How to Choose a Home Adaptation Installer (Without Getting Burned)
Published 21 March 2026
DFG approval means your council trusts them. That's it.
When a council approves an installer for DFG work, they're saying: this company meets our minimum standards for insurance, competence, and building regulation compliance. They're on the list. That's not nothing — some companies don't make the list. But it's also not a gold star for excellence.
The quality of DFG-approved installers varies enormously. Some are specialists who've done thousands of adaptations. Some are general builders who occasionally fit a grab rail. The approval tells you they're safe to use. It doesn't tell you they're the best choice.
What actually matters
Adaptation experience. Ask how many DFG jobs they've completed in the last year. An installer who does fifty bathroom adaptations a year will do a better job than one who does five. They'll know the OT specifications. They'll know the council's paperwork. They'll know the common problems and how to avoid them.
TrustMark registration. TrustMark is the government-endorsed quality scheme. It's not mandatory, but it means the company has been independently assessed and carries appropriate insurance. If an installer isn't TrustMark registered, ask why.
Specific trade accreditations. For stairlifts: BHTA membership (British Healthcare Trades Association). For bathrooms: check they have qualified plumbers and electricians, not just general labourers. For structural work like ramps and extensions: check they're familiar with Part M of building regulations (access to buildings).
Get three quotes. Minimum.
Even with DFG work — where the council is paying — you should understand what the work involves and what it costs. If the council provides a contractor, you're entitled to request alternatives. If you're going through an HIA, they'll typically get quotes for you.
If you're paying privately (either because you don't qualify for a DFG or because you want work done faster), three quotes is non-negotiable. Not two. Three. The outlier tells you something — either two companies are overcharging, or one is cutting corners.
Red flags
No written quote. No fixed price — "we'll see how it goes." Reluctance to provide references. No public liability insurance certificate. Asking for full payment upfront. Pressure to commit quickly. Any installer who says "you don't need an OT assessment" for DFG work is either ignorant of the process or trying to bypass it. Either way, walk away.
The HIA shortcut
A Home Improvement Agency takes all of this off your plate. They vet the contractors. They get the quotes. They supervise the work. They handle snagging. It's a free, council-funded service that exists precisely because choosing and managing contractors is hard — especially when you're the person who needs the adaptation.
Not every area has an HIA. But if yours does, it's the single best decision you can make in the DFG process.
