How Much Does Landlord Compliance Actually Cost?

One of the most common questions from landlords — especially those scaling from one property to several — is how much compliance actually costs per year. The answer is less than most people assume, and dramatically less than the cost of getting it wrong.

Here is a detailed breakdown of every compliance obligation, what it costs, and what the annualised figure looks like across your portfolio.

Cost breakdown by obligation

Gas safety check (CP12)

Cost: £60–£120 per property
Frequency: Every 12 months
Annualised cost: £60–£120/year
Legislation: Gas Safety (Installation and Use) Regulations 1998

The cost varies by number of gas appliances and your location. Properties with a single boiler sit at the lower end. Some Gas Safe engineers offer multi-property discounts if you have several properties in the same area.

This only applies to properties with a gas supply. If your property is fully electric, you do not need a gas safety check.

Electrical Installation Condition Report (EICR)

Cost: £120–£350 per property
Frequency: Every 5 years
Annualised cost: £24–£70/year
Legislation: Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020

The cost depends on property size and the complexity of the electrical installation. A one-bedroom flat sits at the lower end; a large house with older wiring will be higher.

Important: If the EICR identifies C1 (danger present) or C2 (potentially dangerous) codes, you must pay for remedial work within 28 days. This can range from £100 for a minor fix to several thousand pounds for a rewire. Budget a contingency, particularly for older properties.

Energy Performance Certificate (EPC)

Cost: £60–£120 per property
Frequency: Every 10 years
Annualised cost: £6–£12/year
Legislation: Energy Performance of Buildings (England and Wales) Regulations 2012

An EPC is one of the cheapest compliance items on an annualised basis. You need a rating of E or above to legally let in England and Wales. If your property rates F or G, the cost of improvements to reach E can be significant, but there is a cost cap of £3,500 (inc. VAT) under the current MEES regulations, after which you can register an exemption.

Smoke and carbon monoxide alarms

Cost: £30–£80 initial installation
Frequency: Ongoing — alarms have a 10-year lifespan (smoke) and 5–7 years (CO)
Annualised cost: £5–£15/year (spread over replacement cycles)
Legislation: Smoke and Carbon Monoxide Alarm (Amendment) Regulations 2022

You need smoke alarms on every storey and CO alarms in rooms with fixed combustion appliances (including gas boilers). Mains-wired alarms with battery backup cost £20–£40 each installed. Sealed battery alarms cost £15–£25 each. Replace smoke alarms every 10 years and CO alarms every 5–7 years per manufacturer guidance.

Deposit protection

Cost: £0 (custodial scheme) or approximately £25/year (insured scheme)
Frequency: Per tenancy
Annualised cost: £0–£25/year
Legislation: Housing Act 2004, sections 213-215

Custodial schemes (DPS, mydeposits, TDS) hold the deposit and charge nothing. Insured schemes let you hold the deposit yourself for a fee of around £25 per tenancy.

You must also serve the prescribed information within 30 days — no cost, but failing to do so carries a penalty of one to three times the deposit. See our deposit protection guide for the full requirements.

HMO licence (if applicable)

Cost: £500–£1,500
Frequency: Every 5 years
Annualised cost: £100–£300/year
Legislation: Housing Act 2004, Part 2

Mandatory HMO licensing applies to properties with five or more tenants forming two or more separate households. The licence fee varies by local authority — some London boroughs charge over £1,000, while councils outside London are closer to £500. Additional costs may apply if the council requires fire safety upgrades or extra facilities as licence conditions.

Selective licensing (if applicable)

Cost: £500–£800
Frequency: Every 5 years
Annualised cost: £100–£160/year
Legislation: Housing Act 2004, Part 3

Selective licensing applies where the local authority has designated a scheme — typically areas with high deprivation or poor housing conditions. Check with your local council whether your property falls in a designated area.

Legionella risk assessment

Cost: £100–£250 (if using a specialist assessor)
Frequency: Every 2 years (recommended)
Annualised cost: £50–£125/year
Legislation: Health and Safety at Work etc. Act 1974 and COSHH Regulations

For a standard property with a combi boiler and no stored water, the risk is low and you can carry out a basic assessment yourself using HSE guidance — at no cost. Specialist assessments are more common for properties with hot water tanks or complex plumbing.

Right to Rent check

Cost: £0
Frequency: Before each new tenancy (and follow-up checks for time-limited permission)
Annualised cost: £0
Legislation: Immigration Act 2014, Part 3

Right to Rent checks cost nothing — you verify the tenant's identity documents yourself using the government's free online checking service. But the penalty for skipping it is up to £3,000 per tenant (civil) or up to five years' imprisonment for knowing offences.

Total annual compliance cost per property

Here is what a standard single-let property in England with a gas supply costs to keep compliant each year:

Obligation	Annualised cost
Gas safety check	£60–£120
EICR	£24–£70
EPC	£6–£12
Smoke/CO alarms	£5–£15
Deposit protection	£0–£25
Legionella assessment	£0–£125
Right to Rent	£0
Total	£95–£367/year

For an HMO, add £100–£300/year for the licence. For properties in selective licensing areas, add another £100–£160/year.

Realistic mid-range estimate for a standard single-let property: around £150–£250 per year.

Compare that against penalty costs

The penalties for non-compliance dwarf the cost of getting it right:

Obligation	Maximum penalty
Gas safety breach	£6,000 fine + criminal record
EICR breach	£30,000 fine
EPC breach	£5,000 fine
Smoke/CO alarm breach	£5,000 fine
Deposit protection breach	1–3x deposit compensation
HMO licence breach	£30,000 fine + rent repayment order
Right to Rent breach	£3,000 per tenant

A single gas safety fine wipes out decades of gas safety check costs. A single EICR penalty exceeds what you would spend on electrical inspections across the property's lifetime.

Multi-property scaling

If you own multiple properties, compliance costs scale linearly — but there are efficiencies. Gas engineers and electricians often discount for batch inspections across several properties. Deposit protection stays at £0 with custodial schemes regardless of portfolio size.

For a five-property portfolio of standard single-lets, budget roughly £750–£1,250 per year total — around £150–£250 per property, a fraction of the rental income.

Budget for it, track it, stay ahead

Compliance costs are predictable. Gas safety is annual, EICR every five years, EPC every ten. The landlords who get caught out are not the ones who cannot afford compliance — they are the ones who lost track of when things expire.
