How we work with you

ForrestBrown can help no matter where you are on your innovation journey. We offer advisory support to address specific innovation funding challenges, such as an HMRC enquiry into R&D tax relief or a grant application or negotiation. We also provide ongoing support to capture R&D activity in real time, horizon-scan for the latest government funding competitions, commercialise your IP with Patent Box and optimise your approach to capital allowances.

How we work with you

Our impact

We’ve helped clients secure more than £500 million to support innovation across R&D intensive sectors from aerospace to agritech.

But we don’t just measure success in tax relief received or grant offers made. Our advisory work has also helped clients protect their reputations, mitigate risks and improve financial planning.

The result: happy clients who are committed to working with us for the long term.

We draw on experience gained delivering more than 15,000 R&D tax claims for our clients.
