Luxury bathroom and wet-room refurbishment in Stevenage. Trusted, professional, 30+ years' hands-on experience.
A bathroom renovation is short but dense: drainage, ventilation, electrics, tanking and tiling all inside one small room. The order of work decides the finish. In Stevenage the drainage route and, for council tenants, the landlord's written permission are the two things to settle before the strip out begins.

Thames Water is the sewerage undertaker for Stevenage, and all wastewater and sewage from the town is treated at Rye Meads on the Hertfordshire and Essex border.
Moving a bath, shower or WC changes the falls on the waste and the connection into the stack. Where a new connection to the public sewer is involved, that is a matter for the undertaker rather than the council. We establish the drainage route at survey, before anything is taken out.
Tenants of Stevenage Borough Council must have the council's written permission before they carry out alterations or improvements to their home.
A bathroom replacement counts as an improvement, so the request goes in before a start date is agreed. We survey and quote while it is being considered, and hold the programme until the permission is confirmed in writing.
Bathroom work turns on drainage first and finishes second, because the waste route decides where the fittings can actually go. We survey the room, agree the layout against what the drainage allows, and run the trades as one sequence rather than in gaps. Building regulations work on drainage, ventilation and electrics is coordinated for you. The company is fully insured, quotations are free and without obligation, and you deal with one point of contact throughout.

FAQ
It covers the whole job through to sign-off. The document lists the structural work, the trades that follow, the Stevenage Borough Council inspections and the making good at the SG1 property, with the engineer's fee shown where bathroom renovation needs a design. Site protection and the daily clear-up are included. GS Renovation issues it in writing so a Stevenage homeowner has something to hold us to. Ring 07472 424 226 for a sample Stevenage layout before the SG1 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.
It can close off the quicker route. Hertfordshire Building Control states that a Building Notice cannot be used where you are building over or within 3 metres of a public sewer. The alternative is a full plans application, which is checked before work starts rather than allowing a start 48 hours after a notice. Establish where the sewer runs before the drainage layout is drawn, because the route decides the programme as much as the pipework does.
No. That programme is the council's own work in its own housing stock, with 209 homes upgraded in Wave 1, 237 in Wave 2 and a further 379 in Wave 3. A privately funded bathroom sits outside it, and nothing in the programme sets the specification, the fittings or the timing for one. If the council is your landlord, the alteration route runs through the council's written permission rather than through the fund.
The joists are checked before the bath is chosen. The local plan states that most of the town's buildings were built between the 1950s and the 1970s and are coming to the end of their useful life, and floor structures of that period were sized for the fittings of the time. A filled freestanding bath with an occupant is a heavy load concentrated in one part of the room. Where strengthening is needed, an engineer is appointed and we build to the calculations issued.
Either a registered electrician self certifying the work, or the building control body, which here is Hertfordshire Building Control Limited rather than the council. A bathroom counts as a special location, so circuits, bonding and the position of accessories all have to suit the zones around the bath and shower. The certificate belongs with the house records for a future sale. Inspection visits are booked by phone or WhatsApp, and we make those bookings.
