Source board checked 2 October 2026
Use this board to find the current primary source for a decision, then keep the relevant evidence with the affected quote or job. It separates laws, industry standards and tax administration. A date for one jurisdiction or type of work does not change every UK job.
Sources checked 2 October 2026. Check the linked source when planning affected work and record any changed requirement with the responsible person.
1 October: IGEM/UP/1B Edition 4 is in effect
UK gas industry standard — in effect. IGEM says Edition 4 took effect on 1 October 2026 and Edition 3 was withdrawn on 30 September. The standard concerns tightness testing and direct purging of small installations within its stated scope.
Action: the appropriately registered, competent gas worker needs the current licensed standard for affected work. Keep the applicable work record and any supporting documents with the job. The boiler-service record page explains the record boundary; its PDF is a service record, not a replacement for the standard or a redesigned test certificate.
5 October: first 2025/26 Self Assessment notification
UK tax administration — approaching. Someone who needs to report self-employment for 2025/26 for the first time generally needs to tell HMRC by 5 October 2026. Whether a return is required depends on the actual income and circumstances; receipt of a notice to file also matters.
Action: use the UTR and first-year calendar to check registration. Filing and payment dates are separate. After 5 October, follow HMRC’s current route rather than treating this dated entry as a countdown or waiting another year.

15 October: BS 7671 Amendment 4 changeover
UK electrical installation standard — transition ending. BS 7671:2018+A4:2026 was published on 15 April 2026. The IET says the previous Amendment 3 edition remains valid until 15 October 2026. This is a standards change, distinct from legislation and England’s building-notification rules.
Action: review the edition relevant to the proposed work with the competent person, have the current licensed standard available and retain the edition used in the work’s paperwork. An older installation is not unsafe solely because its standard has been superseded. Use the electrical dates and records guide and the appropriate EIC or EICR record.
21 October: England cross-pavement EV planning change
England planning law — enacted, not yet commenced. SI 2026/1056 was made on 25 September and starts on 21 October 2026. It changes specified planning rights for chargepoints and authorised pavement-embedded cable channels. The order’s conditions and highway-authority authorisation remain separate checks.
Action: record parking, property permissions, the proposed route and the actual authority response before promising work. The EV planning guide separates planning from installation and electricity VAT. Use the EV survey questions to identify evidence needed for the quote.

7 November: cumulative MTD Income Tax update
UK tax administration — approaching for people already required to use MTD. The next 2026/27 quarterly-update deadline is 7 November 2026. Updates are cumulative income/expense summaries, not quarterly tax returns or new payment dates.
Action: use the MTD cohort and readiness sheet to check the comparison income year, exemptions, records and reporting software. Use HMRC’s recognised-software finder to choose the filing service; keep the supporting quote and job paperwork with your own business records.
