About Us & What We Do
At The Cat Flap Co., we believe pets deserve freedom — and owners deserve peace of mind.
We’re a small, family-run business providing expert cat flap and pet door installations across London, Kent, Essex, and the South East.
We’ve worked in everything from city flats to countryside cottages — always with a friendly, tidy, and pet-first approach.
What We Do
We specialise in:
• Installing cat flaps into double-glazed glass (custom-made sealed units)
• Fitting flaps into brick walls and insulation
• Installing in uPVC doors, wooden doors, and patio glass
• Offering clean, secure installs by professional fitters
• Providing free advice on flap types and sizing
We’re also qualified glaziers, so we can quote for:
• Window and door replacements
• Custom glass panels for flaps
• Additional glazing work at the same time as your flap fitting
