Overview
Cat flap fitting in Southfields SW18 is a fixed-price visit for owner-occupier-led homes in Wandsworth, most of them mainly Edwardian. 3,815 households sit inside this SW18 patch, 44% of them flats, so we quote on access near The Southfields Grid and the AELTC entrance 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. Championship-fortnight parking bans, narrow Grid streets and permit bays.
Most cat flap bookings are within 48 hours and take a single short visit. Southfields (District) is the nearest station, so a SW18 visit rarely needs a whole morning set aside.
We expect some of it dry-lined during a later refurbishment — and solid London stock brick — and championship-fortnight parking bans, narrow grid streets and permit bays in SW18, 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 — the pattern behind 3,815 households inside the SW18 neighbourhood.
Fitters carry £1m public liability. 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 | What sets the price |
|---|---|---|
| Timber door | £75 | Cut, chamfered and sealed so the door edge does not swell in winter. |
| uPVC door panel | £95 | The panel is cut in place with the frame protected, and the cut edge capped so water cannot track in. |
| Composite door | £120 | 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 | Quoted per job — free quote | 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 | 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 | Quoted per job — free quote | Chips registered, curfew and selective entry configured, and the flap left on training setting. |
Prices are labour and fitting materials; the flap itself can be supplied at cost or you can provide your own. Glass cut-outs are quoted by a glazier and shown separately. Where a lease or a landlord consent is needed we will tell you before booking rather than after. Permits, ULEZ and the Congestion Charge where they apply are itemised.
Scope
Sulltan is the best handyman in London. He is very reliable and professional. I highly recommend.
I booked the services for putting together some new bedroom furniture. This was agreed for 3 pm. I got a call at 3pm to say they were going to be late and be there at 5, they arrived at 5:30. The workmanship and the guys who fitted it was excellent and they were very friendly… Read in full →
Adam and his friend assembled the wardrobe in no time and without any fuss, highly recommended.

Working in Southfields
The SW18 stock around The Southfields Grid and the AELTC entrance is mainly Edwardian. ONS records 44% flats, 56% houses and 3,815 households in Southfields.
33% of households rent privately and 61% own, which is why cat flap fitting demand here peaks around tenancy changeovers and completion dates.
Expect some of it dry-lined during a later refurbishment — and solid London stock brick — and championship-fortnight parking bans, narrow grid streets and permit bays behind the plaster in SW18. That is why fixings are picked in the room rather than off a van shelf, and why fixings landing in soft lime mortar joints instead of the brick body on these streets — the pattern behind 3,815 households inside the SW18 neighbourhood is the fault we are called back to undo.
Anyone who knows Southfields knows the pattern near The Southfields Grid and the AELTC entrance: the Grid — a planned Edwardian estate that becomes the Wimbledon gateway each June. We plan the SW18 visit around it. Southfields 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: championship-fortnight parking bans, narrow Grid streets and permit bays. Southfields (District) 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 Southfields, with The Southfields Grid and the AELTC entrance a few streets away, and every job is quoted as a fixed written price before a fitter is booked on Wandsworth bookings. The material sets the price. Timber is quickest, uPVC and composite need capping for Southfields (SW18) addresses, with this being a short walk from Southfields (District), 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 Southfields rounds, so the door stays weatherproof. If it is glazed, a glazier supplies a pane with the cut-out for Southfields (SW18) addresses.
Yes, in writing. 33% of Southfields homes are privately rented, with 3,815 households on this patch, and a flap cut without consent is a common deposit deduction on the Southfields rounds. Send the email and we fit to its conditions on Wandsworth bookings.
Yes,, quoted free for a wall up to 350mm — the usual answer in Southfields around Southfields (District) — and 44% of homes here being flats, with 61% owner-occupation locally, where 44% of homes are flats with glazed back doors: we core-drill and fit a lined tunnel.
Fitters carry £1m public liability. We check leasehold and landlord consent before cutting anything in this 44% flats neighbourhood, with 6% social-rented stock nearby — and 33% of SW18 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 Wandsworth letting agents and managing agents ask for before work starts in a leasehold flat for Southfields (SW18) addresses, with 33% of SW18 homes being privately rented.
Cutting toughened or laminated glass on site — it must be replaced by a glazier; Fire doors in communal areas in Southfields, with 6% social-rented stock nearby — and this being London Borough of Wandsworth 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 Southfields SW18 price you agree is the price you pay for Southfields (SW18) addresses, with 56% of Southfields homes being houses.
All three. With 33% of Southfields privately rented and 61% owner-occupied, roughly half the SW18 diary is agent- or landlord-instructed and invoiced separately from the person at the door around Southfields (District) — and 61% owner-occupation locally, with 56% of Southfields homes being houses.
