Typical round prices: GBP 10-15 for a terrace/semi, GBP 15-25 for a detached, more for conservatory roofs and hard access. Most rounds now use water-fed poles (pure water, no ladders, frames included): the streak-free result depends on letting it dry WITHOUT wiping. DIY at height is where the comparison stops being financial: ladders + windows is a classic A&E combination: poles or the pro for anything above ground floor.
What The Window Cleaner Cost Calculator Works Out
- Per year: price per visit multiplied by visits a year. Rounds charge GBP 10 to GBP 15 a visit for a terrace or semi and GBP 15 to GBP 25 for a detached house, six-weekly being the trade's standard rhythm, so the annual spend lands between GBP 80 and GBP 180.
- DIY comparison: how many skipped visits repay a GBP 60 to GBP 100 water-fed pole kit. The classic cycle is the purchased kit, two virtuous Saturdays and a quiet rejoining of the round.
- What sets the price: window count, access and frequency. The round's business model is many adjacent regulars served quickly, which is why one-off cleans cost multiples of the regular visit and a street that organises itself gets quoted kindly.
- Conservatory roof and extras (advanced): conservatory roofs, dormers and extensions are the surcharge lines, often GBP 5 to GBP 15 extra per visit; the card multiplies them through the year.
- Inside cleans (advanced): most rounds only do the outside. An inside clean once or twice a year typically costs GBP 20 to GBP 40 and is added to the full annual bill.
- Full annual bill (advanced): outsides, extras and insides together, the real figure to compare against doing it yourself.
- DIY cost in your time (advanced): minutes per clean x the same number of visits x what an hour of your weekend is worth. The recurring chore's true price is attention rather than money.
- DIY true annual cost (advanced): the kit spread over a three-year life plus your time, set against the full bill. Water-fed poles leave frames and sills clean and dry spot-free only if the glass is left wet and not wiped.
- Next year's bill (advanced): the full annual bill after a percentage price rise, since most rounds review prices every year or two and announce it with a note through the door.
