The short answer
Get at least three quotes from manufacturer-approved or trade-accredited rendering specialists, all on the same specification, and insist on an itemised written quote after an on-site survey rather than a phone-only price. Tell each specialist the same brief — the wall area and substrate, the render system you want, the colour and finish, and any access issues — so the quotes are comparable. Then line them up item by item and weigh price alongside the guarantee, survey quality and reviews. See how to choose a renderer for the checks that matter.
Getting quotes is the step where homeowners most often end up comparing apples with pears — one quote includes surface repairs or scaffolding, another leaves them out; one specifies a premium silicone system, another a basic cement render. This guide explains what to tell renderers, what a good quote should contain, and how to compare three quotes fairly. We are an independent information and introduction service: we do not render houses, and we publish this guidance free.
Getting quotes at a glance
- How many At least three
- Same brief Identical spec to each
- Survey On-site, not phone-only
- Format Itemised, in writing
- Accreditation Manufacturer or trade scheme
- Compare on Like-for-like spec
What to tell each renderer
To get comparable quotes, give every specialist the same brief. The more precise you are, the less room there is for quotes to drift apart on hidden differences. Cover the wall area and how much of the house is being rendered, the existing finish and wall type, the render system you want, the colour and texture, and any access issues such as upper floors needing scaffolding. Ask each to survey the property in person rather than quote over the phone, because a measured survey is what makes a quote reliable.
| Tell the renderer | Why it matters |
|---|---|
| Wall area & scope | The core of the quote — must match across all three |
| Existing finish & wall type | Solid vs cavity, and any repairs, change the price and system |
| Render system | Sand-and-cement, monocouche, silicone or lime changes cost |
| Colour & finish | Non-standard colours and textures can add cost and lead time |
| Access | Upper-floor scaffolding and awkward access affect price |
What a good written quote includes
A quote you can rely on is itemised and in writing, not a single headline figure. It should set out the area and elevations covered, the render system and colour, surface preparation and any repairs, scaffolding, the number of coats, making good, waste removal, the guarantee length and terms, and the deposit and payment schedule. If a quote is vague about any of these, ask for it to be spelled out before you compare.
How to compare quotes fairly
With three written quotes on the same brief, line them up item by item. A price gap often comes down to one quote including surface repairs, scaffolding or a premium render system that another omitted — adjust for anything missing before judging on price. Sense-check the figures against typical costs in our rendering cost guide, then weigh the things price alone does not capture: the quality of the survey, the clarity of the guarantee, independent reviews and how the specialist communicated. The cheapest quote is not automatically the best value, and the most expensive is not automatically the safest. These are general pointers, not advice for your specific job.

Frequently asked questions
How many rendering quotes should I get?
At least three, all on the same specification — same wall area and scope, the same render system, colour and finish. This lets you compare fairly and spot a quote that is cheap only because it leaves something out, such as surface repairs or scaffolding.
Should I get a survey or a phone quote?
Insist on an on-site survey. A measured survey is what makes a quote reliable; a phone-only or online estimate can change significantly once a specialist sees the walls, the condition of the existing finish, the access and any repairs needed. A proper survey also lets you judge how the renderer works.
What should a rendering quote include?
An itemised written quote should list the area and elevations, the render system and colour, surface preparation and repairs, scaffolding, the number of coats, making good and waste removal, the guarantee terms, and the deposit and payment schedule. Ask for anything vague to be spelled out.
Is the cheapest rendering quote the best?
Not necessarily. A lower price can mean a basic render system, omitted surface repairs or scaffolding, or a shorter guarantee. Compare on a like-for-like specification and weigh the guarantee, survey quality and reviews, not just the headline figure.
