External Wall Insulation (EWI) is two jobs in one — a thick insulation layer fixed to your outside walls, finished with a through-coloured render. For solid-wall properties in Batley, it's the single biggest upgrade you can make.
Why EWI in Batley?
No loss of internal floor space, unlike internal wall insulation.
Local context: Batley, West Yorkshire
Mill-town terraces in the centre and large 1950s estates around the edges; many properties are prime EWI candidates. Damp valley microclimate makes vapour-open silicone the right call on older walls. We cover the full West Yorkshire area from WF17 outwards, including Birstall, Heckmondwike, Liversedge, Gomersal, Cleckheaton and the wider postcodes (WF17). Most Batley jobs are surveyed within 48 hours — we know the streets, parking constraints around landmarks like Batley Town Hall, and the typical substrates we'll find on the wall.
Benefits
- No loss of internal floor space.
- Refurbishes tired solid-wall properties to modern standards.
- Long-life system when detailed properly.
- Major reduction in heating bills.
- Eliminates cold bridging and most internal condensation.
- Brand-new render façade included.
Local considerations
- Reveals, sills and drip beads are where EWI fails. We detail these properly; many cheap installers don't.
- Plan for moved rainwater goods, soil stacks and meter boxes — the project is more than just 'boards and render'.
- EWI on a damp wall just traps the damp. Cure the damp problem first.
- EWI changes the external footprint of the building by 100–200mm — windows, sills, rainwater goods and roof overhang all need designing in.
- Get the breathability right — for older solid-wall properties in Batley, mineral wool with a silicone topcoat is usually safer than EPS.
Our process in Batley
- Survey + thermal performance calc.
- Scaffold + access design (especially important on tight {town} streets).
- Substrate prep — make good, reposition rainwater goods.
- Fix EWI boards; cut around openings; detail reveals.
- Mesh-reinforced base coat.
- Through-coloured silicone TC topcoat.
- Final inspection + handover paperwork.

Frequently asked questions
Do you cover Birstall, Heckmondwike, Liversedge, Gomersal?
Yes — we install EWI across Batley and the surrounding areas.
Will EWI affect my windows?
Window reveals will need re-detailing. We design new reveal beads and trims into the quote — it's not a hidden extra.
Are there grants available?
Grant schemes change. Ask on enquiry — if there's an active scheme that fits your Batley property, we'll point you to it.
How much can EWI save on bills in Batley?
Typically 25–35% off heating demand for solid-wall properties. The exact figure depends on current insulation, heating system, and how the house is used.
What thickness of insulation do you use?
Most Batley projects sit between 90mm and 150mm, depending on the U-value target and existing detailing. We size it on survey.
Does EWI need planning permission in Batley?
Usually no for like-for-like exteriors on standard housing, but conservation areas and listed properties need checking. We'll advise on survey.
Book a free on-site survey. We'll inspect the substrate, identify failures and recommend the right system.
We design EWI from the substrate up — board type, fixings, mesh, beads, finish — to match your specific Batley property. No off-the-shelf specs.
