🔧 DIY Tips
Want to fit a letterbox lock yourself? Here's what to know:
- Measure first: Check your letterbox opening size - locks come in standard sizes but your opening might not match
- Door type matters: UPVC and composite doors have specific letterbox systems - you might need the exact replacement part
- Screw access: Some letterboxes screw from inside, others from outside - check before buying the lock
- Spring tension: Gravity flaps need correct spring tension - too tight and post won't go through, too loose and they don't seal
- Draught sealing: Brush seals wear out - replace the brush strip if it's thin or missing
Simple gravity flaps are easy DIY. Key-operated locks need more precision. If your door's UPVC or composite, getting the right part matters.
Rather leave it to a pro? No problem - that's what I'm here for. Give me a call.
Good to Know
Junk mail reduction: Gravity flaps and keyed locks stop people pushing leaflets through. You'll still get addressed post. Put a "No junk mail" sign up as well for best results.
Royal Mail delivery: Gravity flaps allow post delivery. Keyed locks mean you need to unlock daily or post can't be delivered. Internal cages let post in but lock it securely inside.
Security benefit: Letterbox locks prevent "fishing" attacks where criminals use tools to reach through and grab keys, unlock doors, or steal post from inside.
Draught reduction: Proper letterbox seals reduce heat loss and draughts. Brush seals work well but wear over time. Gravity flaps seal better but cost more.
Door compatibility: Most external doors can take letterbox locks. Measure your opening - standard UK size is 250-260mm wide, 40-45mm high. Odd sizes need custom solutions.
Key types: Some keyed letterboxes use standard keys, others use unique keys. Consider how many keys you need and whether you want all household members to have access.
Maintenance: Keep the mechanism clean - dust and debris stop smooth operation. Oil hinges annually. Replace brush seals when they look worn.
Fire safety: Some buildings require letterbox seals that automatically close in fire conditions. We'll advise if this applies to your property.
Alternative solutions: If you want to stop junk mail completely, an external post box removes the letterbox issue entirely. We can advise on options.

Letterbox lock fitting is £60 including labour. The lock itself costs £15-35 depending on type (simple gravity flap, key-operated lock, or combination lock). Total cost typically £75-95 fitted.
What types of letterbox locks are available?
