How this calculator works
- Rates are typical 2026 UK supply-and-fit quotes: sand and cement £40–60 per m2, monocouche £45–70, silicone thin-coat £50–80. Market rates, not regulated prices: region, substrate condition and finish move them.
- House-type areas are typical net render areas (mid-terrace about 60 m2 because side walls are shared, bungalow 90, semi 110, detached 160). Measure yours for a tighter figure: wall length times height, minus large openings.
- Scaffold adds £600–£1,000, the typical 2026 cost for a two-storey house rendering job.
- Excluded: removing old or failed render (typically £20–40 per m2 on 2026 quotes), substrate repairs, and external wall insulation. Insulated render (EWI) is a different job entirely, typically £90–150 per m2 in 2026, see the render types guide.
- Re-rendering more than 50% of an individual wall's surface area counts as renovating a thermal element. Regulation 23 of the Building Regulations 2010 then requires the whole element to meet the Part L standard.
- That applies in so far as it is technically, functionally and economically feasible (guidance in Approved Document L). Budget for that conversation before stripping a solid wall.
- These are typical quote ranges, not a quotation. Renderers price on a look at the walls, always.
The worked numbers, 110 m2 of wall
| System | Render (110 m2) | Scaffold | Typical total |
|---|---|---|---|
| Sand and cement | £4,400–£6,600 | £600–£1,000 | £5,000–£7,600 |
| Monocouche | £4,950–£7,700 | £600–£1,000 | £5,550–£8,700 |
| Silicone thin-coat | £5,500–£8,800 | £600–£1,000 | £6,100–£9,800 |
What moves the price
- Stripping the old render: if the existing coat is failed or hollow it must come off first, typically £20–40 per m2 on 2026 quotes, before the new system goes on (see what re-rendering costs).
- Substrate condition: blown brickwork, repointing or crack stitching are priced on inspection, no calculator sees them from the kerb.
- Detailing: bay windows, bands, bell casts and stop beads add labour; plain elevations price at the bottom of the range.
- Region: London and the South East commonly quote above these typical ranges.
How long the job takes
A straightforward semi typically runs one to two weeks on site: scaffold up, preparation and beading, base and top coats with curing time between, scaffold down. Weather stretches it, renders have minimum temperatures and monocouche in particular dislikes rain on fresh work, so autumn and winter jobs carry more programme risk.
Your semi is not exactly 110 m2. Measure the walls, knock off the glazing, and put the real area into the calculator.
