Overview
This page prices cat flap fitting for London Bridge and Bermondsey Street SE1 specifically: Georgian and early Victorian stock, 29% privately rented and 4,532 households in total. Work starts at £75, fixed in writing, with parking and London Borough of Southwark 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
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. Market delivery windows before 09:00, railway-arch streets and booked goods lifts in the towers.
Most cat flap bookings are within 48 hours and take a single short visit. London Bridge (Northern, Jubilee, National Rail) is the nearest station, so a SE1 visit rarely needs a whole morning set aside.
We expect precast concrete panels and dense blockwork in London Bridge and Bermondsey Street, often with surface conduit — which is what a 95% flat share across the ONS neighbourhood covering London Bridge and Bermondsey Street actually produces in SE1, and we carry the anchors, through-fixings and long bits that match. The mistake we spend most time undoing here is drilling blind into a panel with reinforcement or a buried cable behind it on these streets — the pattern behind 4,532 households inside the SE1 neighbourhood.
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.
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. |

Working in London Bridge and Bermondsey Street
The SE1 stock around Borough Market is Georgian and early Victorian. ONS records 95% flats, 5% houses and 4,532 households in London Bridge and Bermondsey Street.
Owner-occupation runs at 21% in London Bridge and Bermondsey Street, so alongside the 29% rental churn there is steady planned work — refurbishments, downsizes and probate clearances booked weeks ahead.
Walls are precast concrete panels and dense blockwork in London Bridge and Bermondsey Street, often with surface conduit — which is what a 95% flat share across the ONS neighbourhood covering London Bridge and Bermondsey Street actually produces, so the fixing that matters in London Bridge and Bermondsey Street is chosen on site — the usual failure here is drilling blind into a panel with reinforcement or a buried cable behind it on these streets — the pattern behind 4,532 households inside the SE1 neighbourhood.
Anyone who knows London Bridge and Bermondsey Street knows the pattern near Borough Market: the Shard, Borough Market and the Georgian shopfronts of Bermondsey Street. We plan the SE1 visit around it. London Bridge and Bermondsey 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.
Getting to the door matters as much as the job: market delivery windows before 09:00, railway-arch streets and booked goods lifts in the towers. London Bridge (Northern, Jubilee, National Rail) 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 London Bridge and Bermondsey Street for London Bridge and Bermondsey Street (SE1) addresses, with 21% owner-occupation locally — and 29% of SE1 homes being privately rented, 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 Southwark bookings, with 5% of London Bridge and Bermondsey Street homes being houses, 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 Southwark, so the door stays weatherproof. If it is glazed, a glazier supplies a pane with the cut-out on SE1 jobs.
Yes, in writing. 29% of London Bridge and Bermondsey Street homes are privately rented around London Bridge (Northern, Jubilee, National Rail), with 95% of homes here being flats, and a flap cut without consent is a common deposit deduction. Send the email and we fit to its conditions on SE1 jobs.
Yes, from £190 for a wall up to 350mm — the usual answer in London Bridge and Bermondsey Street on the streets near Borough Market — and this being a short walk from London Bridge (Northern, Jubilee, National Rail), with 5% of London Bridge and Bermondsey Street homes being houses, where 95% of homes are flats with glazed back doors: we core-drill and fit a lined tunnel.
Fitters carry £5m public liability cover. We check leasehold and landlord consent before cutting anything in London Bridge and Bermondsey Street, with 21% owner-occupation locally, 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 Southwark letting agents and managing agents ask for before work starts in a leasehold flat on Southwark bookings, with Southwark parking rules in play.
Cutting toughened or laminated glass on site — it must be replaced by a glazier; Fire doors in communal areas across SE1 — and this being a short walk from London Bridge (Northern, Jubilee, National Rail), with 5% of London Bridge and Bermondsey Street 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 London Bridge and Bermondsey Street SE1 price you agree is the price you pay on this side of Southwark, with Borough Market a few streets away.
All three. With 29% of London Bridge and Bermondsey Street privately rented and 21% owner-occupied, roughly half the SE1 diary is agent- or landlord-instructed and invoiced separately from the person at the door on SE1 jobs — and 36% one-person households here, with this being a short walk from London Bridge (Northern, Jubilee, National Rail).
