Booked around your day
Most cat flap bookings are within 48 hours and take a single short visit. Clapham Common (Northern) is the nearest station, so a SW4 visit rarely needs a whole morning set aside.

Same-week slots · Fully insured · Local Clapham fitters · Fixed written pricesBooking cat flap fitting near Clapham Common? Very tight CPZ hours, narrow terraces and share-house turnover every summer, and that is planned into the slot rather than discovered on the day. Prices start at £75 and are fixed before we travel. Doors are checked for glazing and fire rating before cutting.


Overview
This page prices cat flap fitting for Clapham SW4 specifically: Georgian and early Victorian stock, 34% privately rented and 21,167 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
Most cat flap bookings are within 48 hours and take a single short visit. Clapham Common (Northern) is the nearest station, so a SW4 visit rarely needs a whole morning set aside.
We expect lath and plaster over timber studs; locally that also means with solid brick on the party and external walls, measured on the walk in from Clapham Common (Northern) rather than assumed from a map in SW4, 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; locally that also means which crumbles the key and drops the panel, a median age of 32 in this neighbourhood shapes what gets ordered here.
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. Very tight CPZ hours, narrow terraces and share-house turnover every summer.
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.
I booked online last minute, as I needed a handyman urgently for the next day. When I called Hello Services, I spoke to Michelle and she was extremely helpful and arranged everything within 15 mins. Adam the handy man then came to fix my wardrobe sliding door, which were jammed and came off the ledge… Read in full →

Working in Clapham
21,167 households sit inside the SW4 neighbourhood covering Clapham. The build is Georgian and early Victorian, the tenure profile mixed-tenure, and 76% of those homes are flats.
The mixed-tenure mix here (37% owned, 34% privately rented) means a SW4 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Expect lath and plaster over timber studs; locally that also means with solid brick on the party and external walls, measured on the walk in from Clapham Common (Northern) rather than assumed from a map behind the plaster in SW4. That is why fixings are picked in the room rather than off a van shelf, and why a plasterboard plug spun into lime plaster; locally that also means which crumbles the key and drops the panel, a median age of 32 in this neighbourhood shapes what gets ordered here is the fault we are called back to undo.
Clapham 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 — the Common, Abbeville Village and the Old Town's Georgian houses — which is why a SW4 quote is not a Lambeth average.
Very tight CPZ hours, narrow terraces and share-house turnover every summer. Nearest station is Clapham Common (Northern), 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 Clapham, with Lambeth parking rules in play, and every job is quoted as a fixed written price before a fitter is booked for Clapham (SW4) addresses. The material sets the price. Timber is quickest, uPVC and composite need capping on Lambeth bookings, with 21,167 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 in Clapham, so the door stays weatherproof. If it is glazed, a glazier supplies a pane with the cut-out on Lambeth bookings.
Yes, in writing. 34% of Clapham homes are privately rented, with a median age of 32 in this neighbourhood, and a flap cut without consent is a common deposit deduction on SW4 jobs. Send the email and we fit to its conditions on the streets near Clapham Common.
Yes, from £190 for a wall up to 350mm — the usual answer in Clapham on the streets near Clapham Common — and 31% one-person households here, with Lambeth parking rules in play, where 76% of homes are flats with glazed back doors: we core-drill and fit a lined tunnel.
Cutting toughened or laminated glass on site — it must be replaced by a glazier; Fire doors in communal areas on the Clapham rounds, with 30% social-rented stock nearby — and this being a short walk from Clapham Common (Northern), 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 Clapham SW4 price you agree is the price you pay on SW4 jobs, with 24% of Clapham homes being houses.
All three. With 34% of Clapham privately rented and 37% owner-occupied, roughly half the SW4 diary is agent- or landlord-instructed and invoiced separately from the person at the door on the Clapham rounds — and 24% of Clapham homes being houses, with 31% one-person households here.
Clapham Common is the marker we route to in this 76% flats neighbourhood, with a median age of 32 in this neighbourhood, and very tight CPZ hours, narrow terraces and share-house turnover every summer. A SW4 slot added to an existing Lambeth round usually lands the same week rather than the next on Lambeth bookings, with 21,167 households on this patch.
