We recently updated our price guide for internal wall plastering (you can find that price here) so we thought it would a good time to take another look at external wall rendering.
What is Wall Rendering?
Wall render was traditionally a mixture of sand, cement and other aggregates which are then applied to external walls in layers to form a protective coat that is an alternative to brickwork or cladding. While the cost of sand and cement is fairly cheap, the work needs to carried out by specialists and a scaffold is almost always required.
Also, there are other, more modern options such as silicone and acrylic render systems, these have their own pros and cons. But, how much does wall rendering typically cost in the UK?
We created this page as a guide so you can get a rough idea of how much wall rendering will cost you. Obviously, no two projects are the same and things like location, the age of the property and the amount of scaffold required will determine the price.
Also, make sure you read our section titled “Additional Costs” as there are some hidden costs that you may need to account for if you want to meet the current building regulations.
Do you live in an older property constructed prior to 1920? There is a good chance that your home is constructed with lime rather than cement. For older homes, you’ll need to get a price from a specialist renderer who understands the importance of breathability. Lime based render allows moisture to escape and prevents condensation but it also costs more than traditional cement.
Don’t Confuse Render With Plaster
Render is almost always applied outdoors, plaster is a different material and is used indoors.

Three Different Types of Render to Consider
There are three different types of render you can use on your external walls, each is priced differently;
- Sand and Cement – this is the traditional method of applying two layers of a sand and cement mixture to the walls. Once dry, the wall is usually painted with two or three coats of a good quality masonry paint.
- Monocouche – this is a cement-based product that has a coloured pigment added to the mixture. One finishing layer is installed on top of a base layer, you don’t need to paint the surface.
- Silicone – this is the most expensive type of render but has many benefits, it’s flexible so shouldn’t crack and it’s also breathable so can help prevent wall condensation. Like the Moncouche, this is also a “through colour” so no painting is needed, just a wash every few years or so.
Below You’ll Find Two Render Prices For Comparison
Below you will find two example wall rendering prices for your consideration, these were updated in 2021 and were sourced from a selection of wall renderers:
1) Rendering Price for a Small Terraced House Sand/Cement Finish
This price is for a sand and cement finish to a small terraced property. The existing render needs to be removed and disposed of, a sand and cement render is then applied in layers and allowed to dry. Finally, the dried wall is primed and then painted with two or if required, three coats of external wall paint.
For this estimate, we assume there are approximately 50 square metres of the wall to be rendered:
|Remove and dispose of existing render||£600.00|
|Apply layer of new S/C render inc primer, beads/trims etc||£2300.00|
|Paint, 2 to 3 coats||£600.00|

2) Cost to Render a Semi-Detached House With Coloured Silicone Finish
The price you can see displayed in the table below is for a typical semi-detached house with three sides. The existing wall render will be removed and two layers of render applied, the final layer being a silicone coloured product.
For this estimate, we assume that this semi-detached house has 100 square metres of external wall:
|Remove and dispose of existing render||£1000.00|
|Apply layers of new render with coloured silicone finish, inc primer, beads/trims etc as required||£6000.00|

Where Did These Render Prices Come From?
We contacted fourteen renderers from several places around the UK and asked them for prices. We also found over a dozen price lists from renderers published online.
Added Extras to Consider
Scaffolding costs can vary by a lot, it’s not just the height of the scaffold that needs to be considered but also its location. Erecting this access equipment over roads and footpaths is more expensive than on private land. Obstacles such as conservatories will also need to be bridged and this can add to the final price.
Insulation – if you intend to replace or install render to 50% or more of the walls on your house, the building regulations currently stipulate that must ensure that the wall insulation meets current requirements. If you have a cavity wall, this can be filled at extra cost or if you have a single skin wall, you can have an insulation board installed between the wall and the render. Cavity wall insulation is fairly cheap and easy to install but the insulation-backed render is very expensive, expect to pay north of £110 per square for the boards, render and all the necessary beads and trims. The reason it’s so expensive is that the wall will be around 100mm thicker so window sills need to be extended and other alterations made.
How Much Do Wall Render Repair Costs?
This depends on the type of render that is currently on the wall, as well as its condition. For Monocouche and silicone rendering, patch repairs are not advised, you would need to replace the whole wall, or at least apply an extra layer to the entire wall to ensure a consistent colour throughout. For traditional sand/cement render, you may be able to chisel off the damaged section, replace as required and then apply a coat of paint.
As a general rule of thumb, if the existing sand/cement render issue is due to an “event” such as a water leak that has blown the render off the wall, or perhaps damage caused by an impact, then a repair should be possible. If however, the render is in generally poor condition then patch repairs are usually a waste of time and it would be better to replace the whole wall.
Don’t forget; the cost of the wall rendering isn’t just the labour and materials but also arranging for the scaffold, skip hire, finishing off with paint etc. It can be a false economy to keep repairing an old wall in patches and in most cases, it’s best to just get the whole lot done.
Can I Claim the Cost of Wall Rendering on My Home Insurance?
If the render has failed due to wear and tear, age, lack of maintenance or negligence then your insurance will likely reject any claim.
You may be successful in making a claim for damage to the render from a leak, a healthy tree falling onto the wall, a new case of subsidence or any other unforeseeable incident.
We have a guide to mortar mixes that provides details of the ideal amount of sand, cement, lime and other additives that are mixed together to create render.
