Overview
This page prices cat flap fitting for Herne Hill SE24 specifically: mainly Victorian stock, 19% privately rented and 3,150 households in total. Work starts at £75, fixed in writing, with parking and London Borough of Southwark 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. Herne Hill (Thameslink, Southeastern) is the nearest station, so a SE24 visit rarely needs a whole morning set aside.
We expect some of it dry-lined during a later refurbishment, over solid London stock brick, a median age of 41 in this neighbourhood shapes what gets ordered here in SE24, and we carry the anchors, through-fixings and long bits that match. The mistake we spend most time undoing here is fixings landing in soft lime mortar joints instead of the brick body, as the Herne Hill stock goes, and with 19% of homes here privately rented, it sets the booking date as often as the job does.
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. Railway-bridge height limits on Half Moon Lane and permit-only side streets.
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 Herne Hill
In Herne Hill (SE24) the split is 27% flats to 73% houses over 3,150 households, and the stock is mainly Victorian.
The owner-occupier-led mix here (69% owned, 19% privately rented) means a SE24 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Walls are some of it dry-lined during a later refurbishment, over solid London stock brick, a median age of 41 in this neighbourhood shapes what gets ordered here, so the fixing that matters in Herne Hill is chosen on site — the usual failure here is fixings landing in soft lime mortar joints instead of the brick body, as the Herne Hill stock goes, and with 19% of homes here privately rented, it sets the booking date as often as the job does.
Herne Hill 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 — brockwell Park, the velodrome and a compact village of independents — which is why a SE24 quote is not a Southwark average.
Railway-bridge height limits on Half Moon Lane and permit-only side streets. Nearest station is Herne Hill (Thameslink, Southeastern), 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.

Cutting toughened or laminated glass on site — it must be replaced by a glazier; Fire doors in communal areas around Herne Hill (Thameslink, Southeastern) — and 27% of homes here being flats, with 73% of Herne Hill 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.
