In short
- Published 2026 UK ranges per m², supplied and applied: sand and cement £40–£80, monocouche £55–£90, silicone thin-coat £60–£120, EWI £90–£150 or more.
- London and the South East typically price 15–25% above national averages, so Guildford quotes tend to sit in the upper half of each range.

Why Surrey sits toward the top
Labour rates across London and the South East are higher than the UK average, commonly by 15 to 25 per cent. Surrey homes also tend to be larger, with more bays and detail, and a higher proportion are in conservation areas or near trees, which adds complexity.
Whole-house examples
Net wall area is the external wall area minus large openings such as windows and doors. Typical net areas and 2026 ranges including scaffolding:

Measure your own house for a better estimate: the length of each wall multiplied by its height, minus windows and doors.
The extras that change a quote
- Scaffolding: £800 to £2,500 for a typical two-storey house, more for complex or tall buildings. See scaffolding for rendering.
- Removing old render or pebbledash: around £10 per m² plus skips at £125 to £320 a week. See rendering over pebbledash.
- Substrate repairs: brick replacement, lintels, crack stitching.
- Sill extensions, bead upgrades and moving services such as meters, pipes and satellite dishes.
- Building control fees where the work counts as a thermal element renovation. See Building Regulations for rendering.
- Planning fees where consent is needed.
What reduces cost without cutting corners
- Rendering over sound existing render or pebbledash instead of stripping.
- Doing the whole house in one programme rather than elevation by elevation.
- Choosing a mid-tone colour, which is quicker to finish evenly than very dark shades.
- Booking between late spring and early autumn, when weather delays are fewer.

Questions people ask
How much does it cost to render a three-bed semi in Guildford?
Commonly £7,000 to £11,000 in silicone including scaffolding, or £6,500 to £10,000 in monocouche, depending on preparation and detail.
Is silicone render worth the extra cost?
For most homeowners, yes, because it needs no painting and resists dirt and algae better. Over 20 years it often costs less than a painted render. See silicone vs monocouche.
