Question 1

Do you provide ESOS Lead Assessor services in London?

Accepted Answer

Yes. Smart GreenTech Solutions provides ESOS Lead Assessor and Phase 4 compliance services across London and Greater London. As a London-based consultancy, we support organisations throughout the ESOS process, including energy data analysis, site audits, reporting and Lead Assessor review.

Question 2

Which London businesses need to comply with ESOS Phase 4?

Accepted Answer

ESOS applies to large UK undertakings and corporate groups that meet the relevant qualification criteria on the Phase 4 qualification date of 31 December 2026. Qualification is based primarily on employee numbers and financial thresholds, rather than the type of business or its location.If you are unsure whether your organisation qualifies, see our ESOS Phase 4 qualification thresholds and criteria guide.

Question 3

Do ESOS Phase 4 energy audits require site visits?

Accepted Answer

Yes. ESOS Phase 4 requires site visits as part of the energy audit process. The number and selection of sites will depend on factors such as your organisation's energy consumption, property portfolio and the activities undertaken at each location.We can help establish an appropriate audit programme for London sites and wider property portfolios.

Question 4

Can you manage ESOS for organisations with multiple London sites?

Accepted Answer

Yes. We have experience supporting organisations with complex and multi-site property portfolios. We can coordinate energy data collection and site audits across multiple London locations, working with facilities teams, building managers and other stakeholders to manage the process efficiently and minimise disruption.

Question 5

Can you manage ESOS if we have sites both inside and outside London?

Accepted Answer

Yes. Although we are based in London, Smart GreenTech Solutions provides ESOS compliance services throughout the UK. We can coordinate a single ESOS programme covering your London properties alongside sites elsewhere in the country.For further information, see our UK ESOS Phase 4 compliance service.

Question 6

How do you minimise disruption to occupants?

Accepted Answer

After we have identified how many buildings we need to inspect, we co-ordinate the audit and access to the relevant areas  with the building/facilities team to minimise any disruption. Where this is not possible we also offer an after-hours or weekend energy audit service.

Question 7

How much does an ESOS assessment cost in London?

Accepted Answer

The cost of ESOS compliance depends on the size and complexity of your organisation and the scope of the assessment. Factors include the number and type of sites, energy consumption, availability of energy data, the number of site audits required and the geographical spread of your portfolio.We can review your requirements and provide a proposal tailored to your organisation and Phase 4 compliance needs.
