6. Keep your details up to date

Tell your supplier if your circumstances change, or if you move home. Registers are not always carried over automatically when you switch supplier.

7. Other help with energy costs

Your supplier may also be able to talk to you about payment support if you are struggling with bills. Citizens Advice can give free independent advice on energy debt and support schemes.

8. Check funding and local figures

See ECO measures by council on ApplyFreeBoiler.uk, built from DESNZ Household Energy Efficiency statistics, to see how many ECO measures have been installed in your local authority area. Use the ApplyFreeBoiler.uk eligibility check to see whether an ECO4 heating or insulation pathway may be available for your home in England, Scotland or Wales. ECO4 is due to close on 31 December 2026.
