Windows & Glazing
We look at every visible window on your elevation: era, style, condition, frame material and the era-appropriate detailing you currently have. Then we visualise three upgrade routes: a sympathetic refresh, a like-for-like modern replacement, and a heritage-grade rebuild. With the planning constraints for your Conservation Area or Article 4 direction (if any), and a budget that covers the whole house, not just the front.
- I'm refurbishing
- I want to drop the heating bills
- I want to sell soon and the windows are letting the house down

Visualised on your property
Sash, casement, anthracite or heritage; every window on your house, rethought with the planning rules.
You can hear the bus from the lounge. The original sashes rattle in February and the trickle vents whistle. A window company has quoted you £14,000 for white uPVC and you have a hunch your Conservation Area will refuse it. The Windows & Glazing report shows your house in three glazing directions, decodes the planning constraints on your specific street, and gives you a whole-house budget instead of a misleading three-windows quote.
What you actually get
Six concrete things inside the report.
Not a generic guide. These are the specific deliverables we ship for your address, every single time.
Three glazing options rendered onto your elevation
Refresh, modern replacement and heritage rebuild. Same brick, same surrounds, same view; just the frames and glazing redrawn so you can see the visual jump.
Planning constraints, decoded
Whether you are in a Conservation Area, under an Article 4 direction that removes PD on window changes, or in a listed building. The specific limits that decide if uPVC is even on the table.
Whole-house cost ladder
Costs per option for every window we can see, broken down by frame material and glazing spec. The number kitchen-table conversations actually need.
EPC and bills impact
How much each option moves your EPC band and what your typical annual heating saving looks like, calibrated to UK gas prices in the last 12 months.
Spec list you can hand a fitter
Frame material, profile, colour, U-value, locking, threshold detail and acoustic spec. One tight page a window company can quote against.
Built from this data
Grounded in the actual evidence of your property.
Every recommendation in the report ties back to one of these data streams. No generic Wikipedia summaries; no postcode averages.
Every visible window, decoded
Frame material, age, condition, profile depth, opening style and the giveaway clues to your existing U-value. Every elevation in the listing photos is read.
Conservation, Article 4 and listed flags
Pulled fresh for your address. The single biggest factor that decides whether a modern uPVC replacement is realistic or an automatic refusal.
Window-replacement applications near you
What your council has approved and refused on similar houses within a few streets. Particularly useful for spotting which frame colours and styles tend to land yes.
What it looks like
A glimpse of the report itself.
The full report lands as a single scrollable page. Visualisations sit alongside the costs, planning verdicts and value uplift, so you can argue with it (or with your partner) in one place.
Visualisation for this property
Victorian brick semi with slim-profile anthracite aluminium casement windows in original stone surrounds.
The verdict (one sentence)
Sash, casement, anthracite or heritage; every window on your house, rethought with the planning rules.
Cost ladder
Likely value uplift
Typically +£5k to +£15k
Cost & value
What it costs. What it adds.
Honest bands tuned to UK pricing in the last 12 months, plus a value uplift range for homes in your bracket.
Repair sashes, draught-strip, replace failed double-glazed units, paint and reseal. Same windows, much better performance.
Whole-house uPVC or composite replacement in a sympathetic colour, modern A-rated glazing, new sills where needed.
Slim-profile aluminium or timber sashes / casements in a heritage colour, restored stone surrounds, true-divided light where required by planning.
Bigger effect on listed and Conservation Area properties where heritage detail matters; smaller on 1980s estates where buyers expect modern uPVC and don't pay extra for timber.
The fine print, up front
What this report does not cover.
A clear list of what we leave out, so you never feel short-changed when you open it.
- Structural lintel work for new opening sizes (your fitter handles that scope)
- A guaranteed planning consent for non-PD changes (we report on the likely outcome based on recent decisions; the application is a separate exercise)
- Bay-window structural repairs where the bay itself has dropped (a different trade)
If we can't make this report outstanding for your address, you don't pay.
If we can't find the photos, planning history or constraints we need to make this specific report genuinely useful for your house, we refund the full price before generating a single word. Same goes if you read it and it just doesn't deliver.
