Same-week slots · Fully insured · Local Canonbury fitters · Fixed written pricesWe provide cat flap fitting in Canonbury N1 for houses and flats around Canonbury Tower and Canonbury Square. From £75, quoted in writing before the visit, with 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 Doors are checked for glazing and fire rating before cutting.


Overview
Booked mostly by social-housing-led households around Canonbury, cat flap fitting here covers supply-free fitting from £75. With 84% of Canonbury's 9,497 homes in flats, lift access and stair carries in N1 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
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.
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. Conservation-area streets, narrow entrances and no vehicle access through the square gardens.
Most cat flap bookings are within 48 hours and take a single short visit. Canonbury (Overground) is the nearest station, so a N1 visit rarely needs a whole morning set aside.
We expect precast concrete panels and dense blockwork in N1, often with surface conduit, and with 35% one-person households in Canonbury, one adult is usually the only pair of hands on site in N1, and we carry the anchors, through-fixings and long bits that match. The mistake we spend most time undoing here is Canonbury gives us drilling blind into a panel with reinforcement or a buried cable behind it, which is what a 84% flat share across the ONS neighbourhood covering Canonbury actually produces.
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 Canonbury
In Canonbury (N1) the split is 84% flats to 16% houses over 9,497 households, and the stock is Georgian and early Victorian.
Because 28% of Canonbury is privately rented and 44% socially rented, a lot of N1 work is agreed with a landlord or managing agent rather than the person opening the door.
Expect precast concrete panels and dense blockwork in N1, often with surface conduit, and with 35% one-person households in Canonbury, one adult is usually the only pair of hands on site behind the plaster in N1. That is why fixings are picked in the room rather than off a van shelf, and why Canonbury gives us drilling blind into a panel with reinforcement or a buried cable behind it, which is what a 84% flat share across the ONS neighbourhood covering Canonbury actually produces is the fault we are called back to undo.
Quiet conservation streets of Georgian squares between Essex Road and Highbury. That character decides the practical detail of cat flap fitting here far more than the borough boundary does. Canonbury 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: conservation-area streets, narrow entrances and no vehicle access through the square gardens. Canonbury (Overground) 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.
