Overview
This page prices cat flap fitting for Sydenham SE26 specifically: mainly Victorian stock, 22% privately rented and 9,790 households in total. Work starts at £75, fixed in writing, with parking and London Borough of Lewisham 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
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. Steep hills, high-street loading windows and narrow side streets.
Most cat flap bookings are within 48 hours and take a single short visit. Sydenham (Overground) is the nearest station, so a SE26 visit rarely needs a whole morning set aside.
We expect precast concrete panels and dense blockwork in Sydenham, often with surface conduit — the reality on the streets around Sydenham Wells Park in SE26, 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 — which is why London Borough of Lewisham kerb rules get settled before the van is loaded.
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

Working in Sydenham
Walk Sydenham from Sydenham Wells Park outwards and the mainly Victorian pattern is obvious: 64% of the 9,790 households in SE26 live in flats, 36% in houses.
Private renting sits at 22% and owner-occupation at 45%; the first group books cat flap fitting at short notice, the second plans it.
Walls are precast concrete panels and dense blockwork in Sydenham, often with surface conduit — the reality on the streets around Sydenham Wells Park, so the fixing that matters in Sydenham is chosen on site — the usual failure here is drilling blind into a panel with reinforcement or a buried cable behind it on these streets — which is why London Borough of Lewisham kerb rules get settled before the van is loaded.
Anyone who knows Sydenham knows the pattern near Sydenham Wells Park: a long high street on the hill where the Crystal Palace once stood nearby. We plan the SE26 visit around it. Sydenham is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it.
Getting to the door matters as much as the job: steep hills, high-street loading windows and narrow side streets. Sydenham (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.

Timber door starts at £75 in Sydenham, with 64% of homes here being flats, and every job is quoted as a fixed written price before a fitter is booked in this 64% flats neighbourhood. The material sets the price. Timber is quickest, uPVC and composite need capping in Sydenham, with a median age of 37 in this neighbourhood, 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 Lewisham bookings, so the door stays weatherproof. If it is glazed, a glazier supplies a pane with the cut-out in Sydenham.
Yes, in writing. 22% of Sydenham homes are privately rented, with a median age of 37 in this neighbourhood, and a flap cut without consent is a common deposit deduction in this 64% flats neighbourhood. Send the email and we fit to its conditions on this side of Lewisham.
Yes, from £190 for a wall up to 350mm — the usual answer in Sydenham around Sydenham (Overground) — and 22% of SE26 homes being privately rented, with Lewisham parking rules in play, where 64% 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 on SE26 jobs, with Sydenham Wells Park a few streets away — and 36% of Sydenham 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 Lewisham letting agents and managing agents ask for before work starts in a leasehold flat on this side of Lewisham, with 45% owner-occupation locally.
Cutting toughened or laminated glass on site — it must be replaced by a glazier; Fire doors in communal areas on Lewisham bookings, with 64% of homes here being flats — and 36% of Sydenham 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 Sydenham SE26 price you agree is the price you pay on the Sydenham rounds, with this being London Borough of Lewisham territory.
All three. With 22% of Sydenham privately rented and 45% owner-occupied, roughly half the SE26 diary is agent- or landlord-instructed and invoiced separately from the person at the door in this 64% flats neighbourhood — and Sydenham Wells Park a few streets away, with this being London Borough of Lewisham territory.
