Bespoke Radiators: What “Made to Measure” Actually Means (Sizes, Lead Times, Pricing)

Finding the right radiator isn't always as simple as choosing a standard size.
You may have an awkward alcove, a chimney breast, a narrow wall or existing pipework that you don't want to move. Sometimes the radiator you like is available in the wrong width, while another option fits the space but doesn't provide the heat output you need.
This is where bespoke radiators can be worth considering.
A made-to-measure radiator gives you more flexibility over the size and specification, helping you find an option that works with the space you actually have.
But what does "made to measure" really mean? How are bespoke radiators sized, how long do they take to arrive, and how much do they cost?
Here's what to know before ordering.
What is a made-to-measure radiator?
A made-to-measure radiator is produced to a specified size rather than being selected from a fixed range of standard dimensions.
The exact level of customisation depends on the manufacturer and radiator range. Some made-to-order radiators allow you to choose a particular width, height, column configuration and finish within the manufacturer's available specifications.
This can be particularly useful when a standard radiator doesn't quite work for your room.
For example, the DRS bespoke radiator collection includes made-to-measure column radiators in different sizes and configurations.
It's important to remember that "bespoke" doesn't necessarily mean that every dimension or feature can be changed. Each manufacturer has its own production limits, available finishes, and sizing options.
When might you need a bespoke radiator?
If a standard radiator fits your wall and provides enough heat, there’s usually little reason to make the job more complicated.
A bespoke radiator becomes more useful when the space has specific requirements.
You might consider one if you have:
- An unusually narrow or wide wall
- A chimney breast or alcove
- A period property with awkward dimensions
- Large windows and limited wall space
- Existing pipework that you want to keep in place
- A particular design in mind that isn’t available in a standard size
- A renovation where the radiator needs to fit precisely into the finished space
For some projects, choosing a made-to-measure radiator can be easier than changing the wall, moving pipework, or compromising on the style you originally wanted.

What sizes are available?
One reason homeowners choose bespoke radiators is the greater flexibility in size and configuration.
Available sizes depend on the radiator and manufacturer. The DRS bespoke collection offers made-to-order radiators in 2, 3, 4, 5, and 6 columns.
When comparing sizes, don’t look at height and width alone. You should also check:
- Overall radiator depth
- Number of columns
- Heat output
- Pipe centres
- Wall-to-pipe measurements
- Connection positions
- Weight
- Available finish
- Lead time


How do you measure for a bespoke radiator?
Accurate measurements are particularly important when ordering a made-to-order radiator.
1. Measure the available width
Measure the usable width of the wall where the radiator will be installed.
2. Measure the available height
Check the distance from the floor to the maximum height available.
3. Check the pipe centres
If you’re replacing an existing radiator and want to keep the current pipework, measure the distance between the pipe connections.
This is one of the most important measurements to check before ordering.
4. Check the wall-to-pipe measurement
Measure how far the existing pipework sits from the wall.
A new radiator may have different dimensions, so don’t assume that the pipes will automatically line up.
5. Measure twice
It sounds obvious, but it’s worth doing.
Made-to-order products are manufactured for a particular specification, so you should be confident about your measurements before placing the order.
What size bespoke radiator do I need?
Getting a radiator to fit the wall is only part of the job.
You also need to make sure it can provide enough heat for the room.
Radiator heat output is commonly given in BTUs or watts. The amount of heat required depends on factors such as:
- Room dimensions
- Ceiling height
- Number of external walls
- Window size
- Insulation
- Property type
- Room usage
This means you shouldn’t choose a bespoke radiator based on its physical dimensions alone.
A radiator may fit perfectly into a narrow space but still not provide enough heat.
Our radiator BTU calculator can help you get an initial idea of the output required for your room.
For a more precise requirement, particularly during a heating installation or renovation, speak to a suitably qualified heating professional.


Do more columns mean more heat?
Not necessarily.
Column radiators are available with different numbers of columns, and increasing the number of columns can affect the radiator’s depth and heat output.
For example, a two-column radiator will generally have a shallower profile than a three- or four-column model of similar dimensions.
However, the actual heat output depends on the individual radiator’s size and specification.
So rather than assuming that more columns automatically means more heat, compare the manufacturer’s stated BTU or watt output.
If you’re looking for a traditional column style, you can also browse our column radiators before deciding whether you need a bespoke size.
How long do bespoke radiators take?
This is an important difference between a standard radiator and a made-to-order model.
A standard radiator may be available for relatively quick delivery, while a bespoke radiator has to go through the manufacturing process after the order is placed.
Because bespoke radiators are made to order, lead times are generally longer than for standard stock radiators. The exact timeframe can vary depending on the size, colour and specification, so always check the current lead time before ordering.
If you’re replacing a radiator during a wider refurbishment, don’t leave the order until the last minute.
How much do bespoke radiators cost?
There isn’t one standard price for a bespoke radiator.
The final cost depends on the specification you choose.
Factors that can affect the price include:
- Radiator size
- Number of columns
- Heat output
- Finish or colour
- Radiator design
- Delivery
- Any additional accessories
Larger radiators, additional columns and specialist finishes can all increase the overall cost.
For this reason, it’s better to compare the price of radiators with similar dimensions, heat output and specification rather than comparing starting prices alone.
You can view the current DRS bespoke radiator range for available models and pricing.
Can a bespoke radiator work with existing pipework?
It can, but you need to check the measurements first.
If you’re replacing an existing radiator, take measurements of the current pipe centres and connection positions before choosing the new radiator.
This is particularly important if you’re changing the height or width of the radiator.
A radiator that looks like the right size may still require pipework alterations if the connections don’t line up.
If keeping your existing pipework is important, provide the measurements when discussing your radiator requirements.

What about radiator weight?
A larger bespoke radiator can be considerably heavier than a small standard radiator.
The wall therefore needs to be capable of supporting the radiator securely.
This is particularly important with plasterboard or stud walls.
Before installation, check the wall construction and use suitable fixings and brackets for the radiator and wall type. If you’re unsure, ask a qualified heating professional to assess the installation requirements.
The radiator will also contain water once the heating system is filled, so the installed load will be greater than the radiator’s empty weight.
Are bespoke radiators available in different colours?
Colour options depend on the particular manufacturer and radiator range.
The DRS bespoke collection includes White and RAL colour options on its made-to-order radiators, giving you more choice when matching a radiator to your interior scheme.
If you have a particular RAL colour in mind, check its availability for the exact radiator you’re considering before ordering.
This is especially important because colour and finish can affect both price and lead time.

What is a RAL colour?
RAL is a standardised colour-matching system that uses reference numbers to identify specific colours.
For a bespoke radiator, a RAL reference allows you to specify a particular shade rather than relying only on a colour name.
The DRS made-to-order column radiator range offers RAL Classic colour options, alongside selected special finishes.
How does a RAL colour chart work?
A RAL colour chart shows colours alongside their RAL reference numbers. It helps you choose a specific shade and compare it with other colours in your room.
You can view the DRS RAL colour chart to explore the available options.
Before ordering, check that your chosen colour is available for the specific radiator. Colours can also appear differently on a screen, so consider checking a physical RAL chart or sample if an exact match is important.
Bespoke vs standard radiators: which is right for your space?
It comes down to the space, heat requirement and design you need.
A standard radiator may be the simplest option if you can find one with the right dimensions and heat output.
A bespoke radiator may be more suitable when:
- Standard sizes don’t fit the available space
- You need a particular width or height
- You want a specific column configuration
- Existing pipework limits your options
- You have an unusual wall space
- The radiator forms an important part of the room design
It’s also worth looking at vertical radiators if your wall is narrow but you have more height available.
In some rooms, a vertical radiator can solve the space problem without needing a completely bespoke radiator.
Common questions about bespoke radiators
Are bespoke radiators made to any size?
Not necessarily. Made-to-measure radiators are produced within the manufacturer’s available sizing and production specifications. Always check the available dimensions for the specific model.
How long do made-to-measure radiators take?
Because made-to-measure radiators are produced to order, they can take longer to arrive than standard radiators held in stock.
The lead time can vary depending on the size, design, colour and specification you choose. Always check the current estimated lead time before ordering, particularly if you’re working to a renovation or installation deadline.
Are bespoke radiators more expensive than standard radiators?
They can be, as they are made to order rather than produced as a standard stock size. The price depends on the size, column configuration, finish and specification.
Can I choose the colour of a bespoke radiator?
Yes, depending on the radiator and manufacturer. The DRS made-to-order column radiator range offers RAL Classic colour options alongside selected special finishes.
Where can I find a RAL colour chart?
You can view the available RAL colour options through the DRS RAL colour guide. If an exact colour match is important, check a physical colour chart or sample before ordering.
Can I use a bespoke radiator with my existing central heating system?
A made-to-order radiator can be suitable for an existing central heating system, but the radiator’s heat output, connections and dimensions need to be checked before ordering.
Can I keep my existing radiator pipework?
Possibly, but the pipe centres and connection positions need to be checked against the new radiator. If they don’t match, some pipework adjustment may be required.
Can I keep my existing radiator pipework?
Possibly, but the pipe centres and connection positions need to be checked against the new radiator. If they don’t match, some pipework adjustment may be required.
Are bespoke column radiators available?
Yes. The DRS bespoke collection includes made-to-order column radiators in 2, 3, 4, 5 and 6 column configurations.
What should I measure before ordering?
Measure the available height and width, pipe centres, wall-to-pipe distance and the surrounding space. Also check the required heat output and radiator depth.
Can I order a bespoke radiator for a narrow space?
Yes, depending on the available sizing options. Made-to-measure radiators can be useful where a standard radiator is too wide or doesn’t provide the right dimensions for the space.
Can bespoke radiators be returned?
Made-to-order products can have different cancellation and return terms from standard products because they are manufactured to a customer’s specification. Always check the applicable return terms before ordering.
Find the right bespoke radiator for your space.
A made-to-measure radiator can be a practical solution when a standard radiator doesn’t quite fit.
The most important things to get right are the dimensions, heat output, pipework, wall requirements, finish, price, and lead time.
If you already know the size and specification you need, you can explore the DRS bespoke radiator collection to see the available made-to-order options.
You can also use our radiator BTU calculator to get an initial idea of the heat output required for your room before choosing a radiator.
If you’re unsure about measurements, RAL colour options, or compatibility with your existing heating system, check the details before placing your order. Getting the specification right at the start can save time and avoid problems later.
