What changes the cost of rendering a house?
The cost of rendering a house depends on the type of render, the area of wall, whether old render has to come off, the repairs needed underneath and the scaffolding to reach it all safely. This page does not print a price, because we could not find two dated public sources that agree on one.
Last reviewed:What a rendering price covers
Render is a coating applied to the outside walls of a house to protect and finish them. A rendering job is more than the coat you see. A typical quote for a Cheshire house covers scaffolding, protecting windows and paths, preparing the walls, any removal of old render, fixing beads at corners and edges, applying the base and finish coats, and cleaning up.
QuoteZila is starting in Cheshire, with Crewe, Nantwich and Sandbach among the first towns, and anyone in the UK can post a job. We have not put a price on this page. We could not find two dated public sources that agree on what rendering costs, so the guide focuses on what changes the total and what each quote should say.
The main types of render
Renderers use several systems, and the name on the quote matters:
- Sand and cement render. A traditional mix applied in coats and usually painted. It is widely used on modern masonry.
- Lime render. A traditional render for older solid walls. It is softer and more flexible than cement render, and is the traditional finish on many older buildings.
- Monocouche render. A through-coloured, one-coat render applied thicker in a single pass and scraped to a textured finish. It does not usually need painting.
- Thin-coat renders. Silicone, acrylic and mineral renders applied as a thin finish over a prepared base coat, often in a wide range of colours.
- Pebble dash and roughcast. Textured finishes with stones thrown or mixed into the final coat.
- Insulated render systems. Insulation boards fixed to the wall and finished with a render, which is a larger job that changes the thickness of the wall.
Ask each renderer to name the system, the maker and the number of coats. Two quotes for "render" can be for very different products.
What changes a rendering quote
| What changes | Why it matters | What to ask |
|---|---|---|
| Render type | Systems differ in materials, number of coats and labour | Which system and maker, and how many coats? |
| Wall area | More wall means more material and time | Which walls are included, and what area? |
| Old render | Hacking off old render is heavy, dusty work | Does the old render come off, and is disposal included? |
| Wall repairs | Cracks, loose brick or failed pointing need fixing first | What repairs have you allowed for, and what if more is found? |
| Scaffolding | Rendering whole elevations needs safe access | Is scaffolding included, and for how long? |
| Beads and details | Corners, window reveals and the base of the wall need beads and care | Are beads, sills and reveals included? |
| Finish and colour | Some renders need painting, others are through-coloured | Is painting included, or is the colour in the render? |
| Weather | Render cannot be applied in some conditions | What happens if weather delays the job? |
| Planning and building regulations | A change of look or a large re-render can bring rules into play [S1] [S2] [S3] | Have you checked whether permission or approval is needed? |
| VAT | Some renderers are VAT registered [S6] | Does the total include VAT? |
If one quote is much lower, look first at the render type, whether the old render comes off and whether scaffolding is included. Those three lines explain most gaps.
Planning permission
For most houses outside protected areas, rendering can be done without a planning application if the result looks similar. The Planning Portal says cladding or rendering the outside of a house may fall within permitted development, provided the materials are of a similar appearance to the existing house [S1]. It says that in a conservation area, a national park, an area of outstanding natural beauty or the Broads, you need permission before cladding with stone, artificial stone, pebble dash, render, timber, plastic or tiles [S1]. Listed buildings need listed building consent for significant works inside or out [S1].
The Planning Portal's answer on rendering adds a useful point [S2]. Replacing existing render with a similar-looking finish is usually permitted development, but changing the type or colour of render is likely to change the appearance enough to need permission.
Rendering over bare brick for the first time changes how a house looks, so check with the council before you commit.
Building regulations and insulation
Re-rendering is not only a planning question. The Planning Portal says that if you want to re-render external walls, building regulations may apply depending on the extent of the work [S7]. Where 25 per cent or more of an external wall is re-rendered, the regulations would normally apply and the thermal insulation would normally have to be improved [S7]. Wigan Council's building control guidance lists rendering or re-rendering more than 50% of an external wall's area as an example of renovation work [S3].
Ask your renderer whether they have checked that extent, and ask building control if you are unsure. If insulation is needed, an insulated render system or other work may be suggested, and that changes the price a great deal.
GOV.UK: find your local council for building control. QuoteZila is not affiliated with this organisation.
Older houses and solid walls
Many older houses were built with solid walls and lime mortar. They handle moisture differently from modern cavity walls.
A Northern Ireland government technical note on historic external wall finishes says pure sand and cement mixes are rarely acceptable on historic buildings because they trap moisture behind them and contribute to long-term problems [S4]. It says mixes based on lime rather than Portland cement are closer to the character of old work and more flexible [S4].
If your house is older, has solid walls, or is listed, ask for advice before choosing a render. A renderer who works with lime can explain the options. This is about the building, not a matter of taste.
Scaffolding and working at height
Most rendering jobs need scaffolding, because the renderer has to reach every part of the wall, often up to the eaves and gables, and work steadily across it. The scaffold may be part of the renderer's quote or a separate contract with a scaffolding firm.
This page gives no steps for working at height. Ask:
- Is scaffolding included, and who erects and inspects it?
- How long will it stay up, and is there a cost if the job overruns?
- Will it block a drive, a path or a neighbour's access?
- Who protects windows, doors and plants?
HSE: work at height. QuoteZila is not affiliated with this organisation.
You can read HSE's guidance on work at height for what businesses doing this work must plan for.
Living with a new render
New render needs a little care in its first months and some upkeep after that. Ask the renderer:
- How long the render needs before it can be painted, if it is a painted system.
- How to clean it, and whether pressure washing is allowed.
- What to do about hairline cracks, and when they need attention.
- Whether gutters, downpipes and overflows should be checked, because water running down a wall can stain or damage any finish.
Keep the system name, the maker and the colour reference with your house papers. They make repairs and later work much easier to match.
How to compare rendering quotes
Citizens Advice says a quote is a fixed price, while an estimate is only a guess [S5]. It suggests getting written quotes from more than one trader and asking to see their insurance [S5]. For rendering, ask each quote to state:
- Which walls are included, and the area.
- The render system, the maker, the number of coats and the finish.
- Whether old render comes off, and how waste is removed.
- The repairs allowed for, and how extra repairs will be priced.
- Beads, reveals, sills and the detail at the base of the wall.
- Scaffolding, who provides it and for how long.
- Painting, if the render needs it.
- Any written warranty and what it covers.
- Whether VAT is included. A business must register for VAT when taxable turnover goes over £90,000 [S6].
Agree in writing how any extra work found once the old render is off will be priced.
Jobs you might post
These are examples, not taken from real job posts.
- "Semi-detached house, front and side walls. Old cement render is cracked and blowing. Want it removed and re-rendered."
- "Bare brick extension on the back of the house. Would like it rendered to match the existing rendered walls."
- "Older solid-walled cottage. Looking for advice on lime render for one gable wall."
Say which walls, the type of house, whether there is old render, whether you want a particular colour or finish, and anything that affects scaffolding, such as a conservatory or a shared drive.

Questions about rendering prices
How much does it cost to render a house?
This page does not print a figure. The render type, the wall area, removing any old render, repairs to the wall underneath, scaffolding and the finish all change the total. Ask for itemised written quotes for the same walls and the same render system.
Do I need planning permission to render my house?
Often not, if the new finish looks similar to what is there. The Planning Portal says you need permission before rendering or cladding in a conservation area, national park, area of outstanding natural beauty or the Broads, and that listed buildings need listed building consent. Ask the council if unsure.
Can I change the colour of my render without permission?
The Planning Portal says replacing render with a similar-looking finish is usually permitted development, but changing the type or colour of the render is likely to alter the appearance enough to need permission. Check with your council before choosing a very different colour.
Does re-rendering need building regulations approval?
It can. The Planning Portal says that if you want to re-render external walls, building regulations may apply depending on the extent of the work. Wigan Council's building control guidance lists re-rendering more than 50% of an external wall's area as an example of renovation work it controls. Ask your builder or building control.
Is cement render right for an old house?
Not always. A Northern Ireland government technical note says pure sand and cement mixes are rarely acceptable on historic buildings because they trap moisture behind them, and that lime-based mixes are more flexible. For an older solid-walled or listed house, ask for advice before choosing the render.
Why is scaffolding part of the price?
Rendering covers whole walls, often up to the eaves, so the renderer needs a safe working platform. This page gives no steps for working at height. Ask whether scaffolding is included, who erects it, and how long it will stay up.
Does QuoteZila check the businesses?
No. We don't check insurance, qualifications or registrations, so please check these yourself before you hire. You can report a quote or a business from your job page.
This page is general information, not professional or legal advice. QuoteZila does not check Gas Safe, WaterSafe, NFRC, NICEIC or other registrations against the register on your behalf: look them up yourself.
