Question 1

What does a hip-to-gable loft conversion on a 1930s semi in Thornton Heath (CR7) or South Norwood (SE25) cost?

Accepted Answer

The hipped-roof semi-detached properties that define CR7 and SE25 typically see hip-to-gable loft conversion costs between £52,000 and £78,000, covering the gable rebuild, a rear dormer, rooflights, staircase, full insulation and Building Regulations certification. Adding a dedicated bathroom inside the new room costs roughly a further £8,000 to £14,000. Most 1920s–1930s semis across Thornton Heath and South Norwood qualify under permitted development, though obtaining a Lawful Development Certificate at the outset provides documented protection when the property is sold. We confirm the planning position during the initial survey and hand over a fully itemised written quote before leaving the site.

Question 2

Does a rear extension in South Croydon (CR2) or Purley (CR8) need planning permission from Croydon Council?

Accepted Answer

Under current permitted development rules, a single-storey rear extension on a detached house in CR2 or CR8 can extend to four metres without a formal application; three metres is the limit for semi-detached and terraced houses. Larger extensions — up to eight metres for detached and six metres for semi-detached or terraced — may be possible under the Neighbour Consultation Scheme, subject to prior approval and no valid objection from adjoining owners. Properties in Purley and Coulsdon that border the Green Belt or fall within a conservation area face additional restrictions. We check your plot boundaries and any Article 4 directions at the site survey before advising on the consent route or committing any costs to paper.

Question 3

How does PrimeCraft handle boiler and heating work on Croydon properties, and what certification is required?

Accepted Answer

All gas boiler replacements and heating system alterations across CR0, CR2, CR5, CR7, CR8 and SE25 must legally be carried out by a Gas Safe registered engineer. PrimeCraft Surface Solutions arranges this through a Gas Safe registered trade partner — no gas work is self-certified by unregistered operatives. The partner's Gas Safe registration number is confirmed in writing before any heating works are scheduled. We hold full public liability and employer's liability insurance for every other trade on the project, and the same-day itemised quote covers all scopes in one document, whether the job is a single bathroom refit or a whole-house renovation.
