Builders in Portsmouth charge approximately £195–£385 per day in 2026. Single-storey extensions cost £29,000–£53,000. Portsmouth's high-density housing means extensions often require careful party wall agreements and planning consideration — always engage a structural engineer early for projects affecting shared walls.
Portsmouth plumbers charge £40–£70/hour in 2026. A new combi boiler supply-and-fit costs £2,100–£3,700. Gas Safe registration is mandatory for all gas work. Portsmouth's coastal location means boilers are often working harder due to cold sea winds — annual servicing is particularly important.
Portsmouth roofers charge £190–£375 per day in 2026. Portsmouth's exposed coastal position means roofs face higher wind loads than inland areas — always specify wind-uplift rated tiles and use BS 5534-compliant fixing. A full re-roof of a 3-bed terrace costs £5,500–£10,500 in concrete tiles.
