Overview
Booked mostly by renter-heavy households around Hendon Central, cat flap fitting here covers supply-free fitting from £75. With 58% of Hendon's 14,613 homes in flats, lift access and stair carries in NW4 shape the slot length we hold.
How it works
Step 1
Timber, uPVC, composite, glass or masonry — plus what is behind it. A cavity wall or a glazed panel changes the job completely.
Step 2
Measured to your cat's chest height, so an older or arthritic cat still uses it in two years' time.
Step 3
Template marked, cut from both faces to avoid blow-out, and the edge lined, capped or sealed.
Step 4
Flap fitted square, sealed against draughts and rain, and the fixings drawn up evenly so the frame does not bow.
Step 5
Microchips registered, curfew set if you want one, and the flap left in training mode with the mess cleared.
Why choose us
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. A41 and M1 approaches are fast and hard to load from; side streets have driveways.
Most cat flap bookings are within 48 hours and take a single short visit. Hendon Central (Northern) is the nearest station, so a NW4 visit rarely needs a whole morning set aside.
We expect dot-and-dab plasterboard over blockwork; locally that also means with metal stud partitions between rooms — and a41 and m1 approaches are fast and hard to load from; side streets have driveways in NW4, and we carry the anchors, through-fixings and long bits that match. The mistake we spend most time undoing here is short screws that grip only the board and slowly lever it off the dabs on these streets — which is what a 58% flat share across the ONS neighbourhood covering Hendon actually produces.
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
| 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

Working in Hendon
Walk Hendon from The RAF Museum London outwards and the inter-war pattern is obvious: 58% of the 14,613 households in NW4 live in flats, 42% in houses.
45% of households rent privately and 43% own, which is why cat flap fitting demand here peaks around tenancy changeovers and completion dates.
Hendon substrates run to dot-and-dab plasterboard over blockwork; locally that also means with metal stud partitions between rooms — and a41 and m1 approaches are fast and hard to load from; side streets have driveways. Nothing is drilled until the wall has been sounded, because short screws that grip only the board and slowly lever it off the dabs on these streets — which is what a 58% flat share across the ONS neighbourhood covering Hendon actually produces is the mistake that costs a NW4 customer twice.
Anyone who knows Hendon knows the pattern near The RAF Museum London: university campus, Brent Street's shops and the RAF Museum on the old aerodrome. We plan the NW4 visit around it. Hendon is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it.
Getting to the door matters as much as the job: a41 and M1 approaches are fast and hard to load from; side streets have driveways. Hendon Central (Northern) is the nearest station, 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.
