Overview
Cat flap fitting in Northwood HA6 is a fixed-price visit for owner-occupier-led homes in Harrow, most of them period conversion. 7,999 households sit inside this HA6 patch, 38% of them flats, so we quote on access near Northwood Golf Club 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
We expect timber stud partitions inside in HA6, cavity brickwork outside — a median age of 40 in this neighbourhood shapes what gets ordered here in HA6, and we carry the anchors, through-fixings and long bits that match. The mistake we spend most time undoing here is in HA6, a four-hole bracket with two screws in a stud and two in fresh air — and with 29% one-person households in Northwood, one adult is usually the only pair of hands on site.
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.
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. Long driveways and gated entrances; roads are wide and easy for a Luton.
Most cat flap bookings are within 48 hours and take a single short visit. Northwood (Metropolitan) is the nearest station, so a HA6 visit rarely needs a whole morning set aside.
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 Northwood

Private renting sits at 25% and owner-occupation at 60%; the first group books cat flap fitting at short notice, the second plans it.
Expect timber stud partitions inside in HA6, cavity brickwork outside — a median age of 40 in this neighbourhood shapes what gets ordered here behind the plaster in HA6. That is why fixings are picked in the room rather than off a van shelf, and why in HA6, a four-hole bracket with two screws in a stud and two in fresh air — and with 29% one-person households in Northwood, one adult is usually the only pair of hands on site is the fault we are called back to undo.
Two streets can behave very differently in Northwood: affluent Metroland suburb of large houses, private schools and golf courses. The quote reflects the street the job is actually on. Northwood is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it.
On access, long driveways and gated entrances; roads are wide and easy for a Luton — 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 Northwood (Metropolitan).

Timber door starts at £75 in Northwood, with this being a short walk from Northwood (Metropolitan), and every job is quoted as a fixed written price before a fitter is booked in this 38% flats neighbourhood. The material sets the price. Timber is quickest, uPVC and composite need capping across HA6, with Northwood Golf Club a few streets away, 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 this side of Harrow, so the door stays weatherproof.

Fitters carry £1m public liability. We check leasehold and landlord consent before cutting anything on this side of Harrow, with this being a short walk from Northwood (Metropolitan) — and 25% of HA6 homes being privately rented, 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 in this 38% flats neighbourhood — and this being a short walk from Northwood (Metropolitan), with Northwood Golf Club a few streets away, 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 Northwood HA6 price you agree is the price you pay on Harrow bookings, with 25% of HA6 homes being privately rented.
All three. With 25% of Northwood privately rented and 60% owner-occupied, roughly half the HA6 diary is agent- or landlord-instructed and invoiced separately from the person at the door for Northwood (HA6) addresses — and this being London Borough of Harrow territory, with this being a short walk from Northwood (Metropolitan).
