Overview
This page prices cat flap fitting for Streatham SW16 specifically: mainly Edwardian stock, 35% privately rented and 26,325 households in total. Work starts at £75, fixed in writing, with parking and London Borough of Lambeth 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
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. A23 red route, side streets with permit bays and mansion blocks with small lifts.
Most cat flap bookings are within 48 hours and take a single short visit. Streatham (Thameslink, Southern) is the nearest station, so a SW16 visit rarely needs a whole morning set aside.
We expect lath and plaster over timber studs in Streatham, with solid brick on the party and external walls, which is what a 66% flat share across the ONS neighbourhood covering Streatham actually produces in SW16, and we carry the anchors, through-fixings and long bits that match. The mistake we spend most time undoing here is a plasterboard plug spun into lime plaster in Streatham, which crumbles the key and drops the panel, and with 35% of homes here privately rented, it sets the booking date as often as the job does.
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 Streatham
In Streatham (SW16) the split is 66% flats to 34% houses over 26,325 households, and the stock is mainly Edwardian.
With 35% private renting against 44% owner-occupied, most SW16 bookings land on a move-in day rather than a weekend.
Streatham substrates run to lath and plaster over timber studs in Streatham, with solid brick on the party and external walls, which is what a 66% flat share across the ONS neighbourhood covering Streatham actually produces. Nothing is drilled until the wall has been sounded, because a plasterboard plug spun into lime plaster in Streatham, which crumbles the key and drops the panel, and with 35% of homes here privately rented, it sets the booking date as often as the job does is the mistake that costs a SW16 customer twice.
A two-mile high road, the common and the ice rink, with Edwardian streets either side. That character decides the practical detail of cat flap fitting here far more than the borough boundary does. Streatham sits inside the Congestion Charge zone as well as ULEZ, so both are itemised on the quote rather than absorbed into an hourly rate.
On access, a23 red route, side streets with permit bays and mansion blocks with small lifts — one reason 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. Fitters travelling in use Streatham (Thameslink, Southern).

Timber door starts at £75 in Streatham, with 44% owner-occupation locally, and every job is quoted as a fixed written price before a fitter is booked across SW16. The material sets the price. Timber is quickest, uPVC and composite need capping in this 66% flats neighbourhood, with 30% one-person households here, 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 Lambeth bookings, so the door stays weatherproof. If it is glazed, a glazier supplies a pane with the cut-out on the streets near Streatham Common and the Rookery.

A23 red route, side streets with permit bays and mansion blocks with small lifts on the Streatham rounds.

Fitters carry £5m public liability cover. We check leasehold and landlord consent before cutting anything in this 66% flats neighbourhood, with 44% owner-occupation locally — and 21% social-rented stock nearby, and we will not cut a communal fire door — that would void its rating and the block's fire strategy.

Cutting toughened or laminated glass on site — it must be replaced by a glazier; Fire doors in communal areas for Streatham (SW16) addresses, with 44% owner-occupation locally, 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 Streatham SW16 price you agree is the price you pay on the streets near Streatham Common and the Rookery, with 21% social-rented stock nearby.
