Fire Safety Certificates for Houses

When sellers start preparing to put their home on the market, fire safety documentation is one of the areas that can cause confusion. Unlike an Energy Performance Certificate (EPC), there is no single fire safety certificate that all sellers must obtain. But that does not mean the subject can be ignored.

For many houses, fire safety questions will surface through the TA6 Property Information Form and the buyer's solicitor's enquiries. Whether documentation is needed depends on the property's age, any works that have been carried out, and whether it has ever been used for anything other than single-family occupation. This guide explains when fire safety documents are relevant, which regulations apply, and what to prepare for your buyer.

Is there a fire safety certificate for houses?

The short answer is no — not in the sense of a compulsory certificate required for all residential sales. The term “fire safety certificate” is most commonly associated with:

• Fire Certificates (now abolished). Until 2006, fire certificates were required for certain buildings under the Fire Precautions Act 1971. These applied to hotels, factories, and other non-domestic premises — not to private dwellinghouses. Following the Regulatory Reform (Fire Safety) Order 2005, fire certificates were replaced by a system of self-assessed fire risk assessments and the legislation was repealed.
• HMO (house in multiple occupation) licences. If a property has previously been licensed as a HMO, the licensing authority will have imposed fire safety conditions as part of the licence. Documentation of this is relevant if you are selling a former or current HMO.
• Building Regulations Completion Certificates. These are not fire safety certificates per se, but for any works that affected fire compartmentation, escape routes, or fire detection, the Completion Certificate confirms compliance with Part B of the Building Regulations (fire safety). This is the document most commonly needed in residential sales.

If someone asks whether your house has a “fire safety certificate”, they are usually asking about one of the above, most likely a Building Regulations Completion Certificate covering extension or conversion works.

Building Regulations Part B: fire safety for houses

The main fire safety framework for houses in England and Wales is Approved Document B (fire safety), which forms part of the Building Regulations. Part B covers:

• Means of escape. The requirement for a safe route from every part of the house to a final exit. This becomes especially important when a loft conversion or extension adds habitable rooms on a new floor level.
• Internal fire spread (linings). Restrictions on the use of materials on walls and ceilings that would allow fire or flame to spread rapidly.
• Internal fire spread (structure). Requirements for fire-resisting construction between different parts of a building, known as fire compartmentation.
• External fire spread. Provisions governing the proximity and construction of external walls and roofs to reduce fire spreading between properties.
• Access and facilities for the fire service. Vehicle access and facilities such as fire mains that enable the fire service to operate effectively.

When a homeowner carries out structural works that require Building Regulations approval — such as a loft conversion, extension, garage conversion, or internal wall removal — the local authority Building Control department or an Approved Inspector checks that Part B requirements are met. A Completion Certificate (also called a Final Certificate) is issued when the works are signed off. This is the document buyers and their solicitors want to see.

For guidance on what happens when this certificate is missing, see our article on missing Building Regulations sign-off.

When does a house sale involve fire safety documentation?

Fire safety documentation is most likely to be relevant in the following scenarios:

Loft conversions

A loft conversion is the single most common trigger for fire safety questions in a house sale. Adding a habitable room above the existing top floor changes the means of escape requirements significantly. Part B typically requires:

• A protected escape route from the loft room to the final exit, usually achieved by enclosing the staircase with fire-resisting construction.
• Interlinked mains-wired smoke alarms on each floor, including the new loft level.
• Fire doors (typically FD30S — 30-minute fire-resistant with smoke seals) on habitable rooms off the protected staircase.
• A fire-resisting ceiling below the loft room to provide a degree of compartmentation.

A Building Regulations Completion Certificate for the conversion confirms all of this was in place and inspected. Without it, buyers and their solicitors have no certainty that the conversion meets the required standard. See our guide on selling a house with a loft conversion for a full overview of the documentation involved.

Extensions and garage conversions

Extensions and garage conversions that create new habitable rooms also fall within Part B requirements. The specific obligations depend on the size and nature of the works, but fire-resisting construction between an integral garage and the main house is a standard requirement. If the extension creates a new means of escape (for example, a rear door from a bedroom), this will also have been assessed. Our guide on selling a house with an extension covers the documentation requirements in detail.

Previously rented properties or HMOs

If your house has been rented out as a standard single let, fire safety obligations under the Smoke and Carbon Monoxide Alarm (England) Regulations 2022 required working smoke alarms on every storey and carbon monoxide alarms in rooms with a fixed combustion appliance. These regulations apply to landlords; when selling, documentation that the alarms were installed and tested at the start of each tenancy is good practice to retain.

If the property was previously operated as a house in multiple occupation (HMO), significantly more documentation is relevant. Licensed HMOs must meet specific fire safety standards as a condition of licensing, typically including:

• A formal fire risk assessment carried out by a competent person.
• Interlinked, mains-wired smoke detection throughout the property.
• Fire doors to all habitable rooms and escape routes.
• Emergency lighting in larger HMOs (typically those with five or more occupants).
• Fire extinguisher and fire blanket provision (requirements vary by local authority).

If the HMO licence has expired and the property is now being sold, buyers' solicitors will want to see the fire risk assessment and any relevant compliance certificates. Missing documentation for a former HMO can delay a sale significantly.

Scotland: interlinked alarm legislation

Scotland introduced a legal requirement for all homes — including owner-occupied properties — to have interlinked fire and smoke alarms installed. The law, which came into force on 1 February 2022 under the Housing (Scotland) Act 2014 (as amended by the Building (Scotland) Amendment Regulations 2021), requires:

• One smoke alarm in the room most frequently used for general daytime living.
• One smoke alarm in every circulation area on each storey.
• One heat alarm in the kitchen.
• All alarms to be interlinked so that when one activates, all activate.
• Carbon monoxide detectors in rooms with a carbon-fuelled appliance.

Scottish sellers should ensure their property meets these requirements before listing. While there is no formal certificate issued, buyers and their solicitors may ask about compliance, and estate agents may flag non-compliance as a condition of listing.

The Regulatory Reform (Fire Safety) Order 2005: does it apply to houses?

The Regulatory Reform (Fire Safety) Order 2005 (RRO) is the primary fire safety legislation in England and Wales. It replaced the old fire certificate regime and introduced the current system of self-assessed fire risk assessments.

The RRO applies to non-domestic premises and the common areas of multi-occupied residential buildings (such as the corridors, stairways, and communal areas of purpose-built blocks of flats). It does not apply to the parts of a building used solely as a private dwelling.

This means that selling a standard house does not require a fire risk assessment under the RRO. However, if your property has a separately let flat (above a shop, or within an annexe, for example), the landlord duties under the RRO would have applied to the non-domestic or communal elements during any period of letting.

The Building Safety Act 2022 strengthened the fire safety regime for higher-risk residential buildings (those of 18 metres or above, or with at least seven storeys). These provisions primarily affect building owners and managers of multi-storey residential blocks and are not relevant to the typical house sale.

What to include in your property information pack

When preparing to sell, it is worth gathering any fire safety–related documentation you hold so it can be provided quickly once the buyer's solicitor raises enquiries. Typical documents to look for include:

A well-prepared property certificate pack that includes these documents reduces the number of additional enquiries raised during conveyancing and speeds up the transaction. It also signals to the buyer that the property has been properly maintained and any works were carried out with appropriate oversight.

Completing the TA6 form

The TA6 Property Information Form includes a section on building works and alterations (Section 11 in the current 4th edition). You will be asked whether any alterations or additions have been made to the property and whether Building Regulations consent was obtained. You should answer accurately and attach any relevant completion certificates or consents.

If you know that works were done but do not have the Completion Certificate, you should disclose this clearly rather than leaving the question unanswered or answering that you are unaware. Misrepresentation on the TA6 form can give a buyer grounds for a claim after completion. The buyer's solicitor will carry out a local authority search that may reveal whether an application was made and whether it was completed, so incomplete disclosure is unlikely to remain hidden.

Where the Completion Certificate cannot be located, your options are typically:

1. Retrospective regularisation. Apply to the local authority for a regularisation certificate confirming the works meet current regulations. This involves an inspection and may require opening up some elements of the construction. The authority charges a fee, and timescales vary.
2. Indemnity insurance. An indemnity policy can be obtained to protect against the risk of enforcement action by the local authority for the absence of approval. This is a common practical solution where the works are old and the chance of enforcement is low, but it does not actually confirm whether the works were done to the required standard. See our broader guide on missing Building Regulations sign-off for detail on both options.

Fire safety costs to be aware of when selling

Depending on what your sale preparation reveals, there may be costs associated with fire safety compliance. Common items include:

These costs are generally modest compared to the overall cost of selling a property, but they can cause delays if not identified and addressed early. For a broader overview of the costs involved in selling, see our guide on the hidden costs of selling a house.

Practical steps for sellers

To avoid fire safety documentation causing delays once your sale is under way, work through the following checklist before listing:

1. Identify all works that required Building Regulations approval. This includes extensions, loft conversions, garage conversions, structural alterations, and notifiable electrical or plumbing work. For each, check whether you hold a Completion Certificate.
2. Contact your local authority Building Control department if you cannot find the certificate. They should hold records of applications and inspections. Ask for a copy of any completion notices issued.
3. If your property was previously rented, locate any fire risk assessments, HMO licence documentation, and smoke alarm installation records.
4. If you are in Scotland, confirm that interlinked alarms are in place and functioning before listing.
5. Check smoke and carbon monoxide alarms throughout the property are working. Replace batteries or units as needed.
6. Instruct your solicitor to carry out a local authority search before listing if you are uncertain about what applications and approvals are on record. This allows you to address gaps proactively rather than reactively.
