Every residential rental property in England must hold three valid certificates at all times. Letting a property without any one of them puts you in breach of the law, exposes you to significant financial penalties and — in the case of a gas or electrical incident — potential criminal liability.
Under the Gas Safety (Installation and Use) Regulations 1998, landlords must arrange an annual gas safety inspection of every gas appliance in their rental property. The inspection must be carried out by a Gas Safe registered engineer. The resulting certificate — the CP12 — must be renewed every year and provided to existing tenants within 28 days of the inspection, and to new tenants before they move in.
Annual gas safety check by a Gas Safe registered engineer
— CP12 certificate issued and retained for a minimum of two years
— Copy provided to existing tenants within 28 days of the check
— Copy provided to new tenants before occupation begins
— Records of the previous two years' certificates available on request
Failure to hold a valid CP12 is a criminal offence under the Gas Safety (Installation and Use) Regulations 1998. Landlords can face fines of up to £6,000 per breach, up to six months imprisonment, and invalidation of their building and contents insurance. Where a tenant suffers harm as a result of a gas incident at an uncertified property, the landlord can face manslaughter charges.
Our Gas Safe registered engineers carry out annual CP12 inspections across London and the surrounding areas. Certificates are issued on the day and uploaded immediately to your DK Lettings client portal. We track your renewal dates and notify you before your certificate lapses — so you are never caught out.
Since April 2021, an EICR has been a legal requirement for all privately rented properties in England under The Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020. The inspection must be carried out by a qualified and competent electrician. The report must be renewed at least every five years — or at the start of each new tenancy — and a copy must be provided to tenants before they move in and to the local authority within seven days if requested.
EICR inspection every five years or at the start of each new tenancy
— Inspection carried out by a qualified, competent and NICEIC-accredited electrician
— Copy provided to new tenants before occupation — Copy provided to existing tenants within 28 days of the inspection
— Copy provided to the local authority within seven days if requested
— Any C1 or C2 faults resolved within 28 days, with written confirmation to tenants and local authority
Local authorities can impose fines of up to £30,000 per property for failure to hold a valid EICR or failure to carry out remedial works within the required timeframe. Local authorities also have the power to carry out the remedial works themselves and recover the cost from the landlord.
Our NICEIC-accredited electricians carry out EICR inspections across London and the surrounding areas. Reports are issued the same day and uploaded to your client portal. If remedial works are required, our own electricians carry them out — you do not need to source a separate contractor. Once remedial works are complete, we retest, issue an updated satisfactory report and document everything in your portal.
C1 — Immediate danger. The electrical installation poses an immediate risk. The property cannot be legally let until the issue is resolved. DK Lettings will carry out emergency remedial works on the same visit where possible.
C2 — Potentially dangerous. There is a potential risk that must be resolved within 28 days. The landlord must confirm completion in writing to both the tenant and the local authority.
C3 — Improvement recommended. The installation does not meet current standards but does not pose an immediate or potential danger. The report will still be marked satisfactory. Improvements are advisable but not legally required.
FI — Further investigation required. The electrician requires more information to fully assess the issue. Further testing will be needed before a full report can be issued.
An EPC rates a property's energy efficiency on a scale from A (most efficient) to G (least efficient). All rental properties in England must hold a valid EPC and must achieve a minimum rating of E before being let. EPCs are valid for ten years, but a new certificate is required if significant energy efficiency improvements are made to the property.
Valid EPC held at all times for any rental property — Minimum rating of E — properties rated F or G cannot legally be let — Copy provided to prospective tenants before marketing the property — EPC lodged on the national register
Under the Minimum Energy Efficiency Standards regulations, landlords cannot legally let a property with an EPC rating below E. The government has indicated that the minimum standard is likely to rise to a C rating in the coming years — landlords with lower-rated properties should consider energy efficiency improvements proactively to avoid future enforcement action and potential fines of up to £30,000.
Letting a property without a valid EPC or with a rating below E is illegal. Local authorities can impose fines of up to £5,000 for non-compliance, rising to £30,000 when updated regulations come into force. Landlords who fail to hold a valid EPC also lose the right to serve a Section 21 notice to end a tenancy.
DK Lettings does not currently carry out EPC assessments directly — EPC inspections must be conducted by an accredited domestic energy assessor. However, our compliance packages and client portal track your EPC expiry dates alongside your CP12 and EICR, so you always know where every property stands. We are happy to advise on improving your property's energy rating through heating system upgrades and can recommend accredited EPC assessors in your area.
An annual boiler service is not a legal requirement for landlords — but it is strongly recommended. Regular servicing catches problems early, maintains efficiency, and provides a documented service history that protects you if a dispute arises. Every boiler service and repair is logged to your DK Lettings client portal.
Since October 2022, landlords in England are legally required to install a carbon monoxide alarm in any room containing a fixed combustion appliance — this includes gas boilers and gas fires, but not gas cookers. Alarms must be in working order at the start of each tenancy. DK Lettings engineers check and advise on carbon monoxide alarm placement during every gas safety inspection.
Landlords must install at least one smoke alarm on every storey of the property that is used as living accommodation. Alarms must be tested and confirmed as working at the start of each tenancy.
Landlords have a duty under the Health and Safety at Work Act 1974 and the Control of Substances Hazardous to Health Regulations to assess and manage the risk of legionella in their properties. This does not require a formal certificate but should be documented and reviewed regularly, particularly in properties with complex water systems.
A landlord cannot legally serve a Section 21 notice to end an assured shorthold tenancy unless they have provided the tenant with a valid EPC, a current CP12 gas safety certificate, and the government's How to Rent guide. Failure to provide any of these documents invalidates the Section 21 notice entirely.
Awaab's Law, introduced under the Social Housing (Regulation) Act 2023, currently applies to social housing providers and requires landlords to investigate hazards within 14 days, begin emergency repairs within 24 hours and complete them within seven days. While it does not yet apply directly to private landlords, it signals clearly where regulation is heading.
The pattern across UK housing legislation over the last decade has been consistent — standards that begin in social housing eventually extend to the private rented sector. Landlords who take a proactive approach to compliance now, with documented inspection histories and responsive maintenance records, are significantly better positioned when new obligations arrive.
DK Lettings keeps a full documented record of every inspection, every remedial action and every engineer attendance in your client portal — building the compliance history that protects you both now and as regulation evolves.

Every 12 months. The CP12 must be renewed annually and provided to tenants within 28 days of the inspection. New tenants must receive a copy before they move in. DK Lettings tracks renewal dates for every property in your portfolio and notifies you when a certificate is due.
At least every five years, or at the start of each new tenancy — whichever comes first. Since April 2021 this has been a legal requirement for all privately rented properties in England.
Yes. Non-compliance with the Gas Safety (Installation and Use) Regulations 1998 is a criminal offence. Landlords can face fines of up to £6,000 per breach, up to six months imprisonment and insurance invalidation. In cases where a tenant is harmed, manslaughter charges are possible.
Local authorities can impose fines of up to £30,000 per property for failure to hold a valid EICR or failure to carry out required remedial works within the specified timeframe.
No. A property with C1 or C2 codes is classified as unsatisfactory and cannot legally be let until the issues are resolved. C1 faults must be resolved immediately. C2 faults must be resolved within 28 days, with written confirmation provided to the tenant and local authority. DK Lettings carries out all remedial works and issues an updated satisfactory report once complete.
Yes. Since October 2022, landlords in England must install a carbon monoxide alarm in every room containing a fixed combustion appliance — including rooms with gas boilers and gas fires. Alarms must be in working order at the start of each tenancy.
A Section 21 notice is invalid if the landlord has not provided the tenant with a valid EPC, a current CP12 gas safety certificate, and the government's How to Rent guide. Missing any one of these documents means a Section 21 cannot be legally served until the situation is remedied.
Not yet. Awaab's Law currently applies to registered social housing providers. However, the direction of UK housing regulation strongly suggests that similar obligations will extend to the private rented sector in the coming years. Landlords who maintain thorough compliance records now will be well prepared when that happens.
Yes. Our portfolio compliance plans are designed for landlords managing multiple properties and letting agents managing multiple clients.
