Luxury bathroom and wet-room refurbishment in Potters Bar. Trusted, professional, 30+ years' hands-on experience.
A bathroom renovation is a services and waterproofing job with tiling on top of it. GS Renovation refits bathrooms in Potters Bar, including the drainage alterations and the making good, and coordinates building control where the work calls for it. Quotations are free and carry no obligation.

With a final inspection and a certificate. Hertfordshire Building Control asks that a final inspection is booked within five days of completion, and issues the completion certificate at no extra cost after a satisfactory inspection. We make that booking rather than leaving you to remember it once the tiler has gone.
The certificate is the record that the work was inspected. We hold the file open until it is issued, then hand it over with the rest of the paperwork at the end of the job.
48 hours after the notice is received. That is the position Hertfordshire Building Control sets out for the building notice route, so the notice is the first thing in the diary rather than the last.
Not every bathroom needs one. New or altered drainage, electrical work and anything structural are the elements that bring building control in, and we tell you at the quotation stage which of them apply to your job.
Bathrooms fail at the parts nobody sees, so the order we hold to is services first, waterproofing second, tiling last. We carry out the drainage alterations and the making good ourselves, and coordinate the building control inspections where the work needs them, so there is no gap between the plumber and the tiler for you to manage.

Email info@gsrenovationltd.co.uk with the EN6 address and we will book a free Potters Bar survey. 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.
The bathroom itself does not. The Royds design guide lists internal changes among the alterations that do not require planning permission in the conservation area. The daylight for it can be a different matter. Inside the Royds Article 4 area, planning permission is required for the installation of dormer extensions and rooflights to any roof slope, and for material changes to a roof including re-tiling. That is checked before the layout is fixed.
Yes, with approval and a design. Hertfordshire Building Control names removing chimney breasts as a structural alteration to an existing building that needs building regulations approval. Whatever is left above has to be supported or taken down. Inside the Royds Article 4 area planning permission is required as well, because it covers changes to any chimney, including its removal. Both are settled before the bathroom is priced.
It can, where joists have to be altered to drop the floor. Hertfordshire Building Control lists ground and floors and damp proofing among the matters its inspectors examine. Altering joists is structural work, so the engineer we appoint specifies it and we build to that. Where the floor is solid rather than timber, the question moves to the drainage falls and the tanking instead.
It can, and the position in Potters Bar is changing. Hertsmere Borough Council made a non-immediate Article 4 Direction on 23 April 2026 covering the Potters Bar Parkfield, Oakmere, Furzefield and Bentley Heath and The Royds wards. It would remove the right to convert a C3 dwelling to a C4 small house in multiple occupation without planning permission, and would come into force on 6 May 2027 if confirmed.
