Cathedral precinct, One New Change shopping and the streets running down to the Millennium Bridge, which is why our EC4 quotes account for pedestrianised zones and camera-enforced streets; loading needs a permit from the Corporation. You get a fixed price in writing, an insured fitter and a tidy finish.


Overview
Booked mostly by renter-heavy households around St Paul's, cat flap fitting here covers supply-free fitting from £75. With 98% of St Paul's's 4,914 homes in flats, lift access and stair carries in EC4 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. Pedestrianised zones and camera-enforced streets; loading needs a permit from the Corporation.
Most cat flap bookings are within 48 hours and take a single short visit. St Paul's (Central) is the nearest station, so a EC4 visit rarely needs a whole morning set aside.
We expect dot-and-dab plasterboard over blockwork in EC4, with metal stud partitions between rooms — measured on the walk in from St Paul's (Central) rather than assumed from a map in EC4, 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 — the pattern behind 4,914 households inside the EC4 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 St Paul's
Walk St Paul's from St Paul's Cathedral outwards and the post-war pattern is obvious: 98% of the 4,914 households in EC4 live in flats, 2% in houses.
Owner-occupation runs at 37% in St Paul's, so alongside the 48% rental churn there is steady planned work — refurbishments, downsizes and probate clearances booked weeks ahead.
Walls are dot-and-dab plasterboard over blockwork in EC4, with metal stud partitions between rooms — measured on the walk in from St Paul's (Central) rather than assumed from a map, so the fixing that matters in St Paul's is chosen on site — the usual failure here is short screws that grip only the board and slowly lever it off the dabs on these streets — the pattern behind 4,914 households inside the EC4 neighbourhood.
Anyone who knows St Paul's knows the pattern near St Paul's Cathedral: cathedral precinct, One New Change shopping and the streets running down to the Millennium Bridge. We plan the EC4 visit around it. St Paul's 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: pedestrianised zones and camera-enforced streets; loading needs a permit from the Corporation. St Paul's (Central) 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 St Paul's on the streets near St Paul's Cathedral, with 4,914 households on this patch, 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 on this side of City of London, with City of London parking rules in play, 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 EC4 jobs, so the door stays weatherproof. If it is glazed, a glazier supplies a pane with the cut-out on the streets near St Paul's Cathedral.
Yes, in writing. 48% of St Paul's homes are privately rented around St Paul's (Central), with 98% of homes here being flats, and a flap cut without consent is a common deposit deduction. Send the email and we fit to its conditions in this 98% flats neighbourhood.
Yes, from £190 for a wall up to 350mm — the usual answer in St Paul's across EC4, with City of London parking rules in play — and St Paul's Cathedral a few streets away, where 98% of homes are flats with glazed back doors: we core-drill and fit a lined tunnel.
Fitters carry £5m public liability cover. We check leasehold and landlord consent before cutting anything for St Paul's (EC4) addresses — and 4,914 households on this patch, with this being a short walk from St Paul's (Central), 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 on the St Paul's rounds, 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 across EC4, with 15% social-rented stock nearby — and St Paul's Cathedral a few streets away, 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 St Paul's EC4 price you agree is the price you pay on this side of City of London, with 2% of St Paul's homes being houses.
All three. With 48% of St Paul's privately rented and 37% owner-occupied, roughly half the EC4 diary is agent- or landlord-instructed and invoiced separately from the person at the door in St Paul's — and 37% owner-occupation locally, with 2% of St Paul's homes being houses.
