Overview
Cat flap fitting in Belsize Park NW3 is a fixed-price visit for renter-heavy homes in Camden, most of them mainly Victorian. 3,000 households sit inside this NW3 patch, 93% of them flats, so we quote on access near Belsize Village rather than a London average.
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. Resident-permit streets, hill gradients and conversion flats up three or four flights.
Most cat flap bookings are within 48 hours and take a single short visit. Belsize Park (Northern) is the nearest station, so a NW3 visit rarely needs a whole morning set aside.
We expect lath and plaster over timber studs in Belsize Park, with solid brick on the party and external walls — the pattern behind 3,000 households inside the NW3 neighbourhood in NW3, and we carry the anchors, through-fixings and long bits that match. The mistake we spend most time undoing here is a plasterboard plug spun into lime plaster in NW3, which crumbles the key and drops the panel — measured on the walk in from Belsize Park (Northern) rather than assumed from a map.
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
Sulltan is the best handyman in London. He is very reliable and professional. I highly recommend.

Working in Belsize Park
Walk Belsize Park from Belsize Village outwards and the mainly Victorian pattern is obvious: 93% of the 3,000 households in NW3 live in flats, 7% in houses.
Owner-occupation runs at 39% in Belsize Park, so alongside the 51% rental churn there is steady planned work — refurbishments, downsizes and probate clearances booked weeks ahead.
Belsize Park substrates run to lath and plaster over timber studs in Belsize Park, with solid brick on the party and external walls — the pattern behind 3,000 households inside the NW3 neighbourhood. Nothing is drilled until the wall has been sounded, because a plasterboard plug spun into lime plaster in NW3, which crumbles the key and drops the panel — measured on the walk in from Belsize Park (Northern) rather than assumed from a map is the mistake that costs a NW3 customer twice.
Anyone who knows Belsize Park knows the pattern near Belsize Village: stucco villas and mansion blocks on the slope between Hampstead and Chalk Farm. We plan the NW3 visit around it. Belsize Park sits inside the Congestion Charge zone as well as ULEZ, so both are itemised on the quote rather than absorbed into an hourly rate.
Getting to the door matters as much as the job: resident-permit streets, hill gradients and conversion flats up three or four flights. Belsize Park (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.

Timber door starts at £75 in Belsize Park on Camden bookings, with a median age of 38 in this neighbourhood, and every job is quoted as a fixed written price before a fitter is booked. The material sets the price.
