The surveyor spent an hour walking us through the whole house, wrote a plan at the kitchen table, and the grant side of it was sorted by them, not by me. Five months in, the bills are down by almost exactly what they said.

About this service

ProPERLA, designed properly.

ProPERLA is a BBA-certified breathable thermal coating — originally German-engineered, now widely specified across the UK on solid-wall houses, rendered bungalows and coastal properties where driving rain is the main fabric threat. Applied in two to three coats by a trained crew, it reduces wall water absorption by up to 95%, lifts wall U-value by around 29%, and independently tests to resist moss, algae and salt-air corrosion for at least 15 years. OMEGA is a certified ProPERLA installer covering our full patch — and one of very few teams qualified to apply transparent ProPERLA, the version used on listed and character brickwork where planners will not accept a painted finish. When you need the performance of an external coating without changing how the house looks, transparent ProPERLA is the tool for the job.

What you get

BBA-certified breathable system — vapour-permeable, not a plastic seal that rots the wall behind it
Up to 95% reduction in wall water absorption — proven under driving-rain exposure zones 3 and 4
~29% improvement in wall U-value, independently tested — translates directly to lower heating demand
25-year written product guarantee from ProPERLA UK, plus 5-year OMEGA workmanship cover
Transparent ProPERLA available for listed buildings and period brickwork — conservation-officer-approved on multiple East of England projects

The OMEGA difference

Eight things we do that most properla installers don't.

Not brand chest-beating. Each of these is something you can phone up and check — written down on every quote, baked into every install.

Ask any OMEGA surveyor to walk through this list at your first visit — if we don't match every row, don't hire us.

Accreditations that matter

Not logos. The certifications properla actually needs.

Every one of these is checkable online. Every one changes something concrete about the job — the survey, the materials, the guarantees, the way the grants land.

ProPERLA certified installer
Approved applicator for ProPERLA thermal coatings
Only ProPERLA-trained crews can issue the 25-year written product guarantee — we're one of very few in the region.
BBA certified
British Board of Agrément product certification
Every insulation layer we install is named on the quote and BBA-certified — no unlisted substitutes.
TrustMark
The only endorsement scheme backed by the UK consumer body
Every install is lodged on the TrustMark register so your cover travels with the property.
PAS 2030
Install quality standard for retrofit measures
Our teams are certified to the installation standard that grant-funded work is audited against.

How it works

Four steps from survey to handover.

01
Survey and substrate prep plan
Our surveyor measures every elevation, assesses the substrate, identifies any cracks or blown render needing repair, and agrees the colour (standard) or the transparent specification. Written quote inside 48 hours.
02
Substrate preparation (where most installers cut corners)
Walls or roof are soft-washed with a biocide, render cracks are stitched and patched, and the surface dried to the manufacturer's moisture spec before coating. We don't skip any of it.
03
ProPERLA application
Spray or roller, two to three coats by a ProPERLA-trained crew, with manufacturer-specified recoat windows honoured between each pass. Typical 3-bed semi: 3–5 working days.
04
Sign-off and 25-year guarantee
ProPERLA UK issues a numbered 25-year product guarantee in your name. OMEGA adds a 5-year workmanship cover. Every elevation photographed inch by inch for the record, so the provenance is clear for any future survey or sale.

What most customers ask first

The honest worries about properla — named and handled.

Every homeowner brings two or three silent worries to the first survey. Here's what they are and how we handle them — no salesy dodges.

The worry
Isn't this just fancy paint?
How we handle it
No — ProPERLA is BBA-certified and independently tested to reduce wall water absorption by up to 95% and lift U-value by around 29%. Paint doesn't move those numbers. The 25-year written product guarantee is insurance-backed, not a marketing promise.
The worry
Can I use it on a listed building?
How we handle it
Yes — transparent ProPERLA preserves the original brick or stone finish while still delivering the water-repellent performance. We've secured conservation-officer approval on multiple East of England projects and know how to write the application.

Live · grant eligibility check

What grants are likely on your properla?

Type your postcode. We'll show which schemes are likely to apply for your property and this measure. The exact eligibility check happens on your free survey — this is the indicator that gets you 80% of the way there.

Heuristic indicator only — the survey is where actual eligibility is decided. Free, no obligation, takes 45 minutes.

Grants and funding

Funding you may be eligible for.

Eligibility changes often. Our surveyor checks every active scheme for your home as part of the free survey, and handles the paperwork end-to-end if you qualify.

ECO4 — external coating is a named measure under PAS2035 where IWI/EWI is not feasible
Great British Insulation Scheme (GBIS) — for solid-wall homes where ProPERLA is the pragmatic fabric-first measure
Listed-building funding — regional conservation grants sometimes cover part of a transparent ProPERLA application; we flag eligibility at survey

Common questions

ProPERLA — answered honestly.

Is ProPERLA the same as external wall insulation?

No — external wall insulation (EWI) bonds 90mm or more of insulation board to the wall then renders over it, whereas ProPERLA is a thin coating applied to the existing wall or render. ProPERLA delivers a smaller U-value improvement than EWI but at a fraction of the cost and — crucially — without changing the building line. That makes it the right answer for listed buildings, conservation areas and any property where you can't afford the visual change.

What is transparent ProPERLA?

A clear version of the coating developed for listed brickwork and stonework where the original finish must be preserved. It has the same water-repellent performance as the pigmented version but leaves the visual surface untouched. It is almost always the right answer for Georgian and Victorian face-brick properties where planners won't accept a painted finish.

How long does ProPERLA actually last?

The written product guarantee is 25 years, and independent durability testing puts the minimum functional life at around 15 years in driving-rain exposure zone 3 — so the guarantee is deliberately conservative for most UK sites. Beyond that, the coating tends to weather gracefully rather than fail suddenly. If you ever want to refresh it, the overcoat is a single-day job on a typical semi.

Can it be painted over in future?

Yes — ProPERLA can be overcoated with a breathable masonry paint at any point without affecting the guarantee. Non-breathable plastic coatings would void it, which is why we give you a one-page spec sheet on sign-off listing every compatible overcoat. No guesswork for the next decorator.

Do you do the roof version too?

Yes — ProPERLA Roof is the tile-and-slate formulation, applied over a cleaned and biocide-treated roof. We almost always run the roof clean and the coating as one mobilisation so you only pay for scaffold once — the bundled cost typically comes in 20–25% under two separate jobs.
