The local-authority enforcement layer that landlords face changed on 1 May 2026. Before that date, councils issuing civil-penalty notices worked from the Housing and Planning Act 2016 framework, with a £30,000 ceiling, the gov.uk statutory guidance dated to the older regime, and an offence list drawn principally from Housing Act 2004 licensing breaches and the HP Act 2016 banning-order offences. From 1 May 2026, the Renters' Rights Act 2025 sections 15 to 17 plus Schedule 5 provide a parallel civil-penalty track with a £40,000 ceiling and a substantially expanded offence list that includes Landlord Redress Scheme non-membership, PRS Database non-registration (once that Part is fully commenced), the new re-letting prohibition after possession on landlord-sale grounds, the bidding-wars and advance-rent prohibitions, and the discrimination protections. For roughly the next two to three years, landlords will see notices from both regimes (depending on when the relevant offence is treated as committed), and the defence response has to work in both directions.

This page is the defence-side companion to our tax-implications page on the Act as a whole, together with our companion pages on PRS Database and Ombudsman registration mechanics (pre-enrolment compliance) and the Decent Homes Standard PRS compliance checklist. The aim here is narrower and operationally specific: what to do when a notice arrives, how the procedural windows work, what succeeds at the First-Tier Tribunal Property Chamber, when a banning order becomes a realistic risk, and what the consequential tax position looks like once the underlying matter has settled.

The 1 May 2026 bifurcation, why dates matter

The Commencement No. 2 and Transitional and Saving Provisions Regulations 2026 (SI 2026/421) appointed 1 May 2026 as the day on which the substantive RRA 2025 enforcement provisions came into force. The earlier SI 2025/1354 had brought in preparatory provisions on 27 December 2025 (regulation-making powers, enforcement-authority designations, parts of Schedule 4 covering Decent Homes preliminary matters), but the operational civil-penalty regime, the new offence list, the £40,000 ceiling, and the procedural framework in Schedule 5 all crystallised on 1 May 2026.

The gov.uk civil-penalties guidance that local authorities have relied on since 2018 (Civil Penalties under the Housing and Planning Act 2016) was rescoped on 1 May 2026 to apply only to offences committed before that date. A parallel gov.uk page covering civil penalties under the Renters' Rights Act 2025 now governs the post-1-May-2026 cohort. Both branches remain live: the Housing and Planning Act 2016 regime continues to apply to its surviving offence base, and the older regime's appeal route (Schedule 13 of the HP Act 2016) remains intact for those notices.

The practical point for a landlord opening a notice of intent letter is to look at the date of the underlying conduct rather than the date on the notice itself. A notice issued in October 2026 for a deposit-protection breach in 2024 falls under the older £30,000 regime. A notice issued in October 2026 for a PRS Database non-registration in August 2026 (assuming the Database Part is in force by then) falls under the new £40,000 regime. The bifurcation matters for the ceiling, for the appeal procedure, and for which gov.uk statutory guidance the authority should have followed in scoring the penalty.

The notice-of-intent letter, what it must contain

Schedule 5 to the RRA 2025 sets the contents requirements for a notice of intent. The authority must, in writing: identify the landlord (and any connected persons being considered), particularise the offence or offences alleged with sufficient detail for the landlord to understand the case, set out the proposed penalty amount, give the authority's reasons including reference to its published civil-penalty policy, and inform the landlord of the right to make written representations within 28 days starting with the day after the notice is given.

The procedural elements above are not formalities. The First-Tier Tribunal Property Chamber has cancelled penalties on appeal where the notice failed to particularise the offences (the landlord could not adequately respond), where the reasons for quantum were templated and did not engage with the specific facts (the authority's policy had not in fact been applied), or where the representations window had not been clearly conveyed. The first thing to check on receipt is therefore not the figure but the procedural compliance of the notice itself.

The older Schedule 9 HA 2004 / Schedule 1 HP Act 2016 framework continues to govern pre-1-May-2026 notices and applies an essentially similar process. The substantive defence and procedural compliance grounds are the same: it is the offence list and the penalty ceiling that differ.

The 28-day representations window

The representations stage is the single highest-leverage moment in the whole defence process. It is the only chance to put evidence and argument in front of the local authority before it issues the final notice. It also fixes the record for any subsequent appeal: matters not raised in representations can be raised at the Tribunal, but the Tribunal will often give less weight to them on the basis that the authority did not have the opportunity to consider them.

Effective representations typically cover four blocks. First, jurisdictional challenge: was the conduct in fact an offence under the cited statute, did it occur in the local authority's area, was the landlord the person responsible (not a managing agent, not a former landlord on a transferred portfolio), is the date of the alleged offence inside the limitation period (six months from the authority becoming aware, on the magistrates'-court statutory model). Second, substantive defence on the facts: documentary evidence that contradicts the authority's account. Third, mitigation on the penalty quantum: factors that the authority's own published policy treats as reducing the score (first offence, prompt remediation, cooperation, no aggravating features). Fourth, procedural challenge: defects in the notice itself, breach of the authority's own policy, breach of natural justice.

A common procedural lever is the authority's civil-penalty scoring matrix. Every authority is required to have a published policy under section 23 HP Act 2016 (or, post-1-May-2026, under section 16 RRA 2025), setting out how it allocates penalties across bands by reference to culpability, harm, and aggravating / mitigating factors. The matrix usually produces a numerical score that maps to a band. Where the authority's notice quantum does not align with the score the matrix would produce on the facts, the disparity is a representations point: either the score has been computed wrongly, or the authority has departed from its policy without giving reasons (which is an administrative-law error).

From final notice to First-Tier Tribunal appeal

The final notice is the formal imposition of the penalty. It restarts the clock on a fresh 28-day window, this time for appeal to the First-Tier Tribunal Property Chamber. Schedule 5 Para 11 RRA 2025 sets the appeal grounds in three categories: the offence was not committed, the penalty quantum is excessive or otherwise unreasonable, or the procedural requirements were not complied with. The Tribunal hears the matter de novo and can confirm, vary, or cancel the penalty.

The Property Chamber does not generally award costs against the losing party. Each side bears its own legal costs absent unreasonable conduct (Rule 13 of the Tribunal Procedure Rules). The hearing is normally a one-day matter, conducted by a panel of one or two members (a legally qualified Tribunal Judge and, where the issue is complex, a surveyor or valuer member). Decisions are published anonymised after the hearing.

The practical takeaway: the cost of running a Tribunal appeal (housing counsel's fees, expert reports if needed, hearing day) is usually in the £6,000 to £15,000 range for a single penalty case, depending on complexity. That makes the appeal a sensible economic option for penalties at the upper end of the band (where the penalty figure itself exceeds the appeal costs) and a marginal one for smaller penalties (£2,000 to £5,000 range), where the cost of appeal can exceed the penalty saving. The economic calculus shifts where the penalty also brings collateral consequences: discretionary database listing after two penalties in 12 months, banning-order risk, ongoing-letting disruption.

Banning orders, the higher-stakes track

A banning order is a different order of severity from a civil penalty. Section 14 of the Housing and Planning Act 2016 (preserved by the RRA 2025 transitional provisions and applied to the new RRA offence list) defines a banning order as an order prohibiting the named person from letting housing in England, engaging in letting agency work, or engaging in property management work, for a period set by the Tribunal. The minimum duration is 12 months under section 17; there is no statutory maximum.

The application is brought by a local housing authority to the First-Tier Tribunal Property Chamber. The authority has to show, on the balance of probabilities, that the landlord has been convicted of a banning-order offence (the section 40 list, expanded post-1-May-2026 by Schedule 4 RRA 2025 to capture the new RRA offences) or has received two civil penalties for banning-order offences within a 12-month period. The Tribunal then considers whether to make the order and, if so, what duration is appropriate having regard to the seriousness of the conduct, evidence of insight, risk of repetition, and any earlier enforcement history.

The collateral consequences of a banning order are substantial. The landlord cannot let any property in England, directly or through a controlled corporate vehicle, for the duration of the ban. The HP Act 2016 anti-avoidance provisions extend the ban to connected persons who knew or ought to have known of the order, so transferring the portfolio to a spouse, adult child, or family company to continue trading is not a viable route around the order. The landlord must be entered on the rogue-landlord database under section 29 (mandatory inclusion following a banning order). Selling the property is permitted; trading via the same legal personality is not. Breach of a banning order is a criminal offence under section 21 carrying up to 51 weeks' imprisonment or an unlimited fine, plus a further civil penalty under section 23 of up to £40,000.

The defence strategy at a banning-order application is materially different from a civil-penalty appeal. The Tribunal is not constrained by an existing penalty notice and is making the order in the round on the application's evidence base. The landlord's representations focus more heavily on insight, remediation, professional support engaged since the underlying conduct, business changes that reduce the risk of repetition, and the proportionality of the order against the conduct. Tribunal decisions show ranges from 12-month orders for single-conviction first-offence cases through to lifetime bans for organised conduct, repeat illegal eviction, or violence-against-tenant cases.

The rogue-landlord database versus the PRS Database, two parallel registers

Landlords often conflate the two registers. They are different things.

The Database of Rogue Landlords and Property Agents was established by section 28 of the HP Act 2016 and is operated by the Secretary of State for the use of local housing authorities and the Database operator. Inclusion is either mandatory (under section 29 following a banning order in force) or discretionary (under section 30 after a conviction for a banning-order offence or two civil penalties within 12 months for banning-order offences). The database is not, in its current statutory form, publicly accessible: it is a tool for enforcement coordination across authorities. Discretionary inclusion can be appealed under section 32 to the First-Tier Tribunal. Entries normally have a 2-year minimum duration under section 35, with extension if circumstances warrant. The RRA 2025 preserves this database in its current form for the moment.

The Private Rented Sector Database is a different and separate register, established by Chapter 3 of Part 2 of the RRA 2025 (sections 75 to 96). Every PRS landlord in England will be required to register on the PRS Database before letting any property; the registration captures landlord ID, property addresses, and compliance status (gas safety certificate dates, EICR, EPC, deposit protection scheme details, Right-to-Rent records). The PRS Database is public-facing for compliance information at the property level and is the structural backbone for tenant protections (a property cannot be the subject of a Section 8 possession claim unless it is registered, per section 90). As at 2026-05-22 the PRS Database Part is enacted but no commencement order has been made appointing the day on which registration becomes mandatory; government policy statements anticipate commencement before April 2027 but the operative SI is the source of truth.

The two registers will run in parallel. Most landlords will appear only on the PRS Database (because every PRS landlord must register). A small subset (those subject to banning orders or with the requisite enforcement history) will additionally appear on the rogue-landlord database. The defence implication is that a single enforcement event can produce listings on both, with different visibility profiles and different appeal routes.

Three anonymised enforcement scenarios

The following scenarios are composites for illustration. None describes an actual client.

Scenario one, deposit-protection-breach civil penalty. Mr Patel has a six-property portfolio in a Midlands borough. A tenant complaint in March 2026 surfaces that one deposit was not protected within 30 days of receipt in 2024. The council issues a notice of intent on 5 May 2026 alleging an offence committed in 2024, with a proposed penalty of £15,000 under the HP Act 2016 regime (£30,000 ceiling). Representations within the 28-day window show: first offence for this landlord, deposit protected belatedly once the issue was identified, tenant repaid in full at end of tenancy with interest, full cooperation with the inspection, no aggravating factors. The council's scoring matrix would produce a band-3 figure of around £6,000 to £8,000 on these facts. The final notice comes in at £7,500. The landlord pays without appeal. Tax position: the penalty itself is not deductible; the £2,400 legal fees paid to specialist housing counsel on the representations are deductible as a revenue expense of the rental business (the underlying matter was a routine compliance breach, not a banning-order-track event).

Scenario two, post-1-May-2026 advance-rent prohibition penalty. A small letting-agency client, the Singh family company, lets a property in July 2026 having accepted three months' rent in advance from a corporate-tenant relocation case. Section 9 RRA 2025 prohibits demand or acceptance of rent more than one month in advance once the new regime is in force, with no general carve-out for corporate tenants outside the small list of regulated exceptions. A local authority opens an enforcement file on tenant referral; the notice of intent is for £8,000 under the RRA 2025 regime. Representations argue (a) the corporate tenant scenario was not what the section was designed to capture, (b) the family company acted on letting-agent advice, (c) no harm to a vulnerable tenant. The final notice comes in at £4,000. The landlord pays. No appeal because the figure no longer justifies the appeal cost. Tax position: penalty not deductible; £1,800 legal fees deductible.

Scenario three, banning-order application after repeated illegal eviction. Mr Hassan owns two HMOs in a London borough. A tenant complaint and police-attended incident in February 2026 surface an illegal eviction (changed locks, removed possessions, no Court order). The council prosecutes successfully in July 2026 under section 1 of the Protection from Eviction Act 1977 (Crown Court fine plus criminal record). The same authority then applies for a banning order under section 14 HP Act 2016 on the basis of the section 40 banning-order-offence conviction. The Tribunal hearing in late 2026 imposes a 3-year banning order; the landlord is entered on the rogue-landlord database under section 29; he must dispose of the portfolio or transfer management to an unconnected party for the duration of the ban. Tax position: the legal fees defending the banning-order application are arguably capital in nature (preserving the right to carry on the business) and HMRC's position is normally that such fees are not deductible against current rental income. The criminal fine is not deductible. Sales-driven disposals during the ban interact with the CGT position; the portfolio-disposal CGT mechanics are covered in our companion page on the tax implications of landlords selling their portfolio post-RRA 2025.

The tax-deductibility position on enforcement costs

Three different categories of expenditure arise in enforcement matters, and they have three different tax treatments.

The civil penalty or criminal fine itself is not deductible. HMRC's long-standing position, summarised at BIM38500, is that penalties for breach of regulatory obligations fail the wholly-and-exclusively test and are not allowable against profits of a trade or property business. The same applies to Rent Repayment Orders: the order is not an expense of the rental business in the deductible sense but a reversal of previously received rental income. The accounting treatment is to reduce the rental income in the year the RRO is made, which produces a deduction only to the extent that the RRO exceeds the rent receivable.

Legal fees defending a civil-penalty notice are normally deductible where the underlying matter is a routine compliance breach with revenue character (deposit protection, HMO standards, selective licence late application). The fees are an incidental cost of operating the rental business and pass the wholly-and-exclusively test. Where the matter expands into a banning-order application or a criminal prosecution, the character of the fees shifts towards the capital end of the spectrum (preserving the right to carry on the business rather than dealing with a routine operating matter), and the deduction becomes harder to support. Sessions advising on borderline cases should document the specific scope of the legal work invoiced (notice-of-intent representations versus banning-order defence versus criminal defence) so that the rental-business portion can be ring-fenced even where the wider work is non-deductible.

Remediation expenditure is the third category. Where the breach is a property-condition issue (Decent Homes Standard, HHSRS Category 1 hazards), the costs of bringing the property back up to standard are deductible to the extent that they are repair (revenue) and capitalised to the extent they are improvement (capital). The repair-versus-improvement boundary is unchanged by the enforcement context: a like-for-like roof repair driven by an improvement notice is still a repair; a roof upgrade to substantially better materials is still an improvement. Our complete deductions list covers this boundary in detail.

Compliance checklist that materially reduces enforcement risk

Pre-emption is cheaper than defence. The checklist below maps to the most-frequent enforcement triggers seen in current Tribunal decisions.

  • Gas safety certificate in date for every property let; copy provided to every new tenant before move-in; renewal diary set 12 months ahead.
  • Electrical installation condition report (EICR) in date (5-year cycle); remedial works completed within 28 days where the report identifies C1 or C2 defects; copy provided to tenants.
  • Energy performance certificate valid (10 years); minimum E rating (the regulations governing minimum energy efficiency standards for private rented properties continue to apply alongside the Decent Homes Standard).
  • Deposit protection in an approved scheme within 30 days of receipt; prescribed information served on the tenant within the same 30-day window.
  • Right-to-Rent checks documented for every tenant; copies retained for at least 12 months after the tenancy ends.
  • How-to-Rent guide served at start of tenancy and on every renewal where the document has been updated.
  • HMO licence in place where the property is a mandatory or additional licensable HMO; selective licence in place in the relevant designated areas.
  • PRS Database registration in place once the relevant Part of the RRA 2025 is commenced; status fields kept current (within 28 days of any change to gas safety certificate, EICR, EPC, or deposit-scheme details).
  • Landlord Redress Scheme / PRS Ombudsman membership in place once required (section 67 RRA 2025); membership certificate retained.
  • Property condition meets Decent Homes Standard (HHSRS Category 1 free, reasonable repair, reasonably modern facilities, reasonable thermal comfort); inspection diary documents the annual self-assessment.

A self-assessment against the checklist once a year, with documentary evidence held centrally rather than scattered across letting agents and property managers, is the single most cost-effective enforcement-risk reduction step a portfolio landlord can take. The local-authority enforcement teams that issue notices are working from precisely this checklist when they investigate; the evidence file you assemble pre-emptively is the evidence file you need to file at representations stage if a notice ever arrives.

When to engage a solicitor, when to engage an accountant

The two professional skill sets are different and the line is often blurred. A specialist housing solicitor handles the procedural defence: drafting representations, assembling the legal-defence file, advising on Tribunal strategy, attending the appeal hearing, advising on banning-order procedure. The accountant or property-tax adviser handles the tax-side question: deductibility of the legal fees, classification of remediation expenditure (revenue versus capital), interaction with CGT on a forced or accelerated disposal, treatment of RRO awards in the rental computation, and (in banning-order cases) the wind-down or transfer of the portfolio.

For a routine civil-penalty case in the £5,000 to £15,000 range, both professional inputs are typically warranted but the volume of accountant work is modest (post-event tax treatment of the fees and the penalty). For a banning-order application or a Tribunal appeal on a larger penalty, the legal cost is the dominant item and the accountant's role is more advisory than executional. For a portfolio-wide enforcement case (multiple notices, multiple properties, possible business-restructure decisions), the two roles run in parallel from the start.

The next step

If you have received a notice of intent, the 28-day clock is the binding constraint. If you have not yet received a notice but are aware of an open complaint or a pending inspection, the pre-emption window is still open and the cost of action now is materially lower than the cost of defence later. Either way, getting the documentary file straight and the legal-defence position established early is the single most valuable thing a landlord facing the new enforcement regime can do.
