Overview
Cat flap fitting in Hounslow TW3 is a fixed-price visit for renter-heavy homes in Hounslow, most of them mainly Edwardian. 18,207 households sit inside this TW3 patch, 43% of them flats, so we quote on access near Hounslow Heath rather than a London average.
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 high street with timed access; new blocks need booked lifts.
Most cat flap bookings are within 48 hours and take a single short visit. Hounslow Central (Piccadilly) is the nearest station, so a TW3 visit rarely needs a whole morning set aside.
We expect solid London stock brick in TW3, some of it dry-lined during a later refurbishment — the reality on the streets around Hounslow Heath in TW3, 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 on these streets — with 18% social-rented stock locally, block access is agreed with the estate office first.
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

Timber door starts at £75 in Hounslow, with this being London Borough of Hounslow territory, and every job is quoted as a fixed written price before a fitter is booked for Hounslow (TW3) addresses. The material sets the price. Timber is quickest, uPVC and composite need capping on Hounslow bookings, with 18,207 households on this patch, 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 around Hounslow Central (Piccadilly), so the door stays weatherproof. If it is glazed, a glazier supplies a pane with the cut-out across TW3.
Yes, in writing. 40% of Hounslow homes are privately rented, with this being a short walk from Hounslow Central (Piccadilly), and a flap cut without consent is a common deposit deduction in this 43% flats neighbourhood. Send the email and we fit to its conditions on this side of Hounslow.
Yes, from £190 for a wall up to 350mm — the usual answer in Hounslow on the streets near Hounslow Heath, with 18,207 households on this patch — and this being London Borough of Hounslow territory, where 43% 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 the Hounslow rounds — and a median age of 36 in this neighbourhood, with 40% of TW3 homes being privately rented, 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 Hounslow letting agents and managing agents ask for before work starts in a leasehold flat across TW3, with 18% social-rented stock nearby.
Cutting toughened or laminated glass on site — it must be replaced by a glazier; Fire doors in communal areas on the streets near Hounslow Heath, with Hounslow Heath a few streets away — and this being London Borough of Hounslow territory, 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 Hounslow TW3 price you agree is the price you pay across TW3, with 43% of homes here being flats.
All three. With 40% of Hounslow privately rented and 43% owner-occupied, roughly half the TW3 diary is agent- or landlord-instructed and invoiced separately from the person at the door on the Hounslow rounds, with 43% owner-occupation locally — and 18% social-rented stock nearby.
