External Rendering Cost Per Square Metre: A Bristol Guide

Typical prices per square metre in 2026

Prices depend heavily on the type of render. Traditional sand and cement render is usually the cheapest to apply, but it needs painting afterwards and is more prone to cracking over time. Monocouche (a through-coloured, one-coat render) costs a little more but never needs painting. Thin-coat silicone systems sit at the top end because the materials cost more, but they are flexible, breathable and tend to stay cleaner for longer.

These figures assume straightforward walls in reasonable condition. They are a starting point for budgeting, not a fixed quote, because every property is different.

• Sand and cement render: roughly £40 to £60 per square metre, plus painting
• Monocouche render: roughly £45 to £70 per square metre
• Silicone thin-coat render: roughly £60 to £90 per square metre
• External wall insulation with render: often £100 to £160 per square metre

What that means for a whole house

A typical three-bed semi in Bristol has somewhere between 80 and 120 square metres of renderable wall area, so a full re-render commonly lands between £4,000 and £9,000 depending on the system. A small terraced house with only a front elevation to do might be £1,500 to £3,000, while a large detached property can go well beyond £10,000.

Scaffolding is a significant part of the bill and is sometimes quoted separately, so always check whether it is included. For a semi-detached house expect scaffolding to add roughly £800 to £1,500. Tight terraced streets, conservation areas and awkward rear access, all common in older Bristol neighbourhoods like Bedminster, Easton and Bishopston, can add to both scaffold and labour costs.

The factors that move the price most

Two identical-looking houses can get very different quotes, and the reasons are usually hidden in the walls. Removing old, failed render is slow, messy work and can add £10 to £20 per square metre before the new render even goes on. Blown or damp substrates may need repairs, and older solid-wall properties often benefit from a breathable system, which affects material choice.

Detail work matters too. Lots of windows, bays, decorative banding and stop beads all take time, so a fiddly elevation costs more per square metre than a big plain wall. Winter work can also cost more or take longer because most renders need mild, dry conditions to cure properly.

• Stripping old render versus rendering over sound existing walls
• Wall condition, damp issues and any repairs needed first
• Access, scaffolding requirements and parking or permit costs
• Number of windows, corners and decorative details
• Choice of render system and finish colour

How to compare quotes sensibly

The cheapest quote is rarely comparing like for like. Ask each builder to confirm in writing which render system and manufacturer they are using, whether old render removal and disposal is included, whether scaffolding is in the price, and what preparation work such as beading, mesh and primer is allowed for. A quote that skips preparation is where problems, and extra bills, tend to appear later.

It is also worth asking about guarantees. Reputable render manufacturers offer system warranties when their products are applied to specification, and a decent contractor should be happy to explain what cover applies to your job. Finally, get quotes from firms who have worked on similar properties locally, because Bristol's mix of Victorian solid-wall terraces and modern cavity-wall homes calls for different approaches.
