Loft Ladders, Loft Stairs and Loft Conversions: Understanding the Many Building Regulations

Loft LaddersJust do a quick internet search on building regulations in the UK and you will see a confusing myriad of UK local authority laws that govern the use and erection of loft ladders, loft stairs and loft conversions. For example, why must loft stairs conform to building regulations, while there is no such requirement for loft ladders? This is because local authorities see the installation of a stairway as the beginning of a process to use a loft as a living space, rather than storage space. In this case, the regulations are more stringent. Loft areas that are used for storage generally aren’t accessed often. This is different from accessing a loft that’s been converted into living space that people will need to access frequently, such as a sleeping or study area. With more frequent use comes a greater chance of an accident. So, the enhanced building regulations exist to prevent injuries and to ensure the conversion proceeds according to all relevant rules and standards.

Nowadays we seem to have more possessions than we could ever use. Even items that aren’t particularly useful have monetary or sentimental value that often prevents us from discarding or donating them to a charity shop. If you need to store such items in your loft for infrequent access, a loft ladder will be the lowest cost and lowest hassle solution.

A Few Details on Applicable Building Regulations

Escape or ‘egress’ during a fire is one concern many local authorities have regarding loft ladders and loft conversions. If the space is used as a bedroom, this becomes a prime consideration because a person can escape more quickly by way of stairs than a ladder. For this reason, any loft stairs you install come under the purview of your local authority. Some homeowners claim that installing stairs simply gives easier access to a loft that’s being used for storage, but once the stairs are there, most local authorities recognise the loft’s potential as a living space. Though this often is not directly stated, the fact is that a loft almost always transforms into a habitable area when stairs are installed, and the rules are there to prevent injury and misuse.

Undertaking a Conversion Project

Whilst it’s not strictly necessary, we do recommend that you obtain a copy of the rules that apply to your project and read them thoroughly. What you’ll discover is that the regulations are highly detailed. The regulations we’re discussing are those that apply in England, Wales and Northern Ireland. In Scotland, they’re different. So, what exactly are building regulations? Well, they set out the minimum standards that are allowed for construction and design. For loft conversions, there are five main categories. Structural stability, fire safety, ventilation, access method and insulation.

About Structural Stability

If you plan to use the loft for living space or to store particularly heavy items, it’s likely you’ll have to reinforce existing ceiling joists or install entirely new ones. You’ll also need to ensure that load-bearing walls are adequately strong to support any increased weight. The same is true of loft ladders. They must be substantial enough and conform to all regulations. Many homeowners opt to install steel beams designed to support the enhanced joists. Also, evaluate the roof to ensure whether or not it should be reinforced or altered to conform with the loft conversion’s design.

About Fire Safety

Fire regulations are the strict and rightly so. It’s imperative that any loft conversion fully conforms to all applicable fire and safety regulations, including those related to fire doors. The converted loft’s walls and floor must have the ability to resist fire for thirty minutes. If you’re using glass in the conversion, it must be fire-resistant as well. Be sure to provide a method of egress by way of a protected stairway. In the past, escape windows were considered adequate, but the regulations no longer allow them, except in very narrowly defined applications. You’ll also be required to install fire alarms that are operated by mains power.

About Ventilation

Be sure you understand the terms “rapid ventilation” and “background ventilation” when undertaking a loft conversion. To provide rapid ventilation, you’ll have to install a window with a size that equates to 1/20th of the loft’s floor area. If the converted space will become a bathroom, mechanical ventilation that extracts 15 litres per second is required. The roof must be ventilated to prevent moisture condensation, along with both the eaves and ridge. Finally, an airspace of 50mm minimum must be allowed between the roof and any insulation you might install.

About the Access Method

Many homeowners underestimate the cost of a loft conversion. So, when it comes to choosing an access method, they choose affordable loft ladders over staircases. Be aware that building regulations tend to be quite strict and detailed regarding loft access, but choosing a loft ladder over a staircase can save substantial sumsif you are just creating a storage area.

About Insulation

For a loft to provide truly useful space, it should be thoroughly insulated. In fact, the building regulations and relevant amendments require that the loft, along with any new internal walls, must be insulated.

Just a Few Examples of Building Regulations

The building regulations are highly detailed, so be sure you have a good understanding before beginning the conversion. Here are just a few examples of how you’ll have to conform.  Since 2005, domestic electrical work is controlled under Part P of the regulations.  Beams must not bear into chimneys or the party wall between chimneys. A party wall is a structure that is placed on the border between two properties. It’s important to be careful in these cases, since disputes with neighbours can arise due to the wall being a party feature. The only non-fireproof interior door that’s allowed in a loft conversion is the one that accesses a toilet or bathroom.

As you can see, choosing loft ladders is perhaps the easiest decision you’ll need to make to access your loft space safely and effectively.
