Are your electricians NICEIC certified?+
Yes. All our electricians are fully NICEIC certified approved contractors. This is the UK's leading electrical certification body and guarantees all our work meets the highest safety standards.
How quickly can you respond to an emergency?+
Our average emergency response time across London is 60 minutes. We aim to reach you as quickly as possible — in many cases within 30-45 minutes depending on your location and traffic conditions.
How much does an EICR certificate cost?+
EICR pricing depends on the size of your property and the number of circuits. A typical 2-bed property starts from around £120-£150. Call us on 07450 630937 for a free, no-obligation quote specific to your property.
Is an EICR certificate a legal requirement?+
Yes — for rental properties in England, landlords are legally required to have a valid EICR carried out at least every 5 years. This became law in June 2020. Failure to comply can result in fines of up to £30,000.
How long does a consumer unit replacement take?+
A full consumer unit replacement typically takes 4-6 hours. We aim to complete most replacements in a single day. The power will need to be off for a portion of this time but we minimise disruption where possible.
Do you provide written quotes?+
Yes, we always provide a clear written quote before starting any work. There are no hidden charges — the price we quote is the price you pay, unless the scope of work changes.
Do you carry out commercial electrical work?+
Yes. We carry out commercial electrical work for offices, shops, restaurants, warehouses and industrial units across London and Hertfordshire. This includes new installations, PAT testing, maintenance contracts and emergency callouts.
Can I get an EV charger installed at home?+
Yes. We are OZEV approved EV charger installers. We install smart 7kW home EV chargers compatible with all major brands. Government grant funding may be available — call us to discuss your options.
Are your electricians DBS checked?+
Yes. All our electricians are DBS (Disclosure and Barring Service) checked. We are fully insured with public liability insurance on every job.
What certification do you provide?+
We provide all relevant certification for every job including EICR reports, Electrical Installation Certificates (EIC), Minor Works Certificates and Building Control notifications where required.
