Same-week slots · Fully insured · Local Monument and Eastcheap fitters · Fixed written pricesLooking for cat flap fitting in Monument and Eastcheap EC3?

Fixed written quote from £75, insured fitters, the cut edge sealed and the flap set up.


Overview
This page prices cat flap fitting for Monument and Eastcheap EC3 specifically: recent new-build stock, 48% privately rented and 4,914 households in total. Work starts at £75, fixed in writing, with parking and City of London Corporation permit rules costed before an insured fitter travels.
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
Most cat flap bookings are within 48 hours and take a single short visit. Monument (Circle, District) is the nearest station, so a EC3 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, which is why City of London Corporation kerb rules get settled before the van is loaded in EC3, 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, as the Monument and Eastcheap stock goes, where 37% owner-occupation means the same home is booked again rather than a new tenant each year.
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. Lower Thames Street is a red route; the lanes behind take a small van only.
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. |

Working in Monument and Eastcheap
Monument and Eastcheap EC3 is recent new-build and renter-heavy: 98% of homes here are flats and 2% are houses, across 4,914 households (ONS Census 2021).
With 48% private renting against 37% owner-occupied, most EC3 bookings land on a move-in day rather than a weekend.
Walls are dot-and-dab plasterboard over blockwork; locally that also means with metal stud partitions between rooms, which is why City of London Corporation kerb rules get settled before the van is loaded, so the fixing that matters in Monument and Eastcheap is chosen on site — the usual failure here is short screws that grip only the board and slowly lever it off the dabs, as the Monument and Eastcheap stock goes, where 37% owner-occupation means the same home is booked again rather than a new tenant each year.
Monument and Eastcheap sits inside the Congestion Charge zone as well as ULEZ, so both are itemised on the quote rather than absorbed into an hourly rate. What shapes the job more is the neighbourhood itself — riverside City streets between London Bridge and the Tower, dense with narrow lanes — which is why a EC3 quote is not a City of London average.
Getting to the door matters as much as the job: lower Thames Street is a red route; the lanes behind take a small van only. Monument (Circle, District) 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 Monument and Eastcheap in this 98% flats neighbourhood, with 15% social-rented stock nearby, and every job is quoted as a fixed written price before a fitter is booked. The material sets the price. Timber is quickest, uPVC and composite need capping across EC3, with this being a short walk from Monument (Circle, District), and a masonry wall means core drilling and a lined tunnel.
Yes — £95, an hour to 90 minutes. The panel is cut in place and the edge capped on City of London bookings, so the door stays weatherproof. If it is glazed, a glazier supplies a pane with the cut-out on the streets near The Monument to the Great Fire.
Yes, in writing. 48% of Monument and Eastcheap homes are privately rented around Monument (Circle, District), with 2% of Monument and Eastcheap homes being houses, and a flap cut without consent is a common deposit deduction. Send the email and we fit to its conditions across EC3.

Lower Thames Street is a red route; the lanes behind take a small van only on EC3 jobs.

Fitters carry £5m public liability cover. We check leasehold and landlord consent before cutting anything across EC3, with this being City of London Corporation territory — and 2% of Monument and Eastcheap homes being houses, and we will not cut a communal fire door — that would void its rating and the block's fire strategy. That paperwork is what most City of London letting agents and managing agents ask for before work starts in a leasehold flat around Monument (Circle, District), with 51% one-person households here.
Cutting toughened or laminated glass on site — it must be replaced by a glazier; Fire doors in communal areas in this 98% flats neighbourhood, with 48% of EC3 homes being privately rented — and 2% of Monument and Eastcheap homes being houses, where a cut-out would void the fire rating; Structural openings through a lintel or an insulated cavity closer without a survey. Anything outside that scope is quoted separately so the Monument and Eastcheap EC3 price you agree is the price you pay on City of London bookings, with this being City of London Corporation territory.
