Water, sewer, electricity and broadband providers each have their own application process. [1] [2] [3] [4]
Start with a coordinated services plan
Show the proposed homes, entrances, boundaries and intended service routes. Prepare a schedule of the connections required and identify who will make each application, undertake work within the site and arrange the relevant inspections. Use the same unit and address references throughout. [1] [2] [4]
Confirm the actual provider for the address. Thames Water explicitly asks applicants to check that it supplies their water before applying; working in London does not mean every water-supply application goes to the same company. [1]
The relevant Future Homes and Buildings Standards provisions commence on 24 March 2027 for non-higher-risk work, with the separate higher-risk building provisions commencing on 24 September 2027, subject to transitional arrangements. These timetables inform the low-carbon services brief; they do not set a utility provider's connection charges. [8]
Water supply and drainage are separate applications
For a water connection, Thames Water asks for information including the fittings, site plan and proposed pipe entry point. Its quote distinguishes its work from pipework within the property boundary, for which the applicant is responsible. Work on third-party land also needs the relevant permission. [1]
For a sewer connection, identify the pipe sizes, proposed connection method, point of connection, levels and gradients. An indirect connection through a private drain requires the drain owner's permission as well as the sewerage company's consent. The physical drainage strategy should therefore be established before the final groundworks layout is fixed. [2]
Thames Water issues consent before connection work proceeds. For direct connections and manhole relocations, it requires inspection before backfilling and provides completion confirmation when the work is accepted. Do not arrange to conceal the connection before the inspection process has been settled. [5]
Electricity: distinguish temporary and permanent needs
UK Power Networks provides a connection route for one to four domestic or small-business properties and a separate temporary-connection route. A builders' supply should not be assumed to be the completed home's permanent arrangement. Request the appropriate connection assessment for the scheme. [3]
Coordinate the demand and equipment brief with the electrical designer. The new home's heating strategy and any required EV charging should be considered together rather than added independently after the connection application. The Future Homes Standard's 2027 provisions make the agreed low-carbon services strategy particularly relevant to new-home design. [6] [7] [8]
Broadband needs construction-stage planning
Openreach asks developers to register their site early and provide the location, number and type of plots, programme and plans. It expressly does not guarantee the requested availability date. Use the provider's requirements to plan the physical route and installation dependencies. [4]
Part R separately addresses gigabit-ready infrastructure and the network connection, with cost-cap and other provisions. An operator quotation and the building regulations assessment should be coordinated; neither is a substitute for the other. [9]
Track readiness and cost assumptions
Keep a connection schedule showing quotations, acceptance, on-site work, permissions, inspections and final connection dates. Thames Water also requires a verified official address for a new supply, so street naming and numbering belongs in the programme. [1] [10]
Connection costs depend on the assessed scope and provider arrangements. Use project quotations rather than a generic “utilities allowance”, and check their validity. Thames Water states that its charging arrangements are updated on 1 April each year. Confirm which charging arrangements and quotation terms apply to the proposed connection rather than assuming that a previous year's allowance is still sufficient. [1]
