About The Stow
Original new-town neighbourhood centre. Many original 1960s flats with undersized gas supplies that we've upgraded over the years.
Predominantly 1950s–70s post-war housing with a mix of terraces, semis, and 60s-built flats. Pockets of older stock around Old Harlow.
- Original 1960s flats often have undersized gas supply pipes that limit modern combi performance
- Older Old Harlow properties frequently have low mains water pressure that affects combi choice
- Many 60s/70s back boilers still in service — our regular work involves removing these and reinstating fireplaces
