Insured and documented
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.

Same-week slots · Fully insured · Local Old Street fitters · Fixed written pricesLooking for cat flap fitting in Old Street EC1V? We work in Old Street most weeks — the roundabout, tech offices and warehouse conversions on the City fringe — 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
Cat flap fitting in Old Street EC1V is a fixed-price visit for social-housing-led homes in Islington, most of them post-war. 4,949 households sit inside this EC1V patch, 98% of them flats, so we quote on access near Old Street roundabout and Bunhill Fields burial ground 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
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. Red-route roundabout with no kerbside loading, goods-lift booking in the towers and gated estate yards.
Most cat flap bookings are within 48 hours and take a single short visit. Old Street (Northern, Great Northern) is the nearest station, so a EC1V visit rarely needs a whole morning set aside.
We expect often with surface conduit — and precast concrete panels and dense blockwork, measured on the walk in from Old Street (Northern, Great Northern) rather than assumed from a map in EC1V, and we carry the anchors, through-fixings and long bits that match. The mistake we spend most time undoing here is Old Street gives us drilling blind into a panel with reinforcement or a buried cable behind it, where 19% owner-occupation means the same home is booked again rather than a new tenant each year.
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.

Working in Old Street
In Old Street (EC1V) the split is 98% flats to 2% houses over 4,949 households, and the stock is post-war.
The social-housing-led mix here (19% owned, 28% privately rented) means a EC1V diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Expect often with surface conduit — and precast concrete panels and dense blockwork, measured on the walk in from Old Street (Northern, Great Northern) rather than assumed from a map behind the plaster in EC1V. That is why fixings are picked in the room rather than off a van shelf, and why Old Street gives us drilling blind into a panel with reinforcement or a buried cable behind it, where 19% owner-occupation means the same home is booked again rather than a new tenant each year is the fault we are called back to undo.
The roundabout, tech offices and warehouse conversions on the City fringe. That character decides the practical detail of cat flap fitting here far more than the borough boundary does. Old Street sits inside the Congestion Charge zone as well as ULEZ, so both are itemised on the quote rather than absorbed into an hourly rate.
Red-route roundabout with no kerbside loading, goods-lift booking in the towers and gated estate yards. Nearest station is Old Street (Northern, Great 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 Old Street on this side of Islington, with 4,949 households on this patch, and every job is quoted as a fixed written price before a fitter is booked. The material sets the price. Timber is quickest, uPVC and composite need capping on Islington bookings, with Islington parking rules in play, and a masonry wall means core drilling and a lined tunnel.

We check leasehold and landlord consent before cutting anything around Old Street (Northern, Great Northern) — and 4,949 households on this patch, with 28% of EC1V 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 Islington letting agents and managing agents ask for before work starts in a leasehold flat on EC1V jobs, with Old Street roundabout and Bunhill Fields burial ground a few streets away.
Cutting toughened or laminated glass on site — it must be replaced by a glazier; Fire doors in communal areas on this side of Islington — and 28% of EC1V homes being privately rented, with 52% social-rented stock nearby, where a cut-out would void the fire rating; Structural openings through a lintel or an insulated cavity closer without a survey.
