Bathroom Renovation Canary Wharf

GS Renovation renovates bathrooms and en-suites throughout Canary Wharf, from older Docklands apartments to new-build riverside flats in E14. We handle waterproofing, tanking, drainage, tiling and underfloor heating, working within the building management rules that leasehold blocks require.

In Canary Wharf, a full bathroom refit typically costs £6,000 to £20,000 or more (indicative London ranges, MyBuilder and Checkatrade, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Canary Wharf: we carry the tanking, plumbing and tiling as one contract, with the electrics certified by a registered electrician.

How the job runs

1. Free design visit at your Canary Wharf home and an itemised quote.
2. Strip-out, then first-fix plumbing and electrics.
3. Tanking to the wet areas, then tiling.
4. Sanitaryware and second fix, with notifiable electrics certified by a registered electrician. Typically 10 to 15 working days on site.

Waterproofing bathrooms in Canary Wharf flats

In a Canary Wharf apartment, waterproofing is not optional, it is critical. A leak in a leasehold flat can damage the unit below and trigger disputes with the freeholder and managing agent, so we tank every wet area properly before tiling. Wet rooms and walk-in showers get full waterproof membranes, correctly falled trays and sealed junctions, giving you a bathroom that protects the whole block, not just your own home.

Drainage and ventilation take real planning in E14 flats, where you are tied to the building's existing soil stack and extraction routes. We set gradients carefully to keep waste flowing, fit proper mechanical ventilation to control moisture in a sealed apartment, and coordinate any noisier work with the managing agent so the rest of the development is not disturbed during the fit-out.

Housing in Canary Wharf

The Canary Wharf, Millwall and Cubitt Town statistical areas counts roughly 22,070 homes for Council Tax; 2% are older than 1919, 2% interwar and 95% post-war, with 92% flats and 8% houses. Where most homes are flats, a bathroom in a flat in Canary Wharf sits over a neighbour's ceiling, so tanking comes first.

New en-suites and building control in a Canary Wharf flat

Replacing a bathroom like for like in Canary Wharf is usually outside building control. Adding one is not. A new en-suite brings new waste pipes to the soil stack, new extraction and new circuits, and Tower Hamlets Council's building control service is responsible for ensuring that building work in the borough complies with building regulations. With 66% of Canary Wharf homes built in 2000 or later, the stack and the ventilation were designed around a set layout, so the application has to show how the new room connects without upsetting the flats above and below.

The electrics decide part of the fee. The council's domestic building control charges assume a Part P registered electrician, with a supplementary Part P charge in other cases, and a new en-suite often needs a shower circuit, a fan supply and sometimes electric underfloor heating. We have that work done and certified by a registered electrician, so the building control application covers the drainage and ventilation while the electrical side arrives with its own certificate. Keep that certificate with the completion certificate, because a Canary Wharf buyer's solicitor will ask for both.

En-suites and compact layouts for E14

Space is at a premium in many Canary Wharf apartments, so we design bathrooms and en-suites that use every centimetre. Wall-hung sanitaryware, walk-in showers and clever storage make a compact riverside en-suite feel generous, while underfloor heating frees up the walls and warms tiled floors without bulky radiators.

New circuits and electrical work near the bath or shower are notifiable, so the wiring is certified by a registered electrician under Part P, or notified to building control. We tile in quality porcelain or stone, seal thoroughly, and finish to a standard that suits the contemporary character of these E14 homes. Throughout, we respect the building's working hours and waste rules so the installation stays smooth for you and quiet for your neighbours in the block.
