Cast Iron Radiators for Listed Buildings

If you live in a listed building, then modern cast iron radiators that feature period designs are the perfect way to keep your home efficiently heated all-year-round. However, before you move forward, there are some important pieces of information you need to know. Keep reading to find out more…

Permissions

The first thing you’ll want to do is ensure you have all of the permissions you require. 

These permissions vary depending on the exact nature of the work to be carried out as well as the features of interest that may be present in your listed building. 

The permissions you require can include: 

  • Listed building consent - your local authority Conservation Officer will be able to tell you whether you need to apply for listed building consent.
  • Planning permission - your local authority may require you to apply for planning permission if you intend to install cast iron radiators in your listed building.
  • Building regulations - all works carried out will need to be done in accordance with the Building Regulations, with the work subsequently inspected by the Building Control officer of your local authority. 

Note - unauthorised work on a listed building is a criminal offence. Not only are individuals liable to prosecution, but all work carried out may have to be reversed. If in doubt, always speak to your local authority first.

Things to consider when installing cast iron radiators in a listed building

Aside from securing the necessary permissions, there are a few other points to consider when buying and installing new cast iron radiators in a listed building. 

Structural survey

Before work begins, it is recommended that a structural survey of your listed building is carried out. 

A good structural survey will establish the routes that your central heating pipes take through the building, as well as highlighting any load bearing issues e.g. floors which may not be able to support the weight of a radiator.

Setting

One of the most important, yet arguably subjective, things to think about is the setting in which you are installing your radiators. 

According to Historic England, the national body that helps protect England’s heritage, cast iron sectional radiators should be set against brick or stone walls (or other patterned surfaces). 

Interestingly, Historic England suggests that ‘one piece cast replicas of the real cast iron sectional radiators’ should be avoided. They also recommend that owners of listed buildings should avoid plain faced steel radiators and other types of basic radiator too. 

Instead, Historic England states that owners of historic buildings should buy good quality, sectional cast iron radiators which are of the same or similar style to original period cast iron radiators. 

Note - Trads only supplies sectional cast iron radiators.

Historically-sensitive installation

Another important point to consider is the way in which the installation of your cast iron radiators is carried out. 

Guidance issued by Historic England states that:

‘Work should be carried out in such a way as to not damage or should minimise the loss of, and permanent scarring to, historic fabric (such as old walls, floors or ceilings). You should only carry out the minimum amount of work that involves disturbing existing historic fabric.

Where such work is needed, keep as much of the original fabric as possible and position any new or additional items discreetly where possible and where their function is not compromised’.

It’s important then, that you or the people you choose to carry out the installation, do so in a historically-sensitive way.

Where possible, installers should retain and even make use of existing features such as mouldings and skirting boards which can be used to mask or at least partially hide pipework. 

Installers should also avoid techniques such as destructive chasing and creating new openings and cuts into the fabric of the building. 

If this is unavoidable, then they should make cuts and chases which can accommodate more than just pipework alone and allow for other services to use them - thus reducing the total number of cuts into the fabric of the building during a renovation project.

Project planning

Are you intending to install cast iron radiators as part of a broader renovation project? 

Then it’s important to think about the stage of the project at which you’ll require your new radiators. You don’t necessarily want to receive them at the very beginning of the project, as you’ll have to find somewhere to store them until they are required.

Instead, consider making use of phased deliveries. 

Here at Trads we are able to offer phased deliveries, ensuring that your new radiators only arrive on site when you need them.

Picking the right cast iron radiator supplier for your listed building

In order to achieve the very best outcome to your home heating project in a listed building, you should work with a radiator supplier that has extensive experience supporting heritage projects.

A cast iron radiator supplier such as Trads understands the complexities that are sometimes associated with fitting new radiators into a listed building.

Plus, as mentioned above, Historic England advises that you should avoid cheap, one piece cast iron replicas, and instead choose sectional cast iron radiators that are faithful reproductions of period models

Below are just a few of the historic buildings to which Trads has supplied cast iron radiators. 

Concord House

The Lingholm Estate, Kewsick

Listed building cast iron radiators

Dating back to the 1870s, Lingholm on the Lingholm Estate, is a stunning Victorian mansion which is best known for being the place where Beatrix Potter spent many summers.

When the mansion was purchased by new owners in 2013, Trads was called upon to provide their expert advice. 

There followed a period of consultation, which entailed several onsite visits by the Trads team in order to establish specific requirements and to establish which radiators would be best suited to Lingholm’s Gothic Revival style.

The owners of Lingholm were delighted with the results, commenting on how wonderful it is to see the Estate keeping true to the character of the house, retaining the integrity of the property.
