About storage heater installation in Barnet
Storage heaters store thermal energy during off-peak electricity hours (typically overnight on Economy 7 or Economy 10 tariffs) and release it gradually during the day. Each heater requires a dedicated circuit or a correctly rated spur from a dedicated heating circuit, connected through an off-peak meter or time switch. The installation covers the electrical circuit from the consumer unit, the off-peak switching arrangement, wall mounting of the heater, and commissioning. Modern storage heaters with fan-assisted output and electronic controls offer significantly better comfort and efficiency than older static models.
Storage heaters draw significant current — a single 2.55kW heater draws over 11 amps, and a typical property may have 3-5 heaters totalling 8-15kW. The off-peak circuit must be correctly configured through a time switch or smart meter, with adequate cable sizing and MCB protection for the combined load. Incorrect installation can result in heaters running on peak-rate electricity (tripling your heating costs) or overloading circuits. A new heating circuit from the consumer unit is notifiable under Part P.

Regulations & standards
- Part P of the Building Regulations (Approved Document P): A new heating circuit from the consumer unit is notifiable electrical work. It must be carried out by an electrician registered with a competent person scheme, or inspected by Building Control.
- BS 7671:2018+A2:2022 (IET Wiring Regulations): Storage heater circuits must comply with the Wiring Regulations, including correct cable sizing for the load, appropriate MCB/RCBO protection, and the requirements for fixed heating appliances.
- Electricity Safety, Quality and Continuity Regulations 2002 (ESQCR): The DNO may need to be notified if the total connected load significantly increases the property's maximum demand. Properties adding multiple high-wattage storage heaters may require a main fuse upgrade.
Storage Heater Installation FAQs
How does a storage heater work?
Storage heaters contain clay or ceramic bricks that are heated by electrical elements during cheap off-peak hours (usually 11pm-7am on Economy 7). The stored heat is then released gradually during the day. The input control sets how much heat is stored; the output control (or fan, on modern models) controls how quickly it is released.
Do I need Economy 7 for storage heaters?
You need a dual-rate electricity tariff — Economy 7, Economy 10, or a smart tariff with off-peak periods. Without a cheaper off-peak rate, storage heaters charge at the standard electricity price, making them very expensive to run. Contact your energy supplier to check or switch your tariff.
What is the difference between static and fan-assisted storage heaters?
Static storage heaters release heat passively through convection — you have limited control over when heat is released. Fan-assisted (or dynamic) storage heaters have a fan that blows air over the hot bricks on demand, giving you much better control. Modern high-retention models keep most heat stored until you need it.
Are there grants available for storage heaters?
The ECO4 scheme provides government-funded energy efficiency improvements for low-income and fuel-poor households. This can include replacing old inefficient storage heaters with modern high-retention models. Check eligibility via your energy supplier or the Simple Energy Advice service (gov.uk).
How much does it cost to run storage heaters?
A single 2.55kW storage heater costs approximately £40-60 per month on an Economy 7 tariff (charging for 7 hours at the off-peak rate). A typical 3-bed house with 4 heaters costs £150-250 per month in winter. Costs vary significantly based on tariff rates, insulation quality, and heater efficiency.
