For guidance only. The responsibility for any electrical installation lies with the qualified person carrying out the work. Always verify calculations independently and apply professional judgement.
The Three VAT Rates for Electricians
UK electricians need to apply the correct VAT rate depending on the type of work and property.
VAT rates by work type
HMRC VAT Notices 700, 708, 708/6| Rate | Scenario | Key Requirements |
|---|---|---|
| 0% | New-build residential construction | Must be a brand-new dwelling, not a conversion or extension |
| 0% | ESM — Solar PV installation | Residential property, supply and install together |
| 0% | ESM — Battery storage | Residential property, until 31 March 2027 |
| 0% | ESM — Heat pump installation | Residential property, qualifying energy-saving material |
| 5% | Renovation (property empty 2+ years) | Evidence that property has been unoccupied for 2+ years |
| 5% | Residential conversion | Converting non-residential building to residential use |
| 20% | Standard domestic work | Rewires, additional circuits, consumer unit upgrades |
| 20% | Commercial electrical work | All commercial and industrial electrical installations |
| 20% | Repairs and maintenance | Fault-finding, repairs, and general maintenance |
| 20% | EV charger (existing property) | Retro-fit EV charger to an existing dwelling |
Blocked items (appliances, alarms) are always charged at 20% regardless of project rate.
Energy Saving Materials (ESM) Zero Rating
Since April 2022, qualifying energy-saving materials installed in residential properties attract a 0% VAT rate.
The government reintroduced the zero rate for energy-saving materials to encourage homeowners to invest in renewable energy and energy efficiency. For electricians, the key qualifying installations are solar PV panels, battery storage systems, and heat pumps.
The zero rate applies to both the materials and the labour when supplied together as a single supply of installed goods. If you supply labour only (the customer provides the panels or battery), the labour element alone does not qualify for zero rating — it must be a combined supply and install.
ESM Deadline
To qualify, the installation must be in a residential property (or a building used for a relevant residential purpose such as a care home). Commercial installations do not qualify for the ESM zero rate.
Blocked Items
Always 20% VAT
- White goods (ovens, hobs, cookers, washing machines)
- Electrical appliances (TVs, fridges, freezers)
- Burglar alarm and security systems
- Fire alarm and detection systems
- Air conditioning and mechanical ventilation units
- Fitted furniture and built-in appliances
When preparing an invoice for a zero-rated or reduced-rate project, you must separate blocked items from qualifying materials. Show the blocked items on a separate line with 20% VAT applied. Failure to do so can result in HMRC assessments and penalties.
CIS Reverse Charge
The domestic reverse charge for construction services changes who accounts for VAT to HMRC.
Under the Construction Industry Scheme (CIS) domestic reverse charge, the customer accounts for the output VAT on their VAT return instead of the supplier. This applies when both parties are VAT-registered and the services are reported under CIS.
As an electrician subcontracting to a main contractor, you would issue an invoice showing the VAT amount but not adding it to the total payable. The main contractor then accounts for both input and output VAT on their return, making the transaction VAT-neutral for them.
When Reverse Charge Does Not Apply
Your invoice must include the statement: "Reverse charge: Customer to pay the VAT to HMRC." You should also show your CIS registration status and the applicable VAT rate.
