Booked around your day

Kensington and Chelsea · SW3 · Cat flap fitting
Same-week slots · Fully insured · Local Chelsea fitters · Fixed written pricesLooking for cat flap fitting in Chelsea SW3? We work in Chelsea most weeks — king's Road shops, Cadogan estate squares and the river at Chelsea Embankment — and price cat flap fitting against that reality rather than a London average. Fixed written quote from £75, insured fitters, the cut edge sealed and the flap set up.


Overview
This page prices cat flap fitting for Chelsea SW3 specifically: Georgian and early Victorian stock, 35% privately rented and 8,944 households in total. Work starts at £75, fixed in writing, with parking and Royal Borough of Kensington and Chelsea 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. Sloane Square (Circle, District) is the nearest station, so a SW3 visit rarely needs a whole morning set aside.
We expect lath and plaster over timber studs in SW3, with solid brick on the party and external walls, a median age of 44 in this neighbourhood shapes what gets ordered here in SW3, 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 Chelsea, which crumbles the key and drops the panel, the reality on the streets around The Royal Hospital Chelsea.
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. Cadogan estate parking rules, King's Road red-route loading and mews arches with height limits.
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 Chelsea
In Chelsea (SW3) the split is 78% flats to 22% houses over 8,944 households, and the stock is Georgian and early Victorian.
The mixed-tenure mix here (38% owned, 35% privately rented) means a SW3 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Chelsea substrates run to lath and plaster over timber studs in SW3, with solid brick on the party and external walls, a median age of 44 in this neighbourhood shapes what gets ordered here. Nothing is drilled until the wall has been sounded, because a plasterboard plug spun into lime plaster in Chelsea, which crumbles the key and drops the panel, the reality on the streets around The Royal Hospital Chelsea is the mistake that costs a SW3 customer twice.
Chelsea 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 — king's Road shops, Cadogan estate squares and the river at Chelsea Embankment — which is why a SW3 quote is not a Kensington and Chelsea average.
On access, cadogan estate parking rules, King's Road red-route loading and mews arches with height limits — 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 Sloane Square (Circle, District).

Timber door starts at £75 in Chelsea, with this being Royal Borough of Kensington and Chelsea territory, and every job is quoted as a fixed written price before a fitter is booked on the Chelsea rounds. The material sets the price. Timber is quickest, uPVC and composite need capping on the streets near The Royal Hospital Chelsea, with Kensington and Chelsea parking rules in play, 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 Chelsea rounds, so the door stays weatherproof. If it is glazed, a glazier supplies a pane with the cut-out across SW3.
Yes, in writing. 35% of Chelsea homes are privately rented, with 38% owner-occupation locally, and a flap cut without consent is a common deposit deduction across SW3. Send the email and we fit to its conditions on this side of Kensington and Chelsea.
Yes, from £190 for a wall up to 350mm — the usual answer in Chelsea around Sloane Square (Circle, District), with Kensington and Chelsea parking rules in play — and 78% of homes here being flats, where 78% 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 SW3 jobs — and 8,944 households on this patch, with 22% of Chelsea 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. Anything outside that scope is quoted separately so the Chelsea SW3 price you agree is the price you pay around Sloane Square (Circle, District), with The Royal Hospital Chelsea a few streets away.
All three. With 35% of Chelsea privately rented and 38% owner-occupied, roughly half the SW3 diary is agent- or landlord-instructed and invoiced separately from the person at the door in Chelsea — and 8,944 households on this patch, with 45% one-person households here.
The Royal Hospital Chelsea is the marker we route to on this side of Kensington and Chelsea, with 35% of SW3 homes being privately rented, and cadogan estate parking rules, King's Road red-route loading and mews arches with height limits. A SW3 slot added to an existing Kensington and Chelsea round usually lands the same week rather than the next on SW3 jobs, with this being a short walk from Sloane Square (Circle, District).
