Overview
Cat flap fitting in Colindale NW9, explained

How it works
How cat flap fitting works in Colindale
Five steps, the same on every NW9 job, so you know what happens before you commit. Council and housing-association blocks built from precast concrete and dense block, as the Colindale stock goes, which is what a 80% flat share across the ONS neighbourhood covering Colindale actually produces is what we plan for here.
Step 1
Check the door or wall
Timber, uPVC, composite, glass or masonry — plus what is behind it. A cavity wall or a glazed panel changes the job completely.
Step 2
Set the height
Measured to your cat's chest height, so an older or arthritic cat still uses it in two years' time.
Step 3
Cut and line
Template marked, cut from both faces to avoid blow-out, and the edge lined, capped or sealed.
Step 4
Fit and seal
Flap fitted square, sealed against draughts and rain, and the fixings drawn up evenly so the frame does not bow.
Step 5
Set up and demo
Microchips registered, curfew set if you want one, and the flap left in training mode with the mess cleared.
Why choose us
Why Colindale customers book us
Four things decide whether a NW9 job goes well, and none of them are visible from a price list.
Booked around your day
Most cat flap bookings are within 48 hours and take a single short visit. Colindale (Northern) is the nearest station, so a NW9 visit rarely needs a whole morning set aside.
Colindale walls, not generic walls
We expect precast concrete panels and dense blockwork in Colindale, often with surface conduit — where 32% owner-occupation means the same home is booked again rather than a new tenant each year in NW9, and we carry the anchors, through-fixings and long bits that match. The mistake we spend most time undoing here is drilling blind into a panel with reinforcement or a buried cable behind it on these streets — measured on the walk in from Colindale (Northern) rather than assumed from a map.
Insured and documented
Fitters carry £5m public liability cover. We check leasehold and landlord consent before cutting anything, and we will not cut a communal fire door — that would void its rating and the block's fire strategy.
Fixed prices
Cat flap fitting prices in Colindale
Fixed prices for NW9 and the rest of Barnet. The material sets the price. Timber is quickest, uPVC and composite need capping, and a masonry wall means core drilling and a lined tunnel.
| Job | From | Typical time | What sets the price |
|---|---|---|---|
| Timber door | £75 | 45–60 min | Cut, chamfered and sealed so the door edge does not swell in winter. |
| uPVC door panel | £95 | 1–1.5 hrs | The panel is cut in place with the frame protected, and the cut edge capped so water cannot track in. |
| Composite door | £120 | 1–2 hrs | A composite has a foam core between two skins; both faces must be cut cleanly and the core sealed. |
| Brick or block wall, up to 350mm | £190 | 2–3 hrs | Core-drilled both sides with a tunnel liner fitted, so the cavity is never left open. |
| Glass panel — cut-out supplied by a glazier | £110 | 1 hr | Toughened glass cannot be cut on site; we template it, fit the replacement pane and set the flap. |
| Microchip flap set-up and training mode | £25 | 15–20 min | Chips registered, curfew and selective entry configured, and the flap left on training setting. |

Scope
What's included in Colindale
The same scope across NW9, whether the job is a single item or a full room.
Included in the price
- On NW9 jobs: height set to your cat's chest, not to a standard measurement, with 80% of homes here being flats, planned around the stair or the lift
- In Colindale: cut edges sealed or capped so the door stays weatherproof, the way it is done on Colindale jobs
- Draught brush and seal fitted and the flap swing tested both ways — including cat flap fitting london
- Standard on Barnet bookings: microchip flap registered and left in training mode with the swing eased, arranged with London Borough of Barnet where the kerb needs it
Not included
- Cutting toughened or laminated glass on site — it must be replaced by a glazier, quoted separately if you need it arranged in NW9
- Fire doors in communal areas, where a cut-out would void the fire rating, which we refer on to the right trade in Colindale
- Structural openings through a lintel or an insulated cavity closer without a survey, handled by London Borough of Barnet or a specialist contractor instead

Colindale NW9 at a glance
Published figures for the neighbourhood that covers Colindale — the numbers that actually change a cat flap fitting quote.
Walk Colindale from The former Hendon Aerodrome and Colindale Gardens outwards and the inter-war pattern is obvious: 80% of the 7,659 households in NW9 live in flats, 20% in houses.
Private renting sits at 35% and owner-occupation at 32%; the first group books cat flap fitting at short notice, the second plans it.
Expect precast concrete panels and dense blockwork in Colindale, often with surface conduit — where 32% owner-occupation means the same home is booked again rather than a new tenant each year behind the plaster in NW9. That is why fixings are picked in the room rather than off a van shelf, and why drilling blind into a panel with reinforcement or a buried cable behind it on these streets — measured on the walk in from Colindale (Northern) rather than assumed from a map is the fault we are called back to undo.
Anyone who knows Colindale knows the pattern near The former Hendon Aerodrome and Colindale Gardens: the fastest-growing new-build district in north London, around the old aerodrome. We plan the NW9 visit around it. Colindale is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it.
Every new block requires booked goods lifts and loading bays; estate roads are gated. Nearest station is Colindale (Northern), and one fitter for doors and panels; two where a wall tunnel is core-drilled and the debris has to be carried out of a flat.
