How we work
Scoped and priced properly
Before any work begins you receive a clear, itemised quotation with scope agreed upfront. No vague estimates. No extras appearing once we are on site. Any variations are flagged and approved before they are carried out.
A defined programme
Every project has a start date, a completion date and a sequence of works planned around your operation. We work in live commercial environments and we treat your premises and your business accordingly.
Clean, organised sites
Commercial premises are live environments. We keep our sites tidy, minimise mess and disruption, and leave each area clean at the end of every working day. Your staff and customers shouldn't have to navigate a building site.
Commercial-grade finishes
We use appropriate systems for commercial use, not domestic trade paint applied quickly. Preparation is taken seriously because it's what determines how long a finish lasts and how well it holds up in a high-traffic environment.
Accredited and compliant
We hold Constructionline Silver accreditation and are SMAS registered. For facilities managers and procurement teams working to approved contractor lists, we meet the requirements.
Why Portsmouth Businesses Choose Cosgrove
We have been delivering commercial painting and decorating across Hampshire for over 25 years, with Portsmouth forming a regular part of our project workload. The city's commercial market is varied, and we are experienced in working within its different building types and operational constraints.
We hold Constructionline Silver accreditation and SMAS registration. These independently verified credentials are recognised by facilities managers and procurement teams across Portsmouth as confirmation that a contractor operates to an appropriate professional standard.

Why Cosgrove
01
25 years of commercial experience
Cosgrove Painting Contractors has been delivering painting and decorating work across Hampshire since the late 1990s. Our new build contracts, still the backbone of the business, have given us the scale, discipline and quality systems that smaller decorators simply haven't built.
02
Constructionline Silver accredited
We're registered with Constructionline at Silver level, giving facilities managers and procurement teams the assurance that our health and safety, financial and business practices have been independently verified.
03
SMAS accredited
Our SMAS accreditation confirms we meet the standards required for safe contracting in commercial environments.
04
A managed trade network
For refurbishment projects, we coordinate trusted subcontractors across decoration, tiling, flooring, joinery and certified plumbing and electrical trades. You get a single, joined-up project — not a series of separate contractors to manage yourself.
05
Owner-managed and accountable
Steve and Dominic Cosgrove run the business. When you work with Cosgrove, you're dealing with the people whose name is on the company. That matters when a decision needs to be made quickly or an issue needs to be resolved.
Covering Hampshire and the Surrounding Area
We work with businesses across Hampshire, including Southampton, Portsmouth, Winchester, Basingstoke, Fareham, Eastleigh, Chandler's Ford and the surrounding areas.
