Statutory Compliance Calendar for Estates (UK)

If you run an estate — a multi-academy trust, a care or hotel group, a managed portfolio — you are carrying a dozen statutory regimes at once, each on its own clock. Miss a date on any one of them and the consequence isn't an awkward email. It's an enforcement notice, an unlimited fine, an insurer walking away from a claim, and in the worst cases a personal prosecution of whoever was named the duty-holder.

This is the calendar. What each regime is, who's on the hook, and — the part everyone gets wrong — when it's actually due. Where a frequency is risk-based rather than legally fixed, we say so plainly, because pretending otherwise is how teams get caught out.

How to read this calendar

Two distinctions run through everything below.

Hard-dated vs risk-based. A handful of regimes carry a fixed legal interval — get a gas check annually, examine a passenger lift every six months. Most don't. The law instead requires the duty to be discharged "so far as is reasonably practicable" and the assessment kept "suitable and sufficient" or reviewed "regularly". For those, the interval below is the typical industry practice that a competent duty-holder would defend — not a number written in a statute. We flag every risk-based one explicitly.

Residential vs non-domestic. Some intervals (the five-yearly EICR, annual gas check) are legal duties specifically in the private rented sector. In commercial, institutional and education estates the same rhythms are followed as good practice under the governing standard rather than a tenancy-specific regulation. Where that matters, we say which.

Fire Risk Assessment (FRA)

Regime: Regulatory Reform (Fire Safety) Order 2005 (the "RRO"), as amended by the Fire Safety Act 2021 and Building Safety Act 2022.

Who's responsible: the Responsible Person — the employer, owner, or whoever controls the premises. You can delegate the assessment work to a competent assessor; you cannot delegate the duty.

How often: risk-based — no fixed legal interval. The RRO requires the assessment to be kept up to date, reviewed regularly, and redone after any significant change (refurbishment, change of use, new occupancy, an incident). Most estates review annually and fully reassess on any material change. Buildings with a "sleeping risk" — care homes, hotels, student accommodation — sit at the higher-frequency end. Since the Building Safety Act amendments (in force 1 October 2023), the assessment must be recorded in full regardless of premises size.

Why it bites: serious breaches carry unlimited fines and up to two years' imprisonment. The Fire and Rescue Authority enforces it, and prosecutions of landlords, agents and care providers are routine.

Electrical — fixed wiring (EICR)

Regime: in the private rented sector in England, the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020; everywhere else, BS 7671 good practice.

Who's responsible: the landlord or duty-holder for the installation.

How often: fixed wiring inspected and tested at least every five years in the PRS, recorded on an Electrical Installation Condition Report (EICR). Commercial and institutional estates follow the same five-yearly rhythm as good practice. Any C1 (danger present) or C2 (potentially dangerous) finding must be remediated, with written confirmation, within 28 days (or sooner if the report specifies). Note that five years is a maximum — a report can recommend an earlier retest.

Gas safety (CP12)

Regime: Gas Safety (Installation and Use) Regulations 1998.

Who's responsible: the landlord, in rented residential property.

How often: an annual check on every appliance and flue by a Gas Safe registered engineer, recorded on a Landlord Gas Safety Record (the "CP12"), a copy given to the tenant. This is hard-dated and unforgiving — you're non-compliant the day it lapses. You can carry out the check up to two months before the deadline without losing the original anniversary date, which is the only sensible way to avoid drift.

Legionella (ACOP L8 / HSG274)

Regime: the duty flows from the Health and Safety at Work etc. Act 1974 and COSHH, with the detail in the Approved Code of Practice L8 and the technical guidance HSG274.

Who's responsible: the duty-holder — typically the employer or person in control of the premises.

How often: risk-based. You need a legionella risk assessment, a written control scheme, and ongoing monitoring (temperature checks, flushing of little-used outlets, sampling where appropriate). The risk assessment should be reviewed periodically — commonly every two years, or sooner if the water system, its use or the building changes. There is no single legally mandated interval for the assessment itself; the duty is to keep control measures effective and the assessment current.

Asbestos — management survey and re-inspection

Regime: Control of Asbestos Regulations 2012 (CAR 2012), regulation 4 — the duty to manage.

Who's responsible: the duty-holder for non-domestic premises and the common parts of residential blocks.

How often: there's no fixed survey interval, but the duty is continuous. You must find out whether asbestos-containing materials (ACMs) are present, keep an asbestos register, assess the risk, and maintain a written management plan. ACMs in the register should be re-inspected periodically — commonly every 6 to 12 months depending on their condition and likelihood of disturbance, with the plan reviewed at least annually. Any building constructed or refurbished before 2000 should be presumed to contain asbestos until a survey proves otherwise.

Lifts and lifting equipment (LOLER)

Regime: Lifting Operations and Lifting Equipment Regulations 1998 (LOLER).

Who's responsible: the duty-holder for the equipment.

How often: a thorough examination by a competent person — every six months for equipment that lifts people (passenger lifts), and every twelve months for other lifting equipment (or to an examination scheme drawn up by a competent person). Reports go on file and defects must be acted on without delay.

Emergency lighting (BS 5266)

Regime: the RRO requires adequate emergency escape lighting; the supporting standard is BS 5266.

Who's responsible: the Responsible Person, as part of fire-safety arrangements.

How often: monthly brief functional tests and a full-duration annual test (a three-hour discharge test for most systems), all logged. This is industry practice flowing from the standard rather than a statutory number, but a missing log is exactly what an enforcing authority looks for.

Fire alarm and detection (BS 5839)

Regime: the RRO requires appropriate detection and warning; the supporting standard is BS 5839.

Who's responsible: the Responsible Person.

How often: a weekly user test of a different call point, periodic servicing by a competent engineer — typically every six months, and a documented log throughout. Again, practice from the standard rather than a fixed legal interval, but undocumented servicing is a common finding.

Energy Performance Certificate (EPC) and MEES

Regime: EPC required on build, sale or let; Minimum Energy Efficiency Standards (MEES) on top in the PRS.

Who's responsible: the owner / landlord.

How often: an EPC is valid for ten years. Under MEES it's generally unlawful to let a property rated below E (with limited exemptions). Future tightening of the minimum rating has been signalled repeatedly, so treat your worst-rated stock as a planning problem now, not a certificate to renew later.

Portable appliance testing (PAT)

Regime: Electricity at Work Regulations 1989 — the duty is to keep electrical equipment in a safe condition.

Who's responsible: the employer / duty-holder.

How often: risk-based — there is no legal interval. The law requires equipment to be maintained in a safe condition, full stop. Most organisations run combined inspection and testing on a risk-based schedule (more frequent for portable tools on a building site, less so for fixed office IT) and keep the records. The absence of a fixed frequency is not an excuse for having no system.

Air conditioning inspection (TM44)

Regime: Energy Performance of Buildings (England and Wales) Regulations 2012; the inspection methodology is CIBSE TM44.

Who's responsible: the person who controls the air-conditioning system.

How often: systems with an effective rated output over 12 kW must be inspected by an accredited energy assessor at least every five years, with the report lodged on the central register.

F-Gas

Regime: the GB F-Gas Regulation (assimilated from EU 517/2014).

Who's responsible: the operator of the equipment (refrigeration, air conditioning, heat pumps).

How often: risk-based on charge size. Leak checks scale with the CO₂-equivalent charge — broadly every twelve months above 5 tonnes CO₂e, every six months above 50 tonnes, and every three months above 500 tonnes, with intervals halved or doubled depending on whether a leak-detection system is fitted. Records of refrigerant type, quantity and checks must be kept.

Why estates fall out of compliance

Almost nobody fails on a regime they'd never heard of. Buildings slip for boring, preventable reasons:

• No owner. The obligation existed; nobody was named to it.
• Dates in someone's head. Renewals in a spreadsheet, or nowhere, with no early warning.
• Findings, not certificates. The certificate was filed; the C2 remedial it flagged was never closed.
• No paper trail. When the regulator says "show me", there's nothing to show.

The fix is the same whether or not you use software: one register of every building × regime, a named responsible person on each, computed next-due dates, escalating reminders well before expiry, and the underlying certificate and its findings attached.

The regime that catches the most teams is fire, because its interval is risk-based and easy to let drift — we've broken it down in detail for the education sector in Fire Risk Assessment for schools and multi-academy trusts.

Frequently asked questions

Which of these intervals are legally fixed, and which are risk-based?

Genuinely fixed by law: the annual gas check (PRS), the five-yearly EICR (PRS) and TM44 (over 12 kW), and six-monthly LOLER examinations for passenger lifts. Risk-based — where the law requires "suitable and sufficient", "regularly" or "maintained in a safe condition" rather than a number: fire risk assessments, legionella reviews, PAT, asbestos re-inspection, and the EICR in non-domestic estates. F-Gas leak-check intervals are fixed but depend on charge size. Treat the risk-based ones as the higher liability, not the lower — "no fixed interval" is not a defence for never doing it.

Who is personally liable if a date is missed?

The named duty-holder for that regime — the Responsible Person under fire law, the duty-holder under asbestos and the rest. Liability is personal and, for the most serious fire and health-and-safety breaches, criminal. This is precisely why naming an owner per building per regime, in writing, is the first control to put in place.

What's the single most effective control?

A single register that pairs every building with every regime, names an owner, computes the next-due date from the last certificate, and escalates reminders well before expiry — and that captures the findings on each certificate, not just the certificate itself. Most breaches are a slipped date or an unclosed remedial, both of which a register with early warning prevents.

Where this leaves you

This is a lot to hold, and it never stops moving. That's the actual job: not knowing the regimes exist — you do — but keeping a dozen clocks from quietly running out across every building you control.

Proprietas is built to be that register. Drop in a certificate and it reads the dates, files it to the right property, computes the next-due, and chases the renewal at 90/60/30/7 days so nothing slips — for fire, electrical, gas, legionella and the rest, with the certificate's findings tracked alongside. The same engine feeds issues and work orders when a remedial needs raising. You can try it on one of your own certificates before committing to anything.

This is a plain-English overview, not legal advice — your specific duties depend on your buildings and how they're used.
