Overview
Cat flap fitting in Barnsbury N1 is a fixed-price visit for social-housing-led homes in Islington, most of them Georgian and early Victorian. 7,513 households sit inside this N1 patch, 81% of them flats, so we quote on access near Thornhill Square 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. Low-traffic neighbourhood filters, narrow squares and heavy basement-step access.
Most cat flap bookings are within 48 hours and take a single short visit. Caledonian Road & Barnsbury (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 Barnsbury, 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 drilling blind into a panel with reinforcement or a buried cable behind it on these streets — the pattern behind 7,513 households inside the N1 neighbourhood.
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 Barnsbury
Census 2021 puts Barnsbury at 7,513 households with a median age of 33.2. The Georgian and early Victorian stock is social-housing-led, which is why 19% houses and 81% flats need different handling in N1.
Private renting sits at 30% and owner-occupation at 27%; the first group books cat flap fitting at short notice, the second plans it.
Expect precast concrete panels and dense blockwork in N1, often with surface conduit — and with 35% one-person households in Barnsbury, 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 drilling blind into a panel with reinforcement or a buried cable behind it on these streets — the pattern behind 7,513 households inside the N1 neighbourhood is the fault we are called back to undo.
Anyone who knows Barnsbury knows the pattern near Thornhill Square: conservation-area squares and crescents west of Upper Street. We plan the N1 visit around it. Barnsbury sits inside the Congestion Charge zone as well as ULEZ, so both are itemised on the quote rather than absorbed into an hourly rate.
Low-traffic neighbourhood filters, narrow squares and heavy basement-step access. Nearest station is Caledonian Road & Barnsbury (Overground), 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.
