Overview
This page prices cat flap fitting for Sidcup DA15 specifically: inter-war stock, 20% privately rented and 8,640 households in total. Work starts at £75, fixed in writing, with parking and London Borough of Bexley 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. Driveways throughout; the high street is a red route with short bays.
Most cat flap bookings are within 48 hours and take a single short visit. Sidcup (Southeastern) is the nearest station, so a DA15 visit rarely needs a whole morning set aside.
We expect timber stud partitions inside; locally that also means cavity brickwork outside — where 68% owner-occupation means the same home is booked again rather than a new tenant each year in DA15, and we carry the anchors, through-fixings and long bits that match. The mistake we spend most time undoing here is a four-hole bracket with two screws in a stud and two in fresh air on these streets — and driveways throughout; the high street is a red route with short bays.
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 Sidcup
Census 2021 puts Sidcup at 8,640 households with a median age of 40.8. The inter-war stock is owner-occupier-led, which is why 54% houses and 46% flats need different handling in DA15.
Owner-occupation runs at 68% in Sidcup, so alongside the 20% rental churn there is steady planned work — refurbishments, downsizes and probate clearances booked weeks ahead.
Walls are timber stud partitions inside; locally that also means cavity brickwork outside — where 68% owner-occupation means the same home is booked again rather than a new tenant each year, so the fixing that matters in Sidcup is chosen on site — the usual failure here is a four-hole bracket with two screws in a stud and two in fresh air on these streets — and driveways throughout; the high street is a red route with short bays.
Anyone who knows Sidcup knows the pattern near Sidcup Place and Lamorbey Park: a busy high street, Lamorbey Park and the Rose Bruford campus. We plan the DA15 visit around it. Sidcup 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: driveways throughout; the high street is a red route with short bays. Sidcup (Southeastern) 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 Sidcup, with 46% of homes here being flats, and every job is quoted as a fixed written price before a fitter is booked on Bexley bookings. The material sets the price. Timber is quickest, uPVC and composite need capping on DA15 jobs, with a median age of 41 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 the Sidcup rounds, so the door stays weatherproof. If it is glazed, a glazier supplies a pane with the cut-out for Sidcup (DA15) addresses.
Yes, in writing. 20% of Sidcup homes are privately rented, with 68% owner-occupation locally, and a flap cut without consent is a common deposit deduction across DA15. Send the email and we fit to its conditions on the streets near Sidcup Place and Lamorbey Park.
Yes, from £190 for a wall up to 350mm — the usual answer in Sidcup on Bexley bookings, with 68% owner-occupation locally — and 8,640 households on this patch, where 46% 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 in this 46% flats neighbourhood, with 35% one-person households here, 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 Bexley letting agents and managing agents ask for before work starts in a leasehold flat for Sidcup (DA15) addresses, with this being London Borough of Bexley territory.
Cutting toughened or laminated glass on site — it must be replaced by a glazier; Fire doors in communal areas on the Sidcup rounds, with 35% one-person households here — and 54% of Sidcup 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 Sidcup DA15 price you agree is the price you pay on DA15 jobs, with Bexley parking rules in play.
All three. With 20% of Sidcup privately rented and 68% owner-occupied, roughly half the DA15 diary is agent- or landlord-instructed and invoiced separately from the person at the door on Bexley bookings — and 35% one-person households here, with this being a short walk from Sidcup (Southeastern).
