Luxury bathroom and wet-room refurbishment in Edgware. Trusted, professional, 30+ years' hands-on experience.
GS Renovation renovates bathrooms across Edgware and the HA8 postcode, working within the 1930s semi-detached and interwar houses that fill the area. With more than 30 years of experience in Barnet, we deliver fully waterproofed bathrooms, wet rooms and en-suites, handling the tanking, drainage, tiling and finishing as one team.

A bathroom that lasts starts with proper waterproofing. In Edgware's interwar houses, where floors and walls can be uneven after decades of settlement, we tank the wet areas thoroughly before any tile goes on, so water never reaches the structure behind. For a wet room or walk-in shower, the tanking, the falls to the drain and the ventilation all have to be right, and we detail these carefully to avoid the damp problems that plague poorly built bathrooms.
We handle the drainage and extraction that older houses often lack, running new soil and waste connections and fitting effective ventilation to clear moisture. Underfloor heating can be laid beneath the tiles for comfort and to help the room dry, and we finish with fully tiled walls and floors. The result is a bathroom that stays dry, warm and sound in your HA8 home for years.
The bathrooms in Edgware's 1930s semis are often small and awkwardly shaped, tucked over the stairs or squeezed beside a chimney breast. We plan space-saving layouts that make the most of a tight period footprint, choosing sanitaryware and shower enclosures that suit the room rather than crowd it, and using the alcoves that interwar houses tend to offer.
Adding an en-suite to a main or spare bedroom is a popular upgrade in these houses, and we manage the new drainage, waterproofing, ventilation and electrics that it requires. The notifiable electrical work in a bathroom is carried out and certified under building regulations. From a compact en-suite to a full family bathroom, we deliver a watertight, well-ventilated room finished to a high standard across your Edgware home.
Edgware homeowners choose GS Renovation because a bathroom is only as good as its waterproofing and drainage, and we get those right first. We tank thoroughly, sort ventilation and falls, certify the electrics under building regulations, and finish with quality tiling and underfloor heating. With 30+ years across HA8 and Barnet, we build bathrooms that stay dry and look right in these interwar homes.

FAQ
The totals are usually closer than the structures behind them. A national firm subcontracts the bathroom renovation work in Edgware and prices its own overhead into your quotation, whereas GS Renovation carries out the HA8 job with its own team. That also means one named project manager rather than a call centre. Ask both quotations for the same itemised breakdown. Ring 07472 424 226 and GS Renovation will explain who would actually be on your HA8 site in Edgware. As a rough guide, bathroom renovation in London ranges from roughly £6,000 to £20,000 or more (indicative London ranges, MyBuilder and Checkatrade, 2026). Your figure depends on the size, specification and condition of the property, which is why we survey before quoting.
Yes, where drainage, structural or electrical work is involved, and in Edgware that goes through Barnet Council or a registered building control approver. Barnet took planning, highways, environmental health and building control back in house on 1 April 2023, when around 300 Re staff transferred to direct council employment. The council's building control duties also include statutory works under the London Building Acts (Amendment) Act 1939, covering dangerous structures, temporary structures and land searches. Replacing like for like fittings alone is not notifiable.
At the rear, yes, but Barnet's draft design guidance says front dormer windows will generally not be supported. The same guidance asks that chimney pots and stacks, party walls and ridge tiles be retained and worked into any first floor or two storey side extension. That matters when a soil pipe or a rooflight lands near the ridge. A rear dormer with the shower room against the party wall keeps drainage runs short and the front elevation unchanged.
Yes, subject to Policy CDH06, which tests the site's suitability against ground conditions, land instability, contamination and ground water before anything else. Barnet's draft guidance sets a minimum internal head height of 2.5 metres for habitable rooms, limits basements to a single storey and requires internal access from the main building rather than a separate entrance. Ground water is the practical risk here, so a tanked design and a sump with a pump are the honest baseline.
Yes near the brooks, because a point check at Edgware town centre returns Environment Agency records for both Flood Zone 2 and Flood Zone 3, and Barnet's Local Plan confirms surface water flood risk on the station site. New below ground drainage in those areas needs non return valves, and a ground floor WC set low can back up when the sewer surcharges. The drainage design should be agreed with the water authority before the floor is closed up.
No, local listing does not itself require listed building consent, so an internal bathroom refit is not caught. Barnet's Local Plan records over 1,250 locally listed buildings alongside over 670 statutory listed entries, and Policy CDH08 Part E treats them as non designated heritage assets subject to a balanced judgement on harm against public benefits. Original sanitary ware, tiling or a stained glass window still add value, so removing them is a choice, not a requirement.
